LAND ALTERATIONS d Call out the number of square feet of rookops and ehe numoer of squarc feet of other impervious surPac�s such as dnveways and parking areas. � - Show connection to nearest stream, if possible, or state distance to stream. - A note indicating that bare ancL'or disturbed soils shall remain uncovered and/or unstabilized for no more than 2 days from October 1 through Aprii 30, and for no more than 7 days from May 1 through September 30. 2-2.2 SMALL PARCI'sL BMPs 2-2.2(1) BD'IP E5.10 PLANIV�D CLGARING AND GRADING t:learing and grading of the site should be planned properly. It is important to dear only the areas needed, thus keeping exposed areas to a minimum. Cleaz�ng should be phased so that only those areas that are actively being worked are ur.cov�red. Clearing limits should be flagged and reviewed by the appropriate ciry officia! in the lot or area prior to the initiation of clearing. 2-2.2(2) BiVIP �5.20 �XCAVAT�D I3ASENI�NT SOIL Lxcavated basement soi] should be located a reasonable distai�ce behind the curb, such as in the hackyard or side yard azea. This practice will incrcase the distance eroded soil must travel to reach the storm sewer system. Soii piles should bc covered until the soil is cithPr used or removed. Yiles should oe situated so that sediment does not erode into the street, adjoining yards and does not enter sudace water. 2-2.2(3) BMP�5.30 BACKFII,LING ''asement walls should bc backfilled as soon as possible and the lot rough graded. This practice will tinate large soil mounds which are highly erodible and prepares the lot for temporary cover, which will . -.hcr reducc erosion potential. 2-2.2(4) BNII' CS.41i It�MOVAL Or EXC�SS SOIL ` Excess soil should be removed from the site as soon as possible after backfilling. This practice will climinate any sediment loss from su*�lus fill. 2•2.2(5) BMP ES.50 MANAG�NI�NT OI'SOIL BANKS If a lot has a soil bank higher than the curb, the bank should be located several feet behind the curb and a shallow trench should be excavated between the bank and the curb. This practice will help prevent any eroded sedimen:from entering the street. 2-2.2(6) BMI'ES.GO CONSTRUCTION ROAD ACCESS I Grave] or crushed rock shall be applied to the driveway area and vehicle vaffic restricted to this one route. I Driveway paving can be installed direcdy over the gravel. This measure will help prevent soil from I adhering to tires and stop soil from washing into the streeL This conswction access requires periodic insin:ction and maintenance induding washmg, top-dressing with additiona] stone, reworking and i compacUon. I 2-2.2(7) BNII'ES.70 SOIL STABILIZATION 'I Soil stabilization measures protec[ soil from the crosive forces of raindrop impact and flowing water. ' Accr,ptablc measures include establishing vegetation by sodding or seeding, mulching with two tons of j stra�v per acre or approved equal, plastic or other imperv�ous covenng staked to the gound or anchorcd with , •�ks or sandbags, and the early application of gravel base on areas to be paved. � STANDARDS 2-2 Rer.
