HomeMy WebLinkAboutP_Revised Civil Construction Plans_171121_v3approval notes: 1. all driveway wings shall be triangular. hydrant to be connected to the existing valve using new pipe and tie--rods per cor std. plan 310.1. IN COMPLIANCE WITH CITY OF RENTON STANDARDS R-396403 install a type 2 cb on the existing 18" storm drain. install a short section of pipe from the new cb south to the ditch to pick up the ditch flow. this pipe will need to be installed above the existing 18" storm drain. install debris barrier on pipe inlet from the ditch per cor std. plan 223.00. set the new type 2 cb rim low enough for ditch to overflow to the cb grate if inlet pipe from the ditch gets plugged. this eliminates the need to install 86 lf of 12" di storm drain over the existing 18" storm drain. this is a more efficient design with less material to install and reduces the amount of infrastructure that has to be publicly maintained and cost to residents (rate payers). please see the attached plan for an example of a similar design. revise and resubmit for approval. this needs to be a new type 2 cb with a grated lid. this needs to be a type 2 cb as it will be more than 5' from rim to invert. show and label new type 2 catch basin. remove this pipe. show triangular driveway wings.
