Miscellaneous Correction

After email conversations with staff and the developer, it has been agreed that a design for a 3-legged intersection will be sufficient submittal for permit. The design must accomodate the improvements required by Ovation so that none of the equipment will need to be moved at a later date.

Misc

Traffic staff gives conditional approval of the Public Infrastructure plans. MoDOT approval of the plans for the signal at the intersection of MO 150 and Sunset Ridge Drive will be required before any substantial completion will be allowed on the project.

Misc

Improvements along 150 HWY should be included with this submittal. MoDOT will have to give final approval but the staff will need to review as well. Staff is in discussions with MODOT about how to procees with the traffic signal required at Sunset Ridge. Final approval will not be given before MoDOT advises how to proceed.

Miscellaneous Correction

The merge lane for northbound traffic seems unnecessary. A single lane with a wider island may be a better fit. Striping for the extra widening should be yellow if on the lfet hand side of the roadway.

Miscellaneous Correction

Staff has spoken with MoDOT about the planned signal at Sunset Ridge and it has been determined that the signal will be required before occupancy of the project. Plans should be submitted to MoDOT for review and approval must be given to the City before approval is given on these plans with the understanding that construction is not required until a later time.

Miscellaneous Correction

An MDNR permit shall be required for this project. Informational comment.

Miscellaneous Correction

Miscellaneous Correction

Additional fire hydrant is required on Fern Ln. to the south of 26th St. Correction required.

Miscellaneous Correction

MDNR construction permit shall be required prior to formal approval. Informational comment.

Miscellaneous Correction

S denotes "slab" basement on the Master Drainage Plan. Is this what you intend? Assuming you wish to change this designation to represent a "standard" basement. Informational comment, and corrections required if appropriate. Otherwise, only slab on grade homes will be allowed without special permission from the designer.

Miscellaneous Correction

Cost estimate required prior to formal approval. Informational comment.

Miscellaneous Correction

Sheet C201: Change Line 2-FF to “PROP 12” WATER". Correction required.

Miscellaneous Correction

Sheet C202: The limits of the casing pipe appear to extend to the 12” water main running along HWY 150 at Sta. 1+15.00. The casing pipe should start north of the butterfly valve. Correction required.

Miscellaneous Correction

Sheet C202: Three (3) valves are required at all tees. There should be three valves installed at the tee at Sta. 1+00. Correction required.

Miscellaneous Correction

Sheet C204: Why move the 12” water main to the west side of Sunset Ridge? There is room to place the 12” water main in the 15’ UE on the east side of Sunset Ridge, and avoids jogs and reducers. Correction required.

Miscellaneous Correction

Overview Sheet: Label all street names on overview sheet. Correction required.

Miscellaneous Correction

Overview Sheet C201: Line FF is mislabeled as an 8 inch line. This should be a 12 inch line. Correction required.

Miscellaneous Correction

Sheet C202: Gate valves are desired for 12 inch lines. Butterfly valves should only be used for valves larger than 12 inch. Correction required.

Miscellaneous Correction

An MDNR permit shall be required prior to formal approval. Informational comment.

Miscellaneous Correction

Label all street names on the general overview sheet. Correction required.

Miscellaneous Correction

Please label existing manholes with the official City manhole number. Connection point of line D is 58-063. Line H is 58-067. Line B is 58-051. Correction required.

Miscellaneous Correction

Relocate manhole H-3 to not exceed 400 feet in length from the next manhole H-4. Correction required.

Miscellaneous Correction

Eliminate manhole H-2 and direct connect to existing City manhole 58-067. Correction required.

Miscellaneous Correction

Line B appears to be located in an easement that is too narrow. Required width is twice the depth assuming the line is centered within the easement. Correction required on plans and plat.

Miscellaneous Correction

An MDNR permit shall be required for this project. Informational comment.

Miscellaneous Correction

Stormwater manhole lid shall meet new requirement for lettering. Standard detail to be sent separate from this applicant letter. Corrections required.

Miscellaneous Correction

Sheet C051: All asphaltic concrete to be KCMMB mix. Correction required.

Miscellaneous Correction

Typical Pavement Section Views: Recommend a re-review by the engineer for the most up-to-date design criteria for residential local access, and residential collector. Design criteria is shown on Table LS-2 of the most up-to-date version of the table within Section 5200 of the Lee's Summit Design and Construction Manual. Some criteria became less stringent, others more. Most changes are related to aggregate thickness, which mostly were decreased from the past version of the Design and Construction Manual. Correction required.

Miscellaneous Correction

Recommend removing the light blue, blue, and purple phasing lines from Sheet C101. These plans are for Cobey Creek 2nd Plat, and Sheet C101 should concentrate on the 2nd plat/phase rather than showing the entire phasing of the project. Recommend "graying-out". Correction required.

Miscellaneous Correction

S denotes "slab" basement on the Master Drainage Plan. Is this what you intend? Assuming you wish to change this designation to represent a "standard" basement. Informational comment, and corrections required if appropriate. Otherwise, only slab on grade homes will be allowed without special permission from the designer.

Miscellaneous Correction

Sheet C501: A cross-hatched area representing what is shown in the legend to be a drainage swale does not appear to make sense. Correction required.

Miscellaneous Correction

Offsite existing elevation contours shown on Sheet C104 do not appear to match what is shown on Sheet C500 "Inlet Drainage Area". Reviewing Sheet C500, it would appear additional inlets and pipe are needed. Reviewing other sheets, it would appear this is not necessary. Evaluate and correct if necessary.

Miscellaneous Correction

There are mid-block crossings shown on the plans with 1.5% maximum cross-slope callouts. This may introduce a bump in the road, and is not desired. Mid-block crossings can match existing grade as long as the running slope does not exceed 5%. Evaluate and revise as appropriate.

Miscellaneous Correction

The existing north detention basin shall include a detailed design showing how the basin will be converted to a sediment basin. This shall include any skimmer(s) to be installed, sizing of the skimmers, installation of the skimmers, block-offs of the existing outlet structure water quality orifices, etc. Correction required.

Miscellaneous Correction

A note shall be provided on the erosion and sediment control plan in bold lettering that states "SEDIMENT BASIN CONVERSION TO OCCUR PRIOR TO ANY CONSTRUCTION ACTIVITIES" or equivalent language. Correction required.

Miscellaneous Correction

Miscellaneous Correction

Sheet C401: The truncated domes on bottom right exceed the maximum 5.0 feet distance to back of curb. Correction required.

Miscellaneous Correction

ADA-accessible routes across intersections: Ensure non-stop controlled intersections match road grade (max 5%) to eliminate any bump (i.e., change in grade) at the non-stop controlled intersection. It appears all ADA-accessible routes across intersections were designed with 1.5% cross-slope, which is not desireable for non-stop controlled intersections. Correction required.

Miscellaneous Correction

Many of the notes for the ADA-accessible routes across streets and intersections state "5.00 ft. max". This should be called out as 5.00 feet, not "max". Correction required.
