RE: Preliminary Plat Comments for Cornerstone Commercial Section II
;I
Dear Natalie:
Attached are the revised Preliminary Plat and the revised Master Development
'~ Plan for. Cornerstone. Commercial Section II. The following will address any comment
we were unable to address:
The northernmost driveway along Woodcreek Drive has a width of 45' including
a 5' median in the center of the paving. The comment and City ordinance call for a
maximum of 36' for driveway widths. In August of this year, we met with city staff
members. regarding this project, and Paul Kaspar mentioned that since we have. a median,
we can exceed the 36' max. ordinance as long as each side had a minimum width of 20':
In addition to following this stipulation, it meets all other driveway requirements (i.e.
offset distances, throat length, etc.).
There is a temporary drive. on the southeast. side of Woodcreek that does not meet
the: offset requirements with our proposed drives. However, also during the
predevelopment meeting with city staff, it was commented that this does not propose a
conflict due to its temporary nature.
We did not show any additional, drives or streets along the frontage road. The
ordinance calls-for a minimum offset distance of 275' fore a major arterial and the closest
drive. would be the on-ramp to Hwy. 6 which is approx. 500' to the. south.
Detention areas for Lots 1-4 are shown on the Master Development Plan. All four
lots will belong to the same owner, Centex Senior Services Corp., .Inc., but they. are
divided four ways because the development will be in four phases. This said owner
would be responsible for the maintenance on the detention areas during and after
construction. As the contours show, there is a ridge that follows. the lot lines between.
3&4 and 55&6 pretty close. This ridge means that the drainage for lots 5 & 6 are separate
from the other four. The storm water drainage for lots l-4 will flow to the detention areas
while lots 5 & 6 flow out onto the frontage road and the bar ditch that currently exists.
Any detention needed for lots 5 & 6 will be addressed when those lots are developed.
We do not wish to participate in the regional detention. It is our understanding
that we would still have to drain'into other people's property to get to this regional
detention area. While we are for regional detention and would have contributed if
situations were more simple, but it would not be cost efficient after having to please these
property: owners on methods to get to the detention area.
The detention area on lots 2 & 3 will primarily consist of a berm ranging from 1'
to 2' in height. Water will exit through 8"PVC pipes spaced evenly throughout the berm
to match the flow that currently: exists for the undeveloped site.- Calculations are shown
on a separate sheet to show the undeveloped flow and how much will need to be detained
to .produce the same flow after development.
Again, the above mentioned should be everything that. could not be addressed on
the Preliminary Plat and/or the Master Development Plan. I hope I have answered all
your questions tothe completeness that they were intended.. I would be happy to answer
any questions prior to or at the Planning and Zoning Commission meeting.
Thank you.
Sincerely,.
Dowd ,Anderson & Assoc.
Daniel L. Heischman, E.LT.
Please feel free to contact me with any questions or comments regarding the contents of
this letter. I look forward to presenting this Preliminary Plat and Master Development
Plan to the. Planning and Zoning Commission on Thursday, Oct. 1.
Calculations for Proposed Detention Area:
Using the Modified Rational Method for Detention Basin Design, we calculated the volume
required to detainenough water to keepthe developed flow equal to the undeveloped flow..For
our calculations, we used intensities (based on TP-40) and runoff coefficients found inane
College Station Drainage Policy. and Design standards. The following is the calculations for
detention volume:
Given: A 7.630-acre site into developed for commercial use (assisted living centers,
etc.). An area of 2.643 acres has contours which shows flow into the frontage
road of Hwy. 6. The remaining 4.987 acres flow into an adjacent property to the
north. This is the area for our calculations
Determine: Maximum release rate and required detention storage.
Solution: 1. Determine 100-year peak runoff rate prior to site development. This is the
maximum release. rate from site after development.
2. Determine inflow FIydrograph for Storms of various durations in order to
determine maximum volume required with release rate determined in Step 1.
Step 1.
Present Conditions Q =CIA
C = 0.35
T~ = 20 min.
hoo = 9.3 in/hr
Qioo = - 0.35 x 9.3 x 4.99 = 16.24 cfs (Maximum release rate)
.Step 2.
Future Conditi ons (Assisted Living Centers)
C = 0.60 (Avg)*
T~ 20 min.
hoo = 9.3 in/hr
Qioo = 0.60 x 9.3 x 4.99 = 27.84 cfs.
* Average: Pavement,, Rooftops, etc. C = 0.90 Area = 1.87
Undeveloped C = 0.35 Area = 3.12
Ca~g = [(0.90 x 1.87) + (0 .35 x 3.12)] / 4.99 = :0.60 (0.56)
.Check various duration storms
20 min. I = 9.3 Q ' = 0.60 x 9.3 x -4.99 = 27.84 cfs
30 min. I = 7.4 Q _ 0.60 x 7.4 x 4.99 = 22.16 cfs
40 min. I = 6.2 Q = 0.60 x 6.2x 4.99 = 18.56 cfs
SO min. I ='S.5 Q =. 0.60 x 5.5 x 4.99 = 16.47 cfs -
60 min. I ='4.8 Q' ` _ 0.60 x 4.8 x'4.99 = 14.37 cfs
70 mina L= 4.4 Q = 0.60 x 4.4 x 4.99 = 13.17 cfs
Maximum Storage Volume is determined by deducting the volume of runoff released
during the time of inflow from the total inflow for each duration.
Inflow = Storm duration x respective peak discharge x 60 sec/min
.Outflow _ Half of the respective inflow duration x control release discharge x'60
sec/min
20 min Storm Inflow 20 x 27.84 x 60 sec/min _ 33,408 cf
.Outflow 0.5 x 40 x 16.24 x 60 sec/min = 19,488 cf
Storage = 13;920 cf
30.min Storm Inflow 30 x 22.16 x 60 sec/min = 39,888 cf
Outflow 0.5 x 50 x 16.24 x 60 sec/min = 24.360 cf
Storage.. = 15,528 cf ~
40 min Storm Inflow 40 x 18.56 x 60 sec/min = 44,544 cf
Outflow D.5 x 60 x 16.24 x 60 sec/min = 29,232 cf
Storage. = 15,312 cf
SO min Stonn Inflow 50 x 16.47 x 60 sec/min =
Outflow 0.S x 70 x 16.24 x 60 sec/min =
Maximum volume required is 15,528 cu. Ft. at the 30 min Storm duration.

Subject: Developments at Woodcreek Subdivision
Shirley:
Thanks for talking with me recently and again today about possible new uses
of property nearto or in some way relevant to residents of Woodcreek
Subdivision. As you know, my specific responsibility is to keep members of
the Stonebridge Homeowners Association informed about possible developments
relevant to their interests.
In our recent conversations you discussed two new possible developments.
The first possible development we discussed was the planned construction of
an office building for McClure. Engineering:, Inc.. My understanding is that
this new building will be located on the site of the present TAG Realty
temporary .office building. Although t have not seen any site plan for this
new building (Is one available?), the impression I received from you is
that construction work on this project will begin soon.
The second possible development we;discussed concerned preliminary plans to
build an assisted Iivinglalzheimers facility at the entrance of Woodcreek
Subdivision. This possible construction is;likely to generate substantial
interesf among Woodcreek Subdivision residents.
F would like to use this a-mail to summarize. my present understanding of
that possible project. Here is my summary.
4: At this point in the planning, if the facility is developed, preliminary
plans call for it to-be developed on 4 of the 6 C-1-zoned lots located on
the northside of Woodcreek Drive and going. east on Woodcreek Drive from the
Woodcreek Subdivision entrance to the beginning of the Woodcreek
Subdivision property line.
2. Since the 4 lots on which the facility.-may be developed are zoned C-1,
no<further public notice or hearing currently is required or planned. This
is the view you expressed, I` believe, and your reasoning supporting that
view is that the C-1 zoning .allows for the construction of, among other
things, hospitals and medical: facilities with no regairement #hat the
developer obtain a "conditional use permit."You indicated. that if a
conditional use permit for the development were required-.then a-public
hearing would be required on the development. Shirley, since #his is a
crucial ,point, would you please keep me informed if there is any change in
your view of this,: or if there is -any step that. might be taken hat would
allow for a public hearing? Arguably, `some Woodcreek residents may have an
interest in the possibility of expressing. their views at a public.. hearing.
3. You indicated to: me that 1, through e-mail,. could contact yowr office
on Thursday of each week as a way of keeping informed about progress on
this development. The significance of Thursday as a day`for the e-mailing
is that you indicated that new plans for development can be filed with your
office by any Wednesday. Therefore,-your office would know on Thursdays if
any new plans had been filed on thisdevelopment. if my interpretation of
this.. process is correct, you can anticipate an a-mail from me on Thursdays.

Shirley, I have used this a-mail in part as a way of summarizing my current
understanding of the status of the assisted living/alzheimers facilty that
may be developed at the entrance of the Woodcreek Subdivision. At your
convenience, would you respond to this a-mail with: any modifications or
additions you think might be helpful to .meeting my responsibility (to the
Stonebcidge Homeowners Association) for keeping informed about this
possible development?
Thanks, Shirrley, for your continued help with and concern about the
interests of the residents of the Woodcreek Subdivision.

RE: Impact Studies
Dear Natalie Ruiz:
The proposed development should not have any unanticipated impact on utilities, traffic, etc. The area is
zoned as C-1, which our project is currently under. The. existing utilities that surround the site, to my
understanding, were built to accommodate this use. Moreover, our parflcular use would impact the water,
sewer, electric, etc. less than would an average C-1 type project. The future development in lots 5 & 6
would still meet the proposed C-1 zoning and no extraordinary usage should occur. Assisted Living Care
Facilities draw very little traffic and should not be any burden. on the community as far as traffic.
If you have any questions, contact Daniel Heischman or me at our office.
Sincerely,
~~
