Claremont Project Planning and Engineering

Challenge: The City of Claremont is a suburban city on the eastern edge of Los Angeles County, California, and is known for its tree-lined streets with numerous historic buildings. The City desired on-call engineering, on-call plan review, project management, and roadway design.

Solution: HR Green has provided the  design services and prepared improvement plans for several projects to better serve pedestrians and bicyclists and to improve the overall driveability of roadways. Since working with the City, HR Green has provided Claremont project planning for several projects, including:

Towne Avenue Street Improvements

Towne Avenue is a main corridor in Claremont and it is only one of two roads in Claremont with access to the 210 freeway, making it one of the heaviest-used routes in Claremont. HR Green provided design services for improvements to Towne Avenue that incorporated “complete streets.” This design included the addition of new landscaped medians down the center of Towne Avenue and tree wells along the sidewalks on both sides of the street.

New bulb-outs were also incorporated into the design to slow down traffic and allow for a more comfortable and safer path for pedestrians when crossing the street. New Class IV protected bike lanes and bike boxes at the intersections were designed to increase visibility and better serve bicyclists while improving the drivability of the road for motorists. Driving lanes and bike paths have been designed to be separated by small, landscaped medians reducing the stress of both bicyclists and motorists.

Traffic signal enhancements were also part of the project. Such improvements included upgraded signal lights, Intelligent Accessible Pedestrian Systems (APS), and new video detection. Other features and amenities included pavement rehabilitation and landscape and hardscape upgrades. Such features included sidewalk and driveway replacement and new ADA ramps to replace existing ramps. HR Green also designed “green street” components, incorporating Modular Wetland devices at existing catch basins and infiltration trenches within the center medians when possible.

Mt. Baldy Road Pavement Rehabilitation

As part of Claremont’s project planning on-call services ,  HR Green prepared improvement plans for Mt. Baldy Road between North Mills Avenue and Grand Avenue with plan view-only GIS-based plans. HR Green prepared construction bid drawings for the cold mill and overlay, re-striping drawings, technical specifications, and an engineer’s estimate of probable construction costs. The GIS-based approach saved the City roughly 15% in engineering fees.
