RE:Mulberry Connection PDP190015
Dear Ms. Bilobran:
Thank you for the comments on the above-mentioned project. In an effort to address your
comments concisely and simplify your review of the I-25 Frontage Road Plans, we have
summarized the CDOT comments and our responses below.
COMMENT RESPONSE LETTER
COMMENTS CONTAINED WITHIN 3/10/2021 EMAIL
R4 Stormwater:
1. Please see attached filled out deeds. One last requirement from the CDOT side. I need
to get a copy of the title commitment for the property prior to their filling out the names
on the deed. We were able to trace title back to 1975. All transfers were via warranty
deed. If they don't have a title commitment for the plat work they are doing, I think we
are ok with the research I have done.
The deed to CDOT needs to show the Grantor's name as:
Poudre Valley Co-Operative Association, Inc., a Colorado Corporation
Response: Acknowledged. Developer continues to coordinate dedication instruments with
City and CDOT. Developer to submit the requested forms via separate email.
R4 Hydraulics:
2. The City of Fort Collins pointed out a potential discontinuity between the
documentation provided in the Drainage Report (dated Dec 2, 2020) and the Frontage
Road Plans (dated Dec 2, 2020). The drainage report seems to indicate the work
stopping at Redman Drive based on the Existing and Proposed basin delineations and
grading. However, the Plan set appears to be indicating additional modifications to the
Frontage Road pavement, roadside drainage, and cross-culverts which do not appear
to be addressed in the Drainage Report
We concur with the City's assessment that the area south of Redman should have
Page 2
kimley-horn.com 4582 South Ulster Street, Suite 1500, Denver, CO 80237 303 228 2300
been included in the drainage report and brought to CDOT's attention as a referral
reviewer. We recommend that these additional improvements be addressed and
documented in an addendum to the report that was initially submitted to CDOT for
review, or that the work south of Redman be deleted from the work and excluded from
the Access permit. Please provide the modified report for our re-review, focusing
specifically on any changes to the capacity of the roadside drainage and potential
covering up of some cross-culverts which was not readily apparent in the initial report.
Response: Correct, improvements to the Frontage Road south of Redman Drive are
proposed. Revised Drainage Report included for CDOT review.

ROW update:
1. What the City wants seems to be 6 of 1, half dozen of another. We don't want to make
a mountain out of a molehill though, so we'll be flexible. We will take the direct title
from the dedication. R4 will add language that it is from a development property.
Currently we are going to review the legal and then we will add the required language
to the deed that the property will be transferred to CDOT for $1.
Response: Acknowledged. Developer continues to coordinate dedication instruments with
City and CDOT.
I-25 Design Residency:
1. Approved plans
Response: Acknowledged.
R4 Operations Engineer Comments:
1. Submittal 9 Frontage Road Plans:
· use the updated S-627-1 6" standards.
· ONLY stencil is needed in sheet 10/15
· Stop bar needs to be 2' wide. They don't have a width specified
Response: Acknowledged. Plans updated to incorporate CDOT comments.
Submittal 6 Comments:
1. Who will be maintaining the streetlights they are proposing along the frontage road?
Are these needed?
Response: Note added to sheet C4-0. City of Fort Collins will install and maintain streetlights.
Streetlights required per City standards.
2. Streetlights should be using breakaway bases per standard attached. P 13/13 does
not reflect this
Response: Streetlights will be installed and maintained by the City of Fort Collins. The City
will coordinate directly with CDOT regarding the correct streetlight pole and base.

3. Are there sign plans? I see mentions of relocated street signs (ie sub 9 sheet 11) but
not signs being called out.
Response: Refer to Sheet C5-0 and C5-1 for our Signing and Striping Plans. All signed
identified on the Removal and Reset Plans have a corresponding callout location on the
Signing and Striping Plans.
4. With regards to the FoCo comments- Let's ensure the S-627-1 6" standards are being
used. The FoCo comments seem to be a different striping layout.
Response: Acknowledged. CDOT standards are being utilized.

Traffic Design & Safety / ADA residency Comments
1. Gen Note 1 - Since this is a CDOT facility, our specs should take precedence. At some
point this may be a City local road thru devolution but that time is not Today.
Response: Acknowledged.
2. Gen Note 26: NPDES being specified as the governing agency on erosion control.
This is not a federally owned frontage road so it should be CDPHE instead.
Response: Acknowledged, note updated to reflect change to CDPHE.
3. Gen Note 29: This note seems to relieve the City from testing. CDOT reserves the
right during construction by our own Region 4 materials lab perform pop-quiz style
popup testing without warning to verify that the contractor's results are accurate. There
isn't really a change per say to the notes except for this statement of our intent. If the
City isn't performing testing oversight CDOT may elect to.
Response: Acknowledged, note updated to clear up confusion.
4. Sheet 3 needs to be updated with the most recent standard plans list I think 12/30/20
is the most recent.
Response: Acknowledged, standard plans updated.
5. Sheet 4: I recommend they show the 6" of subgrade prep depth below the sidewalk
Response: Acknowledged, pavement inset detail updated to include 12” subgrade preparation
depth per Geotech recommendation.

General Comments:
1.Hydraulics approved your report so that discipline is done.
Response: Acknowledged.
2. Environmental additional comments are in the attached doc:
1. Migratory Bird Treaty Act (MBTA):
Page 4
kimley-horn.com 4582 South Ulster Street, Suite 1500, Denver, CO 80237 303 228 2300
It has been determined that the proposed project could potentially result in the take
of migratory birds, their nests, and or their eggs. It is the applicant’s responsibility
to follow the MBTA federal regulations.
Comments: MBTA was mentioned in the Ecological Characterization Study in
regards to seasonal restrictions. These restrictions need to be followed within
CDOT ROW.
Response: Acknowledged. Project shall comply with all Federal regulations.
2. Historic Properties (Archaeology, History):
It has been determined that archaeological and/or historical resources may be
affected by the proposed project activities. It is the applicant’s responsibility to
comply with regulations under the Colorado Office of Archaeology and Historic
Preservation. If archaeological resources are discovered within CDOT ROW, the
applicant must contact CDOT’s Staff Archaeologist.
Comments: If the irrigation ditch is within CDOT ROW and will be impacted by the
project, the applicant will need to contact the State Historic Preservation Officer.
Response: Existing irrigation ditch is not within CDOT ROW.
3. SWMP and Colorado Discharge Permit System:
CDOT requires a Storm Water Management Plan (SWMP) be prepared for every
project occurring within any existing or newly dedicated public right-of-way.
Therefore, before a permit can be issued, the applicant must provide a copy of the
SWMP to the CDOT Region Environmental Unit. Additionally, if the project results
in one acre or more of earth disturbance, the applicant must obtain a Colorado
Discharge Permit issued by the Colorado Department of Public Health and
Environment. It will be the applicant’s responsibility to ensure all conditions of the
permit are adhered to during and after construction.
Projects within a Municipal Separate Storm Sewer System (MS4) area that result
in disturbance of one acre or more; or have under one acre of disturbance, but are
part of a larger common plan of development or sale; must provide the SWMP to
CDOT Region Environmental Unit for review and approval and should obtain a
Memorandum from the local MS4 municipality that they will perform MS4-required
stormwater permit compliance audits.
Response: Acknowledged. Developer shall obtain CDPHE General Permit prior to any earth
disturbing activities. Email confirmation from the City of Fort Collins provided to CDOT on
1/25/21 regarding SWMP compliance/inspections.

General Comments:
1. For the ROW deed front, Region 4 is in the process right now of modifying the required
deeds we want the developers to provide. That is the holdup in my response. I have
Page 5
kimley-horn.com 4582 South Ulster Street, Suite 1500, Denver, CO 80237 303 228 2300
your plans into Region 4 Right-of-Way with the question of “Just tell me what kind of
deed they want”.
Response: Acknowledged. Developer continues to coordinate dedication instruments with
City and CDOT.
2. For the SWMP Fort Collins e-mail, I had to wait a bit for R4 SWMP to approve it since
they originally wanted a memo. The verbiage is the same though really so ultimately,
I got them to accept the e-mail. They didn't comment on the acreage you provided
which I assume means "That was the information they needed and are good" but
again.... I followed up with them to avoid any last minute surprises.
Response: Acknowledged.
3. I am still waiting on the following comments back. I reached out to the appropriate
CDOT person pressing them for their comments as quickly as possible right before
sending this e-mail: Signing & Striping, Traffic Design & Multimodal, Hydraulics, and
the I-25 Residency.
Response: Acknowledged.
4. I did receive R4 Materials comments back, which are:
I have reviewed their designs and report and they are marked Revise and Resubmit
as they are utilizing a version of Pavement ME that CDOT does not currently accept.
They are required to rerun their design using CDOTs accepted version of Pavement
ME which is version 2.3.1 Hotfixed and specifically are required to use CDOT's
calibration coefficients and specific HMA materials loaded from CDOT's database. We
do not allow use of Default materials for design. Also, they are required to use CDOT's
weather data which they can also obtain through Melody below.
They can contact Melody Perkins for the appropriate information
at melody.perkins@state.co.us
Response: Acknowledged. Pavement Design Report updated. Refer to revised report
included with resubmittal.

General Comments:
1. Thank you for the stormwater quantity information. I've passed that on to R4
environmental for them to continue their review. Please do not forget the comment on
"We will need a memo from the appropriate municipality that they will audit for MS4
compliance". It is up to you all to liaise with the appropriate local stormwater
department. Pursuing & obtaining that memo is not something CDOT undertakes on
your behalf. It is your responsibility.
Response: Per response above, email confirmation from the City of Fort Collins provided to
CDOT on 1/25/21 regarding SWMP compliance/inspections.
2. Our Roadway design unit sent in the following comments to address in the next round
of plans you provide:
Page 6
kimley-horn.com 4582 South Ulster Street, Suite 1500, Denver, CO 80237 303 228 2300
Roadway Comments:
1. At Redman Dr...doesn't appear thru lanes, NB and SB I-25 Frontage Rd lanes, are
lining up.
Response: Plans updated to better align thru lanes. Refer to sheets C5-0 and C5-1.
2. For 45 MPH Speed Limit...Taper Rate = 13.5:1 (Minimum) and Redirect Rate 45:1
(Minimum). Seems like we are violating the Redirect Rate on both the North and
South side.
Response: Tapers have been updated to reflect the minimums. Refer to sheets C5-0
and C5-1.
3. 12 FT Lane width for new SB I-25 Frontage Rd lane
Response: Lane width updated to 12’. Refer to sheets C2-0, C2-1, C5-0 and C5-1.
4. 16 FT Median width (4 FT Median | 12 FT LT Turn Lane) desirable...provide
justification for using 12 FT minimum width with no Median.
Response: Ultimate street cross section determined by City of Fort Collins based on an
anticipated devolution, but pavement markings located based on CDOT criteria. Median
width reduced to accommodate full shoulder widths.
General Comments (cont.):
3. It's ironic slightly that you're writing about the "Other mechanism" for ROW dedication.
Up until literally a week ago I would have said "We will take a Quit Claim Deed from
you". A week ago the Region 4 Right-of-Way manager changed the process to "We
will take a warranty deed".... but then wanted to continue discussing the issue with his
staff. As of right now I can't tell you whether we want a Quit Claim Deed or a Warranty
deed. Whichever way we pick I will provide a with an example. Please follow up with
me in a week to see if the issue is settled internally here.
Response: Acknowledged. Developer continues to coordinate dedication instruments with
City and CDOT.
We appreciate your review and approval of these final plans. Please contact me at (303) 228-2318 or
dan.skeehan@kimley-horn.com should you have any questions.
