EXHIBIT A City of Prescott 2012 Water Distribution System Model Update SCOPE OF WORK Task 2.0 Deliverable: A draft of the report section that presents results of the water system evaluations will be prepared following the workshop that addresses water system evaluations. Recommendations that result from the investigations in this task will consist of infrastructure and operating recommendations. The City will provide comments on the water system evaluations that will be incorporated into the draft report. A map of fire flow results will also be provided as a deliverable. TASK 3.0 WATER SYSTEM PLAN UPDATE 3.1 Capital Improvement Program Capital improvement projects will be identified and sized to address water system improvements that are identified from the water system evaluations in Task 2.0. Planning level cost estimates, time period, trigger, and impact fee zone will be developed for each project. Projects will also be classified according to their purpose: to serve new growth or to resolve a current deficiency. Where projects may serve new growth and address deficiencies, the percentage allocation and percentage of the cost will be established. Costs will be based on the assumption that pipes with insufficient capacity will be replaced with a larger pipe and not be paralleled with an additional pipe to provide the required capacity. Capital improvement project definitions will be organized in a format prescribed by the City to fit into the City's CIP program. These project definitions will include a justification and purpose, location map, cost, and construction time period and trigger that would indicate the need to start the project. CIP projects will also be organized in a spreadsheet format that the City can use after the project is completed to shift the timing of projects in the future as growth and other conditions change in ways that are not anticipated at the time that this project is being completed. The CIP will be based on a 20 year buildout with five year interim planning periods. 3.2 Impact Fee Service Areas The City will be divided into impact fee zones that can be used to identify the specific infrastructure needed to serve each impact fee zone so that the costs of constructing new infrastructure can be allocated to the customers that will benefit from this infrastructure. Capital improvements will then be associated with the zone or zones that benefit from these improvements. Capital improvement projects will then be organized according to impact fee zones. A map or maps are required to demonstrate the impact fee areas and will be included in the deliverables. Maps will be developed to show specific projects. A workflow procedure shall be developed will be developed to integrate future or unknown projects. h:\bd_phx\prescott\water model update\prescott water model update project 06192012.docx 7
