<br />Gregg,
<br />
<br />Thanks a lot for the evaluation. The council and parks folks are going to meet on site at 6:00 on Wednesday the
<br />26th. We would love to have you there if you could make it. If you want to bring your power point, we could
<br />view it at the council meeting afterwards (7:00).
<br />
<br />A couple of things I could clarify for you:
<br />
<br />. Side slopes of the rain garden were only recently planted and haven't had much of a chance to fill in. We
<br />do, however, plan to add some more plantings to areas without plants.
<br />. The rain garden has been draining in sufficient time since we modified the drain tile outlet. Originally, the
<br />draintile ran into the outlet structure. The invert of the outlet structure, however, was higher than the
<br />draintile violating the old rule that water does not run uphill. Since we bypassed the outlet structure and
<br />took the draintile into the swale to outlet, the garden has drained properly. It was during this time that the
<br />rain garden drain tile was not functioning, that most of our plants died. We plan to replace those plants
<br />(some in kind because we think they will survive now that the rain garden is functioning properly and others
<br />we will replace with more hearty species such as those which have made it despite the prolonged
<br />inundation).
<br />. The floating silt curtain has never been meant to be a wave breaker and has caused us a lot of headaches.
<br />It's there as part of our temporary erosion control plan. We will be removing it soon.
<br />
<br />Thanks again. We will run some of your suggestions past the council and parks board to see if they would like to
<br />install those items.

<br />
<br />Mark,
<br />
<br />Thanks for the call.
<br />
<br />I had gotten a chance to go out to this park on Centerville Lake last Friday (9/14), along with my co-worker Shawn Tracy.
