When approved or required by the city manager, a developer shall make a monetary payment or some other form of valuable consideration in lieu of building a detention facility. The city manager shall make the determination of whether fee in lieu of detention will be allowed or required based upon capacity of the receiving stormwater drainage system and whether regional detention facilities are either proposed or in place. The developer shall provide the city manager calculations of the number of square feet of increased impervious area and the city manager shall prepare a bill for payment of fee in lieu of detention. The rate for the fee in lieu of detention shall be thirty cents ($0.30) per impervious square foot. The fee shall be paid at the time the final plat is released for residential developments. The fee shall be paid prior to issuance of any building permit for nonresidential developments. When these fees are collected, they shall be deposited into a stormwater capital improvements fund, which will be used for future or ongoing stormwater improvement and regional detention projects.
