1. INTRODUCTION
A Capital Improvements Plan and Impact Fee Study dated March 21, 1990 regarding the fees necessary to
offset the costs of specific water and sewer line projects was prepared as a part of the process described
In legislation adopted by the State of Texas in 1987 and amended In 1989. Impact fees related to plant
capacity, both water supply and wastewater treatment, were not considered for various reasons.
Preliminary Input in response to the Fee Study, however, has been supportive of an expanded approach in
the Implementation of Impact fees that would recognize past expenditures by the City of Friendswood for
surface water supply and wastewater treatment capacity. Such expenditures, to the extent that they are
clearly necessitated for the support of new development, may be included in the calculation of Impact
Fees.
The following sections address the adoption of City Wide Impact fees for new development with regard to
facilities required to provide surface water and wastewater treatment as necessary to support the
continued growth of the City of Friendswood consistent with the projections In the Capital Improvements
Plan.
11. SURFACE WATER SUPPLY FACILITIES
The City of Friendswood has been Involved for a number of years In plans to reduce dependency on
groundwater in order to comply with goals designed to reduce continued land subsidence In this area as
established by the Harris -Galveston Coastal Subsidence District. The Subsidence District has, within the
last few years adopted a policy that limits groundwater withdrawal to specific levels depending on location
within the two county area. After considering a number of surface water alternatives, the City of
Friendswood elected to purchase an allocation in the Southeast Water Purification Plant currently under
constructlon by the City of Houston. In addition to the purchase of surface water capacity, the
Implementation of this alternative has dictated the construction of water transmission lines and water plant
components designed to convey and handle the water received from the Southeast Plant. To the extent
that the surface water allocation and related facilities will benefit future development, it Is appropriate to
recognize the costs of these improvements as a part of the impact fee structure.
The City of Friendswood's surface water facilities may be grouped into three categories; Surface Water
Capacity, Surface Water Transmission, Pumping and Storage Facilities and System Wide Improvements to
Accommodate Surface Water Distribution.

Surface Water Capacity
The surface water allocation of 3.0 mgd is sufficient to accommodate a finite number of connections which
can be determined from historical water utilization. As referenced in the Impact Fee Study, water
consumption In Friendswood in 1989 averaged approximately 2.8 mgd for 7,662 equivalent connections.
The 80% surface component of current water requirements then Is approximately 2.25 mgd which leaves a
balance of 0.75 mgd In unused capacity for new development. Assuming the current use rate, 0.75 mgd
will accommodate an additional 2,554 equivalent. connections. The Capital Improvements Plan assumes a
total of 4,819 additional connections over the term of the planning period which implies that additional
surface water capacity will have to be purchased during the next ten years. If the unit cost of additional
surface water capacity Is different than the Initial allocation In the Southeast Plant, adjustments will have to
be made in future updates of the Impact Fee structure.
The total cost of the City's Initial purchase of surface water including financing and issuance costs as
Itemized on Exhibit "A" is $5,420,437. The unit cost, based on 7,662 existing and 2,554 new connections is
$531.
Surface Water Transmission, Pumping and Storage Facilities
There are a number of projects and studies that have been accomplished in connection with the
construction of facilities designed to convey surface water to the City of Friendswood and provide storage
and pumping capacity to distribute the water to the City's customers. The summation of these projects are
estimated to be sufficient for Friendswood's requirements through the 50% build out level, or 12,500
equivalent connections based on current projections of 25,000 connections at 100% build out. Ultimately,
a second surface water line Is envisioned along the alignment of Beamer and FM-2351 with the attendant
storage and pumping facilities to complete the conveyance and handling of surface water for the City of
Friendswood.
The total cost of the surface water transmission, pumping and storage facilities relevant to the 50% level of
build out Including financing and issuance costs as Itemized on Exhibit "A" is $1,959,459, The unit cost,
based on 7,662 existing and 4,819 pro/ected new and 19 future (that is, connections anticipated beyond
the ten year limitation of the Capital Improvements Study) connections Is $157.

System Wide Improvements
Several components of the surface water conversion effort Including the Surface Water Monitoring
Equipment and the Modifications to Existing Water Plants to Accommodate Surface Water are not
particularly sensitive to "levels of build out" and are intended to apply to the overall system. To that extent,
these improvements with a cost of $574,439 Including financing and Issuance costs as itemized on Exhibit
"A" are proposed to apply to the entire 25,000 connections projected for the City of Friendswood. The unit
cost, based on 7,662 existing and 4,819 projected new and 12,519 future connections is $23.
The Proposed Impact Fee For All Surface Water Related Facilities As Described Above Is $711 Per
Equivalent Service Unit.
III. WASTEWATER TREATMENT FACILITIES
The City of Friendswood has purchased capacity In each of the two construction phases of the Blackhawk
Wastewater Treatment Plant. The City In combination with WCID 108 obtained 2.0 mgd capacity in the.
Initial phase of construction at no cost due to EPA participation. An additional 0.5 mgd capacity was
purchased by Clearwood Improvement District in that same construction phase for a cost of approximately
$272,432, Upon annexation into the City of Friendswood, the Clearwood treatment capacity and debt was
assumed by Friendswood. Essentially all of the 2.5 mgd capacity referenced above, however, is being
used to accommodate existing development. The 2.375 mgd treatment capacity obtained by the City of
Friendswood In the second construction phase for a cost of $467,316 Is available to support new
development. Assuming an average rate of flow of 390 gpd per connection used as the basis of an
Equivalent Service Unit In the Impact Fee Study, the additional 2.375 mgd will provide capacity for.an
approximately 6,090 additional connections which equates to an Impact fee of $77 per equivalent service
unit.
The Proposed Impact Fee For Wastewater Treatment Facilities As Described Above Is $77 Per
Equivalent Service Unit.

IV. PROPOSED MODIFICATIONS TO THE IMPACT FEE STRUCTURE
A, Delete the surcharge calculated for the preparation of the Impact Fee Study and Capital
Improvements Plan as a part of the fees proposed In connection with the Water Distribution and
Wastewater Collection lines specific to particular service areas and Incorporate It Instead as a part
of the City wide fee proposed In connection with the Surface Water and Wastewater Treatment
Facilities.
B, Delete the Impact Fee proposed for Wastewater Treatment specific to the Bay Area Boulevard
Service Area In consideration of the City Wide fee proposed for treatment capacity.
C. Charge a fee of $794 per connection for all connections regardless of where they occur in the City
for Surface Water Facilities ($711), Wastewater Treatment Capacity ($77) and Preparation of the
Impact Fee Study and Capital Improvements Plan ($6).
D. Charge additional fees as appropriate for specific service areas in conformance with the Impact
Fee Study and Capital Improvements Plan,
