Fahey COUNCIL Jim LaValle Matt Anderson Riek Montour 13111 Illesener ADMINISTRATOR Joel R. Ranson Based upon the concerns raised at the Planning Commission meeting of July 8, 2004 regarding the Gervais I-Ells preliminary plat, staff conducted further review of your application.

This is to ensure that as houses are constructed, elevations will not be altered that will negatively impact the function of the grading and drainage plan. This is even a
