FAQ
Can you calculate stormwater runoff?
Yes. I can perform runoff calculations based on the project information, rainfall/design criteria, drainage areas, and methodology required for the project.
Can you prepare a hydrology report?
Yes. I can prepare hydrology documentation based on the agreed project scope, available site information, design criteria, and applicable requirements.
Can you analyze stormwater pipe networks?
Yes. Pipe network hydraulic analysis can include flow rates, pipe capacity, velocities, slopes, and related hydraulic parameters based on the available project data.
Can you create a stormwater drainage plan?
Yes. I can prepare drainage layouts showing relevant drainage areas, flow paths, inlets, pipes, structures, and proposed stormwater systems according to the agreed scope.
Can you work with my existing civil plans?
Yes. You can provide existing civil plans, topographic surveys, CAD files, drainage plans, architectural plans, or other relevant project documents.
Can you design detention or retention systems?
Potentially, depending on the project scope and applicable requirements. Please send the project information and jurisdictional criteria before ordering so the required analysis can be reviewed.
Will the report or design be approved by the city?
Final approval depends on the applicable authority and its review process. Approval cannot be guaranteed. Professional certification or stamping is provided only where legally applicable and specifically included in the agreed scope.
