The following summarizes the field review and meetings. Selected <br />photographs have also been included. <br /> <br />Meeting with Lafayette <br />. A meeting was held with Peter Johnson, City Engineer, on December 4, 2000 at 2:00 pm. <br />Chip Paulson and Tom Browning attending the meeting. Bonnie Starr is the Building <br />Inspector and actually has responsibility for enforcing the city's floodplain regulations, but <br />was out of town and could not attend the meeting. <br /> <br />. The primary concern with the floodplain designation for Lafayette is that there is a major <br />ongoing floodplain mapping process that will require a new designation once it is complete, <br />The concern relates to Bullhead Gulch, which is currently not mapped on the effective <br />FIRMs but which has since been studied by Taggart for FEMA. This flooding source was <br />identified by UDFCD in a master plan, and Lafayette has constructed a detention basin at <br />Baseline Rd and Highway 42 to address it. Revised maps were submitted to FEMA, but the <br />communities found errors that have not yet been corrected. Tom explained that if the new <br />mapping is incorporated in a LOMR, then it automatically gets rolled into the State's <br />designated maps, but if it is issued by FEMA as a restudy then the State has to rescind the old <br />maps and designate the new maps. Either way, there is no reason this has to hold up the <br />current designation process since it deals with the currently effective maps. <br /> <br />. Peter does not have many floodplain development problems. Rock Creek and Coal Creek <br />areas have generally been developed by large developers who have stayed out of the <br />channels. There is a Rock Creek - Coal Creek trail system that has created buffers in the <br />floodplains. . <br /> <br />G> <br /> <br />1019 <br /> <br />boulder _ co_fieldrpt.doc <br />November 13, 2000 <br />
