Presented herein are the results of the Land Use Maps and CIP. The City of Baytown 2020 Comprehensive Plan was to be used as the basis of growth projections and land use. However, after review, PBS&J advised that the projections were unrealistically high and would significantly distort CIP requirements. Revised growth and land use projections were submitted for consideration and approved by the City. Although the City has adopted several planning documents, there are no water and wastewater master plans that address long-term growth of the city or its extraterritorial jurisdiction ("ETJ"). The Master Plan and CRF study were conducted in compliance with Local Government Code, Title 12, Planning and Development, Chapter 395, et seq, Financing Capital Improvements Required by New Development in Municipalities, Counties, and Certain Other Local Governments. The report was developed from data provided by the City of Baytown 2020 Comprehensive Plan and City staff. It also draws upon previous reports and utility studies that were performed for the City. During the study period, we identified proposed general benefit capital improvement projects totaling $4,847,200 for water and $34,771,500 for wastewater that will be needed through 2012. Where new or additional capacity was needed, sizing was made in anticipation of future needs. The increase in need for utilities that will be attributable to new development was determined by the difference between existing and projected demand within the service area based on the approved land use assumptions. The costs of those facilities that will be used by or attributed to new development are calculated in a separate report prepared in conjunction with this report entitled "City of Baytown Maximum Impact Fee Determination". 460611.00/030289 1-1 2.0 STUDY OBJECTIVES In anticipation of continued growth, this study is being provided that identifies the probable growth of the city through 2020, and the capital improvements that will be needed to satisfy the growth projections for the planning area, which comprises the City and a portion of its ETJ. The maximum allowable impact fee will be determined in a separate report. The study is developed as follows: • Population and land use projections - These projections are derived from past and anticipated growth and form the basis for which service demands are derived • The existing and anticipated demand for water and wastewater were developed from records of past and present consumption and anticipated changes that are likely to occur. Water and Wastewater CIP's for 2012 and 2020 were developed to serve the projected land uses and resulting utility demands for those periods. The 2012 CIP becomes the basis for the City's maximum Impact Fee Determination. Proposed improvements were selected to serve development that is expected to occur within the planning area, but at densities less than full development. The resulting systems may have an overall capacity in excess of projected requirements, but at a cost that will not restrain growth. Probable construction costs for proposed improvements include basic items plus appurtenances, as well as allowances for engineering and contingencies. The costs do not include allowances for private crossings, legal or fiscal costs, or rights -of -way. The probable costs are based on current -year dollars and average unit costs. 460611.00 / 030289 2-1 3.0 POPULATION PROJECTIONS Our original scope of work called for review of the City's existing 2000 Comprehensive Plan (the "Plan") and the use of the Plan's population and land use projections for development of the Utility Master Plan and Maximum Impact Fee Study and report. The 2000 census, which was released after the Plan was published, and our evaluation resulted in the issuing of an Interim Report, Attachment 1, wherein it was concluded that the Plan's projections were not supportable and new projections were recommended. The City subsequently concurred with our recommended projections. Census reports show that Baytown's rate of growth has not been very strong in recent years. Between 1980 and 1990, the city grew at an annual rate of 1.2 percent; between 1990 and 2000, the annual rate of growth was 0.4 percent. Although the City currently has an aggressive community development program, it will take time for the development program to be implemented and the growth rate to accelerate. Our analysis of recent city growth trends and data available from statistical centers could not support the high rate of growth presented in the Comprehensive Plan. Historical population projections and actual growth are shown in Table 3.1. A number of public authorities have produced population estimates and projections for Texas communities. Discussed below are projections by the Houston -Galveston Area Council ("HGAC") and the Texas Water Development Board ("TWDB"). The projections have not been revised by these planning agencies to reflect the 2000 census; therefore, some discrepancy exists between the various sources for the year 2000. Nonetheless, long-range population projections are best made using extended period projections maintained by demographic agencies with adjustments as necessary to account for known variations. HGAC makes population forecasts for Regional Area Zones ("RAZ") in Harris County. HGAC projections are based on the relocation of people into Harris County, transportation forecasts, government and real estate information, land use criteria, and census tract information. The RAZ do not necessarily correlate to city boundaries, but the zones are small enough that a reasonable correlation can be made. Baytown is in three RAZ--85, 86, and 88. The HGAC forecasted annual growth in these zones is shown below: HGAC Forecast of Average Population Growth RAZ 2000 to 2010 2010 to 2020 85 0.23% 0.77% 86 0.27% 0.78% 88 0.61% 1.07% 460611.00 / 030289 3-1 Using the difference between the 2000 city census and the 2000 HGAC estimate, an approximation can be made of the HGAC for the Baytown area. Using HGAC projections, the city population would be 68,428 in 2010 and 74,003 in 2020. TWDB has also developed projections for municipalities as part of the statewide water -planning program. The TWDB projections are based upon historical population and anticipated number of water permits. The TWDB forecasted annual growth for the city is shown below: TWDB Forecast of AveraEe Population Growth City of Baytown 2000 to 2010 2010 to 2020 1.46% 1.62% The TWDB over -estimated Baytown's 2000 population and showed it to be 80,949 as compared to the census number of 66,430. If the projections are adjusted using the 2000 census data as a starting point, the 2010 population would be projected to be 76,028 and the 2020 population would be 88,115. Should the city continue growing at the rate experienced between 1990 and 2000, its population in 2010 would be 69,135, and in 2020 its population would be 71,951. Should the city grow at a rate experienced between 1980 and 1990, its population in 2010 would be 74,477 and in 2020 it would be 83,499. The City's annexation plans and development initiatives can be expected to result in growth in excess of that which occurred between 1990 and 2000. The 2000 Comprehensive Plan's projections are considered to be unreasonably high and those of the TWDB to be somewhat excessive. A compromise between the TWDB and the HGAC projections was considered a reasonable target. A growth rate of 1.2 percent, or that which was experienced by the city between 1980 and 1990, provides the compromise being sought. This growth rate results in a projected population of 74,477 persons in 2010 and 84,449 persons in 2020. The various populations discussed are shown in Figure 3.1 for comparison. These population projections were recommended to the City and approved for use in the study. 460611 00 / 030289 3-2 PBEI I 1 I I I i I I 1 I I I I I I I I I Table 3.1 HISTORICAL AND ESTIMATED POPULATION, BAYTOWN AND HARRIS COUNTY Baytown 2020 Comprehensive Plan Update Baytown Texas Baytown Harris County Year Number Percent Change Number Percent Change 1950 22,983 806,701 1960 28,159 22.5% 1,243,158 54.1% 1970 43,980 56.2% 1,741,912 40.1 1980 56,923 29.4% 2,409,547 38.3% 1990 63,850 12.2% 2,818,199 17.0% 1998 70,412 7.7% 3,178,995 12.8% HISTORICAL POPULATION FROM CENSUS, BAYTOWN AND HARRIS COUNTY Baytown Harris County Year Number Annual Ave Change Number Annual Ave Change 1950 22,983 806,701 1960 28,159 2.1% 1,243,158 4.4% 1970 43,980 4.6% 1,741,912 3.4% 1980 56,923 2.6% 2,409,547 3.3% 1990 63,850 1.2% 2,818,199 1.6% 2000 66,430 0.4% 3,400,578 1.9% M M OM— NM — r a N N i— r-- NMI MO M MB 140000 120000 100000 80000 0 a 0 a 60000 40000 20000 0 Exhibit 3-1 Population Projections City of Baytown IDS f �"i �:� xxlp.�.�.

As an economy measure, Baytown negotiated with PBS&J on the Comprehensive Plan, as well as the associated Land Use GIS database. Errors were found in the Comprehensive Plan, which indicated inconsistencies between the plan's data and the 2000 Census population calculations, thereby skewing the forecasted population growth. In addition to the inconsistencies in the Comprehensive Plan data, large inconsistencies were also found between the Land Use GIS database and the written Comprehensive Plan, as well as significant spatial inaccuracies in the Land Use GIS database. Since the City of Baytown had already adopted the Comprehensive Plan's current Land Use delineation, PBS&J did not make any changes. Therefore, some inconsistencies occur between the current Land Use delineation provided by the Comprehensive Plan and the projected Land Use for 2012 and 2020 provided by PBS&J, and result from the City of Baytown and PBS&J working together to build and rectify land use projections for 2012 and 2020. 4.2 DATA PREPARATION Before initiating land use analysis, the original data received from the City by means of its 2000 Comprehensive Plan had to be rectified. The original data was spatially inaccurate, which means that the land use polygons did not align accurately with the aerial photography. Using a technique called "rubber sheeting," all the land parcels were spatially rectified to 90 percent accuracy. The second step in the preparation process was to reclassify the land use data using aerial photography. The original dataset did not have the same classification system or areas that were shown in the comprehensive plan; therefore, the land use was corrected and reclassified. The classifications are: Land Use Classification Commercial Office Parks Commercial Retail Public/Semi-Public Heavy Industrial Right-of-Way/Other Light Industrial Rural Manufactured Homes Single -Family Residential Multi -Family Residential Two -Family Residential Office/Technology Park Vacant Open Space 460611 00 / 030289 4-1 111351 4.2.1 Future Land Use Projections Land use projections for 2020 and 2012 were made using a population to land ratio. The 2000 Comprehensive Plan reported that for an estimated population of 118,792 in year 2020, there would be 7,241 acres of single-family residential. Using this ratio as a criterion, the amount of land in single- family residential for a population of 83,499 (PBSJ estimate) was calculated. The same principle was used for calculating areas for other population -related classifications. Similarly, populations to land ratio projections were made for 2012. For land use types such as light industrial, heavy industrial, and office/ technology park, where the areas are not directly dependent on population, the areas reported in the 2000 Comprehensive Plan were considered accurate for 1999 (and 2020). Areas for 2012 were calculated using the rate of change in areas from 1999 to 2020. Existing and projected land use projections are shown in Exhibits 4.1, 4.2, and 4.3. 4.2.2 Classifying Future Land Use The original data received from the City was attributed to land use classifications for 2020. Since the population estimate for 2020 was revised, the classification areas also changed and the data had to be reclassified to match the numbers obtained from land use calculations for 2020. This process involved using aerial photography and existing attributes in the dataset as a reference. The reclassified land use data was then modified based upon input from the City of Baytown. The same process was adopted for classifying land use for 2012. The land use projections were reviewed by the City, modified where requested, and subsequently approved for use. For determination of utility utilization, classifications were merged into five categories: Single -Family, Multi -Family, Commercial, Light Industrial, and Government. Heavy Industrial was evaluated as a separate category because of its unique requirements. Tables 4.1, 4.2, and 4.3 summarize the merged land use classifications within the City's ETJ for existing, 2012, and 2020. The study and report addresses 36,667 acres of the 85,192 acres in the City's ETJ. The study area is that addressed in the Comprehensive Plan and the area most likely to develop by 2020. The area studied and the total ETJ are shown in Exhibit 4.1. Current, 2012 and 2020 land use projections are shown in Exhibits 4.2, 4.3, and 4.4 respectively. 460611.00 1030289 4-2 1 1 1 1 1 1 1 Table 4.1 Existing Land Usage Land Usage Acres Commercial Office/Retail 1,563.64 Heavy Industrial 3,483.42 Light Industrial 573.00 Manufactured Homes 366.62 Multi -Family Residential 465.94 Office/Technology Park Open Space 63.43 Parks 1,239.31 Public/Semi-Public 1,255.49 Right -of -Way 525.68 Rural 4,143.88 Single -Family Residential 5,595.92 Two -Family Residential 39.13 Vacant 17,352.00 Total 36,667.47 1 460611 00 / 030289 4-3 1 1 1 1 Table 4.2 2012 Land Usage Land Usage Acres Commercial Office/Retail 1,735.22 Heavy Industrial 3,559.16 Light Industrial 416.25 Manufactured Homes 362.83 Multi -Family Residential 517.60 Office/Technology Park 421.24 Open Space 108.82 Parks 1,193.06 Public/Semi-Public 1,347.36 Right -of -Way 500.95 Rural 4,197.55 Single -Family Residential 6,246.27 Two -Family Residential 43.19 Vacant 16,018.00 Total 36,667.47 460611 00 / 030289 4-4 I I I I I I I I I I I I I I I I I I Table 4.3 2020 Land Usage Land Usage Acres Commercial Office/Retail 1,971.90 Heavy Industrial 3,866.16 Light Industrial 539.22 Manufactured Homes 372.60 Multi -Family Residential 549.64 Office/Technology Park 652.34 Open Space 108.82 Parks 1,193.06 Public/Semi-Public 1,377.35 Right -of -Way 491.40 Rural 4,197.56 Single -Family Residential 6,825.96 Two -Family Residential 43.19 Vacant 14,478.28 Total 36,667.47 I 460611 00 / 030289 4-5 4.3 SERVICE AREAS Service and sub -service areas were developed by PBS&J for the City of Baytown. Service and sub - service areas were initially established for wastewater collection and are defined by (1) existing collection system infrastructure that separates it from another service area, (2) geographic conditions that favor collection flowing to a certain location, or (3) undeveloped areas bound by size constraints. Based on the criteria established, the City of Baytown was divided into four major service areas and 1,069 sub -service areas. Once established, the same service areas were used for calculating land use by classification within each sub -service area. Land use within each sub -service area was then used to determine the level of service required for each utility, and those requirements were modeled to determine facility requirements. Existing and projected utility requirements, determined from the areas of each land classification within the sub -service area for each period of study, were converted to equivalent dwelling units ("EDU"), which is a unit of measure defined as the utility requirement for a single-family residential service connection. Utility requirements for multi -family, commercial, industrial, and governmental development were also converted to EDU; therefore, a common/interchangeable unit of measure for utility requirements could be used for all land use classifications. The service and sub -service areas are shown in Exhibit 4.5. 460611 00 / 030289 4-6 2020 Study Area - Baytown ETJ 0 w N a 2.5 5Miles Exhibit 4-1 Baytown ETJ and 2020 Study Area Date: 09/25/03 Prepared By: PBSJ IS Prepared For PBSJ Public Works Group File: N://460611.00/projects/landuse_total_092503.mxd D.la Source Wade Seanandaand ees. earns Pam BvcaNy Sch n and Januar, I. s ▪ c.ne..r Ol.emrr - Menem Pm O M we oic4✓t.ffid.ey Pre r n inViluter.Y ns SeFU0 Rearm..

Water supply is considered to be water wells, water plants, storage, and ancillary treatment facilities, whereas the distribution system consists of distribution booster pumps, pressure maintenance by means of elevated storage tanks, and transmission and distribution line valves and fittings to deliver water from the supply plants. Baytown purchases water from the Baytown Area Water Authority ("BAWA"), which serves as the city's main water supply. The City of Baytown will require additional transmission lines during the study period in order to meet its projected needs. New lines will be needed for developing areas that are not presently served or are underserved. 5.2 EXISTING WATER SYSTEM 5.2.1 City Customers The City of Baytown provides water service to a wide variety of customers. In addition to providing service to the city's residents and commercial developments, Baytown also serves several major industrial customers, including ExxonMobil, Ecolochem, Bayer, and Chevron. Service is also provided to Chambers County Municipal Utility District and Spring Meadows Municipal Utility District. See Table 5.1 for a list of these customers and their respective average daily water demands. 5.2.2 Water Supply BAWA supplies treated water to the City of Baytown. The BAWA plant was completed in 1981 and is currently designed to treat an average daily flow ("ADF") of 13.5 million gallons and a peak daily flow ("PDF") of 19 million gallons. The plant is currently undergoing expansion, and upon completion, will have the capacity to treat an ADF of 19.5 million gallons and a PDF of 26 million gallons. While Baytown is BAWA's largest customer, BAWA also wholesales treated water to several freshwater supply• and municipal utility districts within the area (see Table 5.1). The City of Baytown has six elevated storage tanks: five 500,000-gallon tanks, and one two -million - gallon tank. 5.2.3 Water Distribution BAWA supplies between 70 and 75 psi to Baytown's water distribution system. The plant is located on the northwest side of the city on Thompson Road north of Interstate 10. The plant supplies treated water 460611. 00 1030289 5-1 to the City of Baytown as well as Lake Municipal Utility District, Cedar Bayou Water Co., Inc., Harris County Fresh Water Supply District #27 (Coady), and Harris County Fresh Water Supply District #lA (McNair) via a 30-inch transmission line. A separate transmission line runs north to serve Harris County Water Control & Improvement District #1 and #1-B (Highlands). See Table 5.1 for a list of these customers and their recorded ADF's for 2002. The BAWA-owned 30-inch water line runs east through the City along Lynchburg -Cedar Bayou Road, and turns south along Barkuloo. Reducing to a 24-inch pipe, BAWA's line turns south along the Southern Pacific Railroad and connects with a city -owned 16-inch line at Lobit Avenue. City -owned system piping consists of 1- to 16-inch pipe. Existing pipe materials include iron, steel, asbestos concrete, and plastic pipe. Exhibit 5.1 shows the existing distribution system, which was computer modeled for hydraulic analysis. Only lines 6 inches and larger are considered distribution lines; lines smaller than 6 inches are considered service lines. However, some smaller lines that were considered integral to the distribution system were also included in the model. 5.3 DESIGN CRITERIA 5.3.1 Historical Use City of Baytown historical data was used to develop existing and projected water requirements. The data presented in Sections 3.0 and 4.0 of this report and city water consumption data were analyzed to determine requirement characteristics. City records revealed a total average daily water consumption of 7.90 million gallons per day ("MGD") for the 2001-2002 fiscal year. Calculated consumption for 2003 is 8.26 MGD. The increase in usage is due in large part to the installation of two meters for Spring Meadows Municipal Utility District and one additional meter for Chambers County Municipal Utility District, both in February of 2003. The City of Baytown groups their water and wastewater customers into five classifications: multi -family, residential, governmental, commercial, and industrial. Multi -family includes apartments and multi -unit housing, such as duplex and quadplex units, while residential customers are mainly single-family homes. 5.3.2 State Criteria Texas Commission on Environmental Quality ("TCEQ") criteria, which is specified in TAC, Title 30, Part 1, Chapter 290, Subchapter D, Rules and Regulations for Public Water Systems, 9/13/00, provides minimum acceptable design and construction practices to ensure that facilities are properly sized to produce and distribute a safe potable water. The following criteria is used in this report: 460611 00 / 030289 5-2 Connection - A single residential unit or each commercial or industrial establishment to which drinking water is supplied from the system (§290.38). (Note: The number of connections for 2002 was taken directly from 2002 water billing data. Projected connection counts for 2012 and 2020 were derived using a relationship between the current number of connections and total average daily use for each customer category. Maximum Daily Demand - 2.4 times average daily demand or verified historical data on the system (§290.38). Peak Hourly Demand - 1.25 times maximum daily demand (prorated to an hourly rate), if the system meets the minimum requirements for elevated storage, or 1.85 times maximum daily demand if the system relies on pressure tanks or fails to meet the commission's standards for minimum elevated storage (§290.38). Requirements for Purchased Water Systems (§290.45) - For all systems that purchase treated water to meet all or part of their production, storage, service pump, or pressure maintenance capacity requirements. • The water purchase contract will be available to the commission in order that production, storage, service pump, or pressure rnaintenance capacity may be properly evaluated. A contract is defined by TCEQ as a signed written document of specific terms agreeable to the water purchaser and the water wholesaler, or in its absence, a memorandum or letter of understanding between the water purchaser and the water wholesaler. • The contract will authorize the purchase of enough water to meet the monthly or annual needs of the purchaser. • The contract will also establish the maximum rate at which water may be drafted on a daily and hourly basis. In the absence of specific maximum daily or maximum hourly rates in the contract, a uniform purchase rate for the contract period will be used. • The maximum authorized daily purchase rate specified in the contract plus the actual production capacity of the system will be at least 0.6 gallon per minute per connection. • For systems that purchase water under direct pressure, the maximum hourly purchase authorized by the contract plus the actual service pump capacity of the system must be at least 2.0 gallons per minute per connection or provide at least 1,000 gallons per minute and be able to meet peak hourly demands, whichever is less. • All other minimum capacity requirements will apply (see below). 460611 00 / 030289 5-3 PBSI Minimum Water System Capacity Requirements (§290.45). All surface water supplies must provide the following: • Raw Water Pump - Capacity of 0.6 gallon per minute per connection with the largest pump out of service. • Treatment Plant - Capacity of 0.6 gallon per minute per connection under normal rated design flow. • Transfer Pumps (where applicable) - Capacity of 0.6 gallon per minute per connection with the largest pump out of service. • Covered Clearwell - Storage capacity at the treatment plant of 50 gallons per connection, or for systems serving more than 250 connections, 5.0 percent of daily plant capacity. • Storage - Total capacity of 200 gallons per connection. Elevated capacity of 100 gallons per connection is required for systems with more than 2,500 connections. • Service Pump - For systems which provide an elevated storage capacity of 200 gallons per connection, two service pumps with a minimum combined capacity of 0.6 gallon per minute per connection are required at each pump station or pressure plane. • Emergency Power - Required for systems that serve more than 250 connections and do not meet the elevated storage requirement. • Nominal Operating Pressure - 35 psi throughout system; 20 psi minimum during firefighting. 5.3.3 City Criteria City of Baytown criteria for general benefit water utility systems is as follows: • Maximum day velocity in lines is 5 feet per second. • Fire flow for residential areas is 750 gpm. • Fire flow for commercial areas is 1,500 gpm. • Line capacity should consider a peak day domestic use plus fire flow. • A water line 12 inches and larger qualifies as a general benefit utility. 460611 00 / 030289 5-4 5.4 EXISTING REQUIREMENTS Water demand is based on existing land use and density and the criteria as set forth in Section 5.3. Tables 5.3 and 5.4 show water requirements of Baytown customers for 2003. Table 5.3 shows demand by land use type, and Table 5.4 breaks demand down by service area. Average day demand was calculated to be 8.26 MGD, with 33,045 total EDU's. An EDU is used to relate developments of different sizes to single-family home dwelling as the base standard. Records show that the average single-family home uses approximately 250 gallons per day ("gpd"), therefore defining a water system EDU as 250 gpd. As mentioned in Section 5.3.2, TCEQ design criteria is based on the number of connections rather than number of EDU's. The City currently provides water service to approximately 15,000 connections. 5.4.1 Adequacy of Existing System The existing water system was evaluated against TCEQ criteria. Because Baytown purchases water from BAWA, they must meet the "Purchased Water System" requirements as listed in the previous section. Baytown's contract with BAWA states that BAWA will not be obligated to deliver to the city treated water in excess of the contract quantity of a monthly average per day of 10.71 MGD. BAWA supplies water under direct pressure, usually between 70 and 75 psi. For systems under direct pressure, TCEQ requires the sum of the contracted maximum hourly purchase and the actual service pump capacity to be at least 2 gallons per minute per connection. However, the contract does not specify a maximum hourly purchase, and it is assumed that water will be available to Baytown as needed during peak hours. The current contract is a 1996 amendment to the original 1977 contract with BAWA and is effective through December of 2020. Water supply, storage, and pumps are required to have minimum capacities based on connections and the delivery of minimum pressures. All system elements currently meet TCEQ minimum criteria. Below is a summary of existing and TCEQ required supply components for 2003 based on 15,300 connections. TCEQ Requirements for City BAWA Plant Raw Water Pump Capacity 9,180 gpm 20,850 gpm Treatment Plant Capacity 9,180 gpm 18,056 gpm Transfer Pump Capacity 9,180 gpm 18,000 gpm Clearwell Capacity 975,000 gal 13,500,000 gal Service Pump Capacity 9,180 gpm 18,000 gpm Emergency Power * 18,000 gpm 460611 00 / 030289 5-5 TCEQ ' Requirements City of Baytown Elevated Storage 1,530,000 gal 4,500,000 gal Total Storage 3,060,000 gal 4,500,000 gal The ability of both the supply and distribution systems to meet pressure requirements was evaluated by a ' computer model of the existing demands. The results showed that the existing distribution system is capable of maintaining pressures required by TCEQ for average daily flows, as well as emergency fire flows, for 2003. See Exhibits 5.3 and 5.4 for year 2003 pressure contours. 5.5 PROPOSED IMPROVEMENTS 2012 5.5.1 Demand Requirements ' The requirements for 2012 were determined from land use and density projections developed in chapter 3. As mentioned in Section 5.2, BAWA serves several municipal and county districts. Future requirements are based on the premise that during the study period existing municipal utility districts ("MUD's") in the ' ETJ will be served utilities and/or annexed by the City, and if other areas need to be served, the City will do so. Districts assumed to be provided City service are those currently receiving service from the ' 30-inch BAWA line that serves Baytown (Lake Municipal Utility District, Harris County Fresh Water Supply District #27 [Coady], and Harris County Fresh Water Supply District #1A [McNair]). (Note: Demands for these districts were not included in the stated 2003 demands for Baytown; however; they iwere applied to the water model at their appropriate locations). Projected water demands for the city and the above -stated freshwater and municipal utility districts for 2012 are shown in Table 5.3. Average day ' demand is projected to be 10.21 MGD, and EDU's are calculated to be 40,837 at 250 gpd/EDU. Connections are calculated to be approximately 19,100. ' Below is a summary of existing and TCEQ required supply components for 2012 based on 19,100 connections.

The City is planning to build a 1 million -gallon elevated storage tank at the corner of Main and Garth before the year 2012. While the existing elevated storage total capacity of 4.5 million gallons meets TCEQ requirements for 2012, the proposed tank will assist in maintaining pressure in the area, as well as provide additional storage for future growth. Growth projections and computer analyses indicate additional transmission lines are necessary. BAWA plans to install a 30-inch transmission line from the BAWA plant along Thompson Road north to Wallisville Road, east along Wallisville to Sjolander, then south along Sjolander to the existing 12-inch water line along IH 10. BAWA plans to have this line installed and functioning by 2008. Several developments along Wallisville will require water prior to the installation of the BAWA line. Installation of a 12-inch line along John Martin Drive from the 12-inch water line along IH 10 to Wallisville is recommended. This line will provide service to MUD 213, as well as provide additional circulation between Baytown's system and the new BAWA line. An existing 12-inch water line extends along Garth Road from IH 10 to Harbor Mist. It is recommended to extend this line to connect with the new BAWA line along Wallisville. It is also recommended to construct a 16-inch line along North Main from IH 10 to Wallisville Road. Goose Creek Independent School District plans to build a new school at the corner of Wallisville and North Main within the next five years, and this line will be needed to provide water service. Development is projected along Archer Road between Garth and Sjolander, and installation of a 16-inch water main is recommended. Finally, replacement of a 6-inch with a 16-inch water line along N. 6th Street from E. Lobit to E. Defee Avenue is also recommended for improved circulation. The proposed projects for 2012 may be seen on Exhibit 5.2. Exhibits 5.5 and 5.6 show the pressure contours associated with the improved system and water demands for 2012. 5.5.3 Cost Estimates The cost estimates presented here are preliminary and final costs may vary. These costs include a contingency factor and allowance for design fees (35 percent). The costs do not include allowances for 460611 00 / 030289 5-7 legal or fiscal costs. The probable costs are based on current -year dollars and average unit costs. The cost of a 10-year water system CIP is estimated to be $3,281,200. A project cost breakdown is shown in Table 5.4. 5.6 PROPOSED IMPROVEMENTS 2020 5.6.1 Demand Requirements The requirements for 2020 were determined using the methods mentioned in Section 5.5 for 2012. Projected water demands for the city and ETJ for 2020 are shown in Tables 5.3 and 5.4. Average day demand is projected to be 11.21 MGD, and EDU's are calculated to be 44,900 at 250 gpd/EDU. Connections are calculated to be approximately 21,100. Below is a summary of existing and TCEQ required supply components for 2020 based on 21,100 connections.

PROPOSED PROJECTS 6.0 WASTEWATER MASTER PLAN 6.1 GENERAL The Baytown wastewater collection system is made up of a network of gravity lines and lift stations with force mains, all flowing to one of three wastewater treatment plants ("WWTP's"), with a fourth WWTP currently in the design phase. The city has some topographic relief, primarily toward Goose Creek and Cedar Bayou. The wastewater drainage system is divided into four districts: Northeast, East, Central, and Northwest. Based on information provided by the City of Baytown and the projected land use data, the existing wastewater system was evaluated for current, 2012, and 2020 flow conditions. It was through this analysis that candidate projects for both expansion and rehabilitation of the wastewater collection system were identified and presented to City of Baytown representatives for consideration and inclusion in their CIP. 6.2 EXISTING WASTEWATER SYSTEM The existing wastewater system can be separated into several major categories in servicing the City of Baytown customers: gravity collection lines, lift stations and their associated force mains, and wastewater treatment plants. 6.2.1 Customers The City of Baytown provides wastewater service to all residences and most businesses within the city limits. Not included in this, however, are heavy industrial users such as Exxon in the southwest and Chevron and Huber in the northeast who provide their own wastewater disposal. Several MUD's outside the city limits are also served by their own wastewater system. A list of clients and means of wastewater service is noted in Table 6.1. 6.2.2 Wastewater Treatment Plants The City currently operates three WWTP's. The East District Plant was originally constructed in 1965, with an estimated design capacity of 1.0 MGD, using contact stabilization. In 1976, it was enlarged to 3.0 MGD, still as a contact stabilization plant. In 1995, a 1.5-MGD complete mix expansion was constructed, increasing the plant capacity to 4.5 MGD. Finally, in 2000, an additional 1.5 MGD complete mix expansion was added, bringing the total permitted capacity to 6.0 MGD (3.0 MGD contact stabilization, 3.0 MGD complete mix). There is no potential for increased capacity at this plant. Influent Pump Station 1 for the plant has four Gorman Rupp pumps (one 6-inch at 700 GPM, two 8-inch at 1800 460611 00 / 030289 6-1 PBEI GPM each, and one 8-inch at 1200 GPM) and one Flygt pump (8-inch at 3000 GPM). Influent Pump Station II is new and houses all Gorman Rupp pumps (one 6-inch at 700 GPM, one 8-inch at 1400 GPM, one 10-inch at 2100 GPM, one 12-inch at 2800 GPM, and two 12-inch at 3500 GPM each). The West District Plant was constructed in 1981 with a capacity of 1.62 MGD (complete mix). It was enlarged in 1993 to its current permitted capacity of 4.0 MGD and has a potential ultimate capacity of 8.0 MGD. It has one influent pump station with all submersible Gorman Rupp pumps (one 6-inch at 380 GPM, one 8-inch at 1000 GPM, two 8-inch at 1100 GPM each, and two 12-inch at 5500 GPM each). The original construction date for the Central District is estimated to be 1960 with a 0.7-MGD capacity. In 1967 it was enlarged to 1.7 MGD, all contact stabilization. In 1974 it was again enlarged to 3.5 MGD, all complete mix. Finally, in 1988 it was enlarged to its current permitted capacity of 6.2 MGD (complete mix). There is no potential for increased capacity at this plant. The influent pump station contains three Allis Chalmers vertical mount pumps (one 14-inch at 7600 GPM and two 18-inch at 8450 GPM each). A fourth WWTP, the Northeast District Plant, is currently in the planning and design phase with a capacity of 4.0 MGD and a site capacity of up to 12.0 MGD. Construction on this plant is expected to commence in 2005. 6.2.3 Wastewater Collection System 6.2.3.1 Lift Stations The City of Baytown currently operates 19 major lift stations and more than 50 smaller ones. The major lift stations and their capacities are shown in Table 6.2. In evaluating the existing lift stations, several meetings were held with representatives from the City of Baytown. In these meetings, the existing and future capacity of the lift stations was discussed. Pending new construction and improvements to existing facilities were also noted and compiled. Through this data and our modeling of wastewater requirements within their service areas, each lift station was evaluated for existing, 2012, and 2020 conditions. 6.2.3.2 Gravity Collection Systems Exhibit 6.1 shows the existing sewer system along with location of WWTP's and lift stations. The existing condition of the pipe and manholes in the field were not investigated during the course of the study. With the trunkline sizes known, an indication from City of Baytown officials as to "problem areas," and assumed minimum grade on the lines, the system was evaluated for existing and future capacity. The City also provided information regarding future planned rehabilitation, primarily pipe - bursting, which was accounted for while considering the impact of inflow and infiltration ("I/I") on the system. 460611.00 / 030289 6-2 6.3 DESIGN CRITERIA Proposed wastewater collection and treatment requirements were determined from land use projections and the use of historical wastewater flow data. The wastewater demands for each category of land use are approximately 80 percent of water demands. TCEQ criteria is used wherever applicable. Peak (wet weather) flows are presumed to be 300 percent of average day flow rates to the WWTP's and 400 percent of the average day flow rates for the collection system. The layout of collection lines is such to provide flexibility toward future land use changes and economic considerations. Maximum sewer capacities were calculated for pipes flowing full at not less than 2 feet per second using standard grades based on Manning's formula with an assumed "n" factor of 0.013. The construction of a lift station is proposed when expensive gravity trunklines get too deep or are not yet financially justified. In order to avoid under -designs, which can occur without long-range planning, trunkline sizes were based upon consideration of the size of an area and an allowance for full development. The interim improvements for the study period consider future growth and provide a base system for ultimate improvements. Criteria used for General Benefit Utilities (GBU) for Impact Fees was established for utility lines (12-inch and larger) serving more than 250 residential acres (or 900 EDU's), and for lift stations serving 500 residential acres (or 1,700 EDU's). Lift stations sized and capable of serving 1,700 EDU's required a minimum 1,500 GPM firm pump capacity and 10-foot diameter well. Force mains 10 inches and larger were also considered qualifying. Three primary pieces of information comprised the key elements to evaluating the existing system and the need for future expansion and relief: estimated wastewater usage, estimated I/I, and historical data such as manhole and lift station overflows. 6.3.1 Base Wastewater Flow As noted in Section 5.0, water usage was estimated to be 250 gpd per EDU ("GPED"). Since wastewater production is typically estimated at 80 percent of this water usage, 200 GPED was used as the base amount throughout the system analysis. 6.3.2 I/1 Contribution I/1 is the admittance of water into the wastewater collection system that must be transported and ultimately treated. Infiltration comes primarily from groundwater that enters the collection system through leaking joints and taps. Inflow comes primarily from stormwater that enters the collection system in a variety of ways, including submerged or leaky manholes, open cleanouts, illegal taps, and leaky joints. I/1 contribution to the system on a daily basis was estimated by comparing the total flow to each of the WWTP's derived from the model to the actual flow reported on a daily basis. That is, the average 460611 00 / 030289 6-3 PBSI non -peak daily flow estimated to be produced by each of the four categories of dwellings was subtracted from the actual average daily flow on days where no rain was reported. This daily non -rainfall event U1 was then added to the model on a weighted scale based on the distribution of EDU's per acre for each of the dwelling classifications. The 2002 ADF UI was calculated to be 4.67 MGD. For projection of system -wide wastewater flow in the future, it was important to incorporate into the model the City's ongoing efforts to reduce VI. Using information provided by the City, this 2002 non - rainfall UI was reduced by 50 percent for 2012 projections in sub -service areas where construction such as pipebursting, sliplining, and insituform is currently planned. Assuming the City continues the 1/1 reduction program and new construction produces zero 1/1, the estimated reduction of 2002 Ul in 2020 was 50 percent system -wide. Inflow allowances are accounted for through the peaking factors that are applied. 6.3.3 Historical Data The City of Baytown provided WWTP flow data for the past several years. This data also included rainfall information and copies of overflow reports for the past several years. Once compiled, this information highlighted a few specific areas where further scrutiny was warranted when the original wastewater model did not already indicate deficiencies in the system. 6.4 EXISTING REQUIREMENTS Wastewater demand is based on existing land use and criteria as set forth in Section 5.3. Table 6.3 shows the wastewater demand by subsection for 2002, the beginning of this study. 6.4.1 Adequacy of Existing Systems 6.4.1.1 Treatment Plants The City operates three wastewater treatment plants: The West District Plant has a permitted capacity of 4.0 MGD and has a 2002 ADF of 2.70 MGD. The Central District Plant has a permitted capacity of 6.2 MGD and has a 2002 ADF of 3.85 MGD. Finally, the East District Plant has a permitted capacity of 6.0 MGD and has a 2002 ADF of 4.79 MGD. All current ADF's are within their permitted capacities. A fourth treatment plant to be constructed in the northeast part of the city will have a permitted capacity of 4.0 MGD. 6.4.1.2 Lift Stations Most existing major lift stations are adequate to serve the existing demands as shown in Table 6.2. While overflows have been experienced at or near four different lift stations, most of these problems are already being addressed. Several reports of overflows near Lift Station No. 35 were reported in 2002. This problem is expected to be resolved through the construction of the Big Missouri Lift Station and new PliSi 460611.00 / 030289 6-4 force main. Scheduled pipebursting projects in the area of Greenbriar/Steinman and Cedar/Elton should resolve issues near Lift Station Nos. 58 and 66. 6.4.1.3 Gravity Collection Systems Most existing collection lines are adequate to serve the existing demands. The primary concern regarding existing lines, however, is VI. While our models indicate a base -flow from wastewater customers at 6.66 MGD, the combined average daily flow for all three WWTP's is 12.49 MGD, the remainder resulting from non -rainfall infiltration (4.67 MGD) and inflow during peak events. As previously mentioned, the City is currently undergoing a comprehensive rehabilitation program to reduce VI, simultaneously increasing the capacity of many of the lines through pipebursting. 6.5 PROPOSED IMPROVEMENTS 2012 For 2012 projections, we took the conservative approach of assuming that all non -industrial areas developing within the ETJ may be receiving wastewater service from the City. 6.5.1 2012 Demand Requirements The treatment requirements for 2012 were determined from land use and density projections within the City's ETJ for the study period. The projected 2012 wastewater demands for the city and ETJ are shown in Table 6.3. At that time, we anticipate that the City will be treating an average of 12.36 million gallons of wastewater each day. 6.5.1.1 Treatment Plants In 2012, the Central District Plant will be receiving 4.19 MGD, the West District Plant will be receiving 3.16 MGD, the new Northeast District Plant will be receiving 1.31 MGD, and the East District Plant will be receiving 3.69 MGD. All plants are shown to be safely within their permitted capacities, since approval of the 2012 Land Use Map, several developers have expressed a significant amount of interest in developing the northwest part of the city. This unexpected development will increase demand on the West District Treatment Plant such that an expansion is warranted. 6.5.1.2 Lift Stations Lift Station No. 47 may become an area of concern by 2012. As shown in Table 6.2, Lift Station No. 47, with a firm capacity of 1300 GPM, has a 2012 peak flow (peak factor of 4.0) of 1330 GPM. 6.5.1.3 Gravity Collection Systems PBS&J performed an analysis of the primary trunklines and determined deficiencies in the system due to age and size warrant certain relief routes. One particular line in the Central District, however, was an area of concern. The 15-inch line along Park St. south of Lift Station No. 43 has a theoretical capacity of 460611.00 / 030289 6-5 PBS; 1130 GPM and is currently undersized for the expected 2012 flow of 2045 GPM. A relief route should be constructed by which the existing 15-inch line is both upsized and diverted via a new line along Memorial Drive directly to Lift Station 41. 6.5.2 System Improvements A new WWTP in the northeast part of the city is planned for construction in the very near future with a permitted capacity of 4.0 MGD. Also, as noted earlier, developers' interest in the northeast part of the city has resulted in an increased future demand on the West District WWTP. Accordingly, an expansion of the West District WWTP of 4.0 MGD is recommended. Lift Station No. 47 may need to be upgraded by increasing the capacity of the pumps. In addition, the recently -constructed Lift Station No. 75 will require modifications as it is used to redirect the Pinehurst area flow from the East District to the newly constructed Northeast District Plant. The current force main serving this lift station will be converted to a gravity line and the direction of flow reversed per its original design. This lift station was designed with this sort of flexibility in mind and will require a new force main (8,500 feet) located roughly parallel to the Southern Pacific Railroad corridor. Diverting this flow will also provide relief to the existing lines flowing south to the East District Plant. Three new trunklines are proposed for the northeast section as the new WWTP comes on-line, including a stub under 1TI 10 for future growth. As shown in Exhibit 6.2, approximately 52,000 linear feet of new sanitary trunklines to provide relief to existing lines in the Central District and service to new development areas annexed in the other districts. Table 6.4 indicates size and length for each of these lines. Although it's impossible to predict with any high degree of accuracy the exact location or year in which the lines will be needed, the CIP provides a plan which can be periodically reviewed in order to develop construction schedules consistent with actual growth trends. In all cases, right-of-way for the proposed improvements should be obtained to facilitate carrying out the program. 6.5.3 2012 Cost Estimates The cost estimates presented in Table 6.5 are preliminary; final costs may vary. Probable construction costs for proposed improvements include basic items plus appurtenances, as well as allowances for engineering and contingencies. The costs do not include allowances for private crossings, legal or fiscal costs, or right-of-way. The probable costs are based on current -year dollars and average unit costs. 6.6 PROPOSED IMPROVEMENTS 2020 For 2020 projections, we again took the conservative approach of assuming that all developing areas within the ETJ may be receiving wastewater service from the City. 6-6 PBS; 460611.00 / 030289 t 6.6.1 2020 Demand Requirements The treatment requirements for 2020 were determined from land use and density projections for the study period. The ETJ is included as part of the study area for 2020 projects. The projected wastewater ' demands for the city and ETJ by sub -section are shown in Table 6.3. At that time we anticipate that the City will be treating an average of 11.3 million gallons of wastewater each day. It is important to note ' that while the 2012 ADF is greater than the 2020 ADF, this is a direct result of PBS&J's assumption that the City of Baytown will continue ongoing I/I reduction efforts through 2020. These efforts are reflected in our study with the assumption that by 2020, the current amount of I/I the system experiences will be ' reduced by 50 percent. 6.6.1.1 Treatment Plants ' The Central District Plant will be receiving 3.44 MGD, the West District Plant will be receiving 3.46 MGD, the new Northeast District Plant will be receiving 1.34 MGD, and the East District Plant will be receiving 3.05 MGD. All plants should be safely within their permitted capacities and no further treatment plant expansions are recommended during the study period. ' 6.6.1.2 Lift Stations ' Lift Station No. 63 is projecting a dramatic increase in peak flow by 2020. With a firm capacity of 3300 GPM, projections for 2012 (3225 GPM) brought some concern, but projections for 2020 (3540 GPM) certainly warrant corrective measures. 6.6.1.3 Gravity Collection Systems PBS&J performed an analysis of the primary trunklines and determined that while the system has enough theoretical capacity to handle the demands, likely deficiencies in the system due to age warrant certain relief routes. In the Central District, the 21-inch line along Goose Creek (north of Rollingcreek Drive) has a theoretical ' capacity of 2144 GPM and a 2012 peak flow of 2357 GPM. The downstream end of this trunkline, where the bulk of the system is collected in a 30-inch line before discharging into the WWTP, the theoretical capacity is 4340 GPM and the 2012 peak flow is anticipated to be 6755 GPM. Both of these lines will receive initial relief from new lines C-4 and C-5 by 2012, but would further benefit from a relief route along State Highway 146. 6.6.2 System Improvements Approximately 75,000 linear feet of new sanitary trunklines are shown in Exhibit 6.3 to provide relief to ' existing lines in the Central District, and service to new development areas annexed in the other districts. Table 6.6 indicates size and length for each of these lines. Although it's impossible to predict with any 460611 00 / 030289 6-7 1 high degree of accuracy the exact location or year in which the lines will be needed, the CIP provides a plan which can be periodically reviewed in order to develop construction schedules consistent with actual growth trends. In all cases, right-of-way for the proposed improvements should be obtained to facilitate carrying out the program. 6.6.3 Cost Estimates As noted in Section 6.5.3, the cost estimates presented in Table 6.7 are preliminary. Final costs may vary. 460611.00 1030289 6-8 Table 6.1 CITY OF BAYTOWN MASTER PLAN WASTEWATER CUSTOMERS SERVED Client ADF Committed (GPD) MUDs Chambers County MUD No 1 207,200 HCMUD No 3 412,000 San Jacinto Place MUDs No 1,2,3 & 4 (annexed into City 1999) HCFWSD No 1_A 350,000 Spring Meadow MUD 550,000 Thompson Road UD 692,700 HCFWSD No 27 130,000 Industry US Filters 44,000 MUDs (not served) HCMUD 50 HCMUD 80 HCMUD 213 Cedar Bayou MUD Industry (not served) Exxon Olefins Exxon Co USA Gulf Oil Ind Dist 2 Huber Corp Ind Dist 2 11/3/032:49 PM Page 1 of 1 Land Use - Waste Water (revised).xls LS PF WWTP PF 4.00 3.00 Table 6.2 CITY OF BAYTOWN MASTER PLAN WASTEWATER LIFT STATION DEMANDS Existing I- 2012 2020 Firm LS Capacity EDU's AVERAGE DAILY FLOW (ADF) PEAK FLOW AVERAGE DAILY FLOW (ADF) PEAK FLOW EDU's AVERAGE DAILY FLOW (ADF) PEAK FLOW ADF Non -Rain (MGD) I/I (MGD) Total ADF (MGD) Total ADF (GPM) PDF (MGD) PDF (GPM) EDU's Non- ADF Rain I/1 Total ADF Total ADF (MGD) (MGD) (MGD) (GPM) PDF (MGD) PDF (GPM' ADF (MGD) Non- Rain I/1 (MGD) Total ADF (MGD) Total ADF (GPM) PDF (MGD) PDF (GPM) 3 1600 1907.21 0.38 0.21 0.59 409.43 2.36 1637.70 1953.28 0.39 0.12 0.51 351.64 2.03 1406.56 1968.23 0.39 0.10 0.50 345.63 1.99 1382.53 4 3000 229.01 0.05 0.04 0.08 56.64 0.33 226.57 232.04 0.05 0.04 0.08 57.06 0.33 228.25 232.72 0.05 0.02 0.06 44.74 0.26 178.98 12 2000 2776.20 0.56 0.26 0.81 564.98 3.25 2259.91 1749.29 0.35 0.24 0.59 410.91 2.37 1643.64 1786.71 0.36 0.13 0.49 337.85 1.95 1351.41 14 25000 4309.29 0.86 0.60 1.46 1014.24 5.84 4056.95 4352.78 0.87 0.56 1.43 992.09 5.71 3968.37 4979.87 1.00 0.30 1.30 899.51 5.18 3598.04 21 1800 1025.49 021 0.18 0.38 265.34 1.53 1061.35 937.86 0.19 0.18 0.36 253.16 1.48 1012.66 978.82 0.20 0.09 0.28 197.40 1.14 789.60 27 1600 202.49 0.04 0.03 0.07 48.46 0.28 193.84 200.47 0.04 0.03 0.07 48.18 0.28 192.72 641.03 0.13 0.01 0.14 99.20 0.57 396.80 30 1250 86.57 0.02 0.08 0.10 67.57 0.39 270.30 1441.48 0.29 0.07 0.35 245.54 1.41 982.17 1753.37 0.35 0.04 0.39 271.30 1.56 1085.20 35 1760 932.34 0.19 0.15 0.33 230.96 1.33 923.86 1038.54 0.21 0.07 0.28 194.98 1.12 779.91 1038.54 0.21 0.07 0.28 194.98 1.12 779.91 37 1360 188.34 0.04 0.03 0.07 45.97 0.26 183.86 194.74 0.04 0.03 0.07 46.85 0.27 187.42 194.74 0.04 0.01 0.05 36.95 0.21 147.80 41 11000 3307.87 0.66 0.47 1.13 785.90 4.53 3143.60 3654.76 0.73 0.39 1.12 780.84 4.50 3123.36 3698.44 0.74 0.24 0.97 676.91 3.90 2707.63 43 6800 3016.14 0.60 0.30 0.90 628.24 3.62 2512.96 3097.55 0.62 0.30 0.92 639.55 3.68 2558.19 3055.86 0.61 0.15 0.76 529.09 3.05 2116.36 47 1300 1583.91" 0.32 0.19 0.51 351.54 2.02 1406.16 1724.25 0.34 0.19 0.53 371.03 2.14 1484.13 1724.12 0.34 0.09 0.44 305.24 1.76 1220.95 49 1600 547.05 0.11 0.07 0.18 123.60 0.71 494.39 559.39 0.11 0.07 0.18 125.31 0.72 501.24 559.39 0.11 0.03 0.15 101.50 0.58 406.00 50 1800 677.26 0.14 0.08 0.22 149.85 0.86 599.42 1021.93 0.20 0.08 0.28 197.73 1.14 790.90 1067.97 0.21 0.04 0.25 176.22 1.02 704.90 51 6000 847.41 0.17 0.09 0.26 183.04 1.05 732.17 444.42 0.09 0.09 0.18 127.07 0.73 508.28 934.27 0.19 0.05 0.23 162.43 0.94 649.73 58 2600 396.71 0.08 0.06 0.14 98.09 0.56 392.36 753.88 0.15 0.06 0.21 144.49 0.83 577.94 748.68 0.15 0.03 0.18 125.48 0.72 501.91 63 3300 1752.50 0.35 0.25 0.60 413.70 2.38 1654.78 4398.70 0.88 0.25 1.12 781.22 4.50 3124.89 5930.73 1.19 0.12 1.31 908.86 5.24 3635.43 66 3000 2942.34 0.59 0.38 0.96 669.88 3.86 2679.51 3177.94 0.64 0.33 0.97 671.82 3.87 2687.27 3254.17 0.65 0.19 0.84 582.58 3.36 2330.31 67 1600 173.17 0.03 0.03 0.06 43.95 0.25 175.78 288.68 0.06 0.03 0.09 59.99 0.35 239.95 272.71 0.05 0.01 0.07 47.82 0.28 191.29 Central WWTP 11712.65 2.34 1.51 3.85 2673.28 11.55 8019.83 12774.38 2.55 1.6.1 4.19 2909.83 12.57 8729.49 13011.57 2.60 0.84 3.44 2391.03 10.33 7173.10 West WWTP 7804.07 1.56 1.13 2.70 1871.92 8.09 5615.77 10459.60 2.09 1.07 3.16 2194.00 9.48 6582.01 12741.34 2.55 0.91 3.46 2404.97 10.39 7214.91 Northeast WWTP 0.00 0.00 0.00 0.00 0.00 0.00 0.00 3688.49 0.73 0.58 1.31 912.09 3.94 2736.26 4788.99 0.96 0.38 1.34 927.21 4.01 2781.64 East WWTP 13799.43 2.76 2.03 4.79 3328.41 14.38 9985.23 10865.65 2.17 1.52 3.69 2565.23 11.08 7695.68 11320.14 2.26 0.79 3.05 2121.17 9.16 6363.52 Total WWTP 33316.15 6.66 4.67 11.34 7873.61 34.01 23620.831 37768.12 7.55 4.80 12.36 8581.15 37.07 25743.45 41862.04 8.37 2.92 11.30 7844.39 33.89 23533.17 • - Overflows reported at Lift Station or nearby Manhole.

City Engineer City of Baytown 2401 Market Street Baytown, Texas 77522-0424 Dear Mr. Pedersen: PN 460611.00 Re: Water and Wastewater Master Plan through 2020 and Capital Recovery Fee Determination: Baytown City Ordinance No. 9392 Our contract scope of work called for review of the City's existing Comprehensive Plan prepared by Wilbur Smith and to use their population projections and land use projections as the basis of our development of the Master Plan and Capital Recovery Fee (CRF) Study and Report. Population projections and land use are the basis for development of the master plans and CRF in that they dictate the size and location of utilities which need to be built to support new development and the exaction of fees from developers to pay for the utilities which must be built. Without acceptable projections on how much and where development will take place, the remainder of the report becomes questionable and unsupportable. Enclosed is an interim report on our analysis of population projections made in the Baytown 2000 Comprehensive Plan (The Plan). We do not believe that the projections made in it are supportable and believe that they need to be revised for our contract. The disparity between The Plan's population projections and our findings is so significant that the land use projections in The Plan, which we intended to use as a basis for our study, are now also questionable and will need to be completely revised. It is imperative that agreement be reached on population projections and land use assumptions before we can proceed with development of the utility master plans. Chapter 395 of the Texas Local Government Code requires that City Council approve land use assumptions and master plans before a CRF can be established. 1880 S.

Vice President DC:kls 460611.00 Interim Report Population Projections City of Baytown Utility Master Plans 2020 and CRF Determination The Baytown 2020 Comprehensive Plan (The Plan), Chapter 3, Community Profile provides discussion and projection of the City's population through 2020. Table 3.1, Historical and Estimated Population, Baytown and Harris County which is taken from The Plan is presented in Attachment 1 for reference. This table shows that the Baytown 1990 population was 63,850 and the estimated 1998 population was 70,412. The table show a 7.7% increase in population over that 8 years; however, the change calculates to be 10.3 %. The published 2000 census figures for Baytown shows the actual population at that time to be 66, 430. This population increase is actually 4.0% over the ten-year period 1990 to 2000. The Plan tries to analyze the growth projections of the Texas State Data Center (TSDC), but the TSDC does not compile data for municipalities such as Baytown. Further, The Plan tries to draw some parallel between the growth of Harris County and the City; however, there is little correlation between the two except there has been a general decrease in the rate of population growth in both since 1950. Without any explanation, The Plan selects Baytown's projected population increases using a constant growth rate of 2.4% per year, which was based on the rate of growth of the City between 1950 and 1998. This rate of growth resulted in projections of 94,630 persons in 2010 and 118,792 persons in 2020. As indicated earlier, the City's rate of growth has decreased in recent years. Between 1980 and 1990, the City grew at an annual rate of 1.2 percent and between 1990 and 2000 the City grew at an annual rate of 0.4 percent. Houston -Galveston Area Council (HCAC) makes population forecasts for Regional Area Zones (RAZ) in Harris County (Attachment 2). HGAC projections are based on the relocation of people into Hams County, transportation forecasts, government and real estate information, and land use criteria and census tract information. The RAZ do not necessarily correlate to city boundaries but are small enough to draw a good correlation. Baytown is in three RAZ, 85, 86 and 88. By using the difference between 2000 City census and the 2000 HGAC number, an estimate can be made of their projections for the Baytown area. Using HGAC projections, the City's population would be 68,428 persons in 2010 and 74,003 persons in 2020. The Texas Water Development Board (TWDB) has also developed projection for Municipalities as part of the statewide water planning program (Attachment 3). The TWDB projections are based upon historical population and anticipated number of water permits. The values provided were for the 2002 State Water Plan, which did not have the 2000 census data. The TWDB grossly over estimated Baytown's 2000 population and showed it to be 80,949 as compared to the census number of 66,430. If the projections are adjusted using the 2000 census data as a starting point, we see that the 2010 population is projected to be 76,028 persons and the 2020 population will be 88,115 persons. If the City were to continue growing at the rate experienced between 1990 and 2000, its population would be 69,135 persons in 2010 and 71,951 persons in 2020. Should the City continue to grow at the rate experienced between 1980 and 1990, its population would be 74,477 persons in 2010 and 83,499 persons in 2020. Because of the City's annexation plans and development initiatives, growth can be expected to be greater than the 1990 to 2000 period; however, there is no reason to expect the growth rate should exceed that of the 1980 to 1990 period. We consider The Plan's projections as well as those of the TWDB to be extremely high. Perhaps a compromise between the TWDB and the HGAC are a good target. We recommend that the average growth rate of the 1980 to 1990 be considered. This rate is 1.2 percent per year or about one half of that used in The Plan. This growth rate results in a projected population of 74,477 persons in 2010 and 83,499 persons in 2020. Some of the population projections discussed are shown graphically in Figure 1 so they can be compared. Our projections result in a significantly different population estimate than that of the Baytown 2000 Comprehensive Plan and radically changes the projected 2020 land use assumptions. Likewise the utility requirements to support these lower populations will be significantly different and can affect Capital Recovery Fees that will be required.
