<br />CITY OF ROSEVILLE <br />ORDINANCE NO. 1239 <br /> <br />AN ORDINANCE AMENDING SECTION 1016.26 <br />OF THE ROSEVILLE CITY CODE CONCERNING <br />STORM WATER MANAGEMENT <br /> <br />THE CITY OF ROSEVILLE ORDAINS: <br /> <br />SECTION 1. Section 1016.26 of the Roseville City Code is amended to read as <br />follows: <br /> <br />The following general and specific standards shall apply to all developments <br />within the City. <br /> <br />A. General Standards: <br /> <br />1. Existing Natural Drainage ways: When possible, existing natural drainage <br />ways, and vegetated soil surfaces shall be used to convey, store, filter, and retain <br />storm water runoff before discharge to public waters. <br /> <br />2. Minimum Disturbance: Development shall be planned and conducted in a <br />manner that will minimize the extent of disturbed areas, runoff velocities, erosion <br />potential, and reduce and delay runoff volumes. Disturbed areas shall be <br />stabilized and protected as soon as possible and facilities or methods used to <br />retain sediment on the site. <br /> <br />3. Constructed Facilities: When development density, topographic features, <br />and soil and vegetation conditions are not sufficient to adequately handle storm <br />water runoff using natural features and vegetation, various types of constructed <br />facilities such as diversions, settling basins, skimming devices, dikes, waterways, <br />and ponds may be used. Preference shall be given to designs using surface <br />drainage, vegetation, and infiltration rather than buried pipes and man-made <br />materials and facilities. <br /> <br />B. Specific Standards: <br /> <br />1. Impervious Surface Coverage: Impervious surface coverage of a site shall <br />not exceed twenty five percent (25%) of the site area in a shoreland or wetland <br />overlay district unless storm water is conveyed to an approved, on-site or regional <br /> <br />1 <br />
