Sanitary Sewer The proposed sanitary sewer manhole does not have the minimum clearance of 15' from the drainage basin walls. This encroachment would require a waiver request. In order for a waiver to be considered by the Engineering Manager and the Deputy Director of Water Utilities, you must submit - The completed template (DCM Design Criteria Modification Request). - A signed and sealed summary of the request waiver, including the DCM citations that you are requesting be waived. - Exhibit(s) showing, in general, where it is located. The proposed public sanitary sewer main extension does require separate plans be submitted. These may be added to the public water main extension plans for this project. Please note that there is ongoing discussion with Water Utilities to verify that the existing sanitary stub is in adequate condition for your proposed connection. A camera study is being performed and the results will be forwarded.

Stormwater Study - This is not a preliminary report. It should be a Final Stormwater Stormwater report, not a preliminary report. - It does not appear 40 hour extended detention was discussed in the report, nor designed as part of the basin. - If not doing 40 hour extended detention, other volumetric controls can be done on-site, but shall be clearly shown where and how. - There does not appear to be any specific design of the outlet structure in the plans to support what is shown in the study. - The emergency spillway is not designed correctly. The bigger question is whether an emergency spillway is required due to the fact it is within a depression, and overflow will not create a life safety or property damage issue. - No further review can be performed until a complete Final Stormwater Report has been submitted.

BUILDING MATERIALS. - The proposed polycarbonate material to be used for the building is not a material explicitly listed under the approved materials listed under UDO Section 8.170.A, 8.170.B, and 8.170.C and thus shall require going through a 3-month public hearing process before the Planning Commission and City Council for consideration of its usage. Should this be required, the materials request will need to be done under separate preliminary development plan application. - Quantify and list the percentage that the polycarbonate material makes up of the respective facade on which it is used. - Should the applicant decide to proceed with the process to obtain approval of the use of polycarbonate from the Planning Commission and City Council under separate preliminary development plan application, provide a copy of the maintenance/replacement program for the use of the material in its proposed application for a car wash.

TRASH ENCLOSURE. Provide clarity as to the material to be used for the proposed trash enclosure walls. The detail on Sheet MW-9.4 shows the use of two types of EIFS with different profiles, but it provides no further information regarding what the enclosure's structural walls will be constructed of. The City's UDO requires that enclosure walls be constructed in masonry. An EIFS exterior can be installed over the masonry walls to suit a certain design aesthetic, but the underlying structure must be of masonry construction.

SIGNAGE. The City's sign ordinance allows a maximum of two (2) wall signs by right for any building located in the PI (Planned Industrial) zoning district. The elevations appear to show a total of six (6) signs. Revise.

Wher is the fire hydrant in the west driveway being relocated to?

Curb returns are shown as 25'. The minimum radii for commercial is 35'.

The dumpster doesn't appear to be in a great spot. They are not allowed to use the R/W to turn vehicles around, this must be done on the site. Provide verification that the trash truck can turn around on site. This also will conflict with entering and exiting vehicles unless trash pickup is done before opening.

Page 4: Shows a passenger truck entering from the north and the vehicle tracking only leaves about 8' for an exiting vehicle to pass by. This is very tight and should be looked at.

What is the purpose of the gate right before the building? If this is for vehicles that change their mind to exit without entering the car wash, will it be remote access by the cashier or will an attendant need to let them out manually?

BUILDING MATERIALS • For ease of reference and clarity as to the proposed exterior building materials, provide an exterior building material legend/schedule on Sheet MW-4.1. • Label the proposed exterior building material colors on Sheet MW-4.1. • Label what appears to be a gray, vertical corrugated material shown above the glazing on both the north and south elevations. • The use of any exterior building material not explicitly listed under the approved materials listed under UDO Section 8.170.A, 8.170.B, and 8.170.C shall require going through a 3-month public hearing process before the Planning Commission and City Council for consideration of its usage. Should this be required, the materials request will need to be done under separate preliminary development plan application.

Sheet C200 – In the site data table please include the below information • Total area of land in square feet and acres • Total floor area (unsure if the 5,235 sq. ft. is floor area or foot print) • Floor Area Ratio (FAR)

Sheet C200 –The proposed curbing for the drive aisle along the south property line is encroaching into the required 20’ parking lot setback adjacent to Thompson Dr. Please adjust the location to meet the UDO minimum parking lot setback requirements.

Please show the location of all of all oil and/or gas wells within the subject property. If none are present please add a note stating so and cite your source of information.

Please provide details for the material to be used in all proposed retaining walls.

Will there be any wall mounted lighting fixtures? If so please provide the manufacturer’s specification sheets for proposed exterior lighting. The specification sheets shall indicate the exact fixture to be used.

Will there be any ground mounted mechanical equipment? If so please show the location, size, and type of material to be used in all screening of ground mounted mechanical equipment. Also provide the manufacturer’s specification sheets for proposed mechanical equipment to be used.

Will there be any roof mounted mechanical equipment? If so please show the location, size and materials to be used in all screening of rooftop mechanical equipment. On the elevations, please show a dashed line indicating the roof line and rooftop mechanical equipment.

1 tree shall be planted for each 30 feet of street frontage. Any deviation from this requirement will require approval by the City Council during the PDP process. As proposed you are not meeting the street tree requirement along M 291 and Thompson Dr. The planting of ornamental trees in a U/E is acceptable. Such trees may be clustered or arranged within the setback to meet the UDO requirements.

Please show the location of any proposed trash enclosures and provide a detailed drawing of the proposed enclosure and any screening methods to be used in connection with trash storage containers.

The use of curb blocks in parking areas is prohibited, except at the head of accessible parking spaces when they are adjacent to a pedestrian walkway with no raised curb. There looks to be curb block adjacent to the ADA aisle in a non-ADA stall.

Sheet C200 – Please label the width of the proposed ADA parking aisle.

Sheet C200 – The propose curbing looks to block the ADA path from the parking stall to the building. Please update this to show a curb type that will allow a clear ADA path.

General - Please provide Engineer’s Estimate of Probable Costs. - Please provide MDNR Land Disturbance Permit and SWPPP. - Revise these plans with any revisions to the Water Main Extension plans.

C200 - Please show and label right of way and easements within the project area. - For the new commercial driveway, please show limits on the plan and call out 8” thick KCMMB concrete from the radius return to the right of way line.

C400 - W2 appears to be mis-located and does not point to the water meter. - Is W3 also a water meter? If so all water meters should be located together. - There appears to be a conflict with a fire hydrant within the paving for carwash circulation. Evaluate this and the need for additional fire hydrants on the proposed water main extension.

C501/502 - Please add a note for the compacted fill, indicating a min. 18” thickness above the top of the pipe.

C600 - Direct connection of the sanitary service line to the sanitary sewer main stub is not allowed. Please install a new manhole and connect the service line to the sewer main utilizing a cut-in wye.

Sheet L100 - Note: Only ornamental tree varieties are allowed within public easements.

Stormwater Study dated 5/08/23 - Further stormwater review will be completed when the complete study is resubmitted. - Please provide clarification of the specifics of the mentioned waiver. - The 6-inch HDPE from the detention basin must be sized for the 100-year storm event under Comprehensive Control Strategy. The proposed pipe is too small and will need to be reevaluated. This will make the conflict with the water main extension worse and that will also need to be remedied. - Rational method was used for construction of hydrographs. Please use the SCS method and a 24-hour storm with a Type 2 24-hour storm event. - Pond setup table was missing, making the check of outlet structure impossible on the plans. - Emergency overflow? Didn’t see where this was located. - Please provide a single sheet for each detention basin showing the following items: a) Top of dam elevation. b) Emergency spillway elevation. c) All weir and orifice elevations that are part of the outlet structure. d) 100-year nominal (i.e., design) storage volume. e) Bottom of basin elevation. f) Bottom of basin slope callouts, which may be less than 2% to achieve water quality objectives (i.e., we have seen as little as 0.5% in some instances to achieve water quality objectives). g) 100-year nominal (i.e., design) water surface elevation (WSE). h) 100 year clogged/zero available storage WSE. i) Graphical limits of the 100-year clogged/zero available storage WSE (i.e., shown on the plan view with callouts), along with dimensional callouts from property lines and buildings to ensure a minimum 20-foot setback. j) Typical section view of the outlet works and dam, along with elevation callouts for the 100-year nominal and 100 year clogged/zero available storage to ensure there is a minimum 0.5 feet freeboard between the nominal condition and the crest of the emergency spillway, and a minimum 1.0 feet from the clogged condition/zero available storage and the top of dam. k) Location and callouts showing the emergency spillway, and a clear path that is not directed towards buildings or other other vulnerable features. l) 20-foot setback from property line (or buildings) was not met. m) Need 15-foot minimum setback from any public water main.
