On January 28, 2019, the City Council approved the final plans and specifications for the project and authorized staff to proceed with seeking bids for construction. The construction contract has been awarded to Ortiz Enterprises Inc. with construction to start Monday, February 17, 2020. Construction will be completed within 18 months of commencement.
Project construction falls into four main phases with this tentative schedule:
Phase 1: February 2020 through March 2020 - Traffic control and project fencing from Sepulveda to Elenda, clear and grubbing of median park, and hardscape removal.
Phase 2: April 2020 through January 2021 - Removal of soil and installation of stormwater storage gallery and infiltration system, construction of the realigned median park from Sepulveda to Elenda, and construction of new raised median island on Culver Blvd.
Phase 3: February 2021 through August 2021 - Construction of new sidewalks, paver parking areas, street lighting, and new traffic signals on Culver Blvd. at Harter Ave. and Huron Ave.
Phase 4: September 2021 - Slurry seal of Culver Blvd., final striping, and project completion.
The Culver Boulevard Realignment Project is the continuation of the widening of Culver Boulevard that was completed by Caltrans as part of the 405 Freeway widening in 2009. The Public Works Department is excited about this project as it will resolve traffic issues along this reach of Culver Boulevard; and provide for a safer and more aesthetically pleasing street. The eastbound and westbound lanes of traffic is proposed to be separated with a new raised median.
The project also includes the Urban Runoff Infiltration and Retention Project. In order to comply with the Los Angeles Regional Water Quality Control Board’s Municipal Separate Storm Sewer System Permit (Order No R4-2012-0175) and the Enhanced Watershed Management Program Plan, the City proposing to incorporate structural storm water Best Management Practices (BMP’s) as part of the Culver Boulevard Realignment Project.
The structural BMP being proposed are infiltration galleries for groundwater recharge and retention basins to treat and reuse captured urban run-off to irrigate the local landscaping proposed along the raised median. The infiltration galleries and retention basins will be constructed under the raised bikeway/pedestrian/landscaping median between Culver Blvd and little Culver Blvd. Additionally, BMPs such as bio-swales and drywells will be included in the design to address surface run-off from Culver Blvd.
There are two existing storm drains, 87-inch and 66-inch diameters, passing through the project site at Sepulveda Boulevard and Harter Avenue, respectively. These two storm drains will be the primary source of storm water and urban run-off. The project site has the volume capacity to treat the first 1.1 inch of rain from approximately 344 acres.
All storm water and urban run-off will be pre-treated using multiple treatment systems prior to entering either infiltration galleries or retention basins.
Pursuant to the California Environmental Quality Act (CEQA) guidelines, an Initial Study (IS) determined that the project will not have a significant adverse impact on the environment with mitigation incorporated. A Mitigated Negative Declaration (MND) finding is appropriate.
