In order to utilize offset fees, the proposed new development <br /> subject to the nutrient load standards must attain nitrogen and phosphorus <br /> loading rate reductions on-site that meet the following criteria prior to using an <br /> offsite offset measure: <br /> (a) Falls Lake Watershed <br /> (i) 30% or more reduction in both nitrogen and phosphorus loading <br /> from the untreated conditions for any single-family, detached and <br /> duplex residential development disturbing one half acre but less <br /> than one acre; <br /> (ii) 50% or more reduction in both nitrogen and phosphorus loading <br /> from the untreated conditions for any single-family, detached and <br /> duplex residential development disturbing more than one acre; <br /> (iii) 30% or more reduction in both nitrogen and phosphorus loading <br /> from the untreated condition for other development, including <br /> multi-family residential, commercial and industrial development <br /> disturbing 12,000 square feet but less than one acre; <br /> (iv) 50% or more reduction in both nitrogen and phosphorus loading <br /> from the untreated condition for other development, including <br /> multi-family residential, commercial and industrial development <br /> disturbing more than one acre; <br /> (v) 30% or more reduction in both nitrogen and phosphorus loading <br /> from the untreated condition for proposed redevelopment <br /> activities in a designated downtown area that would replace or <br /> expand structures or improvements that existed as of December <br /> 2006. <br /> (2) Offset fees may be paid to the North Carolina Division of Mitigation Services <br /> (DMS 176 approved private mitigation bank, or other mitigation option as <br /> approved by the NCDEQ and Orange County. It is the policy of the177 NCDEQ <br /> and Orange County, as well as a requirement in certain watersheds, that offset <br /> payment funds be utilized where they are generated to the maximum extent <br /> possible. <br /> (3) Offset payment fees and calculation methods are determined by the NCDEQ as <br /> approved by the North Carolina Environmental Management Commission (EMC). <br /> The total amount of offset payment will be determined based on current NCDEQ <br /> policy and regulation on a case by case basis. <br /> (E) Permanent Nutrient Export Reduction ®nakiga4uo- t_p_r 178 <br /> 116 Text correction—added "(DMS)'. <br /> 17 Text correction—added "the". <br /> 178 "Best Management Practices"deleted so as to avoid confusion with superseded BMP terminology. <br /> Orange County, North Carolina— Unified Development Ordinance Page 6-102 <br />
