Proposed Improvements The proposed improvements closely match the conceptual planning for the site specified in the Happy Valley Specific Plan. The development proposes one public street, Serenity Lane, and two private driveways. One of the private driveways will provide access to lots 6-9 with a fire truck turn-around at the south end of the private driveway. Another private driveway (Sleepy Head Lane) will provide access to the Wentworth Property until it is fully developed. It is anticipated that Sleepy Head Lane will be offered to the City as a public street with the future sub-division of the Wentworth property. As such, Sleepyhead Lane is being constructed to City public street standards. The existing hiking/equestrian trail which was constructed with the Callippe Preserve Golf Course project will be extended from the south end of the Tract in a north-westerly direction to Happy Valley Road. The public street streetlights, storm drain systems, sanitary sewer and water systems serving this project, as well as the hiking/equestrian trail, will be maintained and operated by the City. The storm drains and retaining walls within the private lots, City-owned open space (Parcel 3), and private driveways will be the responsibility of the property owners and Homeowners Association. An exhibit is also included in the CC&Rs identifying the areas to be maintained by the Homeowners Association, which include Parcel 3, the open space parcel, with a fire resistant landscaping barrier; retaining walls at the bottom of the slope west of lots 10 and 11; private driveway and storm drain system serving lots 6-9; entrance structures including the decorative lights; and decorative concrete paving at the project entrance. Improvements on Happy Valley Road The developer has submitted improvement plans to Alameda County in order to obtain an encroachment permit to construct improvements required for street and utility tie-ins on Happy Valley Road. Bio Retention Features The developer has proposed bio retention areas on each individual lot to treat storm water as required by the Alameda County Clean Water Program and State Water Board. The developer's soils engineer and City staff have reviewed the proposal and found it to be in substantial conformance with the current requirements. It will be each homeowner's responsibility to maintain these bio retention areas. The Homeowners Association will also have rights to enter and maintain these facilities if individual homeowners fail to maintain them. These bio retention areas have been shown on the [mal map to preclude the construction of future improvements such as swimming pools or accessory structures within these areas. SR 06: 109 Page 3 of 4
