1. PLAN HISTORY
The City of Katy's first Comprehensive Plan was developed in 1969 by Robert W. Caldwell and Associates, Inc. of Bryan, Texas. The 1969 plan was the result of five years of work by the planning consultant, the City of Katy's administration, planning committee and the zoning committee. A subdivision ordinance at developed that time is still in use while the Zoning Ordinance that was a by-product of the plan was rejected by Katy voters.
In 1979, the City of Katy authorized its consulting engineering firm, O'Malley & Clay, Inc. to update the to reflect the and events plan changes of the past decade. The second comprehensive plan was completed in 1980 and was revised to reflect zoning which was voted in by the voters of Katy in 1983.
2. BACKGROUND
After completion of the 1980 Comprehensive Plan, there were a number of occurrences that could not have been anticipated. The major event that changed the growth pattern in the Katy-West Houston area was a world-wide recession. The recession started early in most parts of the U.S. but did not in the area until peak Katy 1984. For several years afterward, the Katy area, along with the majority of the Houston area, lost population. Development patterns changed in Katy because of the recession. Zoning was voted in by the Katy voters in 1983 which also effected development patterns in Katy.
3. EXPECTATIONS
There are several events of the late 1990's that will continue to influence the City of Katy's development for decades. Included in these are the items described below: a. The Katy Mills Mall and outparcel development. b. Interest in the Katy area by light industry. c. Master drainage plan for the City of Katy. d. Interest by potential homeowners to relocate to the Katy Independent School District
Page -1- 4. THE COMPREHENSIVE PLAN
This Plan for Katy is intended as a documentary guide for the orderly and desirable physical development of the City and its planning area for a period of two or more future decades. It is not meant to be stringently binding, but sufficiently flexible to the extent that adjustments can be made to absorb changes in community characteristics and technological advances in physical urban development processes. The total planning program represented in this Plan investigates and analyzes the planning area, determines such problems as may now exist, develops the planning objectives, and presents proposals for correction and alleviation of the problems found. The Plan considers, among other things, the following:
a. An inventory of Katy's physical, social and economic assets and liabilities. b. Projection of its goals for future development. c. Formulation of policies to achieve those goals. d. A program and outline of the facilities and services the City should plan to provide.
A physical development plan sufficiently comprehensive that the City will know what it should and desires to build and where.
Tentative scheduling for new development so that construction of new and improved public facilities keeps pace with needs instead of becoming uncomfortably far behind or uneconomically too far ahead of needs.
5. OBJECTIVES
The Comprehensive Plan for Katy pertains to the elements of the urban structure and its expansion with four general objectives: a. To protect the quality of life for all of Katy's citizens. b. To help the city solve existing problems. c. To guide future growth toward a specific, desirable and economical pattern. d. To use land area and the valuable resources to the betterment of everyone.
The first consideration in the development of Katy is for its people. Some of the important factors of this consideration which fall under the four general objectives stated above are:
Page -2- To protect the developed area from damaging flooding, erosion, or hazardous living conditions.
To protect residential areas from incompatible land uses.
To provide and encourage greater safety in vehicular movements.
To provide opportunities to use and enjoy park and recreational areas.
To improve substandard housing areas.
To provide adequate water supply and waste disposal facilities.
To preserve social traditions and historical heritage.
To designate land uses that more closely relate physical characteristics to urban functions.
To establish neighborhood units.
To designate design considerations and minimum public improvements to be furnished at the time of new development.
To establish and consolidate a physical environment that can be adequately serviced and that will promote the health, safety, and welfare of all citizens of the community.
6. PLANNING AREA
The planning area includes Katy's city limits and extraterritorial jurisdiction as agreed with the City of Houston, a total area of eleven square miles. A map of the area is presented on the following page, titled "City of Katy, Texas".
7. ACKNOWLEDGMENT
Information and assistance in updating the Katy Comprehensive Plan was received from a number of sources. In particular, the help and encouragement of the Mayor and City Council, the City Secretary and staff, and the City Planning and Zoning Commission is gratefully acknowledged.

BASE STUDIES
1. GENERAL INFORMATION
The economic base study will provide the locally elected officials with the economic information necessary to enable them to adequately plan for future services required by the City. This chapter of the Plan is basic to all elements of long-range urban planning, and will include the City's physical characteristics, an inventory and analysis of the economic composition and potential of the Katy planning area, an appraisal of population growth, the characteristics of the people, and forecasts of the population increase.
is a small with a Katy city strategic geographical location. Its corporate area is spread over the junction point of the boundaries of three counties - Harris, Waller and Fort Bend Counties. Although certain factors determine its may geographical direction of growth, the City possesses an inviting economic potential. Katy is located in the western portion of the Houston Standard Metropolitan Statistical Area and is within half an hour of downtown Houston. This location provides many economic, social, and cultural opportunities for the citizens of Katy.
Due to its proximity to Houston and the impact that the economy of Houston and Harris County has the economic conditions of the the upon City, economy of Katy is largely dependent upon the Houston metropolitan area. Most economic trends registered by Houston will also be realized in Katy. Economic data available for Houston and Harris County will be of interest to citizens ofKaty. It should be noted that with a of in Katy, population 2,113 1960, was not enumerated in many sources of information. secondary In the 1980 census, Katy was enumerated in "Places of 2,500 to 10,000". With the current population estimated to be in excess of 12,000, the City of Katy will be covered by more sources of information.
The projections given in the study should be subject to constant revision, and updated frequently. Due to the nature of the nation's dynamic economy, and in particular Katy's location near one of the United States' major financial and growth centers, changes can and will occur quite rapidly.
The natural characteristics of the area, formally known as " environmental controls",are those characteristics native to the particular area under consideration. The development of these characteristics will have considerable influence on the development of the region. Man has always faced the of problem adapting to his natural environment; therefore, a thorough familiarization of all the natural resources area of the is important to the planning process.
2. GEOLOGY
Katy is located in the Texas Gulf Coastal Plains, an extension of the Coastal Plain which extends from the Atlantic to the Rio Grande and into Mexico. The western limit of the Texas Gulf Coastal
Page -5- Plain is the Balcones Fault and Escarpment, which extends eastward from a point near Del Rio, Texas. This fault is the generally accepted boundary between lowland and upland Texas. Katy, of course, is located in the lowland section. Below this fault line, the surface is characteristically composed of soil brought down from above and deposited as new earth.
The Coastal Prairies are a region of the Gulf Coastal Plain. Katy lies in the southwestern region of the Coastal Prairies. The eastern half of the Coastal Prairies is covered with a heavy growth of grass, while the western half is a more arid area and is covered with short grass and, in some places, with small timber and brush. The soil is heavily alluvial, consisting of the Lissie, Willis, Golian sands, and Largarto clay. The grass supports the greatest density of cattle population in Texas, making ranching a principal occupation. Rice is the major cash crop, usually grown under irrigation from wells or rivers. Cotton and truck crops are also grown in this area.
Beneath the area surrounding Katy lies the major underground aquifer in Texas, the Gulf Coast Aquifer. Deep wells, used to supply water for rice crops, produce in excess of 2,500 gallons of water per minute.
3. CLIMATOLOGY
Katy is located in the Upper Coast Area, as designated by the U.S. Weather Bureau, which has a generally temperate climate. However, the weather is subject to extreme climatic conditions. The City is situated within 75 miles of the Gulf of Mexico and therefore experiences the effects of turbulence and rain squalls that develop within the Gulf region. Of particular interest are hurricanes and other types of severe weather that move inland from the Gulf. Although Katy is far enough from the coast that it would not experience the full force of a tropical storm, the City would receive severe rain, wind, and flood damage before a storm moving inland dissipated.
Although the weather is usually temperate, sudden changes in temperature are not unusual. The occasional periods of severe cold are short; consequently, fair,mild weather often occurs in January. Likewise, extremely high temperatures of summer rarely prevail for an extended period of time. The highest temperatures in summer are usually accompanied by fair skies and a mild wind, typical of regions along the Coastal Plains. The prevailing winds average about 10 miles per hour and are from a southerly direction. There are a few nights each summer when the minimum temperature is above 80 degrees. Hot periods in the summer are often broken for three to five-day periods by thunderstorm activity.
During the winter, sudden changes in temperature occur with the passage of polar air masses from the north. On the whole, winters are relatively mild, but "northers" occur five or six times a year bringing below-freezing temperatures for two or three-day periods. Days with maximum temperatures of less than 32 degrees are infrequent. Hail and snow are unimportant sources of moisture, and measurable snowfall is rare.

The current enrollment in Katy schools (April, 2001) is 34,892 (12,944 in 1982). The District experienced an increase of 269 percent for the 19-year period, 1982 - 2001. The comparable increase for the preceding decade was 548 percent.
Teacher salary levels are shown in the following table:
Degree Achieved Bachelor Master Doctorate
Salary $ 33,00000. 35,00 000. $36,00 000. $
Approximately fifty-five to sixty percent of Katy High School graduates continue their education in college.
Katy has a local library that is a branch of the Harris County Library System. In March, 1975, the old fire on station Second Street was dedicated to the Library. This provided 2,150 square feet of space to house the 9,000 volumes in the Branch. The library has two full-time employees. Katy supplies a part-time aid during the summer to assist with the increased activity. The library sponsors

Youth organizations are active and strongly supported by the Katy citizens. These include Boy Scouts of America, Girl Scouts of America, and The Camp Fire Girls. The school system sponsors several youth organizations, two of which are the Future Homemakers of America (FHA)and Future Farmers of America (FFA).
There is an 18-hole golf course located at the Katy Country Club available to members, their guests, and local residents, who are charged a greens fee.
Galveston and other sites along the coast offer excellent vacation and recreation opportunities and are within a short drive of Katy. Boating, surf'mg, and skiing are popular all along the Texas Gulf Coast. Stephen F. Austin State Park, located about 18 miles west of Katy, provides boating, fishing, and picnic areas along the Brazos River. The park also has a nine-hole golf course. Bear Creek Park located 14 miles east of Katy, provides camping, picnicking, golf, organized sports, playground, hiking, and open space.
is a Hunting favorite of many sportsmen in the area. Duck, geese, quail, and dove are plentiful during the hunting season. Deer hunting is also a popular sport in the area.
Katy residents are also fortunate in being near enough to enjoy the diversified cultural activities constantly being conducted in metropolitan Houston.
9. FIRE DEPARTMENT
The Katy Volunteer Fire Department does not employ full-time personnel, but the City of Katy does hire full-time EMS employees. At present, there is a volunteer fire chief and 50 volunteer firemen. The one fire Department operates station and seven vehicles. The vehicles are: one 1500 gpm American LaFrance Pumper, one 1000 gpm Ward LaFrance Pumper, on 400-gallon self-contained Ford Sims one pumper, 300-gallon self-contained Chevrolet Howe pumper, one 600-gallon Army and one rescue surplus pumper and emergency vehicle equipped with Hurst rescue tool, oxygen, two resuscitators, and other emergency equipment. All units are radio-equipped as well as officer's vehicles. All volunteers are equipped with pocket pagers. Katy has a comparatively low Fire Insurance Rate at present.
Katy is participating with Harris County Civil Defense Network and is integrated into the Civil Defense Plan of Houston and Harris County.
10. POLICE DEPARTMENT
Since 1969, the Katy Police Department has grown from a force of two full-time officers and a dispatcher to forty-one certified officers and six civilian employees. In 1970, the Department owned two vehicles. Today, there are seventeen marked cars, nine unmarked cars, four motorcycles, and
Page -10- two animal control vehicles for a total fleet of thirty-three vehicles. All units have high band radio equipment and the Department operates twenty-one radar units. Three officers are assigned to crime investigation duties. Today, three of the officers are trained in crime prevention techniques and the City also utilizes two juvenile officers.
Katy has been fortunate in having a very low rate of major crime. Burglaries have consisted largely of break-ins by juveniles or non-professional criminals and have involved small amounts of property. However, the addition of Katy Mills Mall has created an increase in petty theft and employee crime in the City of Katy. The City opened a police substation in the Katy Mills Mall in October, 1999 to serve the Mall area. The Department utilizes 27 patrol units and provides 24-hour coverage seven days a week.
11. COMMUNICATIONS
The local of THE newspaper Katy, TIMES, is published biweekly and has a circulation of 8,500 up from 5,900 in 1980. The paper serves the Katy and Royal School Districts and reports the activities of many of the housing subdivisions within its service area.
Mail and carrier delivery is made daily of THE HOUSTON CHRONICLE. Six television stations are received by area residents, which are:
Channel Call Letters Location Network
2 KPRC-TV Houston NBC
8 KUHT-TV Univ. of Houston PBS
11 KHOU-TV Houston CBS
13 KTRK-TV Houston ABC
26 KRIV-TV Houston Independent
39 KHTV-TV Houston Independent
12. UTILITIES
Reliant Energy supplies electric power and natural gas for home, industry, and agriculture. Telephone service is furnished by TXU Communications, formerly Fort Bend Telephone Company. The City of Katy provides water, sewer, and garbage service for its residents.
Page-11~ 13. TRANSPORTATION
Katy is served by one railroad: The Missouri, Kansas, and Texas Railroad. Bus service is provided by Continental Bus Company and Kerrville Bus System. Two local commercial establishments and several farms have hard sod runways available for light aircraft. Katy has been studying the feasibility of creating a municipal airport, but in 1979, public opposition to the proposal caused the administration to terminate the study. There has been some discussion of the possibility that a private group will undertake establishing an airport in the vicinity, but no definite plans have been made public at this time. Nearby Houston offers a complete transportation network to adequately serve all of Katy's needs. Katy is served by U.S. Highway 90, a main highway route for east-west traffic and I.H. 10. There are 5.5 miles of highways passing through Katy. The Houston Mass Transit Authority, established in 1968 to deal with Harris County transportation problems, has established several park-rideand-facilities in the Katy area. Bus service is then provided from these facilities into the downtown Houston area.
14. ECONOMIC BASE
The economy of Katy has historically been based on agricultural production and natural resources. Increasingly, the area is becoming a base for commuters and a location for light industry. With the addition of major industries such as TXI, Hope Lumber Company along with the Katy Mills Mall and its outparcel development, the economic base of Katy has diversified.
15. NATURAL RESOURCES
The North Delhi Oil Field, portions of the Clodine Field, and the extensive Katy Oil and Gas Field are located in and around the Katy area. The Katy field covers 32,000 acres and is utilized by major petroleum corporations, the six largest owners being Exxon, Pan American Petroleum Company, Sun Oil Company, Tidewater Oil Company, Atlantic Refining Company and Mobil Oil Corporation.
In 1967, Humble and Pan American announced that negotiations had been completed for the sale of large quantities of gas from the field. United Gas Pipe Line Company, Lone Star Gas Company, and Pan American Gas Company purchased the gas under twenty-year contracts.
Although it was realized early in the 1930's that a major gas condensate reserve had been discovered, the lack of a market for the gas discouraged additional drilling. In the early 1940's, a market for the gas had developed and drilling was again undertaken. In order to enjoy a continuous stream of revenue from the gas resource, a gas cycling plant was built in 1943. Gas cycling is the process of producing natural gas from a well, extracting from the gas liquified hydrocarbons, then compressing the dry residue gas and returning it through another well to the reservoir from which it was produced. The gas cycling project was undertaken by thirty-two companies with Humble Oil and Refining Company chosen as its operator.
Page -12- The plant has a daily input of 550 million cubic feet of natural gas. The primary products are gasoline and a mixture of ethane-propane. Employment at the plant includes professional, skilled, and unskilled labor.
North of Katy is the United Salt Corporation's Hockley division salt mine. This is believed to be one of the deepest and largest single deposits of salt in the North American continent. The depth of the deposit is over 22,000 feet and covers an area of 5,500 acres circumscribed by the outside perimeter of the dome. The process of pillar-tunnel mining is used.
16. AGRICULTURE
Historically, rice has been a major agricultural crop in the Katy area. There were 60,000 acres of land devoted to the rice industry in 1969 in the Katy and surrounding areas. The number of acres of land in rice production has dropped sharply in the past twenty years and all indications are that this trend will continue. The high cost of production, low rice prices, high land costs and shortages of water for irrigation are some of the factors that have led to this decline.
While rice farming has declined, the number of cattle in the area has increased. Most cattle are crossbred for beef production, but there are registered herds in the area that produce breeding stock.

HOUSING
1. INVENTORY
Exhibit C shows the location and classification of all the buildings in Katy. The following definitions explain the meanings of classifications. The following tables show the stock of buildings and the classification given to each structure: a. Definitions
Structure--a Single-Family permanent structure that is used by individuals and/or families for living purposes. It is detached from other housing units.
Unit--a Multi-Family permanent structure which is used by individuals and/or families for It is attached to other living purposes. housing units in single level or multiple level structures.
Mobile Home ( Manufactured Home, HUD Code)--means a structure consmacted on or after June 15, 1976, according to the rules of the United States Department of and Urban Housing Development, transportable in one or more sections, which, in the is feet or more traveling mode, eight body in width or 40 body feet or more in when erected on is or length, or, site, 320 more square feet, and which is built on a chassis and to be used as a permanent designed dwelling with or without a permanent foundation when connected to the required utilities, and includes the plumbing, heating, air conditioning and electrical systems.

Deteriorated--a structure that has deteriorated from ten percent (10%)to fifty of its value. An percent (50%) highest observation of such a structure may reveal physical problems ranging from rotted siding and roof deterioration to foundation problems and limited structural damage.
Dilapidated--a structure that has deteriorated more than fifty percent of its highest value. An observation of such a structure may reveal a number of physical problems consisting of severe foundation problems, extensive structural damage, roof deterioration, rotted siding, electrical problems, and plumbing problems.
Page -14-
The problems facing the City are:
A concentration of dilapidated residential structures in the area mentioned above. Dilapidated units cause many problems for the City because they are often abandoned, thus creating health and safety concerns for surrounding residents. Once abandoned, the units can be a source of rodent and insect activity, and also a source of criminal mischief.
A significant number of deteriorated residential structures ( 153) and mobile homes ( that could 81) become dilapidated without proper maintenance.
A significant number of deteriorated multi family units (90).
A significant number of deteriorated commercial structures (44).
code Through proper enforcement and awareness, many of the housing related issues can be resolved before they become a threat to the health and safety of the community.
The City has the following building codes and related ordinances:
Uniform Building Code Junk Ordinance Unsafe Structure Ordinance Weed and Debris Ordinance b. Previous Implementation Actions
In 1995, the City was awarded a $50,00000.grant for housing rehabilitation through the Harris County Community Development Block Grant (CDBG) Program.
Texas Department of Housing and Community Affairs (TDHCA)
The City is part of the Harris County Community Development Block Grant CDBG) Entitlement Program. The City receives funds from time to time for the purpose of repairing and/or clearing dilapidated structures in designated low to moderate income areas within the corporate limits. Funding has also in other used been, years, to make infrastructure improvements in that area. Harris County is required to submit an aImual action plan for the distribution of CDBG funds. At this time each year, funding recommendations are considered. Page - 18- 3. HOUSING PLAN
The of has City Katy the following stated goal for housing: Assist residents in the procurement of affordable in a safe, housing fair and equitable manner, and encourage reputable developers to provide that housing.
The annual and following objective implementation actions based on the previous analysis are intended to benefit the entire City:
2000-2001
1' a Objective Prepare yearly housing rehabilitation program by:
mo Making plans to secure yearly funding from the Harris County CDBG Program for housing rehabilitation.
Bo Budgeting funds for minor repair work (Roofs, siding, etc.)for qualified low to moderate income individuals and families. Collect on a basis and applications yearly rank the applications based on a scoring system.
2: Objective Establish four (4)priority areas (quadrants) and begin clean-up activities in Priority Area #1.
mo Hire outside assistance, if necessary, to find the owners of lots with vacant dilapidated structures through the use of title searches. Enforce the substandard structures ordinance when the proper owner/owners are found.
Bo funds to Budget clean up lots with vacant dilapidated structures, debris and/or uncontrolled vegetation. These funds should be used after all possible administrative and legal efforts have been made to the owner to clean require the property. The City should place a lien on the property after the cleaning work has been finished.
Aggressively acquire tax delinquent properties with vacant dilapidated structures.
Do Contact the Texas Historical Commission (THC)to determine the eligibility of any purchased properties for the State or National registry.
Demolish and clear dilapidated, non-historic structures in order to remove potential health and safety hazards.

3. FUTURE POPULATION
The future population projections of Katy are shown on the graph in Exhibit D. The city of Katy has limited population growth potential because the city of Houston's Extra- Territorial Jurisdiction ( ETJ) surrounds the ETJ of Katy. Therefore, the city of Katy is landlocked.
had in the 1980's and Katy steady growth 1990's of approximately forty-four percent and 44%)forty- eight percent (48%)respectively. This growth was probably due to the small town and atmosphere location that is desirable for people who commute to nearby Houston. There are an abundance of jobs and people are willing to make thirty to forty- five ( 30-45)mile commutes. The City of Houston is ranked fourth (4th) in the nation in terms of population (see Table 4),and the Houston Metropolitan Statistical Area (MSA) is ranked twenty-second (22nd) in terms of percentage change from 1997-1998 (see Table 5).
Growth is mainly anticipated from commuters working in expanded regional industry and new industry. Growth can also be expected to occur in the form of retirees. Many people have the means to retire at an earlier age, and cities like Katy and Brookshire offer the amenities seek. These people communities offer small town atmosphere with access to large city conveniences. For this reason, Katy has good potential for economic development due to its location on Interstate 10 and its proximity to the state's largest city.

In the 1974, City reached an agreement with the City of Houston fixing the limits of ETJ. Katy's As mentioned earlier, Katy's ETJ is surrounded by the City of Houston's ETJ. As a result of that agreement, the city of Katy's boundaries could only be expanded to 6,930 acres. Therefore, residential can occur expansion in one of two ways; either by land use to converting agricultural residential, or by developing the remaining 1,196 acres within the ETJ. Development potential will be defined as seventy-five percent (75%)of the existing agricultural land use, and the remainder of the ETJ. The aforementioned will be considered the development potential maximum build-out growth for the year 2020. The development potential is then added to the current population figure.
the aforementioned Using assumptions, the population for the year 2020 is calculated below:
Maximum Development
3.330 acres for development = 24,667 persons 0.135 app
24,667 12,089 36,756 (2020 Population)
The population projection derived by this method is shown as the maximum population growth line. Realistically, the population for Katy will probably fall somewhere between these two scales. It is unclear at what rate the agricultural land use will shift to but the shift does residential, appear inevitable as the City continues to become more urbanized. This population projection method does not recognize an anomaly of a major subdivision development, or apartment complex with high density housing which would skew the curve population upward. These anomalies may be expected but the intensity is not known and cannot be used in a solid population projection.

DEVELOPMENT STANDARDS
The previous "Base Studies" are an attempt to summarize Katy's previous community development and to project or estimate future trends in the City's population, business, and residential characteristics. Since zoning was enacted in 1983, the development in Katy has been fairly orderly.
In the past decade, several major factors that will influence development in the Katy area in the future have come to the forefront. Included in these are the forced conversion of the Houston area to surface water, the high cost of treating large volumes of sewage effluent, the drainage problems, and traffic congestion made worse by unbridled development. The problems had little effect in the Katy area until the past ten years.
All of the potable water used in the City of Katy comes from ground water production. The large volume of ground water used in the Houston area has led to subsidence which has added to the flooding problems in the Houston area. To combat this problem, a subsidence district was set by Harris and Galveston Counties (Harris Galveston Coastal Subsidence District [HGCSD]).Fort Bend County followed this lead more than ten years later creating Fort Bend County Subsidence District. The City of Katy is in Harris Galveston Coastal Subsidence District Regulatory Area 3. Under their rules, the City of Katy has until 2003 to come up with a ground water reduction plan and is mandated to reduce its groundwater usage in the Harris County portion of the City by thirty percent by 2010. The Subsidence District is also proposing a surcharge of 3.$ 00 per one thousand gallons of water withdrawn from the Harris County wells if all of their time tables are not met. Although Fort Bend County has not yet implemented any rules on converting to surface water, this will likely happen in the short term.
The City of Katy utilizes one sewage treatment plant at this time which is rated at 1.8 million gallons per day. To keep up with the current growth, the City is planning to expand the plant to 3.2 million gallons per day. The cost of this expansion is estimated to be in the $3,000600,range. Over the past decade, the rules propagated by the Environmental Protection Agency and the Texas Natural Resource Conservation Commission have increased the cost of both building and operating sewage treatment plants.
The City of Katy is located in the Gulf Coast Region of Texas which is very flat. This always led to drainage problems but the large amount of growth in the past ten years has heightened the problems and the citizens' awareness of the problem. Katy is contained in three separate drainage districts: Harris County Drainage District, Fort Bend County Drainage District and Brookshire-Katy Drainage District. The City has adopted the rules of Harris County Drainage District for developing property in the City's Extraterritorial Jurisdiction (ETJ).These rules require detention be utilized to offset any additional runoff created by development. The City has carefully studied the flooding problems beginning with a study completed in March, 1996 funded by the Texas Water Development Board. A second study authored by Dodson & Associates was completed in
Page -27- 2001 and furnished the City of Katy with an accurate computer model of the Cane Island Branch The Dodson Drainage System. study also evaluated the fin'st location for a City of Katy regional detention The obvious pond. problem with development is the smaller the lot size, the higher of the percentage impervious area, greater the runoff created and the higher the peak flow generated. An economical and environmentally friendly solution to drainage problems versus future is to increase the area development green allowing more of the rainfall to soak into the ground. This can be accomplished by increasing the lot size and increasing the building lines.
In the comprehensive plans done previously, traffic flow was not a large consideration. Since 1995, the amount of traffic in the immediate Katy area has greatly increased. Katy is now suffering from the same traffic that Houston has problems already experienced. The amount of traffic on the major in thoroughfares Katy, especially Highway Blvd. Hwy.( 90),Avenue D,Katyland Drive, and Pin Oak Road has increased extremely fast. The major thoroughfares outside the city limits, Interstate 10, 6, Farm-Marketto-Road Highway 1093, are even more congested. The City has planned for additional streets to the help congestion and the Texas Department of Transportation has to Interstate but the total planned expand 10, amount of traffic needs to be limited for either to have any success. The traffic has created another congestion problem within the last three years; the problem of air The TNRCC is pollution. mandating that the Houston area reduce the air pollution through several Included in these are painful steps. lowering the speed limit in the Houston area to 55 of cars mph, requiring tailpipe testing in the whole Houston area, limiting the time when construction be used and equipment may requiring concessions from industry on air discharges. The amount of air increases pollution greatly as cars are driven during stop and go traffic.
The of should limit its ultimate City Katy population to insure that the City can furnish clean, affordable water for its citizens, treat the sewage effluent from the homes and businesses in its jurisdiction, furnish streets with along roadways that are safe with little congestion, have lot sizes of sufficient size to allow areas for green rainwater to soak in and not create additional flooding, along with keeping the traffic down to help reduce air pollution.

NEIGHBORHOOD CONCEPT
The idea of neighborhood development was introduced in Katy's 1969 Comprehensive Plan. It is an idea which needs to be considered by potential developers before acquiring land for some predetermined purpose. Therefore, the neighborhood concept will be reprinted below from the City's 1969 Comprehensive Plan. The other factor that developers should consider before buying property for a set use is the zoning designation of the tract.
One of the most important principles in land use planning is that which concerns itself with referred to as the " neighborhood development - neighborhood concept".The neighborhood is a unit whose land use and functions tend to be more inwardly orientated rather than outward as many urban uses are. The Central Business District, for example, is one that is and should be orientated outward, for it strives to bring people from all quarters of the City into the area and is, therefore, usually designed and equipped to accommodate the concentrations of people, traffic and services that it needs to exist. The neighborhood, however, strives only to serve as a quiet, safe, and healthy living environment for the people who reside within its confines.
The " in is to or neighborhood concept", planning, plan for create one, two, three, or as many of the "neighborhoods" as will be needed to accommodate the City's future population. The size of a neighborhood will vary somewhat depending upon topography, density and urban characteristics, but in general should contain a range between 3,500 and 5,000 people. One tool of the is to concept identify that unit by giving it boundaries and creating an atmosphere of inward orientations as far as the residential land use is concerned. This is partly achieved by creating a street pattern that will carry major traffic around the unit and discourage heavy, high-speed traffic from cutting through the unit to a destination other than the interior of the unit itself. Land use zones and patterns should be established that are appropriate to their locations and orientation. The interior of the for should be unit, instance, primarily residential with the heavy traffic attractions, such as commercial on uses, located the exterior of the unit. The neighborhood elementary school and park should be located near the center of the unit in order to allow all sections of the neighborhood to be within distance of both easy walking facilities. The neighborhood school and park will also serve to give the neighborhood a central focal point and center of interest.
Within the there a neighborhood unit, is need for uses which support the residential area. These are the neighborhood commercial uses, churches, lodges, clubs and any other use which might be considered an appurtenance to the residential development. These appurtenances are best located near or on the exterior of the neighborhood and, in the case of commercial use, should be located at the intersection of major streets. In the case of uses of a public nature, these are best located at the intersection of or secondary secondary and major streets, so that they may be easily reached by the people who use them.
The following map is an illustration of the " Typical Neighborhood". The typical neighborhood as shown is what might be considered an ideal situation. This is the type of

b. Analysis
1) Occupied Dwelling Units
Cun'ently, the City of Katy has 4,098 occupied dwelling units which constitutes a 98.3%occupancy rate. Many of the vacant units are deteriorated and dilapidated residential structures and mobile homes. The vacant dilapidated units should be demolished to alleviate fire and health hazards and/or to make room for additional housing units. The occupied dilapidated units should be repaired (either by the individual homeowner, or through a City sponsored housing rehabilitation program) in accordance w/th local building codes, in order to alleviate any potential health hazards. The deteriorated units should be monitored closely in order to prevent potential dilapidation. A minor repairs rehabilitation program could be initiated by the City to help individual homeowners with items such as roof replacement and deteriorated siding.
2) Existing and anticipated population
The population study which is a part of this plan utilizes a linear progression of past population growth rates and the total build out of furore residential acres for population projections. The existing population is 12,089 according to the currently occupied housing units multiplied by the 1990 Census number of persons per household. The maximum anticipated population for 2000 is 12,089 and for 2020 is 36,756. The population in Katy has been steadily increasing for the last twenty (20) years. This increase will probably continue.
3) Soils characteristics
According to the Soil Survey of Harris, Fort Bend, and Waller Counties by the Natural Resources Conservation Service, the predominant soils in Katy are Lissie, Willis, Goliad sands, and Largarto Clay. Katy is located in the Texas Gulf Coastal Plains, an extension of the Coastal Plain.
4) Adequacy of public utilities
For existing developed land, utilities are available. Utilities do not exist in some vacant and agricultural land areas that could be used for development. In undeveloped areas, lines will have to be constructed to serve those future users. The same holds true for other utilities--gas, electric, telephone. Capacity is available but lines will have to be constructed to some of these vacant areas.
5) Adequacy of public facilities
The following public facilities are located in the City of Katy:

Funding Source & Background
The Low Income Housing Tax Credit (LIHTC)Program was created by the Tax Reform Act of 1986, and was first utilized by the real estate development community during calendar 1987. Section 42 year of the Internal Revenue Code of 1986, as amended (the is the law Code), federal that governs the LIHTC program. It authorizes tax credits in the amount of 1.$ 25 per capita for each state. The Department has approximately $22.3 million in tax credits in the 1998 state housing credit ceiling. The tax credit program is the pr/mary means of directing private capital towards the creation of affordable rental housing. The tax credits provide developers of low income rental with a housing benefit that is used to offset a portion of their federal tax liability in exchange for the production of affordable rental housing. Since 1987, the LIHTC has more than $ program provided 145.8 million in tax credits that are projected to produce more than 67,300 apartment units throughout the state of Texas. The amount of tax credits for which a project owner is eligible is determined by the amount of qualified development costs to be incurred and the percentage of low income units set aside within a development that meet the applicable federal requirements for both tenant income and maximum rental rates.
Program Description Each tax credit qualified development must include a minimum percentage of units to be set aside for low income eligible tenants. The rent charged on these set-aside units must be restricted.
Pursuant to a low Code, qualified income housing project means any project for residential rental occupancy if the project meets either of the following requirements: or more of the Twenty percent (20%) residential units in such project are both rent restricted and individuals whose occupied by income is fifty percent (50%)or less AMFI; or
or more of the Forty percent (40%) residential units in such project are both rent restricted and individuals occupied by whose income is sixty percent (60%)or less of AMFI. Tax credits may only be claimed on the units that have been set-aside for participation under this It is program. possible for project owners to set aside one-hundred percent of for consideration under 100%)any project the tax credit program and in doing so claim the maximum amount of tax credits eligible for the development.
Summary of Need The 1995 state Low Income Housing Plan reports that thirty-five percent (35%)of all low income households in the state pay more than fifty percent (50%)of their gross income on rents. Additionally, three Texas cities - San Antonio, Houston and Dallas - were ranked among the nine large metropolitan areas nationally with the highest incidence of overcrowding among poor renters. The tax credit program helps meet the needs of such households by increasing the supply of affordable rental housing.
Page -41- Program Administration Pursuant to Section 42 of the Code, the Department must develop a plan for the selection of eligible projects based on broad guidelines designed to provide housing for the Iow income tenants. Applications are received by the Department and evaluated under such a plan at least once a year. The Department recommends an allocation of credits based on many factors, such as geographic location, type of housing, the concentration of low income projects within specific markets or sub-markets, site conditions, the experience of the development team and/or the project's impact on the goals and objectives of the program. These recommendations are presented to the Department's governing board for approval. At least ten percent (10%)of the state allocation is set-aside for qualified nonprofit organizations. The application cycle for 1997 is expected to commence in June. The projected funding for 1997 is $24 million with the total number of households expected to be served is 4,800. All areas o£the state are eligible for funding.
LIHTC Program Funding Categories Assistance through the LIHTC program is available through the funding categories listed below:
Funding Percent of Allocation Projected for 1998 Categories
1. General 75%in the amount of 18,000$ 000, 2.Nonprofit 10%in the amount of 2,000$ 400, 3.Rural Project/Prison 15%in the amount of 3,000$ 600, Commut~ty ** Twenty-five percent (25%)apportionment for projects financed through Rural Development (TxRD).
Tax Credit Ad Hoc Committee The Tax Credit Ad Hoc Committee of the Department's governing board is comprised of three members from the board charged with the direct oversight of the LIHTC program.
Additional Initiatives Efforts are made in the allocation of funds and the planning process to ensure the involvement of housing advocates, community-based institutions, developers and local municipalities. The Department encourages local cities to support and contribute funds toward the development of tax credit projects. The program targets areas that are designated for redevelopment activity through our point system of scoring. Also, the Department encourages the participation of community development corporations and other neighborhood-based groups. Page 42-
Funding Source & Background
The HOME Program, established by Congress in 1990, provides multi-year housing for " strategies participating jurisdictions"PJs) ( to strengthen public-private partnerships and more affordable via block provide housing grants. PJs are units of government so the designated by U.S.Department of Housing and Urban Development (HUD).In general, of the cities and counties in many larger Texas are PJs in their own right. TDHCA receives a statewide block grant of HOME funds for areas of the state which have not received a PJ status separate from HUD. Allocations are made on an annual basis by formula based on several criteria: number of substandard rental units, per capita income levels, number of families at or below the poverty level and cost of housing within a region. A HUD allocation is based on a five-year plan for distribution. TDHCA must review and award applications contracts to applicants within two years from the date of HUD allocation. the end of By the five-year term, all money from an allocation must be expended for HOME activities. The state is eligible required to match twenty-five percent of the HOME 25%) allocation from HUD. This match can be in the form of cash dollars, in-kind" contributions and other means.
Program Description
Under HUD HOME funds are guidelines, reserved for people at or below 80 percent of 80%)Average Median Family Income ("AMFI")for an area. TDHCA awards contracts through a competitive application process for specific amounts to various municipalities, non profit agencies, for profit and public housing agencies around the state to administer program activities for HOME eligible recipients. HOME allow for a regulations variety of housing activities, all aimed at providing safe, decent affordable housing to low income families. TDHCA has allocated funds to grantees in four basic housing activities: Homebuyer Assistance Program; Rental Housing Development Pro,am; Owner-Occupied Housing Assistance Program; Tenant-Based Rental Assistance Program; Repair or Replacement of Single Family Dwellings The HOME Program's Owner Occupied Program provides funds for the rehabilitation of homes. This single family program includes, roof repair or replacement, electrical system and plumbing repairs. After the construction is completed, the homes must meet Texas Minimum Construction Standards. eln order to qualify for this program, an individual must own and reside in their home. Rent houses are not eligible. a home not be Sometimes, may repairable, In those instances, a home may be demolished and replaced by a "stick-built"or a manufactured home. Homebuyer Assistance Under the Assistance Homebuyer Program, individuals may receive up to $10,000 for down payment, closing costs and gap financing. This loan is not repayable until after the
Page -44- mortgage is paid offor upon refinance or sale of the home. The homebuyer must use the house as his/her principal place of residence. The title to the must transfer to property the homeowner, therefore, contracts for deed are not eligible for this program. Rental Property The Rental Project Development Program provides funds to build, acquire and/or rehabilitate rental property. Buildings may be on the same site or scattered sites. HOME has funded the construction of duplexes, fourplexcs, apartments and single-family homes. In addition, developments bc mixed mixed may income, use, single room occupancy, or transitional housing. Rental Assistance The Tenant Based Rental Assistance Program subsidizes rents and pays security Thc deposits. assistance is portable, which means the tenant is not restricted to living in a particular apartment The assistance is available a complex. for maximum of two years. As a condition to receiving the subsidized rent payments, tenants must participate in a self-sufficiency program. Self-Sufficiency programs will vary, depending on the population served. Self-Sufficiency Programs may include drug dependency classes, job training, college degree programs, parenting training and GED classes. the HOME Additionally, Program operates the HOME Demonstration Fund in which the HOME with other Program participates TDHCA divisions such as the Low Income Housing Tax Credit Weatherization Program, Assistance Program and the Single Family Loan The Demonstration Program. Fund also contains a small amount of funding for emergency projects, innovative projects and direct awards. Two reservations have been mandated for the HOME Program. Under HUD regulations, TDHCA must set aside fifteen percent (15%)of our total allocation for Community Housing Development The other a Organizations (CHDOs). is five percent (5%)reserve for the " needs" special category mandated by the Texas Legislature. In addition, the Department has elected to reserve ten percent (10%)for special needs. This special needs category includes the low income homeless, elderly, frail elderly, persons with disabilities and persons with AIDS and AIDS-related diseases. Summary of Need Thc state of Texas is a of experiencing shortage affordable housing. Eighty-one percent of all state of Texas 81%) Consolidated Plan survey respondents indicated that their need for affordable community's housing is outpacing the supply. According to the needs assessment of thc state of Texas Consolidated Plan, an estimated 1,683910,households in Texas will be in need of housing assistance in the year 2000. Program Administration Since the Home in Program's inception 1992, TDHCA has awarded in excess of 240$ million. For the four TDHCA's HUD past years, allocation has continued to grow; however, it is that future anticipated funding may begin to decrease as HUD attempts to reconcile the issue of expiring Section 8 vouchers and Congress attempts to balance the budget. TDHCA's 2000 HOME allocation is estimated to bc $34,000.000, TDHCA receives ten percent (10%)of thc HUD allocated funds for administrative costs of the at both program the state and local levels. Historically, the Department has reserved six percent (6%)for state administrative expensive and four percent (4%)or local administrative expenses. Page -45-
THOROUGHFARE PLAN
1. INTRODUCTION
During the 1990's, the most visible perhaps development in the transportation field has been the failure of the conventional " people moving"systems. The near-downtown segments of the freeways were immediately overloaded when in the they opened 1960's.The congestion has spread from this center in every direction since that time. The traffic problems now start just east of Katy in the early morning hours and when afternoon again traffic increases. Until the early 1990's,the traffic on problems Houston's were limited to a freeway systems short duration of time in the early morning and in the afternoons. Now on Houston congestion freeways may be encountered at anytime of the day.
The Texas Department of has to Transportation plans increase the number of lanes through the City of Katy in the next five These years. plans will definitely benefit the citizens of Katy but additional North-South access points are needed to move citizens to the freeways. The City of Katy has agreed with TX DOT to construct a new interchange on Interstate 10 between Farm-Marketto-Road 1463 and Pederson Road. will then construct a new Katy thoroughfare connecting from Interstate 10 to link up with Pitts Road. This will a new provide connection point with the west side of Katy from Farm-Marketto-Road 529 to Interstate 10.
Within the a City, planned grid of is to major thoroughfares essential orderly development and public safety. For example, builders must know in advance of their site planning if the City's needs will require additional their right-wayof-along development boundary if a new street is planned through or near their The project. City Planning Commission uses the thoroughfare plan to evaluate and coordinate proposals of subdividers and other developers. The City Council must have a thoroughfare plan in order to provide capital improvements on a farsighted basis. Thus, the third of purpose this chapter is to provide a useful to each such guide public and private group to assist in the conduct of their business.
2. BACKGROUND
Streets that serve different have purposes developed through the growth of population concentrations. Since the advent and intensive use of the automobile as the primary source of transportation in the urban the street structure, system has taken on new functions and has required major alterations in some cities. Out of these new functions, freeways, expressways, and super- streets have in order emerged that traffic may move freely from its origin to its destination.
Another development in vehicular movement is the ever-increasing number of people who move through or about the urban and rural but whose is areas, origin outside the Katy region. This occurs as a result of the of transportation goods and materials from other regions and of the increasing
Page -47- number of tourists and visitors that flock to the roadways in order to enjoy other parts of the Gulf Coast state, and nation. All of these - Region, the employee driving to work, truck deliveries to and from local stores and the flood of industries, commerce to and from other regions, and the scores of Americans new and seeking places, sights, adventures in regions outside of their own - create a mass movement of vehicles that continue to in number and grow exert an ever-increasing influence on the face of America. This mass of traffic, in the urban originating center, has spread to every corner of the country, into the smaller the cities, countryside, and places previously not considered to be traffic attractors or generators.
A prominent, partial solution to this has been the congestion expressway bypass and the expressway loop, which serves the function of not allowing heavy traffic destined to the interior urban area to bypass it. Such a solution eliminates this traffic from the local streets. These expressways help to solve a part of the their to problem; however, help the local interior traffic is sometimes minute. In many instances, the location and of the design expressway bypass in a small community, as in the case of Katy, does little to the local traffic which help must still be borne by the system of streets within the thoroughfare network. The local streets attract the majority of traffic locally and move that traffic to points of destination without ever or using needing the freeway facility. This is where a very important part of the thoroughfare plan evolves.
In earlier of all days urbanization, streets were similar in size and function. The central business district was usually built on a "main or one wider street", than the others, which served as the main entrance to the City. Beyond this "main there was street", little need to consider a system of major streets, since there was little movement within the urban area. The City continued io grow in this fashion until the automobile came along, inheriting a horse-buggyand-pattern of development. The automobile required two clear lanes for in either direction moving and, as volumes built up, four to six moving lanes were needed. In the automobile addition, required space to park on these streets..
From this on, the various streets took on point different functions. The most common street became the "residential street" - a street flanked on either side by homes. These residential streets needed to be only wide to serve the traffic flow enough generated by the homes adjacent to them. Two lanes and one moving parking lane were sufficient and still serve then, the purpose. Today, more versatile secondary streets are thus needed, collecting traffic from the residential streets and feeding it to the major arterial traffic ways. Although secondary streets may pass through neighborhoods, they are usually designed to discourage traffic. through Major streets, being wider and more heavily paved than secondary streets, are continuous for several miles and serve as crosstown streets. Major streets allow vehicles to move at relatively high speeds for long distances, being uninterrupted by many side streets, traffic stop signs, lights, driveways, pedestrian traffic, and other obstacles that occur on the and residential secondary streets. Major streets must be capable of handling the traffic that is generated to them; consequently, they usually provide four to six lanes of moving traffic.
Page 48- 3. PLANNING APPROACH
The approach to this planning phase is much like that taken in other phases of the Comprehensive for it includes the Plan, inventory, the analysis, and the conclusion of plan. For the circulation study, an of inventory existing conditions was made by the Consultant, aided by the local city administrative staff. This inventory included the study of right-wayof-widths, pavement widths and conditions, traffic and street volumes, appurtenances such as bridges, culverts, traffic lights, and street intersections. Also in the important inventory was the determination of some of the more in the street important problems existing system. Following this inventory, an analysis was made for the of two purpose determining things: First, which of the streets in the urban area would be best suited for use as either major or secondary streets; and second, the development of a set of standards which this could be by eventually accomplished. The development standards are presented below. The next was to delineate those streets on a step map and establish a pattern that would best serve the needs of the as it is community projected into the future. The final step was to establish the of phases implementation which could be used by the local administration in guiding the of tliis development system through the use of logical and legal programs and procedures. This will phase review, explore, and project the Katy street system as it should be developed in accordance with the other phases of the Comprehensive Urban Plan.
4. STREET DEVELOPMENT STANDARDS
The definitions and following standards are suggested for streets within new subdivisions and for improvement of existing city streets and thoroughfares.
Residential ( Street - Minor) The residential street is designated to serve only those properties to the adjacent street and is normally constructed 28 to 30 feet wide in 60 feet of right-of- This allows two way. moving lanes of traffic and one parking lane. This street is usually of short length and designed so as to prevent thru-traffic generation.
Secondary - Collector Street - The secondary street is designed to collect the traffic from the residential streets and feed it into the major streets. It should not be developed to as high a standard as the major thoroughfare and should, in most cases, be designed to discourage thru-traffic.
Major Thoroughfares - The major thoroughfare serves as a collector of traffic generated by the secondary streets and as a throughway for traffic traveling long distances through the urban at area, usually higher sustained speeds. This street has a right-wayof-of 60 to 100 feet and is from 44 to usually 64 feet in pavement width, so as to accommodate the same traffic volumes as the divided sections.
and This Expressways Freeways - type of facility is actually a regional facility, built to serve very large areas and move heavy traffic volumes from one area of population concentration
Page-49- to another or move traffic through or around a urban area quickly and without interference from access and exit This consists ways. of the interstate routes, urban loops, and key state highways. The right-wayof-required for such a facility is 300 feet plus, and it is constructed with either complete or partially limited access.
The following table shows the general standards of the recommended major street sections:
Page -50-
5. SAFETY CONSIDERATIONS
There are additional considerations in the construction of major streets. One of the most important is the allowable interference resulting from traffic entering the major street, either from side streets or adjoining properties. It is preferred to keep the major street as free as is possible from this type of interference, for in so doing, it is easier to control traffic, maximum speeds can be safely maintained, and the major street traffic is more apt to proceed safely without the possibilities of accidental mishaps resulting from cross-traffic. A majority of all urban vehicular accidents occur at street intersections, and an effective means of limiting the possibilities of this type of accident limits also the number of intersections on major streets. Several methods may be used to accomplish this. First in platting of subdivisions, it is advisable to limit the number of intersections with the major street to as few as possible and preferably allow only secondary or collector streets in intersect. Lots may double-front on the major street with the residential street paralleling the major street, thereby resulting in a pattern of development that will, in itself, limit the number of intersections. Secondly, the placement of and distance of curb cuts from intersections can be limited in order to safely channelize traffic from adjoining properties onto the major street. A minimum of 40 feet should be set on curb cuts from the point of intersection, and such curb cuts should not be over 25 feet in length. There should no also be more than one curb cut of 25-foot length in every 100 feet of major street frontage.

WATER SYSTEM
1. INTRODUCTION
The most dramatic development in the municipal water supply field during the 1970's has been the of the federal E.A.P. entry Previously, regulatory activity had been the sole responsibility of the state government. Fortunately for Katy, the E.A.P.regulations apply mainly to surface water supplies such as lakes and with little rivers, immediate effect upon deep well supplies such as Katy's.
Of considerable local importance has been the creation of the Harris Galveston Coastal Subsidence District ( HGCSD)and later the Fort Bend County Subsidence District, with authority to regulate all municipal, industrial, and agricultural water wells in Harris, Galveston, and Fort Bend Counties..The HGCSD is attempting to implement a long term conversion to surface water and the abandonment or reduced use of the areas water wells.
The of is in Area 3 as City Katy defined by the HGCSD and is stipulated to have a ground water reduction and plan prepared approved by 2003. The stipulation goes further in that the City must reduce its groundwater use by 30%by 2010.
The of will need to City Katy regulate the development in its jurisdiction to control the amount of that it utilizes. The groundwater City needs to develop additional water supplies in its westernmost limits. This area is in Waller and at this time has no city county rules controlling groundwater usage. The of the surface majority water in the Houston area is under the direct control of the City of Houston. It is to how the of impossible predict City Houston will cooperate with the outlying areas in the areas dividing up available surface water. As stated above, the City of Katy needs to control the growth in its jurisdiction and all citizens need to practice water conservation.
2. REGULATION
In addition to the E.A.P.and Subsidence Districts, municipal water systems are reviewed and influenced by the Texas Natural Resource Conservation Commission (TNRCC),the Texas Fire Insurance Commission, and the Texas Public Utility Commission. The procedures of the Public Commission are confmed to and user Utility largely billing charges, which are beyond the scope of this the TNRCC and Insurance report. However, Commission each exert a strong influence on municipal water systems. The pertinent regulations are summarized in the following table.
Page -54- WATER SUPPLY REGULATIONS
State Health Department Fire Insurance Commission
Wells 0.6 gpm* /connection 0.3 gpm* /connection
Ground Storage 200 gallons / connection 455 gallons / connection
Elevated Storage 100 gallons / connection 190 gallons / connection
Service Pumps 2.0 gpm* /connection
Gallons per minute
Not applicable
From the above it is clear that the table, Health Department's minimum criteria control the well and service whereas the Insurance pumping capacity, Commission's requirements are more stringent for ground and elevated storage tanks.
Existing Facilities
The City presently operates the following waterworks facilities:
Page -55-
The previous table reflects that Katy's basic water supply facilities are ample at this time. The amount of water that the City water well can produce with one well out of service may be taxed of during long periods maximum demand which may continue for several consecutive days, or even weeks. The TNRCC that the requires City's total well capacity be at least 0.6 gallons per minute per connection. For a city of 12,000 persons with the commercial development that Katy enjoys, this requirement amounts to 3,240 gallons per minute with one well out of service for repairs.
3. GROUND STORAGE
The of is to a of water purpose ground storage provide large supply that the high service pumps may draw of upon during periods heavy demand or during a serious fire. Fire protection criteria are the most important factors in evaluating the need for ground storage facilities. The major requirement is that the 455 City provide gallons of storage per connection. In Katy's case, this requirement amounts to a for necessity approximately 2,000457,gallons. Thus, the present tanks are adequate for the present population.
4. ELEVATED STORAGE
The function of elevated is to storage provide a pressurized water supply during power failures and to for provide short-term surges of demand. Fire insurance rates are increased for cities which do not at least 190 provide gallons of elevated storage for each connection. The TNRCC has a somewhat less stringent requirement. To meet the fire insurance criteria for its present population, Katy needs in approximately 1,000026,gallons elevated storage. Thus, the City has enough elevated storage capacity for its present population.
5. HIGH SERVICE PUMPS
High service (or booster) pumps must be capable of providing fire fighting requirements and simultaneously serving the maximum daily demand. The State Board of Insurance recommends, in their Rate Schedule Key for Grading Cities and Towns, that the City's water system be capable of a delivering 10,800 gpm (gallons per minute)fire flow to the principal mercantile area of Katy. Since the have a combined of present pumps capacity 15,500 gpm, the City has ample high service pumps for the City's present population.
6. WATER MAINS
The City's existing pipe system is generally adequate. It consists of a grid of six-inch and eight-inch lines throughout the City and twelve-inch lines connecting the City's water plants together. The water distribution network must deliver adequate amounts of water at sufficient pressure to serve both
Page -57- peak consumer usage and fire fighting requirements. Long dead-end mains are undesirable, because of stagnation problems and because of the danger of pipe rupture or valve failure which would leave an area without fire protection; thus grids and loops are recommended wherever feasible.
7. FIRE HYDRANTS
fire Katy's hydrant inventory generally meets the basic criteria for insurance purposes. All hydrants are served from six or eight-inch mains and are full-size, standard units. Present criteria requires that the distance between fire hydrants be no greater than 600 feet and that every residence be within 500 feet of a hydrant.
8. MAP REFERENCE
The map titled "Water System" at the end of this chapter should be used in conjunction with the following projections of future system requirements.
9. PROJECTED WATER SYSTEM REQUIREMENTS
The table following shows the City's projected water system needs based upon the population estimates presented earlier in this report. A population of 3.25 persons per connection is used in all following calculations. The table can be used to compute the additional facilities needed during each five-year period considered in this report.
Page -58-
10. FACILITY SUMMARY
The capital improvements program outlined in the preceding Tables reflect the need for four new water plants during the twenty-year period preceding 2020 A.D. Each such plant would eventually include supply (well),storage, pumping, and transmission facilities. The map titled "Water System Plan" at the end of this chapter shows general locations for the new water plants. It should be emphasized that the location of the plants is extremely flexible and can usually vary from the map by as much as a mile without changing the basic concept of this chapter.
Page -61-
3. EXISTING FACILITIES
Katy's sewerage system consists of a central treatment plant south of the developed part of the City with sewers northward to branching serve the existing build-up area. The principal sewer pipes and plant location are shown on the map titled "Sanitary Sewer Plan" at the end of this chapter.
4. SEWAGE TREATMENT
The treatment sewage plant was put into operation in 1969 with an initial capacity of 0.75 million gallons per Its was increased in 1979 and day. capacity again in the early 1990's,but under the more effluent limitations stringent mentioned previously, its current capacity is estimated to be 1.800 million gallons per day.
The the plant employs contact stabilization process, a member of the activated sludge treatment family. In this diffused air is used to distribute system, oxygen and mix the sewage and sludge. of Twenty years operating experience have shown that the plant can meet its permit requirement wet when except during weather, excessive rainwater enters the collection system. The physical of the arrangement existing structures does not lend itself to simple modular additions in the future. It is recommended that future should enlargements consider another arrangement that is more to economical The adaptable expansion. City of Katy is in the process of acquiring additional at the property sewage treatment plant which will allow for the plant to be expanded for ultimate build-out for the City of Katy.
5. SEWAGE COLLECTION
collection has Katy's sewage system undergone several major extensions in the past. Presently, it serves the central and eastern portion of the City, but will need additional major expansions in order to serve the far northern, western, and southern portions of the City's jurisdiction.
Accurate land-use estimates are difficult to foresee, yet land use is the principal factor in projecting future sewer demands. For the example, sewage flow from an apartment area may be twenty times greater than if the same area were as an developed office-warehouse complex. A sewer planned in advance of such is development always in jeopardy of being too large or too small.
The major sewers shown on the MAP titled " Sanitary Sewage Plan" at the end of this chapter are based an upon average population density of twenty persons per acre. Such an estimate is somewhat than most higher single family residential areas and lower than most multi-family developments. Where indications exist that strong planning is currently underway for a vacant tract, then that intended use has been considered in the sewer estimates.
Page -65- 6. SANITARY SEWERAGE PROJECTIONS
The sewers for the ultimate of the major projected development planning area are shown on the map titled " Sanitary Sewage Plan" at the end of this chapter. No schedule has been proposed for construction of the sewers because unpredictable development events will control the actual need for extensions into vacant areas. utility However, the schedule for sewage treatment expansion can be correlated to the The projected population growth. following Table shows the resulting sewage treatment requirements for the planning period.

STORM DRAINAGE SYSTEM
1. PRESENT STATUS
The City of Katy has land in its E.J.T.that is in three different counties and three drainage districts. The area largest and the majority of the population in Katy are contained in Harris County and Harris Flood Control County District. Harris County Flood Control has the most experience of the drainage districts. Their rules are ones the the City of Katy has adopted. The area of the City that is contained in Harris County is on the east and north sides of the city.
The area on the south side of the City of Katy is mainly co/mnercial and falls under the jurisdiction of Fort Bend Flood Control. County Fort Bend County Flood Control has its own separate rules and regulations but has cooperated fully with the City of Katy on all projects.
The western area of the City of Katy falls in Waller County and includes both residential and commercial areas. The line between Waller County and Harris County generally follows Cane Island Branch of Buffalo in a Bayou northwest direction from the tri-county monument located in the downtown area. That portion of the City of Katy that lies within Waller County is also in the Brookshire-Katy Drainage District. This area, together with the City of Brookshire contains the of the of majority population the Drainage District. The Brookshire-Katy Drainage District also has promulgated rules for land that falls in its jurisdiction.
Since the Comprehensive Plan was adopted in 1980, detention has come to the forefront for all in the development Houston area. Individual detention ponds on small tracts of land have faded from favor and have been generally replaced by larger regional detention ponds maintained by one of the public entities.
2. SUBSEQUENT DEVELOPMENTS
In 1968, Congress created the Federal Insurance Administration (FIA)and provided for subsidized flood insurance. In 1973, dissatisfied with its lack of acceptance by the nation's communities, the Flood Disaster Act Congress passed Protection of 1973. Until that time, flood insurance was to obtain at a reasonable impossible price. The City adopted the FIA program in 1974 in order to allow its residents to acquire subsidized insurance. The City received their official flood insurance map in 1983.
3. HARRIS COUNTY PLANNING
As shown on the attached drainage area maps, most of the developed area of Katy is within Harris County, which addresses flood control planning through its Harris County Flood Control District.
Page -69- The District, a separate but not independent agency of the county government, has had its budget reduced significantly since the 1980 Comprehensive Plan was drafted. There have been few flood control in improvements implemented the Katy area of Harris County since 1980. The one exception was the work that Harris County Flood Control did in the early 1980's along the railroad ditch in Katy.
Harris County and Harris Flood Control do have County plans for significant improvements on the east side of Katy in the future. The of has to City Katy agreed furnish in excess of 200,$ 000 for right- of-way for the new ditch which will intersect Katy-Hockley Cutoff Road half way between Morton Road and Franz Road. Harris County's flood control designation for this extension of Mason Creek is Ti01-00.00-The Harris channels that are County planned are shown on the following map.
4. OTHER AGENCIES
Although the programs of the FIA ( and Harris F.M.E.A.) County have had the greatest impact on Katy's drainage situation, other entities also governmental have jurisdiction and may have an increasing future influence.
Waller As shown in the County. attached map, Cane Island Branch bisects most of Katy's jurisdiction. Thus, flood control proper planning for Cane Island Branch is vital to Katy's interests. as noted However, above, the majority of the drainage area of Cane Island Branch lies outside the of jurisdiction Katy, and development will be controlled by Waller County and the City of Houston. It is absolutely necessary that Waller County, which currently has no published for this be drainage plans area, encouraged to develop land planning - drainage that are consistent regulations with those of Katy, Harris County, and the other jurisdictional entities.
Ci_ty of Houston. Houston's Extraterritorial Jurisdiction (E.J.)T.surrounds that of Katy and includes large areas in Waller and Fort Bend as Counties, well as the Harris County area east of Houston's land Katy. development policy requires that developers obtain the endorsement of the in applicable county matters of drainage and other construction plans. Such control will benefit if the Katy county has a drainage plan and regulations consistent with Katy's interests.
Fort Bend Most of County. Katy's economically important freeway area is in Fort Bend County. A substantial of this area is portion within the FIA's 100-year flood zone. Thus, it is extremely important to Katy that flood planning in this area be consistent with its interests. Fortunately, the natural have most of their area drainage ways within Katy's jurisdiction, so that the can exercise City direct control over their drainage development. Also, Fort Bend has maintained a County long flood control engineering department which, while less formal and extensive than that of Harris County, has actively promoted drainage planning and regulation.
Page-70- Do Brookshire - District. This Katy Drainage agency operates principally in the area between Brookshire and Katy, maintaining drainage ditches which serve municipal and agricultural interests. Cane Island Branch above the tri-county junction and other lesser channels westward benefit from the District's maintenance program. At this time, the District has no full time staff but does engineering require developers to furnish plans for review and to construct detention.
Transportation Agencies. The Texas Department of Transportation maintains U.S.Highway 90 as well as through Katy Interstate Highway 10. The M.T.K.Railroad operates its main line parallel to Highway 90. The existing bridges and culverts under Highway 90 and the railroad will require enlargement, mandating the assistance or,at least, cooperation of their respective owners.
5. REGIONAL DRAINAGE
The discussion of previous drainage agencies indicates that Katy must secure considerable inter- in order to governmental cooperation protect the flood control interests of its residents. However, further reference to the " Regional Drainage Map" shows that the bulk of the drainage which eventually could flow into the area comes from Katy Waller County. Therefore, it is absolutely essential that Waller a County develop drainage plan and regulations similar in concept to the Harris County plan referenced previously.
The " Area also Drainage Map" suggests a relationship with the Cypress Creek Watershed to the north of the area. It seems Katy probable that excess rainfall on this watershed produces overflows which travel southward into the Katy area. Again, since the area of Cypress Creek in Waller County seems most critical to from Waller Katy's drainage, cooperation County is absolutely necessary.
The City of has made a forward in Katy major step getting cooperation with the three drainage districts with of the adoption drainage plan the City recently completed. As mentioned previously, the plan was drafted Dodson and Associates and by used previous data from the F.M.E.A.studies, information from Harris Flood County Control and information from Brookshire-Katy Drainage District in the The also completing report. report contains an updated computer model that can be used by the the District and to City, Drainage developers qualify the effect any improvement will have on the flood The 100-year plain. report shows that a large amount of the water that comes the of through City Katy during flood events is water that overflows from the Cypress Creek watershed.
Page -71- 6. DESIGN CONSIDERATIONS
The basic design criteria used in this chapter are consistent with the criteria used by Harris County and the City of Houston. Such consistency will allow a uniform basis for interagency and regional planning.
Peak Flow versus Watershed Development. The Harris County Flood Control District has determined that peak flows from a watershed more than double after full development when compared to the same area in an undeveloped condition. The District has further observed that total runoff may not be much greater after development than before. The first determination seems correct for the Katy area; however, the second observation is probably not as accurate for most of Katy because the top soil has a greater permeability and porosity than much of the Houston area, which causes an increase in total runoff after development.
Watershed Four Development. types of storm water conveyance structures are used in municipal drainage:
Sewers such as pipes or boxes,
Bridges,
Unlined (earth)channels,
Lined (concrete) channels.
For unlined it is channels, sometimes possible to initially construct a narrower ditch than will be ultimately necessary. However, sewer, bridges, and lined channels must almost always be installed at their ultimate future size. For these reasons, and because predicting the pattern of vacant land development is impractical, all drainage improvements have been designed for full watershed development.
Flood refers to Frequency. "Frequency" the average period between flooding of a certain degree. In terms, a flood one simplified 25-year frequency is which would occur an average of once in a 25-year period. Storm drainage design in the Houston area has generally used the following frequency considerations:
Two to Three Year Frequency - Storm sewers flowing full but minimal street ponding.
Six to Ten Year Frequency - Nuisance street flooding at some locations.
Year Twenty-five Frequency - Major channels flowing full with widespread street flooding, but no major property damage.
Page -72- Several notes of caution are necessary when reviewing the above frequency considerations. The statements apply better to new construction where street and drainage are designed together for construction of drainage systems for existing developed areas. Second, there is no that several guarantee storms of twenty-five year frequency or more will not occur in the same year. Finally, lack of downstream improvements can create bottlenecks which reduce the good effects of upstream construction.
Runoff Rates. The peak rate of runoff is the flow condition for which storm sewers, culverts, and channels are Peak runoff designed. is determined by the type of development and the area under consideration. For consistency, the diagrams published by Harris County Flood Control District in its "Comprehensive Study of Drainage for Metropolitan Houston - Section VIII - Buffalo Watershed Bayou above Addicks and Barker Dams"are adopted for use in this chapter. The referenced diagrams constitute Figures 6, 7, and 8 of the District's study, and are tabulated below:
MAXIMUM DISCHARGE (C.S.)F. AREA RESIDENTIAL COMMERCIAL
10 acres, or less 15 20
20 acres 27 36
50 acres 67 89
100 acres 134 178

In steeper general, open channels are rarely placed beside a roadway because the is adjoining property partially severed from access to the road. However, such an allows of maintenance and alignment facility should not be objectionable when the property owner is agreeable.
8. POLICY RECOMMENDATIONS
As mentioned in the first sections of this chapter, the City of Katy does not control large sections of the watersheds which affect the City's drainage. It was emphasized that interagency cooperation with Harris County, Waller County, Fort Bend County, the City of Houston, and other drainage-related entities is necessary to protect Katy's interests. Therefore, it is strongly recommended that Katy flood encourage planning policies among its neighboring governments that are consistent with the City's goals.
In order to gain the above desired cooperation, it is necessary for Katy to set the example within the area over which it does exercise control. None of the existing major drainage channels (Cane Island Branch, Snake Creek, Buffalo Bayou, for example) have adequate channel capacity for ultimate development of their watershed. Therefore, either extensive channel improvements (and right-wayof- acquisition) are necessary or the runoff must be restricted. For future development within Katy's jurisdiction (E.J.),T.the City must choose between one of the two following policies:
Channelization Policy. The City of Katy would serve as escrow agent for a special Drainage Fund. Each developer would contribute an amount of money to the fund equal to the cost of the downstream channel and right-wayof-improvements made necessary by his proposed construction. these Using funds, the City would make the necessary improvements. This policy would apply mainly to Cane Island Branch, Snake Creek, and Willow Fork, but could be used to develop new major channels where the City felt its best interests would be served.
Under the above a policy, developer whose land does not have access to one of the existing channels should be major allowed to construct detention ponds as a temporary measure,
Page-74- similar to the Harris County "Interim Drainage Policy" discussed previously. However, the normal contribution would be required so that the ponds could be discontinued when access becomes available.
Retention All would be Policy. developers required to construct detention ponds except:
a. Small projects, such as three acres or less.
b. For residential where the is not single-family projects density more than one residence per five acres.
Under this policy the detention ponds would be permanent facilities.
The above two Policy Development. alternative policies are basic concepts. Considerable legal and economic details would have to be worked into the final policy ordinance.
Recommendation. Policy The detention policy allows developers to proceed with their with minimum projects administrative difficulty for the City. However, the "perpetual care" aspects of maintaining pumps, motors, levees, ponds, and landscape presents a permanent for the as well as responsibility City the developers. For example, even if the developer remains for the and related responsible ponds equipment, the City must maintain a vigilance to insure that the facilities are in working order. Complaints about pond nuisances, public health, and safety conditions are also likely to fall on the City.
In the taking long-range view, permanent detention ponds do not seem justifiable. It is recommended that the City adopt the "Channelization Policy"discussed previously, and that detention ponds be considered only as temporary conveniences to the developer.
9. CONSTRUCTION RECOMMENDATIONS
The and considerations were preceding design policy applied to each drainage area with a view toward approximating the necessary storm sewer and channel requirements for ultimate development. Since the must a of either City adopt policy making major channel improvements or of allowing to use developers detention ponds, it is impossible to calculate in advance which option will be exercised. Because there is a significant difference in the discharged from each option, the proposed drainage systems were evaluated based upon both the detention and no-detention alternatives. The low is density option expected to generate approximately the same runoff as the retention pond option.
Page -75- 10. REGIONAL DETENTION
The of commissioned a City Katy study for flood protection planning in 1995 that was funded by the Texas Water Board. Development The purpose of the study was to formulate a flood protection plan for the of City Katy by studying the existing conditions of the watersheds and to review future Also included in development projections. the study was a draft revenue generating plan to fund the proposed flood facilities. The protection report recommended that the City of Katy construct regional detention facilities in lieu of multiple small detention ponds. This would give individuals building on one lot or with small developers acreage the option of paying a drainage assessment fee for the City to construct detention instead of regional constructing their own small, onsite detention pond. The study concluded that the cost of providing regional detention for the City of Katy was $2,00500. acre for each acre per developed. The City Council of Katy accepted this recommendation and the fee was included in a city ordinance.
In 1999, the of started the of City Katy process acquiring the first tract for a regional detention pond. A contract to acquire approximately forty-eight acres west of Cane Island Branch and north of Morton Road was to the for this agreed by City purpose. Part of the study by Dodson and Associates was the evaluation of this site. Their conclusion was that the construction of the detention pond at this site would offset the of development 250 - 300 acres of single family residential development. The of process acquiring the site and planning for construction are on-going at this time.

ZONING
As stated in the development section of this plan, zoning was implemented in the City of Katy in 1983 after a positive vote of the citizens. At that time, the Comprehensive Plan was updated to reflect zoning and slight revisions in the subdivision ordinance.
has been in effect in for a Zoning Katy period approaching twenty years and has been a valuable tool. The current planning zoning map is included as part of this report. As problems developed, several minor have been made in the changes zoning ordinance in the past years. A copy of the ordinance is available at the Office of zoning Municipal the City of Katy. The zoning map and ordinance have been invaluable to potential property owners informing them of the proposed use of the property they plan to acquire.
There have been several "Planned Development Districts" PDD)( formed in the City of Katy since zoning was implemented. The newest PDD formed has been the creation of the Mills Mall. This project covers 640 acres and has been a tremendous boost to the City of Katy.
After nearly twenty years, even former opponents of zoning in the City of Katy have admitted it has been a success. in has Development Katy been orderly and controlled with very few problems.
