The City of Long Beach was required by court ruling to map, design, and reconstruct approximately 1000 Curb Ramps that were non-compliant with the current ADA standards. Cannon was contracted by HDR Engineering to provide detailed topography and monument preservation surveys as well as assisting with project coordination and scheduling. Cannon’s team provided a field survey of existing surface culture and survey monuments as well as drafting of ramp areas with Digital Terrain Model (DTM) and site photos included. Cannon’s topographic survey services for ramps establish the basis for the final design plans.
