Approved: 14-foot retaining wall for hillside home's rear yard

The Boise Hearing Examiner approved a variance allowing a concrete retaining wall about 14 feet tall to replace a failing block wall that holds up a sloped rear yard. A fence or guardrail up to 5 feet may be added on top, and a Category II Hillside permit is still required before building permits are issued.

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

The applicant wants to replace a failing six-foot retaining wall behind a single-family home at 4814 W Roberts Road with a 14-foot-tall concrete wall in the rear setback. The wall would connect to an existing 14-foot wall on neighboring lots to the east and taper down on the lot to the west. It would stabilize a steep slope above the Hillcrest golf course maintenance area on a 0.34-acre lot.
