HomeMy WebLinkAbout#20 - School Bus Facility STAFF REPORT DATE: 1/7/2020 REGULAR TO: City Council FROM: Ben Prchal, City Planner AGENDA ITEM: Stillwater School District Conditional Use Permit Amendment REVIEWED BY: Ken Roberts, Planning Director Sarah Sonsalla, City Attorney Planning Commission City Council
BACKGROUND: The Stillwater School District is requesting an amendment to its conditional use permit (“CUP”) to operate a school district transportation center (bus terminal) on its property located at 11530 Hudson Boulevard North. The CUP was issued by the City to the School District on July 17, 2019 through Resolution #2018-077. One of the conditions in the CUP is that “[t]he property shall be connected to City sewer and water prior to the operation of the bus terminal.” The School District’s property is part of the Four Corners 1st Addition plat that was approved by the
City Council in 2018. A condition of the plat approval was that the developer (who is not the School District) was to construct sanitary sewer and water facilities which would have brought sanitary sewer and water service to the School District’s property. The developer was to complete these improvements no later than October 31, 2019. As of this date, construction has not yet commenced. The School District has made all of the improvements on the property that were required by the CUP conditions with the exception of connecting the property to sanitary sewer and water services. The City Council previously reviewed the request at the December 17, 2019 meeting and opted
to table the request until January 7th, 2020. ISSUE BEFORE THE CITY COUNCIL: The School District is requesting an amendment to the CUP to amend Condition #9 of the CUP from “the property shall be connected to City Sewer and Water prior to operation of the bus terminal” to “[t]he School District may operate its bus terminal at the property using the well and septic system (septic tank and temporary toilets) either
until the School District connects to City sewer and water or until December 31, 2020, whichever comes first. The School District agrees to connect to City sewer and water within 30 days after it becomes available.” The Council is being asked approve or deny the requested amendment to the CUP.

CONDITIONAL USE PERMIT Preivous Interim Use Permit. The School District’s property previously operated with an interim use permit which was granted by City Council Resolution No. 2014-095, which was for a bus/truck terminal. The use was similar but focused more on the maintenance of larger trucks. This interim use permit would have expired on
December 2, 2019. In this instance, the interim use permit was terminated upon the rezoning of the School District property
which was affiliated with the Four Corners First Addition development. Another condition of the IUP was that a portion of the property would need to be used for agricultural purposes or left available for agriculture. Development discussions lead to the realization that this might not be practical; and so, the School District also no longer wanted to operate under the interim use permit for this reason. Existing Conditions. The School District received an approved CUP on July 17th, 2018 and since has moved into the building/site and have been operating there since October/November of this year (see School District’s narrative). The School District has completed all of the on-site improvements that were required by the CUP with the exception of the connection of the property to sanitary sewer and water, along with other various improvements in the amount of more than two million dollars. For sewage disposal, the School District has installed a temporary septic tank that is supplemented by temporary toilets (this has been approved by the County). For water, the School District has been
using the existing well on the property (the well was approved by the Minnesota Department of Health for use). Currently, the School District is in violation of the CUP because Condition # 9 states that City sewer and water shall be connected to the building/site prior to the commencement of formal operations. Current Building. The current building was constructed in the 1990s and was used for office space by E&H Earthmovers and also provided bus storage for the School District. It was then used by Kenworth Diesel Trucks for
sales, repairs and service of diesel trucks. As mentioned earlier, the building and site has received a two-million-dollar investment by the School District over the course of the past year. Previous Bus Terminal Operation. The previous location for the School District’s bus terminal was in Oak Park Heights in the Old Junker Landfill. Bus Washing. The School District indicated on its application that the property use will include washing buses. The School District has indicated that the buses will be washed at the facility’s wash bay and that waste water from the wash bay will run in to an oil separator with all of the shop drains, which will go in to a holding tank, which is then disposed of by a sewer transport service. The oil separator is then emptied and maintained by a licensed transporter. The School District indicates that once the property is connected to the City’s sanitary sewer system that the wastewater will go directly to the treatment plant after passing through the oil separator, and the oil separator will be emptied and maintained by a licensed transporter. The disposal of this water is addressed in the engineering comments.
City Engineer Review. Engineering concerns were finalized during the preliminary and final plat of Four Corners 1st Addition and the initial approval of the School District’s CUP.
Fire Chief and Building Official Review. The Fire Chief and Building Official are concerned that that the building is sprinklered yet not connected to City water. Therefore, if there was a fire in the building, the sprinkler system
would not function.

FINDINGS: Staff is recommending denial of the amendment to the CUP for the transportation center at 11530 Hudson Blvd N based on the following findings:
1. The developer of Four Corners 1st Addition has had more than one year to construct the sanitary sewer and water facilities that are needed for the School District’s bus facility and has not done so. In fact, the developer has not started construction of the project. To date, there has been no written assurances given to the City by the developer of the Four Corners project that the sanitary sewer and water facilities that are needed for the operation of the bus terminal will be constructed at any time in the near future. 2. Properties that are within a MUSA district are required to connect to City water and sanitary sewer when
they are developed. The School District’s property is located within a MUSA district. Since it is not connected to City water and sanitary sewer services, it is in conflict with the requirements of the MUSA district, as outlined by the Comprehensive Plan and the use should not be allowed to continue due to this
conflict. 3. The building on the property is sprinklered yet not connected to City water. There is a safety hazard to the
occupants of the building if the building is allowed to operate without the sprinkler system functioning, even if it is for a limited amount of time. Recommended Conditions of Approval. None – All conditions from Resolution 2018-77 shall remain in place.
FISCAL IMPACT: When the School District connects to City water and sanitary sewer, it will be required to pay the City sewer and water availability charges and will be responsible at its sole cost for bringing sewer and water into the site. The City will collect Sewer Accessibility Charges (SAC) and Water Accessibility Charges (WAC) and building permit fees.
OPTIONS: The Council may:
Recommend approval of the amendment to the CUP as proposed by the School District.
Recommend approval of the amendment to the CUP with changes.
Recommend denial of the amendment to the CUP.
If the request is denied by the City Council, it would mean that the School District would be in violation of Condition #9 of its CUP. The City Council could then take separate action to revoke the CUP by holding a public hearing on the revocation. If the City Council revokes the CUP, the School District would no longer be able to operate its bus terminal on the property. CITY STAFF/PLANNING COMMISSION RECOMMENDATION: Planning Commission Recommendation: On December 9th, 2019 the Planning Commission held a public hearing and after discussion voted 6-0 to recommend approval of the amendment request with a change to their request. The Commission suggests striking “…within 30
days after it becomes available.” And replace it with “…as soon as practical.” City Staff believes this statement could potentially open up a conversation of “what becomes practical?” but is not concerned with there being difficulty enforcing the condition, if approved. The Commission further thought if the request had ground for approval. Furthermore, there was expressed sympathy for the District because they were at the mercy of the overall Four Corners developer falling through on their responsibilities. Which inevitably caused the need for an amendment.
City Staff Recommendation: Staff acknowledges that the Commission generated good arguments but still maintains the original recommendation
to deny the amendment to condition #9 of the CUP. Staff suggests the following motion;
“Motion to adopt Resolution 2020-004 denying the Stillwater School Districts request to amend condition number 9 of their existing Condition Use Permit, for the property at 11530 Hudson Boulevard”

CITY OF LAKE ELMO WASHINGTON COUNTY
STATE OF MINNESOTA RESOLUTION 2020-004 A RESOLUTION APPROVING A REQUEST BY THE STILLWATER SCHOOL DISTRICT TO AMEND ITS
CONDITIONAL USE PERMIT (RESOLUTION 2018-77) TO OPERATE A SCHOOL DISTRICT
TRANSPORTATION CENTER FOR THE PROPERTY ADDRESSED AS 11530 HUDSON BOULEVARD NORTH WHEREAS, the City of Lake Elmo (the “City”) is a municipal corporation organized and existing under
the laws of the State of Minnesota; and WHEREAS, Stillwater Area School District, 1875 Greeley Street South, Stillwater, MN 55082 (the “Applicant”) has submitted an application to the City for an amendment to the Applicant’s existing conditional
use permit for the Applicant to operate a transportation center (bus terminal) (the “CUP”) located on the property
at 11530 Hudson Blvd N (PID# 36.029.21.43.0004) (the “Property”); and WHEREAS, by Resolution 2018-077, on July 17, 2018, the City Council approved the Applicant’s CUP to operate the transportation center on the Property; and
WHEREAS, one of the conditions in the CUP is that the Property must be connected to City sanitary sewer and water prior to the operation of the bus terminal; and WHEREAS, the Property is a part of the Four Corners 1st Addition plat that was approved by the City
Council in 2018 and a condition of the plat approval was that the developer was to construct sanitary sewer and
water facilities in order to bring sanitary sewer and water service to the Property (the “Improvements”); and WHEREAS, the developer of Four Corners 1st Addition was to complete the Improvements no later than October 31, 2019, but as of this date, construction has not commenced; and
WHEREAS, because the Improvements have not been installed and the Applicant has not been able to connect the Property to sanitary sewer and water, the Applicant requested an amendment to its CUP to amend Condition #9 of the CUP in order to allow the Applicant to operate the bus terminal on the Property using the well and septic system (septic tank and temporary toilets) either until the Applicant connects to City sewer and
water or until December 31, 2020, whichever comes first; and
WHEREAS, notice of the Applicant’s proposed amendment to its CUP has been published, mailed, and posted pursuant to the Lake Elmo Zoning Ordinance, Section 154.102; and WHEREAS, the Lake Elmo Planning Commission held a public hearing on said matter on December 9,
2019; and
2
WHEREAS, the Lake Elmo Planning Commission has submitted its report and its recommendation of approval of the amendment to the CUP to the City Council as part of a Staff Memorandum dated December 17, 2019; and WHEREAS, the City Council considered said matter at its December 17, 2019 and January 7, 2020
meeting; and NOW, THEREFORE, based on the testimony elicited, staff reports, information received, and the record presented, the City Council makes the following:
FINDINGS 1) That the procedures for obtaining an amendment to the CUP are found in the Lake Elmo Zoning
Ordinance, Section 154.106.
2) That all the submission requirements of said Section 154.106 have been met by the Applicant. 3) That Applicant’s proposed amendment to Condition #9 of the CUP consists of the following:
“[t]he School District may operate its bus terminal at the property using the well and septic system (septic
tank and temporary toilets) either until the School District connects to City sewer and water or until December 31, 2020, whichever comes first. The School District agrees to connect to City sewer and water within 30 days after it becomes available.”
4) That the proposed amendment to the Applicant’s CUP is approved for the following reasons: a) The developer of Four Corners 1st Addition has failed to install the Improvements. This failure by the developer to install the Improvements is not something that is in the control of the Applicant.
b) Properties that are within a MUSA district are required to connect to City water and sanitary sewer when they are developed. With the Property being located within a MUSA district, this standard does apply to the Property. However, with Property being a subset of the overall development of Four Corners 1st Addition, the City does not believe it is reasonable to hold the Applicant
accountable to the responsibilities of the developer. Given the requirements made of the developer
of Four Corners 1st Addition, the City fully believes that the Property will become connected to sanitary sewer and water within the near future and does not find issue with allowing the Applicant to maintain use of the existing well and septic system (septic tank and temporary toilets) on the Property until sanitary sewer and water become available.
c) The Applicant has been able to meet all of the other requirements imposed on it by the CUP. d) The City does not believe that by approving the amendment to the CUP that it will cause a burden to the City, the surrounding property owners, or the public.
3
NOW, THEREFORE, BE IT FURTHER RESOLVED, that the Lake Elmo City Council hereby approves the request by Applicant for an amendment to the CUP. Passed and duly adopted this 7th day of January 2020 by the City Council of the City of Lake Elmo, Minnesota.

Contractor shall beresponsible for all fees pertaining to this permit. The SWPPP shall be kept onsite atall times.2.Install temporary erosion control measures (inlet protection, silt fence, and rockconstruction entrances) prior to beginning any excavation or demolition work at thesite.3.Erosion control measures shown on the erosion control plan are the absoluteminimum. The contractor shall install temporary earth dikes, sediment traps orbasins, additional siltation fencing, and/or disk the soil parallel to the contours asdeemed necessary to further control erosion. All changes shall be recorded in theSWPPP.4.All construction site entrances shall be surfaced with crushed rock across the entirewidth of the entrance and from the entrance to a point 50' into the construction zone.5.The toe of the silt fence shall be trenched in a minimum of 6”. The trench backfillshall be compacted with a vibratory plate compactor.6.All areas with 4:1 slope or steeper shall have erosion control blankets placed on themwhen grading is complete.7.All grading operations shall be conducted in a manner to minimize the potential forsite erosion. Sediment control practices must be established on all down gradientperimeters before any up gradient land disturbing activities begin.8.All exposed soil areas must be stabilized as soon as possible to limit soil erosion butin no case later than 14 days after the construction activity in that portion of the sitehas temporarily or permanently ceased. Temporary stockpiles without significant silt,clay or organic components (e.g., clean aggregate stockpiles, demolition concretestockpiles, sand stockpiles) and the constructed base components of roads, parkinglots and similar surfaces are exempt from this requirement.9.The normal wetted perimeter of any temporary or permanent drainage ditch or swalethat drains water from any portion of the construction site, or diverts water around thesite, must be stabilized within 200 lineal feet from the property edge, or from the pointof discharge into any surface water. Stabilization of the last 200 lineal feet must becompleted within 24 hours after connecting to a surface water. Stabilization of theremaining portions of any temporary or permanent ditches or swales must becomplete within 14 days after connecting to a surface water and construction in thatportion of the ditch has temporarily or permanently ceased.10.Pipe outlets must be provided with energy dissipation within 24 hours of connection tosurface water.11.All riprap shall be installed with a filter material or soil separation fabric and complywith the Minnesota Department of Transportation Standard Specifications.12.All storm sewers discharging into wetlands or water bodies shall outlet at or below thenormal water level of the respective wetland or water body at an elevation where thedownstream slope is 1 percent or flatter. The normal water level shall be the invertelevation of the outlet of the wetland or water body.13.All storm sewer catch basins not needed for site drainage during construction shall becovered to prevent runoff from entering the storm sewer system. Catch basinsnecessary for site drainage during construction shall be provided with inlet protection.14.In areas where concentrated flows occur (such as swales and areas in front of stormcatch basins and intakes) the erosion control facilities shall be backed by stabilizationstructure to protect those facilities from the concentrated flows.15.Inspect the construction site once every seven days during active construction andwithin 24 hours after a rainfall event greater than 0.5 inches in 24 hours. Allinspections shall be recorded in the SWPPP.16.All silt fences must be repaired, replaced, or supplemented when they becomenonfunctional or the sediment reaches 1/3 of the height of the fence. These repairsmust be made within 24 hours of discovery, or as soon as field conditions allowaccess. All repairs shall be recorded in the SWPPP.17.If sediment escapes the construction site, off-site accumulations of sediment must beremoved in a manner and at a frequency sufficient to minimize off-site impacts.18.All soils tracked onto pavement shall be removed daily.19.All infiltration areas must be inspected to ensure that no sediment from ongoingconstruction activity is reaching the infiltration area and these areas are protectedfrom compaction due to construction equipment driving across the infiltration area.20.Temporary soil stockpiles must have silt fence or other effective sediment controls,and cannot be placed in surface waters, including stormwater conveyances such ascurb and gutter systems, or conduits and ditches unless there is a bypass in place forthe stormwater.21.Collected sediment, asphalt and concrete millings, floating debris, paper, plastic,fabric, construction and demolition debris and other wastes must be disposed ofproperly and must comply with MPCA disposal requirements.22.Oil, gasoline, paint and any hazardous substances must be properly stored, includingsecondary containment, to prevent spills, leaks or other discharge. Restricted accessto storage areas must be provided to prevent vandalism. Storage and disposal ofhazardous waste must be in compliance with MPCA regulations.23.External washing of trucks and other construction vehicles must be limited to adefined area of the site. Runoff must be contained and waste properly disposed of.No engine degreasing is allowed onsite.24.All liquid and solid wastes generated by concrete washout operations must becontained in a leak-proof containment facility or impermeable liner. A compacted clayliner that does not allow washout liquids to enter ground water is considered animpermeable liner. The liquid and solid wastes must not contact the ground, andthere must not be runoff from the concrete washout operations or areas. Liquid andsolid wastes must be disposed of properly and in compliance with MPCA regulations.A sign must be installed adjacent to each washout facility to inform concreteequipment operators to utilize the proper facilities.25.Upon completion of the project and stabilization of all graded areas, all temporaryerosion control facilities (silt fences, hay bales, etc.) shall be removed from the site.26.All permanent sedimentation basins must be restored to their design conditionimmediately following stabilization of the site.27.Contractor shall submit Notice of Termination for MPCA-NPDES permit within 30days after Final Stabilization.EROSION CONTROL NOTESGRADING NOTES1.Tree protection consisting of snow fence orsafety fence installed at the drip line shall be inplace prior to beginning any grading or demolitionwork at the site.2.All elevations with an asterisk (*) shall be fieldverified. If elevations vary significantly, notify theEngineer for further instructions.3.Grades shown in paved areas represent finishelevation.4.Restore all disturbed areas with 6” of good qualitytopsoil and seed or sod.5.All construction shall be performed in accordancewith state and local standard specifications forconstruction.6.To prevent soil compaction, the proposedinfiltration area shall be staked off and markedduring construction to prevent heavy equipmentand traffic from traveling over it. If the infiltrationfacility is in place during construction activities,sediment and runoff shall be kept away from thefacility, using practices such as diversion bermsand vegetation around the facility’s perimeter.The infiltration facility shall not be excavated tofinal grade until the contributing drainage areahas been constructed and fully stabilized. Thefinal phase of excavation shall remove allaccumulated sediment and be done by light,tracked equipment to avoid compaction of thebasin floor. To provide a well-aerated, highlyporous surface, the soils of the basin floor shallbe loosened to a depth of at least 24 inches to amaximum compaction of 85% standard proctordensity prior to planting.7.Raise grade around all hydrants to providepositive grade away from each hydrant.NOTE: INFILTRATION POND BOTTOMSHALL BE OVER-EXCAVATED DOWN TOEXISTING SAND LAYER.
