HISTORY:
The property is part of a former 766-acre tract which included land
the City purchased in 1982 for parks and municipal buildings. In
the purchase contract the City agreed not to change the subdivision
regulations applicable at the time to the balance of the 766 acres.
A change of zoning on the portion to be platted as Copper Stone
from MF-2 to SF-9 and SF-12 received approval in June of 1992,
with the ordinance taking effect in June of 1993.
Item 9
A preliminary plat for Copper Stone received approval in June of
1992, and on June 8, 1993, City Council approved a one-year
extension. The final plat received approval in March of 1994, but
was never recorded. Consequently, the final plat became null and
void on September 8, 1994. However, because a final plat was
submitted prior to June 8, 1994, by current regulation the
preliminary plat is still valid.
TRANSPORTATION:
Parkway Boulevard is a four-lane divided street (C4D) contained
within a right-of-way which varies in width from 80 to 85 feet.
SURROUNDING LAND USE & ZONING:

Vacant; SF-7 and PD-SF 7 zoning
COMPREHENSIVE PLAN:
The 1987 Comprehensive Plan showed high-density
residential use as the most appropriate for this area. The
current revision of the plan will show the area as more
suitable for lower density residential uses.
DISCUSSION:
The applicant has made one major change to Copper Stone since the approval of the final plat
in 1994. The number of entrances to the portion south of Parkway Boulevard is now one,
instead of the previous two, and the streets beyond that entrance are to be private. In addition,
the applicant proposes to change the names of some of the streets.
According to the 1982 Contract of Sale between the City and Parks of Coppell loint Venture II,
both parties agreed that the City Council's continuing proper interpretation of the subdivision
ordinance with respect to the 766-acres owned by Parks of Coppell JV II shall include the
following:
"filing of a final plat for an area shall constitute acceptance by the City of the
streets for maintenance within such areas".
Since maintenance of private facilities would be a misuse of public funds, clearly the City can
accept only public streets for maintenance.
While the City is obligated to approve the final plat of Copper Stone under the terms of the
Subdivision Ordinance in existence in 1982, the City has no obligation to waive alley
requirements in the SF-9 District or cul-de-sac length requirements, as it did when it approved
the previous Final Plat, and no obligation to accept park dedication.
Item 9
Amhurst, as a street name, closely resembles an existing street named Elmhurst. Also, the
previous City Council required that one of the street names be Turkey Knob.
RECOMMENDATION:
Staff is on record in opposition to private streets within single-family residential subdivisions.
Like burglar bars, private streets provide the illusion of restricting access, but they do not keep
resourceful burglars out, nor do they provide greater safety and security per se. Burglar bars
trap occupants, sometimes with deadly consequences. Private streets impede and retard response
time of paramedics, firemen and the police to life-threatening emergencies. Staff considers the
protection of human life as more important than the protection of property and believes that the
unrestricted access of emergency vehicles is an important component of public safety.
Staff recommends that the one entrance to the south side of Copper Stone be permitted with its
median, median column, entry columns, walls and wrought-iron fences, but that the card-
operated gates not be permitted and that the City accept maintenance of the streets as public
streets in accordance with its 1982 agreement.
Staff recommends changing the street name currently designated Amhurst, but concurs in the
other street name proposals. Staff further recommends acceptance of park dedication adjacent
to Denton Creek for the sole purpose of providing a location for the hike-and-bike trail shown
on the City's trail plan. If the developer wants to provide a 20'-wide easement for the trail
instead, staff will recommend acceptance of that in lieu of the park dedication.
With these stipulations, staff concurs in the waiver of alley and cul-de-sac length requirements.
Without these stipulations, staff believes that the provisions of the 1982 Contract of Sale will
no longer be valid and that the current provisions of the Subdivision Ordinance will apply.
Therefore, staff recommends approval of the Final Plat with the stipulations previously stated
and subject to compliance with Engineering Department requirements as follows:
1. Provision of sight visibility triangles as all street intersections.
Provision of a 20'-wide utility easement for the proposed water line connection to
Parkway Boulevard from the west cul-de-sac of Amherst Way (as currently named).
Provision of a detail of the proposed median on Amherst Way and a note that it is to be
maintained by the Homeowners Association.
Clarification as to maintenance of any proposed retaining wall along the rear of the lots
on the north edge of the subdivision.
5. Provide a 90 o intersection of Copperstone Trail with Parkway Boulevard.
6. Provide a note referencing the lots to be dedicated to the City.
Item 9
e
Provide permanent erosion protection for Amherst Lane between Lot 7 Block D and Lot
23 Block E and evaluate the need for erosion protection adjacent to Lots 10-23 Block E
and Lot 7 Block D.
Relocate the sanitary sewer off of Lots 12-16 Block A or provide a rear building line
which reserves sufficient space for the construction of swimming pools between the rear
building line and the sanitary sewer easement.
