General Project Narrative: Replacement of culvert 128 over Elk Creek on SR 1433 (Pucket Road) - The existing structure is a 23'-2" x 14'-0" Oval Metal Pipe with mitered inleUoutlet. The recommended
(Description of Minimization of Water replacement for these structures is a single Corrugated Aluminum Structural Plate Pipe Arch 24'-3" x 15'-10" with headwall and endwall. The existing channel varies in width
Quality Impacts) from 15' to 30' through the project site and stream banks are steep and deep. The existing culvert is perched. The recommended culvert will be buried and fitted with sills at the
inlet and outlet. No low flow notch will be provided since sill width is similar to stream width. The banks of the floodplain bench will be laid back at 1.5:1 and lined with class II
rip rap. The existing drainage patterns will be maintained through the existing ditches. All existing outfalls are stable except in the NW quad. The NW quad ditch will be
stabilized with rip rap to the stream.
