RE:
dP No. 88009; Parks of Coppell;
Heartz Road; Sanitary Sewer Study; Coppell, Texas
Dear Jay:
Pursuant to the City of Coppell's review comments for the Heartz
Road preliminary plat, we have prepared a study of the sanitary
sewer in Heartz Road from Sandy bake Road to Parkway Boulevard.
The purpose of our study was to evaluate sanitary sewer flows in
Heartz Road with fully developed conditions of development in the
service area based on existing land uses in developed areas and
current zoning in undeveloped areas. These discharges were then
compared to capacities in the existing eight-inch sewer line. If
existing capacities are deficient, we determined sewer pipe sizes
necessary to obtain the required capacity to adequately serve the
area upon full development.
Enclosed is a table showing computed design flow and pipe
capacity determined between manholes in the existing sanitary
sewer line in Heartz Road. Also shown is the additional sewer
pipe needed to provide total capacity in excess of the design
flow, where required. It is assumed that a parallel pipe will be
constructed on the same slope as the existing pipe.. Manhole
locations are shown on the. service area exhibit also enclosed.
The design flow at each sanitary sewer manhole (SSMH) on the
existing sewer line north of Sandy Lake Road was established
based upon "Ultimate Development" conditions using Harmon's
Formula for Peak Flow with an additional infiltration factor of
750 gpd/ac. This design method is used by the City of Fort
Worth. The infiltration factor is adopted from methods used by
the City of Plans.
The results of our study indicate that the two upstream sections
of the existing sewer line in proposed Heartz Road between SSHH#6
and SSHH#4 are adequate to serve the upstream service area.
However, the remainder of the existing system, approximately 1930
L.F., from SSMH#4 to Parkway Boulevard, is inadequate and will
require the construction of a parallel line. The size and
lengths of additional pipe required for ultimate development of
the service area are listed in the table. A single pipe
equivalent has also been calculated for each section in case you

elect to remove the inadequate sections and install a single
sanitary sewer line having the required flow capacity.
We have also investigated whether the existing sanitary sewer in
Heartz Road is sufficiently deep to permit service laterals to
serve your property on the east side of the channel that
parallels Heartz Road without requiring aerial crossings. Using
surveyed channel bottom elevations and sewer pipe flow line
elevations obtained at existing manholes, it appears that the
existing sewer pipe is slightly higher than the adjacent channel
bottom. Therefore, lateral pipes crossing the channel will be
above the existing channel bottom.
We will proceed with an evaluation of the sanitary sewer
extending north across the 27.5 acre tract north of Parkway
Boulevard. This sewer receives flow from the Heartz Road
sanitary sewer and sewers in Parkway Boulevard.
We will submit this evaluation of the Heartz Road Sanitary Sewer
to the City of Coppell following your authorization. If you have
any questions or require any additional information, please do
not hesitate to call.

Re: Ownership gap/Abandoned Heartz Rd.
Coppell, Texas
Dear Jay:
As a follow-up to our telephone conversation, I have been unable to
locate any "formal abandonment" action pertaining the portion of
Heartz Road north of Sandy Lake Road.
I contacted the City Secretary, Dorothy Timmons, (214/462-0022), who
stated that there is no abandonment ordinance on record regarding this
portion of Heartz Road.
I contacted a Mr. King in the Public Works department of Dallas County.
He could find no record of abandonment by the County. His number is
214/653-7151.
It is possible that this road was established by use with no formal
dedication. Your attorney might want to investigate this matter further.
With respect to the 5 acre tract east of the proposed Heartz Road, I
have enclosed a copy of a deed from a MARK PERKINS to JOAN SOKORA BLAKE,
JACQUIE STUBBLEFIELD, MARY BETH SHIELDS and TIM SOKORA. According to
the City tax records, tax bills are sent to MARY BETH SOKORA SHIELDS,
145 Centennial Dr., Lewisville, Texas, 75067. The Lewisville tele-
phone directory lists J.W. Shields, Jr. at that address, telephone
number 214/436-5708.
Let me know if I can be of further assistance in these matters.
