There was a CLOMR and our ordinance has a two expiration, not indefinitely. Also, the 2001 FEMA
maps show the floodplain elevation has risen in this area. The maps are confusing but if you look at
the stream profiles, in 1994 the 100 year was at about 446 and at the same location on the 2001 profiles
the 100 year elevation is 447. The area I'm looking at is between 2150' and 4250' upstream of the
confluence of Denton Creek with the Elm Fork.
It's my opinion that there maybe some part of the prior study that could be savaged but there does need
to be a new study. We can talk about the concept of a LOMR-F vs. a CLOMR and a LOMR. But, I
would be derelict in my duties as a Certified Floodplain Manager and the Floodplain Administrator for
the city to allow a development to be built below the current floodplain elevation.
I would be happy to met and go over this in greater detail.

Ken,
I understand that you have spoken to Jason Rose and Mark Haas about this
tract. We dug out our old files on this site. It looks like we got a CLOMR
and CDC permit in 1997. Most of the fill was placed, with the exception of
the drainage Swale. The required excavation was apparently not done. Our
hope is that the approved work could be completed along with the design and
installation of a storm sewer line to replace the Swale. Then, at the
completion of the work a LORM-F could be requested. It is my understanding
that neither the CLOMR nor the CDC permit expire.
What are your thoughts?
