Miscellaneous Correction

Specify type/size of all water service connections. 9/20/2024 - Type of connection not provided.

Miscellaneous Correction

Specify locations, types, size, etc. for water meters. ** Notes: - Meters larger than 2" require custom designed pits. - Water meter detail shown is for maximum 2" meter. - Water Department dictates size and material of all piping from main to 10' past meter. 9/20/2024 - Water pipe from main to meter and then minimum 10' past meter is required to be 2"

Code Statement

All issues pertaining to life safety and property protection from the hazards of fire, explosion or dangerous conditions in new and existing buildings, structures and premises, and to the safety to fire fighters and emergency responders during emergency operations, shall be in accordance with the 2018 International Fire Code.

Water Supply

IFC 507.1 - An approved water supply capable of supplying the required fire flow for fire protection shall be provided to premises upon which facilities, buildings or portions of buildings are hereafter constructed or moved into or within the jurisdiction. Confirm construction type. The fire model must provide the needed fire flow required by IFC Table B105.1(2), with 50% reduction for a sprinkler system for either a VA or VB building? Calculated on the largest building at 79, 582 sq. ft. 12/9/2025- V-A Construction acknowledged along with 2,500GPM fire flow.

Sanitary sewer service line connection to an existing main must be made with a cut-in wye. Please label the connections for Buildings 1, 3, and 5 accordingly.

As shown, the detention basin extends into the public easement located to the west. Moving the proposed water main removed that issue, but the basin still encroaches into the public easement around the sanitary sewer main.

The ESC plans don’t include a sediment basin. This site would seem to need one to adequately control sediment leaving the site. We typically see the detention basin being used as a temporary sediment basin since it’s normally located in the lowest area. Please either add or explain. If added, be sure to include all appropriate standard details.

Please remove City Standard Details GEN-5, GEN-6, and SAN-4 as they aren’t used in this project.

Please add all City Standard Water Details.

Provide a backfill detail.

Sheet C02 - remove the boundary of the previously vacated right-of-way.

Sheet C04 - update the spelling of "ratio" and change "proposed zoning" to "existing zoning."

Sheets C11, C12, and C13 - Provide setbacks to the parking lot from the applicable property lines.

Sheet C13 - setback for building 7 should be measured to the closest point.

Update the landscaping count - the open yard area includes the detention area for the tree requirement. The latest revisions updated the count for shrubs but not for trees.

Sheet L1.00 - provide greater contrast between the tree symbols and the lawn so staff can confirm the landscaping requirements are being met.

The total percentage of open space needs to be stated. If it is already on the plan set, please let me know where.

Photometric - confirm the concrete base/pedestal height.

Photometric - show the perimeter area (100-ft. inset from the property lines).

Sheet C06 - there is a building setback line called out at 18.9', but then the dimensioned setback is at 20.1' and they appear to be at the same location. Remove any unnecessary dimensions and verify setbacks.

Provide setbacks to the buildings as well as the balconies.

Many of the parking stall dimensions include the curb and gutter which we do not allow per Section 8.620 (https://library.municode.com/mo/lee's_summit/codes/unified_development_ordinance?nodeId=ART8SIST_DIVIIPA_S8.620PALODE). The project was previously approved a modification to allow 157 compact spaces, any additional spaces that do not meet the required 9' in width by 19' in length must either be removed or the site needs to be adjust to meet that requirement without including any of the curb.

General: • These comments are in addition to, or sometimes a repeat of, our phone discussion last week. • Please note that complete review of the grading and storm sewer system has not been completed. This will be done when the plans are more legible. • Please include a roof drain plan and profiles for all pipes greater than 6” diameter.

Sheet C03: As previously requested: • As discussed, please look to ways to make the plans easier to read. As is, many sheets are very difficult to read. • Please refer to Development Services, 816-969-1200, and not Public Works in Layout & Paving Note 6. • Please refer to City of Lee's Summit and not Board of Public Utilities in Site Utility Note 6. • Please refer to Design and Construction Manual and not Technical Provisions & Standard Drawings for Roads and Sewers in General Note 1 and Erosion Control Notes 1 & 2.

Sheet C04: • Please make a “typical” label for the proposed public water and sanitary sewer mains and refer to them as public and by others, or similar. There can just be 1 or 2 labels shown as typical. • Please coordinate the proposed public sanitary layout with different sheets in this plan set so they all show the same information. • Please show construction of the drive approaches and associated ADA ramps with this plan set. • There appears to be missing linework on the fire line to the proposed hydrant just east of Bldg. 1. • The City requires water meters to be located in grass rather than paved areas, including sidewalk. All meter locations seem to be shown in paved areas. Please revise. • The public sanitary sewer shall terminate at Lot 3. Any line upstream of that will be private. • As stated in the previous comment letter, sanitary sewer service lines can’t connect directly to MHs. Please revise as needed. • As discussed, the detention basin must not extend into any public easement. Please revise. • Please clarify existing easements, proposed easements, and easements to be vacated. This may be done on a separate document.

Sheet C10: Please dimension the distance from the 100-yr WSE to the property line on this sheet and all other appropriate sheets.

Sheet C14: Pavement design is a requirement of plan approval. An alternate pavement design after permit issuance can be requested. Depending on the change, a waiver from the City Engineer may be required.

Sheet C21: • It would appear that rip-rap or other energy dissipation will be necessary at the end sections entering the detention basins. Please evaluate and revise as accordingly. • It appears that the water will pond at the end sections. Please evaluate and revise as necessary.

Sheets C25-C28: • The City’s design requirements for ADA-accessible ramps is 1.5% maximum cross-slope and 7.5% maximum longitudinal slope. This allows a construction tolerance. Please revise as needed. • Please ensure all crosswalk slopes are visible.

Sheet C31: Please review all of the structure and drainage area callouts. Some are missing, some are incorrect. Please revise as necessary.

Sheets C33-C35: • Please include the design HGL in Profile view. • Please include the station in the 2End callout in Plan view. • Please extend the Plan view to include Structure 2I. • Please include information for the FES and Structure 2E in Profile view. • The drop thru Structure 3A does not meet the minimum 0.5’ drop required.

General: • Submit an Engineer's Estimate of Probable Construction Costs. • Submit the SWPPP and a copy of the MDNR Land Disturbance Permit. • Please review the plans for clarity. There are many line weights, labels, text overlapping, and text box masking of information that make portions of the plans unreadable. There is also extraneous information that is crowding the page. For instance, there is survey information and shading that doesn’t need to be on every sheet. It all makes the plans very hard to read. • Show and label all existing sidewalks, including widths.

Sheet C01: Please show location of all oil/gas wells, or indicate none are present, and cite the source.

Sheet C02: The vacated Sloan Street ROW is shown, but isn’t an existing condition.

Sheet C03: • Please replace Layout & Paving Note 5 with “The contractor shall contact the City’s Development Services Engineering Inspection to schedule an inspection coordination meeting with a Field Engineering Inspector prior to any land disturbance work at (816) 969-1200.” • Do the Wetland Notes apply to this project? If not, please remove. • Please revise Grading Note 5, and Site Utility Notes 6 & 17 to reference the correct location. • Grading Note 8 and Earthwork Note 8 contradict each other. Please coordinate. • Grading Note 10 and General Note 11 are incorrect. All work within the right-of-way associated with this project is included in the site permit. It would not require a separate permit. • Please revise Site Utility Note 14, 8” and larger does not require ductile iron pipe. Please see Design and Construction manual Section 3901.B.1. C900 is preferred over DIP. • The Design and Construction Manual has separation requirements, but does not always require a change in pipe material. Please note that the City does not prefer the use of DIP in general. • Please refer to the Design and Construction Manual as the reference specification for Lee’s Summit in General Note 1 and Erosion Control Notes 1 & 2. • Please revise “2012” to “2018” in General Note 20. • Please revise “Public Works” with “Development services” in Erosion Control Note 21.

It’s fine to require more than the City does, just wanted you to be aware. • Please label structure 1G in Plan view. • Structures 3A, 5A, 5B require 0.5’ drop. Please revise. • Please move the detention basin outlet structure information to a separate Detention Basin sheet. Include the plan view of the basin, as well as a Profile for the outlet pipe. Include the basin volume required as well as the volume as designed. On Plan view, include the emergency spillway location, elevation, and length.

Sheet C36: • Please label water meter sizes. Water meters are not combined in the backflow vault. • Please clarify, are there water meters for each building or one main meter? • Service connections to the public main can only be made with a wye connection, not a connection to a MH. Please revise as needed.

Sheets C39-C47: • The method of draining the backflow vault sump shall be shown. This can be accomplished by daylighting with a small diameter pipe or connecting to a storm structure. Each option could be done with or without a sump pump, depending on grades. Please evaluate and revise as appropriate. • Provide sanitary sewer service line flowline elevation at buildings.

Grading plans show a marked crosswalk across the driveways, however they are not shown anywhere else on the site plans. Staff does not feel a marked crosswalk is needed and they should be removed.
