Lee's Summit

The 6 inch minimum clearance that is shown between the screw-in anchor and the pipe is not sufficient. These anchors derive their strength from surrounding soils. A 6 inch clearance will lead to failure of the base supporting the decorative light pole. After discussing internally, the City would allow a minimum of 3.0 feet, as measured from the center of the light pole, to the outside of the trench. Please revise the plans accordingly, since this will change the angle considerably, and will also change the water line relocation, the new manhole location, and the brick paver removal and replacement plan contained within the Final Development Plan.

Please review the above comment. The minimum distance of 3.0 should be dimensioned from the center of the decorative light pole, to the side of the trench. The trench must have a minimum of 6 inches on each side of the 15 inch pipe, so depending on the width of the trench, the absolute minimum distance between the outside of the pipe and the center of the decorative light pole must be 3.5 feet.

Traffic comments include the following: 1) there is no plan addressing Amtrak customer parking, or how this will be managed, 2) a signing plan to prevent cut-throughs on the bank property was not shown, 3) a separate pdf is being attached showing the minimum requirements concerning the closure of parking spaces for Amtrak customers, and these parking spaces will by necessity be shut-down for the duration of Phase 1 and Phase 2 of the road and storm sewer project.

A separate temporary traffic control permit is required from Public Works.

During our meeting on June 17, 2019, we discussed the necessity of deflecting the pipe to avoid the existing decorative light pole and base. No such deflection was shown on the plans, only a note was provided. An estimate of the deflection must be shown to avoid the light pole and base, with consideration that the 15 inch storm line is not an infinitely thin line as indicated on the plans. The estimated deflection will affect the placement of the new manhole within the street, and will also affect the water line relocation plans shown elsewhere in the plan set.

Sheet C.302: The note for the public storm line within the street should be specified as CPP pipe. It is also acceptable to use the ADA designation for this pipe, but CPP is specified in the Design and Construction Manual, and should be referenced in the plans.

Sheet C.303: The location of the water line relocation must be changed based on the previous comment concerning the estimated deflection of the storm line. Please consider the fact that: 1) the pipe is not an infinitely thin line, and 2) the light pole and base must be cleared, with a minimum clearance where the light pole base is affected structurally.

Sheet C.306: The traffic control plan has not changed since the last submittal, with the exception of the note stating that a 4 foot trench shall be installed to facilitate construction of the storm sewer. While this is acceptable, and we agree that a separate traffic control plan is required at the time that full panel removal and replacement takes place, the traffic control plan must reflect what is to occur during the first phase of construction. In other words, the 4 foot trench should be shown, with traffic control shown to manage this portion of the project. The conflicting note stating that "The Road Shall be Closed and Traffic Only be Allowed Between 9 am and 4 pm" has been discussed in the last two (2) comment letters, but still appears in this plan set. As discussed in previous comment letters, and also at the June 17th meeting, the road shall not be closed. A minimum of one lane traffic must be maintained during the first phase (i.e., during the construction of the 4 foot wide trench and storm line).

In response to our comment concerning the note about water line removal/abandonment, it was merely taken out of the plans, and the response was "water line will not be removed". The water line shown along the north side of the property must be properly removed and/or abandoned in-place. This was a condition of approval of the Preliminary Development Plan, and also, Water Utilities has indicated this line must be properly removed and/or abandoned.

Please see comments related to the Final Development Plan in regard to the private storm sewer and decorative light pole conflict. Since the decorative light pole cannot be moved, an alternate location must be selected for the storm line.

Sheet C.304: There is still considerable confusion on what is required for the full panel street repair. Please see the previous plan sheet for the Downtown Streetscape project that was previously provided. The centerline of the street should show a "longitudinal constructon joint", and the other longitudinal joints are "longitudinal contraction joints." The "isolation joint" along the back of curb should be revised to show no dowel. The isolation joint should be merely shown with the isolation joint filler and sealant. This joint is placed against the back of brick pavers, and as such, no dowels should be used or would be able to be used. The legend should be updated to include "longitudinal construction joint", and the "isolation joint". Finally, where are the plans for removal and/or abandonment of the water line running east/west along the north side of the project?

Sheet C.305: Please see previous comments related to the isolation joint detail revision. Also, is this plan related to the fire line installation? There does not appear to be any context given in this drawing.

Sheet C.305: Drafting errors exist on this sheet, where existing transverse contraction joints are labeled as "existing longitudinal contraction joint". Also, the legend is missing the isolation joint.

Sheet C.306: The traffic control plan still contains the same conflicts as the previously submitted plan. For instance, there is a label stating "The Road shall be closed and work only be allowed between 9am and 4 pm, Monday through Friday". However, the notes state that "one lane of traffic to remain open at all times." As we have discussed previously, one lane of traffic should be provided at all times. Conflicts in the traffic control plan must be eliminated.

How will parking issue be addressed? It appears the parking stalls will be utilized for a through-lane, but it is not clear how proper notice will be given on the temporary closure of these parking spaces. Do you also propose to close-off parking on the west side of Main St.?

How long will Main St. be maintained in this fashion? A maximum time period should be established, so the road is opened for traffic in the minimum amount of time.

The public sanitary sewer abandonment plans were missing from these plans. They should be included in these plans since they are public. They should include any abandonment procedures, locations, manhole removal, etc.

The plan lacked the removal of the existing water line located at the north property line. The plan must show how the line will be removed, including any street panel removal and replacement, fittings, etc.

The public sanitary sewer abandonment or removal should be shown within these plans. It must be specific as to what actions will take place.

Sheet C.011 was included within the Final Development Plan for Reece Nichols Building. Rather, it should be included within these public improvements.

Sheet C.011: This sheet should be re-numbered, and the index to sheets revised as appropriate.

Sheet C.011: A detail of the downtown street project along Main St. was previously emailed to you. This sheet included specific design details which were not included in your design. In particular, you are missing the following items: 1) a legend, 2) location of transverse contraction joints, 3) location of longitudinal contraction joints (there will only be two locations along the centerline, and along the gutter line, no others), 4) definition of "D" (i.e., 8 inches).

It appears the water line work to serve the building along Market St. will also require concrete panel removal and replacement. We will not allow piecemeal sawcutting into a panel. Full panel removal and replacement will be required if the water line work will require encroaching into the paved area.

It appears that water line removal along the north side of the property will also require full panel removal and replacement of the pavement on Market St. and Main St., to properly remove the water line.

The traffic control plan is vague, conflicting, and inadequate for this project. In general, a phasing plan is required showing how this project will allow for at least one (1) lane of traffic to remain open at all times. No full closure of the road will be allowed due to the conflict with local businesses along Main St. Examples of conflicts include the following: 1) there are two (2) sheet C.304, 2) the note "the road will be closed" conflicts with the traffic control signs shown on Sheet C.304, 3) parking is still shown as being allowed during the one lane closure, which is going to be difficult (if not impossible) to maintain one lane of traffic, 4) the note "road plating during non-working hours" doesn't make sense if concrete is curing.

The traffic control plan must show how parking spaces will be closed, in order to facilitate one lane of traffic at all times.

It is highly recommended, given the scale of the plan sheet on Sheet C.304 to label the traffic control signs with their name, rather than just a letter designation.

A note must be provided that states "Right of Way Permit from Public Works is Required for Any Work within the Right of Way". Also, a note must be provided stating that "all business owners affected by the partial road closure must be given a minimum of five (5) business day notice prior to any work within the right of way. These notices must be made by the contractor.

Storm Sewer revisions as discussed to permit travel movements in the ally as required (e.g. change the curb inlet in the alley adjacent to the trash enclosure to a traffic rated area/grate inlet and change the CG1 to a flat curb for trucks to traverse unimpeded turning from eastbound alley to southbound alley.)
