We have rev the Site Development Plans for Bremer Bank as submitted by Welman Sperides
Architects, LLC on June 20, 2007. Followin are our comments and/or recommendations,
1 The development is constructing the drive thru lane and storm sewer within the Cit utili
easement and over the existing trunk sanitary sewer and water main. Ifin the future the City eve
needs to replace/repair/maintain the trunk utilities the development will be responsible to repair all
of their items in the easement including, but not limit to pavement, curb and gutter, landscaping
and storm sewer/catch basin.
2. At crit areas such as the dri vewa y apnons and grade breaks add the percent of slope at the
drainage arrows.
3. Spot elevations should be added to the trash enclosure,
4. The e|eva the concrete drive thmisnoi clearly Identified on1heplans. Spot elevations
should be placed at each corner to show the g rade of the concrete pad.
5. Identify grades on the west side of the property in the landscaped area.
Sheet C2
1. Ve the structure size of[82. |t appears the top of the 18 inch pipe to the south will bein

2. It is assumed that the canopy for the drive thru will have footings five feet deep, If in the future
the water main requires repair in this area the footings for the canopy may be undermined.
Research the possibility of placing the water main more than 5 feet from the canopy.
3. Contact Alliant Engineering to verify the water main stub from the south that is identified by
keynote number 2. The construction plans at our office for this development does not identify a
water main stub at this location.
4. Contact Alliant Engineering to verify the sanitary stub from the north that is identified by keynote
number 1. The construction plans at our office for this development does not identify the sanitary
sewer stub at this location.
5. Insulation shall be placed at all storm sewer /water main crossings.
Sheet C3
1. The detail sheet appears to have details that will not be used. For example there was no call out
for a wet tap on the utility sheet. In addition, there are details that are missing such as a 2 x 3 box
structure that is called out on sheet C2 for structure C135.
2. A typical section for the concrete drive apron should be added to detail 13.
3. Detail 4 is a storm manhole with a 27" opening. This structure should be revised to accommodate
the Neenah casting 83067 as called out on sheet C2.
4, Add a detail showing the section for the concrete pad at the drive thru.
5. A detail is required showing the drive thru islands.
Sheet C4
1. Submit rational design calculations for the storm sewer.
Shopt ❑ l n
1, To minimize turning movements on the thru street for the overall development it is recommended
that the east driveway is narrowed and restricted to "in" movements only_ This entrance should
be signed appropriately.
2. There is a large radius on the northwest side of the drive thru lane that creates a bituminous bump
out. Is this additional bituminous really required?
3. The radius in the northeast corner appears small, Verify that all vehicles using the drive thru lane
are able to make the radius.
4. There is only 3' between the northerly drive thru lane and the existing bike path. It is
recommended that the site plan is revised to provide more distance between the bike path and the
drive thru lane.
