FILE NO: 798.04 — 08.03
BACKGROUND
Randy Engel, representing Buetow and Associates, has made application on behalf of
the City of Oak Park Heights for the construction of a new City Hall building and
expansion of the Public Works facility. 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 0, Open Space Conservation in which city halls and their
accessory structures and uses are a listed permitted use.

Comments of the City Arborist
Comments of the City Engineer
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 Plan were adopted by the City Council at its December
23, 2008 meeting. The new City Hall and Public Works facility improvements will be
conforming with the Comprehensive Plan.
Zoning. The City Hall and surrounding open areas are zoned 0, Open Space
Conservation. Municipal structures and buildings, as well as parks and recreational
facilities, are a listed permitted use. The Public Works facility and water pump house
are existing accessory structures on site.

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. "

Parking Stalls Provided
56 stalls
8 stalls

Section 40t .15. F.0.00 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
l� p p 0 Y
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
proposed by lot
and is ro osed to be 40 feet b 74 feet. It will also be enclosed with an eight foot
solid fence. The 0 ate 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 p ermit for the open storage areas. The areas will be adequately
screened by a solid fence, existing trees and landscaping.

Intensity. The submitted photometric plan meets the Zoning ordinance requirements
for lighting intensity.
Location. The ordinance requires the Tight 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 0 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, signage the si e shall be subject to approval of City staff. The City may also
p g
decide to add additional directional signage at the first traffic circle to direct vehicles to
the City Hall and the parking areas.

Revised Landscape Plan OPH City Hall Project
I have reviewed the revised landscape plan for the new OPH City Hall project. Changes have been made regarding the
potential problems I pointed out in my review of 12/18/08. These changes include moving the trail away from the existing
large oak SW of the Pub. Works Bldg., changing oaks specified on N and S ends of main entrance walkway to a smaller
statured tree (Jap. tree lilac) because of constricted rooting areas, and adding language regarding removal of twine and
upper courses of wire basket from root ball prior to filling in planting hole. 1 accept these changes to the plan and planting
detail.

OPH Staff -
1 have reviewed the site and landscape plans submitted for the construction of the new City Hall. I have the following
comments, most of which 1 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' spires, 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. 1 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.

OPH City Hall Landscape Plan & Tree Protection
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 1 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 1/3 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)
1 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.

Re: City Hall Site
Plan Submittal
Bonestroo File No.. 55 /gen
Dear Eric:
We have review the plans dated December 12, 2008 for the City Hall Site as submitted by
Buetow & Associates. Following are our comments and/or recommendations,
DRAWING C1
1. Call out number 12 is shown on the existing building; however, it is not identified in the
Demolition Key Notes.
2. The existing water service at the south end of the existing building is in bold print, but it
is not identified with a call out,
3. The City Arborist should provide comments/recommendations in regards to the tree
removals.
DRAWING C2
L Drain tile shall be placed in any pavement sections that have a sand subbase.
2. Consider adding a walk/pathway around the north /northeast side of the proposed PW
storage yard to connect to the sidewalk to city hall. This will provide pedestrians from
the Pine Grove Gardens area a more direct access to city hall.
DRAWING C3
L Show drainage arrows and label percent slopes.
2. Identify the slopes as ratios in the pond area and other restored areas (ex. 4 :1).
3. Identify the locations of the emergency overflows.

4. Provide more grading detail /spot elevations at the following locations:
-Trash enclosure
- Sidewalks (cross slopes)
- Curb cuts at pedestrian ramps.
- Concrete stoops

5. 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 %. Is it possible to flatten
this grade?
DRAWINGS C5
L 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 tile 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 Class 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.
