Both distances run in a straight line between property boundaries.
Overconcentration. To avoid overconcentration, a Cannabis Retail use shall not be established within 600 feet of any other Cannabis Retail use established within and permitted by the City of Santa Rosa. The Department shall establish evaluation criteria and selection procedures as necessary to avoid overconcentration of Cannabis Retail uses where competing applications are submitted within a 600-foot radius of each other. ... Setback to schools. Cannabis Retail shall be subject to a 600-foot minimum setback from any K-12 "school," as defined by the Health and Safety Code Section 11362.768.
Full Breakdown
080(D) gives Cannabis Retail two separate location buffers. The overconcentration rule bars a new Cannabis Retail use from locating within 600 feet of any other Cannabis Retail use already established and permitted by the City, and the Department is directed to set evaluation criteria and selection procedures for competing applications that land within 600 feet of each other. 768, measured in a straight line from the boundary of the retail parcel to the closest boundary of the school parcel. If a school opens within that 600-foot radius after a dispensary already holds its Conditional Use Permit, the dispensary does not have to close: the code makes it legal nonconforming and protects it under Chapter 20-61 (Non-Conforming Uses, Structures and Parcels).
080(F)(10) bars a Cannabis Retail facility from advertising or marketing cannabis products on a sign within 1,000 feet of a day care center, K-12 school, playground, or youth center, which is a sign-content rule layered on top of, not a substitute for, the 600-foot siting buffers.
Violations & Fines
A Conditional Use Permit application that lands inside either 600-foot buffer is subject to the Department's evaluation and selection procedures for competing sites, and a dispensary sited in violation of the school or overconcentration buffer can have its permit denied or, if already issued in error, modified or revoked under Section 20-46.100 for violating a City Code provision or permit condition.
