ARKANSAS RIVER BASIN ABOVE KEYSTONE DAM

103, Arkansas River and Tributaries above John Martin Dam. CO, -
Portland Local Protection Project, CO
STATUS: Project authorized for Phase I stage of dvance Engineering and Design
by the Water Resources Development Act of 1974. This project has been addressed
as part of the Arkansas River and Tributaries above John Martin Dam, CO project.
Phase I studies for the Portland Local Protection project were initiated in FY 83;
no feasible alternative has been formulated.

DESCRIPTION: Phase I GDM studies for Arkansas River and Tributaries above John
Martin Dam, CO, with emphasis on Portland, CO. Survey report dated 24 June 1968
recommended 3,600 feet of intermittent levees and floodwalls along the right bank
of the Arkansas River and 3,250 feet of channel improvements since the survey re...
port was completed, extensive relocations of property have occurred in the flood
plain, reducing project benefits. An economically feasible solution is not
apparent at this time.

104, Arkansas River and Tributaries above John Martin Dam, CO, -
Brewster-Florence Floodway
STATUS: Project authorized for Phase I stage of Advance Engineering and
Design by the Water Resources Development Act of 1974. The project was
addressed as part of the Arkansas River and Tributaries above John Martin Dam,
CO project. Phase I studies for the Brewster-Florence Floodway were combined with
the Florence Local Protection Project. Work on the Phase I GDM was terminated in
FY 82. No economically feasible plan was formulated.

DESCRIPTION: Phase I GDM studies were prepared for Arkansas River and Tribu-
taries above John Martin Dam, CO, with emphasis on Florence, CO. Survey report
dated 24 June 1968 recommended improvements on the Arkansas River from Brewster
to Florence. The improvements consisted of a south bank levee about 31,280 feet

long beginning about 3.5 miles above Florence, CO, and terminating 2.5 miles
downstream at the mouth of the Cocklebur Creek. The levee was designed to
provide laO-year protection. No structural nor nonstructural measures investigated
were economically justified.
