ALTERNATI E NO. 1

Beneficia Effects

Shor -term benefits of this proposal are limited and relatively minor.
Some positive benefit to the economy may be realized through construction
cont acts for the proposed channelization and improved conduit. Implementa-
tion co.sts of this alternative are the lowest of those prl:lposed in the
Inte im Report. .

This alternative stresses long-term benefit through the utilization of the
floo plain zone. The Interim Report states: "This would lead to minimizing
pote tial flood damage, if not total elimination, over a period of time."
Deli eation of flood plain zone to this,area would qualify the property
owne s for federally subsidized flood insurance.

Adverse E fects

Cons ruction of the proposed channel and conduit will generate noise levels
that would be moderately adverse for a short term.

Whil the flood plain zone would provide a long-term beneficial effect for
the ommunity at large, property owners within the flood plain zone would not
be a le to repair or replace severely damaged or destroyed structures. This
woul have a further effect of adversely affecting property values within the
zone district.

This alternative would only alleviate potential flood damage

ALTERNATI E NO.2

Beneficia Effects

Cons ruction requirements of this alternative would have moderate short-
term effects on the local economy.

This alternative has many long-term benefits~ Major channel and drainage
impr vements are proposed that would eliminate potential flood danger on
the ain tributary, west of Datura, and along all of the south tributary
from Datura to the confluence.

Anot r major benefit to the area would:be the detention pond, located just
east f the railroad tracks, which could be the focal point for a neighbor-
hood park. The proposed channel would provide a setting for a trail system
that ould run between Datura and Prince Streets. This would be an
exce lent educational opportunity for the adjacent elementary school, and
woul also provide eventual connection to other trail systems and the
Sout Platte Valley Park.
