The approach slopes for the alley at the intersection with Laporte Avenue exceed the 2.0% minimum.
RESPONSE: I understand that 2.0% is the minimum cross slope, not the minimum longitudinal slope.
Please provide all vertical curve information.
RESPONSE: Done.
Please label the curb cuts on the profile.
RESPONSE: Done.
Please show the alley flowline profile to Maple Street.
RESPONSE: Done.
Please label the curb and gutter to be constructed.
RESPONSE: Done.
Add Note #3: A typical cross section for the alley is shown on sheet 9XX).
RESPONSE: Done.
Street Sections; Sheet 11 of 15
Please show the cross sections to the back -of -walk. I need to see.this in order to see. if the cross slopes for
the sidewalk meet the '/,' to %z' per foot requirement.
RESPONSE: Done.
- The maximum allowable cross slope is 4.0% (Section 1.02.0312c). (Please look at all the possibilities for
the cross slopes and the flowline slopes to determine if the design can comply with the street standards. If
any variances are needed to the street standards, contact me (Mark CcCallum) at 221.6605);
RESPONSE: Done..
Please label all cut and patch work on the cross sections.
RESPONSE: Done.
Detail Sheet; Sheets 13,14 & 15 of 15:
Please provide the following details:
1. Driveway detail for the Mason Street access. (This detail should be a modified version of Detail D-15)
2. Enhanced crosswalk detail
3. Roll over curb and gutter detail for the alley
4. Typical Mason Street and alley detail
Please provide more detail for the existing storm manhole replacement detail. Three questions that should
be answered:
1. Is there enough distance between the bottom of the curb section and manhole barrel section?
2. Does the adjustment to rim and manhole cover exceed 16"?
3. Does the manhole conflict with the access ramp? Perhaps a "blow-up" of the access ramp will provide
this information.
RESPONSE: Done.

Dear Mr. McCallum:
Following are our responses to your comments regarding your review of our submittal for the Civic Center
Office Building. Your Comments followed by Response:
Horizontal Control and Pavement Plan; Sheet 4 of 15:
Please show existing -and approved design for the comers of Mason Street with Laporte Avenue and Maple
Avenue. In particular, please show enhanced cross walks and access ramps. Please specify which access
ramps are to be built as the result of this project.
RESPONSE: The design by Icon is now shown for these comers. As noted on the plans and in earlier
written response to review comments, there are no enhanced crosswalks being constructed with this project.
Please provide a turn around for the dead end parking spaces.
RESPONSE: Done.
Utility Plan; Sheet 7 of 15:
Please relocate the storm drain manhole so that it is not in the access ramp or provide more information for
review as requested on sheet 14.
RESPONSE: The ramp has been revised so that the manhole is no longer in the ramp.
Add Note #3: All -streets cuts, curb & gutter and sidewalk removal, and the repair & reconstruction of the
aforementioned shall be done in accordance with the city's "Street Repair and Reconstruction Standards
and Guidelines." The city inspector and/or the City Engineer shall have final authority in regards to the
limits of the street repair.
RESPONSE: Done.
Mason Street Plan and Profile; Sheets 9 & 10 of 15:
Please provide curve data for all curb returns.
RESPONSE: Done.
The minimum allowable slope on a gutter is 0.4%. Therefore, the 0.19% slope is not adequate and should
be corrected. Please look at all the possibilities for the cross slopes and the flowline slopes to determine if
the design can comply with the street standards. If any variances are needed to the street standards, contact
me (Mark Callum) at 221.6605.
RESPONSE: This has been corrected.
Please show the curb and gutter around the switch.
RESPONSE: Done.
Please provide all vertical curve information.
Add Note #3: A typical cross section of Mason street is shown on sheet (XX).
RESPONSE: Done.

Dear Mr. Dustin:
Following are our responses to your comments regarding your review of our submittal for the Civic Center
Office Building. Your Comments followed by Response:
1. The inlet on the comer of maple and Howes is called -out to be removed on the Demolition and
Removal Plan, while it needs to remain. Please correct the notation on that sheet.
RESPONSE: This inlet needs to be relocated. It is to be removed as noted on the demolition plan, and will
be reconstructed as shown on the utility plans.
2. The utility duct bank as shown in Howes Street along the north of this site will not fit between the
existing water and the storm lines. It was agreed during earlier meetings between the consultant,
Stormwater, Light and Power and Water and Sewer that the best location is for that duct bank is to go
between the existing storm line and the existing gas line. Please revise the plans accordingly to show
new duct bank location. Please provide a cross-section at the correct scale showing all utilities at
several locations along this duct bank. Please contact Public Service Co. to make sure that the agreed
upon utility duct bank location will work for them as well.
RESPONSE: Done.
3. Please provide a better detail showing how the reconstructed storm sewer manhole will fit behind the
back of curb_ on Mason street. Will the manhole lid location interfere with the pedestrian sidewalk
access ramp?
RESPONSE:. The ramp has been revised such -that there is no conflict between the ramp and the manhole.
4. There seems to be very minimal slopes for flowline along the alley on the west side of the building,
will that impede drainage in that area? Please provide additional flowline elevations and alley cross -
sections in this area.
RESPONSE: While the proposed topography and flowline design has changed, this additional information
is now included on the plans.

Dear Mr. Hill:
Following are our responses to your comments regarding your review of our submittal for the Civic Center
Office Building. Your Comments followed by Response:
COMMENT:
Show meter pit location on landscape plans and provide required landscape/utility separation distances.
RESPONSE: Done.
COMMENT:
Provide a minimum of 5 feet between water service and proposed flagpole on site plan.
RESPONSE: There is not sufficient.distance between the flagpole bases to provide 5 feet between the
water lines and the bases. Providing 5 feet between the fire service and the 2" water service, there is just
less than 4 feet between the water lines and the bases. This is the best we can do short of revising the site
plan.
COMMENT:
Match invert of proposed sanitary sewer service drop connection to crown of existing sanitary sewer main.
RESPONSE: Done.
COMMENT:
According to the plans the proposed fire hydrant lateral will cross under the existing storm sewer at or near
the same location as the proposed duct bank will cross under the storm sewer. How will these crossings be
accomplished? Provide complete details for all water line lowerings.
RESPONSE: The fire hydrant lateral will cross over the storm sewer. The bottom of the utility duct bank
is sufficiently higher to provide clearance for the fire hydrant lateral without a mechanical lowering.
COMMENT:
Correct all plan and profile views to correctly show what is installed in the field.
RESPONSE:
COMMENT:
Provide standard manhole detail for the replacement of the existing manhole in Mason/Maple intersection.
RESPONSE: The existing manhole is not being replaced with this project.

which will adequately screen the utilities (see architectural elevations for location of
utilities mounted on the building)
7. Lot lines are labeled on site plan
8. Dwarf fescue is called out in the landscape notes on the planting plan
9. Parking lot has been reconfigured to reduce the curving of the parking lot; the north

has been changed to two-way. .
Again we would like to thank you all for your help in making this a better project. If you require
