there are some practical steps that can be taken: <br /> • re-grade as much as possible to attempt to achieve the recommended clearance from the <br /> siding to the ground. <br /> • On the homes where the clearance is minimal it is recommended to install as little mulch <br /> as possible. Mulch, although not a hard surface, does retain a great deal of moisture <br /> and can also hide termite and other wood damaging insect activity, so should not be in <br /> contact with the siding. It is recommended to have annual termite inspections/treatments <br /> on homes where siding is less than 6" from mulch. It is also to annually inspect the sill <br /> plate, starter strip, and bottom of siding to determine if damage from splashback is <br /> occurring. <br /> • Many of the areas between the houses were noted to be slightly crowned, meaning that <br /> the high point of grade was in the center and the water would drain away towards the <br /> houses on each side. Some of the areas also appeared flat. It would be recommended in <br /> these areas to make that a swale so water drains away from houses. It is strongly <br /> recommended to calculate the drainage capacity necessary at these locations. Soil types <br /> and soil saturation greatly influence how well and quickly the soil will absorb water. <br /> Clay, loam, sandy/clay loam, and coarse sand have differently permeability (the <br /> measure of how many inches per hour the soil can absorb). Once the soil has been <br /> characterized, the next step would be to design the drainage system to make use of the <br /> soil to absorb the soil using dry wells, French drain channels, and/or further drainage. <br /> An example of a drywell connected to a roof drain leader is shown below (diagram from <br /> NDS). <br /> W-" HAW l PO'V� <br /> L11,01111%," <br /> NhAN,pm Wl"k 4 )4T7P6')Y' <br /> P"W0,09MA, If,NK,VWOW'4"NX AJP��;111 r uiMI, <br /> ............ �,I'm A)"xlry n d")vvw Nrl'J'yaw <br /> I A <br /> r"V,F"I'A U, H�'Y r.u <br /> YUO"M'0,U,W,R I .......

If the topography of the surrounding houses is challenging, a <br /> swale may be used as shown below: <br /> 1(.......... <br /> The Cottages Phase 111 18 <br /> Mashpee, MA ENGINEERS' <br />
