I assume that there would still be language preventing recreational structures, e.g. playground equipment, from being placed within the floodway portion of an allowed recreational facility use.

The IEPA standard for permitting composting operations in the flood fringe is above the 10 year flood elevation. The current Du Page County criteria is above the 100 year elevation. Should this be resolved?

With reference to Thomas Burke’s overview at the Municipal Engineer’s Meeting 7-8-2010, please consider two comments regarding proposed ordinance amendment language:
In 15-133.11 it is proposed to delete the language – ‘Compensatory storage shall be operational prior to placement of fill, structures, or other materials in the regulatory flood plains.’
I do not recall hearing Thomas Burke explaining the rational of this proposed deletion. In the case of a large, phased or long duration project that requires flood plain compensatory storage or for that matter detention, allowing fill and structures before the comp storage is in place or allowing siginicant work to proceed before detetnion is in place, would seem to create an exposure to flooding or damage to neighboring property. It is conceivable that without this statement, or some other language ‘trigger’ or language requiring concurrent work, that only ‘Final Occupancy’ would achieve permit compliance. The current language and similarly the current language in the detention requirements section of the ordinance, administered with reasonable Administer discretion, has protected neighboring properties from flooding caused by the impacts of the development. Having the comp storage or detention in place in the recent cases of failed developments has also protected neigboring properties.
In 15-133.24 – please consider including references to water treatment facilities and waste water treatment facilities and storm water treatment facilities to the list of ‘appropriate uses’.
