Background The city’s CIP calls for the replacement of the existing retaining wall along the north side of Park Drive between Bayshore Drive and 4650 Park Drive. The existing retaining wall was constructed when this segment of Park Drive was widened in 1989. Staff have determined that this wall is nearing the end of its design life and requires replacement. The earthen embankment supported by the retaining wall is highly eroded resulting in the shortened service life of the facility. Sediment eroded from the slope during rain events deposit onto the sidewalk along Park Drive resulting in temporary closures. City street maintenance and operations crews are dispatched to this location following significant rain events to clear the deposited debris and restore pedestrian access. The Project will replace and extend the existing retaining wall, stabilize the slope, modify the existing drainage system and provide street improvements on the segment of Park Drive between Marina Drive and Bayshore Drive. As part of the public outreach plan, the Project was circulated for public review and comment. Staff received a request to install a new pedestrian crossing with rectangular rapid flashing beacons (RRFB) on Park Drive at the intersection with Marina Drive. This improvement will provide controlled pedestrian access between the multi-housing units on the south side of Park Drive to the on-street parking on the north side of the street. The RRFB crossing also enhances pedestrian safety and facilitates access to the Agua Hedionda Lagoon north shore public entrance at the end of Bayshore Drive. Currently, the only controlled crosswalk on Park Drive within this vicinity is at the intersection with Neblina Drive, approximately 450 feet east of Bayshore Drive, which is also supported by RRFB. The requested RRFB crossing provides a controlled pedestrian crossing on the western approach to the Agua Hedionda Lagoon north shore public access. Item 1 Oct. 4, 2021 Item #1 1 The existing Class II bikes lanes on Park Drive currently terminate at west end of the project area at Marina Drive. This project will extend these Class II bike lanes by an additional 600 feet to Bayshore Drive and on street parking will be maintained in both sides of the roadway. The street will be restriped for additional bike lane improvements when the street is slurry sealed within the next few years. Staff recommend that the proposed RRFB crossing be constructed at the intersection of Park Drive and Marina Drive. Necessary Council Action Staff will finalize the Project construction plan, specifications and cost estimate, and request authorization from the City Council to advertise for constructions bids. Next Steps Staff will finalize the construction plans for the Project following the Traffic and Mobility Commission’s review and feedback. A Coastal Development Permit must also be obtained from California Coastal Commission (CCC) prior to the City Council’s authorization to advertise for construction bids. The permit application will be submitted late Fall 2021 but the CCC may take over a year to process the permit. Staff coordinated closely with the CCC throughout the design phase to expedite the permit processing time. Once the Coastal Development Permit is obtained, the improvements will need to be constructed between September 15 and February 15 in accordance with the CCC request. Constructing the improvements during these months will avoid both biological impacts during the bird nesting season (February 15 to September 15) and pedestrian access impacts to the Agua Hedionda Lagoon north shore entrance during the summer tourist season.
