Eric -
Thanks for letting me know. That looks like a pretty fair compromise.
Not only am I happy, but I will tell you that the paper would probably have a field day
with ( "geothermal system destroys area blackberry picking! "), not to mention some
important remnant native plants and wildlife habitat. Thank you for bringing this to the
committee. I can put together some recommendations for native plantings /seeding in areas
of disturbance once the construction has been completed. Protective fencing will also be
necessary between native plants and trees and the construction activity.
My foot is doing o.k.. The surgery went fine and I stopped taking pain meds by Sunday, so
life is good. Cabin fever will probably be my worst problem. My husband got me a
walker /scooter that I can rest my bad leg on and scoot all over the main floor. It's
definitely better than crutches! You'll be happy to know that I will soon (next week) be
finishing the OPH 2008 report and 2009 work plan. When I can walk better on crutches (or
my own foot) I'll be back to staff meetings. Probably 3-
4 weeks. Let me know if you need any other tree or plant info.. Say hi to the gang there.

Subject: Geothermal Wells and Ponding Under Power Lines
Eric -
After looking at the most recent proposed plans for the OPH City Hall construction
today, it is apparent that the wells for the geothermal system as well as a stormwater
pond are planned for the area on the north side of the trail under the power lines behind
the current City Hall. This is an area which has a temporary vernal pond and also a
number of different species of remnant prairie plants, both herbaceous and woody. I have
not done an inventory of plants or trees in this area, or in the area east of the trail
behind city hall, since I was not aware of any construction activity in those areas. The
area east of the trail behind City Hall has a lot of tree cover, which will provide
screening for the residences to the SE of the new City Hall. If the geothermal system and
ponding cannot be put on the southern part of the city property, then it would be better
to put them in the open area under the power lines, but perhaps the area of construction
could be minimized.
It would be a good idea to check the MN County Biological Survey data for any rare
plants in the proposed construction area. It also would be a good idea to have the
remnant area assessed by someone highly experienced in native prairie and wetland species,
such as Jyneen Thatcher of the Washington Conservation District. Unfortunately, I will be
having foot surgery 2/5 and will not be able to be involved in any inventories or
assessments in these areas until probably April.
