ORD NO 11-2004 CITY OF VAN BUREN, ARKANSAS 0 ORDINANCE NO. I i -2004 AN ORDINANCE ADOPTING A GRADING AND EROSION CONTROL ORDINANCE. WHEREAS, The City of Van Buren does not currently have any Ordinance regulating grading and erosion as a result of construction; and WHEREAS, After a public hearing and public comment, the Planning Commission has recommended that the City adopt an ordinance regulating grading and erosion. NOW, THEREFORE, BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF VAN BUREN, ARKANSAS: SECTION 1: Introduction/ Purpose. During the construction process, drainage patterns are often altered and soil is highly vulnerable to erosion by wind and water. Improper grading can concentrate or redirect drainage Clow negatively impacting neighborhoods and increase soil erosion. Eroded soil endangers water resources by reducing water quality and causing the siltation of aquatic habitat for fish and other desirable species. Eroded soil also necessitates repair and cleaning of sewers, ditches, streams and ponds. In addition, clearing and grading during construction cause the Toss of native vegetation necessary for terrestrial and aquatic habitat. As a result, the purpose of this local regulation is to safeguard persons, protect property, and prevent damage to the environment within the City of Van Buren. This ordinance will also promote the public welfare by guiding, regulating, and controlling the design, construction, use, and maintenance of any development or other activity that disturbs or breaks the topsoil, results in the movement of earth or impacts drainage flow on land in City of Van Buren. SECTION 2: Definitions. Building Department The Building Department of the City of Van Buren or its designated representative. Clearing Any activity that removes the vegetative surface cover. Drainage Way Any channel that conveys surface runoff throughout the site. Erosion Control A measure that prevents erosion. Erosion and A set of plans indicating the specific measures and sequencing to Sediment be used to control sediment and erosion on a development site during Control Plan and after construction. Grading Excavation or fill of material, including the resulting conditions thereof. Perimeter Control A barrier that prevents sediment from leaving a site by filtering sediment laden runoff or diverting it to a sediment trap or basin. Phasing Clearing a parcel of land in distinct phases, with the stabilization of each phase completed before the clearing of the next. Sediment Control Measures that prevent eroded sediment from leaving the site. Site A parcel of land or a contiguous combination thereof, where grading work is performed as a single unified operation. Site Development A permit issued by the municipality for the construction or alteration of Permit ground improvements and structures for the control of erosion, runoff and grading. Stabilization The use of practices that prevent exposed soil from eroding. Start of Construction The first land- disturbing activity associated with a development, including land preparation such as clearing, grading, and filling; installation of streets and walkways; excavation for basements, footings, piers, or foundations; erection of temporary forms; and installation of accessory buildings such as garages. Watercourse Any body of water, including, but not limited to lakes, ponds, rivers, streams, and bodies of water delineated by the City of Van Buren. Waterway A channel that directs surface runoff to a watercourse or to the public storm drain. SECTION 3: Permits. A) No person shall conduct clearing or grading activity that would require the clearing of one (1) acre or more without first obtaining a site development permit from the City of Van Buren.

A) The Erosion and Sediment Control Plan shall include the following: 1) A site map at a scale no smaller than 1"=100' showing erosion and sediment control proposed for the site. 2) A se quence of dealing and grading activities anticipated for construction of the development site. Sequencing shall include the anticipated dates for the start of construction, installation of temporary erosion and sediment control measures, and establishment of permanent vegetation. 3) Erosion and sediment control measures necessary to meet the objectives of this ordinance that will remain installed and functioning throughout all phases of 3) Special techniques that meet the BMP on steep slopes or in drainage ways shall be used to ensure stabilization. 4) Soil stockpiles must be stabilized when inactive for periods longer than 2 weeks. 5) The entire site must be stabilized by seeding and mulching when site grading is complete. The Building Department may require stabilization of any part of the site that will remain inactive for longer than 2 weeks or when an erosion problem is identified. 6) Techniques that divert upland runoff past disturbed slopes shall be employed. F) Sediment controls requirements shall include: 1) Settling basins, sediment traps, and perimeter controls. 2) Settling basins that are designed in a manner that allows adaptation to provide long -term storm water management, if required by Building Department. 3) Protection for adjacent properties by the use of a vegetated buffer strip in combination with perimeter controls.
