The primary purpose of this planning program is to provide a practical' framework for developing a healthy and desirable community, in light of the increase in growth caused by the effects of new and expanded coastal energy activities in the City of Ingleside and the surrounding areas. This report is divided into four (4) major planning units, which include MASTER COMPREHENSIVE PLANS and PRELIMINARY COST ESTIMATES to update the following: UNIT ONE: WATER STORAGE AND PUMPING FACILITIES UNIT TWO: WATER DISTRIBUTION SYSTEM UNIT THREE: SANITARY SEWER COLLECTION AND TREATMENT SYSTEM UNIT FOUR: STREET AND DRAINAGE SYSTEM This summary report addresses itself to answering the following questions for each of the four planning units: A. How effective is the existing system? B. What SHORT RANGE EXPANSION can the existing present system adequately handle in the immediate future? C. What LONG RANGE EXPANSION can be incorporated with the present and SHORT RANGE EXPANSION? I I I I I I I UNIT ONE I I WATER STORAGE AND I PUMPING FACILITIES I I I I I I I I I UNIT ONE: A. GENERAL COMMENTS AND RECOMMENDATIONS Ingleside receives fresh water from the San Patricio Water District. The water is delivered to Ingleside ground storage facilities and pump station from a 12-inch lateral.from an 18-inch main line that also serves the cities of Aransas Pass, Port Aransas, Rockport, etc. The district has two (2) major transmission lines from City of Corpus Christi and Calallen Water Treatment Plant, one a 24-inch treated water line with a capacity of 8.5 million gallons per day and the other a 36-inch main water line with a capacity of 18 million gallons per day, in addition to the water treatment plant adjacent to Reynolds Metal Company that has a capacity of 3 million gallons per day. The City of Ingleside has two pump stations with ground storage facilities and one elevated tank. 1. Pump Station No. 1: The older of the two, has a 400,000 gallon ground storage tank and a pump station that has two distribution pumps, one with a capacity of 500 gpm with 150 feet head and one with a capacity of 1,000 gpm with 160 feet head, with the differential in heads both pumps can not operate together. The operation of the pumps are controlled by a mercaroid pressure switch located at the elevated water storage tank and connected with a telephone line for transmission of the signal be- tween the tank and the control panel of the pumps. This pump station is located at California and Waco Streets. RECOMMENDATION: That this pump station be renovated to include the installation of a new 2,500 gpm pump and complete overhaul of the two existing pumps to be utilized for low-flow or stand-by units. The installation of a control system linking this pump station with the elevated storage tank and pump station No. 2 to insure system-wide volume and pressure control response. Immediate initiation of an investigation to deter- mine the feasibility of the supply lead and meter to be increased to a 10" minimum, incorporating volume/pressure automatic controls to insure mini- mum pressure drops or surges to the San Patricio Water District's system. 2 2* Station No. 2: The new station has been constructed in 1979 and consists of a 200,000 gallon ground storage tank, two pumps, one with a capacity of 500 gpm/160 feet head and the other with a capacity of 1,250 gpm/160 feet head complete with all necessary controls. This station has a 6-inch supply line from the district. RECOMMENDATION: immediate initiation of a joint study with the San Patricio Water District to determine the short range feasibility to increase the supply lead and meter to a 12" minimum. To reserve the required land area at the present 20 acre city tract at Pump Station No. 2 to insure expansion in unit modules of the ground storage capacity. Initiate efforts to increase existing pumping capacity by utilizing an additional 2,500 gpm. PUMPS- 3, Water Storage: The total water storage for the City consists of three tanks as follows: a. 400,000 gallon steel (ground) tank; b. 200,000 gallon steel (ground) tank; C. 250,000 gallon steel (elevated) tank; For a total storage capacity of 850,000 gallons. The San Patricio Water District requires a minimum total storage of the peak daily use and in Ingleside this would amount to a minimum of 1,500,000 gallons total ground and elevated storage. RECOMMENDATION: Initiate efforts to expand the ground storage at Pump Station No. 2 to 1.2 million gallons. 3 UNIT ONE: B. DEVELOPMENT OF MASTER PLAN The following are assumed guidelines used in formulating this Master Plan: 1. General: That the purpose of water storage in a distribution system is to increase the capacity and capability of the distribution system to: a. Meet the water demands required for fire fighting. b. Meet the maximum hour demands caused by summer peak consumption. c. Provide more uniform pressures 24 hours a day. d. Reduce the effects of water hammer and prevent the rupturing of mains and service due to excessive pressures. e. Provide water to meet the distribution system demands when source of supply is temporarily reduced for short periods of time. f. Make it possible to have more flexible operation in the system. Also, that storage requirements are influenced by four factors: a. By the ratio of maximum hour to the average day demand. b. The ratio of maximum hour to the maximum day demand. c. The amount of reserve storage recommended to be available to meet maximum fire flow requirements. d. The reliability of the supply and pumping equipment. 2. Short Range Expansion- That the San Patricio Water District has the capacity and distribution system to handle the expected flows. That the two existing pump stations can continue to be utilized and incorporated into the short range expansion. That the upgrading of the pumping facilities may be accomplished with no interruption of city-wide service. That the available sites of the present ground storage may be utilized to their optimum. 4 3* Long Range Expansion: That the San Patricio Water District will have the capacity and distribution system to handle the expected flows. That the best arrangement is to have the source on one side of the system and the elevated storage on the opposite side. This, in effect, doubles the capacity of the system to meet maximum demands and provide water for fire fighting purposes. That direct controls can be placed in all elevated storage so that the pumping equipment at the source can be operated entirely automatically as needed to supply the system. That the required sites for the elevated storage can be acquired through normal land acquisition. 5 UNIT ONE: C. PRIORITY SEQUENCE AND PRELIMINARY COST ESTIMATES Immediate Up-Grading: 1.

GENERAL COMMENTS AND RECOMMENDATIONS The City of Ingleside's Water Distribution System within the city limits is generally in fair condition, except for a few deficiencies as follows: 1. Highly populated areas presently with fire main pressure and volume, not having fire hydrant access. RECOMMENDATION: Immediate initiation of a FIRE HYDRANT SUPPLEMENTRY INSTALLATION PROGRAM to be incorporated with the City's normal operating budget. This program should be completed within the next two to four years. 2. Existing old cast iron and galvanize iron service lines which due to corrosion build-up and deteriorated condition are causing low volume and pressure in the distribution system network. RECOMMENDATION- Immediate initiation of a SERVICE LINE REPLACEMENT PROGRAM to be incorporated with the City's normal operating budget. This program should be completed within the next five to six years. 3. Existing service lines still in good condition but with low volume and pressure in the distribution system network. RECOMMENDATION: Initiate a MINOR LINE EXTENSION PROGRAM to extend and loop existing dead end service lines to be either incorporated in the City's normal operating budget or contracted out to private contractors. This program should be completed within the next two to three years. UNIT TWO: B. DEVELOPMENT OF MASTER PLAN The following are assumed guidelines used in formulating this Master Plan: 1. GENERAL: The investigation of the present Water Distribution System consisted of first gathering any existing filed information and compiling the information into a system map. A comprehensive field verification effort with the aid of City Staff produced the existing Water. Distribution Map of Ingleside. The distribution system was divided into sub-systems which could be studied for volume and pressure charac- teristics, where problem areas were isolated and identified. The distribution system Main lines were catergorized as to present pressure and volume capacity to determine if areas not presently under Fire Hydrant coverage could be up-graded to normal City standards. 2. SHORT RANGE EXPANSION: a. Extension of existing system may occur only ifthe.supply, storage, and pumping facilities serving the proposed expansion have the capacity to handle the expected future f lows. b. Major distribution loop lines (pressure and volume equalizers) will receive top priority, to insure maximum utilization of the existing supply and distribution system at minimal capital investment resulting in highest cost-effectiveness. c. The existing developed residential areas within the existing distribution system will receive priority over undeveloped industrial areas. 3. LONG RANGE EXPANSION: a. That all undeveloped areas within the City limits will have residential population density equivalence consumption. .b. That major distribution trunk line (pressure and volume equalizers) to interconnect elevated and ground storage facilities will receive priority. C. That loop lines to minimize service interruption and low pressure and volume, will also receive top priority. 9 UNIT TWO: C.

GENERAL COMMENTS AND RECOMMENDATIONS The sanitary sewer collection system is overall in fair condition except for the following: a. Infiltration/inflow into the system causes surcharge conditions and treatment plant overloading during wet weather periods. RECOMMENDATION: Immediate initiation of a collection system investigation to locate and reduce infiltra- tion/inflow during wet weather periods, in- cluding a Closed Circuit Television investi- gation of major 15" trunk lines of the following: 1. Sixth Street from Avenue "D" to Avenue "B". 2. Avenue "B" from Sixth Street to Seventh Street. 3. San Angelo Street from Mustang Street to the lift station. 4. Oklahoma Street from Avenue "B" to San Angelo Street. 5. Trunk line south of Oklahoma Street from Avenue "B" to the lift station. Immediate initiation of cleaning wetwells and renovation of pumps and equipment in sub-lift station. Immediate initiation of cleaning and making necessary equipment repairs to treatment plant. 2. Only limited short range expansion can adequately be handled by the present sanitary sewer collection and treatment system if the deficiencies above are correct. RECOMMENDATION: Installation of new collector and lateral lines to provide immediate service to the following streets: PHASE I: 1. Fourth Street east of Avenue "A". 2. Alley between Avenue "A" and Benito Juarez south of Fourth Street. 23 3. Alley between Benito Juarez and Garza Avenue south of Fourth Street. PHASE II: 1. First Street west of Avenue "A". 2. Buckeye west of Avenue "A". 3. Chandler Place east of Avenue "A". 4. Azalea Avenue north of First Street. 5. Honeysuckle Avenue north of First Street. PHASE III: 1. Avenue "I" from Fourth Street to First Street. 2. Third Street east of Avenue 11119. 3. Avenue "J" north of Fourth Street. 4. Avenue "K" north of Fourth Street. 5. Alley between First-and Second Street east of Avenue "I". 6. First Street east of Avenue "I". 7. Buckeye Drive north of First Street. PHASE IV: 1. Sixth Street from Poinsetta to just past Henrietta. 2. West of Henrietta from Sixth Street to Eighth Street. 3. East of Henrietta from Sixth Street to Eighth Street. 24 RECOMMENDATION: Installation of a 12" collector line from.Eighth Street to serve area east of Belair Subdivision. RECOMMENDATION: installation of a 12" collector line on Sixth Street and a 10" collector line to serve an area between Big Oak and Avenue "A". Also an 8" lateral line on Greenbriar Drive from Sixth Street south to Eighth Street. 3. The long range expansion for providing tewer service to areas north of the Southern Pacif ic Railroad tracks can only be accompanied by the addition of a new wastewater treatment facility. RECOMMENDATION: In reviewing studies and reports by others, a new wastewater treatment facility is more feasible than the proposed Land Treatment Method. 4. This preliminary investigation found that the existing treatment plant will not be able to handle future growth of the City, other than that shown for short range expansion. There are also some of the major collector lines already flowing at full capacity. There is no available land in the imme- diate area of the existing plant due to the increase in energy related industries. The natural ground at the existing plant site is 10.0 feet above mean sea level to approximately 14.0 feet above mean sea level and the ground water table varies between 3 to 6 feet below natural grade. The proposed treatment plant would be located south of E ighth Street between Avenue "B" and Avenue "G". This proposed site has ample room for expansion. The.proposed plant would be large enough to handle future growth and also to divert two-thirds of the existing flow through a24-inch interceptor line. The proposed interceptor line would start at the new plant and go along Avenue "D" to Sixth Street and intercept and connect to the existing system., 25 UNIT THREE: B. DEVELOPMENT OF MASTER PLAN The following are assumed guidelines used in formulating this Master Plan: THE COLLECTION SYSTEMS: I. General: The investigation of the present Wastewater Collection System consisted of dividing the existing system into sub-systems which could be studied for maximum flow characteristics of the main collector lines, maximum flows expected and area served. The outer most system collectors were studied for depth for future extensions and for collector flow capacity limitations. Some of the sub-system collector lines that were found to be surcharged were hydraulically checked for maximum flow capacities. 2. Short Range Expansion: a. Extension of the existing system may occur only if collector lines, lift stations and treatment facilities serving the proposed expansion have the capacity to handle the expected future flows. b. The existing developed residential areas within the City limits and within or close to existing systems will receive top priority. c. No areas outside the City limits will be considered because of numerous areas within the City limits without sewer service. 3. Long Range Expansion: a. That all undeveloped areas will have residential population density equivalence or less, in order to estimate probable flow concen- trations. b. The natural physical land limitation such as railroads, highwayst natural slope of undeveloped land will have direct priority for sub-systems. c. That boundaries of each sub-system in undeveloped areas are subject to change depending on which area develops first and unforseen physical limitations, however, the total acreage of each sub-system should not be increased. 26 THE WASTEWATER TREATMENT FACILITIES: 1. General: The investigation of the present wastewater treatment facilities consisted of evaluating-and studying existing reports and records and consultations with field personnel. 2. Short Ranqe Expansion: a. The wastewater treatment capacity be reserved for existing residential areas not yet fully developed and for new sub- divided areas not yet fully occupied.. b. That the present wastewater treatment complex be utilized to its ultimate efficiency by replacing old inefficient plant equipment with new equipment. 3. Long Range Expansion: a. That required land aquisitions, easements, and right-of-ways can be obtained through owner negotiation and/or condemnation as needed. b. That all undeveloped areas will have residential population density equivalence or less, in order to estimate probable flow concentrations. 27 GENERAL DESIGN CRITERIA 1. Assume - 2.6 lots per acre 2.

GENERAL COMMENTS AND RECOMMENDATIONS (Street Segment) The street segment of this report focused on two objectives, one, the development of a transporation and circulation plan for traffic flow and two, the development of a Seal and Reconstruction Street Program. TRANSPORATION AND CIRCULATION PLAN: The development of an effective traffic system has been hampered by the limited public right-of-way widths within the City and surrounding areas. RECOMMENDATION: Immediate iniation of a State, County and Local effort to acquire additional right-of-way now, prior to any additional private build-up along proposed routes. SEAL AND RECONSTRUCTION STREET PROGRAM: Under normal circumstances where the condition of the street system varies from excellent, good, fair, needing repiar, to needing re- construction of a Short Range Improvement and Maintenance Program may be outlined in a manner that the City can incorporate it as an I ordinary budget item over a sequence of years to emcompass the entire City street system. But when the entire street system is in such a deteriorate stage needing immediate city-wide repair, it is impossible to prioritize any program in a logical order. Therefore, only a phase grouping of streets have been outlined, and this phase grouping should not be confused as a priority list at this time. RECOMMENDATION. Immediate intiation of Seal and Reconstruction of streets in areas where simple drainage has been provided, to insure optimum cost-effective- ness of work. 36 UNIT FOUR: B. DEVELOPMENT OF MASTER PLAN (Street Segment) The following are assumed guidelines used in formulating this segment of the Master Plan: TRANSPORTATION AND CIRCULATION PLAN: 1. General: In most basic classification system for design work, streets and highways are grouped into four (4) general classi- fications, (a) highways, (b) thoroughfares, (c) collector streets, and (d) local or minor streets. These classifications usually carry with them a set of suggested design standards which are in keeping with the importance of this system, and are governed by specific transportation service the system is designed to perform. The four (4) basic types of urban street classification systems as discussed above are outlined in greater detail as follows: a. jj@wa@s: Provides for expeditious movement of large volumes of traffic between areas and across the city. b. Thoroughfares: Provide for the through traffice move- ment between areas and across the City, and incorporate direct access to abutting property within the system. c. Collector streets: Provides for traffic movement between thoroughfares and local streets, as well as direct access to abutting property. Collector streets normally collect the majority of traffic originating within the residential areas and distribute this traffice to various points along the route, or chan- nelize it to a major thoroughfare.- d. Local or Minor Streets: Provide direct acess to abutting land and for local traffic movements. An important function of the minor street is that it services a group of residential units with limited traffic demands and should not be considered nor utilized in a collector capacity to channel traffic to other land use areas. 37 2. SHORT RANGE EXPANSION: The following assumed guidelines were utilized: a. That street condition of existing minor streets shall basically be improved within the next five (5) years. b. That adequate drainage will accompany the street con- dition reconstruction. c. That adjacent land required for additional right-of-way can be obtained to normal channels, with minimum delays. 3. LONG RANGE EXPANSION: The following assumed guidelines were utilized: a. That traf f ic flow would continue to increase at normal national averages in similar land use. b. That State, County, and Local governments would joint efforts and formulate a detailed segmented traffic flow and arterial systems to complement this basic plan. 38 SEAL AND RECONSTRUCTION STREET PROGRAM: 1. General: Due to the severe damage the city-wide street system encountered during the September 1979 major flooding. The only factor considered were as follows: a. Complete budgeted normal seal coating and reconstruction of pre-scheduled streets. b. To begin and reconstruct isolated sections of town in order to give maximum relief to populated areas. c. To group schedule reconstruction of streets in order to complete city areas in the most cost-effective manner. 2. This segment addresses.itself only to suggesting phases of work groupings to be reconstructed in a short range improvement pro- gram for Seal and Street Reconstruction. No other short or long range construction programs were formulated under the scope of this report. 39 UNIT FOUR: C. PRIORITY SEQUENCE AND PRELIMINARY COST ESTIMATES (Street Segment) The Preliminary Cost Estimate to correct the deteriorated condition of the existing streets within the City of Ingleside as a direct or indirect re- sult of the September 1979 Major Street Damage due to the prolong flooding experienced at the time is as listed below: The intent of this phase sequence and preliminary cost ranges is to set a base as to the magnitude of the required seal or reconstruction program. PHASE 1 $250,000 to Approx. $300,000 PHASE 11 $175,000 to Approx. $225,000 PHASE 111 $125,000 to Approx. $175,000 PHASE IV $150,000 to Approx. $200,000 PHASE V $250,000 to Approx. $300,000 it is beyond the scope of this report to itemize the program any further due to the urgency of the needed repairs. 40 UNIT FOUR: A. GENERAL COMMENTS AND RECOMMENDATIONS (Drainage Segment) The City of Ingleside's present drainage system can be evaluated as highly lacking the necessary capability to carry off storm run-off effectively as was noted during the recent September 1979 Major Flooding. The San Patricio Drainage District provides the main outfall systems to the City of Ingleside. There are two main outfall systems presently utilized by the City of Ingleside and they are: 1. The McCampbell Slough Outfall: This District's outfall system has recently been improved in depth and capacity. The system provides outfall drainage to the McCampbell Slough Water-Shed which includes most of the northern land area of the city. 2. The Kinney Bayou Outfall: This District's outfall system is pre- sently been processed for improvements, with Corps of Engineers clearance only final right-of-way acquisition remains. The system provides outfall drainage to the Kinney Bayou Water Shed which includes most of the original populated southern section of the City. There are a variaty of existing deficiencies which need concentrated joint State, County, and Local efforts in order to effectively provide an acquire- able solution to the lack of drainage relief to the City of Ingleside. McCampbell Slough Water Shed: The recent improvements to the lower sections of the outfall for this water shed has made it obvious that efforts should be concentrated on improving the remainder of the main outfall collector system. RECOMMENDATION: Immediate initiation of concentrated joint effort to reduce the hydraulic head cost and improve the volume capacity of the F.M. Highway #1069 and F.M. Highway #361 highway structures. Also, concurrent initiation of land right-of-way acquisition vital to the upstream extension of the present outfall system. That a time table be coordinated jointly with the Texas Department of Highways and Public Transportation, San Patricio Drainage District and the City of Ingleside to insure a timely positive continuous effort towards a workable solution. 41 Kinney Bayou Water Shed: The poor unconfined drainage unit, on the lower outfall system and coupled with the highly inefficient highway crossing of F.M. Highway #1069 and Ave. "G", and heavily vegetated ditch section along Ave. "G" makes this water shed system function in its poorist state. RECOMMENDATION: Also, immediately initiate a concentrated effort to assist in the acquisition of the much needed drainage right-of-ways south of Eighth Street. To join together with the San Patricio Drainage District and the Texas Department of Highways and Public Trans- portation to improve the flow and hydraulic character- istics of the Highway crossing at Ave. "G" and F.M. Highway #1069. 42 UNIT FOUR: B. DEVELOPMENT OF MASTER PLAN (Drainage Se2jent The following are assumed guidelines used in formulating this Master Plan: 1. GENERAL: That the purpose of a well defined drainage system is to allow relief to existing flood prone areas and to allow initial development on well drained land. That outfall systems under the jurisdiction of the San Patricio Drain- age District would be phased to coincide with the overall system. That the Texas Department of Highways and Public Transportation would also join efforts, along with the City of Ingleside and the San Patricio Drainage District, to insure proper drainage systems within the study area. 2. SHORT RANGE EXPANSION: That through the joint efforts of the State, County, and City, meaningfull up-grading of the outfall systems would occur as soon as possible. That hydraulic gradiant elevations would be set to insure that the water level of the system remained below natural ground where ever possible to minimize wide-spread flooding. That the City and County would acquire the necessary drainage right- of-ways through normal procedures with little time delays. That minor existing system laterals may be up-graded to include re- grading and maintenance to insure proper drainage as the outfall system is completed. 3. LONG RANGE EXPANSION: That when proper drainage facilities are constructed along with initial development, the systems are usually simple and inexpensive. That bad drainage increases the cost of street maintenance, as standing water or prolonged periods of flooding conditions causes extensive damage to base and apshaltic surfaces of streets. That bad drainage also tends to overload the sewage collection system and the sewage treatment plant. That natural drainage flow direction would take priority were ever possible. 43 3 6668 14106 6011
