As has been noted in the street section, catch basins shall be set five (5) feet beyond on the <br />radius point and along the tangent at street intersections. <br />e.) Catch basin 170 on Century Trail shall be changed to a Type 402. Catch basin 175 on <br />Robinson Drive shall be changed to a Type 402. (See Plan Sheet U11) <br />f.) Backyard catch basins 184, 185, and 186 all have the same invert. Also, the inlet structure <br />castings shall be Type 402A. (See Plan Sheet U12) <br />g.) Standard Details (Plan Sheet D1): <br />• Outlet Structure 166: This structure is not labeled in the plans. Thus, either delete the <br />detail if not to be used on this project or identify/label its location in the plan set. <br />• Outlet Structure 142: The shown 4" orifice to Pond K will not be allowed due to <br />potential clogging with debris. A recommended alternative would be a submerged <br />reverse flow 15" RCP with a 4" orifice plate attached to the inside of the pipe /manhole <br />interface. <br />7.
