Stormwater Fund CIP FY2019-2023 Commission Memorandum REPORT TO: Honorable Mayor and City Commission FROM: Kristin Donald, Finance Director SUBJECT: Adopt the Storm Water Fund Capital Improvement Plan (CIP) for Fiscal Years 2019-2023. AGENDA ITEM TYPE: Consent MEETING DATE: November 20, 2017 RECOMMENDATION: Adopt the Storm Water Fund Capital Improvement Plan (CIP) for Fiscal Years 2019-2023. BACKGROUND: Each year, the City Manager is required to prepare a 5 Year Capital Improvements Plan and submit it to the Commission by December 15th. Similar to recent years past, we are bringing the various parts of the plan forward as items on the Consent agenda. We will be prepared to address questions, if they arise, at the public meeting. The Public Works, City Manager, and other city staff met in October and November to develop the attached Capital Plan for the equipment and capital needs of the Storm Water Fund. Items of Note:  STRM13 – Annual Pipe Replacement – An annual program that provides funding for the design and construction of various pipe rehabilitation, drainage, and treatment projects that improve the structural integrity and conveyance capacity of the City’s stormwater infrastructure network. Unplanned funds allow Staff to respond to 37 infrastructure needs that arise from reoccurring system inspection and partner with other Public Works’ projects, such as local SID street reconstructions when approved.  STRM48 – Annual Pedestrian Ramp Replacement Program has been added to the Stormwater Fund CIP at $100,000 per year. Costs will be split 50/50 with the Street Maintenance Fund. Cost share is appropriate because typically pedestrian ramp improvements also require replacement of stormwater inlets and catch basins. Having funds available for the stormwater related costs of ramp replacement will increase the number of ramps that can be replaced each year.  STRM39, STRM34, STRM31, STRM38- Mechanical Separation Units Downtown Stormwater treatment- These are phases budget for FY19-FY22 that install stormwater mechanical separation units near intersections.  Fiscal year 2017 revenues represent the first fiscal year where our rate-model is fully implement for all 12 months. The changes in revenues over the past 5 years have been driven by our implementation of the full rate model. We are basing our FY19-23 revenue estimates on annual customer growth of 3% per year. This is similar to our most recent Wastewater rate model. Actual revenues should grow depending on the mix of impervious areas/existing infrastructure use as property is annexed and developed. 38 UNRESOLVED ISSUES: None. ALTERNATIVES: As suggested by the City Commission. If the Commission does not wish to adopt this schedule tonight, it can be scheduled for approval on a later agenda. FISCAL EFFECTS: This step in the process has no fiscal effect. Once adopted, the Capital Improvements Plan becomes the basis of the City Manager’s Recommended Budget for FY18.
