The Boulders Subdivision

The Challenge

Located in steep, rocky terrain, this residential subdivision posed design and cost challenges from the start. When Land Pro Civil was brought in, initial plans prepared by a previous engineer featured overly wide roads, extensive detention infrastructure, and a water system layout that would have resulted in high construction costs. The developer needed a more efficient, cost-effective approach that could still meet county standards and maintain project momentum.

Land Pro Civil’s Targeted Solutions

• Reduced Road Width Based on County Code Review: We thoroughly reviewed applicable county roadway standards and found that the proposed road widths exceeded the minimum requirements. After confirming with county staff, we reduced the road widths accordingly. This not only saved on grading and paving costs but also reduced impervious surface area, directly contributing to reduced stormwater detention needs.

• Redesigned Drainage Strategy to Eliminate One Detention Pond: The original design included two large detention ponds with significant excavation, hauling, and retaining walls. By shifting to a decentralized strategy using individual lot detention where feasible, we were able to eliminate one of the ponds entirely. The remaining pond was resized, further reducing sitework and materials.

• Water System Redesign Including Pump Station and Tank: We led the coordination and oversight of the water system redesign, including the pump station and storage tank. Working closely with our subconsultant, we ensured the revised layout reduced material and installation costs while maintaining system efficiency, service reliability, and compliance with agency standards.

• Streamlined County Coordination: Our direct communication with county staff and code-backed design revisions led to a more efficient approval process, with fewer revisions and faster turnaround.

The Outcome

• Reduced Construction Costs: Narrower roads, fewer detention structures, and a simplified water system significantly lowered site development expenses.

• Lower Site Impact: Eliminating one detention pond and reducing road widths led to less grading and earthwork in the mountainous terrain.

• Accelerated Approvals: Collaborative engagement with county reviewers and clearly justified design changes helped streamline the review process.
