I. INTRODUCTION.
THE DETERMINATION OF EQUITABLE FUNDING POLICIES FOR NEW
UTLLITIES IN FRIENDSWOOD CONSTITUTES THE SUBJECT MATTER.
Oti T•j TEXTTHE � T ^ T r T

LEGISLATION WIC- SPECIFIES THAT IN FUTURE YEARS IMPACT
FEES ASSOCIATED WITH NEW CONSTRUCTION MAY BE USED ON!Y
FOR MUNICIPAL UTILITIES SUPPORTING NEW CONSTRUCTION.
NEW RESIDENTS COME TO FRTENDSWOOD TO ENJOY THE
MAGNIFICENT ENVIRONMENT. THEY ALSO BRING LONGINGS FOR
QUALITIES OF THE SERENE LIFE. WHAT THEY DON'T BRING ARE
THE NECESSARY UTILITIES. CREATION OF EQUITABLE POLICY
;FOR FINANCING TRESE FACILITIES IS AN IMPORTANT AND EVEN
MONUMENTAL TASK.
THERE IS NO LESS OF A TASK IN PROTECTING THE PREEXISTING
PUBLIC FROM UNDUE IMPOSITION OF ADDITIONAL FINANCIAL
BORDEN. THE CITY OF ?RIENDSWOOD PROTECTS THE PUBLIC
ROUTINELY THROUGH THE EXERCISE, OF POLICE POWER,
INCLUDING BUILDING CODES, SUBDIVISION REGULATIONS AND
ZONING ORDINANCES, THE LOGICAL EXTENSION OF THIS
CONCEPT OF PROTECTION IMPLIES THAT THE PREEXISTING
POPULATION SHOULD BE LARGELY SPARED THE EXPENSE OF
CONSTRUCTING FACILITIES INTENDED TO SERVE NEW
POPULATIONS. IN THIS SENSE, THE SPECIALIZED PURPOSE OF
IMPACT FEES IS VERY DISTINCT FROM THE MORE GENERAL
PURPOSE OF TAXES SHARED BY THE COMMUNITY AS A WHOLE,
!I. EXPLANATION OF SENATE BILL 336,
THE TEXAS LEGISLATURE RECENTLY PASSED SENATE BILL 336,
REQUIRING MUNICIPALITIES THAT USE IMPACT FEES TO ENACT
EQUITABLE FUNDING POLICIES FOR NEW STREETS AND
UTILITIES. THE MAJOR POINTS OF BILL 336 ARE:
(1) ALL IMPACT FEES MUST BE FOR NEW CONSTRUCTION
ONLY. REPAIR, MAINTENANCE, AND ASSOCIATED COSTS
MAY NOT BE FIGURED INTO THE FEES.
(2) THE PEES CAN ONLY BE ATTRIBUTED TO THE SERVICE
AREAS THAT ARE ACTUALLY BENEFITING FROM THE
IMPROVEMENT.
(3) ONCE THE FEE HAS BEEN ASSESSED TO ANY ENTITY
WITHIN THE SERVICE AREA, CONSTRUCTION OF THE
IMPROVEMENT MUST BEGIN WITHIN 2 YEARS AND BE
COMPLETED IN 5 YEARS.
(4) THE NEW IMPACT FEE PROGRAM MUST BE ADOPTED BY
5
THE CITY NO LATER THAN jUNE, 1990.
A COPY OF SENATE BTL! 339 AND THE 1989
AMENDMENTS IS ATTACHED AS APPEND X "A"

TO BEGIN WORK ON THE NEW IMPACT FEE PROGRAM SOME 3ASIC

MAXIMUM BUILDOUT OF ALL UNDEVELOPED !AND WITHIN THE
FRIENDSWOOD CITY LIMITS. WHERE APPLICABLE, MAXIMUM
ALLOWABLE DENSITIES PER ACRE WERE USED, AS STATED IN THE
FRIENDSWOOD ZONING ORDINANCE.
IV. DESIGN CRITERIA.
AVERAGE RESIDENTIAL, COMMERCIAL AND INDUSTRIAL
WASTEWATER FLOW RATS WERE DETERMINED FROM ACCEPTED
DESIGN MANUALS AND VALIDATED BY THE TEXAS WATER
COMMISSION AS ACCEPTED DESIGN ASSUMPTIONS. BASICALLY,
AN AVERAGE WASTEWATER FLOW RATE WAS DETERMINED FOR EACH.
ZONING CLASSIFICATION OUTLINED ABOVE. TO THESE RATES, A
PEAK FACTOR AND AN INFILTRATION FACTOR WERE APPLIED. TO
BEGIN INVESTIGATIONS, THE CITY WAS DIVIDE UP INTO
HYPOTHETICAL DEVELOPMENT AREAS, AND FLOW RATES WERE
COMPUTED FOR EACH, AS OUTLINED IN APPE'ND,IX "B". IT
SHOULD BE NOTED THAT APPENDIX "B" ALSO LISTS THE
PUBLISHED REFERENCES FOR DESIGN ASSUMPTIONS USED
THROUGHOUT THIS STUDY.
V. REVIEW OF MASTER SEWER ?SAN '.'SAP.
FUTURE SANITARY SEWER NEEDS WITHIN THE CITY 0n
FRIENDSWOOD WERE THEN DETERMINED AND THE PROPOSED
CAPITAL !M?ROVF'MENTS WERE GRAPHICALLY REPRESENTED ON THE.
WALL MAP DISPLAYED AS PART OF THIS STUDY. THESE
PROJECTS WERE:
1. INDUSTRIAL DEVELOPMENT AREA SEWER LINE. THIS IS A
:3,870 FT. LINE RANGING IN SIZE FROM 18 TO 24 INCH2S,
WITH ONE ASSOCIATED LIFT STATION. THIS LINE WILL RUN
ALONG THE EAST SIDE OF CLEAR CREEK NORTH OF F.M.
2351, AND WILL PROVIDE SERVICE TO ANTICIPATED
INDUSTRIA! DEVELOPMENT .IN THE EXTR3ME NORTHERN
0
PORTIONS OF TOWN.
2, MELODY LANE DEVELOPMENT AREA SEWZR LINE. THIS IS A
8575 ?T . =2 CONSISTING OF :8" PIPE. :' W Ll as\
ALONG ` H3 .EAST SIDE OF CLEAR CR22K NORTH OF F . `!
2351, AND WILL SERVE ANTIC'PA'TED SFR DEVEI.:0?`rEN7
BETW22N CLEAR CREEK AND M31ODY LANE.
3. INDUSTRIAL/MELODY LANE JOINT =T STATION AND FORCE
MAIN, THIS IS LARGD ;: 7FT STATION AND 20,500 FT. 15''
7ORC 2 ?FAIN TAKING THE WASTEWATER FROM BOTH THE
INDUSTRIAL AND THE MELODY LANE SEWER LINES DIRECTLY
TO T'1E 3LACKHAWK REGIONAL SEWAGE TREATMENT ?LAN'T .
PROPOSED ALIGNMENT OF THIS FOZCr MAIN 1S !LLUSTRATED
ON THE WALL MAP EXHIBIT.
4. FALLING LEAF SEWER LINE, THIS IS A 4200 FT. LINE
CONSISTING 07 15" PIPE RUNNING ALONG FALLING LEAF
DERIVE SOUTHWEST OF G.REENBRIAR DRIVE. THIS LINE WILL
SERVE NEW SFR DEVELOPMENT IN THAT AREA OF TOWN.
5. TRUNK LINE "CH". THIS IS A 13,200 FT. LINE WITH PIPE
SIZE'S RANGING FROM 30" TO 42" . THIS PROPOSED LINE
WOULD BEGIN AT THE NORTH END OF MISSION ESTATES AND
RUN NORTHERLY ALONG A TRIBUTARY OF CHIGGER CREEK
BEHIND FALCON RIDGE TO THE REAR OF FOX MEADOWS. FROM
HERE THE LINE RUNS ALONG THE SOUTH SIDE OF CHIGGER
CREEK TOWARD POLLY RANCH.
b. 'TRUNK LINE "CN". THIS IS A 10,050 FT. LINE WITH PIPE
SIZES RANGING FROM 15" TO 24". IT BEGINS NEAR
WINDSONG SUBDIVISION AND RUNS EAST ALONG THE SOUTR
SIDE OF CHIGGER CREEK TO FOX MEADOWS, TYING INTO
TRUNK LIME "OH".
7. TRUNK LINE "CS". THIS IS A 7,200 FT. LINE WITH PIPE
SIZES RANGING FROM 12" TO 24". IT RUNS FROM THE
SOUTHERN PART OF SLOWS SJ3D.IVISION IN A
NORTHEASTERLY DIRECTION TO A POINT JUST SOUTH OF
POLLY RANCH.
8. CRAZY HORSE LIFT STATION AND FORCE MAIN. `HIS WILL
BE A HIGH CAPACITY LIFT STATION AND 5100 FT. OF 30''
FORCE MAIN THAT WILL CARRY FLOW FROM TRUNK LINES
"CH", "CN", AND "CS" DIRECTLY TO THE BLACKHAWK
REGIONAL SEWER TREATMENT PLANT. LOCATION OF THESE
IMPROVEMENTS IS SHOWN ON THE WALL EXHIBIT.
9. SOUTH PANHANDLE SEWER LINE. THIS IS A 7000 FT.
LINE CONSISTING OF 24" PIPE. IT WILL RUN FROM
COUNTRY CLUB ROAD SOUTH ALONG F.M. 528 TO ITS
TERMINUS AT TOWER ESTATES SUBDIVISION. THIS
.IMPROVEMENT WILL SERVE SFR AND CSC DEVELOPMENT IN THE
SOUTHERN PORTIONS OF THE CITY OF FRIENDSWOOD .

THIS LIFTSTA

WILL BE THE ELIMINATION OF THE TOWER ESTATES
;RHATM='\T PLANT.
VI. GENERATION OF SIZES AND COSTS FOR SPECIFIC SEWER
IMPROVEMENTS.
PIPE SIZES AND LIFT STATION REQUIREMENTS POR EACH
PROJECT WERE DETERMINED AND TOTAL CONSTRUCTION ESTIMATES
WERE DERIVED PROM ESTIMATES OBTAINED FROM LOCAL
MATERIALS SUPPLIERS.
THE FIRST STEP WAS TO DETERMINE THE AREAS THAT WOULD BE
SERVED BY EACH IMPROVEMENT. THESE "SERVICE AREAS" WERE
DELINEATED USING THE TOPOGRAPHIC MAP OF THE CITY OF
FRIZNDSWOOD, WITH SERVICE AREA BOUNDARIES COINCIDING
WITH EITHER GEOGRAPHICAL HIGHS OR LOGICAL DIVISIONS IN
THE CITY SEWER SYSTEM. ONCE THESE BOUNDARIES WERE SET,
THE TOTAL FLOW POSSIBLE PROM EACH AREA WAS DSTZR yNED,
USING THE AVERAGE FLOW x 2.5 PEAK FLOW FACTOR T
INFILTRATION. NECESSARY PIPE DIAMETER WAS THEN
CALCULATED USING THE FORMULA:
0 = (2.159Qri / S !/2) 3/8
WHERE D = PIPE DIAMETER
Q = TOTAL FLOW IN MOD x 1.5472 CFS/MGD
n = MANNING COEFFICIENT = .014
S = SLOPE IN FT/FT
ONCE THE PIPE SIZE WAS DETERMINED, TOTAL PIPE COSTS WERE
FOUND USING COST PER FOOT QUOTATIONS. A FACTOR OF 2.25
WAS THEN APPLIED TO GIVE A TOTAL INSTALLED COST.
MANHOLES WERE ESTIMATED AT A COST OF $1675.00 EACH.
COST ESTIMATES USED ARE AS FOLLOWS:

A BREAKDOWN OF PIPE SIZING AND COST ESTIMATES FOR
INDIVIDUAL PROJECTS IS PROVIDED IN APPENDIX "C".
VII. GENERATION OF SERVICE UNITS.
SENATE BILL 336 STIPULATES THAT AN IMPACT FEE IS A
CHARGE THAT MUST BE APPLIED TO A SERVICE UNIT. A
SERVICE UNIT IS A STANDARDIZED UNIT OF DISCHARGE
ATTRIBUTED TO INDIVIDUAL DEVELOPMENT UNITS. FOR THE
PURPOSES OF THIS STUDY A SERVICE UNIT (OR EQUIVALENT
FLOW UNIT) WILL BE EQUAL TO 1355 GALLONS PER ACRE PER
DAY OF WASTEWATER GENERATION.
CALCULATIONS OF SERVICE UNITS (EQUIVALENT FLOW UNITS)
THESE CALCULATIONS ARE BASTED ON A SFR DENSITY OF 2.7
BUILDING UNITS PER ACRE. THE PROJECTED MAXIMUM FLOW FOR
1 ACRE OF SF'R LAND = (2.7 BUILDING UNITS PER ACRE x 3
PEOPLE PER BUILDING UNIT x 130 GALLONS OF WASTEWATER PER
,PERSON PER DAY) x 2.5 PEAK FLOW FACTOR + 1025 GADLONS
PER ACRE PER DAY INFILTRATION = 3658 GALLONS PER ACRE
PER DAY FOR SFR .

3658 G1A\D DIVIDED 5Y 2.7 3U11DIXG ON17S PER ACRE = 1355

Vill . DERIVATION OF SERVICE UNITS PER SERVICE AREA,
ONCE, A SERVICE UNIT HAS BEEN DEFINED (AS ABOVE), THE
UMBER OF SERVICE UNITS PER SPECIFIC SERVICE AREA CAN BE
CALCULATED. BASICALLY, THE NUMBER OF ACRES OF EACH
ZONING CLASSIFICATION 1N EACH SERVICE AREA IS MULTIPLIED
BY THE APPROPRIATE EQUIVALENT FLOW UNITS/ACRE NUMBER
SHOWN IN COLUMN 4 OF THE PREVIOUS CHART.
FOR EXAMPLE, THE FALLING LEAF SERVICE AREA CONSISTS OF
254.6 ACRES OF LAND, ALL ZONED SFR. THE TOTAL NUMBER OF
SERVICE UNITS THEN IS 254.6 ACRES x 2.7 EQUIVALENT FLOW
UNITS PER ACRE = 687.42 EQ. FLOW UNITS OR 687 SERVICE
UNITS FOR THAT SERVICE AREA.
ANOTHZR EXAMPLE WOULD BE THE SOUTH PANHANDLE SLRVICE
AREA "A". THAT AREA CONSISTS OF 941.3 ACRES, 900 OF
WHICH ARE ZONED SFR, AND 41.3 ZONED CSC. 900 ACRES x
2.7 EFUs/ACRE = 2430 EFUs. 41.3 ACRES x 3.3 EFUs/ACRE
136 EFUs. THE TOTAL NUMBER OF EFUs (OR SERVICE UNITS)
FOR THIS SERVICE AREA = 2430 + 136 = 2566 EFUs (OR
SERVICZ UNITS). NOW, TO COME UP WITH AN IMPACT FEZ FOR
EACH UNIT, THE CONSTRUCTION COSTS FOR THE PROPOSED
