IMPERVIOUS SURFACE LIMITATIONS <br />The use of a sliding scale for impervious surfaces is a part <br />of the comprehensive water quality protection package for <br />University Lake watershed. It is not clear from the state <br />rules that such a sliding scale, based on lot size, would be <br />. .......... ........ <br />. es:. <br />.r r ri py-id.e. <br />P a­:4­`4,�]��!� Co : un 't the ��!zx <br />.:.: , , . .................. . ­ ..

The WS-4 category, which provides few limitations <br />on non-residential development, would seem more appropriate <br />for this sort of interpretation. <br />S.- DENSITY OF DEVELOPMENT <br />The rules state that local governments, in meeting the <br />watershed density standards, can regulate either by using <br />minimum lot sizes OR by limiting impervious surfaces. <br />Many local governments in this area, including orange County, <br />link these two concepts and utilize both approaches az one. <br />6.
