Lee's Summit

Sheet 2: Please revise the typical pavement section to be complete and to be for this project.

Sheet 4: • Rip Rap Pad A is shown to be 2.22 CY, but the dimensions shown actually calculate to 2.67 CY. Revise as needed. • The note below the Lot Corner Elevation and MBOE table states that the “MBOE is based on being 2’ minimum above the highest back corner or 2’ above the maximum WSE for a walkout basement” which Lot 6 has. The highest back corner is 1021.0 and the maximum WSE is 1017.0. The left rear proposed elevation is 1001.5. The left rear MBOE of 1001.5 does not appear to meet either requirement shown. Please review and revise as needed.

Engineer’s Estimate of Probable Construction Costs: • Items for Temporary Construction Entrance and Outlet Protection are not included in the estimate. Please verify all required items of work on the project are included. • Item Nos. 8 and 20 are both rip rap, but different sizes. It appears that Item No. 8 refers to Rip Rap Pad A, although the quantity doesn’t match the plans or the calculated quantity. Item No. 20 doesn’t appear to be in the plan set. Please verify these items and revise as required. • Item No. 24, Inlet Protection, has a quantity of 600 but should be a quantity of 1. Please revise. Prior to resubmittal, please review the estimate for correctness. Being off by $300,000 on a project of this scope is something that I would expect to be caught prior to submittal for review.

Sheet 2: Include a full width pavement section.

Sheet 3: Please revise “Controlled Fill” to “Compacted Fill” in the Profile view.

Sheet 4: • Please include all Pre/Post lot corner elevations and 100-yr WSEs on this sheet, not Sheet 7. Include elevations for the NE corner of Lot 8, they were omitted on Sheet 7. • Remove Erosion Control from the title block. • The Lot 6 Rear Left Corner MBOU includes a typo. Please revise.

Sheet 5: Remove everything except Erosion Control in the title block.

Sheet 6: Drainage Area labels are blurry and difficult to read. Please revise for clarity.

Estimate: • The Asphalt quantity should be less than the crushed stone & geogrid quantities since the asphalt doesn’t extend as far as they do, Please revise accordingly. • Review quantities for Items 6-8, 10, 12, 15, and 18. Revise as needed. • Add items for FES, Bends w/Thrusting Blocks, and Inlet Protection. • What is Item 20 in the plan set?

Storm Water Drainage Report: • The Section 3 narrative indicates the site is 10.18 acres, and the Section 4 narrative indicates the existing pond is 3.3 acres. That is a difference of 6.88 acres. However, the rest of the report , as well as the plan set, indicates a 7.03 acre site. Please reconcile. • Please include Q2 and Q(allowable) in the Section 4 tables. • Include data and discussion regarding the Water Quality requirements.

General: • Submit a Stormwater Report for the proposed design. • Include a Master Drainage Plan showing existing and proposed elevation at all property corners as well as 100-yr WSE at all property corners adjacent to Tract A. • Separate the Erosion and Sediment Control plan onto separate sheets depicting all stages (before, during, after) of construction. • Include a note stating that the ADA sidewalk ramp shall be constructed with the public infrastructure. • Label Tract A throughout the plan set. • Label all easements throughout the plan set. • Submit an Engineer’s Estimate of Probable Construction Costs. • Submit the SWPPP.

Sheet 1: • Revise General Note 3 to refer to Development Engineering Inspections at 816-969-1200.

Sheet 2: • Show and label the 100-yr WSE on this sheet and throughout the plan set.

Sheet 2: • Sidewalk details are included on this sheet and Sheet 4. Please only include once. • A detail of the ADA ramp is included on this sheet showing widths and Sheet 4 showing some of the required design information. If including on both sheets, please include a callout throughout the plan set referring to the sheet with the complete design information.

Sheet 3: • Sanitary Sewer Note 7 conflicts with the “Controlled Fill” note. • Sanitary Sewer Note 13 references a swale. Where is the swale located? • MH A4 FL(Out) info doesn’t match between Plan and Profile views. Please reconcile.

Sheet 4: • Clarify the Storm Sewer Notes to indicate that the inspections will be done by Development Engineering Inspection. • ADA Sidewalk Ramp Detail must include dimensions as well as slopes. Include spot elevations at each corner of each sidewalk section. • Is Rip Rap Pad A temporary or permanent? If permanent, include design information to verify the rip rap design isadequate. • The Lot 7 MBOE has an asterisk in the table, so please use the same symbol for the referenced note below. • Lots adjacent to Tract A will have MBOEs set a minimum of 2’ above 100-yr WSE.

Sheets 5 & 6: • The existing and proposed drainage area maps should clearly delineate each drainage area onsite and include offsite portions if the areas extend beyond the property line. Enough offsite information should be included to allow an overall understanding of how the project will impact the adjacent properties. Care should be taken in areas where there are existing trees along the property line to correctly show how the drainage actually flows in both existing and proposed conditions due to the possibility of the tree line actually forming a slight berm to redirect flows.

Sheet 7: • Revise the water line size to 6” as it connects to an existing 6” line and is part of a dead end main that will not be extended in the future. Revise throughout the plan set. • Include the sanitary sewer service lines in Plan view, scaled back like the sanitary sewer main is shown. • Revise the two labels near Sta. 1+50 in the Profile view for clarity. • Revise Note 14 to refer to the Design and Construction Manual.
