BACKGROUND Tract 7162 is asingle-family detached, custom lot, residential subdivision developed by Heartwood Communities, Inc. The site is located west of Callippe Preserve Golf Course and south of Happy Valley Road at the junction of Happy Valley Road and Alisal Street, as shown on attached vicinity map. In addition to 12 single family detached custom residential lots, Tract 7162 also created Parcel A and Parcel B. Parcel "A" is dedicated to the City of Pleasanton for the Golf Course and related purposes, and Parcel "B" is dedicated to the City of Pleasanton as open space. Improvements The development created one public street, Serenity Lane, and two private driveways. One of the private driveways provides access to lots 6-9 with a fire truck turnaround at the south end of the driveway. The other private driveway (Sleepy Head Lane) provides access to the Wentworth Property. Sleepy Head Lane may be offered to the City as a public street with the subdivision of the Wentworth property. The existing Class "C" equestrian/pedestrian trail which was constructed with the Golf Course project, has been extended from the south end of the tract in a northwesterly direction to Happy Valley Road. This trail will be maintained by the City. The streetlights, the storm drain systems, sanitary sewer and the water systems serving this project are public and will be maintained and operated by the City, with the exception of the storm drains and retaining walls within the private lots and private driveways, which will be the responsibility of the property owner and the homeowners' association. The area to be maintained by the homeowners' association includes the Parcel "B" open space area, including fire-resistant landscaping; a retaining wall at the bottom of the slope, west of lot 10 and 11; the private driveway and storm drain system serving lots 6- 9; and entrance features including decorative concrete paving. As mentioned, Sleepy Head Lane is a private driveway to the Wentworth property. This driveway will remain private until such time as the Wentworth property develops. The water main within this driveway is public and will be maintained by the City. Improvements on Happy Valley Road The developer is working with Alameda County staff to obtain acceptance of the work within the County right-of-way (along Happy Valley Road). Bio Retention Features The developer has constructed bio retention areas on each lot to treat storm water as required by the Alameda County Clean Water Program and State Water Board. It will be the homeowners' association responsibility to assure the maintenance of the bio retention areas on each lot. These bio retention areas have been shown on the Final Map to prevent future improvements, including, but not limited to, swimming pools and accessory structures, within these areas. Page2of3
