A submittable TDEC CN-1249 (Rev. 07-24) Stormwater Pollution Prevention Plan for at-grade single-family lots - pre-filled from a few quick questions.
① Eligibility
Does this lot require mass grading? *
CN-1249 is only for at-grade lots. It is NOT valid if mass grading (significant cut/fill or earthwork beyond foundations, the building pad, and utility trenching) is required.
This lot isn't eligible for the CN-1249 homebuilder SWPPP. Mass grading requires a full contractor SWPPP (engineered or non-engineered).

Is this lot inside a development, or standalone? *
Heads up: a standalone single lot usually only needs permit coverage if it disturbs 1 acre or more, or is part of a larger common plan of development totaling an acre or more. If your lot is under an acre and not part of a larger plan, you may not need a SWPPP at all. You can still generate one (some lenders or local programs ask for it), but verify with TDEC before relying on it.
