The application consists of requests for a conditional use permit for open and outdoor storage, a conditional use for proof of parking, a conditional use permit for building height, site plan, and Design Guidelines review. The project is to be completed in two phases, the first to construct the City Hall and Public Works expansions, outdoor storage areas, and associated driveway. The second phase would involve demolition of the existing City Hall building and construction of the entry driveway, traffic circle, and much of the parking adjacent to the new building. The property is zoned O, Open Space Conservation in which city halls and their accessory structures and uses are a listed permitted use. Attached for reference: Exhibit 1: Plan Cover Sheet (A0.0) Exhibit 2: Boundary and Topographic Survey (02.01) Exhibit 3: Demolition Plan (Cl) Exhibit 4: Paving Plan (C2) Exhibit 5: Grading Plan (C3) Exhibit 6: Erosion Control Plan (C4) Exhibit 7: Utility Plan (C5) Exhibit 8: Engineering Details (C6) Exhibit 9: Engineering Details (C7) Exhibit 10: Landscape Plan (1-1.0) Exhibit 11: Site Plan (A1.0) Exhibit 12: City Hall Existing Floor Plan (A2.0) Exhibit 13: City Hall Proposed Lower Level Floor Plan (A2.1) Exhibit 14: City Hall Proposed Main Level Floor Plan (A2.2) Exhibit 15: City Hall Proposed Roof Plan (A2.3) Exhibit 16: Public Works Proposed Floor Plan (A2.4) Exhibit 17: Public Works Proposed Roof Plan (A2.5) Exhibit 18: City Hall Exterior Elevations (A3.0) Exhibit 19: City Hail Exterior Elevations (A3.1) Exhibit 20: Public Works Exterior Elevations (A3.3) Exhibit 21: Lighting Plan (EP1) Exhibit 22: Comments of the City Arborist Exhibit 23: Comments of the City Engineer PROPOSED PROJECT The City Council, in May 2008, passed a resolution authorizing the issuance of bonds to fund the construction of a new City Hall facility which will replace the 35 year old building located at 14168 Oak Park Boulevard. A Citizens Advisory Committee was appointed by the City Council to look at options and provide recommendations on the building and facility needs of the City. The project architect, Buetow and Associates, and the project engineer, Larson Engineering, have provided site and building plans for review. The project will require a conditional use permit for open and outdoor storage, for building height, for proof of parking, as well as site plan and Design Guidelines review. The footprint of the new City Hall will include 13,640 square feet on the first floor and 11,697 square feet on the lower level. It will include offices for City Administration and the Police Department, meeting space, a Council chambers, storage space, and garage space in the lower level. The Public Works garage will be expanded to a 5,996 square foot facility. The existing City Hall will be demolished. Of that building, a 484 square foot water pump house will remain. The site and grounds will be updated with new parking, trails, and landscaping. A Public Works storage area and a City impound lot will be located at the west side of the site and are to be totally enclosed by fence and landscaping. ISSUES ANALYSIS Comprehensive Plan. The Proposed Land Use Map of the 2008 Comprehensive Plan indicates the City Hall property and the area to the north as Government Facilities. The 2 map and the Comprehensive Cit nH were d the City facility its December 23, 23, 2008 meeting. The new y conforming with the Comprehensive Plan. Zoning. The City Hall and surrounding open areas are zoned O, Open Space Conservation. Municipal structures The buildings, as well as Works facility and k water d pump house facilities, are a listed permitted use. are existing accessory structures on site. Area and Building Size Requirements. City Hall Property — O, Open Space Conservation Required Lot Area 5 acres Existing Lot Area 17.8 acres Required Lot Width — 200 feet Required Hei ht 35 feet Existing Lot Width 200 feet ... Proposed Building Hei ht Main Structure — 24 feet Rotunda — 40 feet City Hall Property — O, Open Space Conservation SETBACKS — CITY HALL Re uired Front Yard Proposed Front Yard 50 feet City Hail — NA Re uired Side Yard 30 feet Proposed Yard 30 feet ... on all sides Required Rear Yard 50 feet Proposed Rear Yard 300 feet ++ SETBACKS - ACCESSORY BUILDING — PUBLIC WORKS GARAGE Required Side Yard 5 feet Proposed Side Yard 35 feet (west) Required Rear Yard 8 feet Proposed Rear Yard 400 feet ++ SETBACKS — PUBLIC WORKS STORAGE AND CITY IMPOUND LOT Re uired Side Yard Proposed Side Yard 10 feet Public Works Storage — 20 feet City Impound Lot — 23 feet 3 The new City Hall building, the addition to the Public Works facility, the Public Works storage, and City impound lot will meet all Zoning Ordinance setback requirements. Parking. City halls are considered as office buildings for the purpose of calculating parking requirements. The Zoning Ordinance requires "three (3) spaces plus at least one space for each two hundred (200) square feet of floor area." Main Level Lower Level (Parking Area Subtracted) Total 13,640 square feet 11,697 square feet 25,337 square feet 25,337 X .9 W 22,803 - 200 = 194 + 3 = 117 parking spaces required The site plan indicates the following parking to be provided: Surface Parking 56 stalls Parking Garage 8 stalls Proof of Parking 54 stalls Parking Stalls Provided 118 stalls Section 401.15,F.9.00 of the Zoning Ordinance allows the City Council to approve a site plan with proof of parking by conditional use permit. The site plan indicates the area that has been reserved for the 54 stalls of proof of parking. If the stalls are needed in the future, the parking area can be expanded to meet the demand at that time. The site would require five accessible parking stalls. The site plan indicates five accessible stalls, all of which are van accessible. Open and Outdoor Storage. Open and outdoor storage is allowed as a conditional use permit in the Zoning Ordinance. The City impound lot will be located on the west side of the City Hall site. It will be enclosed with an eight foot solid fence constructed of a Trex composite wood. The area will be 72 feet by 65 feet and accessed by a gate on the south side. The Public Works storage area is located to the south of the impound lot and is proposed to be 40 feet by 74 feet. It will also be enclosed with an eight foot solid fence. The gate would face east. Both of the enclosure areas would be landscaped, especially to the west, adjacent to the existing Pine Grove Garden development. Additionally, there are existing trees that will provide screening, especially for the Public Works storage area. City staff has reviewed the list of conditions for a conditional use permit found in Section 401.03.A.7 of the Zoning Ordinance and finds no adverse effects of granting the conditional use permit for the open storage areas. The areas will be adequately screened by a solid fence, existing trees and landscaping. 4 Site Access /Trails. The site will be accessed via Oak Park Boulevard, a two -way street, and west bound only from O'Brien Avenue just as it is today. Vehicles entering the site will be able to enter a parking area and the City Hall from both access points from a traffic circle. The Public Works facility and the lower level of the City Hall would be accessed off a separate entrance off of Oak Park Boulevard. The City Hall is provided with a main parking area and another traffic circle which allows for disability parking, short term parking, and a drop off area. The driveways and turnaround area design shall be subject to review and approval of the Police Chief and Fire Marshal. Trail access through the site will be re- routed to accommodate the new building, parking areas, and driveways. The trail from Oak Park Boulevard will extend through the site to the east side and up to the existing trail. A trail access will also be provided to the Pine Grove Garden neighborhood to the west. A sidewalk will extend from the front of City Hall, to the drop off area, the parking area, and to the rear of the Public Works building. Impervious Surface /Rain Garden / Stormwater. The total impervious surface coverage of the site after construction will be 15 percent. A large rain garden is incorporated into the drainage plan and it will be located just to the west of the City Hall building. The stormwater plan for the project is subject to review and approval of the City Engineer and the Middle St. Croix Watershed Management Organization. Utilities. A utility plan has been submitted and shall be subject to review and approval of the City Engineer. Trash /Generator Enclosure. The trash /generator enclosure servicing the City Hall and Public Works would be located on the north side of the Public Works garage. The enclosure would be constructed of the same brick as is used on the garage and on City Hall. Metal gates would be provided on both the west and north sides. City staff suggests that the enclosure be moved approximately five feet to the west in order to allow landscaping on the east side of the enclosure. This may depend on the location of a fiber optic line in this area. The landscaping would reduce the visual impact of the enclosure from the City Hall and parking area. Lighting Plans. Fixtures. The submitted photometric plan indicates 14 freestanding fixtures on 16 foot poles with 36 inch concrete bases. A final fixture design has not been determined, but it will likely be a hat box or shoe box design that is fully cut off. City staff suggests eliminating the 36 inch concrete bases wherever possible, by placing the fixtures further from the curb and using taller poles if necessary. The maximum height above the ground grade permitted for light sources mounted on a pole is 25 feet. Lighting is also proposed under the soffit of the building. The final design of these lights and their locations have not been determined but the fixtures will be fully recessed. Wi Intensity. The submitted photometric plan meets the Zoning Ordinance requirements for lighting intensity. Location. The ordinance requires the light source of an outdoor light fixture to be set back a minimum of five feet from an interior side lot line. All of the proposed fixture locations would meet this requirement. Hours. Outdoor lighting for parking lots shall be turned off one hour after closing, except for approved security lighting. Landscape Design. The landscape plan shall be subject to approval by the City Arborist. The comments of the City Arborist are found as Exhibit 22. In addition to those comments, please find comments of City staff: Rain Garden. The rain garden element is an effective way to treat stormwater runoff in addition to educating the public. These gardens are not only aesthetically pleasing but functional as well. This might be a great opportunity to add an interpretive signage element that outlines educational and interesting rain garden /stormwater facts. Traffic Circles. The two traffic circles give opportunity for a vertical element, whether that be landscaped or public art. According to AASHTO Roundabout Design Guidelines, center landscaping is an important part of a roundabout design to provide visual awareness of the traffic circle. The available space in the center would allow for perhaps a hardy ornamental tree and shrubs, flag pole or public art piece, or any combination of all three. Bollards. The traffic circle bollards could be enhanced aesthetically from the currently specified concrete filled tubes. There are several examples of "off the shelf" catalog bollards that include interesting metal work in a variety of colors and shapes. Trash Enclosure. The trash enclosure located south of the rain garden could be shifted to the left to allow additional space for landscaped elements in front of the trash enclosure wall. This would screen an otherwise vertical blank trash enclosure wall. Signs. The building plans indicate only one wall sign at the front of the City Hall building. The sign reads" City of Oak Park Heights" and is a total of 25 square feet. The signage for a public facility in the O District is not allowed to exceed 60 square feet. The sign will be lilt with ground mounted directional fixtures in accordance with the Zoning Ordinance standards. Additional directional signage may be added to the Public Works building. When proposed, the signage shall be subject to approval of City staff. The City may also decide to add additional directional signage at the first traffic circle to direct vehicles to the City Hall and the parking areas. Building Type and Construction. 1d l Quality. The proposed City Hall building meets the quality standards of the ordinance, which states that buildings in all zoning districts shall maintain a high standard of architectural and aesthetic compatibility with surrounding properties to ensure that they will not adversely impact the property values of the abutting properties or adversely impact the public health, safety, and general welfare. Colored building elevations will be provided at the Planning Commission and City Council meetings. The exhibits, as attached, provide detailed elevations with all of the material types identified. Exterior Finishes. The exterior of the City Hall structure will feature a stone veneer at the front entrance with a majority of the building covered in brick. A rotunda feature will emphasize the front entrance. There is significant detailing in the brick and around the windows that breaks up the larger facades. The windows will be a pre - finished aluminum window system and the roof a metal standing seamed system. The final exterior colors of the building have not been finalized, but the initial material selections have been neutral colors that are consistent with the Design Guidelines. All exterior colors will be subject to review and approval of the City Council. The Public Works garage and the water pump house are to be resurfaced in the same brick as used for the City Hall. Mechanical Equipment. All of the mechanical equipment for the City Hall and Public Works facility shall be enclosed in the building structures or enclosed by screening walls. Building Height. For principal buildings (City Hall), the building height maximum allowed in the O District is 35 feet. For accessory buildings (Public Works), the building height is 17 feet with the approval of the Building Official. The main City Hall building will be 24 feet in height when measured from the medium building elevation at the ground to the mid point of the gabled roof. The building height measurement is compliant with the Zoning Ordinance. The rotunda is 40 feet to the peak of the roof from the medium building elevation. The Zoning Ordinance requires a conditional use permit if a structural element of the building exceeds the maximum height of the building by more than five feet. The rotunda element is about eight feet above the ridge of the building and 16 feet above the measured height of the building, A conditional use permit is required for the rotunda element. City staff has reviewed the requested building heights in light of the requirements for a conditional use permit found in Section 401.03.A.7 of the Zoning Ordinance, and finds no adverse impact of granting the conditional use permit for the building height. The additions to the Public Works building will be 16 feet in height. The existing water pump house is 11 feet in height. There are no height issues with either of the accessory buildings. 7 RECOMMENDATION AND CONCLUSION Based upon the preceding review, City staff recommends approval of the conditional use permits for open and outdoor storage, for proof of parking, for building height as well as approvals of the site plan and Design Guidelines review subject to the following: 1. The City Council shall approve the final materials and colors of the fencing and gates for the City impound lot and the Public Works storage area. 2. The driveways and traffic circle design shall be subject to review and approval of the Police Chief and Fire Marshal. 3. The stormwater plan for the project shall be subject to review and approval of the City Engineer and the Middle St. Croix Watershed Management Organization. 4. The utility plan shall be subject to review and approval of the City Engineer. 5. The trash /generator enclosure shall be moved approximately five feet to the west in order to allow additional landscaping. The final location of the enclosure is subject to the location of a fiber optic line. 6. The City Council shall approve the final fixture design for the parking lot lights. The concrete base heights shall be minimized to less than one foot in height. 7. The City Council shall consider options for the two traffic circle islands, including trees, landscaping, flag poles, or public art piece. 8. The traffic circle bollards shall be of a decorative design. 9. The City Council shall determine the final building design, materials and color selection. 10. The landscape plans shall be subject to review and approval of the City Arborist. 11. Any additional signage proposed for the site or buildings shall be subject to review and approval of City staff. 12. Any other conditions of the Planning Commission, City Council, and City staff. 8 eMmAmmml— jvjjjwqnS —mv A I'll 1� =`... 1.1, . 1 .

Widin [kdwidin @comcast.net] Sent: Thursday, December 18, 2008 8:28 AM To: Eric Johnson; Mark Vierling (E- mail); Dennis Posher (E- mail); Scott Richards; Jimmy Butler; Judy Holst; Julie Hultman; Tom Ozzello; michaellueth @buetowarchitects.com Subject: OPH City Hall Landscape Plan & Tree Protection OPH Staff - I have reviewed the site and landscape plans submitted for the construction of the new City Hall. I have the following comments, most of which I shared at the site review meeting yesterday: 1. The site plan shows one large oak in the SW corner of the project (N of the entrance road) to be removed and the other to be saved. The plan also shows a curb on one side and a trail on the other side, both within the branch spread of the tree to be preserved. Having excavation and construction activity within the branch spread will make it difficult to save the oak. In the meeting, re- routing of the trail was discussed, and this would help a lot. Also, any additional distance that the curbing can be moved away from the trunk on the NE and E sides would be good. 2. The plant material chosen for the landscaping looks good. Most are native or improved cultivars of native plants. One exception is 'Little Princess' spirea, but this is an excellent landscape plant, so that will work for this project. 3. The design overall looks good, and will complement the site and building. The use of a rain garden near the building will not only help with runoff from the site, but will be a good educational piece for residents and others visiting City Hall. 4. l commend the use of oaks in the landscape plan (Oak Park Hts.), but recommend a couple things: a. the oaks are currently shown in rows - this would be an issue if one of them contracted oak wilt disease, which spreads by root grafting underground, as well as by insect transmission to fresh wounds in the spring. Alternating the oaks with another species would probably be better from the disease standpoint. I understand the design concept, and the situation of oak wilt in these trees is a long shot, particularly if the oaks are not pruned during April 1 -July 1, the most susceptible period for insect transmission. I mention this possibility as a plant pathologist, and to make the City aware of all issues; however, I will not reject the plan if the oaks remain as depicted. b. the oaks at the south end of the walkway from the entrance to City Hall are shown planted in an area possibly 15 ft, in diameter or less, due to infrastructure. This size area is too confining for the root system of the oaks and smaller stature trees, shrubs, or perennials/grasses should be planted in these locations instead of large stature trees such as oaks. c. the trail on the east side of the City Hall comes down to the entrance road and also will constrict the rooting area of oaks planted on the east side of the entrance sidewalk, especially the southernmost ones mentioned in 4b. 5. Planting Detail - this looks o.k, except that I would like to see points in the diagram added: a. twine should be removed from base of trunk and top of burlap pulled back before back - filling b. the top of the wire basket (if any) on the root ball of B &B material should have the top 113 removed before back - filling the planting hole (planting method will be checked and trees will need to be re- planted if 5a & 5b are not completed before planting) I have forwarded the Tree Protection Standards for OPH to Mike Lueth. These describe the requirements for tree protection during construction. If you have any questions regarding this review or report, please contact me.

Provide more grading detail/spot elevations at the following locations: -Trash enclosure Sidewalks (cross slopes) Curb cuts at pedestrian ramps. - Concrete stoops At the southwest corner of the impound lot the proposed grade is 948.18 and the elevation to the east is at 947.0 for a slope of approximately 8 0 /6. Is it possible to flatten this grade? DRAWINGS C5 1. The slope on the sanitary sewer shall meet the Minnesota State Plumbing Code 4715.2400. For an 8" pipe the required slope is 0,52% 2, As discussed above, drain the shall be placed in pavement sections with a sand subbase. At a minimum, the drain tile shall be placed at the low points and extend 20 feet in each direction from the catch basin. 3. The storm water reports states that there are Type D soils in this area. Will there be drain tile around the footings of the structures? If so, show elevation of the drain tile, locations and discharge locations. 4. Insulation shall be placed at all water main/storm sewer crossings. 5. Verify with the Public Works director that the submerged pipe on the outlet structure is acceptable. If the submerged pipe is approved it should be increased to 21" to provide area for sediment build -up. 6. Provide a separate submittal that identifies the drainage path of the pond discharge. Verify that the storm water is not impacting any commercial or residential areas. 7. Under Note 5 the class of RCP shall be changed to Gass V for all 12 ", 15" and 18" RCP. 8, Under Note 11 it should state that any DIP sanitary sewer shall be poly lined. 9. Note 14- The City of Oak Park Heights does not officially have standard specifications; therefore specifications will be required for this project. GENERAL COMMENTS 1. The drawings are missing items such as structure/invert elevations, callouts, structure schedule, details, etc... A more detail review will be performed as the construction documents progress. 2. The following items should be submitted for review: Rational Calculations for storm sewer. Response comments from Middle St. Croix Watershed Management Organization Final Geotechnical Report 3. The storm water report discusses a Bio- Retention Basin. Where is this located on the site? 4. Verify with the Middle St. Croix Watershed Management Organization that the proposed 9600 cf discharge into Wetland C is acceptable.
