Question

A developer purchased a 120 acre land in a sub-urban of Akron, Ohio. The land was originally a range under a poor condition. The city zoning map shows a medium to low intensity residential zone for the division. He plans to build 220 single-family houses in this new sub-division. The new road will need 8 acres. The land management code also requires a forest preserve area for 20 percent of the total development area. What is the average size of each lot? What are the peak runoff flow rates before and after the development if the design storm is 25-year, 24-hour rainfall? The site center is located at the geographic coordinate 40.XY 50°N, 82.359°w. NOAA Atlas 14 rainfall data is required for the design (https://hdsc.nws.noaa.gov/hdsc/pfds/pfds map_cont.html). (Note: XY-last 2 digits of your Student ID number). 1. 4-0
