Drainasa in the Alley of 141 Hill Drive - Mr. C, ary Hayrick
This is in response to the January 5, 1989, memo to you from Couucilsmn
Morton, (Copy Attached), requesting assistance for Mr. Hamrick.
I had received a similar letter (Copy Attached), and had contacted Hr.
8amrick. Steve Coram and I mat w~th Mr. Hayrick at hie property on
Saturday morning, January 7, 1989, at 7:30 a.m. We discussed the
situation and circumstances with Hr. Hamrick, and told h~m we would
further investigate solutious available to improve the drainage behind
his home. However, that investigation will be extremely limited, due to
the available resources (i.e. staff and funding). These limitations are
also due to the technical nature and complexity of the matter. The
situation is that he alley behind the residences (141 and 145, etc.) on
Hill Drive, does not properly carry the stor~ water, and it therefore,
overflows into driveways and garages. (And, as Mr. Hamrick states, the
home at 145 Hill Drive floods). This discussion is based upon the
information that Mr. Hamrick provided Hr. Gorom and myself last Satur-
day.
The alleyway does not properly carry the stormwater past Mr. Hamrick's
driveway. ~he alley must not have been designed and/or constructed with
sufficient slopes to carry the stormwater along the alleyway, and into
the inlet behind 145 Hill Drive. What happens, according to Mr.
Hamrick, is that the water ponds near his drive, and over flows into his
driveway, while only a small stream (not the entire alleyway width) of
water carries the water from that ponded area behind Hr. Hamrick'e
drive, down to the inlet behind 145 Hill Drive.
Mr. Hamrick further states that some four to five (4 to 5) residences
have placed speed bumps at the inside edge of their garages to keep the
storm water from entering their garages.
~at needs to be done, is a detailed topographical survey identifying
the grades and slopes in the area, along this alley. Then an engineer-
ing review needs to be made to see what i~provements "could" ba made,
given the conditions (elevations of the surrounding homes and driveways,
alleys, etc.). This effort would require a land surveyor crew and
survey equipmant, and could cost in the range of $1,000 or more. We do
not have any survey equipment, and Ginn, lac. contracts their surveying
out, because it is not cost effective for them to maintain a survey crew
full time. However, we will review the "as-built" subdivision drawings
to see if there is any relief (~uick-Fix) possible.
! have reviewed the July 12, 1988, storm file of flooding reports, to
the Planning and En8ineering Department by the Police and Public Works
Departments, as well as phone calls directly received by us. It appears
that with the exception of the reports to the Public Works Department
for Iii and 145 Hill Drive, thsre were no othsr calls, nor documsnta-
tiou, and there are no claims/suits on file in ths City Sscretaries
Office for either Ii1 or Iii Hill Drive. Last Saturday Hr. Hamrick did
say that various garages do flood, and that his nsighbors at 115 Hill
Drivs (listed on the water billings as Susan Robsrtson) had flooding in
her home, as well as carpet damage. I recall investigatin$ a drainage
complaint at 145 Hill Drive (not necessarily related to the July 12,
1988, Storm). I "recall" storm water up to the house, but do not recall
any damages.
Mr. Hamrick's letter addresses the attention the Pelican and Bethel
School Road drainage situations are getting. This is because there was
clear, well documented structural/residential flooding and damage,
accompanied with numerous claims and citizens petition. That is why
those two arsas were recommended for study and improvements to their
storm drainage systems.
Attached is a copy of the recent 8,,~ary memo concerning Iii Hill Drive,
from the Public Works Department. The grinding of the groove in the
alleyway to try to improve Hr. Hamrick's ponding problem wes, and
probably still is, the best quick-fix solution with the current condi-
tion and rssourcss available.
As mentioned before, we will review the as-built construction drawings
to see if any quick-fix options are available.
