Lee's Summit

A brief erosion and sediment control plan shall be provided for the project. All projects within the City of Lee's Summit shall include an erosion and sediment control plan despite their small scope of work. A final restoration plan shall also be incorporated into the erosion and sediment control plan. It is acceptable to place these plans within the same plan set.

Restoration plan shall include all sidewalk, driveway entrance, sodding, seeding, fertilizer, mulch, and other items necessary to restore the disturbed area to its original condition. Please be aware the entrance is KCMBB concrete mix, and sufficient detailing shall be provided for its restoration. The City shall not allow excessive steel reinforcement within this section of the driveway replacement, so please see the City standard details for more information. The intent of the removal and replacement shall be to yield a driveway as good a condition as was originally designed, but will allow for easy access in the future by Water Utilities staff. Excessive rebar and/or dowels over and above what the City shows on the standard jointing pattern detail should be the goal of your design. Please revise, and provide specific notes as to the removal and replacement of the driveway, sidewalks, and grassed areas.

A wye connection for the 1.25 inch force main was missing from the plans. I am using this figure of 1.25 inch as there was a contradiction in the FDP which showed 2 inch HDPE, then went on to state 1.25 inch. Please review which size is needed, and show the wye location where the force main serving the northern lot will be connected. Please be aware the City does not allow direct connection to the manhole, and the wye shall be a minimum of 4.0 feet downstream of the manhole, as measured from the outside of the manhole, to the closest point on the wye (i.e., not the centerline of the wye, but the closest point on the wye). Please revise as appropriate.

The public liine shall be extended further to the northeast so that the installation of the wye can take place completely within the bounds of Lot 2, with sufficient space around the wye for future maintenance by the owner of Lot 2 without the need to disturb the property of Firestone to the south. Recommend a minimum of 10 feet from the wye. Please revise as appropriate.

Standard detail for a wye connection including tracer wire requirements were missing. Please provide this detail in the plans.

Topo is incomplete. The impacted driveway, sidewalk, and grassed-area were missing. Without this, no comments can be provided on the removal and replacement plan for the KCMMB driveway entrance (including jointing pattern), nor the sidewalk, or the grassed-area restoration. Provide a complete topo for the area in question.

Sanitary sewer appears to be too close to the unidentified feature "ET", and the AT&T telephone vault. Minimum distance between the outside of the pipe or manhole shall be 10 feet from these or any other permanent structure. Please revise.

Existing flowline information was missing for the existing manhole. The flowline in elevation for the existing line to the west, and the flowline elevation for the outgoing line is required in addition to the flowline elevation for the proposed. Please revise.

Plans are missing the notes specifying core drilling of the manhole for the connection. Please add sufficient notation.

ADA-accessible ramps at the existing entrance appear to be impacted by the project. No topo information was provided, however, to make a definitive determination. Please see comment related to an adequate topo for this project, and provide the required details concerning the removal and replacement of this feature. Generic details for ADA-accessible ramps are not sufficient, and minimum callouts for this particular ramp include corner elevations of the ramp, slope callouts for the ramp and the cross-slope of the ramp, callouts for the 5 foot wide ADA-accessible route across the driveway with dimensions, cross-slope callouts, cross-section at the curb opening (if used), and all other information necessary to construct the ADA-accessible ramps in accordance with City of Lee's Summit standards. Please be aware the City has adopted more stringent standards for design than PROWAG, including the 1.5% cross-slope rather than 2.0%, and 7.5% for running slope rather than 8.33%. This allows for some construction tolerance, with PROWAG governing the finished product.

Incoming force main shall be installed outside all public utility easements since it is considered private. A private easement shall be dedicated to Lot 1 from Lot 2 for its installation, maintenance, and service. Please ensure this is taken into account during design of the public portion of the project.

General Comment: Linework was confusing, contradictory, and needs considerable cleanup. These comments shall be considered cursury in nature due to this issue.
