LAND ALTERATIONS <br />Call out the num ber of square feet of rooftops and the num ber of square feet of other im pervious <br />surfaces such as driveways and parking areas. <br />Show connection to nearest stream, if possible, or state distance to stream. <br />A note indicating that bare and/or disturbed soils <br />more than 2 days from October 1 through April 30, <br />September 30. <br />2-2.2 SMALL PARCEL BMPs <br />shall rem ain uncovered and/or unstabilized f or no <br />and for no in ore than 7 days from May 1 through <br />2-2.2(1) BMP ES.10 PLANNED CLEARING AND GRADING <br />Clearing and grading of the site shout d be planned properly. It is im portant to clear only the areas needed, <br />thus keeping exposed areas to a m inimum. Clearing should be phased so that only those areas that are <br />actively being worked are uncovered. Clearing lim its should be flagged and reviewed by the appropriate <br />city official in the lot or area prior to the initiation of clearing. <br />2-2.2(2) BMP ES.20 EXCAVATED BASEMENT SOIL <br />Excavated basement soil should be located a reasonable distance behind the curb, such as in the backyard or <br />side yard area. This practice will increase the dist ance eroded soil in ust travel to reach the storm sewer <br />system. Soil piles should be covered until the soil is e ither used or rem oved. Piles should be situated so <br />that sediment does not erode into the street, adjoining yards and does not enter surface water. <br />2-2.2(3) BMP ES.30 BACKFILLING <br />Basement walls should be backfilled as soon as po ssible and the lot rough graded. This practice will <br />eliminate large soil in ounds which are highly erodible a nd prepares the lot for tem porary cover, which will <br />further reduce erosion potential. <br />2-2.2(4) BMP ES.40 REMOVAL OF EXCESS SOIL <br />Excess soil should be rem oved from the site as soon as possible after backfilling. This practice will <br />eliminate any sediment loss from surplus fill. <br />2-2.2(5) BMP ES.50 MANAGEMENT OF SOIL BANKS <br />If a lot has a soil bank higher than the curb, the bank should be located several feet behind the curb and a <br />shallow trench should be excavated between the bank and the curb. This practice will help prevent any <br />eroded sediment from entering the street. <br />2-2.2(6) BMP ES.60 CONSTRUCTION ROAD ACCESS <br />Gravel or crushed rock shall be applied to the driveway area and vehicle traffic restricted to this one route. <br />Driveway paving can be installed directly over the gravel. This in easure will help prevent soil f rom <br />adhering to tires and stop soil from washing into th e street. This construction access requires periodic <br />inspection and in aintenance including washing, top- dressing with additional stone, reworking and <br />compaction. <br />2-2.2(7) BMP ES.70 SOIL STABILIZATION <br />Soil stabilization in easures protect soil from the erosiv e forces of raindrop im pact and flowing water. <br />Acceptable measures include establishing vegetation by sodding or seeding, in ulching with two tons of <br />straw per acre or approved equal, plastic or other im pervious covering sta�ed to the ground or anchored <br />with rocks or sandbags, and the early application of gravel base on areas to be paved. <br />STANDARDS 2-2 <br />
