Pursuant to R-6.645-F, no person shall commence any construction related activity without first <br />obtaining from the Engineering Division an erosion prevention permit, if the construction related <br />activity: <br />Will result in the disturbance of 1 acre or more of land. <br />Is located in a sensitive area as designated pursuant to R-6.645-E. <br />Pursuant to R-6.645-E, a construction site shall be considered a sensitive area by the City for which <br />an erosion prevention permit will be required if the site meets one or more of the following criteria: <br />The slope of the parcel in the area of disturbance is greater than 10 percent. <br />The site, by City definition, contains highly erodible soils. <br />The parcel or tax lot of record has the potential to drain directly into a water feature or its <br />designated buffer area. <br />For all other construction activities not subject to the erosion prevention permit requirements, <br />compliance with the standards for preventing and controlling erosion, sedimentation, and other <br />impacts associated with construction site management practices is required. (See R-6.645-D.) <br />All construction activity that will result in soil disturbance during the wet weather season (October <br />15th through April 30th) shall, at a minimum, implement and maintain the following Best <br />Management Practices (BMP's) on the site: <br />• Gravel construction site entrances. <br />• Protection of all stormwater systems, water features, and natural resources. <br />• Cover all exposed soil not currently protected by secondary containment or treatments. <br />• Timely removal of sediment, soil or construction related material from the right-of--way, <br />adjacent property, and the city's stormwater system, including water features and related <br />natural resources. All violations that occur shall have corrective action taken immediately. <br />Ground water extracted from excavated areas shall be disposed of in a suitable manner without <br />damage to adj acent property, City's stormwater system, water features, and related natural resources. <br />Dewatering systems shall be designed and operated so as to prevent removal of the natural soils and <br />so that the groundwater level outside the excavation is not reduced to the extent that would damage <br />or endanger adjacent structures or property. Approval of the system does not guarantee that it will <br />meet the outcomes or be acceptable for use in all situations.
