Comment #1: Will the parking be adequate? The body shop alone could have 46 vehicle
spaces for customers/staff (not including display/storage of inventory). Recent
violation of storing inventory off the site prompts this question.
The site is utilized for maximum efficiency of parking for the intended use
- we are not aware of any violations!
Comment #2: Will trash/rubbish be stored within the building? No trash enclosures shown.
Please refer to General Note 43.
Comment #3: Detached building, will that be built now? No elevations shown. If built later,
minor amendment required for footprint and elevations at that time.
Please refer to General Note #6.
I believe we have addressed all concerns known to us.

Comment # 26: Offsite Detention Pond Modifications:
Please provide a letter of recognition from the property owners to the north that
the ponds on their site will be modified. Also, please provide documentation
that the new 100 year water surface elevations will be within the current
drainage easements. This can be done with an exhibit in the report showing the
existing WSEL, new WSEL and current drainage easements.
A telephone conversation with Wes Lamarque of the City of Fort Collins
Stormwater Department on August 16, 2001 confirmed that the ponding
being proposed with the Pedersen Auto Plaza Expansion lies within
existing drainage easements and/or extents of ponding 'as dictated by
construction drawings designed by Stewart & Associates, and approved
by the City of Fort Collins. Furthermore, the addition of the horizontal
orifice plates will be done in such as manner so that no temporary
construction easements will be needed. He also verified that permission
was not required from the off -site property owners due to the precedence
of ponding already being approved for those properties. He did suggest
that a letter be written to the affected property owners as a courtesy to
remind them of the existing drainage easements and/or approved extents
of ponding, and to inform of the activities that will take place with the
Pedersen Auto Plaza Expansion. A copy of these letters will also be
provided to the City, but neither written permission nor approval is
required from the off -site property owners. An exhibit has been provided
to easily show that the ponding being proposed with this project is
consistent with what has already been approved and/or recorded.
Comment # 27: Please look into the possibility of adding the WQCV to the quantity detention.
Please see redline comment on page 4 of report.
The release rate and storage volume of Detention Pond A have been
modified slightly so that the pond provides the required detention storage
volume on top of the required water quality capture volume. This has
been done to accommodate the event where a 100-year storm closely
follows a storm that has already filled the water quality capture volume.
In order to achieve this, the 1-foot minimum freeboard requirement needs
to be violated, and the City will need to grant a variance to this
requirement.
Comment # 28: Please see additional redline comments in the plans and report.
See redline plans for additional responses to comments. (written in green)

LOCKWOOD ARCHITECTS, 217 Jefferson, Fort Collins, Colorado 80524. phone: 970.493.1023 fax: 970,493.6765
The release rates for Detention Pond A have been revised to be consistent
throughout the drainage report and construction drawings. In addition,
the emergency overflow path for Detention Pond A is now labeled on the
Drainage Plan.
Comment #22: In Basin P-mod, the spillway is designed to carry the 100 year flow to the
detention pond, while the storm sewer is designed to carry the 10 year flow.
This is acceptable, however it is required to have the swale carry the 100 year
flow times 1. 33for freeboard. The overtopping elevation is around 49.8 just
northwest of the proposed building. Please show that the 100 year flow X 1.33
can pass without flooding the new proposed building, which has a F.F.
elevation of 40.50. This should be just a matter of documentation in the report.
The calculations for Weir Section B have been revised in the drainage
report to 'show that the 100-year flow x 1.33 will safely pass without
flooding the proposed finished floor.
Comment # 23: Water Quality Outlet Structure:
Please use City of Fort Collins standard outlet structure rather than drilling
the orifice holes through the concrete. See USDCM, Vol. 3, Typical Structural
BMP Details section, Figure 6-a.
The structure has been designed in accordance with the Urban Storm
Drainage Criteria Manual, Volume 3 — Best Management Practices
updated in September of 1999. The proposed structure has been
customized to be built into the walls of Detention Pond A. Details have
been added to the construction drawings for the well -screen trash rack,
which is consistent with what the City uses. The proposed water quality
structure will operate like the one in Figure 6-a of the USDCM; however,
it has been adjusted to be flush with the detention pond retaining walls.
Comment # 25: Please consider tailwater affects for the existing storm sewer in Mason Street.
There will definitely be some tailwater depth and even though there is no
current documentation, a simple analysis can be done with the flow rates known
for the ponds upstream draining into the pipe, and the flow to the retrofited
inlet.
An analysis was done at the modified inlet on the west side of Mason
Street. This inlet has an existing 17.5" RCP coming out of it that conveys
flow under Mason Street. The head required to convey the flows from
proposed Storm Sewer Line C combined with the surface flows from
Mason Street through the existing pipe was calculated. This elevation was
then used as the starting point for the storm sewer modeling. As a result,
the hydraulic grade lines of both Storm Sewer Line B and Line C have
been raised.

Comment # 1 S: Label the 7 foot high fence on the utility plans.
The proposed 7' high fence is now noted on the plans.
Comment # 16: What does the detention pond handrail sit on? Are there to be poured
columns? The notes on the plans indicate that the retaining wall does not
extend across this area and I assume it will not be bolted down to the dirt.
Need more info here.
The steel handrail will be secured to the top of the concrete retaining wall,
via anchor bolts. See Grading Plan for clarification.
Comment # 17: It appears that off -site drainage and construction easements will be needed
with this project.
A telephone conversation with Wes Lamarque of the City of Fort Collins
Stormwater Department on August 16, 2001 confirmed that the ponding
being proposed with the Pedersen Auto Plaza Expansion lies within
existing drainage easements and/or extents of ponding as dictated by
construction drawings designed by Stewart & Associates, and approved

orifice plates will be done in such as manner so that no temporary
construction easements will be needed.
Comment # 18: Make changes to the ped ramp detail as shown.
See revised details for changes to pedestrian ramp.
Comment # 19: Provide detail 7-20A and 22-1.
Details 7-20A and 22-1 are now included in the plan set.

Note #2 on the plat. Doesn't make sense as written. I am guessing that the
intent of this note is that the easements shown on the prior plats should be
vacated. Here is an example of a note on another plat that has been filed.
THE EASEMENTS SHOWNONL0T 2 OF HIGHLAND A UTOS P. U.D. AND
LOT 1 PEDERSEN A UTO PLAZA SUBDIVISION ARE TO BE VACATED
WITH THIS PLAT AND REPLACED WITH EASEMENTS AS SHOWN
HEREON.

distance easement on this plat.
The sight distance easement note has been removed from the plat.
Comment # 9: Label the street width and easement widths.
The street width and easement widths now appear on the plat.
Comment # 10: Make changes as shown or add information as needed to the general notes.
The changes and additional information are reflected in the plat.
Comment # 11: Indicate that the plat is to be included in this set after the cover sheet.
The plat is now included in the overall utility plan set, as requested.
Comment # 12: Do not indicate that work is to be done by others. The developer is responsible
for all work shown on these plans. You can have agreements with someone else
to do the work, but everything shown on the plans will need to be done with this
project.
The note, `By Others" has been removed from the utility plan.
Comment # 13: Missing some sidewalks and crosswalks on the utility plans that are shown on
the site plan.
The engineering drawings have been updated to include the additional
sidewalk and crosswalks, as requested.
Comment # 14: Need to indicate that the street patch is to be in accordance with City standards
with exact limits to be determined by the City inspector.
The limits of the street patch have been revised, in addition to adding the
note requested.

to redline comments by Wes Lamarque of the City's Stormwater
Department that appear in the drainage report, the City has accepted the
variance that Detention Pond A does not have a full one -foot of freeboard.
Comment # 40: Stormwater has indicated that the proposed water quality outlet structure is not
consistent with what the City uses.
The proposed water quality structure is indeed consistent with the
structures currently being used by the City of Fort Collins. The structure
has been designed in accordance with the Urban Storm Drainage Criteria
Manual, Volume 3 — Best Management Practices updated in September of
1999. The proposed structure has been customized to be built into the
walls of Detention Pond A. Details have been added to the construction
drawings for the well -screen trash rack, which is consistent with what the
City uses.
Comment # 41: Stormwater has indicated that letters of intent from the affected property
owners for the necessary of -site improvements must be provided to the City.
A telephone conversation with Wes Lamarque of the City of Fort Collins
Stormwater Department on August 16, 2001 confirmed that permission
was not required from the off -site property owners due to the precedence
of ponding already being approved for those properties. He did suggest
that a letter be written to the affected property owners as a courtesy to
remind them of the existing drainage easements and/or approved extents
of ponding, and to inform of the activities that will take place with the
Pedersen Auto Plaza Expansion. A copy of these letters will also be
provided to the City, but neither written permission nor approval is
required from the off -site property owners.
Comment # 42: Will the expansion of this facility generate new employees?
Yes - It is estimated that between 10 to 16 new jobs would be created.
Comment # 43: The landscaping to be used for screening of parking and vehicle display areas
along Mason Street is either too short (less than 30') or does not extend far
enough to provide 70% screening (see the. red -lined Landscape Plan).
Additional plant material has been placed for proper screening. The plant
material proposed is consistent with the existing Landscape concept to the
south.
Comment # 44: Please contact the City's Transportation Planning Department to discuss the
timing for construction of the previously approved trail access from Mason

Just one lot. (see label on plat)
Comment # 34: Engineering does not really want the textured and painted pedestrian crossing
in the Mason Street right-of-way. However, Transportation Planning would
like this to remain to match the existing crosswalk on the original site.
It is intended for the proposed new crossing to match the existing crossing
to the south. City Staff needs to resolve their own conflict and advise us
accordingly.
Comment # 35: The retaining walls for the detention pond should be shown on the Site and
Landscape Plans.
Done
Comment # 36: Engineering has asked why there is a steel retaining handrail?
The retaining wall in this area is greater than 30" in height.
Comment # 37.• Engineeringhas indicated that the building envelope extends into an easement.
This is not permitted.
The proposed 10' utility easement has been notched to accommodate the
building, as previously agreed to by Jeff Hill, per coordination with him,
prior to previous submittal.
Comment # 38: Off -site drainage and construction easements are needed. They must be
provided, reviewed, and accepted by the Cityprior to scheduling this item for
public hearing.
A telephone conversation with Wes Lamarque of the City of Fort Collins
Stormwater Department on August 16, 2001 confirmed that the ponding
being proposed with the Pedersen Auto Plaza Expansion lies within
existing drainage easements and/or extents of ponding as dictated by
construction drawings designed by Stewart & Associates, and approved
by the City of Fort Collins. Furthermore, the addition of the horizontal
orifice plates will be done in such as manner so that no temporary
construction easements will be needed.
Comment # 39: Stormwater has indicated that the detention pond needs freeboard.
A variance is being requested for the City's detention pond freeboard
requirement. This variance request appears in the written text of the
drainage report. The variance is needed in order to provide the entire
detention volume on top of the water quality capture volume. According
