Amendment No. 7 totals$49,752 for the Phase 2 service areas(Allison,Laguna Madre and Whitecap). Based on conversations with CRG and LNV this amendment will complete the field verification efforts for the Phase 2 hydraulic model. The major tasks included in the city-wide project scope for this Amendment No.7,Phase 2—Task 12 are: • Identify areas of concern and possible inaccurate pipe diameter designations within the existing GIS shapefiles for each of the Phase 2 service areas. • Field verify pipe diameter discrepancies within the existing GIS. • Field verify manhole invert elevation discrepancies within the existing GIS • Coordinate lift station settings to identify and minimize surcharge conditions. The total amount of this Amendment is $49,752 as shown in the breakdown on Attachment "A". The man hour and fee analysis for this Amendment is shown in Attachment `B". I have also attached the project schedule for the work as shown in Attachment"C".

NO. 7 EXHIBIT "A" Page 3 of 9 Attachment A SCOPE OF WORK CITY OF CORPUS CHRISTI,TEXAS SANITARY SEWER OVERFLOW REDUCTION PROGRAM WASTEWATER HYDRAULIC MODELING Amendment No. 7 Phase 2 Task 12 CITY PROJECT E10015 BACKGROUND The approach to the hydraulic modeling of the wastewater collection system is organized around the City's objectives for this project: • Reduction in Sanitary Sewer Overflows • Cost controls and Least Cost Alternatives • Attainment of long-term Infiltration/Inflow solutions • Collection System Capacity Assurance • Regulatory compliance • Customer satisfaction GENERAL INFORMATION A hydraulic wastewater system model will equip the wastewater department with the tool for analyzing system conveyance capacities,bottlenecks,and potential overflow locations. The hydraulic model is critically dependent on the accuracy of maps and physical data associated with each pipeline. During construction of the hydraulic model some GIS data(pipe diameters,invert elevations,lift station control elevations,etc.)appeared to be in error and field verification confirmed some but not all discrepancies. To construct a viable model of the collection system required field verifications for all these discrepancies. This Amendment No.7 provides for a completion of Task 12—Phase 2 Field Verifications and model update. OBJECTIVES This amendment will address the following objectives: • Identify areas of concern and possible inaccurate pipe diameter designations within the existing GIS shapefiles for each of the Phase 2 service areas. • Field verify pipe diameter discrepancies within the existing GIS. • Field verify manhole invert elevation discrepancies within the existing GIS • Coordinate lift station settings to identify and minimize surcharge conditions. PROJECT PHASING The Phase 2 Task 12-Field Verification. MODEL BENEFITS • Accurate model construction • QA/QC on model attribute data 4 O. 7 EXHIBIT "A" Page 4 of 9 BASIC SERVICES—N/A ADDITIONAL SERVICES TASK 13—FIELD VERIFICATION 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. Task 12—Field Verification is required to verify the hydraulic model connectivity and address possible discrepancies in pipe diameters,elevations(pipe slopes),pipe and force main layout,lift station control level elevations, and other GIS discrepancies the must be field verified to confirm accuracy.
