FAQ
What info do I need to provide to start?
: Please share your site plan (CAD or PDF), contours/spot elevations, project location, and any specific local municipality drainage guidelines or storm return period requirements
Will these calculations be accepted for a permit?
Yes. All calculations, pipe sizing schedules, and hydraulic reports are prepared according to standard municipal engineering manuals and recognized hydrologic/hydraulic design criteria.
What software do you use for storm sewer modeling?
I utilize industry-standard tools including AutoCAD Civil 3D, EPA SWMM, Storm and Sanitary Analysis (SSA), and custom engineering hydrologic calculation sheets.
Can you design detention ponds along with pipe sizing?
Absolutely. I can size detention/retention facilities, inlet catch basins, and outfalls as part of a comprehensive stormwater management package. Contact me for a custom scope.
