The Code of Federal Regulations states: By taking steps to lower our risk across generations, we can ensure that our community recovers more quickly from the jurisdiction's commitment to reduce risks from natural disasters when they do occur. natural hazards,serving as a guide for decision makers as they commit resources to reducing the Mitigation builds community resilience and community effects of natural hazards." sustainability. This plan identifies hazards based on the (44 CFR Part 201.6,pp 8851) history of disasters and localized events within the City of Friendswood and lists goals, objectives, strategies and actions for reducing future losses. The implementation of planned, pre-identified, and cost-effective mitigation measures not only helps reduce losses to lives, property, and the environment, but it streamlines the disaster recovery process. Mitigation is commonly defined as sustained actions taken to reduce or eliminate long term risk to people and property from hazards and their effects. Hazard mitigation focuses attention and resources on community policies and actions that will produce successive benefits over time. Mitigation measures can include regulatory changes impacting development in natural hazard areas, infrastructure improvements, natural resource protection, education programs, and many others. Hazard mitigation aims to make human development and the natural environment safer and more resilient. Hazard mitigation generally involves altering the built environment to significantly reduce risks and vulnerability to hazards so that life and property losses can be avoided or reduced. Mitigation can also include removing the built environment from disaster prone areas and maintaining natural mitigating features, such as wetlands or floodplains. Hazard mitigation makes it easier and less expensive to respond to and recover from disasters by breaking the damage and repair cycle. The Federal Disaster Mitigation Act of 2000 requires all municipalities eligible to receive FEMA grant funding for hazard mitigation projects to adopt a local multi-hazard mitigation plan and update their plan in five-year intervals. The City of Friendswood received approval to develop its first Hazard Mitigation Plan with a FEMA approved mitigation planning grant in 2002. The City Council formally adopted the 2003 Hazard Analysis and Mitigation Plan on January 6, 2003. The five-year review and update of the City's Hazard Analysis and Mitigation Plan was adopted by City Council on November 2, 2009. This plan review and update will play an important role in the City's objective of protecting its citizen's health, safety and welfare. AUTHORITIES 44 CFR 201 AND 206 — Hazard Mitigation Planning and Hazard Mitigation Grant Program, February 2002 44CFR201.3 RESPONSIBILITIES (d) Local governments. The key responsibilities of local governments are to: (1) prepare and adopt a jurisdiction-wide natural hazard mitigation plan as a condition of receiving project grant funds under the HMGP, in accordance with §201.6. (2) At a minimum, review and update the local mitigation plan every 5 years from date of plan approval of the previous plan in order to continue program eligibility.

PLANNING PROCESS The planning process for the 2015 Hazard Mitigation Plan began shortly after FEMA approval was received for the 2009 Hazard Mitigation Plan. Since the adoption of the city's mitigation plan, mitigation team members also participated with the Galveston County Consolidated Drainage District in the development of their initial mitigation plan. The City of Friendswood is located in Galveston and Harris Counties. Requests for plan development assistance was extended via telephone requests and email to the Harris County Office of Emergency Management, Galveston County Office of Emergency Management, League City Office of Emergency Management, Pearland Office of Emergency Management, and the Galveston County Consolidated Drainage District. Presentations were also made through local community organizations; such as the Rotary Club, Friendswood Chamber of Commerce, State of the City Address by the Mayor to solicit individual participation. Solicitation for participants was also made through surveys on the city's website, at local community organization meetings, the local newspaper, the city's PEG channel. Although numerous requests have been made to solicit members of the community to participate in the mitigation planning process, only one resident has remained as a steadfast participating member throughout the mitigation planning process. However, participation is sporadic at best. Members of the Hazard Mitigation Planning Committee consist of the Mayor, Mayor Pro Tem, City Manager and all Departmental Directors of the City of Friendswood. All members of the committee participated in the planning process by submitting data, recommendations, and ideas for mitigation projects. Members of participant agencies gave input and ideas in those areas where cooperation and coordination would be needed to successfully address hazards and mitigation projects. 2015 HAZARD MITIGATION PLAN REVIEW&UPDATE COMMITTEE CITY OF FRIENDSWOOD -STAKEHOLDERS Terry Byrd Fire Marshal/Emergency Marshal/Emergency Management Coordinator Brian Mansfield Deputy Director, Fire Marshal's Office/Office of Emergency Management Roger Roecker City Manager Morad Kabiri, PE, AICP Assistant City Mana er/Director of Community Development Frank Mani old CFM Deputy Director Community Development Nick Haby Planning Mana er/PIO-Public Information Officer Kaz Hamidian Director Public Works James Toney Director Community Services Kevin Holland Ma or Rene Ibarra Deputy Director Projects &Engineering Cora Crews Deputy Emergency Management Coordinator Jim Hill City Council Member Steven Simmons Deputy Fire Marshal David Smith I Resident, City of Friendswood PARTICIPANTS-NEIGHBORING COMMUNITIES Bill Wheeler Deputy Emergency Management Coordinator, Harris County Office of Emergency Management Joseph Anderson Operations Manager, Galveston County Consolidated Drainage District 1 HAZARD MITIGATION PLAN - City of Friendswood Niki Bender Emergency Planning Coordinator, Galveston County Office of Emergency Management David Popoff Emergency Management Coordinator, Galveston County Office of Emergency Management Joshua Glover Harris County Office of Emergency Management Dena Mahan Emergency Management Coordinator City of League City The Annual Mayor State of the City Address, sponsored by the Friendswood Chamber of Commerce, makes available areas for city departments to display the status and progress of various projects. Educational materials regarding the mitigation process and status of the current plan are made available for attendees by the Office of Emergency Management/Fire Marshal's Office. The 2010 Mayor State of the City was held on March 4, 2010. Approximately 160 attendees, primarily members of the local Chamber of Commerce, attend this annual presentation. The first meeting of the Hazard Mitigation Plan Committee was held on April 7, 2010. The group discussed the removal of maps and other information or data which may be sensitive in nature to protect the city's infrastructure and that data which may be relative to homeland security issues. Attorney General Rulings are to be researched and those items within the HMP which could be utilized in terrorist incidents will be excluded from the public copies. Copies of the HMP will be distributed as follows: 1 complete copy available for the City Secretary's Office. The committee preferred not to charge a fee for a copy of the Mitigation Plan; therefore, a copy of the"public copy"will be available for review in-house at the Friendswood Public Library and City Hall with copies on compact discs for residents to take with them. Also, copies of the 2003 and 2009 Hazard Mitigation Plans will be available on the City of Friendswood website. Discussion held regarding distribution of educational materials to residents to keep them informed with respect to hazards affecting the city. Resource materials were obtained from "Ready.Gov" and were distributed to senior living centers/facilities, child care centers, animal clinics, Chamber of Commerce, and all city facilities. Excess materials were then provided to the City of League City and Nassau Bay and Clear Lake Council of Cities for use in their respective jurisdictions. Educational materials regarding the mitigation process and status of the current plan are made available for attendees by the Office of Emergency Management/Fire Marshal's Office. The 2011 Mayor State of the City was held on March 3, 2011. The second meeting of the Hazard Mitigation Plan Committee was held on October 6, 2011. Update was given as to the status of availability of public copies of the Mitigation Plan. Research was conducted with the Attorney General regarding the removal of sensitive materials, and a final public copy was produced and made available at City Hall and the Public Library. Educational materials regarding the mitigation process and status of the current plan are made available for attendees by the Office of Emergency Management/Fire Marshal's Office. The 2012 Mayor State of the City was held on March 1, 2012. On May 17"', 2012, the Hazard Mitigation Planning Committee met. Discussion included the updated records for new housing construction and commercial new construction and build-outs. Capital improvement projects were updated with the committee. The Texas Water Development Board (TWDB) is conducting a CRS review. Critical facilities protection measures were updated to the committee. Those water wells and lift stations that are not located within a designated flood zone have been equipped with natural gas generators. City Hall and the Public Library have had generators installed to maintain continuity of government during emergency situations. Windows have been reinforced at all city facilities to minimize damage as a result of various disastrous events. Training was provided by the State Library regarding the necessity to develop a Records Emergency Action Plan. A draft plan is in the development phase. A Continuity of Operations Plan (COOP) has also been drafted. The city still maintains an "Advanced Level of Preparedness"with the Texas Department of Emergency Management (TDEM). The city's Emergency Operations Plan and all supporting annexes are current and have been approved by TDEM. 2 HAZARD MITIGATION PLAN - City of Friendswood In January 2013, members of the Mitigation Planning Committee attended mitigation training provided through the State of Texas Division of Emergency Management. The courses presented included G-710: Mitigation Planning Course and G-393: Mitigation for Emergency Managers. The primary focus of Mitigation Planning Course was to address 44CFR 201.6 (Hazard Mitigation Planning and Hazard Mitigation Grant Program) with emphasis on requirements for mitigation plans and the revised crosswalk to ensure local mitigation plans address all issues of the regulation. January 31, 2013, the Mitigation Planning Committee met with the primary focus of the review of the current plan to ensure that all requirements of 44 CFR 201 are addressed in the current plan. A presentation was made regarding the highlights of the new regulations and mandatory requirements, addressing deficiencies in the current plan, emphasis on public participation, participation of stakeholders within the community, and incorporation of the mitigation plan into other planning mechanisms utilized by the city (i.e., capital improvements plan, drainage plans, floodplain plans). The committee updated the city's risk assessment/vulnerability analysis. Those hazards receiving the highest ranking were severe thunderstorm/hail/lightning, flood events (flash and riverine) and hurricane —wind. Hazardous material events with regard to pipelines also received high ranking. The process used for the assessment utilized the vulnerability of the community to a hazard and the frequency of the occurrence of such event. Educational materials regarding the mitigation process and status of the current plan were made available for committee members by the Office of Emergency Management/Fire Marshal's Office. A Hazard Mitigation Plan Survey was developed and posted on the city's webpage. Two surveys were developed, one directed at business owners and one directed to homeowners. This survey was capable of being completed on-line and submitted via email to the Office of Emergency Management. A copy of the posting on the City's website, questionnaire and the results can be found in APPENDix B. The 2013 Mayor State of the City was held on March 7, 2013. Along with the educational materials, copies of the business owner hazard mitigation survey were distributed and collected after the meeting. A member of the Hazard Mitigation Committee delivered a mitigation awareness program at the Friendswood Rotary International organization on May 15, 2013. Copies of the hazard mitigation survey were distributed and collected from the 24 attendees. The Hazard Mitigation Committee met again on January 20, 2014. Discussion was held around the draft submitted to the committee and development of mitigation action items. During the development of the plan update, draft copies of the Hazard Mitigation Plan were distributed to committee members via email. Members of the city's mitigation committee also participated in planning meetings during the development process of the Galveston County Consolidated Drainage District Hazard Mitigation Plan. City of Friendswood committee members participating with the Drainage District were Morad Kabiri, Rene Ibarra, Cora Crews and Niki Bender. Copies of the Hazard Mitigation Committee meeting agendas, signature pages, and the hazard mitigation surveys are located in APPENDIxA. COORDINATION WITH OTHER PLANS During the plan update process, existing documents were referenced to ensure that the Hazard Mitigation Plan goals and activities are consistent with planning that has already occurred. 3 HAZARD MITIGATION PLAN - City of Friendswood The following plans were utilized in the review process: • City of Friendswood Capital Improvements Plan (CIP) The CIP was utilized to document the status of current and proposed improvements to city facilities and infrastructure to emphasize protection measures designed to alleviate the effects of future hazards. • City of Friendswood, Master Drainage Plan-Phase II, 2007 The Master Drainage Plan details the protection measures to be put into place to alleviate flooding hazards during minor and major weather events • Vision 2020 This plan was utilized to assist with the city's current status and growth projections to maintain the quality of life envisioned by the strategic planning committee. This plan details economic status and projections, land use (residential and commercial), population density, and future development. • City of Friendswood, Drought Contingency Plan This plan details strategies to ensure continued water access and preservation. • State of Texas, Hazard Mitigation Plan, 2013 Update This document was used as a reference to ensure that the city's mitigation planning process was compliant with the state example. • Galveston County Consolidated Drainage District Hazard Mitigation Plan, September 24, 2013 The Galveston County Consolidated Drainage District (GCCDD) is a partnering agency with the city assisting with drainage projects and mitigation efforts. The GCCDD and the city partner together to develop, design and complete drainage projects throughout the city. PUBLIC PARTICIPATION Approved copies of the 2015 Hazard Mitigation Plan will be made available to the public at the Friendswood Library and City Secretary's Office. The approved plan will also be placed on the city's website available for the public's review. Public information fliers will be available at public emergency management presentations to educate the public about the importance of public and private mitigation practices. EVALUATION AND UPDATING THE MITIGATION PLAN Due diligence is warranted on a daily basis to ensure that all data located in the plan is maintained and updated through each year following adoption of the plan. Semi-annual to annual hazard mitigation committee meetings will be held to assess the progress and status of the current mitigation action items and to develop future mitigation action items. 4 HAZARD MITIGATION PLAN - City of Friendswood SECTION II HAZARD MITIGATION STRATEGY The City of Friendswood Hazard Mitigation Committee identified a number of mitigation measures that would serve to reduce the city's vulnerability to natural or man-made hazardous events. These include infrastructure improvements such as continued maintenance and repairs which may arise with regard to generators on all public facilities, water wells, surface water stations, lift stations, and public education efforts relating to all natural hazards potentially impacting the city. Overall, the hazard mitigation strategy recognizes that mitigating hazards for Friendswood will be an on- going process as our understanding of natural hazards and the steps that can be taken to mitigate their damages changes over time. Various factors impact the city's vulnerability, and local officials will need to work together across municipal lines and with state and federal agencies in order to understand and address these changes. The Hazard Mitigation Strategy will be incorporated into other related plans and policies. HAZARD MITIGATION STRATEGY AND GOALS 1. Ensure that critical infrastructure sites are protected from all hazards. 2. Reduce the vulnerability from flooding of existing residential and business structures. 3. Maintain previous mitigation projects to ensure continuity of services. 4. Continue to enforce existing zoning and building regulations. 5. Educate the public regarding zoning and building regulations which affect new construction, demolition, and flood hazards. 6. Work with surrounding communities to ensure regional cooperation and solutions for hazards affecting multiple communities, such as flooding. 7. Continue to develop capital improvements projects which address hazards identified in the mitigation plan. 8. Maintain the city's ability to respond to all types of hazards. 9. Develop, maintain, and update a viable public information network to ensure that residents and commercial interests are aware of the various sources of information regarding impending emergency and/or disaster events (i.e., Facebook, Twitter, E-mail, City Website, CodeRed, Radio, etc.) s HAP M MIUGAUOX PLM — myOfrll eswooe le HAZARD MITIGATION PLAN - City of Friendswood SECTION III HAZARD IDENTIFICATION AND RISK ASSESSMENT OVERVIEW OF HAZARDS The City of Friendswood is exposed to many hazards, all of which have the potential to disrupt the community, cause casualties, and damage or destroy property. The process of identifying hazards is two-fold. FIRST • A hazards analysis is developed. It is a stand-alone product consisting of maps, databases, charts, atlases, and other supporting documentation. The analysis provides a risk-based quantitative method to prioritize mitigation and preparedness needs for the jurisdiction as a whole. This analysis is reviewed and updated frequently. SECOND • A mitigation action plan is developed. The mitigation action plan outlines mitigation goals, identifies a risk reduction strategy for each of the significant hazards that threaten the area, and discusses the on-going risk reduction activities undertaken within the jurisdiction. The mitigation action plan further details what is to be done, how much it will cost, who will be responsible for the action, how it will be funded, and provides an implementation schedule. The City of Friendswood recognizes that the community will continue to be exposed to and subject to the impact of hazards as described in this document as well as hazards that may develop in the future. The potential exists for a major disaster to occur at any time and at any place. In many cases dissemination of warning to the public and implementation of increased readiness measures may be possible, yet some emergency situations occur with little or no warning. During the 2014 Plan update the Mitigation Committee updated the Risk Assessment/Vulnerability Analysis with reference to natural and man-made hazards. The Hazard Mitigation Committee reviewed the hazards included in the 2009 Mitigation Plan, along with the historical aspect of past events, and updated the Risk Assessment &Vulnerability Assessment. Although the 2009 Hazard Mitigation Plan did not rank or prioritize the potential hazards based upon historical data, frequency or vulnerability, the Hazard Mitigation Committee did complete a Risk Assessment/Vulnerability Analysis during the review process for the 2014 Mitigation Plan. The results of that analysis can be seen in Table 2 of this Section. Hazards were prioritized based upon the total vulnerability and frequency within the city, and then each hazard was explained, updated with information from the latest Mitigation Plan, and further analyzed. The listing in the following paragraph depicts the priority of hazard s based upon the Risk Assessment/Hazard Analysis. The following hazards were assessed in the 2009 Mitigation Plan, and were reviewed again for the 2014 Mitigation Plan update: • Flood events (flash and riverine) • Hurricane (storm surge) & hurricane (wind) • Tornado • Severe thunderstorm/hail/lightning • Drought • Subsidence • Winter storms • Hazardous materials/pipeline and/or fixed facility A variety of sources were utilized to identify past natural hazard events for the City of Friendswood. Some of these sources included the National Oceanic Atmospheric Administration (NOAH) National Climatic Data Center (NCDC) database, the Natural Hurricane Center's Hurricane Tracker database, and Hurricane Consulting. Review of past natural hazard events for the City of Friendswood noted for those events which were included in the 2009 Mitigation Hazard Plan, and those events which have occurred 7 HAZARD MITIGATION PLAN - City ofF/%en(ISWOOd since adoption of the latest version of the City's Mitigation Plan.

HAP M MIUGAUOX PLM — myOfrll eswooe le • M HAZARD MITIGATION PLAN - City ofF/%endswood SEVERE THUNDERSTORM/HAIL/LIGHTNING THUNDERSTORM/HIGH WIND Severe weather incidents which include thunderstorms, hail, lightning, and high winds have occurred within the community. Several meteorological conditions can result in winds x' severe enough to cause property damage. Winds have been associated with extreme hurricanes traveling inland, tornadoes, and locally strong thunderstorms. Thunderstorms are the by-products of atmospheric instability, which promotes vigorous rising of air particles. A typical thunderstorm may cover an area _ three miles wide. In Galveston County, most wind damage has been limited to downed trees, blocked roads, and disabled power lines. Single cell thunderstorms are sometimes referred to as "airmass","popcorn", or"pulse" thunderstorms, and usually do not produce severe weather. They often form in regions of warm, moist air with no strong fronts in the area. Each thunderstorm follows the life cycle of a typical thunderstorm with development, maturity, and decay occurring over a period of 30 minutes to an hour. They may contain heavy rain and can also produce occasional downbursts, small hail, and (rarely)weak tornadoes, but these are fairly rare in single cell storms. Multi-cell clusters are basically what the title says; a cluster of thunderstorms that form and move together. When a single cell thunderstorm forms, it produces a downdraft that can create a gust front of cool air near the ground. The gust front contains denser air than its surroundings, and as it spreads out, it lifts'the surrounding warm air around it. That lift' may be just enough to create another updraft which would lead to the formation of one or more additional thunderstorms. This cycle can repeat itself for hours before the cluster of thunderstorms finally dies down. LOCATION Thunderstorms/high wind events have the potential to affect the entire planning area. Historically thunderstorm/wind events have been infrequent and sporadic in effect on the city. Thunderstorms associated with lightning, hail, tornado, and flash flooding are addressed separately. PREVIOUS EVENTS&EXTENT It is difficult to predict the area where a thunderstorm/high wind event may occur, or the duration of such a storm, therefore, all buildings and facilities are considered to be exposed to these hazards and could potentially be impacted. PREVIOUS EVENTS The NCDC database indicates that between 1950 and 2015, Galveston County experienced 313 thunderstorms. Of those 313 events, 97 had winds in excess of 57 mph or higher. Of the 23,920 days during the study period, 130 days experienced an event (.005%), with the highest wind speed of 62 mph. Of the three (3) events which affected the city(.0001%), total damages recorded are $118,000. The NCDC indicates that no thunderstorm/high wind events have occurred in the city since the 2009 Friendswood Hazard Mitigation Plan. Also note that the thunderstorm and winds category of the NCDC database excludes hurricane wind events. Is HAZARD MITIGATION PLAN - City ofF/%endswood EXTENT Based upon data available for past events, it can be expected that the city will experience minimal damage in future thunderstorms. Assuming that wind speeds would be in the 57 to 62 mph range, damages are expected to be minimal. As noted above, the chance of damages from a severe thunderstorm/wind event to affect the city is .0001%. Although the potential exists that a severe thunderstorm/wind event could affect the entire city, approximately 12,961 structures are vulnerable to damage. However, damages could involve downed fences and uprooted trees which do not always cause damage to the built environment; missing roof shingles; damage to tar roofs, etc. Damages reported by the NCDC do not specify what damages were incurred, but include an estimate of the damage by reports received by the NWS. The Community Development Department for the city issues building permits for remodel and repair construction, but does not specify what caused the damage, therefore, it is difficult to anticipate estimated structural damages if such an event effected the city. Using an assumption that damages affect 1% to 5% of the structures, 130 to 648 structures could potentially receive damage. Damage estimates are difficult to anticipate based upon the type of material that would be required to make repairs to roofs (shingle, tile, torch-down, etc.), fencing material, debris removal of vegetation, current market cost of materials, and labor costs.

Based upon data available for past events, it can be expected that the city will experience minimal damage in future thunderstorm/hail events. As noted above, the chance of damages from a thunderstorm/hail event to affect the city is .00021%. Although the potential exists that a severe thunderstorm/hail event could affect the entire city, approximately 12,961 structures are vulnerable to damage. However, damages could involve downed damaged roofs and vehicles. Since Friendswood is not classified as an agricultural area, crop damages expected to be negligible. Damages reported by the NCDC do not specify what damages were incurred, but include an estimate of the damage by reports received by the NWS. The Community Development Department for the city issues building permits for remodel and repair construction, but does not specify what caused the damage, therefore, it is difficult to anticipate estimated structural damages if such an event effected the city.

Lightning damage results from four effects of the lightning strike: electrocution of humans and animals, vaporization of materials along the path of the strike, fire caused by the high temperature produced by the strike, and a sudden power surge that can damage electrical and electronic equipment. Millions of dollars of direct and indirect damages result from lightning strikes on electric utility substations and distribution lines. While property damage is the major hazard associated with lightning, it should be noted that lightning stakes kill more people each year than either tornadoes or hurricanes. Since it is difficult to predict where lightning might stake, all buildings and facilities are considered to be exposed to these hazards and could potentially be impacted. PREVIOUS EVENTS&EXTENT According records available from the National Lightning Detection Network— NLDN (operated by Vaisala, Inc.), data of cloud-to-ground flash densities for the State of Texas indicates 11.4 Flashes per square mile,with a total of 3,025,808 flashes per year. PREVIOUS EVENTS NCDC records indicate six (6) lightning strikes in Galveston County for the period of 2008 through October 31, 2013. Of these 6 reports, 5 were located in the southem portion of the county. The nearest recorded lightning strike to the city was located in west League City. No lightning stakes were recorded for the City of Friendswood during this period. As indicated by the figures below, the flash density for the city ranges in the 12-20 flash density per square mile in the lower portion of the city, with a flash density in the range of 20-28 in the northeastem portion of the city. With the City of Friendswood encompassing 23 square miles, the potential exists for up to a density of 262 stakes per year. T_T Xakoml Lightning ad<xon 20M xrtxcex VAISALA Galveston Friendswood County 19 HAZARD MITIGATION PLAN — City of Friendswood EXTENT BUILT ENVIRONMENT The entire city is vulnerable to thunderstorm/lightning events. The NCDC database shows that between 1950 and 2015, Galveston County experienced 13 thunderstorm/lightning events (.00054%). According to fire response records for the Friendswood Volunteer Fire Department, two (2) residential structures were struck by lightning resulting in a fire. Damages were estimated at $441,000 (based upon assessed valuation per the Galveston County Appraisal District). Assuming that one percent (1%) of structures per year could be affected by a lightning strike during such an event, damages may potentially amount to $2,973,018. Historical lightning events have ranged in the LAL 4— LAL 5 level as explained by the Lightning Activity Level on the NOAA website listed below. HUMAN ENVIRONMENT No previous incidences have occurred in the city where people have been injured or killed when outside during a lightning storm. However, the City of Friendswood boasts 10 park areas with a total of 265.71 acres. This does not include the outdoor park areas located at the Friendswood school facilities. The city hosts numerous activities in the city's parks throughout the year and is diligent in cancelling events should the potential exist for lightning and/or hail storms. People are vulnerable to lightning strikes when they are outside, especially in wooded areas and open areas, such as soccer, football and baseball fields. Public information materials are available for lightning safety while outside and are posted on the city's website, via Twitter and Facebook. The Parks Department is also very diligent in working with the Office of Emergency Management to obtain updated weather conditions and will cancel all outdoor events should potential dangerous weather conditions exist, especially where the potential for lightning exists. The LIGHTNING ACTIVITY LEVEL is a common parameter that is part of fire weather forecasts. LAL is a measure of the amount of lightning activity using values 1 to 6.

In an effort to mitigate the impact of severe weather within the community, the city provides public outreach programs aimed at increasing family disaster preparedness. The Emergency Management Office submits materials to be published in the annual Focus on Friendswood Hurricane Preparedness Hewsietterwhich is distributed to all Friendswood residents. The Emergency Management Office participates in emergency management training, exercises, drills, Severe Weather Awareness Week in the spring of each year, and the annual TDEM Hurricane Exercise. Through participation in emergency management exercises, Emergency Management staff members are able to evaluate their capabilities and preparedness status. Constant examination and evaluation of the emergency management functions within the city are a valuable mitigation strategy. To protect the public utilizing the community swimming pool and the various designated sports areas,the Community Development Department conducts annual training sessions for all staff members to be cognizant of impending weather developments (severe thunderstorms, lightning, etc.) and to cease all activities when a potential danger exists. Emergency Management Officials encourage citizens to purchase and utilize weather radios as a mitigation strategy for the individual. Weather radios are also placed in city facilities, educational facilities, and congregate care facilities within the city limits. Additional sources for obtaining weather information include local television stations, City of Friendswood PEG Channel 17, Friendswood Information Radio 1640 AM in addition to Houston radio broadcasts, e-mail alerts from the city, and the FirstCall Emergency Notification System. 2009 MITIGATION ACTION ITEMS PUBLIC WARNING SYSTEM • Utilize available warning systems to inform the public of impending severe thunderstorms, hail storms and potential possible damage from lightning strikes The city utilizes the following systems to broadcast public service announcements: • Radio: Friendswood Information Radio 1650 AM KTRH 740 AM (EAS) STATUS • Television: City of Friendswood PEG Channel 17 &all Houston local stations Ongoing • E-mail Alerts available at www.friendswood.com • Outdoor Warning Siren System (7 sirens) • Storm Spotters (a requirement of"Storm Ready Community" classification), in conjunction with the National Weather Service and the city conducts Storm Spotters Classes on a bi- annual basis. 21 HAZARD MITIGATION PLAN — City ofF/%en(ISWOOd UPGRADE PUBLIC WATER SYSTEM Equipment to provide a consistent supply of safe water during extended power outages following hurricanes, flood events, severe weather events, etc. WATER PLANT#5 • Replace elevated tank&ground storage tanks with concrete • Completed 2011 tanks + new generator WATER PLANT#6 • Install 500,000 gallon steel water tank, new pump house, • In final stages of construction emergency generator WATER PLANT#7 • Replacement of control room, chemical room, conversion of • Projected completion in pumps, all valves/piping, replace existing 210,000 existing FY2014 tank with 500,000 gallon steel unit • Purchased an additional 6 M gallons surface water from the City of Houston. • The citv has also added 30 fire hydrants to the system within the past five 5 ears. • Installed PVC transmission lines to replace large sections of old water lines; strategic connections and increased certain line sizes to improve pressure and water quality.

Regional Treatment Plant 22 HAZARD MITIGATION PLAN - City ofF/%endswood FLOOD EVENTS Historically floods are and continue to be one of the most frequent destructive and costly natural hazards. Floods are a natural and recurrent event. Floods take place every year and in all seasons. Flooding is a localized hazard that is generally the result of excessive precipitation. Flooding events are usually broken down into three different categories: flash floods, riverine floods, and tidal floods. Given present knowledge, the size,time, and place of floods cannot be predicted more than a few hours in advance. Floods are generally the result of excessive precipitation, and can be classified in two broad categories: general and flash floods. FLASH FLOODING Flash floods are the product of heavy localized precipitation falling in a short time period over a given location. Flash floods occur within a few minutes or hours of heavy amounts of rainfall, from a dam or levee failure, or from a sudden release of water held by an ice jam. Flash floods can destroy buildings and bridges, uproot trees, and scour out new drainage channels. Most flash flooding is caused by slow- moving thunderstorms in a local area or by heavy rains associated with hurricanes and tropical storms. GENERAL FLOODING General floods are defined as precipitation over a given river basin. General floods are usually long-term events that may last for several days. The primary types of general flooding include riverine, coastal, and urban flooding. RIVERINE FLOODING is a function of excessive precipitation levels and water runoff volumes within the watershed. Coastal flooding is typically a result of storm surge, wind-driven waves, and heavy rainfall produced by hurricanes, tropical storms, nor'easters, and other large coastal storms. Urban flooding occurs when development has obstructed the natural flow of water and decreased the ability of natural groundcover to absorb and retain surface water runoff. The recurrence interval of a flood is defined as the average time interval, in years expected to take place between the occurrence of a flood of a particular magnitude and an equal or larger flood. Flood magnitude increases with increasing interval. COASTAL FLOODING is typically a result of storm surge, wind-driven waves, and heavy rainfall. These conditions are produced by hurricanes during the summer and fall, and nor'easters and other large coastal storms during the winter and spring. Storm surges may overrun barrier islands and push sea water up coastal rivers and inlets, blocking the downstream flow of inland runoff. COMBINED RIVERINE AND COASTAL FLOODING Certain areas are affected by both riverine and coastal flooding. As subsidence occurs in these areas, the depth of riverine flooding tends to remain constant, while the depth of coastal flooding increases. For floodplain management and flood insurance purposes, criteria used in coastal areas should be applied in areas of combined riverine and coastal flooding. Clear Creek divides Harris and Galveston Counties. It is subject to combined probability flooding from riverine and coastal/tidal flooding. No home construction is allowed within Zone A areas until the property owner completes a study to determine the BFE (base flood elevation) of the parcel. Based upon the results of the BFE, the parcel is then zoned appropriately and construction elevation is then based upon that determination. URBAN FLOODING entails the flooding of streets, underpasses, low lying areas, or storm drains. This type of flooding is mainly an inconvenience and is generally not life threatening. Flood hazard areas are determined using statistical analyses of records of river flow, storm tides, erosion, wave heights, and rainfall; information obtained through consultation with the community; floodplain topographic surveys; and coastal, hydrologic, and hydraulic analyses. The Flood Insurance Study covers those areas subject to flooding from rivers and streams, along coastal areas and lakeshores, and/or shallow flooding areas. 23 HAZARD MITIGATION PLAN— City of Friendswood As described in the April 20,2000, Harris County Flood Insurance Study, the City of Friendswood and Harris County are subject to intense local thunderstorms of short duration, general storms extending over periods of several days, and torrential rainfall associated with hurricanes and other tropical disturbances. The National Climatic Data Center(NCDC) of the National Oceanographic and Atmospheric Administration (NOAA) maintains historical data for numerous hazards facing the United States. Records from the NCDC indicate that Galveston County experienced eight(8) flash flood events from January 1, 2008 through October 31, 2013. The City of Friendswood has experienced 4 Riverine/Flash floods prior to 2008. The two flash flooding events within the city since 2008 occurred April 18 and April 24, 2009. Heavy rainfall from thunderstorms produced widespread flooding of roads. Although Clear Creek at FM 528 was out of its bank, no report of flooding of homes in Friendswood was reported; however high water rescues were conducted in Dickinson to the south, and over 300 homes in League City to the east sustained flood damage in homes. property damage estimates for this event were $4 million. Flooding from stone surge (hurricane event) has been recorded five (5) times within the city prior to 2008, and no flooding events from stone surge have occurred within the city since 2008. Two storm surge/flooding events occurred within Galveston County on August 5, 2008, as a result of Tropical Stone Edouard and September 12-14, 2008, following Hurricane Ike. The storm surge was primarily located in the southern most portion of the county. FIGURE 1 STORM SURGE—HURRICANE IKE Hurric rg ane Ike Storm some Galveston County y _ i � ee City of Friendswood 24 HAZARD MITIGATION PLAN - City ofF/%endswood STORM SURGE SCALES AND FORECASTING Prior to the 2009 hurricane season,the National Hurricane Center predicted storm surge levels based on the hurricane wind speed category. A storm surge is a large dome of water often 50 to 100 miles wide and rising from 4 to 5 feet upwards to 20 feet. In 2015 NOAA's National Hurricane Center will offer an experimental graphic to highlight those areas along the Gulf and Atlantic coasts of the United States most at risk for life-threatening inundation by storm surge from a tropical cyclone. The new graphic is designed to introduce the concept of a watch or warning specific to the storm surge hazard, displaying areas that would qualify for inclusion under a storm surge watch or warning system currently being developed by the National Weather Service. As part of a phased implementation plan, experimental storm surge watches and warnings are expected to debut in 2016. After incorporating both user and partner input, the NWS expects to make the new storm surge warning system fully operational in 2017. The storm surge arrives ahead of the storm's actual landfall and the more intense the hurricane is, the sooner the surge arrives. Water rise can be very rapid, posing a serious threat to those who have not yet evacuated flood-prone areas. The surge is always highest in the right-front quadrant of the hurricane. As the storm approaches shore, the greatest storm surge forms to the north of the hurricane eye. The surge of high water topped by waves driven by hurricane force winds can be devastating to coastal regions, causing severe beach erosion and property damage. According to historical records from the National Climatic Data Center, the City of Friendswood has not experienced flooding related to storm surge. However, it should be noted that if the tropical storm has high storm surge along with heavy rainfall, flooding could be experienced in the city along all the creeks and drainage areas. The Federal Emergency Management Agency(FEMA) has classified the city as a Category"C" Repetitive Loss Community; therefore, as a condition of participation in the Community Rating System (CRS) Program, FEMA requires a Category"C" community to adopt a floodplain management plan that addresses all hazards within the community and not limited to only repetitive loss areas. The Community Rating System (CRS) indicates the city received a Class Nine (9) CRS Community designation by FEMA on June 1, 1991; upgraded the rating to Class Eight (8) CRS Community on October 1, 1993; and received a Class Five (5) CRS Community rating on October 1, 2003, and maintained the CRS Class 5 rating per the Community Assistance Visit (CAV) visit on September 18, 2007. As of June 2013, the CRS rating is at 5. The city has participated in the National Flood Insurance Program (NFIP) since June 5, 1970 (Emergency Program) and since March 3, 1972 (Regular Program). To remain in compliance with the NFIP, the city has adopted the following Flood Damage Prevention Ordinances: TABLE 6 FLOODPLAIN ORDINANCES FLOODPLAIN ADOPTION DATE ORDINANCE# No. 175 March 5, 1973 No. 304 June 5, 1978 3-83 April 4 1983 87-10 May 4 1987 90-19 September 20 1990 90-26 October 15 1990 91-27 February 26 1991 98-36 December 7 1998 99-30 September 27, 1999 03-08 July 7, 2003 07-20 December 17, 2007 The city is mitigating the impact of flooding within the community. The current impact has been greatly reduced from what it was ten years ago. Cooperative projects with the Galveston County Consolidated Drainage District and Harris County Flood Control District seek to reduce flood losses. Acquisition projects 25 HAZARD MITIGATION PLAN - City of Friendswood such as the Hazard Mitigation Grant Program (HMGP) following Tropical Storm Allison have reduced the number of persons exposed to flood hazards. In April 2008, the city conveyed an easement to the GCCDD over a buy-out tract for the purpose of in-line detention on Mary's Creek. City officials continue to encourage the purchase of flood insurance as a mitigation measure for individuals in the community. Flood insurance policies are available to all residents of the City of Friendswood. Because the City of Friendswood participates in the CRS program, flood insurance policy holders pay reduced premiums. It is important to note that flooding has damaged additional properties but exact records are not known because the properties and losses were not covered by flood insurance. Neither FEMA nor the TDEM has records that identify all flooded properties within the city. DEFINITIONS OF FEMA FLOOD ZONE DESIGNATIONS Flood zones are geographic areas that are defined according to varying levels of flood risk. Special Flood Hazard Areas (SFHA) zones are depicted on a community's Flood Insurance Rate Map (FIRM) or Flood Hazard Boundary Map (FHBM). The SFHA is a high-risk area defined as any land that would be inundated by a flood having a 1% chance of occurring in a given year (also referred to as the base flood). The SFHA is the area where the National Flood Insurance Program's (NFIPs) floodplain management regulations must be enforced and the area where the mandatory purchase of flood insurance applies. The SFHA includes Zones A, AO, AH, Al-30, AE, A99, AR, AR/A1-30, AR/AE, AR/AO, AR/AH, AR/A, VO,V1-30, VE, and V. Each zone reflects the severity or type of flooding in the area. For further information regarding the description of each flood zone; see htto://std b learning center.com/uo loads/fema-flood-zone-d efin itions.odf The public becomes aware of local hazards in various ways. For example, public awareness of flood hazards is enhanced during the following activities: • Buying property in a floodplain triggers the federal requirement to obtain flood insurance. Federally insured and regulated mortgage lenders are required to inform the potential homeowner of the necessity of purchasing flood insurance if the building is located in a mapped flood hazard area. • Applying for permits will lead to the determination that the property or construction site is within a mapped floodplain and is subsequently subject to floodplain management requirements. • When flooding occurs the news media frequently advises the public of travel which is hampered by flooded roads and homes which may be damaged by floodwaters. Research has shown that many flood victims tend to discount the likelihood that flooding will occur again. This tendency is attributed to a general lack of understanding of probability. Often people interpret the phrase"100-year storm" to indicated it only occurs once every 100 years, rather than such an event has a 1-in-100 chance of happening each year. • Flood warnings reach the public as regional warnings from the National Weather Service. REPETITIVE LOSS PROPERTIES Of primary concern to the City of Friendswood are the four major watersheds: Clear Creek, Chigger Creek, Cowards Creek and Mary's Creek. Several smaller drainage features also crisscross the city's 21.1 square miles. FEMA DEFINITION The Flood Mitigation Assistance (FMA) Grant Program provides grants to assist states and communities in implementing measures to reduce or eliminate the long-term risk of flood damage to buildings, manufactured homes, and other structures insurable under the NFIP. The FMA Grant Program was created as part of the National Flood Insurance Reform Act (NFIRA) of 1994 with the goal of reducing or eliminating claims under the NFIP. The Biggert-Waters Flood Insurance Reform Act of 2012 changed the FMA Grant Program in 2013 to allow more federal funds for properties with repetitive flood claims and 26 HAZARD MITIGATION PLAN - City of Friendswood severe repetitive loss properties, and the Repetitive Flood Claims and Severe Repetitive Loss Grant Programs were eliminated. Repetitive Loss (RL) and Severe Repetitive Loss (SRL) data is based on flood insurance damage claims by property and by community. SRL An SRL property is defined as a residential property that is covered under an NFIP flood insurance policy and: That has at least four NFIP claim payments (including building and contents) over $5,000 each, and the cumulative amount of such claims payments exceeds $20,000; or • For which at least two separate claims payments (building payments only) have been made with the cumulative amount of the building portion of such claims exceeding the market value of the building. • For both of the criteria detailed above, at least two of the referenced claims must have occurred within any ten-year period, and must be greater than 10 days apart. RL Any residence or business that has received two or more claim payments greater than $1,000 from the National Flood Insurance Program within any rolling 10-year period, the property is considered a Repetitive Loss (RL) structure. Repetitive flood loss data for the city reveals 307 residences with a history of severe and/or repetitive flood losses. The buyout process following Tropical Storm Allison (2001) mitigated (removed) 112 properties from the RL/SRL inventory, leaving a total of 195 properties remaining on the repetitive flood loss listing. In July 2011, Galveston County participated in the FEMA SRL Elevation grant Program. This is a voluntary mitigation program to provide funding to reduce or eliminate long-term risk of flood damage to SRL and RL structures insured under NFIP. The SRL Elevation Project criteria are to raise existing structures at or above the BFE (base flood elevation), must be cost-effective and prior flood loss determines benefit. This program was extended to homeowners in Friendswood, Galveston County, for participation. Friendswood has 14 RL/SRL participating properties. Once all the elevations have been completed, there will be a remainder of 181 RL/SRL properties in Friendswood. The 181 unmitigated RL/SRL properties represent .1.56% of the 11,583 households within the city. FEMA Community Information System records indicate the city has 7,380 flood insurance policies in force with coverage totaling $2,245,449,000 and $3,273,504 in paid premiums. The city has reviewed FEMA records to determine which areas of the city have received flood insurance claims. Based upon FEMA Community Information System records 1,175 flood claims have been paid with losses totaling $48,644,765 (includes structure and contents losses). The average residential flood insurance claim paid in the city is $49,340. There are 7,380 flood insurance policies in force within the city, which represents 55% of the total structures. Historically, flood events that have occurred within the city were the direct result of flash and riverine flooding. All of the significant flood events were precipitated by heavy rain events. Hurricane Ike, September 2008, produced significant tidal surge heights; however, only one (1) incident of flooding was documented within the city. The rising water did not inundate the living quarters of the residence, but the garage area only. 27 HAZARD MITIGATION PLAN - City ofF/%endswood TABLE 7 SU MMARY OF RL AND SRL PROPERTY CLAIMS RL/SRL MITIGATED ALL RECORDS PROPERTIES Total Number of Properties 307 112 Number of Paid Claims 1,175 532 Building Payments $32,585,977 $19,560,601 Contents Payments $16,058,788 $10,743,528 TOTAL PAYMENTS $1§,644,765 $30,304,130 Average Payment $28,524 $56,963 Building Value $43,358,874 $19,442,020 PERCENTAGE MITIGATED AS OF 04/30/2014 36.48% TABLE 8 GALVESTON COUNTY 2013 HMA GRANT ASSISTANCE PROGRAM/ELEVATION 2013 HMA GRANT ASSISTANCE PROGRAM Total Number of Properties 14 Number of Paid Claims 65 Building Payments $1,964,463 Contents Payments $923,919 TOTAL PAYMENTS $2,888,381 Average Payment $44,437 Building Value $2,525,109 TOTAL PERCENTAGE MITIGATED 112 BUYOUTS t 14 ELEVATED 41% Of the 14 property owners who have executed contracts through the 2013 HMA Grant Assistance program through Galveston County, participation was voluntary.

Prior to 2008, of the 7 major flooding events 6 were federally declared disaster events. Since 2008, three (3) flooding events have affected the city. Heavy rainfall occurred April 18-19, and again on April 24, 2009. Widespread street flooding occurred due to overwhelmed drainage systems. One report of residential flooding occurred with approximately $5,000 in damages. Hurricane Ike was a severe wind event with extensive debris in the form of downed trees and fences; however, one flood report was received regarding flooding in a detached garage. EXTENT Drainage systems within the city are constructed to handle the runoff of 2"of rain per hour. With this design, rain is expected to remain in the streets and prevent flooding of homes and other structures. However, whenever rainfalls which exceed the 2" per hour, the existing storm drainage system can become overwhelmed and result in street flooding which makes some roads impassable, and also cause water to rise into the yard areas of the structures. The Office of Emergency Management maintains a listing of all the streets located near Clear Creek, Chigger Creek, Mary's Creek, and Cowart Creek where water levels may cause the streets to become impassable during rain events when over 2" off rain falls within an hour or longer. During storm events where rainfall exceeds 2" per hour, members of the Friendswood Police Department and the Office of Emergency Management survey the status of all streets on the list. Currently there are 63 city blocks that are monitored during such rain events. In the event streets become impassable, the Public Works Department will place barriers to prevent motorists driving through the area. The city also monitors all Harris County Flood Control District flood gauges in Clear Creek when during heavy rain events and when runoff is expected from bayous in Houston and Harris County. When rainfall and/or storm runoff exceeds the 2" per hour rate, flooding along the four watersheds will flow over their banks and threaten structures and roads will become impassable. With flooding along the designated flood zones as indicated on the map in FIGURE 4, it is estimated that approximately 1.56% of the houses within the city are vulnerable (181 homes) to potential flooding from a level of a few inches to several feet. Depth of flooding varies depending on the location of the residence; i.e., located in a floodway or a 100-year flood zone. Several flood mitigation projects completed by the city and projects completed in cooperation with the Galveston County Consolidated Drainage District have alleviated flooding problems in several areas of the city. Completion of the following drainage projects as identified in the city's capital improvements plan has reduced flooding in the following areas: DRAINAGE PROJECT NUMBEROF DETENTION RESIDENCES AFFECTED ACREAGE Sunmeadow 504 Annalea/Whitehall/Kin s Park 516 Clover Acres 23 Glenshannon 142 Woodlawn 17 FM518 Willowick to Cowards Creek 71 West Ranch 1141 54.7 All new commercial development within the city is required to provide detention/retention ponds on site. Residential developments are required to provide detention/retention areas, or open space areas which allows water along the creeks to spread out during flood events thus slowing the flow of the water, and prevents water from encroaching onto residential or commercial properties. 33 HAZARD MITIGATION PLAN - City OPF/%endswood TABLE 10 FLOODING EVENTS 2008-2013 DATE EVENT DESCRIPTION ESTIMATED DAMAGE COSTS Total rainfall for both days was 8"; of which 6"fell in a one hour time period around Clear Creek at FM 528. Tides were elevated due to April 18-19, 2009 persistent easterly and southeasterly winds, which resulted in slower Unknown Heavy Rainfall than normal drainage in low lying coastal areas near Clear Lake and None Reported Galveston Bay. Widespread street flooding occurred mainly from drainage systems being overwhelmed by the intense rainfall. Flash Flood from a series of thunderstorms which produced heavy rainfall and strong winds across portions of Harris, Galveston and April 24, 2009 Chambers Counties. Numerous roads in and around Friendswood were Heavy Rainfall impassable due to high water caused by heavy rainfall. Several high $5,000 water rescues were required due to the flooding. Total rainfall was 6"; two house fires occurred as a result of lightning strikes. One home was flooded in the SE portion of the city. 34 IGGAU) mm6Fnon PLAN — GTyOfRle dSWOod FIGURE 4 ROOUPLMN MAP 1 A B C D E F G H I ] K L 1 2 — ®� 2 4 --_ 4 5 g^ 5 6 p4<. 4` _ 6 8 ill ..r 8 9 u \ B 12 12 13 � yy `'�r�0 �N ��f� !� 13 a ei , 14 � \-i \� 14 16 , 'a/ �� / 16 17 �J � � � � C � C � 17 18 18 E 19 rl I �', _ � �s 19 tt�E{`.SEC` Sii F[1EF 21 22 �ir5' 20� \\. �i:rri�== eF4F 22 23 A B C D E F G H I ] K L 23 HAZARD POPULATION PLAN — PLED nrRle7eswone HARRIS COUNTY FLOOD CONTROL CONTRACT Afar devastating floods of 1929 and 1935, He City of Houston issued a plea to Congress and secured a commitment for Federal flood cuno-ol assistance In 1937, the Texas Legislature created the Han is County Flood Centel Dist PC and designated He Harris County Commissioner's Court as the governing body.

The system relies on 133 gage stations strategically placed throughout Harris County bayous and their tributaries. The stations contain sensors that transmit valuable data during times of heavy rainfall and during tropical storms and hurricanes. Some gages also measure wind speed and direction, barometric pressure, air temperature, road temperature and humidity. The purpose of the Flood Warning System website is to provide information collected by the gages in a user-friendly format. This ��•'�'•=°-"'- a information is used to inform of imminent and current flooding - -• conditions along bayous. It also is _ used by the National Weather Service to assist in the issuing of flood watches and warnings.

The FIS indicates that riverine flooding results primarily from overflow of the streams and drainage ditches caused by rainfall runoff, ponding, and sheet flow. Storms occurring during the summer months are often associated with tropical storms moving inland from the Gulf of Mexico. Thunderstorms are common throughout the spring, summer and fall months. Hurricanes and tropical storms interrupt the summer with high winds, heavy rainfall, and high storm surges. COF DRAINAGE PROJECTS The city continues to enforce its floodplain management ordinance and retain a CRS Rating of 5. Despite efforts to improve our Rating to that of a 4, changes by FEMA to the CRS Manual and grading criteria have made pursuit of a CRS Rating of 4 much costlier. The city maintains $1,000,000 of General Reserve Funds to put toward the Mud Gully drainage and detention project. This project is a major component of the USACE's overall Clear Creek project. Design of the Mud Gully improvements is well underway with Phase 1 expected to break ground in early 2014.

The city continues to maintain listing of those properties to ensure compliance with our floodplain management ordinance. Through an HMA Grant for SRL/RL properties, 14 homeowners have executed contracts to participate in a voluntary elevation mitigation project. This project will elevate these 14 residences above the BFE (base flood elevation). This program is a 90/10% cost share program coordinated through Galveston County. FLOODPLAIN MANAGEMENT PLANNING The Community Rating System (CRS) is an overall strategy of programs, projects, and measures that will reduce the adverse impact of a flood hazard on the community. The CRS does not specify what activities a plan must recommend, but recognizes plans that have been prepared according the standard planning process. Emphasis is based on Floodplain Management Planning (FMP), Repetitive Loss Area Analyses (RLAA), and Natural floodplain functions plan (NFP). Since the city is classified as a Category C repetitive loss community, it must prepare either a FPM or RLAA area analysis that covers at least all of its repetitive loss areas. GALVESTON COUNTY CONSOLIDATED DRAINAGE DISTRICT- PROJECTS/EXTENT OF SERVICES PROVIDED The District's mission remains the same: to reduce the probability of flooding throughout the Friendswood area by improving drainage while preserving the natural beauty of the creeks, resulting in increased safety, higher quality of life and an environment fostering economic growth. 41 HAZARD MITIGATION PLAN — City ofF/%endswood COMPLETED PROJECTS Wegner Ditch/Tributary 2 —City of Friendswood and GCCDD Replace ditch with box culvert and shallow surface Swale; will improve drainage and reduce long term maintenance using inline detention and the Baker Road detention facility Channel improvements to Chigger Creek Conservation and reclamation of existing drainage channel using inline detention Phase 1 — Slope Improvements from Clear Creek to Oak Drive Phase 2 — Slope Improvements from Oak Drive to FM518 Phase 3 — Slope Improvements from FM518 to FM528 BIGGERT-WATERS (BW-12) FLOOD INSURANCE REFORM ACT OF 2012 The Biggert-Waters Flood Insurance Reform Act of 2012 (BW-12) was passed by the U.S. Congress in hopes of making the NFIP more financially stable by raising rates on certain properties to reflect the true cost of flood risk. FEMA is also in the process of updating all FIRM (Flood Insurance Rate Maps) maps usually adopted by those communities participating in the NFIP program. The BW-12 Act hopes to achieve that insurance rates will more accurately reflect the flood risk. The BW-12 will phase out subsidized rates for non-primary/secondary residences, along with eliminating the subsidized rates for certain other classes of properties. Although only twenty percent (20%) of NFIP policies receive subsidies, rates will increase at a 25% annual rate for non-primary/secondary residences in a SFHA(begins January 1, 2013), subsidized policies on property that has experienced severe or repeated flooding until rates reflect true risk(begins October 1, 2013), and subsidized policies on business/non-residential properties in a SFHA until rates reflect true flood risk(October 1, 2013). Along with policy rate increases, property owners may have to obtain an elevation certificate to determine correct rates. Along with premium increases, policy holders will also be paying a 5% Reserve Fund Assessment' on the policy premium. This assessment will be used to create a reserve fund to reduce the NFIP's need to borrow money from the federal government to pay claims. There will also be an annual Federal Policy Fee'of $44.00 on each policy to cover the operational cost of the program. The ICC (Increased Cost of Compliance) fee of$34.00 provides policyholders who need extra funds to bring their property into compliance with local floodplain ordinances after it is damaged by a flood. The coverage provides up to $30,000 to elevate, relocate, flood-proof or demolish the property. 42 HAZARD MITIGATION PLAN - City ofF/%endswood 2009 MITIGATION ACTION ITEMS FLOODPLAIN MANAGEMENT COMMUNITY RATING SYSTEM RECERTIFICATION • Review and update the city's floodplain The city continues to enforce its floodplain regulations/ordinances as appropriate. management ordinance (City of Friendswood, • Review and update the city's Regional Drainage Code of Ordinances, Part II, Chapter 34-Floods) Study. for all development in order to maintain the • Coordinate and cooperate with USACE and current CRS rating of 5.

The latest hurricane/tropical storm to affect the city was Hurricane Ike, September 12- 14, 2008. Hurricane Ike made landfall on September 13, 2008, over Galveston as Sept. 13, 2008 a large Category 2 hurricane. An estimated 37 people lost their lives as a result of Hurricane Ike. Although Friendswood received only $21.3 FEMA 1791-DR-TX received one unverified report of flooding in a detached garage, Billion HURRICANE IKE damages within the city were primarily wind caused with extensive debris removal required from downed trees and fences. Most notable historical tropical events which have affected Friendswood are Hurricane Carla (06/11/1961), Hurricane Alicia (08/15-18/1983), Hurricane Rita (09/21/2005), and Hurricane Ike (09/13/2008). Time spans between Hurricane Carla and Alicia is 22 years; between Alicia and Rita is 22 years, and between Ike and Rita is 3 years. 46 HAZARD MITIGATION PLAN - City of Friendswood HURRICANE CARLA- 1961 • Land fall in the area of Port O'Connor • High winds for an extended period of time (100 mph) • Storm surge in west Galveston Bay of 14-16 feet • Rain amounts of 5-10"on east of the eyewall • No storm surge affected the City of Friendswood • Extensive wind damage to outbuildings, built environment, and vegetation ALICIA—1983 • Third depression, lit tropical storm, and only hurricane of the Atlantic season (small Category 3) • Traveled up IH-45 from Galveston to Houston • Spawned 23 tornadoes (14 in Galveston/Hobby Airport area) • Rainfall amounts of 10-11' • Structures damages/destroyed: 2,297 destroyed, 30,000 major damage, over 10,000 minor damage • Friendswood experienced extensive structural and vegetative debris HURRICANE RITA-2005 • Landfall in the Matagorda Bay area • Galveston &Harris County ordered an evacuation • Major gridlock on evacuation routes from coastal areas to Dallas and San Antonio • Traffic congestion, lack of fuel, extreme heat, lack of access to food and water, and comfort stations led to discomfort and health problems for some. HURRICANE I KE-2008 • Diameter of storm was 425 miles • Moved NNW, and east of IH-45 • 110 mph winds • Storm surge was in upper SE coast • Longevity of the storm over SE Texas contributed to extensive wind damage, not the intensity of the winds • Tornadoes occurred in Liberty County on 9/13, 12-15 hours after landfall • No storm surge experienced in Friendswood • Friendswood experienced extensive vegetative debris In addition to the 20 hurricanes over the past 110 years, Galveston County has also experienced numerous tropical storms. Results of the NCDC query shows that Harris and Galveston Counties have been impacted by 6 tropical storms between 1950 and 2008. The most significant tropical storm to affect the area was Tropical Storm Allison in June 2001. This storm was a major rain and flooding event, with minor damages from high winds. The surrounding area received up to 35 inches of rain over a period of five days. With a total of 30 tropical storms between 1900 and 2008, Galveston and Harris Counties experience a tropical storm on average about slightly less than every 4 years. This equates to a 27% annual probability of a future tropical storm event occurring in Galveston and Harris Counties. Based on the high, medium and low ranges identified in Table 16, there is a high probability of future tropical storms occurring in both counties. The Table is based on data queried from the National Hurricane Center's Hurricane and Tropical Storm Tracker between 1900 and 2008. There is only a 4% annual probability for a major hurricane while a tropical storm has a 27% annual probability. Numerous factors affect the development of tropical systems, making annual predictions difficult at best. History shows that the city is not affected by a tropical storm and/or hurricane each and every year, however, the potential still exists. During hurricane season (June 1 through November 30)the Office of Emergency Management is in a heightened stage of awareness and preparedness. Regardless of the time span between hurricanes which may or may not affect the city, hurricane preparedness is a major priority for the OEM.

Based on high, medium, and low probability ranges in the hurricane probability is considered medium for Category 1 and 2 magnitude storms, and low for Category 3 and higher. (Tropical Meteorology Research Project,Colorado State University&GeoGraphics Laboratory,Bridgewater state University) Map a in Figure 8 shows the return period for all hurricanes (categories 1-5) in Galveston County at 5.4 years, which equates to an approximate 20% annual probability of future occurrences. Major hurricanes (Map c) have occurred every 19.4 years in Galveston County, which translates to an approximate 6% annual pro ba bII Ity. (Hurricanes of the North Atlantic, Climate and Society,James Elsner and A. Birol Kara,New York, Oxford University Press,1999) Based on high, medium, and low probability ranges, the hurricane probability is considered medium for Category 1 and 2 magnitude storms, and low for Category 3 and higher (Table 16). As mentioned earlier, future probability is only one component of the risk calculation. Although the hurricane hazard is considered to have a medium to low probability, a hurricane (particularly a major hurricane) has potential for catastrophic impacts on life and property in the planning area. Potential impacts are high for all hurricane categories. sI HAP M MIUGAUOX PLM — myOfrll eswooe 0 52 HAZARD MITIGATION PLAN - City ofF/%endswood STORM SURGE From 1971 until 2008, the NHC used the Saffir-Simpson Hurricane Scale, which also utilized pressure, storm surge and flooding measurements. After Hurricane Ike in 2008, which produced a storm surge undeserving to its Category 2 status, the NHC dropped all requirements except wind "to help reduce public confusion about the impacts associated with the various hurricane categories as well as to provide a more scientifically defensible scale." However, the National Hurricane Center does believe that storm surge scales would be helpful or effective at conveying the storm surge threat. As an example, if Hurricane Ike had made landfall in Palm Beach, Florida, the resulting storm surge would have only been 8', rather than the 20'that occurred where Ike actually made landfall on the upper Texas coast. These greatly differing surge impacts arise from differences in the local bathymetry (the shallow waters off of Texas enhance storm surge while the deep ocean depths off of southeastern Florida inhibit surge). The proposed storm surge scales that consider storm size do not consider these local factors that play a crucial role in determining actual surge impacts. Potentially disastrous surges occur along coasts with low-lying terrain that allows inland inundation, or across inland water bodies such as bays, estuaries, lakes and rivers. For riverine situations, the surge is sea water moving up the river. The storm surge depends greatly upon the size and intensity of a hurricane, the angle that it approaches the shore at, how deep the water is close to shore (the slope of the seabed at the coastline), and how fast the hurricane is moving. There are several factors that contribute to the amount of surge produced by storms at any given location: • Central Pressure • Storm Intensity • Storm Forward Speed • Angle of Approach to Coast • Shape of the Coastline • Width and Slope of the Ocean Bottom • Local Features As can be seen in the following maps, the majority of ground elevation in the Clear Creek Watershed in Friendswood lies within the 25-30 foot range. The Hurricane Surge Map located in FIGURE 11 indicates areas of the city with flooding potential from storm surges greater than twenty feet (20'), previously designated as classification of a Category 4 or 5 hurricanes. A storm surge of thirty feet (30') or greater could affect approximately twenty-five to forty- five percent (25%-45%) of the city. Either one of the above scenarios could inundate the area with salt water. Several critical facilities including schools, city facilities, day cares and senior care facilities may be affected by either of those levels of storm surge. Any rainfall will be exacerbated by a surge of twenty feet (20') or more, resulting in flooding. A surge of any level coupled with heavy rain would also produce flooding. Excessive rainfall amounts, which normally drain into the Clear Creek watershed, will increase the level of water accumulation due to the inability for drainage into Galveston Bay via Clear Creek. As noted earlier, size, forward speed, and landfall location of the hurricane eye will affect the amount of inundation from a storm surge. Hurricane Ike, September 2008, was classified as a Category 2 hurricane, with little or no rainfall, and made landfall between Galveston Island and the Bolivar Peninsula. The greatest amount of storm surge was across Bolivar Peninsula at twenty feet (20'); however, the surge level near Kemah at the entrance of Clear Lake was recorded at a level of ten to twelve feet (10- 12'). Therefore, the city was not affected by storm surge during Hurricane Ike, and the major damages were due to wind. 53 HAZARD MITIGATION PLAN - City ofF/%endswood A major planning factor for surge potential would be if a hurricane makes landfall west of Galveston Island, causing the greatest force of the hurricane to traverse over Galveston Island and inland, and also increasing the surge level in Galveston Bay. SEA,LAKE,AND OVERLAND SURGES FROM HURRICANES(SLOSH) The SLOSH (Sea, Lake, and Overland Surges from Hurricanes) model is the computer model developed by the National Weather Service for coastal inundation risk assessment and the prediction of storm surge. It estimates storm surge heights resulting from historical, hypothetical, or predicted hurricanes. SLOSH computes storm surge by taking into account a storm's atmospheric pressure, size, forward speed, track, and winds. The calculations are applied to a specific locale's shoreline, incorporating the unique bay and river configurations, water depths, bridges, roads, levees, and other features. The Operational Storm Surge Basins for SLOSH model accounts for astronomical tides (which can add significantly to the water height) by specifying a constant tide level to coincide with landfall, but does not include rainfall amounts, river flow, or wind-driven waves (those riding on top of the surge). The SLOSH model is the basis for the "hazard analysis" portion of coastal hurricane evacuation plans. However, the SLOSH model does not explicitly model the impacts of waves on top of the surge; it does not account for normal river flow or rain flooding; nor does it explicitly model the astronomical tide (although operational runs can be made with different initial water level anomalies). Future advancements in the SLOSH model will allow for the resolution of some of these limitations. SLOSH DISPLAY PROGRAM AIDS IN EVACUATION PLANNING The SLOSH Display Program is software developed as a tool to aid emergency managers in visualizing storm surge vulnerability. The SLOSH model and the display program are two different tools. The National Weather Service uses the SLOSH model to forecast storm surge and model storm surge vulnerability; emergency managers and others use the display program to visualize the SLOSH data. Graphical output from the model shows color-coded storm surge heights for a particular area in either feet above ground level (inundation) or feet above a specific reference level. The SLOSH Display Program displays the results of the SLOSH model in order to assist emergency managers planning for evacuations and to educate decision-makers. PROBABILISTIC HURRICANE STORM SURGE(P-SURGE) Numerical storm surge models depend on an accurate forecast of the hurricane's track, intensity, and size. Even the best hurricane forecasts still have considerable uncertainty. The National Hurricane Center's forecast landfall location, for example, can be in error by tens of miles even during the final 12 to 24 hours before the hurricane center reaches the coast. These limitations can make the single, deterministic SLOSH surge forecasts incorrect. To help overcome these limitations, forecasters use probabilistic storm surge (P-surge) forecasts. The Probabilistic Hurricane Storm Surge (P-Surge) model predicts the likelihood of various storm surge heights above a datum or above ground level based on an ensemble of SLOSH model runs using the official hurricane advisory. Graphical output shows: • storm surge heights which have a certain probability of being exceeded • the probability of storm surge exceeding a certain height These storm surge heights and probabilities are based on the historical accuracy of hurricane track and wind speed forecasts, and an estimate of storm size. P-Surge also computes the probability of surge above ground to more clearly communicate where the surge will occur. 54 HAZARD MITIGATION RAN- City ofFriendswood A sample output of the SLOSH model can be seen here for Hurricane Ike. t'hF• 6 •�� ., Approximate location of the City of Friendswood T: } l Y _i Storm damage from Tropical Storm Allison—June 3001 55 HAZARD mmGFnon PLAN — GTyOfRle dSWOOd FIGURE 10 COASTAL GROUND ELEVAnons HIGGS CVO GALVESTON COUNTIES Hams County Coastal Ground Elevations 'B0� ��"°��.

Tropical Storm Edouard moved ashore between High Island and Sabine Pass producing minimal damage of$100,000, and caused tidal flooding on portions of Bolivar Peninsula with damages reported at $95,000. The second event to cause storm surge flooding was Hurricane Ike which made landfall near Galveston September 12-13, 2008. Storm tidal surge ranged between 10-13 feet on most of Galveston Island and Galveston Bay. Approximately 37 deaths, directly or indirectly, were attributed to Hurricane Ike. One report of flood damage was made in Friendswood to a detached garage near Clear Creek; however, no other reports of flooding occurred within the city occurred. EXTENT The City of Friendswood sits on land approximately 10'to 35'feet above sea level, with the largest portion of the city located on land approximately 25-30'above sea level. The National Hurricane Center provides two near worst case scenario planning products based on hypothetical storm tracks: Maximum Envelopes of Water (MEOWs) and Maximum of Maximums (MOMs). MEOWs are created by computing the maximum storm surge resulting from roughly 10,000 to 60,000 hypothetical storms simulated through each SLOSH grid of varying forward speed, radius of maximum wind, intensity(Categories 1-5), landfall location, initial water level, and storm direction. A MEOW product is created for each combination of category, forward speed, storm direction, and initial water level. SLOSH products do not include Category 5 storms north of the NCNA border. For each storm combination, parallel storms make landfall in 5 to 10 mile increments along the coast within the SLOSH grid, and the maximum storm surge footprint from each simulation is composited, retaining the maximum height of storm surge in a given basin grid cell. No single hurricane will produce the regional flooding depicted in the MEOWs. SLOSH model MOMs are an ensemble product of maximum storm surge heights. MOMs are created for each SLOSH basin by compositing all the MEOWs, separated by category and initial water level, and selecting maximum storm surge value for each grid cell regardless of the forward speed, storm trajectory, or landfall location. MOMs represent the worst case scenario for a given category of storm and initial water level under ideal storm conditions. Here, a high tide initial water level is used in the analysis. The following graphic depicts the worst case $ scenario for Friendswood \ based upon the MOMs as defined in the preceding P' paragraph. Using this e scenario, a majority of the city would be inundated with water ranging from 3 feet above ground to greater than 9 feet above } ' ground. — �IL z „I� " P`'••,, i�i�if� iii s` 6 &OIL, %ii�✓ �ii iii%�l�/ Historically, the city has not experienced storm surge from previous events, and would not expect this type of storm surge in future hurricanes. 58 HAZARD MITIGATION PLAN - City of Friendswood PROBABILITY FREQUENCY OF OCCURRENCE ❑ Highly Likely Event probably in next year ❑ Likely Event probable in next 3 years ■ Occasional Event possible in next 5 years ❑ Unlikely Event possible in next 10 years TABLE 11 below shows those critical facilities within the city which have the potential of being affected by storm surge, storm surge exacerbated with rainfall, or excessive rainfall.

The Emergency Management Office works diligently to increase preparedness and improve mitigation efforts related to hurricanes and tropical storm events. The Focus ofFriendswood Newsletter devotes considerable space in the Spring and Summer issues providing hurricane safety and preparedness information. Emergency Management officials supply the bulk of materials featured in the newsletter. The Emergency Management Office staff also conducts several presentations throughout the year to help increase citizen awareness and preparedness for hurricanes, tropical storms, and other hazardous conditions. These presentations focus on property protection and protection of life. Included in the educational presentations and materials is the Hurricane Evacuation Zip-Zone for the coastal areas of southeast Texas developed by the Houston-Galveston Area Council. Following Hurricane Ike, September 2008, the Hurricane Evacuation Zip-Zone map was amended to reflect the north and south portions of zip code 77546, which encompasses the City of Friendswood. The north portion of the 77546 zip zone is located in the unincorporated area of Harris County. When an evacuation order was issued by the Harris County Judge prior to landfall of the hurricane, residents of Friendswood were under the assumption that the city was included in that evacuation order, although the Mayor of Friendswood had not issued such an order. Although residents of the north 77546 zip zone have Friendswood mailing addresses, they do not reside within the corporate limits of the City of Friendswood. (SEE FIGURE 12) The city participates in a variety of exercises and disaster drills both locally and regionally to help increase preparedness. Disaster exercises and drills are a vital function of the emergency management program. Routine emergency drills and disaster exercises allow for city officials to interact with other local jurisdictions, regional emergency service providers, as well as state and federal agencies. Exercises assist to identify potential problems or weaknesses in emergency management activities, as well as identify strengths and strategic alliances between departments, organizations, and outside agencies. 60 HAZARD mm6Fnon PLAN — GTyOfRle dSWOOd FIGURE 12 HURRICANE EVALUATION ZIP-ZONES Q '. € e EL E ZE P gg2 $ u gg p l aii. ? ww ed All m0 i` �' e @ @€ E p p N LP 1 • J p 1 EE HAZARD MITIGATION PLAN - City of Friendswood 2009 MITIGATION ACTION ITEMS CRITICAL FACILITIES PROTECTION • Stationary generators were installed at all lift stations and surface water stations which were not located in a designated flood zone.

The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. Tornadoes come in many shapes and sizes, but are usually in the form of a visible condensation funnel,and when narrow end touches ground it is often encircled by a cloud of debris and dust. According to Hie National Weather Service, tornado wind speeds range from 40 to more Hian 300 miles per hour. The most violent tornadoes have rotating winds of 250 mph or more and are capable of causing extreme destruction. Tornadoes are related to larger vortex formations, and therefore often form in convective cells such as thunderstorms or in the right forward quadrant of a hurricane, far from the hurricane eye.

The scale has the same basic design as the original Fujita Scale (implemented in 1971) with six categories from zero to five representing increasing degrees of damage. The Enhanced Fujita Scale includes 28 damage indicators categorized by building type and construction. According to NOAH, the Enhanced Fujita Scale is a set of wind estimates (not measurements) based on damage on a judgment of 6 levels of damage. The new scale takes into account the quality of construction and standardizes different types of structures. None of the tornadoes recorded on or before January 31, 2007, will be re-categorized. For detailed information on the Enhanced Fujita Scale and damage indicators, please see htto://www.si)c.noaa.gov/fao/tornado/ef-scale.htmi. PREVIOUS EVENTS During the period of 1950-2015, the National Weather Service recorded 2 tornadic events in the vicinity of Friendswood. Of these 2 tornadoes, 1 was categorized as EFO and 1 was categorized as an EF1. Total damage for these events was reported to be $520,000. These tornadoes were approximately .2-.3 miles in length and 20-50 yards in width. Records from the NCDC, show no reported tornado sightings and/or touchdowns within the city since 2008. LOCATION AND EXTENT LOCATION Tornadoes can result from severe thunderstorm activity, or may occur during a major tropical storm or hurricane. Based upon historical data, tornado activity was recorded in a 65 year period of .004%. Because it cannot be predicted where a tornado may strike, all buildings and facilities are considered to be exposed and could potentially be impacted. As noted in the table at the beginning of this section, vulnerability estimate for damages is $2,973,017,641. Damages will be variable and are dependent upon the location of touchdown in specific sections of the city. EXTENT Based upon the premise that the entire city is vulnerable to a tornadic event, if an EFO or EF1 were to occur within the city, damages for debris could range up to 500,000 cubic yards of woody debris and construction &demolition debris. Debris removal expenses could reach into the $7-10 million dollar range. As stated above, total structural damages could reach $2,973,017,641 and does not include estimates for contents of all structures. Based upon historical occurrences, the city does not anticipate experiencing tornadoes stronger than an EFO or EF1; however, the city is aware that a stronger tornado could potentially affect the area at any time in the future. Due to the infrequency and minimal intensity of previous tornadic events, the city does not require tornado safe rooms to be constructed within new and/or remodeled residential, commercial or school facilities. However, building construction strength standards increase with each new edition of the IBC; i.e., structures are currently required to be built to withstand 120 mph winds. PROBABILITY FREQUENCYOF OCCURRENCE ❑ Highly Likely Event probably in next year ❑ Likely Event probable in next 3 years ❑ Occasional Event possible in next 5 years ■ Unlikely Event possible in next 10 years MITIGATION STRATEGY Due to the infrequency of tornado activity within the vicinity of the city, the primary preparedness strategy is public awareness and education. 64 HAZARD MITIGATION PLAN - City of Friendswood 2009 MITIGATION ACTION ITEMS SHELTER-IN-PLACE PUBLIC EDUCATION CAMPAIGN • Design/develop a public awareness flyer for shelter-in-place procedures • Schedule presentations with all critical and vulnerable facilities within the city • Distribute the flyer to all residents within the city • Provide detail listing of all residential, critical and/or vulnerable facilities within each evacuation zone for all pipeline corridors as outlined in the Pipeline Map (Appendix E) and ensure these zones are designated for the First Call Notification System Ongoing Review and update the program on an annual basis • Conduct presentations for the public at the Friendswood Public Library, Mayor and City Council members • Post the flyer on the City of Friendswood's website and Friendswood PEG Channel 17 • Pre-record messages for broadcast over Friendswood Information Radio 1650 AM CRITICAL FACILITIES PROTECTION AUXILIARY POWER COMPLETED WITH HAZARD • Fire Station #1 MITIGATION GRANT FUNDING • Fire Station #2 • Fire Station #3 ALL CITY CRITICAL FACILITIES ARE NOW • City Hall EQUIPPED WITH BACK-UP AUXILIARY POWER • Library • Ensure continuous operations of the city's critical Funding has been received for a manual facilities. transfer switch installation for the Public • Will allow for continuity of government, ensure Works Facility with Homeland Security continued communications during times of power Grant funding. outages and/or disastrous events, and assist with response and recovery operations. • Equipping the Fire Stations with generators will assist the community with communications, search and rescue operations. • The Activity Building was equipped with full back- up power coverage in December 2002. • City Hall (constructed in 1995/96) back-up power for the mainframe computer system, telephones, certain electrical outlets and emergency lighting was included. • Public Safety Building is equipped with full back-up power coverage. • Fire Station #4 auxiliary power supply was included with construction plans for the facility with CIP funding. 65 HAP M MIUGAUOX PLM — myOfrll eswooe Mi HAZA RD MILIGAVITION PLAN spin A fronoweed DROUGHT brought is offen thought oF as a codes ion oF climatic dryness that is F severe enough to reduce soil masture and water supplies below the requireareeks necessary to ell sustain normal deny animal, and human Fas Drought can also be backed 'as the consequence 4 a natural He ddion in the amount oF precipitation expeded over an me extended period 4 time, usually a STAGE A season or more in graph term can be unher dind agicultural and bespoke earcultual drought is a by period oF sul Anatior and intensity that asp and animal agnaulture are markedy affected Heardody bought is a kanyl condition oF abnormally dry weather that ultimately leads to the decision oF surnace and ground water supplies Durgy hydrologic drought, a significaff reduction in the Flow 4 ravers, streams, and springs is noticed 4 will AGGNNl PREVIOUS Fail&EXTENT PREVIOUS Fail Wthin the past Fee was (2008 2013) no extended pences oF drought have been recorded per His crowded by the Al Fix signpost Gavestion County, or Harris County in southeast Texas edhough the area is vulnerable to duct estimated losses are pride difficult to calculate because di damage to the bull entmenament is difficult to track Therecone, it is assumed that all buil ones and Facilities are expesed to bought and cand experience Foundation A structural L damage 67 NF]ARO mm6Fnon PLAN — OFF OrRAc,esi EXTENT The entire planning area may be attacked by drought as no one portion Is more at risk than any other part of the area Rlanaswooa is located in the Upper Coast Climactic division.

The Palmer Index is most effective in determining long term drought. The Advantage of the Palmer Index is that it is standardized to local climate, therefore can be applied to any part of the country to demonstrate relative drought or rainfall conditions. This Index is not as good for short term forecasts. PALMER Z INDEX • Measures short-term drought on a monthly scale CROP MOISTURE INDEX(CMI) • Measures short-term drought on a weekly scale to quantify a drought's impacts on agriculture during the growing season PALMER DROUGHT SEVERITY INDEX(PDSI) • Attempts to measure the duration and intensity of the long-term drought-inducing circulation patterns. • Long-term drought is cumulative, so the intensity of drought during the current month is dependent on the current weather patterns plus the cumulative patterns of previous months. PALMER HYDROLOGICAL DROUGHT INDEX(PHDI) • Developed to quantify hydrological effects and is a long-term drought index; responds more slowly to changing conditions than the PDSI STANDARDIZED PRECIPITATION INDEX • A probability index that considers only precipitation. The SPI is an index based on the probability of recording a given amount of precipitation, and the probabilities are standardized so that an index of zero (0) indicates the median precipitation amount. This index is negative for drought and positive for wet conditions. The SPI is computed by NCDC for several time scales, ranging from one month to 24 months, capturing various scales of both short-term and long-term drought. The objective of the Palmer Drought Severity Index(PDSI) provides measurements of moisture conditions that are standardized so comparisons using the index can be made between locations and between months. The PDSI is a meteorological drought index, and it responds to weather conditions that have been abnormally dry or abnormally wet. Palmer developed the PDSI to include the duration of a drought (or wet spell). His motivation was as follows: an abnormally wet month in the middle of a long- term drought should not have a major impact on the index, or a series of months with near-normal precipitation following a serious drought does not mean that the drought is over. Therefore, Palmer developed criteria for determining when a drought or a wet spell begins and ends, which adjust the PDSI accordingly. The Palmer Index is popular and has been widely used for a variety of applications across the United States. It is most effective measuring impacts sensitive to soil moisture conditions, such as agriculture. It has also been useful as a drought monitoring tool and has been used to trigger actions associated with drought contingency plans. Three positive characteristics of the Palmer Index provide decision makers with a measurement of the abnormality of recent weather for a region; provides an opportunity to place current conditions in historical perspective; and it provides spatial and temporal representations of historical droughts.

The Drought Contingency Plan has been approved by TCEQ and is in place to meet periods of extreme drought conditions as they occur. The city's Drought Contingency Plan was amended March 20, 2006, through Ordinance No. 2006-07. A copy of the city's Drought Contingency Plan (Ordinance No. 2006-07)follows Action Item #12 in Section 5, Mitigation Action Items, of this document. A copy of the Drought Contingency Plan is available by request through the City Secretary's Office for the residents of the city. The use of Public Service Announcements and informational brochures can be an effective tool to inform residents of existing conditions and potential damage to their residence by failing to keep foundations hydrated. Public Service Announcements have been developed and are available to be placed on the city's PEG Channel 17, local 1650 AM Radio station, the city's website (www.ci.friendswood.tx.us) and if necessary, on the reader board at Stevenson Park. 2009 MITIGATION ACTION ITEMS DEVELOP A DROUGHT CONTINGENCY PLAN • Conserve the available water supply and protect • Ordinance #2006-07, adopted March 20, the integrity of water supply facilities, with 2006 — Drought Contingency Plan particular regard for domestic water use, • Includes the opportunity to utilize sanitation, and fire protection. alternative water sources and/or • The provisions of the Drought Contingency Plan alternative delivery mechanisms with shall apply to all persons, customers, and property prior approval of the Executive Director of utilizing water provided by the City of the Texas Commission on Environmental Friendswood.

Ongoing • Ensure articles are available for publication in local newspapers,"Focus on Friendswood", PEG Channel 17, etc., beginning of summer season 2010. • Monitor weather conditions to ensure the public is aware of existing drought conditions. • Review and update current Public Service Announcements to ensure data is the most current and reflects any technological advances made with regard to prediction and protection of the public. 72 HAZARD MITIGATION PLAN - City ofF/%endswood WINTER STORMS Severe winter storms can include blizzards, freezing rain, sleet, or dangerous combinations of temperatures and wind. Winter storms can be deceiving. Even a small amount of precipitation can cause problems, especially in areas where snow and ice are unusual occurrences. The State of Texas, Mitigation Plan, states the Texas Panhandle and North Central Texas, around Dallas and Texarkana, are the most vulnerable areas to severe winter storms. Generally, the winter storm season in Texas runs from late November to mid-March. The coldest recorded low temperature for this area was 7.50 at Galveston in February 1899 which also covered Galveston Bay with a thin sheet of ice. Friendswood enjoys a subtropical climate where the growing season extends well into November. Winter days are mild with a few temperature dips below the freezing mark. After an infrequent freeze event, it is not uncommon for the temperature to rise to a balmy 600 or 700 during the day. The entire planning area may be affected by mild to moderate winter storms. We currently do not have enough data to adequately and truthfully determine either the percentage of damage or dollar amount of expected damage to the structures within the city as a result of winter storms. We have included an action item aimed at attempting to address this data gap. PREVIOUS EVENTS AND EXTENT PREVIOUS EVENTS No severe or extreme winter weather events were recorded for the city from 2008 through 2014. Predicting the probability of cold waves and/or unusual winter storms with snow or ice, are difficult at best. Historically speaking, only three events of importance can be found. The damages from such events would also be as difficult to predict as the event itself. Therefore, public awareness through the city's various points of warning would be the optimal conduit of information regarding potential occurrences. EXTENT The entire city has the potential of being affected either by a cold front, cold wave, snow or other winter storm; however, the probability of extreme cold weather events and snow are extremely rare due to the subtropical climate in the region. Primary property losses during these rare occasions is the damage caused by unprotected pipes and plumbing that may freeze. Losses can be minimized by ensuring all pipes are properly insulated and protected. In the event that bridge spans which cross the creeks become impassable, the Public Works Department will spread sand or put up barricades to prevent traffic from using the bridges. If prolonged periods of cold weather are predicted, traffic barriers are utilized to prevent automobiles from using the bridges. No recommendations for structural changes for residential or commercial buildings have been incorporated into planning documents due to the infrequency of these winter events and the minimal effect on the built environment.

The Harris-Galveston Coastal Subsidence District (HGCSD) is the recognized expert in subsidence for this area. The HGCSD maintains a website www.subsidence.org and publishes annual reports that are utilized by communities and agencies in Harris and Galveston Counties. Early oil and gas production and a long history of ground water pumping in the Houston-Galveston June 2000 Houston-Galveston area area have created severe and costly coastal flooding hazards and affected a critical environmental resource— the Galveston Bay estuary. Source: State of Texas Hazard MItgatlon Plan,2013 Update EXTENT The entire city or planning area is susceptible to subsidence. Land subsidence can lead to many problems, including changes in elevation; damage to structures such as storm drains, sanitary sewers, roads, railroads, canals, levees and bridges; structural damage to public and private buildings; and damage to wells. Most commonly, though, subsidence is known for causing an increase in the potential for flooding. The entire planning area includes the following Single Family Structures 12,930 types of structures: Multi-Family Units 1932 Commercial Facilities 309 Schools (Public and Private) 10 Day Cares 32 Churches 17 Government Facilities 21 Utilities 3 Public Infrastructure (sewer &water) 49 The City of Friendswood purchases water from the City of Houston, thus alleviating the need to obtain water from wells. Water usage from the city's water wells is only utilized as a backup when there are extended periods of power outages and water from the City of Houston cannot be conveyed to the city. No additional building restrictions and/or requirements have been initiated and/or adopted with regard to the effects of subsidence. No new irrigation water wells permits have been issued within the previous planning period. In the eastern part of the greater Houston region, near the bay system, subsidence has been controlled by conversion from groundwater to imported surface-water. However, subsidence is accelerating to the west, where ground-water use has increased. Thus, the area of active subsidence has shifted from the low-lying, tide-affected areas towards higher elevations inland.

EMERGENCY GENERATOR PROGRAM (TDRA) Following Hurricane Ike in September 2008, the city utilized Hazard Mitigation Grant and State Homeland Security Grant funding to install generators at city critical facilities— city hall, library, water stations and lift stations (not located in flood zones). The city also ensured that other critical facilities, lift stations and water stations located in a flood zone were equipped with transfer switches to enable the use of portable generators. EMERGENCY GENERATOR MAINTENANCE PROGRAM • The city installed 37 emergency generators (2 water plants, 2 fire stations, 33 lift stations) with TDRA assistance of a disaster recovery grant following Hurricane Ike. • The city entered into an agreement for an emergency generator maintenance program with a contractor to further ensure the city's constant state of emergency readiness. BUYOUT LOTS AND PARKS The city incorporated the buyout lots in the Imperial Gardens Estates subdivision with the 1776 Park, increasing the city's parkland acreage to about 33 acres, and allowing the city to utilize funds within the 1776 Trust for future operation and maintenance costs. These lots were part of the 2001 Tropical Storm Allison buyout program. INTER-JURISDICTIONAL EMERGENCY MANAGEMENT PLAN Friendswood ISD and the city designated an inter-jurisdictional emergency management plan together, providing Friendswood ISD that ability to meet state requirements and enhance joint planning and response efforts during times of disaster. DISPATCH CONSOLES FY11 Urban Area Security Initiative Program (UASI) grant funding was secured to upgrade the dispatch consoles in the police department to enhance communications throughout the Houston UASI region.

The city was established in 1895 as a Quaker (Friends) Colony in northern Galveston County. The colony was originally a farming community of fig and Satsuma orange orchards, and rice fields. GEOGRAPHY&GEOLOGY Friendswood is a progressive suburban city located between downtown Houston and Galveston along the upper Texas Gulf Coast. The majority of Friendswood is in Galveston County and a portion of the city lies north of Clear Creek within southeast Harris County. The city encompasses 23 square miles a d is located in an area described on the Physiographic Map of Texas as the"Gulf Coastal Plain". The city is located on lands ranging from an elevation of ten feet (10') above sea level along Clear Creek, to approximately thirty-five feet (35') above sea level in the extreme northwestern section. Most of the city is located on land ranging from an elevation of twenty-five to thirty-feet (25'to 30') above sea level. The area is a nearly flat stratum with deltaic sand and mud soils. According to the City of Friendswood Flood Insurance Study, the soils within the city are clayey and loamy. Soils are characterized by low infiltration rates and high runoff potential. WATERSHEDS The Clear Creek Watershed, which includes Chigger Creek, Coward's Creek, Mary's Creek and Turkey Creek as tributaries, are of primary concern to the city. CLEAR CREEK Clear Creek is the major water way within the city. The Clear Creek Watershed has an area of approximately 260 square miles, and extends into Brazoria, Fort Bend, Galveston, and Harris Counties. Clear Creek is 45 miles in length and the watershed area varies in width from 2 miles at its upper end to 131/2 miles in the mid-section. Clear Creek originates in Fort Bend County and forms the boundary between Harris, Brazoria, and Galveston Counties as it flows into Galveston Bay. Clear Creek crosses the northern and central sections of the city. Chigger Creek and Turkey Creek are major tributaries of Clear Creek and a major flooding source. CHIGGER CREEK Chigger Creek has a 16.6 square mile drainage area with the lower 8000+ feet affected by the backwater of Clear Creek. The character of flood events in the Chigger Creek watershed is more of a flash flood variety. Residential areas along Chigger Creek are subject to flooding with minimal notice and residents are not able to evacuate valuables out of harm's way. Flood damage claims including damage to both contents and structure have been filed as a result in this watershed. COWARDS CREEK Coward's Creek is an intermittent stream with perennial pools from the confluence with Clear Creek in Galveston County to SH 35 in Brazoria County. The stream length measures 8.1 miles. The character of flood events in the Coward's Creek watershed is of the flash flood variety. Water quickly rises in the area and then drains into Clear Creek. MARY'S CREEK Mary's Creek rises in two forks in northeastern Brazoria County and runs southeast for twelve miles to its mouth on Clear Creek, at Friendswood in Galveston County. The North Fork rises four (4) miles southwest of Pearland and runs for one and one-half(11/2) miles to join the South Fork, which rises six(6) miles southwest of Pearland and runs for three (3) miles to their confluence. 197 HAZARD MITIGATION PLAN - City ofF/%endswood TRANSPORTATION The City of Friendswood is located three (3) miles west of IH-45. The city is served by three major Farm to Market Roads: FM 528, FM 518 and FM 2351. The east/west corridor is FM 528. FM 518 travels northwest to southeast, while FM 2351 travels northeast to southwest. No railroads run within the city's boundaries. Polly Ranch Airstrip is located within the community providing a private aviation location. In nearby Pearland, Pearland Regional Airport provides a hard surface, lighted general aviation runway with fuel service. CLIMATE The climate of the area is sub-tropical. Mild winters and warm summers best characterize the climate. The average summer temperature ranges from a high of 90°F to a low of 74°F.

For example, homes are allowed in residential zoning categories and businesses are allowed in commercial zoning categories. The city has six (6) residential zoning districts and seven (7) non-residential zoning districts. In addition to the types of uses on a zoned piece of property, each zoning district can have landscaping, lot size, building setback and design requirements. Building permits are required for all new construction, reconstruction and renovation. Approximately 714 new residential structures have been added to the city's built environment, and 30 new commercial structures have also been added. The following table depicts the trend in development of residential and commercial construction and renovations within the past six (6) years.

Structures to be constructed in SFHA (special flood hazard areas) shall be constructed to the following guidelines: • All new construction or substantial improvements shall be designed or modified and adequately an chored to prevent flotation, collapse or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyance; • Shall be constructed by methods and practices that minimize flood damage; • All new construction or substantial improvements shall be constructed with materials resistant to flood damage; New residential construction and substantial improvements of any residential structures shall have the lowest floor, including basement, elevated to 24 inches (24'� above the base flood elevation. A registered professional engineer, architect or land surveyor shall submit a certification to the floodplain administrator that the standard is satisfied. Non-residential construction and substantial improvements of any commercial, industrial or other non-residential structure shall either have the lowest floor, including basement, elevated to 24 inches (24') above the base flood level or, together with attendant utility and sanitary facilities, be designed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy. A regist4ered professional engineer or architect shall develop and/or review the structural design, specifications and plans for the construction and shall certify that the design and methods of construction are in accordance with accepted standards of practice as outlined. A record of 201 HAZARD MITIGATION PLAN - City ofFriendswood such certification, which includes the specific elevation in relation to mean sea level to which such structures are flood proofed, shall be maintained by the floodplain administrator. All manufactured homes to be placed within Zone shall be installed using methods and practices which minimize flood damage. Manufactured homes must be elevated and anchored to resist flotation, collapse or lateral movement. Methods of anchoring may include, but are not limited to, use of over-the-top or frame ties to ground anchors. This requirement is in addition to applicable state and local anchoring requirements for resisting wind forces. Special lowest floor elevation requirements: • Zone Ae — the lowest floor elevations shall be a minimum of 24 inches (24') above the elevation given on the latest FEMA FIRM panel for the city; • Zone AO —the lowest floor elevations shall be 36 inches (36:0 higher than the centerline of the road in curb and gutter streets, or the high bank of a roadside ditch on streets with open ditch drainage; • Zone X shaded — lowest floor elevations shall be a minimum of 24 inches (24'� higher than the adjacent natural grade; • Zone X unshaded — • Curb &Gutter Streets —the lowest floor elevation shall be a minimum of 18 inches (18') above the top of curb or a minimum of 12 inches (12'� above the adjacent natural grade, whichever is greater; • Streets with open ditches — slab elevations shall be a minimum of 18 inches (18') higher than the center of the street or a minimum of 12 inches (12') higher than the adjacent natural grade, whichever is greater. Base flood elevation data shall be generated for subdivision proposals and other proposed development, including manufactured home parks and subdivisions, which is greater than 50 lots or five acres, whichever is lesser. All subdivision proposals, included manufactured home parks and subdivisions, shall have adequate drainage provided to reduce exposure to flood hazards. Encroachments into the floodway shall be prohibited, including fill, new construction, substantial improvements and other development within the adopted regulatory floodway unless it has been demonstrated through a no-rise certificate using hydrologic and hydraulic analyses performed in accordance with standard engineering practices that the proposed encroachment would not result in any increase in flood elevations within the community during the occurrence of the base flood discharge. 202 HAZARD MITIGATION PLAN — City OPF/%Bn(ISWOOd CURRENT ZONING MAP f ' a J 1 SFR-E SFR MFR-L ■ MFR-M MFR-GHD J� Q f� ■ MFR-H I MHR %L4 � CSC INC f i • ��r OPD r DD PUD PUD Mixed Use r+ PUD Commerdal PUD NDnCommercial v \� ' ■ Al 8P g% a aaa LI `' I v Open Space Creek 203 HAP M MIUGAUOX PLM — myOfrll eswooe le HAZARD MITIGATION PLAN — City of Friendswood APPENDIX D HISTORY OF NATURAL EVENTS FLOODING FLOODING EVENTS OCCURRING WITHIN THE CITY OF FRIENDSWOOD DATE EVENT DESCRIPTION ESTIMATED DAMAGE COSTS Clear Creek, Chigger Creek, Cowards Creek, and Mary's Creek flooded June 23, 1973 due to protracted rains.The storms responsible for the rains also $50 triggered tornados within the area.The flooding event inundated roads FEMA 398-DRTX within the city, backed up storm drains, caused erosion and road Million washouts.

This storm struck during the holidays when many people were away from their homes. Excessive water damage was associated with broken plumbing and water mains as a result of this event. • 2014: A winter freeze event occurred January 5 and 6, with temperatures dropping below freezing for several hours. A second winter freeze event occurred January 23-25, with snow near the Huntsville area, and freezing rain and temperatures stretching to Galveston. Roads iced over, a few school districts cancelled school, and the majority in Galveston County delayed opening for two hours. SNOW As stated in the State of Texas Mitigation Plan, snowfall of any amount is rare south of a line from Del Rio to Port Arthur. • 2004: A rare and record breaking snowfall occurred Christmas Eve into early Christmas morning. Snowfall amount averaged about three (3") inches in the City of Friendswood. There were no injuries or property damage reported. 223 HAP M MIUGAUOX PLM — myOfrll eswooe fb HAZARD MITIGATION PLAN — City ofF/%endswood HAZARDOUS MATERIALS Within the past twenty-five (25) years, several hazardous materials incidents have occurred within the city.
