Moorpark Avenue Storm Drain 1. Background: The City's Master Drainage Plan includes the construction of a storm drain on Moorpark Avenue. The design for this project has been completed and the project is ready to advertise for bids. 2. Description: The project design calls for the extension of the existing 60" diameter storm drain located in Moorpark Avenue south of Los Angeles Avenue, northerly across Los Angeles Avenue and then northerly to a point north of First Street. The scope of work also includes the following: a) the construction of a storm drain lateral extending easterly from Moorpark Avenue to Flory Avenue, b) the construction of a second lateral to serve the Metrolink parking lot; and c) the construction of new curb, gutter and sidewalk on the east side of Moorpark Avenue to improve surface drainage. 3. Cost Summary: The following is a brief summary of the cost of the various elements of the Moorpark Avenue Storm Drain: Description Constr ($) Other ($) Total (S) State Highway 980,000 220,000 1,200,000 Flory lateral 60,000 15,000 75,000 MetroLink lateral 60.000 15,000 75,000 1,100,000 250,000 1,350,000 4. Caltrans Participation: Caltrans and the City have entered into Cooperative Agreement providing for Caltrans funding of a portion of the cost of that portion of the Moorpark Avenue storm drain located within the State highway. Caltrans share of construction costs is $280,000. mpksdL ad Storm Drain Project January 1996 Page 2 B. Spring Road 1. Background: The City's Master Drainage Plan also includes the construction of a new storm drain on Spring Road north of Los Angeles Avenue, to serve that drainage area. The subject storm drain project also includes the construction of this storm drain line. 2. Description: The Spring Road storm drain will extend northerly from an existing storm drain located south of Los Angeles Avenue to Flinn Avenue. The project also includes a storm drain lateral extending easterly in Flinn Avenue to serve that area. And finally, the project also includes the construction of new curb and gutter and an asphalt overlay on a portion of Flinn Avenue. 3. Need: It is proposed that the City proceed with the construction of this storm drain at this time for three reasons: a) in order to benefit from economies of scale; b) to provide a storm drain to Flinn Avenue required to adequately address drainage problems on that street prior to needed street reconstruction; and, c) to construct the storm drain prior to the Spring Road resurfacing effort to be undertaken or funded by Caltrans as a part of the highway relinquishment. 4. Cost Summary: The following is a brief summary of the cost of the various elements of the Spring Road Storm Drain: Description Constr. ($) Other ($) Total (S) Main S. D. line 305,000 80,000 385,000 Flinn lateral 115,000 30,000 145,000 Flinn reconstr. 180,000 40,000 220,000 600,000 150,000 750,000 5. Developer Participation: It is the goal of the City to fund this storm drain entirely from developer contributions. A portion of the costs ($32,217.54) have already been paid by the developed property at the northeast corner of Los Angeles avenue and Spring Road (McDonald's). As other vacant properties are developed, they will be conditioned to reimburse the City for their prorata share of the project costs. 6. Caltrans Maintenance Yard: Caltrans has agreed to pay the City $80,000 for a portion of the subject costs when they proceed with the construction of the new Caltrans Maintenance Yard at the east end of Fitch Avenue. npksd3.ad Storm Drain Project January 1996 Page 3 7. Anderson Property: The owner /developer of the vacant property adjacent to the McDonald's restaurant (Anderson) has entered into an Agreement with the City obligating him to pay for his prorata share of this storm drain. The present engineer's estimate for these costs is $77,508.22. 8. Bid Alternates: If deemed necessary to adequately address the concerns described above, the bidding documents will include bid alternates to allow the City to award a contract for the Moorpark Avenue line only. 9. Funding [Spring Rd. Storm Drain]: As stated above, it is the intent of staff to fund the Spring Road storm drain by contributions from the developers of vacant property within the drainage area served by this facility. It is recommended that initial funding of this work be provided by the L. A. Ave. AOC and the MRA on a 50 % -50% basis, and that these expenses be repaid by developer contributions as they are received. A summary of project funding is set forth in Section E of this report. 10. Funding [Flinn Avenue Storm Drain & Flinn Avenue Reconstruction]: It is recommended that the funding of the Flinn Avenue storm drain lateral and the Flinn Avenue street reconstruction be provided by the Gas Tax Fund and the MRA on a 50 % -50% basis. Again, a summary of project funding is set forth in Section E of this report. 11. Flinn Avenue Storm Drain & Reconstruction: It should be noted that it is not possible to construct the Flinn Avenue storm drain lateral, or to reconstruct Flinn Avenue with new curb and gutter flow line elevations, without constructing the entire Spring Road storm drain project. The existing in adequate storm drain in Spring Road is too high to allow the connection of the new Flinn Avenue lateral. In addition, it is not recommended that the Spring Road resurfacing project to be funded by Caltrans proceed prior to such work. mpksd3.ad Storm Drain Project January 1996 Page 4 C. Utility Conflicts All of the utilities in conflict with the project have or will be relocated by the utility company or special district. A summary of those activities is as follows: Calleguas Municipal Water District: Two major water lines on Moorpark Avenue will be relocated within the next few weeks. County Waterworks District No. 1: A number of the District's facilities will be relocated by them or their contractor in concert with the City's storm drain project. Shell Oil Company: A gas line will be relocated by the utility in concert with the City's project, at both the Spring Road and the Moorpark Avenue intersections. Southern California Gas Company: A number of gas mains and services laterals will be relocated by the utility in concert with the City's project. Southern California Edison Company: An underground SCE facility will be relocated by the utility in concert with the City's project. D. Phasing and Traffic Control The phasing and traffic control plans for the Moorpark Avenue storm drain were reviewed by the City Council on June 1, 1994. The City Council's comments were incorporated into the design and Caltrans permit application and forwarded to Caltrans. Caltrans may require work in the two intersections on Los Angeles Avenue to be performed at night in order to mitigate traffic congestion. An Add Alternate bid will be included in the bidding documents for such work should it be required. Construction will Spring Road until been completed. mpksd3.ad be phased so that work will not commence on after construction on Moorpark Avenue has Storm Drain Project January 1996 Page 5 E.
