​Baldwin Park Operable Unit - San Gabriel Valley, California

~ Superfund cleanup

We've all become aware of the vital importance of a clean reliable source of drinking water in our lives. Bell Land Surveying played an important role in this EPA mediated groundwater cleanup of the San Gabriel Valley. We provided boundary surveying, topographic mapping, subdivision mapping, street vacations, easement preparation and construction staking for three major water treatment facilities in Irwindale, Baldwin Park, and the City of Industry.

​Camp Stevens - San Diego County, California

Giving back to the community is very important to Bell Land Surveying. A wildfire swept through Camp Stevens in the mountains high above San Diego, burning half the camp. We've donated extensive surveying and mapping services of the camp facilities over the past few years, including aerial mapping, ground topography and tree surveys.

Camp Stevens does a wonderful job of developing our next generation of leaders by providing meaningful hands-on outdoor experiences for hundreds of children. The camp encourages stewardship and a deep awareness of the environment. We're proud to support Camp Stevens as it rebuilds.

Coastal Cactus Wren Conservation Project - Orange County, CA

We provide pro bono biological mapping and surveying to several Orange County environmental conservation organizations, the Nature Conservancy, The National Audubon Society, and the Irvine Ranch Conservancy. By sharing our expertise, Bell Land Surveying helps conserve and restore natural ecosystems.

The coastal Cactus Wren, a California Bird Species of Special Concern, is an indicator species for the conservation of coastal sage scrub, a plant community that has fragmented and decreased substantially from its historic coverage as a result of urban and agricultural development.

​YMCA Camp Whittle - San Bernardino County, California

Nestled on 125 acres in the San Bernardino Mountains, The YMCA's Camp Whittle provides a rich experience for thousands of Southern California kids.

We've provided boundary property line studies, National Forest boundary posting, topographic mapping, aerial photography, utility mapping and wetlands delineation for this flagship camp facility. We're pleased to help the YMCA "build strong kids, strong families, strong communities."

​Infrastructure Rehabilitation Projects - Southern California

Bell Land Surveying has provided land survey control on over 245 projects in Los Angeles, Riverside, San Bernardino and Orange County in the past three decades.

We've established centerline control, staked line and grade for construction, perpetuated survey monuments, measured cross-sections, conducted as-built surveys, and run heading checks.

​Construction projects include curb & gutter, street reconstruction, asphalt paving, pavement overlays, storm drains, sanitary sewers, water lines, sidewalks, and ADA ramps for the disabled. Some representative projects:
• Brea
• Whittier
• Buena Park
• Orange
• Costa Mesa
• La Habra
• Pasadena
