1 7 August 13, 2009 TO: FROM: Mayor and Council City Manager SUBJECT: INFRASTRUCTURE CAPITAL IMPROVEMENT PLAN REPORT The Director of Public Works and his fine staff prepared and submitted to you a good overview of priority capital improvement projects as requested by the City Council at your Strategic Plan Workshop. The City of South Lake Tahoe needs an economic development strategy and Strategic Plan that grows local businesses, brings needed and desired local businesses to town to serve the needs and wants of residents and grows local revenues, diversifies the local economy and provides balance to it. Investments can and should be made in important public improvements. The expenditure of one-time funds however leaves no funds for work in future years. The focus on needed capital improvements by policy makers is appreciated and welcome. The focus on revenue growth (outside of raising taxes or placing other burdens on business) requires concerted and concentrated action if we are to maintain a viable capital improvement program.

2 Cit,.nouth L1ie Tahoe "making a positilje difference now" Staff Report City Council Meeting of August 18, 2009 Dt: August 6, 2009 To: Fr: David Jinkens, City Manager John Greenhut, Director of Public Works Re: Approve FY Infrastructure Capital Improvement Plan Recommendation: Approve attached FY Infrastructure Capital Improvement Plan (CIP) list for priority street related projects and approve inclusion of the projects into the FY CIP budget submittal. History & Discussion: At the City Council Strategic Planning Session on August 4, 2009, staff was directed to prepare a listing of priority infrastructure projects for the upcoming fiscal year and to prepare a five and ten year CIP. Attachment A contains a listing and estimated costs of the staff recommended priority projects for FY The five and ten year CIP will be presented at a future City Council meeting. In developing the attached list of projects, staff utilized the Pavement Management System (PMS), the Drainage Master Plan (DMP), as well as conferences with maintenance staff and field inspections. The list represents projects related to roadways and drainage only. There was no consideration of other Cityowned facilities. The list includes: CIP-Roadway Rehabilitation-This is a continuation of the overlay program that emphasis arterial and collector roadways. This is the primary area of focus based upon recommendation contained within the Street Repair Plan. The street selection was made by the PMS. The work involves asphalt milling and the placement of a structural overlay. CIP-Roadway Preservation-The list of streets were selected upon review of the PMS. The streets that were selected had a PCI of between The list was further reduced to eliminate streets where no known utility projects or water quality projects are planned in the near future. This is the initial effort to implement a preservation program. The streets will be patched by City staff and then a contractor will crack seal, place an asphalt rubberized chip seal, and then an asphalt seal coat will be placed over the chip seal. CIP-Drainage Infrastructure Repair-This list contains projects that either collect water on the streets, convey water from streets, or improvements to existing drainage infrastructure. The project scope is as follows: Public Works Department Services Center' 1052 Tata Lane' South Lake Tahoe, CA (530) (530) FAX

3 Staff Report - Capital Improvement Plan August 18, 2009 CC Meeting Page Two Overlook Court -Ruby Lane This area has been hit by several thunderstorms in the past three years. These high run-off events have revealed problems in the storm water collection and conveyance system in the Overlook Court to Ruby Lane drainage area. The storm drain inlets are easily clogged which results in storm water jumping the curb and flowing overland. The overland flows cut down through private property resulting in localized flooding and heavy debris flows. The proposed work will include replacement of drainage inlets, construction of storm drainpipe and reconstruction of overland channels. Park Avenue Basins and North Ditch The water quality treatment efficiency of the Park Avenue Basins can be enhanced through several identified modifications to the basin storm drainpipe system. In addition, sections of the North Ditch are in danger of collapsing. The proposed drainage improvements will allow better utilization ofthe lower treatment basin and address needed maintenance to the North Ditch channel. Third Street & Helen The City has received recurring complaints about flooding downstream of the Third Street and Helen Avenue Intersection. The storm drain collection system at this location consists of standard drainage inlets that are connected to a drywell leach field. Project work could include the construction of a detention basin, storm drain piping, and downstream channel work. Stateline Storm Drain Outfall A drainage system report prepared by consultant, Poggemeyer Design Group included a complete analysis of the existing storm drainpipe conditions. The report identified that most of the storm drainpipe was in good condition. However, the outlet section of the storm drain is in very poor condition and there is a significant amount of debris inside the pipe. Proposed project work includes replacement of the outfall section of pipe, construction oftwo manholes in the 900 feet of storm drainpipe, and cleaning the pipe of debris. Bill Avenue Drainage A section of public storm drain crossing through private property has failed. The area is prone to flooding during high runoff events. The proposed project work includes acquiring a drainage easement or conservation easement and either repairing the storm drainpipe and/or performing channel restoration work. Upon approval, the Public Works Department will amend the previously submitted proposed CIP budget to include this work.

4 Staff Report - Capital Improvement Plan August 18, 2009 CC Meeting Page Three Financial Implications: There is no current available funding source for the projects other than the General Fund or the General Fund Reserve. Upon completion of the work, there should be a reduction in required maintenance. Proposed cost estimate is as follows: CIP - Roadway Rehabilitation $970,982 3 CIP - Roadway Preservation $484,211 CIP - Drainage Infrastructure Repair $610,000 Total $2,065,193 I Reviewed and Approved by: Attachment: FY Infrastructure Capital Improvement Plan (CIP) c: Christine Vuletich, Director of Finance Debbie McIntyre, Accounting Manager Jacqueline Mittelstadt, City Attorney Patrick Enright, Deputy City Attorney 11:\data-a-d\cip\council \staff report one year cip doc David Jinkens, City Manager
