S.D. Codified Laws § 46A-10B-21
In the case of a lot or parcel of land upon which a building has not been erected, the governing body may require the payment of a stormwater basin development fee as a condition for the development of the property. The stormwater basin development fee is payable prior to the approval of the final plat of the subdivision or, in the case of unplatted property, prior to the issuance of a building permit. The fee is intended to pay for the design, right-of-way acquisition, and construction or reconstruction of stormwater facilities needed to protect the health, safety, and welfare of the inhabitants of the various basins. The stormwater basin development fee shall be paid by the developer and shall be based upon the cost of necessary facilities to be constructed, the area of each parcel of land, the runoff characteristics of the parcel and the amount of on-site stormwater detention, if any, provided. The governing body shall determine the rates that apply to each parcel of land within the guidelines established by ordinance pursuant to § 46A-10B-20, but the stormwater basin development fee for any parcel of land within the district may be no less than one hundred dollars and no more than eight hundred dollars per subdivided lot. The eight hundred dollar limit does not apply to nonresidential developments.
