S. Roof drain leaders. All newly constructed and reconstructed buildings must route roof drain leaders to pervious areas (not natural wetlands) where the runoff can infiltrate. The discharge rate shall be controlled so that no erosion occurs in the pervious areas. T. Follow-up inspections will be performed by the city on a regular basis and after a 0.5 inch rain event to ensure that erosion and sediment control measures are properly installed and maintained. In all cases the inspectors will attempt to work with the developer and/or builder to maintain proper erosion and sediment control at all sites. 1.) The city has established a system of notices for enforcing erosion control. 2.) In the event these notices are ignored, construction stop orders may be issued by the city, until erosion and sediment control measures meet specifications. A second erosion and sediment control/grading inspection must then be scheduled and passed before the final inspection will be done. U. Removal of more than one (1) acre of topsoil shall not be done, unless written permission is given by the city engineer. Excessive removal of topsoil can cause significant soil erosion problems. V. Inspection and maintenance. All storm water pollution control management facilities must be designed to minimize the need of maintenance, to provide easy vehicle and personnel access for maintenance purposes and be structurally sound. These facilities must have a plan of operation and maintenance that ensures continued effective removal of the pollutants carried in storm water runoff. The city or its designated representative shall inspect all storm water management facilities during construction, during the first year of operation and at least once every five (5) years thereafter. The city will keep all inspection records on file for a period of six (6) years. It shall be the responsibility of the applicant to obtain any necessary easements or other property interests to allow access to the storm water management facilities for inspection and maintenance purpose. 9.27.11 Permanent Storm Water Pollution Controls. Subdivision 1. The applicant shall install, construct, or pay the city fees for all storm water management facilities necessary to manage increased runoff, so that the discharge rates from storm water treatment basins for the predevelopment ten (10) year, and one hundred (100) year peak storm discharge rates are not increased. These predevelopment rates shall be based on the last ten (10) years of how that land was used. Accelerated channel erosion must not occur as a result of the proposed land disturbing or development activity. An applicant may also make an in-kind or a monetary contribution to the development and maintenance of Page 13 of21 November 8, 2006 Storm Water Pollution Control Ordinance
