COMMENT
This document provides the Federal Emergency Management Agency’s (FEMA’s) comment regarding a request for a CLOMR for the project described above.
This document is not a final determination; it only provides our comment on the proposed project in relation to the flood hazard information shown on the effective
National Flood Insurance Program (NFIP) map. We reviewed the submitted data and the data used to prepare the effective flood hazard information for your
community and determined that the proposed project meets the minimum floodplain management criteria of the NFIP. Your community is responsible for
approving all floodplain development and for ensuring that all permits required by Federal or State/Commonwealth law have been received. State/Commonwealth,
county, and community officials, based on their knowledge of local conditions and in the interest of safety, may set higher standards for construction in the Special
Flood Hazard Area (SFHA), the area subject to inundation by the base flood. If the State/Commonwealth, county, or community has adopted more restrictive or
comprehensive floodplain management criteria, these criteria take precedence over the minimum NFIP criteria.
This comment is based on the flood data presently available. If you have any questions about this document, please contact the FEMA Map Information eXchange (FMIX) toll
free at 1-877-336-2627 (1-877-FEMA MAP) or by letter addressed to the LOMC Clearinghouse, 847 South Pickett Street, Alexandria, VA 22304. Additional Information about
the NFIP is available on the FEMA website at http://www.fema.gov/nfip.

BFE Change (feet)
Increases due to the proposed project that exceed those permitted under Paragraphs (c)(10) or (d)(3) of Section 60.3 of the NFIP regulations must adhere
to Section 65.12 of the NFIP regulations. With this request, your community has complied with all requirements of Paragraph 65.12(a) of the NFIP
regulations. Compliance with Paragraph 65.12(b) also is necessary before FEMA can issue a Letter of Map Revision when a community proposes to
permit encroachments into the effective floodplain/regulatory floodway that will cause BFE increases in excess of those permitted under Paragraph
60.3(d)(3).
NFIP regulations Subparagraph 60.3(b)(7) requires communities to ensure that the flood-carrying capacity within the altered or relocated portion of any
watercourse is maintained. This provision is incorporated into your community’s existing floodplain management ordinances; therefore, responsibility for
maintenance of the altered or relocated watercourse, including any related appurtenances such as bridges, culverts, and other drainage structures, rests with
your community. We may request that your community submit a description and schedule of maintenance activities necessary to ensure this requirement.
To determine the changes in flood hazards that will be caused by the proposed project, we compared the hydraulic modeling reflecting the proposed
project (referred to as the proposed conditions model) to the hydraulic modeling used to prepare the Flood Insurance Study (FIS) (referred to as the
effective model). If the effective model does not provide enough detail to evaluate the effects of the proposed project, an existing conditions model must
be developed to provide this detail. This existing conditions model is then compared to the effective model and the proposed conditions model to
differentiate the increases or decreases in flood hazards caused by more detailed modeling from the increases or decreases in flood hazards that will be
caused by the proposed project.
The table below shows the changes in the BFEs:

DATA REQUIRED FOR FOLLOW-UP LOMR
Upon completion of the project, your community must submit the data listed below and request that we make a final determination on
revising the effective FIRM and FIS report. If the project is built as proposed and the data below are received, a revision to the FIRM and
FIS report would be warranted.
• Form 1, entitled “Overview & Concurrence Form.” Detailed application and certification forms must be used for requesting final
revisions to the maps. Therefore, when the map revision request for the area covered by this letter is submitted, Form 1 must be included.
If as-built conditions differ from the proposed plans, please submit new forms, which may be accessed at
http://www.fema.gov/plan/prevent/fhm/dl_mt-2.shtm, or annotated copies of the previously submitted forms showing the revised
information.
• Hydraulic analyses, for as-built conditions, of the base flood; the 10-percent, 2-percent, and 0.2 percent annual chance floods; and the
regulatory floodway, together with a topographic work map showing the revised floodplain and floodway boundaries. Please ensure that
the revised information ties in with the current effective information at the downstream and upstream ends of the revised reach.
• An annotated copy of the FIRM, at the scale of the effective FIRM, that shows the revised floodplain and floodway boundary delineations
shown on the submitted work map and how they tie into the floodplain and floodway boundary delineations shown on the current effective
FIRM at the downstream and upstream ends of the revised reach
• As-built plans, certified by a registered professional engineer, of all proposed project elements

• A copy of the public notice distributed by your community, stating its intent to revise the regulatory floodway, or a signed statement by
your community that it has notified all affected property owners and affected adjacent jurisdictions
• Documentation of the notification to property owners who will be affected by any widening/shifting of the base floodplain and/or any
BFE increases along Cache La Poudre River.
• Evidence that your community has, prior to approval of the proposed encroachment, adopted floodplain management ordinances that
incorporate the increased BFEs and revised floodway boundary delineations to reflect the post-project conditions, as stated in Paragraph
65.12(b)
• A letter stating that your community will adopt and enforce the modified regulatory floodway, OR, if the State/Commonwealth has
jurisdiction over either the regulatory floodway or its adoption by your community, a copy of your community’s letter to the appropriate
State/Commonwealth agency notifying it of the modification to the regulatory floodway and a copy of the letter from that agency stating its
approval of the modification
• FEMA’s fee schedule for reviewing and processing requests for conditional and final modifications to published flood information and
maps may be accessed at http://www.fema.gov/plan/prevent/fhm/frm_fees.shtm. The fee at the time of the map revision submittal must be
received before we can begin processing the request. Payment of this fee can be made through a check or money order, made payable in
U.S. funds to the National Flood Insurance Program, or by credit card (Visa or MasterCard only). Please forward the payment, along with
the revision application, to the following address:
LOMC Clearinghouse
847 South Pickett Street
Alexandria, VA 22304
After receiving appropriate documentation to show that the project has been completed, FEMA will initiate a revision to the FIRM and FIS
report. Because the flood hazard information (i.e., base flood elevations, base flood depths, SFHAs, zone designations, and/or regulatory
floodways) will change as a result of the project, a 90-day appeal period will be initiated for the revision, during which community officials
and interested persons may appeal the revised flood hazard information based on scientific or technical data.
