Project ID
Unique project name/number, project address, and parcel identifier to link the overview to permit records and construction documents.
A focused Site Drainage Overview saves review time, highlights regulatory issues early, and reduces rework by centralizing site facts and proposed controls in a single, consistent format. It supports permit approvals, contractor coordination, and long-term asset management while documenting assumptions and responsible parties.
The template is commonly completed by technical staff and reviewed by regulators and project stakeholders.
Use the template to establish shared expectations among designers, contractors, and local authorities before mobilization.
Unique project name/number, project address, and parcel identifier to link the overview to permit records and construction documents.
Brief description of topography, soil types, impervious area, drainage patterns, and floodplain or wetland indicators that affect runoff and control sizing.
List of proposed conveyance features and BMPs (inlets, swales, retention/detention basins, infiltration systems, riprap) with basic sizing assumptions and locations.
Key runoff calculations or references (design storm, CN or runoff coefficients, peak flow rates) that support the selection of control measures.
Names, roles, and contact information for the design engineer, property owner, and on-site contractor responsible for implementation and maintenance.
Permit numbers, required approvals, inspection triggers, and any special local conditions or sequencing constraints required by the authority having jurisdiction.

A site contractor uses the overview to align as-built drainage elements with maintenance obligations
Allow 3–7 business days for internal QA and engineering sign-off before submission.
Municipal intake processing ranges from 7–30 calendar days depending on backlog and complexity.
Plan reviewers commonly require 2–4 weeks for technical review of drainage calculations and attachments.
Expect 7–14 days to respond to reviewer comments to avoid permit expiration.
Allow 3–10 business days to schedule construction or post-installation inspections.
Compile site data, calculations, and exhibits for the overview.
Engineer and project manager sign off prior to external submission.
Upload the overview with the permit package to the authority portal.
Archive the signed overview with project records for the required retention period.
