in terms of dollars, 1% of the value of the shopping center to
keep the storm water away from one intersection, and he feels
that this is getting too severe for him to bear.
Adm. Achen asked if he knows whether there is a 100 year capacity
on the site now and Mr. Gottsacker replied that he can say positively
there is no longer 100. He stated that he was surprised to find
that the actual capacity of the ponds is close to their original
capacity. The administrator asked what would the cost be to build
those ponds as you designed them and Mr. Gottsacker replied
that he would have to go back and calculate. He would not venture
a guess at this stage. Adm. Achen asked if the erosion problem
that is apparent has reduced capacity of those ponds from the
original construction? Mr. Gottsacker replied, very little.
Adm. Achen asked if it was his original design that 2/3 of the
drainage would go to the N.W. holding pond? The reason he
asked was because that was what the situation was when they
encountered the situation. Mr. Gottsacker replied that the drainage
line splits almost into two equal triangles. Looking at the
site the split in the parking lots is the same. The big difference
is what is coming off the roof. Adm. Achen said that in your
original design you did not intend to have that roof drain off
there and Mr. Gottsacker said that it was supposed to be released
slowly later after the storm passed. They did not discuss how
it would be accomplished. Mr. Paster is willing to pay something
for the ditch, the matter of how much is to be negotiated. He
does not feel that the benefits received are equal to the number
of dollars. Atty Meyers asked what the simple solution was?
Mr. Gottsacker replied that the ditch had to be regraded to
some degree. In July had they lowered the culvert just some,
regrading would probably have solved the problem, as water tends
to stand but goes away fast, too. That would have been a reasonable
solution.
Atty Meyers inquired as to whether the installation of a culvert
would release some of the water and Mr. Gottsacker replied,
definitely, if installed at the grade there would have been
some relief.
Adm. Achen asked him that, if in his professional opinion, by
not having storage on the roof, by simply installing a curb on
that driveway, and providing a straight -line grade, would that
relieve all flooding north of County Rd. I? Mr. Gottsacker
replied that it would not contain the kind of storms experienced
in the spring of 1975. Since then the catch basin has been
rebuilt, but it was reported that water was backing up from that
point. The administrator stated that it had flowed out of the
northwest pond to the east. Eng. Bearden inserted that all of
the water had flowed off the roof on the north side of the
building until the roof downspouts were altered to make it flow
off the east side.
Mr. Gottsacker stated that originally the developer recognized
some sort of problem would exist. We had some discussion of
