Hydrology & Drainage Studies
Manage water before it manages you.
Studies that assess water flow and design drainage solutions to prevent erosion and manage stormwater — required on many grading and development permits.
What's included
- —Stormwater & runoff analysis
- —Erosion control
- —Drainage design
- —Permit documentation
Approved plans, engineered in-house
Real plan sets we drew, stamped, and got approved through San Diego–area jurisdictions — not stock images.

Common questions
- When do I need a hydrology or drainage study?
- Typically when a project changes how water moves across the site — grading, a new structure, or development on a sloped or runoff-sensitive lot. Many San Diego grading and building permits require drainage documentation, and we'll tell you up front whether yours does.
- What does a drainage study actually do?
- It analyzes how stormwater flows across and off your property, then designs solutions — grading, swales, or drains — to prevent erosion and pooling and to satisfy permit requirements. The goal is managing water before it manages your foundation or your neighbor's lot.
