Lee's Summit

Street Name Signs (Within Lee's Summit) shall include the cardinal direction (e.g. NW) per standard detail.

Street Name signs with Lee's Summit for private streets, Paragon Pkwy and River Rd, shall include the "Private Street" tag per standard detail.

WB-67 movements at the View High and Paragon roundabout, especially the northbound right movement, appears in conflict with infrastructure and or significant conflict with traffic in adjacent lanes for the movement to occur. As shown utilitzing the entire pavement area of the roundabout and portion of truck apron to complete the turn, there's still some overlap with infrastructure on splitter islands/medians which are not the same as truck aprons. Additional truck lane use signing and/or signed truck restrictions and routing are encouraged to minimize infrastructure damage and improve safety with truck operations if design alternatives are not possible considering the noted design constraints of adjacent bridge precluding a larger roundabout and curb return radii.

Roundabout Design information (Speed Check) was submitted for one of three roundabouts. Other roundabout design information should be submitted. Although the design table report indicates acceptable design, there were a few design concerns to note: Several entry speeds were in excess of the design speed and had more than a 12 mph deviation from circulating speed. This may indicate a larger roundabout is needed and/or more entry deflection for certain approaches.

The crosswalk on Paragon Parkway at the View High roundabout appears too close to the circulating lane and yield line for a single vehicle to queue without conflict. Can this crosswalk be moved towards the east to create sufficient separation to minimize pedestrian and vehicle conflicts. Though on private roadways, similar crosswalk separation recommendations should be reviewed at the other roundabout crosswalk locations.

The SE corner of the View High roundabout may need a larger radius. The WB-67 could not make the right turn and WB-40 required all lanes for the movement. It's likely trucks will try the movement from the right-turn lane and overrun the curb and roadside areas. If the radius cannot be increased, consider truck restrictions on Paragon Pkwy. A truck apparently cannot make the turn from eastbound View High Pkwy to southbound River Road. Consider a larger roundabout radius, curb return radius or modifications to the south splitter island.

Marking and Signing notes pertaining to jurisdictional standards may include information that advises View High Drive, though portions within City of Lee's Summit, are maintained by KCMO by executed agreement and in such case the KCMO standards/specifications should be followed.

Sheet 9: Refer to Sheet 21 for the ADA-accessible sidewalk ramp details for the ramps located at the Sta. 28+75 View High parkway.

Sheet 15: Please label the dashed line shown parallel to the proposed private water line approximate stations 0+90 to 2+30.

Sheet 21: Many aspects of the ADA-accessible sidewalk ramp design do not meet City requirements. Please review Section 5304.8 and Table LS-5 in the Design and Construction Manual and revise to meet those requirements.

Proposed grading on Sheet 23 near Bore B-103, Sheet 25 near Bores B-11 & B-14 extends beyond the Limits of Disturbance boundary.

Sheet 25: It appears that there are some kind of limits, as well as proposed sidewalk, associated with other projects shown dark as if included in this project near the River Road & Paragon Pkwy roundabout. Please clarify.

Sheets 33-34: Please revise Lines 500 & 600 as needed so the design HGL is within the pipe.

Sheet 1: • KCP&L is now Evergy. Please update the plan set. • Remove the approval signature block for the City. A stamp will be provided electronically when approved.

Sheet 2: Also reference the CLOMR as a part of the FEMA Floodplain information.

Sheet 3: Since the referenced items have been issued, should Permitting Notes 13 & 14 be revised or deleted?

Sheet 4: Revise both the pavement and sidewalk aggregate base labels to more closely match City terminology.

Sheet 5: • Revise the sidewalk aggregate base label to more closely match City terminology. • Relocate the Typical Section River Road asphalt base label for clarity.

Sheet 7: • Structure 4001 does not meet the minimum allowed inside “L” dimension as shown in the standard detail. Please revise. • Label the street name west of the roundabout. • Consider rotating the Plan view 180 degrees for easier referencing.

Sheet 8: • Relocate the proposed retaining wall located between View High Drive and View High Pkwy. Retaining walls are not allowed within public right-of-way. • Retaining walls are not allowed over public storm sewer. Structure 204A and the pipe between Structures 204A and 204 shall be private. Please clearly label as such where appropriate throughout the plan set. • Please bring “View High Parkway” to the front, or top, layer in the Profile view. Review the entire plan set to ensure the information is presented clearly. When layers are out of order, text can become very difficult to read.

Sheet 9: • The standard pavement section for View High Parkway, on Sheet 4, stops at Sta. 24+19. There is no standard section provided for Sta. 24+19 to Sta. 29+07.30. Please revise. • Since Structure 501A is being constructed over an existing storm sewer line, should this be labeled as a Doghouse structure?

Sheet 15: • Label the streets. • Please label the dashed line along the water line south of the roundabout. • Design and Construction Manual Section 6901.D.1.d.i.(b) requires 5’ clearance between water mains and storm sewer structures. • What is the end section shown just north of the water line at approximate Sta. 8+00? • Include the following note on any profile sheet applicable: “Compacted Fill shall be placed to a minimum 18” above the top of the pipe prior to installation.” • Show and label the limits of the compacted fill placement in the Profile view. Use hatching for clarity. • Adjust the Final Grade leader arrow to point to the grade line.

Sheet 16: Revise the material type in the “Construct 8”…” label in the Profile view.

Sheet 17: Consider removing information not pertinent to this exhibit for clarity. Items such as existing plat labels, boring hole locations, ownership and zoning information, parking lot striping are all the types of items that help make this sheet very crowded and more difficult to read.

Sheets 18-20: The Intersection Detail Legend doesn’t include all of the sidewalk ramps, the labels don’t make sense, and only one of the numbers (4) is shown in the Plan view.

Sheet 20: Adjust the Proposed Waterline leader to point to the water line.

Sheet 21: The specific details of all ADA-accessible sidewalk ramps must include, at a minimum, the design details specified in Section 5304.8 of the Design and Construction Manual. Elevation call-outs, although required, are not sufficient. Other design details specified in this section are required, including slope call-outs which comply with the criteria listed in Table LS-5, and section views specified in 5304.8.

Sheets 22-25: • Please review the grading sheets to ensure all proposed contours tie back into existing contours. • Revise proposed contours to be only within the Limits of Disturbance boundary. • Include TW & BW wall elevations on the grading sheets in order to verify the proposed wall elevations make sense.

Sheets 26-28: Please either refer to project phases or stages, don’t mix the two.

Sheets 29-30: Include APWA inlet protection standard details.

Sheets 33-34: • Review all text line weight for consistency. Revise as needed. • Relocate any connection numbers that overlap other text for clarity. • The grid used on these Profile sheets make the information very hard to read. Please only provide stationing grid lines every 25 feet for clarity. • Please review profiles to ensure all grade lines are correctly labeled and are of consistent line types. • Please label or remove the double lines shown between Structures 203 & 205. • Please review the Line 200 10-yr HGL and revise as needed. • APWA 5600 requires Collector roadway crossings to convey the 4%, or 25-year, storm event. Please ensure this requirement is being met and include the 25-year HGL in Profiles as appropriate.

Submit an Engineer's Estimate of Probable Construction Costs.

All review comments from 2/11/19 need to be referenced; none appear to be addressed. A majority of those comments are supplemental calculations and plans that need to be submitted in support of the design for the project record (e.g. vehicular turning movements at the roundabout, roundabout design speeds, sight distance illustrations at the roundabouts, lighting design calculations). This supplemental information is typically not included in the plans, but submitted separately for review concurrently with the plan set. Several other comments pertained to receipt of KCMO approvals for various plan elements to include in the project file (e.g. Marking/Signing, Lighting and TTC on View High Drive/Roundabout). All prior comments should be checked and addressed.

Plan review will be completed upon receipt of the requested design information. Additional comments may or may not be forthcoming.

For each roundabout, submit a tabulation of design speeds calculated for each of the curves to include approach, curve, radius, circulation, exit, speed and speed differential of all movements at all legs of the roundabout. See Roundabout Design Criteria Table in the DCM for typical design speeds and information required for review.

For each roundabout, submit drawings illustrating that design vehicle(s) can be accommodated for all movements at all legs of the roundabout. The vehicle path shall maintain a minimum 2- foot clearance between the tire track and the curb. Drawings shall be submitted illustrating each vehicle path and per design vehicle (e.g. P, SU, WB).

Additional review comments are pending further review dependent upon direction and decisions from KCMO regarding ownership and standards for View High Drive and View High Parkway. I assume KCMO will also review and approve these roadway plans, including marking, signing, and lighting in coordination with Lee's Summit; especially for View High Drive and View High Parkway.

Drawings that illustrate the intersection and stopping sight distances within, approaching and departing the roundabout need to be submitted for each roundabout for staff to review in reference to monument signing and any other potential landscape obstruction proposed within or adjacent to the roundabouts.

Lighting is assumed private along View High Drive, View High Parkway and River Road...The lighting will need to be included in the maintenance agreement(s). What standards and specifications are the lighting designed to meet; KCMO or LSMO? How are the proposed lights on View High Drive powered and controlled? Provide a table of lighting design calculations, avg. illuminace, avg. to min. ratios, circuit loading, voltage drops, etc. for each system.

Revisions to shown ROW and shown easements are pending decisions of ownership.

Pavement Marking along View High Drive and within the View High Drive roundabout should meet the requirements of KCMO and MUTCD. KCMO plan approval should be sent to LSMO for record.

Signing along View High Drive and within the View High Drive roundabout should meet the requirements of KCMO and MUTCD. KCMO plan approval should be sent to LSMO for record.

Signing: a.) Advance warning signs and advisory speed signs for the roundabouts are missing. b) The roundabouts should include street name signs. Marking: c) Note the materials for marking symbols (including stop lines, yield lines, diagonals, arrows, crosswalk lines) and longitudinal lines; LS requires preformed thermoplastic and high-build paint, respectively.

Signing and Marking along View High Parkway is pending deterimination of ownership, but shall comply with the standards and specifications of KCMO and/or LSMO, as applicable, and the MUTCD.

The TTC and Detour Plan needs to be reviewed by KCMO and approved. MoDOT permitting will be required for the Detour Route. Submit KCMO approvals as applicable.
