An existing 445 linear foot bolted steel plate and corrugated metal pipe culvert under 22nd Street/Locust Street and outfalling into the Fairmeadows Park requires evaluation due to condition issues.  Based on deficiencies found with the culvert, feasible solutions along with associated cost estimates to repair and/or replace the culvert are being developed.  The project also includes inlet and outlet protection at the culvert, low point drainage improvements on 22nd Street/Locust Street; and the removal and replacement of approximately 20 linear feet of 48” diameter corrugated metal pipe outfalling at the same location as the culvert under 22nd Street/Locust Street.  LT Leon is responsible for Alternatives Analysis, Preliminary Plans, Final Plans, Specifications, Bid Letting Services, Construction Administration and Resident Engineering.  Services include project management, data collection, base mapping using City provided GIS data, hydraulic and hydrologic analysis, and cost estimates.

HEC-HMS, HEC-RAS, and xpswmm-2D were used to model the existing and proposed storm sewer systems.
