Twin Creeks CLOMR Review
Scope of Work
Northwest Hydraulic Consultants, Inc. (NHC) has been asked by the City of Central Point
(City) to provide the following scope of work and cost estimate to conduct an independent
technical review of a Conditional Letter of Map Revision (CLOMR) submittal package. The
CLOMR submittal package was prepared by Public Works Management, Inc. (PWM) to
document proposed changes to the effective FEMA 100-year floodplain and regulatory
floodway within the Twin Creeks Development. Future development of the site requires that
a CLOMR submittal be accepted by FEMA.
NHC will complete the following tasks as part of the independent technical review.
Technical Review
NHC will perform a cursory review of the hydraulic modeling analysis, revised floodplain
mapping, and documentation from the PWM CLOMR submittal package, as provided by the
City. Review of the hydraulic model will include evaluation of specified boundary conditions,
backwater profile computations, and encroachment analysis. Mapping will be reviewed to
assess consistency with hydraulic modeling, as well as merging with effective FEMA
mappirig.
Memorandum
NHC will prepare a brief memorandum that summarizes the findings of the technical review,
identify any existing inadequacies found in the existing CLOMR submittal package, and if
needed, provide suggestions for improving the data submittal.
Schedule
To be mutually agreed upon by the City and NHC.
