Refer to erosion control practice number 3.17 . P Straw Bale Drop Inlet Protection: Recommend using straw bale drop inlet protection as per erosion control practice number 3.54 as a temporary erosion control measure until blankets are installed. Other drop inlet protection practices may become necessary upon the recommendation of the engineer or erosion control consultant if a specific need arises during construction.

Temporary Seeding: Recommend temporary seeding as per erosion control practice number 3.11 if disturbed ground is to be left bare for two months or more. In addition, it is recommended red clover be added to the seeding mixture at a rate of 10 pounds per acre. Dormant and Frost Seeding: As per practice number 3.13 attached to be applied if necessary. Surface Roughening: As per erosion control practice number 3.03, suggest using a bulldozer to track with cleats perpendicular to the slope of slopes on disturbed ground of six percent or greater and around the shore of the lakes as a temporary measure until ready for blankets. Temporary Gravel Construction Entrance /Exit Pad: Recommended as per erosion control practice number 3.01. Tree Conservation /Protection: As per erosion control practice number 3.83, the contractor shall, at the direction of the developer, endeavor to save and protect trees of value and worth which do not impair construction of improvements as designed. In the event cut or fill exceeds 0.5 foot over the root area, the developer shall be consulted with respect of protective measure to be taken, if any, to preserve such trees. Maintenance Schedule: Maintenance of all erosion control practices should be done as needed on a weekly basis and after all large storms. A construction supervisor should be assigned the task of seeing that all practices are installed and maintained according to the design criteria. Maintenance for each erosion control practice should be conducted per maintenance schedule shown on each erosion control practice job sheet (attached).
