Attached is an email and PDF from Creekview showing how they want to add medians to portions of
Bethel Road in their subdivision. My response to their email is below.
If you have any comments are observations that I missed, let me know.
Thanks

The drawings and concept look ok to me. I do have a couple of observations: instead of trying to tell
how to construct the curb you should refer them to our standard details (we will enforce the standard
details during actual construction, regardless of what your notes state); we typically access a 4%
inspection fee for work in our right of way (there might be consideration given to waive this because
you are beautifying the area); we charge a tap and impact fee for new water services (this is based on
the irrigation meter size and there really isn't any way to waive it); the actual drawings will be
forwarded to our Planning and Parks Departments for comments (Planning reviews the aesthetics and
how it blends in with other areas and Parks reviews the type of landscaping and trees to ensure they are
on our plant palette and are compatible with the installation location).
The approval to perform the work will be granted via a License Agreement between the HOA and the
City. I present those to Council and make a recommendation. They are generally approved, however,
there have been a few denied. The ones denied did not have a positive recommendation when
presented to Council. Let me know if you would like a sample License Agreement forwarded to you.
If you have any other questions or concerns feel free to contact me at your convenience.

Ken,
Here you go. Sorry this took so long - I sent it earlier but I just noticed
that I had a typo in your address.
I just tried to call but the switchboard is closed. If you have time please
call when you get this so I can review it with you.
Thanks.

Ken,
Perhaps I looked at this a little too closely.
*The trees appear to be planted very close to the curb. We have experienced trouble with this type of
planting, especially in an already narrow median. The trees will quickly crowd the roadway and limit
access on the interior lanes (as can be seen on the submitted graphic).
*I would recommend that the trees be purchased as container grown material. A 65 gallon tree will cost a
little more than a 4" B&B, but the container grown tree has a much better chance of thriving quickly and
making a more immediate impact.
*Trees of the species indicated are typically not planted closer than 40' o.c. (exc. the Crape Myrtle)
*The Electrical should be 110 volt, not watt. Wattage will be determined by the service item. This system
should really be designed by an electrician-it is unclear as to the expectation in a "power box".
*The• 12" rise in the center of portions of the medians will likely be too much, causing the soil to erode
across the curbs. This will also create difficulty in mowing of certain areas and create dry spots on the
higher ground.

In the following aerial photographs of Bethel
Road around the Creekview entrance you will
see that Bethel Rd is much wider than
Meadowcreek Rd or the new extension of
Hidden Valley Drive (the new development
behind the First Baptist Church) which, like
Creekview is also a single entry neighborhood.

There is no place else in Coppell where the road is this
wide, this unsightly, and is so inviting for fast driving.
The interesting thing is that not only is 6ethel Rd
"SIXTY FEET WIDE" at the east end of the east island,
but it is still 60 feet wide where it intersects with
Glendale.

The new extension of Hidden Valley Drive (behind

to 6ethel, which is 60 feet wide.

2"° Island 12 X 56 = 672 SF including new curb
3RD Island 5.5 X 39 (optional island) SF including new curb
(Three Islands) = 2711 SF - (437 LF curb x 18") = 2055 SF of landscaping
Landscapers & Concrete: It's about 75 feet from the second existing
island to the 18t proposed new island, then about 100 feet to the 2"d
proposed new island, and then about 70 feet to the third (optional) island.
Concrete: Please line list the cost of saw-cutting and excavating a
shallow trench, installing a 4 inch PVC sleeve for the irrigation and
electrical and, repaving. Landscapers: Please line list the cost of boring
and installing the sleeve.
NN-NN-N---N- -NN----NN-N-M---N-NNN-NN--N---N------------
CONCRETE: REMOVE 2711 SF IN THREE AREAS: Saw cut existing
concrete at designated boundaries and excavate to 8" deep. Haul off all
debris. CONSTRUCT 437 L.F. OF NEW CURB FOR THREE ISLANDS:
Dowel into existing paving, form and install three bars of 3/8" steel rebar
along length of curb. Pour new curb to match existing an give rough
broom finish. Concrete should achieve a minimum compression strength
of 3500 PSI within 28 days.
LANDSCAPING: Please bid based on the attached plan. You are
encouraged to come up with your own alternate plan or make
adjustments to this plan as your alternated plan. Use as many Live Oak
Trees as possible and stagger them (one closer to the south curb, then
the next closer to the north curb and so on, but don't use two systematic
(try to give it a natu ral look. The base price should include the fastest
growing and largest starting size live oaks and then alternate prices for
one or more alternate sizes. Also as an option of going with Red Oaks for
the 2"d (center of new islands) in the three island version. The islands
should be mounded in the middle -rising at least 12" from curb.
Landscaping bids should include all irrigation installed, soil, plants,
ground cover, trees, and one 110 watt outdoor electrical power box for
each island. The quantities specified are anon-professional estimate.
Please calculate your own estimate and offer it as an alternate if it is
substantially different than mine.

UNIT PRICING (it is understood that if the scope of the work changes
substantially that your units prices may vary).
