Site Survey
Document existing grades, utilities, drainage patterns, impermeable surfaces, and sensitive features; baseline data used to calibrate models and identify constraints that affect design and permitting.
A Project Management Drainage Study clarifies responsibilities, documents regulatory compliance, and reduces construction delays by identifying drainage constraints early. It provides engineers and permitting officials with the data needed to approve designs and helps owners budget for drainage infrastructure and long‑term maintenance.
Typical users include project managers, civil engineers, municipal reviewers, and environmental consultants involved in site development and stormwater management.
Use the study to speed approvals, reduce site risk, and inform procurement and maintenance planning.
Document existing grades, utilities, drainage patterns, impermeable surfaces, and sensitive features; baseline data used to calibrate models and identify constraints that affect design and permitting.
Calculate design storm runoff using local rainfall data, CN or TR-55 parameters, and time of concentration to size conveyance and storage elements for regulatory storms.
Characterize soil hydraulic properties and infiltration rates with on-site tests or mapped data to determine feasibility of infiltration-based controls and groundwater impact during and after construction.
Specify channel, pipe, swale, and inlet layouts with slope, capacity, material, and erosion protection details aligned with local standards and constructability considerations and maintenance access requirements.
Design detention, retention, and treatment practices sized for peak flows and pollutant removal targets; include outlet controls, bypass provisions, inspection and sediment management details.
Provide routine and long-term maintenance tasks, inspection frequency, responsible parties, estimated costs, and replacement timelines to preserve drainage function and permit compliance, including sediment removal, vegetation control, and inlet cleaning schedules.
| Field | Configuration |
|---|---|
| Upload Documents | PDF, DOCX; include maps and test reports. |

Select delivery methods and integrations to match reviewer expectations and IT policies, including cloud storage and SSO.
Submit complete report and attachments to permitting agency.
Often 30–60 days; depends on backlog.
Resubmit revisions within requested timeframe, typically 15–30 days.
Permit issued after clearance of technical comments.
Schedule inspections during earthwork and final restoration.
A municipal redevelopment required revised drainage modeling after a major subdivision altered runoff; the project team commissioned a targeted drainage study.
A retail center's grading plan lacked documented infiltration testing; the drainage study provided soil data and a treatment train to meet nutrient loading limits.
