14th Avenue/Bonita Lagoon Storm Drainage Improvements
In September of 1992 the Board of Supervisors approved construction of a drain/culvert system along a portion of 14th Avenue, 15th Avenue and East Cliff Drive with an outlet at Bonita Lagoon.
This project was designed to deal with a drainage system that was under sized and unable to deal with heavy rainfalls which led to regular flooding problems in the neighborhood.
In response to the concerns of area residents about the possible increase of flows to Bonita Lagoon, an agreement was made with the State to plant approximately 1500 native plants to help fortify the protective berm on the ocean front. The water quality of the lagoon was maintained by installing three silt and grease traps.
Completion Date: February, 1993
15th Avenue/Webster Thurber Channel Drainage Project
In June of 1990, the Board of Supervisors approved plans and specifications for the construction of storm drainage improvements for 15th Avenue and Webster Street. This area in Live Oak lies between Capitola Road and Highway 1. The project resolved long-standing drainage problems that caused flooding in he surrounding neighborhoods.
Completion Date: Winter, 1990
30th, 32nd, 33rd Avenues Drainage
This project included the construction of storm drain improvements on 30th, 32nd and 33rd Avenues in the Pleasure Point area of Live Oak. It included curbs, gutters and sidewalks on 30th Avenue, and re-paving of all the public streets in the area.
Community meetings and a survey helped to determine the preferences of the neighbors. This included the limited installation of sidewalks and narrow travel lanes.
The Coastal Commission permit process delayed the start of this project until early in 2001. Conditions recommended by the Commission to preserve and enhance public access to the coast and beach included preservation of on-street parking for public use and installation of high tech storm water filtration units. As well, the County agreed to perform a five-year water quality monitoring program in the area to define the best methods to reduce run-off pollution to Monterey Bay.
34th, 35th, 36th, 37th Avenues Drainage
The purpose of this project was to improve storm drainage facilities in the area between 34th and 37th Avenues and East Cliff Drive and Floral Drive. The construction helped to reduce the chronic flooding on neighboring properties during the winter storm season.
This storm drainage system ties into the two storm drain outfall structures located along East Cliff Drive at the 34th and 36th Avenue intersections. Silt and grease traps help reduce the level of urban contaminates reaching Monterey Bay.
Completion Date: May, 1991
Mission Drive Improvement Project
Due to the amount of runoff coming from the hillsides above the road, and the lack of storm drain facilities in the Mission Drive area between Soquel Drive and Patterson Lane, there were significant drainage problems causing flooding during high rainwater events. The new drainage system was constructed to tie into recent storm drain improvements done in the Commercial Way area, allowing the runoff to empty into a drain shed capable of sustaining flow from a 100-year storm event.
This drainage improvement project was coordinated with the construction of site improvements at Dominican Hospital. As part of the conditions of their development permit for improvements at the Soquel Drive campus, Dominican Hospital constructed curb, gutter and sidewalk improvements on the east side of Mission Drive.
Completion Date: Fall, 1997
Prather Lane/Winkle Avenue Storm Drainage Project
In addition to solving long standing drainage problems in the Prather Lane and Winkle Avenue area of Soquel Drive, this project included construction of a new cul-de-sac on Lillian Way, the access to the soon-to-be constructed Winkle Farm Park. Without this project, construction of the new park would not have been possible.
Completion Date: June, 1991
