WHEREAS, in 2009 the City of Fayetteville and the Beaver Water District entered into an agreement to have Geosyntec Consultants produce a Nutrient Reduction Plan, and WHEREAS, one of the recommendations of the Nutrient Reduction Plan was for the City of Fayetteville to develop a Low Impact Development ordinance to reduce non-point source water pollution from entering the Beaver Lake watershed, and WHEREAS, the Green Infrastructure group from the Fayetteville Forward Economic Accountability Summit has worked to promote the adoption of environmentally sensitive design solutions, such as Low Impact Development, and WHEREAS, a member of the City Council has worked to advance the adoption of Low Impact Development principles and practices as an elected official and in her professional capacity,and WHEREAS, the development community is beginning to acknowledge and embrace the advantages of utilizing Low Impact Development systems and solutions to better manage stormwater runoff, and WHEREAS, the City of Fayetteville recognizes the environmental benefit of Low Impact Development practices for the greater good of the region's water resources. NOW,THEREFORE,BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF FAYETTEVILLE,ARKANSAS: Section 1.That the City Council of the City of Fayetteville, Arkansas hereby amends the Unified Development Code by adding Chapter 179: Low Impact Development as shown in Exhibit"A" attached hereto and made a part hereof.
