ADA Ramp Surveys in El Cerrito, CA

El Cerrito adopted an ADA transition plan in 2009 covering city buildings, parks, and major pedestrian routes in the public right of way, and it has kept moving on it: the city runs recurring access modification projects that replace sidewalk, curb, gutter, and drainage and construct curb ramps at prioritized locations, with an ADA advisory group weighing in on which barrier types come first. That means a fairly constant supply of ramp construction and closeout verification in a city that is only a few square miles.

Geography makes the work harder than the size suggests. El Cerrito rises from the San Pablo Avenue flats to steep hillside streets, and on those hillside returns the running slope, flare slopes, and the flat landing all compete for the same few feet of curb. Along the San Pablo corridor the problem inverts: the grade is manageable, but the sidewalk is crowded with transit stops, driveways serving older commercial frontage, and infill construction that keeps changing the route. The high-traffic crossings feeding the El Cerrito Plaza and del Norte BART stations concentrate pedestrian demand on exactly the corners where the geometry is tightest.

We scan or shoot the ramp, landing, gutter pan, and adjoining sidewalk and compute running slope, cross slope, level changes, and detectable warning placement from the modeled surface, tied to survey control. Private-property work covers entrance ramps and thresholds, exterior paths of travel, and accessible stalls and access aisles, where the flatness limit applies in every direction. You receive per-ramp slope exhibits, spot elevations on a CAD plan, and the registered point cloud on request. We document conditions; the CASp inspector or architect determines compliance.
