Mechanicsville has obtained a grant under the Federal Program for Urban Development of Greenspace and the Environment to build a condominium complex for the retired. The total land set aside is 74,010 m2. Of this area, 15,832 m2 will be used for Swiss chalet condominiums with slate roofs. Public streets and drives will occupy 18,886 m2. The remainder will be lawns. The area is flat and has sandy soil.

Using the most conservative estimates of C, find the peak discharge from the development for a 2- year storm. Assume an overland flow distance of 272 m and use the IDF curve given.
