Lee's Summit

Please change the pavement marking for all linear striping to Hi-Build Paint as per the Design and Construction Manual. Thermoplastic pavment marking is not allowed for linear striping.

Please delete "Alternate A" since Alternate B has been selected for the Lee' Summit Road Capital Improvement Project.

Sheet C603: Please specify full-width for the ramp cross slope, and please provide a dimension of 5' by 5' minimum for the landing.

Sheet C603: Please remove all references to thermoplastic pavement marking for the linear striping. Please see previous comment concerning hi-build paint.

General Comment: Does the applicant wish to include this project with the Lee's Summit Road Capital Improvement Project? If so, then an agreement would need to be prepared between the City and the applicant concerning the scope of work, responsibility of each party, and reimbursement to the City. Please note that the City will be using the City's contract unit bid prices for the Lee's Summit Road project to develop a change order. Public Works will need an answer concerning this question within the next thirty (30) days if possible.

Does the pavement section for both alternate bid items match what is shown on the Lee's Summit Road project?

Please show the hydraulic grade line of the stormwater system on the profile view.

The proposed contours shown on Sheet C602 on the entrance do not appear to match the finish grade spot elevations shown on the Final Development Plan. Please reconcile.

Please be aware that the City of Kansas City water transmission main is located beneath the new driveway and portions of the transition. It is possible that this water line may need vertical adjustment to maintain adequate cover. Please check with the City of Kansas City to determine if adjustment/relocation is needed. Please ensure that the depth of cover is sufficient after installation of the entrance and turn lane.

An erosion and sediment control plan appeared to be missing from the plans.

Sheet C603: Please change the Legend note to read "1.5% maxiumum cross slope". The City of Lee's Summit has adopted a zero tolerance policy when sidewalk tranverse slopes are greater than 2%, so this will hopefully provide some allowance for error.

An itemized and sealed Engineer's Estimate of Probable Construction Costs should accompany your final submittal drawings. The Engineering Plan Review and Inspection Fee is based on this estimate, and is calculated at 3% of the total cost. Items to include in the estimate include: 1) pavement, including commercial entrance, 2) subgrade preparation, including a minimum one (1) foot beyond the back of curb, 3) aggregate base, including a minimum of one (1) foot beyond the back of curb, 4) grading, 5) pavement marking, 6) curb and gutter, 7) sidewalk, 8) ADA-accessible ramps, 9) storm pipe greater than 6" in diameter, 10) curb inlets, 11) erosion and sediment control devices, and 12) sodding, seeding, fertilizer, mulch and other restoration.

There are two left-turn arrows included in the Lee's Summit Road Plans within or near the proposed left-turn lane among the other markings in conflict with the proposed plans. Suggestion: a note on the plans regarding "Work preceding or concurrent with the City's project will result in reduced quanties for those two left-turn arrows and any other markings in conflict with the proposed plans. If work follows the City's project, quantities for pavement marking removal and removal of turn arrows would be applicable but has not been included."

A standard taper rate is 12.5:1 for the right-turn lane in the Access Management Code.

Provide stations for each turn arrow at locations in accordance with the City's pavement marking standard details.

Provide stations for the start and end of each pavement marking line and dimension lane widths for reference.

The left-turn lane markings should not have a taper, but rather transition from the two-way left-turn lane markings to a dedicated left-turn lane. Refer to the City's pavement marking standard details for a layout.
