Re: Big Cedar Addition
Traffic Detour Plan
Dear Mr. Griffin:
We have reviewed the revised Traffic Detour Plan for the closure of Bethal
School Road prepared by Goodwin and Marshall, Inc., in connection with the
construction of the Big Cedar Addition. The traffic detour plan has been
revised in conformance with our review comments dated December 12, 1991.
We have discussed the Bethal School Road closure with Richard Wagle of Goodwin
and Marshall. They have indicated to us that they would like to implement
this plan as soon as possible. They are scheduled to complete the utility
work this week and start grading the streets.
It is our understanding that the plats and field note descriptions of the
public right-of-way which is to be abandoned across the McDowell property has
been submitted to your office for review. If you need any assistance in
reviewing those documents, please do not hesitate to contact us.
We are available to discuss this project further at your
Enclosures
