General Plan Review
BRA File No, 55-03-000
Dear Eric:
We have reviewed the g eneral development plans and preliminar plat
Oak Villa development as submitted b Folz, Freeman, Erickson,
followin comments/recommendations for y our consideration (previouc
applicable from our 2114103 concept plan review are shown in italics):
Preliminar Plat:
for the proposed
Inc. and have the
comments still
I Draina and Utilit Easements are re for an storm sewers, sanitar sewers or water
mains that are "public" and lie outside of public street ri Most of these are
shown, however one is re for the storm sewer north of 58th St. N. and east of Novak
Avenue N. Additionall dependin on whether sanitar sewer and water main will be public
south of Nutme Blvd. in the private drive entrance, a utilit easement ma be re there.
2. Storm sewers servin internal private streets and parkin lots will be privatel owned and

3. Additional road ri is recommended to accommodate the recommended separate
left and ri lanes on Nutme Boulevard (see Comment 7. below
4. We recommend 50' of ri be dedicated alon the west side of Oak Avenue N.
for existin and future roadwa improvements.
5. Chan the names of the streets on the preliminar plat.

6. "rhe proposed ri lane on Novak Avenue N. at 58' Street North should be extended
northerl to the future parkin lot entrance.
2335 West Hi 36 z St. Paul, MN 55113 ■ 651-636-4600 w Fax: 651-636-1311
7. We recommend Nutmeg Boulevard be designed to include separate left and right -turn lanes
at 58' Street N. This can be accommodated by increasing Nutmeg Boulevard to 40' wide
from face of curb to face of curb (expanding the west side of the road) and striping the
roadway accordingly. The road right -of -way in this area should be increased proportionately
to maintain a uniform boulevard width.
S. The proposed "drop off lane" in the public street right-of-way in front of the apartment
building on Nutmeg Boulevard should be reviewed by the Public Works Director. We
recommend either eliminating the lane and striping the curb as "loading /unloading only ", or
creating a separated off-street loop driveway closer to the entrance of the apartment building.
9. verify adequate turning radius exists for emergency vehicle access at the southeast comer of
Building No. 2 in the parking lot /driveway area. It appears the radius needs to be enlarged
and possibly resulting in losing a parking space.
10. Install temporary barricades at the north end of Novak Avenue North and at the north and
south ends of the easternmost private driveway until such time these streets are extended.
11. The proposed sidewalk on the north side of 58 Street N. shall be d' wide since it is in the
public street right -of -way and will be owned and maintained by the City. Is the construction
of this sidewalk part of the Phase 1 improvements (2004 construction)?
12. verify the proposed sidewalk to Oakgreen Avenue N. (south of future 59 "' Street N.) lines up
with the existing bituminous trail on the east side of Oakgreen Ave. N.
13. Change /update the street names in Note 1. on Sheet 2 and on the profiles on Sheet 5.
14. We recommend the future most southeasterly Townhome building be moved westerly to
access the same driveway as the Townhome on Lot 10. This would eliminate the proposed
future "double driveway" scenario and result in more overall green space,
Grading & Drainage /Storm Sewer
15. Grading will be occurring outside of the platted project area in the northwest corner. A
temporary construction easement will be required from the adjacent property owner.
16. We recommend additional silt fence be installed along the north side of 58 Street N. (both
where proposed contours drain toward the street and also to protect the existing pond from
the proposed sidewalk construction). Also, silt fence should be installed along the east side
of the site to protect the three existing residences along Oakgreen Avenue N.
17. Storm water Yunoff from the majority of this (Phase 1) development will be tributary to two
different internal ponds /wetlancls (one proposed storm water ponding area &one existing
storm water ponding area). The existing drainage pattern of the future commercial /office
area west of this phase is to the west /southwest and is in the BCWD jurisdictional drainage
area. Drainage for a majority of this area is proposed to be redirected to the east to Pond 2.
As such, formal review /approval will be needed from both the BCWD and the MSC -WMO
prior to general plan approval.
18. Storm sewers structures outletting to ponds /wetlands shall be constructed with sumps for
sediment and debris removal, for both public and private systems.
19. Storm sewers serving public streets and/or connecting trunk storm water ponds will be
considered public and owned and maintained by the City. Public storm sewers will be
designed by the City and included in the public improvements bid documents. The following
storm sewer lines will be considered public for this development:
i Stub west of CBMH 148 to FES 142 (excluding CBMH 146 to MH 144)
0 CB 144 to FES 112
0 Inlet 132 to MH 119
0 CB 124 to FES 115 (excluding CB 118 to MH 116)
0 Inlet 102 to Existing MH SS -2
All other storm sewer lines are considered private and will be owned and maintained as such.
All private storm sewer design data (pipe slopes and material, structure sizes & rim and
invert elevations, profiles, etc.) should be shown on the plans.
20. Storm water runoff /ponding calculations and storm sewer design calculations will be
reviewed and commented on separately, to verify adequate pond storage capacities and
ultimate offsite discharge rates.
S anitary Sewer
21. The sanitary sewer layout, in general, is acceptable. The reach from MH 1 to MH 4 may be
better located within the future 59 Street N. ali and should be verified with the
public works department. Also, due to existing site elevation differences, the sanitary sewer
alignment to serve the easterly town homes proposes to go under the storm water pond. This
is not a desirable situation, but the pipe is proposed to be encased for this reach.
22. Typically, sanitary sewers under public streets are considered public and owned and
maintained by the City. In this case, the City will be deciding whether the reach from
connecting to the existing stub by the oakgreen Townhomes (Hom4MC) to MH 6 will be
public (since serving as a "regional" line) or private. All other sanitary sewer lines are
considered private and will be owned and maintained as such. All private sanitary sewer
profiles should be shown on the plans.
23. Show the existing line north of the proposed connection (along the west side of oakgreen
Avenue N.) as a thinner, existing line.
W ntpl.1\4pill
24. The water main layout, in general, is acceptable. The overall alignment, hydrant locations
and main line valve locations (none are shown) should be reviewed with the City Public
Works Director and Fire Department. As with the sanitary sewer, the reach adjacent to
future 59 Street N. may be better located within the future street alignment.
25. The proposed 12" main line in Novak Avenue N. will be publicly owned and maintained.
The City will be deciding whether other reaches of water main (connection to existing main
by Pondview Condominiums to future 59 St. N.; line along the south side of future 59
Street N.; and the line from future 59 Street N. down to south of Nutmeg Blvd) will be
public or private. All other water mains are considered private and will be owned and
maintained as such.
26. Fire hydrants shall incorporate an AFC - Waterous Storz Nozzle. The hydrant pumper
nozzle shall be of one -piece design, compatible with a 5" Storz hose coupling. The nozzle
shall be an integral part of the fire hydrants and must be furnished by the manufacturer or
authorized distributor designated by the manufacturer. Storz adapters will not be accepted.
27. We recommend any close water main and storm sewer crossings be insulated, and where
CBs or CBMHs fall on top of (or close to on top o� water mains in the private streets.
