Stormwater Engineering

Stormwater design considers drainage areas, site surfaces and the receiving system. The work may involve calculations and proposed improvements coordinated with the site layout and the authority reviewing it.

An engineer may be needed when development changes runoff, an existing system needs modification or a reviewer requests a drainage analysis.

Confirm the engineering scope with the professional you engage and any permit requirements with the local building department.

Topics that may be relevant to the review: French drain, catch basin, culvert, detention pond, retention pond and storm inlet.

The engineer can review existing conditions, evaluate the proposed changes and prepare the calculations or design details included in the agreed scope.

• Evaluating runoff from a proposed development
• Modifying an existing water-management system

These documents may be relevant to the work. Agree on the deliverables with your engineer and confirm any submission requirements with the reviewing authority.

• drainage calculations

Start with a short description. These details can help define the scope, but you do not need everything ready to request a quote.

• The project city or county, and the property address if known
• What you want to build, change or repair
• How the space or site is used now and what you plan to change
• Whether you have drawings or photos to share during follow-up
• The status of any permit application and comments received
• Your target dates or other scheduling constraints

• Site Plans
• Grading & Drainage
• Drainage Corrections
