Grass Valley DRC approves revised cupola base and patina plan for Maria’s patio

The Grass Valley Development Review Committee on March 25 approved revisions to the patio at Maria’s Mexican Restaurant at 126–226 East Main Street, clearing design changes to cupolas and corrugated metal siding and adding conditions to reduce the cupola base height and alter finish treatments.

Senior planner Lucy Rollins told the committee the item was a continuance from the March 11 meeting and that the applicant had already installed one cupola and invited DRC members to inspect it on-site. "The proposal heard on March 11 was for the installation of metal cupolas on the roof of the patio structure ... and corrugated metal siding on the side fronting East Main Street of that patio," Rollins said.

The committee approved the plan revisions with several modifications. City Planner Amy Wilson made the motion to approve the development review permit as presented in the staff report with the added conditions that the cupola attachments be painted to match the roof color, the base of the cupolas be shortened by eliminating one of the stacked mounting boxes shown in the plans, and the corrugated metal siding be treated to accelerate oxidation (a patina) so the metal will blend with the building colors. The committee adopted findings that the project is categorically exempt under section 15.301, Class 1, of the California Environmental Quality Act (as reflected in the staff report). The motion passed with four ayes.

Robert Wallace, representing the applicant, described onsite coordination and said he supported adjustments after committee review. "I saw the scale of the cupola relative to the roof and the structure ... and I do think it's an appropriate scale for that roof," Wallace said, adding the metal siding and cupola help screen the undercarriage and provide light protection for diners.

Several committee members and reviewers raised concerns about overall height and visual impact. One committee member noted the cupola drawings showed a “box on a box” and urged reducing overall height by modifying the lower mounting box. Another suggested painting roof attachment hardware to match the roof so fasteners would blend in. Members also discussed the corrugated metal’s appearance from the street and recommended accelerating oxidation so the metal would patina and better match surrounding materials; one committee member specifically suggested a vinegar solution as a low-cost method to begin oxidation.

Applicant representatives said the patio structure was originally built under an expedited building permit during the COVID period and later dressed up with siding and cupolas; they acknowledged the sequence of construction and design review had been out of the usual order. The applicant said safety bollards on the street-facing edge were intended to protect diners from cars and that exterior corrugated metal placed on the street side would be subject to repeated impacts.

The committee’s approval requires that construction and final details conform to the conditions in the staff report and the modifications decided at the hearing. No further vote tallies by individual committee members were recorded in the transcript beyond the four-aye tally.

The committee moved on to other agenda items after the approval; staff will process the building permits and verify the modified cupola base, painted attachments, and patina treatment in final submittals.
