Utility Construction and Use of the Right-of-Way Policies and Procedures Manual Page 22 <br />any construction-related activity without first obtaining from the Engineering Division an erosion <br />prevention permit, if the construction-related 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 /> <br />Pursuant to R-6.645-E, a construction site shall be considered a sensitive area by the City for which an <br />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 designated <br />buffer area. <br /> <br />For all other construction activities not subject to the erosion prevention permit requirements, compliance <br />with the standards for preventing and controlling erosion, sedimentation, and other impacts associated <br />with construction site management practices is required. (See R-6.645-D.) <br /> <br />All construction activity that will result in soil disturbance during the wet weather season (October 15th <br />through April 30th) shall, at a minimum, implement and maintain the following Best Management <br />Practices (BMPs) 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, adjacent <br />property, and the City’s stormwater system, including water features and related natural resources. <br />All violations that occur shall have corrective action taken immediately. <br /> <br />Groundwater extracted from excavated areas shall be disposed of in a manner that will not damage <br />adjacent property, the City’s stormwater system, water features, or related natural resources. Dewatering <br />systems shall be designed and operated so as to prevent removal of the natural soils and so that the <br />groundwater level outside the excavation is not reduced to the extent that would damage or endanger <br />adjacent structures or property. Approval of the system does not guarantee that it will meet the outcomes <br />or be acceptable for use in all situations. Modifications to the system will be required if the outcomes <br />cannot be met. No sediment-laden water should ever leave the construction site. <br />Activities involving cleaning of construction equipment and disposal of excess construction materials <br />shall be conducted so that materials and washout will not be deposited into catch basins, gutters, ditches, <br />or areas where runoff may carry materials into the City stormwater system.
