1, Describe the problem in detail: WIlen local raiDs of 1.5 iDehes or more occur in the watershed above the
project area, the existing drainage system can not carry the water away iD a timely maDDer, thereby
causing floodiDg aDd damage to area properties aDd the roads.

2, Describe flow often this problem occurs: The area will be flooded ODe or two times a year during a
Dormal year.

3. Does the proposed project merely identity or analyze the hazards or the problem(s)? No, this will reduce
the frequeacy of the flooding.

.4. When will the project as a whole (include all pbases/parts) be completed? December 31, 200z

5. Describe in detail flow the project reduces hazard effects and risks: By iDcreasing the eapacity of the
drainage system, the water will flow past the presently floodiDg areas, thereby reduclag the risk of
flood damage. It wiD also reduce the flooding of laigbways, which may end up saviDg humaa lives.

E. Describe how the project reduces hazard effects and risks. This project will iDcrease the capacity of
the storm water draiaage system; tlaereby anow the floodwater to flow oat of the preseatly
f100diDg areas aDd thea releasiDg It OD a cODtrol1ed basis. This win greatly reduce the frequeney of
f100diag these areas. The project will reduce the flooding elevation by at least 8 iDches during a
five-year storm event.
