developer andJor builder to maintain proper erosion and sediment control at <br />all sites. <br /> <br />1 .) The city has established a system of notices for enforcing erosion <br /> control. <br />2.) In the event these notices are ignored, construction stop orders may be <br /> issued by the city, until erosion and sediment control measures meet <br /> specifications. A second erosion and sediment control/grading <br /> inspection must then be scheduled and passed before the final <br /> inspection will be done. <br /> <br />Removal of more than one (1) acre of topsoil shall not be done, unless <br />written permission is given by the city engineer. Excessive removal of <br />topsoil can cause significant soil erosion problems. <br /> <br />Inspection and maintenance. All storm water pollution control management <br />facilities must be designed to minimize the need of maintenance, to provide <br />easy vehicle and personnel access for maintenance purposes and be <br />structurally sound. These facilities must have a plan of operation and <br />maintenance that ensures continued effective removal of the pollutants <br />carried in storm water runoff. The city or its designated representative shall <br />inspect all storm water management facilities during construction, during the <br />first year of operation and at least once every five (5) years thereafter. The <br />city will keep all inspection records on file for a period of six (6) years. It <br />shall be the responsibility of the applicant to obtain any necessary easements <br />or other property interests to allow access to the storm water management <br />facilities for inspection and maintenance purpose. <br /> <br />9.27.11 Permanent Storm Water Pollution Controls. <br /> <br /> Subdivision 1. The applicant shall either install, construct, or pay the city fees for all <br />storm water management facilities necessary to manage increased runoff, so that the discharge <br />rates from storm water treatment basins so that the predevelopment ten (10) year, and one <br />hundred (100) year peak storm discharge rates are not increased. These predevelopment rates <br />shall be based on the last ten (10) years of how that land was used. Accelerated channel erosion <br />must not occur as a result of the proposed land disturbing or development activity. An applicant <br />may also make an in-kind or a monetary contribution to the development and maintenance of <br />community storm water management facilities designed to serve multiple land disturbing and <br />development activities undertaken by one or more persons, including the applicant. <br /> <br /> Subdivision 2. All calculations and information used in determining these peak storm <br />discharge rates shall be submitted along with the storm water pollution control plan. <br /> <br /> Subdivision 3. The applicant shall consider reducing the need for storm water <br />management facilities by incorporating the use of natural topography and land cover such as <br />natural swales and depressions as they exist before development to the degree that they can <br />accommodate the additional flow of treated (e.g, settled) water without compromising the <br /> <br />Draft StormWater Ordinance <br /> <br />Page 12 of 20 <br />January 20, 2006 <br /> 07 <br /> <br /> <br />
