Critical Area Maps Sources

Printer-friendly versionPDF version

The approximate location and extent of critical areas and lands within the city planning area are provided from various agency map sources. These maps are based on the best available information and are intended to be used as a general guide for the assistance of property owners and as information for the public. Boundaries are generalized; field investigation and analysis by a qualified expert may be required to confirm the existence of a critical area. The city will update information and resource material as it becomes available and feasible.
