When submitting plans to Office of Central Inspection (OCI), Stormwater Management requires a separate stormwater site grading plan that includes the impervious area calculations, property address, and other additional information useful to stormwater staff. Each stormwater site grading plan submittal shall include the following:

1. Delineation of project limits
2. Square footage measurements – Pervious and Impervious Areas
3. Project address and/or Legal description of property
4. Cross hatching of impervious area – The cross hatched area will include all impervious areas within the project’s property limits including the drive approaches from city street right-of-way. Public streets and sidewalks in the city right-of-way shall not be included in impervious area calculations.
5. Building permit number (if known)

Per Chapter 16.30.010 (p) of the City Code, “Impervious area” is defined as the number of square feet of hard surface areas which either prevent or retard the entry of water into soil mantle, as it entered under natural conditions as undisturbed property, and/or causes water to run off the surface in greater quantities or at an increased rate of flow from that present under natural conditions as undisturbed property, including, but not limited to, roofs, roof extensions, patios, porches, driveways, sidewalks, pavement, athletic courts, and compacted dirt or graveled areas.

The stormwater site grading plan shall be submitted to Stormwater Management electronically in PDF format or as a hard copy with the above referenced information included. The Figure below is an example of the information we are requiring with exception to the project’s impervious area.

The plans submitted in PDF format shall be emailed to Renee Batchman, Administrative Aide II for Stormwater Management at rbatchman@wichita.gov. The file size cannot exceed 5MB or the email will not be received. The preferred submittal method is electronic. However, a hard copy of the stormwater site grading plan may be submitted to Storm Water Management, Attention: Renee Batchman, 455 N. Main, City Hall 8th Floor , Wichita, KS 67202. For additional examples of the stormwater site grading plan, see the one developed for Siena Plaza.
