After studying the problem, the scope of the storm drain was extended to include drainage problems on Flory Avenue and at the new Metrolink parking lot. Because Moorpark Avenue is a state highway, Caltrans has agreed to participate in the cost of the storm drain improvements in Moorpark Avenue. The Caltrans Cooperative Agreement and the conceptual plans were reviewed and approved by the City Council on 3/16/94 . A traffic control and detour plan were reviewed by the City Council on 6/1/94 . It is anticipated that we can have Caltrans' approval of all plans so we may begin construction late summer. In order to expedite this plan review, we submitted the plans, including City Council's comments on the Traffic Control and detour plans to Caltrans last week. DISCUSSION A. Limits and Scope The Moorpark Storm Drain will extend from the Metrolink Parking lot on the north, run southerly across Los Angeles Ave. , and tie into an existing storm drain approximately 230' south of Los Angeles Ave. The Metrolink Parking lot drain will extend from the westerly end of the southerly Metrolink Parking lot, run parallel to the driveway, and tie into the Moorpark drain just north of First Street. The Flory drain will begin at Flory Avenue, south of Third Street, and run westerly along an existing drainage course between homes, and tie into the Moorpark drain. The design improvements include: storm drain pipe, catch basins, and; curb, gutter, sidewalk, and wheelchair ramps on the east side of Moorpark Avenue between First and Third Streets, and between the railroad tracks and the Metrolink driveway. This work will include all appurtenant adjustments and transitions with the existing pavement, sidewalk, and utilities. Plans and specifications will be submitted under a separate item. Agenda Report June 3 , 1994 Page 2 B. Phasing and Traffic Control The phasing and traffic control plans were reviewed by the City Council on June 1 , 1994 . The Council's comments were incorporated into the permit application and forwarded to Caltrans. Staff is currently working with the residents along Moorpark Avenue and the School District to coordinate the detours and construction schedules. Construction of the Storm Drain in Moorpark Avenue and Los Angeles Avenue is proposed in four phases: 1 . In Moorpark Avenue south of Los Angeles Avenue. 2. In Moorpark Avenue, from just south of Los Angeles Avenue northerly to the centerline of Los Angeles Avenue. 3. From the centerline of Los Angeles Avenue northerly to just north of Los Angeles Avenue in Moorpark Avenue. 4. In Moorpark Avenue from just north of Los Angeles Avenue northerly to the Metrolink Parking Lot. Construction is proposed to begin with Phase 1 and proceed northerly phases by phase. The specific details for traffic control of each phase were discussed and approved by the City Council on 6/1/94 with the following amendments: 1. Coordinate impacts with School District; 2. Survey of residents of Moorpark Avenue regarding night work; 3 . Rerouting trucks to Grimes Canyon instead of High Street. Night work in the intersection of Los Angeles Ave./Moorpark Ave. and the three requested amendments above have not been included in the current plans, specs, or contract documents, but will be included as add-alternates after approval from Caltrans. All plans have been submitted to Caltrans. Staff has met with representatives of the Moorpark Unified School District and Prunner Ambulance Service to discuss the potential impact of the subject project on their operations. Both stated that they believed that they will be able to accommodate the anticipated disruption in traffic patterns. Agenda Report June 3 , 1994 Page 3 C. Caltrans Participation A year ago at this time it was estimated that the Caltrans' share of the project would be approximately $400 ,000. Since that time, the City and Caltrans have worked to complete a Hydrology Study to determine the Cost Share Ratio. That study determined Caltrans' share to be forty per cent (40%) of eligible construction cost, not to exceed $300 ,000. The City and Caltrans have entered into a Cooperative Agreement stipulating this level of participation by Caltrans. Caltrans eligible costs include pipe, manholes, junction structures, catch basin, and pavement, curb and gutter restoration, wheelchair ramps and the repair of pavement for drainage related to work along Moorpark Avenue. Ineligible costs include sidewalks, curbs and gutters along Moorpark Avenue and the extension of the Storm drain beyond the limits of the State right-of-way. Final plans have not been approved by Caltrans, but an Engineer's estimate for the improvements has been prepared. Total cost of all improvements is estimated to be $1 , 166 ,000 . This includes a 10% contingency and design and construction Engineering costs. D. Fiscal Impact: 1 . Total Project Cost Estimate Past Future Expenses Costs Design 92 ,950 Estimated Construction Cost $1 ,060 ,000 Contingencies (10%) 106,000 $1 , 166 ,000 Engineering (10%) 164,000 Total Costs $92,950 $1,330,000 2 .

Appropriation It is recommended that the appropriation of the funds identified in the proposed FY 1994/95 Budget figures identified above, be deferred to the upcoming adoption of next year's Budget. E. Project Schedule It is anticipated that a contract will be awarded on August 17, and that construction will be completed by December 1994 . F. Traffic Control and Staging Plans At a recent meeting of the City Council , the draft Traffic Control and construction staging plans were presented to the City Council for review. A final detour and traffic control plan, along with Caltrans and the School District's comments, will be provided to the City Council when they become available. RECOMMENDATION: Staff recommends that City Council take the following actions: 1 . defer amending the appropriations for the subject project to the adoption of the FY 1994/95 Budget; 2. approve the project design plans, subject to Caltrans' approval; and, 3 . authorize staff to advertise for receipt of bids for the subject project.
