Since this project was suppose to be a very short project their approved erosion- control plan, prepared by their civil engineer and shown on their construction plans were minimal. The erosion control fence that was suppose to be installed and maintained was specified to have 4 foot long stakes, spaced 4 feet on center, driven I foot into the ground and have six inches of fabric buried into the ground and they were to construct a rock construction entrance that was fifty feet long and six inches thick. LUndersized erosion control fencing with 3 -foot posts on 8 foot centers and less than 5 inches in the ground was used. The construction entrance Tree City U.S.A. was not built. The excavatin contractor has been told and did compl with the re to make immediate repairs to the existin fence b installin post ever four feet, removin built up sediment, and as soon as possible replace the entire fence with fence that meets the specification. This phased approach was taken to address immediate potential for rain and to allow them to build the rock construction entrance and repair the curbin without the dela of replacin the fence. The repair of the curb and installation of the construction entrance is awaitin MNDOT approval. The have replaced the fence while awaitin MNDOT approval. The followin actions are re to brin the erosion control up to standard: 1. The existin silt fence is to be removed and replaced b November 1, 2002 with fencin that meets the specification written b their en and approved as part of the buildin plan approval. The exception is that their en re to place the fence 10 feet from the toe of the slope would place the fence on the wron side of the ditch and should be i Note: As of October 28 the silt fence was replaced. 2. The onl g radin g activit allowed on the site will be for the preparation of the rock construction entrance and the replacement of the curbin If an alternative to the rock construction entrance can be provided that will provide the e protection as the rock construction entrance the Cit will consider the modification of this condition. The certification that the modifications are as effective as the rock construction entrance shall be under the seal of a re professional who is practiced in erosion control. 3. All construction must meet the g rades, storm water flows patterns, and confi shown on the currentl approved plan. An chan must have prior approval of the appropriate approvin authorit dependin on the extent of the chan Some or all of the followin ma have approval authorit Communit Development Department, it Administrator, Cit En Cit Council, Brown Creek Watershed District, and MNDOT. 4.
