1. Nathan Davis Steven Reid Kristen Ulmer Graduate Assistant: Nathan Dye

2. N Design a stormwater drainage system for the city of Bluffdale Assess current infrastructure Assess current drainage needs for a 100 year 24 hour storm Design of new infrastructure using EPA SWMM Prepare a cost estimate

3. Map of Existing Inlets and Pipe Locations

4. 3 Drains in Neighborhood 1 drain has no pipe exit 2 drains empty into trench  9 Drains on Northern Street Pipes over to Bangeter Highway system

5. STEPS  Create drainage basins for each inlet  Find the depth of the 100 year 24 hour storm  Calculate flow lines and accumulations  Calculate curve number using soil type and land use data  Export information into HEC- HMS Map of Drainage Basins
