RE: Erosion Complaint
Subject: Northlake Industrial Park 27 Acre Tract
Date: April 20, 1993
In November, 1992 we made a site investigation at 245 E. Bethel Road where a tributary of
Grapevine runs across the back of said lot. This visit was requested by Mr. Ed Spalding, who is
concerned about the amount of drainage outfall associated with the light industrial tract (LI tract),
running through his back yazd causing erosion and sedimentation problems.
I wrote a letter to Mr. Bill Thompson in December, 199,Z,urging him to address the above concerns
and suggested a meeting among affected parties. After several follow-up calls to Mr. Thompson
and his engineer, and through an exhaustive effort, I was finally able to conduct such a meeting on
April 16, 1993 at 8:30 a.m. Attached is a list of persons who attended the meeting.
Mr. Spalding, (residing at 245 E. Bethel Road) and Mr. Young (residing at 236 E. Bethel Road)
are looking for some type of temporary, followed by a permanent, solution to reduce the discharge
rate and it's velocity before it leaves the LI tract.
Although there were some arguments as to who is to blame and/or what the ultimate solution should
be to handle the water flow, etc., Mr. Thompson and his engineers agreed to take action and
provide some type of an acceptable erosion control measure on his property, as an interim solution.
I expressed my concerns to Mr. Thompson about the unreasonable delay in correcting the problem
which was brought up in June, 1992. I indicated that it is our desire to work with Mr. Thompson
and his engineer, as long as the above concerns aze addressed immediately and a plan of action is
submitted to the City no later than May 6, 1993.
It is my understanding the LI tract has recently been seeded and that currently there is a 25
vegetation on the property, according to Mr. Garrett, of Nathan D. Maier Engineering. I requested
an erosion and sedimentation control plan be submitted to the City, which is to provide a solution
to this temporary/semi-permanent condition on the undeveloped property.
In general everyone was in agreement that increased drainage along this tributary can cause
problems and Mr. Young even suggested that individual affected home owners should participate
in solving erosion problems in their backyards as well.
I am currently preparing a letter to Mr. Thompson as a follow-up to the above referenced meeting
and will keep you informed of the progress. If you have any questions please let me know.
