Lee's Summit

Please use the City manhole numbers for all existing sanitary sewer manholes. For reference, EX-092 is 65-092, EX-227 is 65-227, and EX-226 is 65-226. Please update and revise as appropriate.

Manholes B1, B2, and B3 shall be 5 foot inside diameter manholes rather than 4 feet. Please revise as appropriate.

There appears to be an 8 inch line from the south which enters the existing City manhole 65-226, and the plans do not appear to address how this will be connected to the new system. Please evaluate and revise as appropriate.

Plans were incomplete in that there was no plan for upgrading the line near the Summit Mill lake dam. Please see the Preliminary Development Plan for specific details concerning the upgrade of this line near the dam and across Langsford Rd. Please update as appropriate.

Off-site public sanitary sewer easements across the properties to the east in a form acceptable to the City shall be required prior to approval of the plans. A courtesy copy of the unexecuted easement with an 8.5 by 11 inch exhibit showing in graphical format the limits of the easements shall be required. Please provide these documents prior to execution and recording for review by the City Law Department.

Additional off-site easements across unplatted land shall also be required in the case where the sanitary sewer line is being installed to the north of the apartment complex (i.e., along future Riley Place, and A7 to A5). Please see the above comment for specific details concerning this easement. The easement shall be twice the depth of the sewer, assuming the sewer is centered within the easement.

The concrete encasement shown at the stream crossing between A2 and A3 shall include a v-notch in the concrete. A separate detail shall be transmitted to you showing this encasement detail. Please revise in accordance with the detail to be provided separately.

Future Manhole Connections: There are references to plug and stub, which is not allowed in the City of Lee's Summit. Future connections shall be core-drilled. Please ensure this is clearly-defined on the plans, as we have had numerous issues in the past with contractors delivering manholes with these holes already provided for future connections, and have rejected them. Please revise.

We are assuming all future public sanitary sewer lines will not need to be connected to the sanitary line contained within these plans (i.e., it appears all future sanitary lines shall be constructed elsewhere, off the proposed plat). If not, future connections shall require the demolition and reconstruction of Heritage St., which is not desireable for the City or the developer. Please evaluate and respond as necessary.

The plans call for the end of the public sanitary line to terminate at A11. The public line should terminate at manhole A10, not A11. It is acceptable to connect the private sanitary directly to manhole A10 rather than a stub, but the FDP should be revised to include this revision. Please revise the engineering plans, and please ensure the FDP is also revised as appropriate.

An erosion and sediment control plan was missing. Please provide an erosion and sediment control plan for all aspects of the public sanitary sewer project, including near the dam and Langsford Rd.
