Specializing in completing SWMM stormwater infra structure models. We've built entire cities and river basin systems for review, analysis, & modeling to determine your best infrastructure solution. Currently, our local Hillsborough County SWMM program has FEMA approval for Flood Plain delineation and revisions.

Top 10 Stormwater Modelling Tips

  1. Get County or Water Management District topographic maps on disk.
  2. If they Have topo on disk, check for roads, parcels and soils also.
  3. Find other large studies completed in your basin study area, check:
    • Municipal Engineering Department
    • Transportation Departments
    • Economic Planning Dept.
    • Regional resources
    • FEMA and USGS studies
  4. Find all the pipes and system connections for flow, check if municipalities have any infrastructure atlases, flooding or repair records.
  5. VISIT THE SITE. Often interconnections can only be found onsite. They may have changed too, residents often board up weirs to make their ponds larger.
  6. Compile existing site infrastructure data to develop your basins data.
  7. Layout system and define survey and data holes where additional information is required.
  8. Delineate basin areas. Calculate Time of Concentrations.
  9. If TOC's or basins have a great variation in size combine or break them up to create a 10-20% variation.

This can include data compilation for:

  • Conditional Letters of Map Amendment (CLOMAs)
  • Conditional Letters of Map Revision - based on Fill (CLOMR-Fs)
  • Letters of Map Revision - based on Fill (LOMR-Fs) requests
  • certain Conditional Letter of Map Revision (CLOMR)
  • Letter of Map Revision (LOMR) requests
  • Municipal Developments of Regional Impact (DRI)
