Grading, Stormwater (NPDES) & Building Permits

Welcome

Hello, and welcome. This is Super Structures General Contractors — a national general contractor headquartered in Powhatan, Virginia — here to help you and your clients build something that lasts. We're glad you're with us, and we look forward to connecting with you.

Here's one that matters more than its name lets on — Grading, Stormwater (NPDES) & Building Permits. Bottom line — write this one down: Map the permit sequence into your schedule; permitting delays slip projects. Nail it, and it pays you back on every job you ever run.

Approvals get you the right to build; permits let you actually start.

Common permits

• Grading / land-disturbance permit — to move dirt; requires an approved grading and erosion-control plan.
• Stormwater / NPDES permit — for projects disturbing (typically) 1+ acre, a federal Clean Water Act program (administered by states) requiring a Stormwater Pollution Prevention Plan (SWPPP) and erosion/sediment controls.
• Utility / right-of-way permits — to connect water, sewer, and to work in public streets.
• Building permit — to construct vertical improvements, issued after construction-document review.

Sequencing

Permits come in an order: you usually can't pull a building permit until the site/civil work is approved and sometimes underway. Map the permit sequence into your schedule — permitting delays are one of the most common reasons projects slip.

Going Deeper (Intermediate)

Beyond zoning you need engineering and construction permits: a grading permit (earthwork), a stormwater/drainage permit, building permits, and utility/encroachment permits — each with its own agency review.

Advanced / Pro-Level

The permit critical path:

• Sequence: entitlement → improvement (civil) plans → grading + SWPPP → building permits.
• NPDES/SWPPP is required for sites ≥ 1 acre of disturbance (EPA/state).
• The grading permit ties to approved civil plans; building permits follow site work.
• Impact/development fees are typically due at permit issuance (and can be large).
• Plan-check cycles take months and run in series — agency review time is one of the biggest schedule risks a developer carries.

Practice Challenge

A developer budgets 4 weeks for permits and is shocked when grading and building plan-check take 6 months. What did they misjudge? (Answer: the agency plan-review critical path — entitlement, civil/grading, SWPPP, and building permits review in sequence over months; permit timelines (and the carrying cost of that time) are a major schedule risk that must be realistically built into the pro forma.)

In Practice

A developer can't pull a building permit because the grading and stormwater permits aren't done — the sequence stops them cold. Map the permit order into the schedule.

Common Mistakes to Avoid

• Not sequencing permits correctly
• Underestimating permitting time
• Disturbing land without the required permits

Takeaway: Map the permit sequence into your schedule; permitting delays slip projects.
