Since 1980, Urban Systems has been successfully designing traffic signals, roundabouts, striping plans, and detour plans, as well as extensively conducting impact and mitigation analysis for major public works and development projects. Detailed construction phasing, traffic control and construction detour plans for mass grading, sewer lines, roadway, freeway interchange modifications, and staged construction of facilities are regularly prepared at Urban Systems. Our clients have been both public agencies and private developers. More than eight hundred sets of construction plans, estimates, and bid packages have been prepared for acceptance in various jurisdictions. Our staff has been designing and/or reviewing these types of plans for over fifty years. We have on staff several licensed Civil Engineers and Traffic Engineers who are the engineer of work for the specific projects requiring this expertise. Two members of our staff have been involved in full-time municipal engineering for local jurisdictions, with extensive experience with the City of San Diego. Our staff has had extensive operations experience which brings to our firm functional design experience from qualified engineers able to understand the client's perspective.
