HAZARD MI'TIGATION GRANT PROGRAM CITY OF DECATUR, ILLII�FOIS _ 5. The project is to permanently retrofit three flood-prone single-family residential structures to reduce the future flood damages as elevation type projects. The elevation may be achieved by means of physically raising the structures or constructing a levee or floodwall to protect these structures. All three residences are essentially concrete slab-on-grade structures which will require that each be investigated by a structural engineer to determine the feasibility of physically raising the structures. If it is determined that one or all of the structures cannot be structurally raised, the next alternative would be to construct a levee or floodwall around the structures. It is recommended that a cost analysis be dor.e for each structur�for both of the finro retrofit options to determine the most cost effective method. The first residence is a single story structure located at 1750 South Commonwealth Avenue, owned by Robert E. Stewart, Jr., and approximately 1,100 square feet in size. The second is split-level structure located at 4013 E. Maynor Street, owned by Charles & Diane Smith and is approximately 1,900 square feet in size . The third residence is a single story structure located at 1725 S. Baltimore Avenue, owned by a Mr. Tim Adams and approximately 670 square feet in size with a detached garage. Location maps.are provided in response to Item 19 of this application form. � 6.a All three residences experienced shall flooding (less than 12 inches). The flooding damages the flooring and/or carpeting, personal property sitting on the floor, interior - walls and wall coverings, creates personal safety issues associated with electrical appliances and circuits and home HVAC systems. In addition, it causes problems with mold as a result of the moisture that may seep into insulation and the walls. b.These structures will typically be flooded for less than d �ay unless the flooding is sustained by continuing rains or storm water runoff cannot recede. in a norr�.al manner. c.The structures are not in a designated 100-year floodplain or near a creek, river or lake that contributes directly to the flooding problem. These structures are in an area that has minimal topographic change and were originally constructed with limited consideration to providing an elevation difference to the adjoining ground to prevent the flooding problems that occur. This area is prone to flooding from heavy rainfalls or-from extended wet periods that effectively result in heavy storm water runoff. The roadside ditches and drainage outfalls in this area have lir�ited capacity which may contribute to the flooding. 7. The benefit of this project is primarily property protection and the associated , economic benefits to the property owners in not, on a recurring basis, having the - personal expense of replacing and restoring personal property and the personal loss of time away from work to remedy the problems caused by flooding. There are also economic benefits to be realized by the property owners and the public through the long term, potential savings in flood insurance and flood damage claims by not having these properties "perpetually exposed" to flooding damage occurrence�. There are potential, life saving benefits as the result of residents in these structures not being exposed to the electrical dangers that may result from the flooding in their homes. There are potential environmental benefits associated with the problems associated�with excess humidity in a home causing mold problems and the potential contamination of home plumbing systems and possibly the public water supply system. � Page 1 �~t :
