<br />Project No. E9164-04-0 2 - 15 - April 15, 2020 <br />6.13.3 Positive site drainage should be provided away from structures, pavement, and the tops of slopes to <br />swales or other controlled drainage structures. The building pad and pavement areas should be fine <br />graded such that water is not allowed to pond. Final soil grade should slope a minimum of 2% away <br />from structures. <br />6.13.4 We recommend implemented measures to reduce infiltrating surface water near buildings and slabs- <br />on-grade. Such measures may include: <br />• Selecting drought-tolerant plants that require little or no irrigation, especially within 5 feet of <br />buildings, slabs-on-grade, or pavements. <br />• Using drip irrigation or low-output sprinklers. <br />• Using automatic timers for irrigation systems. <br />• Appropriately spaced area drains. <br />• Hard-piping roof downspouts to appropriate collection facilities.
