Remove all trees, brush, stumps, and other objectionable material from the foundation area, and dispose of properly. 2. Excovote the channel, and shape it to neat lines and dimensions shown on the plans plus a 0.2—foot overcut around the channel perimeter to allow for bulking during seedbed preparations and sod buildup. 3. Remove and properly dispose of all excess soil so that surface water may enter the channel freely. 4. The procedure used to establish grass in the channel will depend upon the severity of the conditions and selection of species. Protect the channel with mulch or a temporary liner sufficient to withstand anticipated velocities during the establishment period (Appendix 8.05). Rip Rap Channel —Maintenance Requirements During the establishment period, check grass —lined channels after every rainfall. After grass is established, periodically check the channel; check it after every heavy rainfall event. Immediately make repairs. It is particularly important to check the channel outlet and all road crossings for bank stability and evidence of piping or scour holes. Remove all significant sediment accumulations to maintain the designed carrying capacity. Keep the grass in a healthy, vigorous condition at all times, since it is the primary erosion protection for the channel (Practice 6.11, Permanent Seeding). Rip Rap Berm —Maintenance Requirements Inspect riprap berm weekly and after significant (1/2 inch or greater) rainfall events to see if any erosion around or below the riprap has taken place, or if stones have been dislodged. Immediately make all needed repairs to prevent further damage. INFILTRATION BASIN SCALE: 1 "=30' 0i1►<014RI[.03I004 ID ►!, Care should be used during installation to minimize compaction of soil on the bottom and walls of infiltration devices since this will reduce the permeability at the soil interface. To avoid compacting the drainage media, light equipment and construction techniques that minimize compaction should be used. A minimum of one observation well shall be included in the design of an infiltration system to periodically verify that the drainage media is fully draining. The monitoring well shall consist of a 4— to 6—inch—diameter, perforated polyvinyl chloride (PVC) pipe with a locking cap. The well should be placed near the center of the facility or in the general location of the lowest point within the facility, with the invert at the excavated bottom of the facility. A construction sequence must be followed that reflects the need to stabilize the infiltration device. The longevity of infiltration devices is strongly influenced by the care taken during construction. Once site is stabilized with permanent ground cover, scarify the soil in the bottom of the basin and install the washed sand. SAND MEDIA NOTES Uniform sand (i.e., uniformity coefficient of 2 or smaller) is preferable as a drainage medium. Uniform materials have high porosity and large storage capacities so less material is required. The porosity of the material should be determined by laboratory tests and be certified by the supplier. Drainage media materials should be hard, durable, inert particles, free from slate, shale, clay, silt, and organic matter. The material shall be washed, and it is recommended that it be double —washed. The bottom of infiltration basins and trenches must be lined with a layer of clean sand with a depth of 8 inches , unless the native soil is equivalent (1-2% fines or less). THREADED CAP BASIN BOTTOM 8" WASHED v SAND INSERT 12"-15" INTO SOIL SUBGRADE SUBGRADE — OBSERVATION WELL NTS RIP RAP 1. Use Class I rip rap. 2. Minimum 3' wide at top. 3:1 side slopes or flatter. 3.
