Item Summary
Consideration of a floodplain development application to complete improvements in Horn Creek
to establish a natural channel and improve flows in the creek by eliminating a culvert at risk of
failure. The improvements are within the Special Flood Hazard Area (SFHA) and regulatory
floodway for Horn Creek. Applicant: City of Central Point; Agent: RH2 Engineering

Background
There are seven (7) streams that flow through the City of Central Point. Horn Creek is a small
tributary to Jackson Creek located in the southwestern portion of the City. There is a 100-ft
section of Horn Creek that flows through a private culvert (Attachment "A"). The City recently
learned that the culvert is at risk of failure and will increase flood risk to surrounding property
owners. At this time, the City is helping explore options to address this recently identified flood
risk. One potential solution is to plug the culvert and establish a channel connection via an
existing bypass channel immediately west of the culvert. To accomplish this, work will need to
be done within a regulatory floodway and floodplain for Horn Creek.
As a participating community in the National Flood Insurance Program (NFIP), the City requires
that floodplain development activities be evaluated and permitted to minimize flood damages,
promote safety and protect environmental resources. In accordance with CPMC 8.24.090, the
Floodplain Development permit is subject to Type III (quasi-judicial) procedures set forth in
CPMC 17.05.400. In rendering a decision on the application, the Planning Commission must
consider the criteria in CPMC 8.24.200 relative to floodway development. At the June 7, 2022
meeting, staff will provide a presentation on the application and its conformance with the
applicable criteria needed to restore the stream channel conditions.
Protect Desert tion:
The project is within the SFHA and regulatory floodway of Horn Creek and proposes to establish
a natural creek channel in an existing bypass channel within the banks of the creek and
abandon the existing culvert. The culvert will remain in place, but will be plugged on both ends
to prevent flows from entering. Work within the channel includes widening the areas at the north
and south ends of the culvert to establish a riparian bench, preventing standing water in low flow
conditions and sizing the channel to provide capacity in high flow scenarios.
330
In accordance with CPMC 8.24.200(A), a No -Rise certification is required to evaluate the
existing flood conditions before a project and the proposed flood conditions following the
completion of the project. According to the No -Rise documentation, the elimination of the culvert
and establishing a natural channel within Horn Creek improves flows within the channel
resulting in a decrease in flood elevations and provides fish passage through the project area,
where the culvert and a diversion weir currently prevent passage (Attachment "B"). Since
construction of the project does not result in an increase to flood elevations, the documentation
is consistent with the City's no -rise standard.
Issues
There are no issues related to this application.
Findings of Fact & Conclusions of Law
The proposed floodplain development within Horn Creek has been evaluated against the
applicable Flood Damage Prevention Criteria set forth in CPMC 8.24 and found to comply
as evidenced in the Applicant's No -Rise documentation (Attachment "B") and the Planning
Department's Supplemental Findings (Attachment "C").
Conditions of Approval
No conditions of approval are recommended.
