Updated Task Chart
The main task at this meeting was working through the implementation strategies
and the task chart to make sure that there are no “red flags.” Dr. Gustavson
pointed out that a slightly amended version of the implementation strategies
chart along with a narrative to accompany the task chart had been uploaded
on the website.
The first question/comment pertaining to the new material dealt with Road
Specs (narrative) on page 4, specifically with the language, “Reducing the
size of paved surface.” The question arose if narrower roads are necessarily
safer. Dr. Gustavson pointed out that studies show that traffic slows
with narrower roads. Several committee members mentioned that a difficulty
arises here when also dealing with the road commission and county specs.
Some townships do not allow private road ordinances. Dr. Gustavson then
pointed out that this portion of the narrative would only be for more low
traffic areas and not through roads. Dr. Ohren suggested that the committee
be more specific then, about new development and paving in existing development;
perhaps the wording should refer to “roads in new housing (low traffic) development.”
All agreed that this would probably better capture the intent because developers
have to work with the road commission on these requirements.
Roger Bezek of Exeter Township then questioned the runoff strategies.
He mentioned that the discussion began with how they affected habitat; has
this been addressed enough or superceded by more important issues out of the
stream be itself? It became apparent he was concerned about flooding
and potential log jam removal. Dr. Gustavson explained that as a strategy,
we are recommending another hydrologic study that would include the upstream
area of the watershed that has been subjected to so much development.
The 1996 study that dealt with flooding ignored the impact of upstream development
as a potential problem for downstream flooding. He continued that streams
normally have some debris that is good for hydrology and habitat. In
addition, some log jams were removed this past summer. This new hydrologic
study could help us determine the impact of this removal and would help us
see whether or not there have been positive results. Most importantly,
the study would help us determine what parts of the watershed are contributing
to the flow problem most significantly.
There was some discussion among committee members about whether removing
all log jams would be the best action to take. Dr. Gustavson mentioned
that some may need to be removed, but cleaning the whole system would not
be in the best interest of the watershed. A new hydrologic study would
provide more information about upstream development and help with these very
specific strategies. Another concern expressed by committee members
was whether or if any type of future work such as removing log jams would
be supported. Janna Sebald informed us that in most of the literature
now, removing log jams is not specifically recommended unless there exists
a navigation issue.
Dr. Ohren suggested that recommending removal of log jams should be based
on the findings of the recommended study. Dr. Gustavson added that we
could take this study, recommend it for the whole watershed (rather than just
the upper watershed as originally envisioned), and include removal of jams
as a potential action strategy if the new study shows a need to remove some
of the worst log jams that are causing bank erosion or excessive blockage.
Kris Neuvrith then added that eventually we are going to have to sell this;
there has to be a balance between log jams and bank stabilization. Dr.
Gustavson added that the problem here is dealing with a nonpoint source –
the problem is volume of water, but in several ways this can increase both
erosion and sediment. This discussion ended with a suggestion to perhaps
provide a general statement about the importance of maintaining flow as a
part of bank restabalization.
The next topic was the issue of streams, channels and roadways. As
far as “altering grading practices,” are we referring to technique?
Dr. Gustavson explained that we have identified where problem areas are and
it is really up to the road commission to look at and check these locations
out. Dr. Ohren suggested that altering grading could encompass a lot
– how much, where, how, how often, etc.
Cheryl Baltrip then pointed to what she saw as redundant areas in the chart
and narrative. The first had to do with the alternative road specs on
page 4 of the narrative. Dr. Gustavson answered that the roundtable
was an attempt to get township officials to talk together and have some uniformity
in ordinances and regulations so developers wouldn’t come in and take advantage
of those units with limited regulations. Alternative road specifications
was one example listed that could be considered under the roundtable discussion,
but the topic was listed separately in order to allow townships to move forward
on the initiatives without the roundtable discussion. Second was the
change in Low Impact Development on page 1 of the narrative. Dr. Gustavson
added that “local” will be changed to “county or city.”
The next comment dealt with the paragraph, Reduce Allowable Drain Rate of
New Developments, on the first page of the narrative. Harry Sheehan
of the Drain Commissioners Office pointed out that the Drain Commission is
not engaged in reducing allowable drain rates. It was decided that this
paragraph should be stricken and Harry will assist us with a new one that
will include some detention standards. The problem of the absence of
standards can be identified in the paragraph; if a county has no standard,
then new development may not even have to have storm water management.
The last item questioned was wetland ordinances recommended.
States regulate 5 acres and above, but some local ordinances allow the regulation
of all. Dr. Ohren recommended then the adoption of local ordinances
by townships to regulate less than 5 acres. There existed some contention
within the committee as the issue obviously presented itself as property rights
v. control of growth and development. Dr. Gustavson pointed out that
these would only be recommendations; it is up to the individual townships
to implement action plans.
Concluding the meeting, Dr. Ohren suggested that we postpone action on the
documents at this point in time. We need to change some of this language
and get this back in front of everybody again in anticipation of the January
meeting. We need to go over the draft resolution to be presented to
township boards and the outline of what would be in the presentation.
Next Meeting
It was agreed that the next meeting will be on Wednesday, January 19, again
at 1:30pm in Exeter Township.
