As previously stated, the 100-year WSE must be a minimum of 20’ from any building or property line. The revised location meets that requirement from the property line, but does not appear to be 20’ from the building. Please revise.

Parking lot pavement sections are specified in UDO Section 8.620, not Design and Construction Manual Section 5200. The proposed sections exceed City requirements. They are acceptable, but not required. If the intent would be to revise to City equirements during construction, please note that a submittal will be required for review and approval. In that case, it would be better to make the revision now rather than later.

Sheet C7.1: Revise "X" to the correct size in the B1 label in the Structure Table.

Estimate – Add the following items • Scour Stop • Junction Box 4’ x 4’ • Grate Inlet 4’ x 4’ • Connection to Existing Storm Sewer Estimate – Check and revise the following items if needed: • 6” (estimate) vs. 8” (plans) size of roof drain HDPE • Sizes and quantities of End Sections, plans and estimate do not match • 2” C901 quantity, plans and estimate do not match • Backflow Preventer unit price, typical unit prices range from $12,000 to $18,000 each

General: • Submit an Engineer's Estimate of Probable Construction Costs. • Submit the SWPPP and a copy of the MDNR Land Disturbance Permit. • Include a cover sheet with the following information: o Project title. o Vicinity map. o Developer’s name, address, phone number, and email address. o Utility contact information. • Show and label the 100-year WSE throughout the plan set. • Remove the existing driveway curb that is being demolished from the proposed views throughout the plan set. • Remove the property line along the east edge of the building, as it will be removed in the platting process. • Clearly show and label all easements throughout the plan set.

Sheet C1.0: • Please revise all specification references to only the City of Lee’s Summit. Any APWA specifications are a part of City specifications by reference. • Please revise General Utility Note 14 to reference the correct city.

Sheet C2.0: Keynote 08 is used 3 times. Please revise.

Sheet C3.0: • Please revise the pavement hatching in the Legend to visually match the Plan view. • Keynote 13 indicates a 6” berm will keep drainage from the east off of the site by diverting it around the site. If this berm is intended to be within the property boundary, as it appears, then please account for this drainage area in the stormwater report and the drainage map. By diverting along a berm, sheet flow will be converted to concentrated flow. Provide calculations showing shear strength requirements for this concentrated flow will be met in order to keep erosion from occurring. Provide a detail of the required berm section. • Lee’s Summit refers to curb and gutter as CG-1 or CG-2. Please revise Type B to match the City’s designation as shown in the standard detail.

Sheets C4.0-C4.1: No keynotes are used, so please remove the keynote legend.

Sheets C5.0-C5.1: • Revise overlapping text for clarity, such as east of the entrance and west of the handicap parking. • All proposed contours need to tie back to existing contours. Please review and revise as needed. • A 2% minimum slope is required for the bottom of the detention basin. Please verify this requirement is being met. • Include some type of reference to know where Grading Details A-E, as shown on the following 2 sheets, are located.

Sheets C5.2-C5.3: • Detectable warnings are not required for ADA-accessible ramps at entrances. Please remove. • Please check the scale for Grading Detail C. Revise if needed. • Please review the criteria listed in Table LS-5, and section views specified in 5304.8 in Section 5304.8 of the Design and Construction Manual and include all required information. This includes slopes and lengths of each edge of all sections. • A turning space is required where the private sidewalk connects to the public sidewalk.

Sheet C6.0: • The backflow vault needs to be located outside the public right-of-way and easements. Platting will require a 10’ utility easement be located along the Colbern Road frontage. Please locate the vault beyond the easement. • The backflow vault is a part of the private fire line, so it does not get placed within an easement. Please remove the proposed utility easement shown around the vault location. • Show and label the water meter. Is this the existing water meter and location, or proposed? • Label the sanitary connection as a cut-out wye. • Roof drains labeled ST-5 are not shown draining to the detention basin elsewhere in the plans and roof drains labeled ST-6 don’t drain to the detention basin as labeled. Please revise.

Sheet C7.0: • Show the existing pipe flowline information at Structure A1 in the Storm Line A Profile view. Is the proposed MH a “Doghouse” MH? If so, please label as such. • Relocate overlapping text in the Storm Line A Profile view for clarity. • A 0.5’ drop between the proposed and existing pipe at Structure A1 is required. This information will be checked when the existing pipe flowline is provided. • There appears to be an extra section of pipe, end section, and B1 label in the Plan view. Please remove on this sheet and all other sheets it appears. • The APWA/MARC BMP Manual Section 8.10.5 requires that consideration be given to locating the basin outlet as far away from the basin inlet as possible to prevent water from short-circuiting the facility. The proposed locations are both located at the south end of the basin only 20’ apart. It appears that it is feasible to locate the inlet and outlet a greater distance apart. Please revise or provide an explanation as to why it isn’t possible. • In the Structures Information Table description for Structure A3, please refer to the sheet containing the outflow structure design information. • Where invert elevations both in and out of a structure are provided in Profile view, make sure they correspond to the flow direction. • Other plan sheets indicate that there is a pipe and end section upstream of Structure A3. Please revise accordingly.

Sheet C7.1: • Remove the extra B3 label in the Plan view. • Where invert elevations both in and out of a structure are provided in Profile view, make sure they correspond to the flow direction. • Show Structure B1 as an end section in the Profile view. • Please “X” with the proposed size in the Structures Information Table description for Structure B1. • It would appear that rip-rap or some other erosion prevention is required at Structure B1. Please provide calculations to show the design of the proposed area is adequate for the outlet flows and velocities expected. • Profiles are required for all pipes greater than 6” diameter. If the proposed roof drains are 12” diameter, as shown elsewhere in the plans, please include pipe profiles. • Include flowline information at any connections between roof drains and storm sewer.

Sheet C10.0: The pavement sections don’t meet City requirements. Some exceed, which is fine, but didn’t want that to cause a problem during construction. Some don’t meet requirements, and need revised. Please refer to City requirements and revise as needed.

Sheet C10.6: • The Control Structure elevations don’t match the Final Stormwater Management Study. Please • Required freeboard has not been provided. Please revise. • The 11” weir opening dimension shown on Section A-A overlaps with the centerline graphically. Please adjust for clarity.

Final Stormwater Management Study • The report is missing extensive information. Please refer to the City’s Stormwater Report Requirements , available on the City’s website, for a list of information required. See also the report recently approved for the MCPL – East Lee’s Summit Library Final Development Plan as it contained the required information. • The first two sections of the report indicate the existing library will remain. Please revise. • The Outfall A section of the Proposed Conditions Analysis indicates all impervious areas drain to the detention basin. Part of the impervious area will drain undetained to Colbern Road. Please revise. • The Conclusion and Recommendations section refer to “detention basins” in the plural. Please revise for clarity as there is only one detention basin proposed. • A complete review of the study will be performed when complete design calculations have been submitted.
