(FNI) a comprehensive wastewater master plan update for the Collection System addressing population growth, regulatory compliance, aging infrastructure, and develop a Capital Improvement Plan. The original contract was executed on May 11, 2017. Original Scope elements include: • Task A: Population/wastewater flow projections and short-term analysis • Task B: City-wide temporary flow monitoring program • Task C: All -pipes wastewater collection system model development • Task D: EPA Capacity Management Operations and Maintenance program development Amendment #1 Scope elements include: • Task E: Hydraulic model calibration and design storm • Task F: Wastewater System Performance Analysis • Task G: Collection system Risk Based Assessment • Task H: Wastewater collection system capital improvements plan (CIP) and Report • Task I: Wastewater model training The Amendment #1 items are detailed in the following pages. WASTEWATER COLLECTION SYSTEM ANALYSIS: AMENDMENT #1 ITEMS TASK E: EXTENDED PERIOD SIMULATION (EPS) WASTEWATER MODEL CALIBRATION E1. DRY WEATHER CALIBRATION FNI will select a dry weather calibration event to isolate projected flows as primarily domestic contributed flows. FNI will develop a flow meter schematic showing which sewer basin and metered sub -basins feed into each sewer interceptor for model analysis and data output review. FNI will perform dry weather calibration of the selected dry weather flow event using calibrated flow volume by adjusting antecedent conditions, per capita flows, diurnal curves and dry weather infiltration. FNI shall prepare charts and profiles at selected calibration points showing metered vs. modeled dry weather calibration for flow, depth and velocity. E2. WET WEATHER CALIBRATION FNI will review the flow meter data and select a wet weather calibration storm event. FNI will perform wet weather calibration using the EPA approved RTK methodology on selected wet weather flow events using calibrated peak 1/I. FNI will adjust model parameters to calibrate flow, velocity and flow depth. FNI Wastewater Master Plan — Exhibit A FREESE c��> °� Contract No. 13135 900111 ZN�CNOLS Lubbock Amendment #1 Scope of Work I, IJIJ TEXAS will prepare charts and profiles at selected calibration points showing metered vs. modeled wet weather calibration results. E3. DESIGN STORM EVALUATION FNI will evaluate design storms and develop recommendations on design storms using return period and storm intensity for individual sewer basins and interceptors and systemwide storms for the wastewater treatment plant facilities, based on level of service recommendations using existing available data. E4. FLOW MONITORING, MODEL DEVELOPMENT, CALIBRATION AND DESIGN STORM SELECTION WORKSHOP (WORKSHOP #3) FNI will conduct a workshop with the City to discuss the flow monitoring, model development, model calibration, and design storm evaluation. E5. PREPARE MODEL DEVELOPMENT AND CALIBRATION CHAPTER FOR MASTER PLAN REPORT FNI will prepare the Model Development and Calibration chapter of the Wastewater Master Plan and submit five (5) hard copies and a PDF to the City for review. TASK F: WASTEWATER SYSTEM PERFORMANCE ANALYSIS Fl. DESIGN CRITERIA AND LEVEL OF SERVICE EVALUATION FNI will evaluate and recommend wastewater system planning criteria, including design flows, minimum and maximum pipeline velocities, TCEQ requirements and surcharging guidelines. The criteria will determine the level of service and what surcharging, if any, is allowed, minimum and maximum velocity constraints, etc. Criteria will be developed for overall master planning purposes, development reviews, and environmentally sensitive areas. F2. EXISTING SYSTEM EVALUATION FNI will run the calibrated wastewater model with design storm(s) and identify existing surcharging and overflow locations and other capacity/restriction issues. This will provide the baseline evaluation of where the collection system currently has issues. This task will establish critical projects that will be included in the 5-year CIP planning. FNI will conduct an evaluation to determine the impacts of critical element (special structure) and lift station modifications on the existing system evaluation results. FNI will prepare mapping and model results showing all surcharging and overflow locations by magnitude and locations. FNI will categorize manholes by overflow amounts during design storm and sewer line surcharging by amounts during design event(s). F3. LIFT STATION SITE VISITS FNI will conduct site visits at up to 8 lift stations to update the condition evaluation and determine rehab or replacement needs. At the site visit, FNI will evaluate electrical, structural, SCADA, pumps and motors. FNI will assign an updated condition score for each lift station. F4. MEETING ON EXISTING SYSTEM ANALYSIS AND DESIGN CRITERIA FNI will meet with the City to present the existing system analysis results and design criteria.

FUTURE SYSTEM ANALYSIS FNI will finalize model scenario development for 5-year, 10-year, and 20-year conditions and run wastewater model scenarios under design storm conditions to determine the system response for surcharging and overflow events. FNI will utilize the future system model scenarios to analyze the impact of future growth and development on the wastewater collection system. FNI will apply the selected design storm(s) to the future system models to locate potential future system deficiencies based on specified design criteria. FNI will conduct an evaluation of special structures and lift stations under design storm conditions for each planning period. F6. EVALUATION OF LIFT STATION CONSOLIDATION AND ELIMINATION OPTIONS FNI will utilize the existing and future system modeling results, along with the information from the lift station site visits to evaluate alternatives to eliminate or consolidate lift stations to the extent possible. FNI will evaluate phasing of improvements to facilitate lift station consolidation/elimination. F7. LIFT STATIONS SYSTEM RELIABILITY EVALUATION FNI will utilize data from the model and lift station as-builts to evaluate the impact of a power outage, including available wet well storage, flow and capacity in the upstream lines and backup power availability. FNI will identify which lift stations should be brought back into service first and where emergency generators are needed to facilitate a greater response time. F8. WRP CAPACITY EVALUATION AND NW WRP INTEGRATION FNI will identify, evaluate and provide recommendations regarding the ability to meet the existing and projected wastewater collection and treatment needs of the service area. FNI will evaluate the integration of the new Northwest WRP to the collection system. FNI will evaluate options for flexible flow management allowing the collection system to redirect or transfer flow based on operational decisions. FNI will provide charts and graphs with alternatives to meeting future wastewater treatment plant flow projections. F9. DEVELOPMENT OF WASTEWATER SYSTEM IMPROVEMENT ALTERNATIVES TO ADDRESS CAPACITY ISSUES AND PROVIDE FOR FUTURE GROWTH Using the results of future models, FNI will develop improvements to eliminate excessive surcharging and overflows in the collection system resulting from increased wastewater flow from projected future growth, development, and redevelopment. FNI will develop improvements alternatives for gravity lines, lift stations, force mains, special structures, and treatment facilities. Improvements needed to correct existing deficiencies will also be included. FNI will utilize model results to develop improvements to serve areas that are currently not developed. FNI will prioritize rehabilitation areas based on flow monitoring results and operational data to help reduce infiltration/inflow. FNI will develop mapping showing improvements required for the 5-year, 10-year, and 20-year planning periods as well as improvements needed to correct existing deficiencies. F10. WASTEWATER SYSTEM HYDRAULIC ANALYSIS AND IMPROVEMENT ALTERNATIVES WORKSHOP (WORKSHOP #4) FNI will develop an alternative solution workshop with City Staff to assess and evaluate future hydraulic/operational improvements to solve deficiencies based on costs, benefits, and ability for projects to be permitted.

ASSIGN CONDITION AND CRITICALITY SCORES TO WASTEWATER PIPE SEGMENTS FNI will evaluate the condition and criticality of each wastewater pipeline segment based on the parameters developed in previous task. Condition and criticality scores will be assigned to each pipeline segment. Pipeline segments are defined as the span between manholes. G5. DEVELOP OVERALL PRIORITIZED RISK SCORES FOR EACH PIPE SEGMENT FNI will review the results of the previous task and develop the groupings for the condition and criticality scores into categories (such as "good", "poor", etc. condition and "high", "low", medium" impact) and develop risk scores for each pipeline segment. G6.
