Riverside PZC debates front‑loaded garage limits, setbacks and bonus coverage; asks staff for diagrams and further drafts

The Village of Riverside Planning and Zoning Commission spent the second half of its Dec. 17 meeting reviewing proposed text amendments dealing with front‑loaded garages, driveway widths and a possible bonus building‑coverage incentive intended to encourage rear‑loaded garages.

Staff summarized recommendations dating to 2018 that were not fully carried into the 2020 ordinance and sought commissioners’ direction on several topics: aligning accessory‑structure separation with building code standards, clarifying definitions for front‑loaded/side‑loaded/rear‑detached garages, narrowing visible approach aprons near the street, and whether to offer a building‑coverage bonus (for example, excluding up to 400 square feet of a rear detached garage from the building‑coverage cap) if a homeowner places the garage in the rear yard.

Commissioners generally favored aligning separation requirements with the building code (which can require as little as a 3‑foot separation depending on fire suppression) to reduce nonconformities. On setbacks, several commissioners supported making a 5‑foot setback for attached front‑loaded garages a required standard for new construction rather than only a recommendation. Commissioners repeatedly requested clearer definitions and diagrams to avoid inconsistent application — for example, whether a garage that is parallel to the front façade but behind the front foundation should be treated as front loaded or rear detached.

There was extensive discussion about driveway/apron widths near the street and an existing ordinance allowance that lets the apron extend to the exterior face of a garage to provide pedestrian access. Staff recommended retaining the access allowance but rewording it to prohibit excessive widening beyond what is necessary for an entry and to ensure required tapering back to a narrower driveway width. Commissioners asked staff to provide photographs and diagrams of local examples and to consolidate garage‑related design standards into a single, clearer section of the ordinance.

On the bonus building‑coverage proposal, staff showed illustrative calculations (a 400 sq ft bonus in several zoning districts) and noted that the bonus could increase building coverage materially on small lots; several commissioners expressed concern that giving the bonus without a matching impervious‑surface allowance could undermine stormwater limits on 5,000 sq ft lots. Staff said they would prepare paired scenarios — a building‑coverage bonus combined with impervious‑surface allowances or paired with mandatory semi‑pervious materials — and return with visuals and draft ordinance language. No final action was taken; staff was directed to return with consolidated draft language, photos, and diagrams and to bring the materials back in January for review with a possible public hearing in February.
