" Water available for mitigation will probably support the range of .33-.40 Acres of
mitigation based on the hydrology information we have to date.
ALTERNATIVE MITIGATION IDEAS
1. Temporary surface irrigation (sprinklers with surface pipes) to help the new
wetlands get established.
2. Mitigate with a substantially higher quality of wetlands rather than using a higher
mitigation ratio (i.e. provide more quality rather than more quantity).
3. Consider Natural Resources or Parks recommendations for possible off -site
wetlands mitigation which would be in the public interests and in lieu of some of
the Redtail mitigation requirements.
4. Hire a professional company to complete an ecological cleanup and
enhancement of the three ponds, as necessary and with approval from Natural
Resources, so they are healthier ponds and can better support fish, birds, and
other wildlife.

Re: Redtail Impacted Wetlands / Recommended Mitigation
1. By moving the waterline approximately 20' north, we avoid almost all of the
wetlands impact in a very sensitive area which was occurring at the north end of
the middle pond previously in our Submittal #3.
2. Please see the enclosed plan, which identifies for you the seven impacted
wetlands. And in relation to that please see the enclosed table describing each
respective wetlands size, quality, recommended mitigation ratio and
recommended mitigation required.
3. Also see the enclosed table showing the maximum mitigation area on site which
we believe is possible to achieve, the amount of new wetlands which we
probably have sufficient water to support, as well as alternative mitigation ideas.
4. Disturbances in wetland areas in #2 and #3 are for the purpose of emergency
public safety activity (emergency access road), utility installations that cannot be
reasonably located elsewhere (water line) and construction of a pedestrian
walkway that will provide public access for educational purposes, and therefore
we would request that these disturbances be allowed and consideration be given
to not requiring or reducing mitigation for same.
