Exhibit A WORK PLAN This section is a detailed description of the Work Plan that would be implemented for this project. Specific work items were developed based on our understanding of the project needs, our familiarity with the City of Fayetteville's wastewater collection system, and our experience with many other similar projects. The current sewer system in the Illinois River Watershed is estimated to contain approximately 137 miles or 725,000 LF of sewer and 3,500 manholes. The sewer system study of the Illinois River Watershed will consist of two Phases. Phase I activities will include flow monitoring of the entire wastewater collection system in the Illinois River Watershed and intensive survey activities in Mini Systems 4, 8, 11, 12, and 16, which is further defined as the Study Area. The Phase I study area is estimated to contain 381,000 linear feet of sewer and 1,820 manholes. Phase II activities will include intensive survey activities in Mini Systems 1, 3, 7,17, and 22 and will not be initiated without authorization from the City. The Phase I and Phase II activities are further described in the following sections. Phase I Work Plan Major phases of the work program for Phase I are listed below with work item details shown on the following pages. Item I Project Initialization, Administration, and Management Item II Physical Survey and Flow Monitoring Item III Rainfall Simulation Item IV Interim Report/Cleaning and Internal Television Inspection Item V Analysis and Report The Phase I Work Plan for the City of Fayetteville includes all the necessary engineering, planning, and survey work for developing an Overflow Elimination Plan in Mini Systems 4, 8, 11, 12, and 16 of the Illinois Drainage Basin. • I.

Notify City contact of all discrepancies found within these plans based on field observations and limited to general location of manholes, direction of flow, general depth of sewers, and any missing sewers or buried manholes. 4 Meet, initially, with the City staff to give briefing on the investigation strategy and to introduce key personnel. B. Project Administration 1. Meet with City staff on a periodic basis to update previous investigative work, to coordinate upcoming work, and to receive any input from staff. Provide a written report on the progress at these meetings and distribute to designated representatives. They will be held periodically at significant project milestones with written documentation of each meeting provided. 2. Prepare final schedule of work activities. 3. Perform general consultation with representative City staff on an as -needed basis. Provide general overview opportunities for City personnel for observing regularly scheduled field inspection and testing activities. 4. Perform administration and coordination of television inspection subcontractor including, but not limited to, contract finalization, performance coordination, and payment request verification. 5.

During all phases of this investigation, the Engineer will notify the City of all major I/I defect sources that, if corrected in an expedient manner, will result in a significant reduction of I/I flows. Such I/I sources include, but are not limited to, storm sewer overflows and cross -connections. C. Public Relations 1. Engineer will prepare and deliver all notices or signs necessary for the public relations program as well as providing media announcements/relations techniques (e.g. smoke testing) and private sector contributions (e.g. dye water testing) in connection with City staff. 2. The City will designate the contact point for receiving, handling, and disposition of area resident inquiries during this project. D. Data Management Program 1. Perform final review of system maps to delineate preliminary boundaries of subdrainage areas and locations of additional flow monitoring sites. It is assumed that the City will provide maps of the designated system. 2. Perform field checks for final location and type of flow meters and ram gauges necessary to supplement city -owned permanent meters. 3 Establish manhole numbering system of each subdrainage area in accordance with the RJN CASS methodology. Update system as field activities are performed. 4 Prepare preliminary field map for project use. Existing sewer maps will be obtained from City records. Al]. drainage areas, sewers, and manhole numbering will be shown on the map. 5. Obtain preliminary sewer segment distances, sewer diameters, sewer slopes, available invert elevations for City sewers from existing City sewer as-builts. City will be notified of any missing elevation data or questionable data. 6. Determine estimated average base flows for each drainage area from water records to be provided by the City. 7.

Install, calibrate, service, and maintain temporary meters, as necessary to supplement the City's permanent meter stations for a period of 60 days. It is assumed that adequate weather conditions will be observed during the monitoring period so that dry and wet weather conditions, and at least three storm events of different rainfall intensities are monitored which do not result in surcharge conditions. Continuous recording meters with depth/velocity capability will be used on the gravity mains and collector sewer locations so that surcharge flows, if any, can be monitored. It is anticipated the wet weather monitoring and dry weather monitoring will be conducted consecutively to avoid reinstallation of equipment. A total of 8 flow meters are estimated to be required to supplement the City owned flow meters. 2. Install and service three rain gauges with 0.01 inch accuracy in the study area to obtain a continuous record of rainfall conditions during the flow monitoring 1 period. Rain gauges to be synchronized to the same flow monitoring clobk. 3. Evaluate and make recommendations to City for procurement of rain gauges for City's continuous use. Evaluate and make recommendations for placement of permanent raingauges. 4. Remove flow meters and rain gauges. Obtain final manual depth and velocity readings to compare to metered data. 5. Analyze flow data and develop base flow diurnal curves and base flow peaking factors. Correlate with water consumption records, if possible. 6. Analyze flow data and develop estimated peak groundwater infiltration rates if possible. 7. Analyze and tabulate rainfall data at three rain gauge sites. 8. Determine peak inflow rate for selected rainfall events and determine corresponding rainfall intensity for areas tributary to all flow monitoring locations. 9. Establish the relationship between peak inflow and rainfall (Q vs i) for each area tributary to a monitoring location. B. Analysis of Data From City Owned Flow Meters Flow data to be supplied by the City will be analyzed to determine dry and wet weather flow conditions for each permanent monitoring location. It is assumed that depth of flow, flow velocity, and flow rate data will be supplied by the City for each metering location. Flow data will be analyzed to determine where possible the following: 6 .1••• 6 a. Average base flow under dry weather and low ground water conditions, and Peak flow VaiiiS for each monitoring location. b. Determine infiltration rates under high ground water conditions if possible. c. Determine peak inflow rates under high groundwater conditions and develop relationship between peak inflow and rainfall intensity for area tributary to a flow meter. C.

For the purpose of the cost estimate it is assumed that 1,820 manholes in the Phase I Study Area will require inspection. 1. Perform comprehensive internal manhole and visual pipe inspection for manholes in the study area. Any manholes exposed or made accessible by the City within 60 days following notification by the Engineer will be inspected. A total of 1,820 manholes are estimated. 2. Input below ground/visual pipe inspection data to project computer files, assign flow rates, obtain output reports for I/I sources, I/I flows, and I/I rehabilitation costs. III.

Perform dyed water flooding on selective storm sewer sections; suspected overflows, stream and ditch sections, and other ponding areas in the public sector that may be contributing to inflow. It is estimated that 60 locations in the public sector will be dyed water flooded. 3. Perform dyed water flooding in private sector (drains, downspouts, etc.) with prior notification of the resident. It is estimated that 28 locations in the private sector will be dyed water flooded. 4. Input dyed water data to computer to obtain reports for cross connections and estimated flows. • IV.
