Stormwater and drainage design

We design the storm drainage, detention and erosion control that move water safely off and around your site.

Overview

What this covers.

Water shapes every site. We design the drainage, detention and erosion control that keep a project compliant and a site dry.

Good drainage goes unnoticed because it works.

Scope

Scope of work.

Storm sewer design

Inlets, pipes and outfalls sized for the design storm.

Detention and retention

Ponds and underground systems sized to your site requirements.

Grading for drainage

Surfaces that carry water where it needs to go.

Hydrology and hydraulics

The calculations behind the design and the review.

Erosion and sediment control

Plans and details for each phase of construction.

Drainage reports

Clear narratives and calculations for reviewers.

FAQ

Common questions.

What software do you use?

Civil 3D for surfaces and pipe networks, with the calculations laid out in a clear report.

Do you need survey and soils information?

Yes. We build from the survey and reports you send, and we flag any gaps early.

Do you prepare drainage reports?

Yes. We write the narrative and the calculations that support the plans.

Can you work with local requirements?

We design to the requirements that apply to your site. Tell us the jurisdiction when we scope the work.

How do you quote this work?

By site size and scope. Tell us about the site and we will put a quote together.

Have a project on the board?

Send us the scope and we will come back with a quote, or start with a free pilot package.
