Preliminary Plat, Preliminary Engineering Plans and PD Zoning Site Plan for the Proposed
Big Cedar Addition to the City of Coppell
Dear Shohre:
Enclosed please find two (2) copies of the above referenced plat, plans and zoning site plan for the
proposed Big Cedar Addition to the City of Coppell. Please note that the items have been revised
per Development Review Committee comments. The following are specific items that I feel require
addressing in regards to the DRC comments:
1)

P~LIMINARYP~T
We are still showing the right of way of Harris Road (Bethel School Road) as fifty (50) feet.
This requires an additional 7.5 foot dedication from the subject property. As you are aware,
Mr. Tim House of Matthews Southwest Investments has been negotiating with the landowner
across Harris Road as well as the City of Coppell as to the issues inherent to the improve-
ments of Harris Road. Engineering documentation is being prepared by others to address this
issue. It is my understanding that this documentation will be presented to the City within the
next few days.
The ten (10) inch sewer line that traverses the property is not contained within any dedicated
public easement. For this reason, no easement is currently shown as existing on the
Preliminary Plat.
The twenty (20) foot private access easement across Lot 1 has been previously agreed to with
the McDowell family.
We are formally requesting a variance from the City requirement for alleys on this project.
This has been duly noted on the Preliminary Plat as well as the PD Zoning Site Plan.
We are currently in the process of determining our desire to access the park. This issue will
be addressed prior to filing a Final Plat. If we do decide to access the park, we will plat a
suitable easement between lots adjacent to the proposed park dedication.

PRELIMINARY DRAINAGE LAYOUT
We intend to design proper erosion control devices at the outlet of the proposed storm drain
pipe to serve the property. This issue will be handled during the final design phase of the
project.
As you are aware, we have proposed a reclamation project for this region. The City has
accepted the project and forwarded a flood study to FEMA for review. The DRC comment
requesting information on the proposed plan of improvements for the creek area in relation
to the Albert Halff study must have been made by someone outside the loop on this issue.
ff any questions remain, please call.
The flood study discussed in (2) above clearly shows that minimal impact of the reclamation
project is experienced at the proposed park location.
Area A5 as shown on the preliminary drainage layout is expected to be picked up in the future
Harris Road storm drain system. If there is a timing problem for the two projects, we will
accommodate the runoff through the concrete flume as shown.
We are proposing that the drainage easements be fifteen (15) feet in width. A twenty foot
easement would actually encompass more area than the side setbacks for the lots. We feel
that the fifteen foot width provides adequate access to the storm drain system.
We have included a watershed area map of the drainage basin clearly indicating the project
location.
PRELIMINARY WATER AND SEWER LAYOUT
We agree to show a 15 inch sewer line through the project as called for under the recently
completed sewer master plan. However, we feel that the over sizing of this line should be cost
shared by the City. Please advise as to how you wish us to proceed with this request.
The proposed sanitary sewer between lot 8 and lot 9 will be offset within the easement so that
the manhole can be access~ from one lot, i.e. no fence will cover the manhole lid.
The actual configuration of the connection to the existing sewer near the south property line
of lot 8 and lot 9 will be designed for the best possible connection angle. The complicating
factor in this situation is that an existing aerial crossing is in this location. During the design
process we will work with the City to establish the best possible situation given the eaisting
configuration in this location. For the purposes of this preliminary submittal, we have not
changed the configuration as originally submitted.
I have not included the fire hydrant at the intersection of Harris Road and proposed Brock
Street (Street "A"). All lots within this region are well within 500 feet of an existing or
proposed fire hydrant.

5)
Rather than add the fire hydrant at the end of Lcigh Street (Street "C"), we have moved the
proposed hydrant near the intersection of Leigh Street and Brock Street to a location that
places aH lots within 500 feet of the hydrant. Please contact me if either item (4) or (5) as
indicated are a came of problem to you. These issues can be worked out during the design
of final engineering plans for the project.
As a courtesy Mr. Tim Home is contact the McDowell family regarding the change in street name
to Harris Road. We feel that the City should also provide official notification of the name change
as well
I feel that this letter, together with the changes made on the revised preliminary plat and plans
attached, address the concerns expressed by City Staff on this project. Please feel free to call me if
there are any additional comments.
As always, I appreciate your assistance in this matter.
