Kansas City septic & civil engineering
Metro-edge acreage, stormwater detention, and rural septic outside the sewer line.
The growth ring around Kansas City is where city stormwater rules meet county septic rules. Acreage lots in Platte, Clay, Cass, and Johnson counties routinely need a detention or water-quality design and an onsite wastewater system on the same sheet set.
We handle grading and drainage plans, BMP sizing to APWA 5600 criteria, and septic design for parcels outside the sewer district — with a plan set formatted for the reviewing jurisdiction so the first submittal is the one that counts.
What we design in Kansas City
- Grading, drainage, and detention design to APWA 5600
- Onsite wastewater for acreage lots outside sewer service
- Erosion & sediment control plans and SWPPP support
- Site feasibility for infill and metro-edge subdivisions
- Driveway, culvert, and access permitting exhibits
Local code & permitting notes
- APWA Section 5600 stormwater criteria are the regional standard across most KC-area jurisdictions.
- County health departments permit onsite wastewater outside sewer districts; requirements differ by county.
- Land disturbance over 1 acre triggers an NPDES construction permit and SWPPP.
Code references are summaries for planning. Final requirements come from the permitting authority at the time of submittal.
