The application's description as it appears in City of Boise's record. See the official record

A developer wants to annex about 8.18 acres at 10512 W Hill Road Parkway into Boise and build the Brio Vista Subdivision with 36 buildable lots and nine common lots on a hillside. The request also includes hillside grading approval and variances for sidewalks, driveway length and street standards because of steep slopes. Planning staff recommend approval, but this report does not record a final decision.
