Safety and Buildings Division Questions and Answers on Soil Erosion Topics Latest posting: July 30, 2007, Comm 82.36(3) and Comm 60.30 8/7/07What does the department require for the thickness of a subsurface stormwater detention system or detention basin liner? 5/26/06 Q. Must I install erosion control measures if construction begins in the winter? A. Yes. Erosion control measures must be installed when the land disturbance begins. Some practices may not be suitable for winter installation. 526/06 Q. What’s a site? Can a site be more than one lot? A. A site is considered to be all of connected property owned by one person/entity. For instance, if one corporation owns five connected lots, the five lots would be considered a site for the purpose of NOI requirements. The owner may use perimeter control around all five lots or they may choose to treat each lot separately. 4/17/06 Q. Can I submit an NOI (notice of intent) for a new retail development area to the Department of Commerce? A. You are required to submit an NOI for any building site regulated by the Department of Commerce (this includes public buildings and multi-family dwellings). If the original disturbance for the site includes the preparation for one of the buildings, the entire site could be submitted to the Department of Commerce at that time. An NOI for a single one- or two-family dwelling where one or more acres are being disturbed should be submitted at the local level when applying for the UDC Building Permit. (Erosion/sediment control and stormwater management plans must be prepared before submittal.) 4/17/06 Q. Does every project need a tracking pad? A. Not automatically. All construction sites need to prevent tracking onto roads or other offsite paved areas. If this can be accomplished by other means like gravel cover, natural non-tracking geologic features, a tire-washing station, or constant tire cleaning crew, the rule requirement is met. 4/17/06 Q. Must I install a silt fence if the site I’m disturbing has a vegetative buffer that complies with the technical standard surrounding it? A. No, the vegetative buffer is acting as the perimeter control for the disturbed area. Comm 21.125(5) and Comm 60.21(1) 6/27/07 Q. May the inspector’s reports be used as the monitoring reports required in Comm 21.125(5) and Comm 60.21(1)? A. No. The inspection reports of the local inspector may not take the place of the monitoring reports. The monitoring must be accomplished by the owner or their agent. The failure of erosion control measures or repairs needed which are noted in the inspector’s report should be documented in the monitoring reports created by the owner or their agent. Comm 82.36(3) and Comm 60.30 8/7/07 What does the department require for the thickness of a subsurface stormwater detention system or detention basin liner? There are three options that the department deems acceptable for a subsurfqace stormwater dentention system or detention basin liner: 1. Clay liner 2. High Density Polyethylene Liner (HDPE) 3. Polyethylene Pond Liner (PPL) The specifications for the liners are here, PDF file.
