City of Orange Multiple HSIP Signal Improvement Projects

KOA has prepared complete PS&E plans for several intersections within the City of Orange funded by the federal Highway Safety Improvement Program (HSIP) grant funds. These signal modifications were primarily to improve safety of the intersections by implementing protected/protected-permissive left turn phasing. This project allows the City the opportunity to address additional deficiencies with gutter, drainage, and ADA compliant curb ramps. The work includes complete PS&E for traffic signal improvement plans, signing and striping plans, civil plans, surveying services, utility coordination, and coordination with SCE for new electrical service connection.
