Dear Mayor Lehman:
recent meeting of the Board of the Johnson County Heritage Trust we discussed the
proE~sed amendments to the Sensitive Areas Ordinance which would allow for more Site
Plaf,~ to be reviewed by the Planning and Zoning Staff rather than going through the
lon~ ~ :pf public review.
I therefore called Bob Miklo at Planning and Zoning, and he sent me a
proposed a~ended Sensitive Areas Ordinance and a summary of it and rational for the
changes. Later~ g~ ~ lengthy~iEformative phone co~go~n.
My conclusion is that in general the proposed changes make sense. They would simplify
the review process and in most cases save the City Council's time.
We wogl~ ~ tC~ ~ ~, ~9~ver, that the public is still informed of all requests
to see and comment on them to the Pl~m~ and
Zoning Commission and to express comments m ~ Cou. ncil. It is very impo~h~i t6
maintain openness, not only to prevent closed-door 3~{~i~fi~ bul ~!so fo~ ~ 8ensitive
Areas Ordinance to remain effective. When it comes to protecting woodlands, wetlands,
prairie remnants, archaeologic~ ~i~§~ ~nd hillsides, all of us have an interest. Moreover,
So, as I say, we accept the proposed amendments to the Sensitive Areas Ordinance. But
we also want to be sure, that the n~ti**~ ,o~ still be given of all reviews of Site Plans.
Please make sure that all members of the Council receive this letter.
Sincerely,
Robert F. Sayre
President, Johnson County Heritage Trust
