This draft SWCP was never finalized or implemented. As part of the update, the City is seeking to understand what information within the draft is still applicable and what new information or data is needed. The SWCP will include an analysis of the existing stormwater system, including a list of existing deficiencies, a set of best management practices (BMPs) and design standards for future developments, a capital improvement project (CIP) list to address deficiencies and anticipated growth, and a rate study to evaluate the capacity of the existing Stormwater Utility (SWU) rate to meet the needs identified in the CIP. The rate study will include an analysis of additional rate structures. This Scope of Work is based on published regulatory requirements for municipal stormwater systems known at the time of this writing. If new or expanded regulatory requirements are published during the course of this project, a contract amendment, along with a scope of work and fee estimate, can be provided for the additional work needed to satisfy the requirements. All available resources from the previous planning work will be utilized to minimize the level of effort necessary for this SWCP. To complete the activities within the schedule, RH2 proposes to utilize two subconsultants as follows: Northwest Hydraulic Consultants (NHC) - Hydrologic Modeling. • FCS GROUP- Rate Study. Task 1 - Project Management Objective: Manage the project team, maintain project filing, and monitor scope and budget. It is estimated this project will extend approximately six (5) months.

If new facilities and/or maintenance activity needs are identified, recommendations for additional staffing will be provided. Approach: 6.1 Summarize the City's current stormwater code and regulations and identify if gaps exist that should be revised. 6.2 Review 2019 through 2024 NPDES permit requirements and the City's stormwater program to identify gaps related to O&M, inspection, enforcement, or review of applications for new and re -development projects. Provided by City: • Current City stormwater regulations and access to City attorney for consultation. RH2 Deliverables: • A copy of the effective stormwater code as an appendix of the SWCP in PDF format. • Summary of gaps in the City's stormwater program that need to be filled to meet 2019 through 2024 NPDES permit requirements in PDF format. Task 7 -- Stormwater Utility Rate Study Objective: Perform a Utility Rate Study to match resources with capital projects and future incremental operating costs identified in the gap analysis. The rate analysis will demonstrate the financial viability of the utility during execution of the CIP. This financial viability analysis considers the current financial condition of the utility, the financial impact of executing the CIP, the sufficiency of utility revenues to meet current and future financial and policy obligations, and the affordability of utility rates. The study will provide two (2) capital funding and rate adjustment strategies for consideration. Meet with City staff to review draft findings prior to submitting the final financial chapter.

Review and validate data. 7.3 Perform a revenue requirement forecast and capital funding analysis. The revenue requirement forecast will involve the following subtasks: • Review and update (if necessary) the City's existing financial policies (e.g., operating and capital reserves, capital funding strategies, debt management, etc.). • Evaluate capital funding options and develop a capital financing plan for the list of CIP projects identified in the SWCP. The financial plan provides for up to two (2) funding strategies. This can cover either two (2) different versions of the CIP list, or two (2) different rate strategies on a single CIP project. The analysis will include a forecast of capital funding needs, borrowing requirements, and associated cash flows and cash balances over the study period. • Evaluate operating forecast based on the most recent budget documents available. In addition, incorporate growth forecasts, integrate additional O&M expenses, if any, resulting from the CIP list, and incorporate any other known changes in operational requirements. • Integrate financial policies, capital financing impacts, and the operating forecast to develop an operating cash flow over the study period. Compare forecasted financial requirements against forecasted revenue under existing rates to determine annual and cumulative revenue adjustments needed to ensure financial sustainability overtime. • Apply annual required rate adjustments (Revenue Needs Assessment) "across-the-board" to the existing stormwater rate structure and develop a rate forecast for the study period. Note: this subtask does not include changes to the existing stormwater rate structure applied per Equivalent Service Unit. 7.4 Prepare the financial chapter of the SWCP. Review preliminary results with RH2 and City staff via one (1) Web-ex/remote meeting. • Finalize results based on proposed scenarios with RH2 and City staff via one (1) Web- ex/remote meeting.
