The original contract included the development of a SSO Initiative Plan for the Oso Service Area and Amendment No. l authorized Pipeline Analysis to incorporate the Broadway and Greenwood Service Areas into the SSO Initiative program. Amendment No. 2, in anticipation of future TCEQ actions, included the Allison, Whitecap and Laguna Madre Service Areas. Amendment No. 3 provided for the development of a comprehensive city -wide hydraulic model of the wastewater collection system which included city -wide flow monitoring. Phase 1 flow monitoring of Broadway, Greenwood and Oso Service Areas was completed on schedule; however, Phase 2 flow monitoring did not record sufficient rainfall for model calibration. Amendment No. 4 to this contract is necessary due to the lack of rainfall during the Phase 2 temporary flow monitoring of the Allison, Laguna Madre and Whitecap service areas. Adequate rainfall data is critical in the process of calibrating the hydraulic model. Inadequate rainfall during flow monitoring in 2012 has necessitated the need for additional flow monitoring in May — June, 2013. The hydraulic wastewater system model will equip the wastewater department with the tools for analyzing system conveyance capacities, bottlenecks, and potential overflow locations. The hydraulic model will facilitate system analysis, aid in development of system improvements, produce informational maps /exhibits, and will predict the system's response to future improvements. The hydraulic model will enable the City to assess and predict potential capacity requirements and develop least cost strategies to optimize system performance. The major tasks included in the city -wide project scope for this Amendment No.4 are: • Wastewater Flow Monitoring at 25 key locations within the Allison, Laguna Madre and Whitecap Service Areas. • Rainfall monitoring at 12 locations to establish stone event intensity and duration.

The hydraulic model is calibrated to actual wastewater flows using temporary flow meters placed at key locations within the collection system. Inadequate rainfall during Phase 2 in 2012 has resulted in the need to obtain additional wastewater wet weather flow measurements in order to calibrate the hydraulic model. OBJECTIVES This project will address the following objectives: 1. Install approximately 25 temporary flow meters within the Allison, Laguna Madre and Whitecap service areas and record dry and wet weather wastewater flows. 2. Install 12 temporary rainfall gauges to establish the rainfall intensity and duration. 3. Analyze the recorded data and update the Phase 2 Final Report to include this additional collected data. PROJECT PHASING Phase 2 will consist of the Allison, Laguna Madre, and the Whitecap WWTP basins. The earliest historical optimum period to record wet weather flows is during May and June. MODEL BENEFITS • Flow Capacity Evaluation • Overflow Management • Infiltration/Inflow Modeling • System Deficiency Identification + CIP Development • New System Design 4 of 15 BASIC SERVICES — NIA ADDITIONAL SERVICES The development of a hydraulic model for the six wastewater service areas ensures consistent assessment of future growth, maintenance and system capital requirements for current and future conditions. Furthermore, hydraulic modeling will provide the project team consultants with pertinent data to assess system impacts to various wet weather events and will further enable the project team to test cost effective repair strategies and alternatives. Modeling will allow the team to conduct a series of "what if" scenarios that will help determine least cost solutions. These various scenarios take into account the City of Corpus Christi maintenance and personnel needs, budget, planned growth, capacity issues and can be used to more accurately design relief and/or replacement lines and optimize system rehabilitation. The following tasks are anticipated with the hydraulic modeling effort: 1.6 Wastewater Flow and Rainfall Monitoring Develop a 60 day wastewater flow monitoring plan to collect data that will be used for hydraulic model calibration, establish magnitude of wet weather inflow and prioritize sub - basins for future testing and rehabilitation. Mobilize flow monitoring team and coordinate startup. Establish personnel assignments and responsibilities. Inventory equipment needs and order expendable supplies. Perform meter pre - calibration, prepare mounting rings for various pipe sizes, set -up meter database and project information_ Delineate sub -basin boundaries based on current GIS mapping for each preliminary site such that the linear footage of pipeline within each sub -basin can be determined. 1.61 Preliminary Monitoring Locations —Previously completed 1.6.2 Finalize Flow Monitoring Locations —Previously completed L6.3 Conduct Field Inspections —Previously completed 1.6.4 Conduct Flow Monitoring for 60 days (including Rainfall Gauges) Temporary flow meters will be utilized to establish wastewater flows during dry (and wet) weather conditions. Flow metering equipment will be capable of recording flow under surcharged conditions and will be synchronized to the same clock used for rain gauges. The duration of monitoring will be 60 days_ A total of 25 temporary flow meter sites and 12 rain gauge sites are anticipated based on a preliminary evaluation. The following is a summary of consultant provided equipment: Service Area Flow Meters Rainfall Gauges ALLISON -PH2 8 4 LAGUNA -PH2 10 4 WHITECAP -PH2 7 4 Phase 2 Sub -total 25 12 Pipeline Analysis staff will use sound engineering judgment in adjusting raw depth and velocity data to account for debris, etc. and may use other analysis techniques, such as scatter graphs, AMEND. NO.4 EXHIBIT "A" Page 5 of 15 multiple flow equations and hydrographs to review data integrity or further analyze the flow data. Each meter will be field calibrated prior to installation. Calibration of each meter will consist of an independent verification of the flow depth and velocity. The flow sensors will be secured to a mounting band that fits snugly in the pipeline. The data logger for each site will then be installed and secured in the top of each manhole and the meter will be activated at industry standard user defined sampling intervals not to exceed 15 minutes. Continuously recording rainfall gauges will be installed to obtain each storm event intensity and . duration across the study area. Each rainfall gauge will be installed and calibrated to ensure proper operation and recording. Rainfall gauges are of the tipping bucket type and accurately record rainfall to 0.01 inches. Maintenance logs will be prepared by consultant for each weekly site visit and will show as a minimum the date, time, operational check, verification of recordings, and other applicable maintenance items. The frequency of site visits will be based on the site history and will generally be weekly unless more frequent visits are required due to debris of sensor fouling. Using the collection system maps in association with GIS and supplemented by the City storm water rain gauges, a rainfall distribution analysis will be performed for each major storm event. For each metered sub -area, the volume of rainfall that fell over the surface will be determined using GIS spatial analysis and compared to the discrete wet weather infiltration/inflow. 1. 6.5 Data Collection From Flow Meters Routine maintenance and service will be undertaken to confirm normal operation. Written logs of each site visit will be maintained and will be used to record date and time of visit, meter velocity and depth reading, corresponding independent velocity and depth reading, maintenance items such as battery voltage, etc. A tabular and graphical presentation of the final data will be prepared. Peak, minimum and average flow depths and rates will be generated to assist in data analysis and provided in hardcopy and electronic (MS Excel) formats. 1.6.6 Confirmation of Adequate Wet Weather Data The proposed flow monitoring will be undertaken to obtain adequate hydraulic information for dry (and wet) weather conditions. A review of the dry and wet weather data will establish the number of storm events recorded and a determination if adequate data exists or if the metering period needs to be extended. In general at least three (3) storm events, that cause a noticeable system response, will be necessary to evaluate wet weather flows. The wet weather flow data information will be used to establish rainfall derived infiltration/inflow (RDH). Both cumulative and discrete flows will be evaluated. Should rainfall not be adequate during the 60 day monitoring period then a determination will be made to either extend the flow monitoring on a week by week basis or terminate the monitoring based on forecasts for the area. The City project manager and consultant will review the data collected, review the impact on the hydraulic model, review the National Weather Service long - range precipitation forecast and make a decision on whether to extend the monitoring period. The City project manager will have the final authorization to extend the flow monitoring or terminate the flow monitoring at the end of the 60 day milestone. 1.6.7 Flow Data Analysis PA will analyze the gathered data and develop tabular and graphical summaries. Comparisons with any previous historical flow meter data from previous III Analysis, Sewer System Evaluation Surveys will be summarized and evaluated. The impact of silt and debris will be evaluated. AMEND. NO.4 EXHIBIT "A" Page 6of15 Information obtained during the monitoring period will be used to determine the following for each meter site: 1. Dry weather average daily flow A typical dry weather week will be established that is not impacted by rainfall. Velocity data will be compared to debris levels to analyze the scouring velocity necessary to prevent deposition in the lines. Discrete flows from each metered sub -basin will be calculated. 2. Dry weather peak flow — Peak flows during dry weather will be determined from the recorded meter site data. Wet weather.average daily flow — Wet weather flows for each rainfall event will be analyzed to determine the percentage of rainfall that enters the collections system (also known as the leakiness factor). By comparing the storm event flow with the dry weather flows will establish the Rainfall Derived Infiltration/Inflow (RDII). This value will vary for each storm duration and intensity. The discrete RDII for each sub -basin will be determined and will allow the ranking (prioritization) of each sub -basin by severity of RDIL 4. Wet weather peak flow — Peak flow rates during wet weather are critical to the capacity analysis. Peaking ratios (Peak flow rate to average dry weather flow) will be compared for dry and wet weather. 5. Peak inflow rates — Peak inflow rates are calculated by observing peak flow during a wet weather events. 6. Total I/I volume - The area under each storm event curve will be evaluated to establish the volume of rainfall induced infiltration/inflow. These values can then be normalized to establish the volume of RDII per inch of rainfall. Projections can then be made to accurately determine the impact of RDII during a normal year. During data analysis, the Manning and continuity equations may be plotted for flow. Under ideal free flow hydraulic conditions the two separate equations for flow should provide similar results. However, in a backwater or restrictive hydraulic situation, the Manning equation will over quantify flows and diverge from the continuity equation. Such an occurrence will indicate to the data analyst that a backwater condition was observed and a downstream restriction should be investigated. The project team will use sound engineering judgment and experience in adjusting raw depth and velocity data to account for debris levels. By obtaining accurate velocity and depth data, the engineer can further isolate hydraulic problems within the collection system. 1.6.8 Ranking of Meter Sub - basins A major result of the city -wide flow monitoring program will be the priority ranking of sub - basins based on various factors such as RDII, SSOs, maintenance history, etc. This matrix ranking will be used in a multi -year program to find and fix system defects. Using the rainfall distribution analysis and recorded wet weather flow data, the gallons of rainfall dependent I./I (RDII), per inch of rainfall, per linear feet of service area pipeline (gal/in/If) will be calculated. By performing this matrix analysis, each sub -basin is compared, assessed and ranked on an equal basis. Consultant will prepare a matrix for city review and approval. 1. 6.9 Preparation of SSES Phasing & Cost Estimates Based on the matrix ranking of sub - basins, a phased Sanitary Sewer Evaluation Survey (SSES) AMEND. NO.4 EXHIBIT "A" Page 7 of 15 program will be prepared along with estimated implementation cost estimates. 9.6.10 Review of Uf Study Report PA will prepare three (3) copies of the 111 Analysis Pre - Submittal Final Report which summarizes all findings, observed deficiencies, and recommendations with estimated costs.
