EXHIBIT 2.05-E3
DRAINAGE AND SEDIMENT CONTROL PLAN
TABLE OF CONTENTS
INTRODUCTION
This exhibit contains all Drainage and Sediment Control (DSC) calculations Erom Appendices B, B 1, and B2 of the
original permit for those drainage structures' which still exist except for those structures which have been modified
and the original ealcula[ions superccded by new calculations. This exhibit also includes all revised design
calculations for evsting stmctures that have been modified and new design calculations for those structures added
subsequent to 1992 All DSC calculations Eor struttures or Small Area Exemptions (SAE's) which no longer exist
or have been superccded by new DSC calculation have been eliminated. Exhibit 2.05-F_3 is organised and
