Corrective Action Required
Please refer to the previous applicant letter dated May 23, 2017. Comment #3 and #12 requested that bends be shown for the water line where the angle of deflection exceeded recommendations. It appears the water line along Summit St. exceeds the minimum radius of 1146 feet. Please provide the locations of all bends, and the magnitude of the angle of the bends.

Corrective Action Required
Please add a note stating that "...all construction shall follow the City of Lee's Summit Design and Construction Manual as adopted by Ordinance 5813. Where discrepancies exist between these plans and the Design and Construction Manual, the Design and Construction Manual shall prevail."

Corrective Action Required
Sheet 1: Why is the proposed 12" water main tie-in to the south, along 16th St., shown crossing Summit St. and offset to the west? Is there a particular reason for offsetting the water line at this location?
|
|
|
Corrective Action Required
Sheet 1: It appears there are instances where the water line is shown exceeding the minimum radius of deflection. Please show the location(s) of all bends on this sheet.
|
|
|
Corrective Action Required
Sheet 1: A blow-off is shown at a dead end location on the north end of Decker St. Blow-offs are not allowed. Where water lines are to be extended in the future, an in-line temporary fire hydrant is required at the end of the line.
|
|
|
Corrective Action Required
Sheet 1: Please show an outline (grayed-out) of the future road extension from the roundabout, to the west (i.e., to M-291). Please ensure the water line is a minimum of 4 feet behind the back of curb.
|
|
|
Corrective Action Required
Sheet 1: The easement shown for the water line near the northeast corner of the roundabout should be continuous (i.e., no gap between the right of way and the easement). It should be described as a general utility easement rather than a dedicated water line easement.
|
|
|
Corrective Action Required
All Sheets: Please add a note to the profile views stating that the maximum depth of cover for the water main is 7 feet.
|
|
|
Corrective Action Required
All Sheets: Where 12" water mains are shown with valves, please specify a butterfly valve. Where water mains are shown less than 12" diameter, please specify a gate valve.
|
|
|
Corrective Action Required
Sheet 2: A blow-off assembly is shown, and not allowed. Remove the blow-off assembly, and replace with a temporary in-line fire hydrant. See previous comment for further information.
|
|
|
Corrective Action Required
Sheet 2: There are several intervals of pipe that are near the 7 foot depth of cover requirement. Please make the water line more shallow (i.e., as close to 3.5 feet as possible over the top of the pipe).
|
|
|
Corrective Action Required
All Sheets: Why is DIP called-out? The City prefers C900 pipe.
|
|
|
Corrective Action Required
Sheet 3: It appears the minimum radius of deflection is exceeded in several instances along Summit St. Please show the locations of bends, and show the degree of deflection of the bends.
|
|
|
Corrective Action Required
All Sheets: Fire hydrants are shown on the wrong side of the water main. They should be located near the back of curb in accordance with the measurements shown on the standard detail. This is 2 feet as measured from the centerline of the fire hydrant to the back of curb. Where sidewalk is constructed against the back of curb, fire hydrants should be installed adjacent to the sidewalk (i.e., not in the sidewalk).
|
|
|
Corrective Action Required
Sheet 4: The water line is too deep near station 21+38. The maximum depth of cover is 7 feet. Please go over the top of the 12" pipe, or move the 12" pipe.
|
|
|
Corrective Action Required
Sheet 4: Please show a new 6" gate valve on the east side of the tee for the connection at 16th St.
|
|
|
Corrective Action Required
Sheet 4: If it is impossible to construct a straight connection of the 12" water main to the 6" water main (see previous comment related to this), then the City would like at least four (4) 45 degree bends at the Summit St. crossing, rather than two (2) 90 degree bends. This will also allow for smaller thrust blocks.
|
|
|
Corrective Action Required
Sheet 5: The water line is shown beneath a 12" pipe, and is greater than 7 feet of cover. Please go over the top of the pipe, or move the 12" pipe.
|
|
|
Corrective Action Required
Sheet 6: The water line is too deep near station 2+50.
|
|
|
Corrective Action Required
Sheet 6: Please show the future road extension to M-291 along Summit St. Ensure the water line is a minimum of 4 feet from the back of the curb.
|
|
|
Corrective Action Required
Sheet 6: It appears the minimum radius of deflection has been exceeded for the water main. Please show the locations of all bends, and the magnitude of the bend.
|
|
|
Corrective Action Required
Please remove the water casing pipe detail and the trench check detail. These are not required for this project.
|
|
|
Corrective Action Required
Sheet 4: Please add a note stating the water line beneath 16th St. shall be bored. Casing is not required, however.
