Re: Drainage on and across 272-274 Southwestern Blvd.
Dear Ms. LaGrone:
I have reviewed the information provided to me concerning improvements on the referenced
property. I previously requested that a site plan be provided showing the location of the various
pipes and inlets as shown on the pictures provided. Recently, a blueline print was provided to me.
However, it was only a copy of a print that I already had in my possession in a packet of
information previously provided to me. The blueline print does not show the location of any of the
proposed pipes or inlets. I have tried to look at the blueline prints to determine where the various
improvements will be. To the best of my ability it appears as though there will be two inlets placed
on the parking lot of the adjacent property and a pipe running from the west to the east across the
northern end of the parking lot. This pipe will then discharge into an existing ditch/swale on the
west side of Pinkerton Elementary School. In looking at the size of the inlets and pipes, it appears
as though this is nothing more than a solution between two property owners to rectify a drainage
problem. Therefore, the following needs to be complied with prior to the City giving approval to
proceed:
1) A site plan showing the location of the pipes, inlets, sizes of the pipes and inlets, discharge
point, etc., needs to be provided to the City;
2) Permission from the property owner on whose property this will be located will be
required;
3) Permission from the school to discharge the water into the existing swale will be required.
This permission is necessary because it appears as though the water naturally drains from
the parking lot back to the west, not to the east. Because this naturally drains back to the
west, have you considered discharging the pipes back to the west into existing Grapevine
Creek? This would save the necessity of contacting the school to discharge the water onto
the school property.
As I stated, this will be a private drainage solution between two adjacent property owners,
therefore, no drainage easements will be required.
Once you have submitted the above information and I have approved it, then you will be allowed to
proceed with this drainage solution. It is important that you have the approval of the adjacent
property owners prior to beginning construction.
If you should have any questions or need any additional information please feel free to contact me
at your convenience.
Sincerely,
Kenneth M. Griffin, P.E.
Assistant City Manager/City Engineer
