As part of this proposal, Mr. Regan has negotiatedwith the parks department to share parkingfacilities and to utilize some of the park land for the parking lot. A similar arrangement had been approved in 2011 for a previously proposed medical building which was never built. The requirements outlined in the city’s parking requirements make it impossible for the applicant to fit everything within his site, thus the negotiations with the city’s parks department. The property is guided in the city’s comprehensive plan as Commercial (C) and zoned as Limited Business Commercial (LBC), which allows for offices, medical or health-related clinics, day care centers, or similar uses. Requests To build this development, the applicant isrequesting the following city approvals: 1.Design plans Background December 11, 2006:The city council approved a lot division to split this site from the Walgreens to the west. September 26, 2011: The city council approved design plans, a public vacation and a reciprocal easement agreement. Because more than two years have lapsed the design approval is not valid anymore, but the public vacation is a permanent approval and still valid. The city council will be considering a revised reciprocal easement agreement as negotiated by the parks department. 1 Discussion Design Review Curb Cuts/Driveways The current site does not have a curb cut. The parking lot serving Maplewood Heights Parkdoes have a curb cut. The proposed site plan will have one curb cut off of Beam Avenue with the park and medical buildings sharing parking facilities. The city and Mr. Regan will need to execute an easement agreement outlining the terms of the shared access and parking facilities. There will be an additional access point fromthe access road on the Walgreens property. Sidewalksand Trails There is an existing six-foot-wide concrete sidewalk located along BeamAvenue. There will be an internal concrete sidewalk to serve the building. There will also be a five-foot- wide concretetrail on the east side of the site connecting the sidewalk along Beam Avenue and the parking lot to the ring trail around the pond within Maplewood Heights Park. There is a proposed retaining wall on the east side of the site which will work to keep the grades of the trails and sidewalks accessible. For retaining walls more than four feet in height a fence on the top is required by building code. Staff is recommending a fence be installed on top of the retaining wall regardless of the final height because of the proximity of the nearby tennis and basketball courts. Site Layout The building and parking lot meet or exceed required setbacks of 30 feet and 15 feet to the right-of-wayrespectively.The proposed drive aisle through the parking lot meets the city minimum requirement of 24 feet. There is a small portion of unused right-of-way between the applicant’s parcel and the city park parcel that wasvacatedin 2011. Parking City code requires medical office buildings to have one parking stall per 200 square feet of office space. The proposeddevelopment requires 70parking stalls based on this requirement. The applicants are proposing 70parking stalls, which includeseight handicap accessible stalls. The parking stalls will be 9.5feet wide by 18 feet deep, which meets city code requirement for a medical office (lowturnover) use.In addition to the 70 stalls for the medical building, four stalls are proposed to beexcusive for the park. These stalls will have signs indicating for park use only. The current park parking lot has 10stalls but the city’s parks department staff is comfortable with having four stalls exclusively assigned to the park because of the amount of street parking nearby and the ability for park goers to use other parking spaces at the medical building during non- business hours. The official shared parking agreement between the city and Mr. Regan will be memorialized through aneasement agreement. Landscaping The landscape plan shows 25trees, including 13 overstory deciduous trees, and various shrubs.The plan reflects trees being planted every 30 feet along Beam Avenue, which 2 was a requirement of the 2011 approval. The plan also calls out underground irrigation for all landscaping as required by code. Staff is comfortable with the layout and design of the internal site landscaping. Lighting City code requires the submittal of a lighting and photometrics plan which ensures all freestanding lights maintain a height of 25 feet or less and that the maximum foot candles of illumination at all property lines doesnot exceed .4-foot-candles. The submitted photometrics plan shows the applicant exceed the .4-foot-candles code requirement. The applicant shall resubmit a plan that meets code requirements. Trash Handling The applicant has indicated all trash facilities will be located within the building. If at any time trash facilities are located outside of the buildingitwill need to be located within an enclosed structure which must be approved by the city. Building Elevations The exterior of the building will be constructed with face brick, EIFS and clear anodized aluminum windows. The building elevations also propose a 18’8”-foot-high entryway with precast architectural panels. Staff finds the proposed buildings elevations to be an attractive design. DepartmentComments Fire Department: Butch Gervais, fire marshal, reviewed the development proposal and has the following comments: Must comply with all fire codes, installing fire protection, system monitoring and notification inside the building. Fire department key box order form provided by Fire Marshal. Engineering Department: Jon Jarosch, staff engineer, has reviewed this project. Mr. Jarosch’scomments and requirements are attached to this report. Recommendations 1.

The applicant is requesting a review of the current design. As the amount of disturbance on this site is greater than 0.5 acre, the applicantis requiredto meet the City’s stormwater quality, rate control, and other stormwater management requirements.The submitted stormwater management plan depicts the project meetingthe City’s requirements as it pertains to infiltration and rate control. This review does not constitute a final review of the plans, as the applicant will need to submit construction documents for final review.Thefollowing are engineeringreview comments on the design and act as conditions prior to issuing permits. Drainage and Stormwater Management 1)The project shall be submitted to the Ramsey-Washington Metro Watershed District (RWMWD) for review. All conditions of RWMWD shall be met. 2)The applicantis proposingthe use ofinfiltrationto meet water quality requirements.As such, the applicant shall submit copies of geotechnical information (soil borings, infiltrations tests, etc.) to support the infiltration rates shown in the hydraulic calculations. 3)The infiltration rateutilized for the underground infiltration system in the storm-water management report is 0.05 inches per hour and is inadequate to meet the 48-hour drawdown requirement. The applicant shall verify that the infiltration rate utilized is correct. It may be necessary to adjust the design to ensure draw down within a 48 hour timeframe. It should be noted that the maximum depth allowed for infiltration practices is 2-feet. 4)The applicant shall provide storm sewer pipe sizing details for all onsite storm sewer. 13 Attachment 7 5)There are a number of storm sewer pipes shown on the plans to have a slope of 0.3%. City standards require a minimum slope of 0.5%. These pipes shall be revised to meet this requirement. 6)Emergency overland overflows shall be identified on the plans for thelow-point in the parking-lot.Similarly, the high-water level (HWL) and normal water level (NWL) shall be noted on the plansfor the underground infiltration system. 7)If the underground infiltration system does not contain an integrated pre-treatment system, a sump-manhole or other pre-treatment device shall be installed immediately upstream of the system. 8)A 12” storm sewer stub is currently shown near the building entrance. The applicant shall detail what the intended purposeis for this stub. 9)The applicant shall provide computations showing the proposed cut and fill within the 100-year HWL of the adjacent pond to ensure no detrimental impact will occur as a result. Grading and Erosion Control 10)All slopesshall be 3H:1V or flatter. 11)The proposed infiltration areasshall be protected from sedimentation throughout construction. 12)Inlet protection devices shall be installed on allexistingand proposedonsite storm seweruntil all exposed soils onsite are stabilized. Additionally, storm sewer inlets along adjacent City and private roadsshall be protected throughout construction. 13)Adjacent streetsshall be swept as needed to keep the pavementclear of sediment and construction debris. 14)All pedestrian facilities shallbe ADA compliant.This includes the proposed pedestrian ramp and walkway on the Park property at the east end of the project. 15)A copy of the project SWPPP and NDPES Permit shall be submitted prior to the issuance of a grading permit. 16)Stabilized construction entrances shall be placed at all entry/exit points to the site, including the access off of Beam Avenue. 17)The total grading volume (cut/fill) shall be noted on the plans. 14 Attachment 7 18)All emergency overland overflows shall contain adequate stabilization to prevent soils from eroding during large storm events. 19)The proposed retaining wall at the east end of the project will require an engineered design as well as a building permit. 20)The landscaping plan depicts a planting bed within the emergency overflow area on the north side of the development. Likewise, this planting bed is proposed to be placed on top of an existing storm-sewer pipe. The plan shall be revised to ensure the emergency overflow elevation is not compromised and that plants do not block the emergency overflow path. Please note that planting within the storm-sewer easement is done at the applicants risk. Should future storm-sewer work within the easement be necessary, plants in this area could likely be damaged or destroyed. 21)Adequate scour protection shall be provided at all curb-cuts that allow runoff to enter the proposed raingarden. It is advised that this scour protection be extended to the bottom of the garden to minimize erosion and future maintenance issues. 22)The raingarden detail depicts a 36” depth of engineered soil containing 70% sand and 30% compost. There is some concern that plants will find it difficult to establish in this depth of engineered soil. The applicant should consider reducing this soil depth to ensure plant roots can reach the underlying soils. 23)Rain Garden Plantings. a.A large portion of the infiltration basin has no plants. Please indicate what plant material will in the bottom of the basin. b.Two species on the rain garden slope (lilac and juniper), don’t handle standing water so will probably not do well on the bottom of the slope. You may want to consider a more water tolerant species for the row of plants along the bottom of the rain garden slope. 24)Plant selection. Please substitute another shrub for the barberry. Barberry is beginning to become invasive in our area. Sanitary Sewer and Water Service 25)Sanitary sewer service piping shall be schedule 40 PVC or SDR 35. 26)The proposed water service modifications are subject to the review and conditions of Saint Paul Regional Water Services(SPRWS). The applicant shall submit plans and specifications to SPRWS for review and meet all requirements they may haveprior to the issuance of a grading permit by the City. 15 Attachment 7 27)The applicant shall provide fixture unit computations verifying that the sewer service is adequate for the proposed building. 28)The applicant shall be responsible for paying any SAC, WAC, or PAC charges related to the improvements proposed with this project.
