BKF provided civil engineering services for Delta Coves, a 310‑acre master‑planned luxury waterfront community located in the Sacramento–San Joaquin Delta. Because the community required reliable drinking‑water and fire‑suppression infrastructure, BKF designed innovative utility solutions capable of crossing sloughs and waterways to connect Bethel Island to the mainland.
As part of the project, BKF designed 900 linear feet of 20‑inch welded steel water pipe along the Bethel Island Bridge, 6,500 linear feet of 18‑inch ductile iron pipe on Bethel Island Road, and 1,100 linear feet of 12‑inch fused PVC installed inside 16‑inch fused PVC and 30‑inch steel casing beneath the Delta Coves breach using horizontal directional drilling. BKF also prepared complete plans, specifications, and cost estimates, and secured all required permits to support construction of these complex utility crossings.
