Slope Analysis Map

Slope conditions directly impact what can be built on hillside and coastal properties — especially in California where cities and agencies have strict hillside regulations. CA5 performs slope analysis surveys to measure and categorize terrain, calculate slope bands, and provide the data required for code compliance, entitlement, and design.

We collect high-accuracy topographic and geospatial data and apply local jurisdiction hillside ordinances to determine slope area allocations and regulatory slope percentages. This information is used by architects, civil engineers, and planners to calculate allowable floor area ratios, establish buildable envelope locations, manage grading requirements, and evaluate feasibility of proposed improvements.

Accurate slope information early in the design process helps avoid costly redesigns and ensures that the design team is working within real physical and regulatory constraints. CA5’s slope analysis is trusted by design professionals throughout Southern California.
