<br />
<br />Determines total growth capacity. requirements and the portion

<br />System Development Charge Methodology
<br />
<br />.Overview
<br />
<br />The SDC methodology for MWMC i$ based on a combined reimbursement and
<br />improvement structure, as shown in Figure 1. The methodology consists of the followirig
<br />elements: .
<br />
<br />. Determine capacity needs
<br />. Develop cost basis
<br />. Develop SDC schedule
<br />. Calculate revenue offsets and credits
