<br />3. STORM SEWER: <br />Storm water drainage within Peltier Preserve will be directed via catch basins and storm sewers <br />to two ponding areas, as shown in Figure 4. Treatment pond No. 2 will discharge through a <br />controlled outlet structure to an existing channel, which is connected to Peltier Lake. Total <br />runoff from the site after all construction is complete will not exceed existing runoff amounts. <br />Backyard swales in the adjacent Peltier Lake Hills Addition will be graded to drain to the new <br />ponding area in Peltier Preserve. <br /> <br />Existing storm sewer piping and structures along Peltier Lake Drive will remain in place, with no <br />improvements proposed at this time. <br /> <br />4. STREET IMPROVEMENTS: <br />Peltier Circle will be constructed to typical 7-ton residential street standards for the City of <br />Centerville. Street improvements are shown in Figure 4. The new road will consist of the <br />following parameters: <br /> <br />1. 60- foot wide right-of-way <br />2. 33-foot back to back surmountable concrete curb and gutter <br />3. Geotextile fabric and 20" select granular borrow <br />4. 6" class 5 aggregate base <br />5. 1 W' bituminous base and wear courses <br />6. 4" PVC drain tile behind all curb and gutter <br />7. 5' wide detached concrete sidewalk along one side of the street <br /> <br />Existing streets that are damaged or open cut during water main construction will be patched <br />with aggregate base and bituminous pavement to match existing thicknesses. It is anticipated <br />that existing Peltier Circle, from Peltier Lake Drive to the Peltier Preserve plat, will be damaged <br />from truck traffic entering and leaving the site. This 200-foot section of street will be <br />reconstructed to the standards shown above. <br /> <br />5 <br />
