This project involves the Installation of a wastewater duplex lift station, approximately 1,470 linear feet of 18" gravity sanitary sewer and approximately 10,185,1wlinear feet of 18" diameter sanitary sewer force main (See Exhibit 'C' - Project Overview). YIew). The London Area Wastewater Plan was adopted by City Council In April 2017 and provides a wastewater service area for an area south of Oso Creek (see Exhibit 'A'). This system will initially serve a proposed development to the west along County Road 33. Uitlmately it will serve all of the area within the London Area Wastewater Master Plan. The London Area Wastewater Master Plan, as adopted, calls for two 15-Inch gravity sewer lines to deliver the flow from the entire service area to a common manhole, and then to the proposed lift station via a single gravity sewer line.As the lift station Is proposed to be located approximately in the center of the service area, it is assumed that each of the 15-inch gravity lines would carry approximately half of the total flow. Based on the criteria adopted by the city with the master plan, a 15-inch gravity line does not have sufficient capacity to carry half of the total flow from the service area. Based on that same criteria, an 18-inch gravity line does have { sufficient capacity to carry half of the total flow from the service area. An 18-inch gravity sewer line will provide a 40% greater capacity than the 15-Inch line, and will do so at no additional cost to the city. See the Capacity Calculations Exhibit included with Appendix'D'. The proposed project includes 18' diameter gravity sanitary sewer lines to be built at master plan depths to serve the entire London Area Service Area. The proposed gravity sanitary WNW will start at the new lift station and branch out to serve the proposed development to the west of the lift station. A stub-out will be provided from the lift station to the east for future extension to serve developments on the east side of the London Wastewater Service Area. The proposed gravity sanitary is planned to be constructed along city and private property. Utility easements will be dedicated for all wastewater infrastructure as needed. The material for the gravity sanitary sewer will be PVC(Green, SDR-21). The proposed wastewater lift station is a duplex submersible pump station with an 8'diameter x 30' deep fiberglass wet well. Lift station is designed such that both the Phase 1 and future Phase 2 pumps will function with no changes, other than replacing pumps and control panel. The proposed Phase 1 pumps are 12 horsepower submersible pumps. Future development in this area will dictate when the future Phase 2, 20 horsepower submersible pumps wiN need to be installed in the lift station. Design of the proposed lift station will follow criteria established by ICED in TAC 30 Chapter 217 and will conform to the City of Corpus Christi standards. f London Area Wastewater Plan Lift Station No 1 LW ENGINEERING Page ES-1 of 2 EXECUTIVE SUMMARY The proposed lift station will pump into a proposed 18' diameter force main that will be constructed across City property, within the Greenwood Drive right-of-way, and within the Saratoga Boulevard right-of-way, and will discharge into the plant lift station at the Greenwood Wastewater Treatment Plant. Utility easements will be dedicated where needed. Design of the force main will follow criteria established by TCEQ in TAC 30 Chapter 217. A portion of the force main will be installed by directional drill across Oso Creek. The material for the drilled portion of the force main will be Fusible PVC(Green, 0.900, DR 18, pressure class 235 psi). The Material for the remainder of the force main line will be PVC (Green, C-900, DR 18, pressure class 235 psi). Pipe embedment and trench backfill will conform to applicable City of Corpus Christi standards. l London Area Wastewater Ptan Lift Station No l INGINSIERINC3 Page ES-2 of 2 SECTION I - INTRODUCTION A. Ming The objective of this report is to Identify, analyze and review design issues relating to this project, develop a work plan and provide recommendations for the new wastewater lift station per the London Area Wastewater Plan. The proposed new sanitary sewer infrastructure includes a gravity sewer system, a lift station, and a force main. To date there has not been any public wastewater systems to serve this area. This system will initially serve a proposed development to the west along County Road 33. Ultimately it will serve all of the area within the London Area Wastewater Master Plan. B. ).ONQON AREA WASTEWATER PLAN ADOPTED APRIL 2017 The London Area Wastewater Plan was adopted by City Council in April 2017 and provides a wastewater service area for an area south of Oso Creek. The service area is bounded by Oso Creek on the north, SH 288 on the east,Weber Road on the south, and farmland to the west. See Exhibit A at the back of this report for a map of the Wastewater Plan. Grades for the service area generally drain from south to north (Weber Road to Oso Creek). The Wastewater Plan indicates a lift station to be located on City property near Oso Creek to take advantage of the natural ground slope and �. help with extending gravity collection system to the service area boundaries. However, the master plan shows gravity sewer coming from the east and west, combining approximately 1,100 feet south of the lift station, and then flowing by gravity sewer north to the lift station. This effectively eliminates any advantage gained by moving the lift station to the lower elevation. Therefore, It is proposed that the lift station be located approximately 1,100 feet south of the location depicted on the master plan. This will eliminate 1,100 feet of gravity sewer end replace with force main which is considerably more economical. The force main will be constructed from the new rift station northward through city property, and then adjacent to Greenwood Drive terminating at the lift station at the Greenwood Wastewater Treatment Plant. The Wastewater Plan indicates the force main to be 16'diameter. Branching out from the new lift station to the east and to the west will be gravity sewer lines. as indicated on Exhibit A. The line to the east will be a short stub-out which will be capped for future extension. The line to the west will be installed approximately to west edge of the County Road 33 right-of-way. li London Area Wastewater Plan Lift Station No 1 erf a Page 1 of 10 SECTION I - INTRODUCTION C. SITE DEDICATION The Nft station site will be located on city property.The gravity collection system will be located on city and private property. The force main will be located on city property, and within dedicated right-of-way. Utility easements will be dedicated for ell wastewater infrastructure as needed. Metes and Bounds descriptions with exhibits will be provided for these locations where necessary. London Area Wastewater Plan ° ~ LdtPt 10 SECTION II -- UFT STATION DESIGN CRITERIA A. SITE SELECTION The new London Area Lift Station No. 1 will be located on the City's property south of the Oso Creek and will be designed such that It can serve the entire*Melte arse by gravity(See Exhibit A for approved wastewater plan). Metes and Bounds with exhibit will be developed for the site that the NR station will encompass. The sats will be large enough to construct the Phase 1 lift station wet well and allow construction of future wet well to expand the pumping capacity. B. DESIGN FLOW The design !low for the proposed Itt station was calculated by deteminitg the land use for the various parcels of land within the aft station service area per the City's London Area Wastewater Plan (see Exhibit A), applying the master plan flow rate per land use type and then totaling the flows. A peaking factor of three was used, based on the Babbitt formula, and 400 gallons/dayyhcre was added for infiltration. Potential ftowrate from the London Independent School District (ISO) property was also added. based on information provided by the school district. Exhibit 8 shows more detailed information of the service area and land use savage used to develop the design flows. Flow calculations are shown in the table on the following page and recommended design flows for this lift station are as follows: Phase 1 Design Flow: 825 GPM(0.90 MGD) Future Phase 2 Design Flow: 1,220 GPM(1.78 MGD) Future(Ultimate)Design Flow: 3,044 GPM(4.38 MGD) The components of the lift station, except for the pumps and control panel, will be sized to handle the Phase 2 design flow of 1.78 MGD(1,220 GPM). The lift station will be designed using Flygt(Xylem)submersible centrifugal pumps.

WET WELL.DESIGN 1. WET WELL,VOLUME The lift station will be designed using the criteria set forth in TCEQ's Chapter 217 of TAC 30. The primary design consideration for lift stations is given to wet well volume. The wet well volume required is calculated using the formula found in TCEQ Ch 217.60. V=(T•Q)1(4.7.48) V=Active volume(cubic feet) Q=Pump capacity(gallons per minute) T=Cycle time(minutes) This formula is used to calculate wet well volumes when the pump capacity is equal to the peak flow. For less than 50 Hp motors a pump cycle time of 6 minutes Is required, for 50 to 100 Hp motors a pump cycle time of 10 minutes is required and for greater than 100 Hp motors a pump cycle time of 15 minutes Is required. For future peak flow of 3,044 GPM (4.38 MGD) additional wet well capacity will have to be constructed.A stub-out for an interconnecting pipe between the existing `., and future wet wells is being provided. The preliminary recommended dimensions for a fiberglass round wet well are: Diameter 8'-0" Water Depth: 5'-0" (El. 3.00 to El. (-)2.00) Area: 50.3 SF Total Volume: 251 CF (1,877 Gallons) 2. PUMP LEVELS Recommended pump levels based on design flow are provided in the following. High Level Alarm On El. 3.00 Lag Pump On El. 1.80 Lead Pump On El. 0.60 Pumps Off El. (-)2.00 Actual levels will Nicely vary during initial flows and flow changes will occur over time. Flow should be monitored and changes made in the field as necessary.

D. RUMP HEAD CALCULATIONS Pump design is based on the system analysis as presented in Appendix 'A' for one pump running (second pump is backup pump) and with the new 16" dia. force main. The system curve was developed utilizing hydraulic calculations. E. UFT STATION EMERGENCY PROVISIONS 1. STORAGE CAPACITY According to TAC 30 Chapter 217, storage capacity must be provided for 20 minutes of peak flow In the event of a power outage(or equal to the longest power outage in the last 60 months), to prevent the release of untreated wastewater. Nueces Electric Cooperative (NEC) provides power for the lift station site. Since this is a new lift station and a new overhead power supply will have to be constructed, there is no historical information for outages to this lift station. However, NEC has provided power outage information for the London ISO area London Area Wastewater Plan Lift Station No 1 ENGINEERING Page 6 of 10 SECTION II - UFT STATION DESIGN CRITERIA (see Appendix 'C'). The information provided indicates the longest duration of power outage to the area was over 26-hours during Hurricane Harvey. This duration would result in a storage amount which cannot be contained within the wet well, gravity fines, and manholes. Therefore, a diesel powered back-up generator will be permanently located on site and provided with an automatic transfer switch. The generator will be sized to run one of the two phase 2 lift station pumps for at least 27 hours (one pump is designed to pump the phase 2 peak lbw). Generator will be self-starting with the loss of the primary power source. 2. DISCHARGE PREVENTION SYSTEM An audiovisual alarm system consisting of a Supervisory Control and Data Acquisition (SCADA) panel located at the lift station will be provided to communicate station conditions and alarms to the Wastewater Service Center. The alarm system will monitor and provide notification of power outages, pump failures and/or a wet well high water level. F. UTILITIES IN PROJECT AREA There are no known utilities located in or around the proposed lift station site. There is an existing Enterprise gas pipeline which traverses the city landfill property and runs along Greenwood Drive. The proposed force main will cross the existing gas pipeline just south of the Greenwood Drive terminus at the city landfill property. The proposed force main will be located on the east side of the Greenwood Drive pavement and will run parallel to the above mentioned existing gas pipeline, an existing city gas line, and a small diameter sewer force main. G. GEOTECHNICAL INVE,$TIGATION Geotechnical investigation of the subsurface materials and conditions was performed at the lift station site, along the route of the force main and along the route of the gravity lines and a study prepared by Rock Engineering & Testing Laboratory, Inc. A copy of the boring log and the results of the soil sample analysis are provided as Appendix 'B'. The soils at the lift station are described as firm to stiff, highly plastic, dark grey to brown day. Ground water was encountered at four of the six bore holes during the drilling operation and read again 24 hours later and water levels are presented in the soils report pages in Appendix 'B'. Well pointing of some sort will likely be required for some of the construction elements. i London Area Wastewater Plan IIURBAN Lift Station No 1 ENGINEERING Page 7 of 10 I SECTION II - UFT STATION DESIGN CRITERIA The entire geotechnical study will be included with the bidding documents for use by the contractors bidding the project. London Area Wastewater Plan ��� Litt Station No. 1 ENo1�NEER,INe Page 8 of 10 SECTION III - PROPOSED IMPROVEMENTS A. UFT STATION 1. Pumps and Accessories The proposed lift station is a duplex lift station, two pumps will be installed, with one pump handling the design flow and the other pump acting as a backup pump. The lift station will initially have 12 Hp Phase 1 pumps. When flows increase and the Phase 1 pumps new capacity future Phase 2 20 Hp pumps can be installed and control panel replaced. 2. Wet Well:. The proposed wet well will be 8' In diameter, approximately 30' deep, and made of fiberglass. Active volume with 5'-0" operating level is 251.5 CF (1,881 Gallons). The fiberglass wet well would be constructed with concrete bottom and top slab (note that there is also a fiberglass top to the vessel to protect the top from hydrogen sulfide gasses). One access hatch, wide enough to serve both phase 1 and phase 2 submersible pumps, will be provided in the top of the concrete roof to allow access to the pumps. Access hatches will be provided with safety grating for fall protection when the access door is opened. 3. Lift Station Discharge Piping and Valves(above ground) For ease of maintenance, the proposed lift station isolation and check valves will be installed on top of the station above the top slab. All above ground discharge piping will be constructed with ductile iron pipe and fittings. An emergency bypass connection will be provided on the downstream discharge header with a tee, plug valve and blind flange to allow connection of a temporary pump should the need ever arise to bypass the lift station wet well or due to pump failures. 4. Wet Well Ventilation The proposed lift station will have passive ventilation per TCEQ Chapter 217 Regulations. The passive ventilation will consist of one 8"pipe vent with a stainless steel bird screen over the end. 1.76 MGD=2.72 CFS x 60 Min/Sec= 163 CFM Each Area Required: 163 CFM/500 FPM= 0.33 SF Min. USE ONE 8'DIA. VENT(0.349 SF) 5. Flow Meter The proposed lift station will include a flow meter to measure flow through the discharge piping. The flow meter will be installed in a fiberglass manhole adjacent to the Eft station wet well downstream of the above ground discharge piping. London Area Wastewater Pian Uh Station No 1 ENGINEERING Page 9 of 10 SECTION III - PROPOSED IMPROVEMENTS 6. Odor Control Since the proposed lift station Is brand new and peak flows are minimal, there will be no odor control systems installed at the lift station site. Space is being provided on the site, though, for a future talo-fuer type odor control unit, should the need arise. 7. Miscellaneous Site Improvements • The lift station will be accessible from County Road 33 with construction of a new 12'wide access road from the existing country road to the Oft station site. Proposed access road is outside of the boundary of the existing and proposed FEMA 100 year storm event. • For security, the proposed lift station site will have a 8'tail chain link fence with three strands of barbed wire. Access to the new lift station will be through a lockable 3' wide personnel gate and a lockable 12' wide main gate to allow for vehicular entry. • Control panels and wet well access hatches will also be lockable to limit access. • A security light will be provided with dusk till dawn photo cell. B. FORCE MAIN 1. Force Main Piping The proposed 16" diameter sanitary sewer force main will be constructed of PVC (green, C-900, DR 25, pressure Gass 165 psi). The proposed force main will be installed with a minimum of 2'-13"of ground cover. 2. Line Valves Line valves for isolation of the force main will be installed at maximum 2,000' i intervals. C. GRAVITY SANITARY SEWER 1. 18" Diameter PVC All proposed PVC gravity lines will be installed at master plan depths. 2. Manholes Manholes for this project will be spaced at a maximum of 500' apart per TCEQ Chapter 217 requirements. Manhole wall thickness and construction will conform to City of Corpus Standard Details and Specifications.

It should be noted that the values for the design of braced excavations provided in the tables above are based on the soil strengths and soil densities encountered in the field and generally accepted empirical formulas correlating undrained shear strengths to drained shear strengths and the corresponding angle of internal friction for clay soils. The active and passive earth pressure coefficients were calculated using the drained angle of internal friction as recommended in "FOUNDATION ANALYSIS AND DESIGN",written by Mr. Joseph Bowles where he states, "Drained soil parameters for stiff clays and s-C soils in general may be appropriate for lateral pressures behind braced walls where the excavation is open for a considerable length of time."

Michael the following are the comments on the information in the design memorandum that was submitted November 3r0. • Section II Flow calculations are based on approximately 4 homes per acre per the city's master plan the preliminary subdivision plan shows a density quite a bit higher than that closer to 6 units per acre. This subdivision will set the tone for the area development, is the design for 4 units per acre realistic? The preliminary layouts for the proposed subdivision result in a density that is dose to that assumed on the master plan.The proposed subdivision will be located on a tract of approximately 120 acres.The master plan projected that the service area would include approximately 750 acres of residential development.It is assumed that the average density for the overall 750 acres of residential development will be in line with the assumptions on the master plan.Therefore,the design is based on the criteria set forth in the master plan. • Section II emergency storage is based on the outages in the area for the last 60 months not necessarily at the lift station. Please provide the outage history for IAPPENDIX D' that area for the last 60 months you may use the London school complex. Identify how much of this was from the hurricane. Outage history has been provided by Nueces Electric Cooperative(NEC)for the London iSO area.Based on the information provided,It was determined that adequate storage could not be provided.Therefore,the design has been revised to show a back-up generator for phase 1. • Storage capacity, The majority of the storage volume shown on page 7/10 48,762 gal. is in the line to the east serving the sports complex. As this is not scheduled to be constructed it is not realistic to use it for the majority of the storage unless there are plans to construct this line in the near future. Update the storage capacity calculations based on what is currently proposed for construction. See response to above comment Storage capacity is no longer relevant as design now includes a back-up generator to be installed with phase 1. • The master plan calls for a 15" gravity line please provide capacity calculations to justify the increase to 18". Increasing this to 18" will require a master plan amendment. In order to facilitate the masterplan amendment the utility department needs to agree and approve the capacity calculations for the upsizing of the line. Based on criteria set forth In the master plan,the peak design flow for the service area to the lift station will be 3,044 GPM.The lift station is located approximately in the center of the service area.Assuming the two proposed gravity collection lines will split the flow evenly,each line will carry 1,522 GPM.The capacity for a 15- inch gravity collection line laid at minimum allowable slopes is 1,160 GPM.This is less than the anticipated peak flow.The capacity for an 18-inch gravity collection line laid at minimum allowable slopes is 1,633 GPM. Therefore,it is necessary to use an 18-inch line in lieu of a 15-inch.(see attached capacity calculation exhibit) • • How will AEP be serving the lift station? Will there be easement requirements and will there be costs associated with the extension of service to the site? The lift station will be served by Nueces Electric Cooperative(NEC),not AEP.Our team coordinated with NEC regarding electric service to the proposed lift station.Electric service will be routed from Weber,North along County Road 33,and then East within the proposed Access and Utility Easement from County Road 33 to the lift station site. Michael these are the comments that we have received from the Utility department and an internal review. Please address these comments so I can respond to Utilities.

Criteria for values used in the above calculations was obtained from the Adopted London Area Wastewater Master Plan(see Exhibit'A'of this Memorandun),and from the Adopted Allison Service Area Wastewater Master plan(see remainder of Appendix'D'. 2. In accordance with common practice for this area,it Is assumed the proposed gravity wastewater lines will be installed at the minimum allowable slopes. 3. Lift station is proposed approximately in center of service area.Therefore,it is assumed each of the two proposed gravity collection lines will carry approximately half of the total peak flow. APPENDIX 'D'J • Wastewater Collection System Design 20 feet Selection of locations for lift stations and force mains were dictated by topography while avoiding parallel gravity lines and force mains wherever possible. 3.3 Summary of Sanitary Sewer Collection System Design The sanitary sewers included in this master plan were designed on the basis of information contained in the proceeding paragraphs of this section. A brief description of this information and assumptions, which were used as a basis for the design,are outlined below: I. Ground elevations were obtained from Lidar-produced topographic maps furnished by the City of Corpus Christi. 2. Area served by a sewer assumed to be fully developed. 3. Peak domestic flow=M x Average Domestic Flow where M =5/P115;where P=population in thousands of contributing sub-basin. 4. Infiltration=400 gal/acre/day. 5. Design Flow=Peak Domestic Flow +Infiltration. 6. Upper end of small lateral to have a minimum depth of 5 feet. 7. Minimum size of pipe for trunk mains = 10 inches. 8. Minimum design velocity=2 ft/s. 9. ( ijiity'o£pipeii ti on' tanning ftimiuln: 1Ai/n3t`�tfz� '. 10.

Appendix A illustrates the Quantity of Wastewater Flow for each land use based on area and population. Using the charts in Appendix A, Appendix B was developed to illustrate the anticipated wastewater flows in each wastewater basin,and furthermore, in each sub-basin. 3.4 Lift Station Analysis Lift Station analysis was performed by anticipating all upstream wastewater contributions and comparing this result with the existing capacity for each station. Proposed lift stations in the system should be designed to handle the anticipated wastewater flows. There are thirteen existing lift stations and seven proposed lift stations in the Allison Service Area. Each lift station is tabulated in Appendix C. [APPENDIX'D'.
