During the construction process, soil is the most vulnerable to erosion by wind and water. This eroded soil endangers water resources by reducing water quality, and causes the silting of aquatic habitat for fish and other desirable species. Eroded soil also necessitates repair of sewers and ditches, and the dredging of waterways. In addition, clearing grading during construction causes the loss of native vegetation necessary for terrestrial and aquatic habitat, and to provide a healthy living environment for citizens of the City of Friendswood. The purpose of this ordinance is to safeguard persons, protect property, prevent damage to the environment and promote the public welfare by guiding, regulating, and controlling the design,construction,use,and maintenance of any development or other activity which disturbs or breaks the topsoil or results in the movement of earth on land in the City of Friendswood. Sec. 78-251. Permits. It shall be unlawful for any person to conduct any land- disturbing activity without a permit issued by the City Manager or his/her designee. (a) No person shall be granted a permit for land-disturbing activity which would require the uncovering of 1 acre or more, without the approval of an erosion and sediment control plan by the City of Friendswood City Manager or his/her designee. (b) An erosion and sediment control plan is not required for the following activities: (1) Any emergency activity immediately necessary for the protection of life, property or natural resources; or (2) Existing nursery and agricultural operations conducted as a permitted main or accessory use. (c) Each application for a permit to allow land-disturbing activities shall include a statement that any land clearing, construction, or development involving the movement of earth shall be in accordance with the erosion and sediment control plan, and that a site operator shall be on site on all days where construction or grading 15 activity takes place. Sec. 78-252. Review and approval. The City of Friendswood City Manager or his/her designee will review each erosion and sediment control plan to determine its conformance with the provisions of this local regulation. The City of Friendswood City Manager or his/her designee shall,in writing: (1) Approve the plan; (2) Approve the plan subject to such reasonable conditions as may be necessary to secure substantially the objectives of this regulation, and issue the approval subject to these conditions; or (3) Disapprove the plan,indicating the deficiencies and the procedure for submitting a revised application and/or submission. Sec. 78-253. Design Requirements. Grading, erosion control practices, sediment control practices, and waterway crossings shall meet the design criteria set forth in the most recent version of the City's Design Criteria Manual, and shall be adequate to prevent transportation of sediment from the site to the satisfaction of the City of Friendswood City Manager or his/her designee. Sec. 78-254. Modifications to the plan. Major amendments of the erosion and sediment control plan shall be submitted to the City of Friendswood City Manager or his/her designee and shall be processed and approved, or disapproved, in the same manner as the original plans. Field modifications of a minor nature may be authorized by the City of Friendswood City Manager or his/her designee by written authorization to the permitee. Sec. 78-255. Clearing and Grading. Clearing and grading activities,shall not be permitted,except when in compliance all other chapters of this Code. Clearing techniques that retain natural vegetation and retain natural drainage patterns,as described in the storm water design manual,shall be used to the satisfaction of the City of Friendswood City Manager or his/her designee. Sec. 78-256. Inspection. (a) The City of Friendswood City Manager or his/her designee shall make inspections as hereinafter required and shall either approve that portion of the work completed or shall notify the permitee that the work fails to comply with the erosion 16 and sediment control plan as approved. Plans for grading,stripping,excavating,and filling wark bearing the stamp of approval of the City of Friendswood City Manager or his/her designee shall be maintained at the site during the progress of the work. (b) The permitee or his/her agent shall make regular inspections of all control measures in accordance with the inspection schedule outlined on the approved erosion and sediment control plan(s). The purpose of such inspections will be to determine the overall effectiveness of the control plan, and the need for additional control measures. All inspections shall be documented in written form and submitted to the City of Friendswood City Manager or his/her designee at the time interval specified in the approved permit. (c) The City of Friendswood City Manager or his/her designee shall enter the property of the applicant as deemed necessary to make regular inspections to ensure the validity of the reports filed under the above mentioned section. Sec. 78-257. Enforcement. Stop-Work Order; Revocation of Permit. In the event that any person holding a site development permit pursuant to this ordinance violates the terms of the permit, or implements site development in such a manner as to materially adversely affect the health, welfare, or safety or persons residing or working in the neighborhood or development site so as to be materially detrimental to the public welfare or injurious to property or improvements in the neighborhood, the City of Friendswood City Manager or his/her designee may suspend or revoke the site development permit,in addition to any other penalty provisions contained in this ordinance. DIVISION 4—POST CONSTRUCTION STORM WATER RUNOFF Sec. 78-260. General provisions. (a) Findings of Fact. It is hereby determined that: (4) Land development proj ects and associated increases in impervious cover alter the hydrologic response of local watersheds and increase storm water runoff rates and volumes, flooding, stream channel erosion, and sediment transport and deposition; (5) This storm water runoff contributes to increased quantities of water-borne pollutants, and; (3) Storm water runoff, soil erosion and non-point source pollution can be controlled and minimized through the regulation of storm water runoff from development sites. 17 Therefore,the City of Friendswood establishes this set of water quality and quantity policies applicable to all surface waters to provide reasonable guidance for the regulation of storm water runoff for the purpose of protecting local water resources from degradation. It is determined that the regulation of storm water runoff discharges from land development proj ects and other construction activities in order to control and minimize increases in storm water runoff rates and volumes, soil erosion, stream channel erosion, and non-point source pollution associated with storm water runoff is in the public interest and will prevent threats to public health and safety. (b) Purpose. The purpose of this ordinance is to establish minimum storm water management requirements and controls to protect and safeguard the general health, safety, and welfare of the public residing in watersheds within this jurisdiction. This ordinance seeks to meet that purpose through the following objectives: (3) minimize increases in storm water runoff from any development in order to reduce flooding, silting, increases in stream temperature, and stream bank erosion and maintain the integrity of stream channels; (2) minimize increases in non-point source pollution caused by storm water runoff from development which would otherwise degrade local water quality; (6) minimize the total annual volume of surface water runoff which flows from any specific site during and following development to not exceed the pre- development hydrologic regime to the maximum extent practicable; and (4) reduce storm water runoff rates and volumes, soil erosion and non-point source pollution,wherever possible,through storm water management controls and to ensure that these management controls are properly maintained and pose no threat to public safety. (c) Applicability. This ordinance shall be applicable to all subdivision or site plan applications,unless eligible for an exemption by the City of Friendswood City Manager or his/her designee under the specifications of this ordinance.The ordinance also applies to land development activities that are smaller than the minimum applicability criteria if such activities are part of a larger common plan of development that meets the following applicability criteria, even though multiple separate and distinct land development activities may take place at different times on different schedules. In addition, all plans must also ensure that established water quality standards will be maintained during and after development of the site and that post construction runoff levels are consistent with any local and regional watershed plans. 18 To prevent the adverse impacts of storm water runoff,the City of Friendswood has developed a set of performance standards that must be met at new development sites. These standards apply to any construction activity disturbing one(1) or more acres of land. The following activities may be exempt from these storm water performance criteria: 1. Additions or modifications to existing single family structures: 2. Developments that do not disturb more than 1 acre of land,provided they are not part of a larger common development plan; or 3. Repairs to any storm water treatment practice deemed necessary by the City of Friendswood City Manager or his/her designee. When a site development plan is submitted that qualifies as a redevelopment project as defined in this ordinance, decisions on permitting and on-site storm water requirements shall be governed by special storm water sizing criteria found in the current storm water design manual. This criterion is dependent on the amount of impervious area created by the redevelopment and its impact on water quality. Final authorization of all redevelopment projects will be determined after a review by the City of Friendswood City Manager or his/her designee. (d) Design Criteria Manual. The Design Criteria Manual includes a list of acceptable storm water treatment practices,including the specific design criteria and operation and maintenance requirements for each storm water practice.The manual may be updated and expanded from time to time, at the discretion of the City,based on improvements in engineering, science, monitoring and local maintenance experience. Storm water treatment practices that are designed and constructed in accordance with these design and sizing criteria shall meet the minimum water quality performance standards. Sec. 78-261. Permit Procedures and Requirements. (a) Permit Required. No land owner or land operator shall receive any of the building, grading or other land development permits required for land disturbance activities without first meeting the requirements of this ordinance prior to commencing the proposed activity. (b) Application Requirements. Unless specifically excluded by this ordinance, any land owner or operator desiring a permit for a land disturbance activity shall submit to the City of Friendswood City Manager or his/her designee a permit application on a form provided for that purpose. 19 Sec. 78-262. Egemptions to Storm Water Management Requirements. (a) Exemptions for Providing Storm water Management. (1) Every applicant shall provide for storm water management as required by this ordinance, unless a written request is filed to waive this requirement. Requests to waive the storm water management plan requirements shall be submitted to the City of Friendswood City Manager or his/her designee for approval. (2) The minimum requirements for storm water management may be waived in whole or in part upon written request of the applicant, provided that at least one of the following conditions applies: A. It can be demonstrated that the proposed development is not likely to impair attainment of the objectives of this ordinance; B. Alternative minimum requirements for on-site management of storm water discharges have been established in a storm water management plan that has been approved by the City of Friendswood City Manager or his/her designee and the implementation of the plan is required by local ordinance; C. Provisions are made to manage storm water by an off-site facility.The off-site facility is required to be in place,to be designed and adequately sized to provide a level of storm water control that is equal to or greater than that which would be afforded by on-site practices and there is a legally obligated entity responsible for long-term operation and maintenance of the storm water practice; or D. Non-structural practices will be used on the site to reduce: a) the generation of storm water from the site, b)the size and cost of storm water storage and c) the pollutants generated at the site. These non-structural practices will be explained in detail in the storm water design manual and the amount of credit available for using such practices shall be determined by the City of Friendswood, City Manager or his designee. (3) In instances where one of the conditions above applies, the City of Friendswood City Manager or his/her designee may grant a waiver from strict compliance with these storm water management provisions, as long as acceptable mitigation measures are provided. However, to be eligible for a variance, the applicant must demonstrate to the satisfaction of the City of Friendswood City Manager or his/her designee that the variance will not result in the following impacts to downstream waterways: 20 A. Deterioration of existing culverts, bridges, and other structures; B. Degradation of biological functions or habitat; C. Accelerated stream bank or streambed erosion or silting; or D. Increased threat of flood damage to public health, life,property." Section 3. In the event any section, paragraph, subdivision, clause, phrase, provision, sentence,or part of this Ordinance or the application of the same to any person or circumstance shall for any reason be adjudged invalid or held unconstitutional by a court of competent jurisdiction, it shall not affect,impair,or invalidate this Ordinance as a whole or any part or provision hereof other any part or provision hereof other than the part declared to be invalid or unconstitutional; and the City Council of the City of Friendswood, Texas,declares that it would have passed each and every part of the same notwithstanding the omission of any and every part of the same notwithstanding the omission of any such part thus declared to be invalid or unconstitutional,or whether there be one or more parts.
