Document Description
The Project site is located in unincorporated Los Angeles County, in the northern foothills of the Santa Susana Mountains within the Santa Clarita Valley. The Project includes several entitlements for the creation of 37 lots for the development of up to 510 dwelling units with maximum height of 26 feet to 45 feet, with a mix of attached and detached for-sale condominium units, including 24 affordable for-sale units, 47 affordable senior rental apartments, and one manager's unit; a recreational center and swimming pool; two on-site public streets; private driveways and fire lanes, including multi-purpose trails that would be open to the public; several debris basins; five-foot-wide pedestrian walkways, a water tank, and both improved and natural and preserved open space. The proposed development is clustered in the northeasterly portion of the Project site, and also includes several on-site block and retaining walls. The Project includes 150 acres of natural open space on-site, of which approximately 144 acres would be preserved and maintained in perpetuity through a conservation easement. Off-site Project components include sidewalk improvements, a retaining wall adjacent to The Old Road directly east of the Project site, improvements to The Old Road fronting the Project site, and fuel modification (brush thinning). The Project would include several off-site utility infrastructure component improvements, including utility water lines, upgrades to two existing pump stations, upsizing of existing sewer pipelines, and the construction of three manholes within The Old Road. Additionally, the Project includes the vacation of excess right-of-way in The Old Road and acquisition of an adjacent County-owned parcel (APN: 2826-022-901). The grading would be balanced on-site, and no import or export of soil would be required for the Project. Several on-site access and utility easements are proposed.
