Revisions include an expanded flat rear yard area requiring additional fill, multiple retaining walls, and the inclusion of accessory structures on a single family parcel located within a Town -identified Scenic Hillside area located at 2460 Tassajara Lane. PROTECT DESCRIPTION The project includes a Development Plan request (DEV23-0014) to review landscaping for a single family residence with a previously approved Development Plan (DEV20- 0010). This lot was created as part of subdivision MS 853-2021 which conditioned any development on the lot to be reviewed by the Design Review Board. This lot is also partially located with a Town -identified Scenic Hillside area which requires the approval of a Development Plan. Development Plan DEV20-0010 was reviewed and approved by the Design Review Board on March 25, 2021, which allowed for the construction of a 4,618 +/- square foot residence with a 419 square foot attached ADU and a 523 square foot garage. EVALUATION Landscape The subject site plan appears to be consistent with the approved development plan and the required items outlined for additional review: • The project proposes to extend the flat pad toward the rear of the residence which includes the addition of fill and terracing retaining walls. The terraced retaining walls will comply with retaining wall standards which includes a maximum height of six feet and spacing the walls at a distance equal to or greater than the height of the tallest bordering retaining wall. • All trees are a minimum of 15-gallon container sizes and the shrubs are of 5-gallons and 1-gallon in size. Landscaping is proposed between the terraced retaining walls and surrounding the flat portion of the site. • The project proposes the addition of accessory structures including a pool, fire pit, and the possibility of a future cabana. RECOMMENDATION Approve revised landscape plans for previously approved Development Plan request DEV23-0014. Revisions included an expanded flat rear yard area requiring additional fill, multiple retaining walls, and the inclusion of accessory structures on a single family parcel located within a Town -identified Scenic Hillside area located at 2460 Tassajara Lane.
