the respective basin in Town of Timnath Master Drainage Plan, and then the detention volume and release rates
were prorated from this percentage. The volume was then compared to the Urban Drainage Detention Basin
Volume Estimating Workbook, Version 2.33. The more constrictive volume is shown on the ODP Drainage Plan.
These detention volumes will be adjusted as the site further develops and proposed percent impervious are
further refined with Project Development Plan submittals.
The development will provide multiple onsite detention ponds. The multiple detention ponds will reduce the
need of a single, large regional detention pond, provide additional water quality treatment through a treatment
train, and enhanced landscaping per the City of Fort Collins Stormwater Criteria Manual. Water quality and LID
requirements will be provided with each respective Project Development Plan per the City of Fort Collins
Stormwater Criteria Manual.
Detention pond release rates and volumes will be determined per the Town of Timnath Master Drainage Plan. All
other stormwater requirements will be per the City of Fort Collins Stormwater Criteria Manual.
Floodplain:
The far northwest corner of the site is located within the existing Boxelder Creek Flood fringe and floodway. FEMA
FIRM Panel Number 08069C0984H and 08069C1003G for Larimer County, Dated May 2, 2012 is referenced in this
study. Base (100-year) flood elevations in the vicinity of the proposed project range from 4919.9 to 4920.7
(elevations referenced to the City of Fort Collins NAVD 88). Please see th e attached FIRMette and City Floodplain
Mapping exhibits.
A CLOMR has been submitted to FEMA and was approved for the Boxelder 6 CLOMR prepared for Boxelder Basin
Regional Stormwater Authority (Case Number 15-08-0329R). Improvements include an overflow channels, box
culverts, dams, and bridge replacement. These improvements are proposed to remove much of this property
from the flood fringe and floodway. Limits for both the existing FEMA Floodway/Floodplain and the proposed
Floodplain/Floodway are shown on the Master Drainage Plan. These master plans were prepar ed utilizing the
proposed floodplain/floodway. Most of the development will avoid the proposed floodplain/floodway limits per
the Boxelder 6 CLOMR revisions.
It is acknowledged that any improvements located within the Boxelder Creek floodplain and floodway must
satisfy the standards of Chapter 10 of City Code; and final design documents will be completed accordingly. Any
development within the Boxelder Creek floodplain will be required to provide a City of Fort Collins floodplain use
permit prior to construction. Any development with the Boxelder Creek floodway will be required to provide a
City of Fort Collins no-rise certification prior to construction.
Offsite Flows:
Offsite flows, except those identified as part of the Boxelder Creek floodplain and floodway, are not expected to
impact this site. However, further analysis will be required during Project Development Plan to ensure there are
no offsite stormwater impacts from Fox Grove, Kitchell Subdivision, and Poudre School District Middle/High
School developments. Offsite flows will be passed through the site without providing any detrimental impact to
the development and downstream users.
In summary, this Overall Drainage Report letter adequately addresses any potential stormwater changes
associated with the proposed Overall Development Plan Amendment. In general, there are no significant changes
proposed at a major drainage level. The ODP complies with the governing City of Fort Collins Master Drainage
Plans, and the previously approved drainage plans specific for the subject property
