Commissioners give concept feedback, continue Alta Vista remodel with exceptions study

The Historic Landmarks Commission on Friday reviewed a concept proposal for 1315 Alta Vista Road, a contributing historic resource in the Lower Riviera Special Design District, and continued the item with specific design and zoning-exception guidance.

Applicants Vanguard Planning described a project that preserves the street-facing portion of a modest craftsman-era house while adding approximately 1,300 square feet in a two-story rear addition and converting an undersized detached garage into a code-compliant attached garage. Staff planner Kelly Rodison said the project requires a package of findings for project compatibility, major alterations and minor zoning exceptions: three relocated windows in the northwest setback and an increase in garage height from 9 to 11 feet.

Applicants said the addition is being pushed to the rear to avoid changes to the front facade; the site slopes downward and the added square footage is largely below the existing plate as a lower level. They told the commission the detached garage is nonconforming and cannot accommodate modern vehicles, so attaching and raising the garage would provide usable parking.

A neighbor, Dermot Downs of 1321 Alta Vista Road, urged care on construction impacts and asked whether the narrow setback along the north property line would remain. Staff and applicants said the storage area on the north is part of the existing footprint and maintained existing setbacks; the Fire Department reviewed the plans and reported acceptable emergency access. Staff also noted that because the building is historic, Title 24 energy-code window requirements can be addressed under the historic-building code when appropriate.

Commissioners praised the approach that preserves the primary street-facing facade and asked applicants to return with refinements including: window proportions and muntin patterns that relate to the historic front windows; more careful detailing for entry columns and porch supports; tile-cap parapet details; improved rear elevation composition so the addition reads as a cohesive whole rather than an obvious add-on; and a study of landscape and retaining-wall details for the sloped lot. Several commissioners suggested planting one or two trees in the rear or parking-planter areas where feasible.

The commission moved to continue the item indefinitely with the comments recorded on the record and voted unanimously to continue (roll-call vote: Commissioners Enzberg, Lundbeck, McClure, Butler, Dorton, Drury and Chair Grumbine — all "yes").

Why it matters: The project proposes additions and minor zoning exceptions to a property that contributes to a historic neighborhood; the commission's feedback focuses on preserving the visible historic character while allowing the owner to modernize and expand in the rear.

Closing note: Staff will forward the commission's comments to the applicants; applicants will return with revised drawings addressing the items above.

Provenance: Commission opened the item at the start of the agenda presentation (topic intro at 3045.165) and the roll-call continuation vote occurred at 6343.17.
