BACKGROUND In October of 2010 the City Council passed Resolution 390-10 authorizing an application for Vision lowa River Enhancement Community Attraction and Tourism (RECAT) grant funding specifically for amenities associated with the Bee Branch Creek Restoration Project. One of the amenities included is to construct a floating island system in conjunction with the construction of the Bee Branch Creek Restoration Project. In April of 2011 the City Council passed Resolution 114-11 approving and authorizing the execution of the RECAT Grant Agreement. The RECAT grant application and grant agreement include funding for a floating island to be constructed as part of the Bee Branch Creek Restoration Project, located within the 16th Street Detention Basin. The proposed floating island system is a form of a wetland which will "bio-mimic" natural floating wetland systems invented by Nature. Vegetated with native plants, it is a beautiful, natural and sustainable eco-system which provides many benefits, from habitat restoration to water cleansing. When a floating island is launched, a whole diverse eco-system is created which attracts life in all its forms, from microbes to nymphs, to butterflies, to fish, birds.... all the way up the food chain. Figure 1 shows the multitude of benefits provided by floating island systems. .a4 s �.u a v fn. w 4 .+ s 6 i ;`'r� �'��.�� 4 i•iar, 1+ �s'Ir��r i sra�r� etr,i i"i�+•'� X1��1 � A .. � i�� "r! �En ��,��Jl�ri�i,"� � �� . - ,�_ ��I;�� ,v�v�;�t3�rlcl��;�ic�u�:�1 . � .

DISCUSSION The Lower Bee Branch Creek Floating Island Project consisted of installing fourteen floating islands that vary in size from 70 square feet to 300 square feet in area. The total combined island area is 2,674 square feet. The islands were assembled, planted with native wetland plants, launched, and anchored to the bottom of the Bee Branch Creek between the 16th Street bridge and the 16th Street Detention Basin. The Lower Bee Branch Creek Floating Island Project was completed by ENCAP, Inc. of DeKalb, Illinois in the final contract amount of$176,045.00, which is 10.67% under the original contract of$197,075.00.
