Background
The Minnesota Pollution Control Agency (MPCA) developed this document to assist you with the requirements of the MPCA’s Authorization to Discharge Stormwater Associated with small MS4s under the National Pollutant Discharge Elimination System/State Disposal System (NPDES/SDS) Permit (MS4 Permit). The MS4 Permit requires your regulatory mechanism to be as stringent as the MPCA’s Authorization to Discharge Stormwater Associated with Construction Activity under the NPDES/SDS Program (Construction Stormwater Permit) for erosion, sediment, and waste controls. Your written procedure must include a checklist or other written means to document each site inspection you conduct (MS4 Permit Part III.D.4.d.(4) and Part III.D.4.f.(2)). You must retain these documents for three years beyond the term of the MS4 Permit (MS4 Permit Part IV.C.). This document was developed to simplify the Construction Stormwater Permit requirements for erosion, sediment, and waste controls into a checklist format for inspectors to use. The original Construction Stormwater Permit language is included on the "MPCA Permit Requirements" worksheet for your reference.
Using the Checklist
The "Checklist" worksheet is provided as guidance only. You may add more fields for your internal use. You may also use any other form or method to document construction site inspections.

Additional notes and photos
1
The Permittee(s) must plan for and implement appropriate BMPs such as construction phasing, vegetative buffer strips, horizontal slope grading, inspection and maintenance of Part IV.E. and other construction practices that minimize erosion as necessary to comply with this permit and protect waters of the state. The location of areas not to be disturbed must be delineated (e.g., with flags, stakes, signs, silt fence etc.) on the project site before work begins. The Permittee(s) must minimize the need for disturbance of portions of the project that have steep slopes. For those sloped areas which must be disturbed, the Permittee(s) must use techniques such as phasing and stabilization practices designed for steep slopes (e.g., slope draining and terracing). [Part IV. B. 1]
2
The Permittee(s) must stabilize all exposed soil areas (including stockpiles). Stabilization must be initiated immediately to limit soil erosion whenever any construction activity has permanently or temporarily ceased on any portion of the site and will not resume for a period exceeding 14 calendar days. Stabilization must be completed no later than 14 calendar days after the construction activity in that portion of the site has temporarily or permanently ceased. For Public Waters that the Minnesota Department of Natural Resources has promulgated “work in water restrictions” during specified fish spawning time frames, all exposed soil areas that are within 200 feet of the water’s edge, and drain to these waters must complete the stabilization activities within 24 hours during the restriction period. Temporary stockpiles without significant silt, clay or organic components (e.g., clean aggregate stockpiles, demolition concrete stockpiles, sand stockpiles) and the constructed base components of roads, parking lots and similar surfaces are exempt from this requirement but must be in compliance with Part IV.C.5 [Part IV. B. 2] Stabilization of all exposed soil areas must be initiated immediately to limit soil erosion but in no case completed later than seven (7) days after the construction activity in that portion of the site has temporarily or permanently ceased. [Appendix A C.1.a]
3
If using stormwater conveyance channels ,the Permittee(s) must design the channels to route water around unstabilized areas on the site and to reduce erosion, unless infeasible. The Permittee(s) must use erosion controls and velocity dissipation devices such as check dams, sediment traps, riprap, or grouted riprap at outlets within and along the length of any constructed stormwater conveyance channel, and at any outlet, to provide a nonerosive flow velocity, to minimize erosion of channels and their embankments, outlets, adjacent stream banks, slopes, and downstream waters during discharge conditions. [Part IV. B. 3]
4
The Permittee(s) must stabilize the normal wetted perimeter of any temporary or permanent drainage ditch or swale that drains water from any portion of the construction site, or diverts water around the site, within 200 lineal feet from the property edge, or from the point of discharge into any surface water. Stabilization of the last 200 lineal feet must be completed within 24 hours after connecting to a surface water or property edge. The Permittee(s) shall complete stabilization of the remaining portions of any temporary or permanent ditches or swales within 14 calendar days after connecting to a surface water or property edge and construction in that portion of the ditch has temporarily or permanently ceased. Temporary or permanent ditches or swales that are being used as a sediment containment system during construction (with properly designed rockditch checks, bio rolls, silt dikes, etc.) do not need to be stabilized during the temporary period of its use as a sediment containment system. These areas must be stabilized within 24 hours after no longer being used as a sediment containment system. Applying mulch, hydromulch, tackifier, polyacrylamide or similar erosion prevention practices is not acceptable stabilization in any part of a temporary or permanent drainage ditch or swale. [Part IV. B. 4]
5
Pipe outlets must be provided with temporary or permanent energy dissipation within 24 hours after connection to a surface water. [Part IV. B. 5]
6
Unless infeasible due to lack of pervious or vegetated areas, the Permittee(s) must direct discharges from BMPs to vegetated areas of the site (including any natural buffers) in order to increase sediment removal and maximize stormwater infiltration. The Permittee(s) must use velocity dissipation devices if necessary to prevent erosion when directing stormwater to vegetated areas. [(MNR100001) Part IV. B. 6]
7
The Permittee(s) must employ Sediment control practices as necessary to minimize sediment from entering surface waters, including curb and gutter systems and storm sewer inlets. a. Temporary or permanent drainage ditches and sediment basins that are designed as part of a sediment containment system (e.g., ditches with rockcheck dams) require sediment control practices only as appropriate for site conditions. b. If the down gradient sediment controls are overloaded (based on frequent failure or excessive maintenance requirement), the Permittee(s) must install additional upgradient sediment control practices or redundant BMPs to eliminate the overloading, and the SWPPP must be amended to identify these additional practices as required in Part III.B 1.3. [Part IV.C.1.]
8
Sediment control practices must be established on all down gradient perimeters and be located upgradient of any buffer zones. The perimeter sediment control practice must be in place before any upgradient landdisturbing activities begin. These practices shall remain in place until Final Stabilization has been established in accordance with Part IV.G.  A floating silt curtain placed in the water is not a sediment control BMP to satisfy perimeter control requirements in this part except when working on a shoreline and below the waterline.  In those cases, a floating silt curtain can be used as a perimeter control practice if the floating silt curtain is installed as close to shore as possible. Immediately after the short term construction activity (e.g. installation of rip rap along the shoreline) in that area is complete, an upland perimeter control practice must be installed if exposed soils still drain to the surface water. [Part IV. C. 2]
9
The Permittee(s) shall reinstall all sediment control practices that have been adjusted or removed to accommodate shortterm activities such as clearing or grubbing, or passage of vehicles, immediately after the shortterm activity has been completed. The Permittee(s) shall complete any shortterm activity that requires removal of sediment control practices as quickly as possible. The Permittee(s) must reinstall sediment control practices before the next precipitation event even if the shortterm activity is not complete. [Part IV.C.3.]
10
All storm drain inlets must be protected by appropriate BMPs during construction until all sources with potential for discharging to the inlet have been stabilized. Inlet protection may be removed for a particular inlet if a specific safety concern (street flooding/freezing) has been identified by the Permittee(s) or the jurisdictional authority (e.g., city/county/township/MnDOT engineer).The Permittee(s) must document the need for removal in the SWPPP.  [Part IV. C. 4]
11
Temporary soil stockpiles must have silt fence or other effective sediment controls, and cannot be placed in any natural buffers or surface waters, including stormwater conveyances such as curb and gutter systems, or conduits and ditches unless there is a bypass in place for the stormwater. [Part IV. C. 5]
12
Where vehicle traffic leaves any part of the site (or onto paved roads within the site): a. The Permittee(s) must install a vehicle tracking BMP to minimize the track out of sediment from the construction site. Examples of vehicle tracking BMPs include (but are not limited to) rock pads, mud mats, slash mulch, concrete or steel wash racks, or equivalent systems. b. The Permittee(s) must use street sweeping if such vehicle tracking BMPs are not adequate to prevent sediment from being tracked onto the street (see Part IV.E.5.d.). [Part IV. C. 6]
13
The Permittee(s) must minimize soil compaction and, unless infeasible, preserve topsoil.   Minimizing soil compaction is not required where the function of a specific area of the site dictates that it be compacted. [Part IV. C. 8] 
14
The Permittee(s) must preserve a 50 foot natural buffer or (if a buffer is infeasible on the site) provide redundant sediment controls when a surface water is located within 50 feet of the project’s earth disturbances and stormwater flows to the surface water. Natural buffers are not required adjacent to road ditches, judicial ditches, county ditches, stormwater conveyance channels, storm drain inlets, and sediment basins. The Permittee(s) is/are not required to enhance the quality of the vegetation that already exists in the buffer or provide vegetation if none exist. However, Permittee(s) can improve the natural buffer with vegetation. [Part IV. C. 9] 
15
If the Permittee(s) intend to use polymers, flocculants, or other sedimentation treatment chemicals on the project site, the Permittee(s) must comply with the following minimum requirements: a. The Permittee(s) must use conventional erosion and sediment controls prior to chemical addition to ensure effective treatment. Chemicals may only be applied where treated stormwater is directed to a sediment control system which allows for filtration or settlement of the floc prior to discharge. b. Chemicals must be selected that are appropriately suited to the types of soils likely to be exposed during construction, and to the expected turbidity, pH, and flow rate of stormwater flowing into the chemical treatment system or area. c. Chemicals must be used in accordance with accepted engineering practices, and with dosing specifications and sediment removal design specifications provided by the manufacturer or provider/supplier of the applicable chemicals. [Part IV. C. 10] 
16
The Permittee(s) must inspect all erosion prevention and sediment control BMPs and Pollution Prevention Management Measures to ensure integrity and effectiveness during all routine and postrainfall event nspections. All nonfunctional BMPs must be repaired, replaced, or supplemented with functional BMPs by the end of the next business day after discovery, or as soon as field conditions allow access unless another time frame is specified below. The Permittee(s) must investigate and comply with the following inspection and maintenance requirements: [(MNR100001) Part IV. D. 5] All perimeter control devices must be repaired, replaced, or supplemented when they become nonfunctional or the sediment reaches onehalf (1/2) of the height of the device. These repairs must be made by the end of the next business day after discovery, or thereafter as soon as field conditions allow access. [Part IV. D. 5. a.] 
17
All perimeter control devices must be repaired, replaced, or supplemented when they become nonfunctional or the sediment reaches onehalf (1/2) of the height of the device. These repairs must be made by the end of the next business day after discovery, or thereafter as soon as field conditions allow access. [Part IV. D. 5. a.] 
18
Surface waters, including drainage ditches and conveyance systems, must be inspected for evidence of erosion and sediment deposition during each inspection. The Permittee(s) must remove all deltas and sediment deposited in surface waters, including drainage ways, catch basins, and other drainage systems, and restabilize the areas where sediment removal results in exposed soil. The removal and stabilization must take place within seven (7) days of discovery unless precluded by legal, regulatory, or physical access constraints. The Permittee(s) shall use all reasonable efforts to obtain access. If precluded, removal and stabilization must take place within seven (7) calendar days of obtaining access. The Permittee(s) is/are responsible for contacting all local, regional, state and federal authorities and receiving any applicable permits, prior to conducting any work in surface waters. [Part IV. D. 5. c.] 
19
Construction site vehicle exit locations must be inspected for evidence of offsite sediment tracking onto paved surfaces. Tracked sediment must be removed from all paved surfaces both on and off site within 24 hours of discovery, or if applicable, within a shorter time to comply with Part IV.C.6. e. Streets and other areas adjacent to the project must be inspected for evidence of offsite accumulations of sediment. If sediment is present, it must be removed in a manner and at a frequency sufficient to minimize offsite impacts (e.g., fugitive sediment in streets could be washed into storm sewers by the next rain and/or pose a safety hazard to users of public streets). [Part IV. D. 5. d. & e.]
20
All infiltration areas must be inspected to ensure that no sediment from ongoing construction activity is reaching the infiltration area. All infiltration areas must be inspected to ensure that equipment is not being driven across the infiltration area. [Part IV. D. 6.] 
21
The Permittee(s) must ensure that a trained person (as identified in Part III.A.3.a.) will routinely inspect the entire construction site at least once every seven (7) days during active construction and within 24 hours after a rainfall event greater than 0.5 inches in 24 hours. Following an inspection that occurs within 24 hours after a rainfall event, the next inspection must be conducted within seven (7) days after the rainfall event. 2. All inspections and maintenance conducted during construction must be recorded within 24 hours in writing and these records must be retained with the SWPPP in accordance with Part III.E. Records of each inspection and maintenance activity shall include: a. Date and time of inspections b. Name of person(s) conducting inspections c. Findings of inspections, including the specific location where corrective actions are needed d. Corrective actions taken (including dates, times, and party completing maintenance activities) e. Date and amount of all rainfall events greater than 1/2 inch (0.5 inches) in 24 hours. Rainfall amounts must be obtained by a properly maintained rain gauge installed onsite, a weather station that is within 1 mile of your location or a weather reporting system that provides site specific rainfall data from radar summaries. f. If any discharge is observed to be occurring during the inspection, a record of all points of the property from which there is a discharge must be made, and the discharge should be described (i.e., color, odor, floating, settled, or suspended solids, foam, oil sheen, and other obvious indicators of pollutants) and photographed. g. Any amendments to the SWPPP proposed as a result of the inspection must be documented as required in Part III.B. within seven (7) calendar days. [Part IV. E. 1 & 2.] 
22
Storage, Handling, and Disposal of Construction Products, Materials, and Wastes: The Permittee(s) shall comply with the following to minimize the exposure to stormwater of any of the products, materials, or wastes. Products or wastes which are either not a source of contamination to stormwater or are designed to be exposed to stormwater are not held to this requirement: a. Building products that have the potential to leach pollutants must be under cover (e.g., plastic sheeting or temporary roofs) to prevent the discharge of pollutants or protected by a similarly effective means designed to minimize contact with stormwater. b. Pesticides, herbicides, insecticides, fertilizers, treatment chemicals, and landscape materials must be under cover (e.g., plastic sheeting or temporary roofs) to prevent the discharge of pollutants or protected by similarly effective means designed to minimize contact with stormwater. [Part IV. F. 1. a. & b.] 
23
Hazardous materials, toxic waste, (including oil, diesel fuel, gasoline, hydraulic fluids, paint solvents, petroleumbased products, wood preservatives, additives, curing compounds, and acids) must be properly stored in sealed containers to prevent spills, leaks or other discharge. Restricted access storage areas must be provided to prevent vandalism. Storage and disposal of hazardous waste or hazardous materials must be in compliance with Minn. R. ch. 7045 including secondary containment as applicable. d. Solid waste must be stored, collected and disposed of properly in compliance with Minn. R. ch. 7035. [Part IV. F. 1. a. & b.] 
24
Portable toilets must be positioned so that they are secure and will not be tipped or knocked over. Sanitary waste must be disposed of properly in accordance with Minn. R. ch. 7041. [Part IV. F. 1. e.]
25
Fueling and Maintenance of Equipment or Vehicles; Spill Prevention and Response: The Permittee(s) shall take reasonable steps to prevent the discharge of spilled or leaked chemicals, including fuel, from any area where chemicals or fuel will be loaded or unloaded including the use of drip pans or absorbents unless infeasible. The Permittee(s) must conduct fueling in a contained area unless infeasible. The Permittee(s) must ensure adequate supplies are available at all times to clean up discharged materials and that an appropriate disposal method is available for recovered spilled materials. The Permittee(s) must report and clean up spills immediately as required by Minn. Stat. § 115.061, using dry clean up measures where possible. [Part IV. F. 2.]
26
Vehicle and equipment washing: If the Permittee(s) wash the exterior of vehicles or equipment on the project site, washing must be limited to a defined area of the site. Runoff from the washing area must be contained in a sediment basin or other similarly effective controls and waste from the washing activity must be properly disposed of. The Permittee(s) must properly use and store soaps, detergents, or solvents. No engine degreasing is allowed on site. [Part IV. F. 3.]
27
Concrete and other washouts waste: The Permittee(s) must provide effective containment for all liquid and solid wastes generated by washout operations (concrete, stucco, paint, form release oils, curing compounds and other construction materials) related to the construction activity. The liquid and solid washout wastes must not contact the ground, and the containment must be designed so that it does not result in runoff from the washout operations or areas. Liquid and solid wastes must be disposed of properly and in compliance with MPCA rules. A sign must be installed adjacent to each washout facility that requires site personnel to utilize the proper facilities for disposal of concrete and other washout wastes. [Part IV. F. 4.]
28
The owner must develop a Stormwater Pollution Prevention Plan (SWPPP). The SWPPP shall be completed prior to submitting any permit application and prior to conducting any construction activity by any required Permittee(s). For stormwater discharges from construction activity where the owner or operator changes, the new owner or operator can implement the original SWPPP created for the project, modify the original SWPPP, or develop and implement their own SWPPP. Permittee(s) shall ensure either directly or through coordination with other Permittee(s) that their SWPPP meets all terms and conditions of this permit and that their activities do not render another party’s erosion prevention and sediment control BMPs ineffective. [Part III. A]
29
Where a project’s ultimate development replaces vegetation and/or other pervious surfaces with one (1) or more acres of cumulative impervious surface, the Permittee(s) must design the project so that the water quality volume of one (1) inch of runoff from the new impervious surfaces created by the project is retained on site (i.e. infiltration or other volume reduction practices) and not discharged to a surface water. For purposes of this part, surface waters does not include manmade drainage systems that convey stormwater to a compliant permanent stormwater management system. [Part III. D]

Where ten (10) or more acres of disturbed soil drain to a common location, the Permittee(s) must provide a temporary sediment basin to provide treatment to the runoff before it leaves the construction site or enters surface waters. A temporary sediment basin may be converted to a permanent basin after construction is complete. The temporary basin is no longer required when permanent cover has reduced the acreage of disturbed soil to less than ten (10) acres draining to a common location. The Permittee(s) is/are encouraged, but not required, to install temporary sediment basins where appropriate in areas with steep slopes or highly erodible soils even if less than ten (10) acres drains to one area.[Part III. C] Temporary sediment basin requirements described in Part III.C. must be used for common drainage locations that serve an area with five (5) or more acres disturbed at one time. [Appendix A C.1.a]
31
The outlet structure must be designed to withdraw water from the surface in order to minimize the discharge of pollutants, except that the use of a surface withdrawal mechanism for discharge of the basin may be temporarily suspended during frozen conditions. Energy dissipation must be provided for the basin outlet (see Part IV.B.5.). [Part III. C.3.]
32
The basin must be designed with the ability to allow complete basin drawdown for maintenance activities, and must include a stabilized emergency overflow to prevent failure of pond integrity. [Part III. C.3.]
33
Temporary and permanent sedimentation basins must be drained and the sediment removed when the depth of sediment collected in the basin reaches onehalf (1/2) the storage volume. Drainage and removal must be completed within 72 hours of discovery, or as soon as field conditions allow access (see Part IV.D.). [Part IV. D. 5.b.] 
34
The Permittee(s) must discharge turbid or sedimentladen waters related to dewatering or basin draining (e.g., pumped discharges, trench/ditch cuts for drainage) to a temporary or permanent sedimentation basin on the project site unless infeasible. The Permittee(s) may discharge from the temporary or permanent sedimentation basins to surface waters if the basin water has been visually checked to ensure adequate treatment has been obtained in the basin and that nuisance conditions (see Minn. R. 7050.0210, subp. 2) will not result from the discharge. If the water cannot be discharged to a sedimentation basin prior to entering the surface water, it must be treated with the appropriate BMPs, such that the discharge does not adversely affect the receiving water or downstream properties. If the Permittee(s) must discharge water that contains oil or grease, the Permittee(s) must use an oilwater separator or suitable filtration device (e.g. cartridge filters, absorbents pads) prior to discharging the water. The Permittee(s) must ensure that discharge points are adequately protected from erosion and scour. The discharge must be dispersed over natural rock riprap, sand bags, plastic sheeting, or other accepted energy dissipation measures. [Part IV. D. 1.]
35
All water from dewatering or basindraining activities must be discharged in a manner that does not cause nuisance conditions, erosion in receiving channels or on downslope properties, or inundation in wetlands causing significant adverse impact to the wetland. [Part IV. D. 2.]
36
If the Permittee(s) is/are using filters with backwash water, the Permittee(s) must haul the backwash water away for disposal, return the backwash water to the beginning of the treatment process, or incorporate the backwash water into the site in a manner that does not cause erosion. The Permittee(s) may discharge backwash water to the sanitary sewer if permission is granted by the sanitary sewer authority.  The Permittee(s) must replace and clean the filter media used in dewatering devices when required to retain adequate function. [Part IV. D. 3.]
37
For Public Waters that the Minnesota Department of Natural Resources has promulgated “work in water restrictions” during specified fish spawning time frames, all exposed soil areas that are within 200 feet of the water’s edge, and drain to these waters must complete the stabilization activities within 24 hours during the restriction period. Temporary stockpiles without significant silt, clay or organic components (e.g., clean aggregate stockpiles, demolition concrete stockpiles, sand stockpiles) and the constructed base components of roads, parking lots and similar surfaces are exempt from this requirement but must be in compliance with Part IV.C.5 [(MNR100001) Part IV. B. 2] Stabilization of all exposed soil areas must be initiated immediately to limit soil erosion but in no case completed later than seven (7) days after the construction activity in that portion of the site has temporarily or permanently ceased. [(MNR100001) Appendix A C.1.a]
38
Buffer zone: The Permittee(s) shall include an undisturbed buffer zone of not less than 100 linear feet from the special water (not including tributaries) and this buffer zone shall be maintained at all times, both during construction and as a permanent feature post construction, except where a water crossing or other encroachment is necessary to complete the project. The Permittee(s) must fully document the circumstance and reasons that the buffer encroachment is necessary in the SWPPP and include restoration activities. Replacement of existing impervious surface within the buffer is allowed under this permit. All potential water quality, scenic and other environmental impacts of these exceptions must be minimized by the use of additional or redundant BMPs and documented in the SWPPP for the project. [Appendix A C.3.]
39
Temporary sediment basin requirements described in Part III.C. must be used for common drainage locations that serve an area with five (5) or more acres disturbed at one time. [Appendix A C.1.a]
40
All soil disturbing activities at the site have been completed and all soils are stabilized by a uniform perennial vegetative cover with a density of 70 percent of its expected final growth density over the entire pervious surface area, or other equivalent means necessary to prevent soil failure under erosive conditions. [Part IV. G. 5.1.] 
41
42
Temporary or permanent sedimentation basins that are to be used as permanent water quality management basins have been cleaned of any accumulated sediment. All sediment has been removed from conveyance systems and ditches are stabilized with permanent cover. [Part IV. G. 5.2.] 
43
All temporary synthetic and structural erosion prevention and sediment control BMPs (such as silt fence) have been removed on the portions of the site for which the Permittee(s) is/are responsible. BMPs designed to decompose on site (such as some compost logs) may be left in place. [Part IV. G. 5.3.] 
44
For residential construction only, individual lots are considered finally stabilized if the structure(s) are finished and temporary erosion protection and downgradient perimeter control has been completed and the residence has been sold to the homeowner. Additionally, the Permittee has distributed the MPCA’s “Homeowner Fact Sheet” to the homeowner to inform the homeowner of the need for, and benefits of, permanent cover. [Part IV. G. 4.]
45
For construction projects on agricultural land (e.g., pipelines across crop, field pasture or range land) the disturbed land has been returned to its preconstruction agricultural use. [Part IV. G. 4.]

MEMORANDUM
TO: Joe Hogeboom, Director of Community and Economic Development FROM: John Hagen, P.E., PTOE, Transportation Operations Engineer DATE: March 24, 2021 SUBJECT: Shake Shack Traffic and Parking Study – City Review Comments The purpose of this memorandum is to summarize my review of Westwood’s memo, dated March 23, 2021 that summarizes the trip generation, drive-through analysis, and parking analysis that was completed for the proposed Shake Shack located in an existing outlot of the Shoppes at Arbor Lakes development.
Review Comments I have reviewed the Westwood memo dated March 23, 2021 that summarizes their trip generation, drive-through queuing, and parking analysis, and offer the following comments. A copy of Westwood’s Shake Shack Traffic and Parking Study memo is attached.
1. Trip Generation:
a. The proposed 3,200 SF restaurant is anticipated to generate approximately 1,500 trips on an average weekday with 163 trips occurring during the a.m. peak hour (85 inbound and 78 outbound trips), and 164 trips occurring during the a.m. peak hour (83 inbound and 81 outbound trips). It is anticipated that the restaurant’s peak period will occur during the midday on Saturdays. During this Saturday midday peak hour, the proposed restaurant will likely generate approximately 432 trips (216 inbound and 216 outbound).
b. The trip generation assumptions are reasonable and acceptable given the fact that they were based on the trip generation estimates for a fast-food restaurant with a drive-through provided in the 10th Edition of the Institute of Transportation Engineers Trip Generation Manual.
2. Trip Distribution and Assignment:
a. The traffic study assumed that 85 percent of the traffic to/from the restaurant would enter the site from Elm Creek Boulevard, while 15 percent would enter the site from other nearby roadways (i.e. – Main Street to the west and south, and Hemlock Lane to the east).
b. The trip distribution assumptions are reasonable and consistent with past traffic studies that have been conducted within the vicinity of the proposed development.
Shake Shack Traffic and Parking Study – City Review Comments March 24, 2021 Page 2
c. A review of the total trip assignment shown in Figure 5 of the Shake Shack Traffic and Parking Study memo revealed that the proposed restaurant will add less than one (1) vehicle per minute to any of the turning movements in/out of the Shoppes at Arbor Lakes development at the signalized Elm Creek Boulevard intersection with the Mall/Great River Energy Entrance.
d. Recent traffic analysis of the signalized intersection of Elm Creek Boulevard with the Mall/Great River Energy Entrance revealed that it currently operates at an acceptable level of service (LOS) C during the weekday p.m. peak.
e. Since the key intersection of Elm Creek Boulevard with the Mall/Great River Energy Entrance currently operates at an acceptable LOS C during the weekday p.m., and the proposed Shake Shack will likely add less than one additional vehicle to any turning movements in/out of the Shoppes at Arbor Lakes during the peak hour, a detailed operational analysis is not required on the public roadway system.
3. Drive-Through Queuing Analysis:
a. The drive-through queuing analysis used that same methodology that was used for a Chick-fil-A restaurant in Washington State that has a similar dual-lane drive- through configuration as the proposed Maple Grove Shake Shack.
b. The queueing analysis methodology is acceptable and the results seem reasonable.
c. The anticipated 95th-percentile queue length of 12 vehicles at the drive-through is consistent with the City’s expectation (12 to 14 vehicles) for similar restaurants with drive throughs.
d. The proposed on-site drive-through queue storage of 16 vehicles is sufficient to accommodate the typical demand (12 vehicles) of the proposed Shake Shack .
e. The City appreciates that the applicant has developed a traffic management plan to deal with the potential times when the drive-through demand exceeds the proposed on-site drive-through queue storage. The proposed traffic management plan should help to minimize the likelihood of the drive- through spilling back onto the shopping center’s northern internal circulatory road (see attached Shake Shack memo dated 3/16/2021).
4. Parking Analysis:
a. The existing parking field where the Shake Shack restaurant is proposed to be constructed contains 344 parking spaces. The construction of the restaurant will remove 79 parking spaces leaving 265 parking spaces for the proposed restaurant, the existing Red Lobster, and the existing Building “A” of the Shoppes at Arbor Lakes.
b. An existing easement agreement with Red Lobster requires that at least 264 parking spaces are required to be maintained in this parking field. The remaining 265 parking spaces provides one more than what is required in this agreement.
Shake Shack Traffic and Parking Study – City Review Comments March 24, 2021 Page 3
c. The Traffic and Parking Study estimates that the proposed Shake Shack and existing Building “A” have a peak parking demand of 198 parking spaces.
i. The Traffic and Parking Study states that the proposed restaurant will require 28 of these remaining 265 parking spaces.
ii. Using parking demand numbers form ITE’s Parking Generation Manual, the 46,873 SF Building “A” has a peak parking demand of 170 parking spaces.
d. The parking analysis is acceptable and the City agrees with the findings that the existing parking field (even after a loss of parking due to the proposed Shake Shack) is adequate for the estimated demand.
If you have any questions, please contact me at your earliest convenience at (763) 494-6364.

Date: March 23, 2021 Re: Shoppes at Arbor Lakes Outlot – Response to Traffic Comments File #0024684.00 To: John Hagen, P.E., PTOE, City of Maple Grove Transportation Operations Engineer From: Paul Villaluz, P.E., PTOE, RSP1
This memorandum has been prepared as a response to comments for the Shoppes at Arbor Lakes Outlot project that were listed in an e-mail from the City of Maple Grove dated March 1, 2021. Further comments from the City of Maple Grove were received in an e-mail dated March 4, 2021 and an e-mail dated March 23, 2021. All of the City of Maple Grove e-mails are included in Appendix A. This memorandum will contain the following:
• Trip Generation Analysis • Drive-Through Queuing Analysis • Parking Analysis
The Shoppes at Arbor Lakes Outlot project will be developed as a Shake Shack restaurant with double drive-through lanes. A Preliminary Site Plan is included as Appendix E.
Trip Generation
The 10th Edition of the Institute of Transportation Engineers’ (ITE) Trip Generation Manual was used to estimate the number of vehicle trips that could be generated by the project. This manual is a standard reference used by municipalities and public agencies throughout the United States. The trip generation characteristics included in the manual are summarized by general land use type and are based on actual trip generation studies performed at numerous locations in areas of various populations.
There is no trip generation available for a Shake Shack restaurant with double drive-through lanes. Trip generation for the proposed Shoppes at Arbor Lakes Outlot project is based on average rate equations for the peak hour of generation for a Fast-Food Restaurant with Drive- Through (ITE Land Use Code 934). The resulting trip generation is summarized in Table 1. Calculations are provided in Appendix B.

ITE defines pass-by trips as trips that are “made as intermediate stops on the way from an origin to a primary trip destination without a route diversion”. Pass-by trips are attracted from traffic passing the site on an adjacent street or roadway that offers direct access to the generator. ITE has identified the following pass-by trip rates for the land uses below:
• Fast-Food Restaurant with Drive-Through Window (ITE Land Use 934)
o 49% during the AM peak hour and 50% during the PM peak hour
The pass-by trip rates summarized above were applied to the project trips summarized in Table 1, with the resultant pass-by trip generation for the Shoppes at Arbor Lakes Outlot project summarized in Table 2.

Trip Distribution
The directional distribution of project traffic quantifies the percentage of project-generated traffic that arrives and departs the project site in each direction by type of use. This project includes uses that generate primary and pass-by project trips. The primary trip distribution quantifies the percentage of site-generated traffic that generally arrives and departs the project site along the same route. Primary trips are new trips to the street network and project driveways. Figure 1 illustrates the anticipated primary project trip distribution for the Shoppes at Arbor Lakes Outlot project. The primary trip distribution is based on anticipated access restrictions and internal circulation through each project driveway, anticipated trip origins and destinations with the surrounding areas, and engineering judgment.
The pass-by trip distribution quantifies the percentage of site-generated traffic that makes intermediate stops on the way from an origin to a primary trip destination without a route diversion. Figure 2 illustrates the anticipated pass-by project distribution during the AM and PM peak hours. Pass-by trips are attracted from traffic passing the site on an adjacent street or roadway such as Elm Creek Boulevard that offers direct access to the generator. Therefore, they generally divert from their original direction of travel into the project site and then exit the site and continue in their original direction of travel. Pass-by trips are not new trips to the street network but they are new project driveway trips. The pass-by trip distribution was based on the anticipated trip distribution at the intersection of Elm Creek Boulevard and the Mall Entrance.
Trip Assignment
Project traffic assignment was calculated by applying the pass-by trip distribution percentages found in Figure 2 to the pass-by project trip generation found in Table 2 and the primary trip distribution percentages found in Figure 1 to the primary project trip generation found in Table 3. The resulting traffic assignments at the intersections are illustrated in Figure 3 for the primary trip assignment and Figure 4 for the pass-by trip assignment. The total traffic assignment is provided in Figure 5.
Queuing Analysis
The methodologies outlined in the attached Traffic Impact Analysis for a Chick-fil-A restaurant with double drive-through lanes in Fircrest, Washington (see Appendix C) were used for the purpose of estimating the anticipated drive-through storage needs.
The average queue storage length was calculated using the following equation for a M/M/1 queue model:
Average Queue Length (veh) = 2
1− ;
ρ = λ / μ
0024684.00
The 95th Percentile Queue Length (veh) is calculated as a function of the Average Queue Length with the following equation from Paper No. 01-2019 of Transportation Research Record 1776.
95% = 1.3 + 2.1√ +
+ 4.6
where L = Average Queue Length (veh)
The future drive-through queue calculations for this restaurant are listed in Table 4. It is assumed that 80% of the vehicles that arrive during the worst-case peak hour (AM peak hour) will use the drive-through lanes.
Service time is defined as the amount of time that a vehicle spends at the window completing a transaction and receiving their order and the “move up” time. This includes time to pay, time to receive the food order, and the time for the next vehicle to move up to the pick-up window. A 45-second service time is assumed for the AM peak hour based on the Chick-fil-A TIA.
Table 4 – Shoppes at Arbor Lakes Outlot Future Drive-Through Queue Calculations
80% of #
68 60 1.1 45 1.3 0.85 5 12
The project site plan included in Appendix E illustrates a queue storage of 220 feet on the inside lane and 184 feet on the outside lane. The proposed queue storage is anticipated to accommodate a total of 16 vehicles – 9 vehicles on the inside lane and 7 vehicles on the outside lane. Therefore, the proposed on-site queue storage is sufficient for anticipated demand.
Even though the proposed on-site queue storage is anticipated to be sufficient for the expected demand, Shake Shack staff will enact the following procedures on an as-needed basis during periods of increased demand (i.e., opening weeks, extremely busy peak hours, etc.) to lessen the possibility of spillback onto the northern internal road.
• Traffic cones will be used to reduce the possibility of spillback into the northern internal road and to extend the drive through lanes through the existing parking field.
• Shake Shack staff members will take orders remotely in the drive through lanes and direct traffic as needed.
• Customers with orders that will take longer to fulfill will be asked to park in designated spaces to keep the pick-up window clear. Shake Shack staff will deliver the completed orders to patrons parked in these spaces.
Please see Figure 6 for more information.

Parking Analysis
Presently there are 344 stalls in the parking field located to the west of the project. The footprint of the proposed restaurant is anticipated to remove 79 stalls from the parking field. CBRE proposes to provide 265 on-site parking stalls within the parking field directly to the west of the proposed restaurant.
This number of stalls is one more than the 264 stalls that are required to be maintained in the attached easement agreement with the Red Lobster that is directly located to the west of the project (see Appendix D).
The 265 stalls in this parking field will most likely serve the Shake Shack project and portion of the businesses in Building A of the Shoppes at Arbor Lakes. Building A is presently partially occupied – Areas A1, A6, A7, A13, and A24 are currently vacant (see Appendix D).
Shake Shack
According to the 5th edition of ITE’s Parking Generation Manual, the peak parking demand rate for Land Use Code 934 is 8.66 stalls per 1,000 sf GFA. The resulting estimated peak parking demand is 28 stalls (i.e., 8.66 stalls x 3.2 ksf GFA) (see Appendix D).
According to a parking study prepared by Westwood on January 20, 2020, the 5,165 sf Shake Shack on 6603 France Ave S in Edina, Minnesota had an observed peak parking demand of 35 stalls. The resulting peak parking demand rate is 6.77 stalls per 1,000 sf GFA (i.e., 35 stalls / 5.165 ksf GFA). Application of this peak parking demand rate to the proposed 3.2 ksf project results in a peak parking demand estimate of 22 stalls (see Appendix D).
Building A
Data from the 5th edition of ITE’s Parking Generation Manual estimates the peak parking demand of the existing Building A (46,873 sf) to be 170 stalls. This is based on ITE Land Use Code 820 (Shopping Center).
Total
A conservative estimate of parking demand for this field of 198 stalls is calculated by adding the 28 stalls for the Shake Shack to the 170 stalls for a fully-occupied Building A.
The 265 stalls provided in the parking field are adequate for this conservatively estimated demand of 198 stalls.
