Summary
New development and major renovations in La Mesa's Mixed Use Overlay Zone, covering RB-D and C-D lots along El Cajon Boulevard, University Avenue and La Mesa Boulevard near the Village and the Spring Street Trolley Station, must go through Urban Design Review against the city's Design Guidelines for Properties in the Mixed Use Overlay Zone, per La Mesa Municipal Code § 24.18.040(F).
F.Design. New development and major renovations in the MU Zone are subject to Urban Design Review by the city's design review board and city council per Chapter 24.11. To encourage design creativity, flexibility, and quality design that is sensitive to the surrounding context and unique site conditions, design guidelines specifically for mixed use have been prepared. For design guidance, obtain copies of the city's Urban Design Program Report and Design Guidelines for Properties in the Mixed Use Overlay Zone.
Full Breakdown
Chapter 24.18 establishes the Mixed Use Overlay (MU) Zone for RB-D and C-D lots that the La Mesa General Plan designates 'Mixed Use Urban,' concentrated along El Cajon Boulevard, University Avenue and La Mesa Boulevard, and near the Spring Street Trolley Station, per Section 24.18.010. Under Section 24.18.040(F), new development and major renovations within that overlay are subject to Urban Design Review by the city's Design Review Board and City Council, conducted under Chapter 24.11, and measured against the Design Guidelines for Properties in the Mixed Use Overlay Zone and the city's Urban Design Program Report.
The overlay's design and site plan requirements are not limited to brand-new construction: Section 24.18.010(A)(6) applies the overlay's requirements, including design review, to any remodeling or addition exceeding two thousand five hundred square feet, and to any change of occupancy affecting more than two thousand five hundred square feet within an existing structure. Section 24.18.010(A)(7) requires both Site Plan Review and Urban Design Review for all new development and major renovation within the zone. The overlay's other numeric standards work alongside the design mandate: building height in the MU Zone tops out at forty-six feet except by special permit under Section 24.02.050 findings, and residential density is capped at forty units per acre on sites larger than ten thousand square feet, or thirty units per acre on smaller sites.
Violations & Fines
Building new development or a major renovation in the Mixed Use Overlay Zone without completing the required Urban Design Review by the Design Review Board and City Council is a zoning violation the Community Development Department can enforce by withholding building permits until the project is redesigned to conform to the Design Guidelines for Properties in the Mixed Use Overlay Zone. A remodel or change of occupancy exceeding the two-thousand-five-hundred-square-foot threshold that proceeds without the overlay's Site Plan Review is likewise subject to a stop-work order until the review is completed.
