About LC Site Management
Stormwater compliance and erosion control for Southern California builders.
LC Site Management handles stormwater compliance and erosion control for builders and developers in San Diego County and across Southern California. That means SWPPP development and QSD regulatory compliance, QSP inspections and monitoring, BMP installation and erosion control, and site management and drainage. We work on-site, including the inland desert areas.
The business is run by Arn Lundquist, a former construction supervisor and licensed general contractor with more than 25 years in the field. He knows how water moves across a site and what holds up when it rains, so the plans he writes and the BMPs he specifies pass inspection without slowing the build down.
What you get working with us:
Field-tested judgment. Plans and BMPs that work in real site conditions, not textbook checklists.
On-site responsiveness. Fast, hands-on service when the weather or an inspector won't wait.
Plain communication. Straight answers, no compliance jargon.
One accountable point of contact. We own the outcome from permit to close-out.
Whether you're breaking ground on a new development or keeping an active site inspection-ready, we keep you compliant and clear of regulatory trouble.
