OWNER: Spectra Land, L.P.
APPLICANT: Adams Engineering
PROPERTY SITUATION: The property is located at 330 through 360 W. Bob Jones Road
LEGAL DESCRIPTION: Tracts 3, 4, 4A, & 413, R.D. Price Survey, Abstract No. 992; and Tract 11, A.
Robinson Survey, Abstract No. 1131
LAND USE CATEGORY: Low Density Residential with a Rural Conservation overlay designation.
CURRENT ZONING: "RE" Single Family Residential Estate District and "AG" Agricultural District
PROPOSED ZONING: "SF -IA" Single Family Residential District
HISTORY: There is no development history on this property.
Land Use Plan Recommendations
Although the proposed development is consistent with the Low Density Residential land use designation,
rural conservation subdivision zoning should be considered instead of SF -1A to protect and preserve the
existing environmental features on the site.
Mobility Plan & Trail Plan Recommendations
• Maximize pedestrian connectivity from neighborhoods to Lake Grapevine and Bob Jones Park.
o A sidewalk or trail is recommended to provide access to the adjacent Corps of Engineers
property.

Environmental Resource Protection Recommendations
Case No. Attachment A
ZA06 -030 Page 1
• Protect the city's remaining agricultural /equestrian and environmental areas in the North Side Plan
Area by requiring residential development to occur in a manner that has the minimum impact on
these resources.
o Rural conservation subdivision zoning is recommended in this area to minimize impact
on the natural resources.
• Protect and enhance critical environmental and natural features, with particular emphasis on trees
and floodplains. Allow floodplains, wetlands, and streams to remain in a natural state and
preserve a tree buffer around these features. Specifically, the Environmental Resource
Protection Map identifies priority areas for protection as shown below:

o The priority areas for protection are not addressed in the proposed development. An
alternative lot layout should be considered to preserve the natural features of the site to
the maximum extent feasible.
TRANSPORTATION
ASSESSMENT: Master Thoroughfare Plan
The Master Thoroughfare Plan recommends N. White Chapel and T.W. King
Road adjacent to the proposed subdivision to be undivided, 2 -lane collector
roadways with 70 feet of right -of -way. Right -of -way is being dedicated
accordingly.
Existinm Area Road Network and Conditions
The proposed subdivision will have one (1) street intersecting with north side
of W. Bob Jones Road, between N. White Chapel Boulevard and T.W. King
Road. W. Bob Jones Road is designated and is existing as 2 lane undivided
collector street. The MTP calls for a minimum 60 feet of ROW width which
is being provided as part of this development.
Bob Jones Road, N. White Chapel Boulevard and T.W. King Road are
currently 2 -lane, undivided roadways. The capacity of the existing roadway
network is approximately 8,400 vehicle trips per day. Under this condition,

ZA06 -030 Page 2
each roadway would be considered to operate under a level of service `D'.
This development is not expected to warrant expansion of the existing
roadway networks.

WATER & SEWER: Water An 8 inch water line will be extended approximately 500 feet along the
north boundary of W, Bob Jones Road from an existing 12 inch water line in
North White Boulevard to the boundary of the property. An 8 inch water line
will be extended into the subdivision along proposed Saddleback Lane. An 8
inch line will be looped back to the 12 inch line in N. White Chapel Boulevard
about 1,200 feet into the subdivision. The 8 inch line will extend another
1000 feet as a dead end line with a fire hydrant at the terminus.
Sanitary Sewer Lots will be served by an 8 inch sanitary sewer line which
gravity flow to a proposed lift station at the mid eastern boundary of the
subdivision and N. White Chapel Boulevard. A 4 inch sanitary sewer force
main will be extended from the lift station approximately 2,236 feet to the
interaction of King Ranch Road and N. White Chapel.
DRAINAGE ANALYSIS: The southern 2 /3 rd of the property currently drains to the east back toward N.
White Chapel Boulevard. The remaining northern 1 /3 rd drains to the north
into the Corp of Engineers property for Grapevine Lake and into the privately
owned property to the west. Approximately '/2 or more of the proposed
drainage, primarily divided between the north and south halves of the, will be
collected in the street, piped through an underground storm sewer and
Case No. Attachment A
ZA06 -030 Page 3
discharged into two detention areas located along the east and west
boundaries.
TREE PRESERVATION: The submitted plans show no indications of preserving any of the existing
trees or natural aspects of the property except for on the individual residential
lots. The topography of the densely wooded areas of the property is extremely
varied. Creeks and ravines exist within the north portion ofthe property which
encompasses Lots 14 — 21, Block A. Although the lots are more than one (1)
acre, the construction of large homes would cause the removal of "Quality"
trees outside of the allowable tree removal areas and definite changes in the
properties topography.
The proposed Preliminary Plat shows a 50' Tree Preservation
Buffer/Easement to surround most all of the property but there are almost no
trees existing within 50' of the north and south boundary lines of Lots 1— 10,
and 22 — 34. The only densely wooded areas within the proposed 50' Tree
Preservation Zone is on Lots 11 — 21.
The proposed Tree Preservation Buffer/Easements are proposed as a part of
individual lots. Once a lot is homesteaded the property owner is responsible
for maintenance and health of the existing trees and vegetation on the lot.
Individual homeowners are not generally aware that such thing as a Tree
Preservation Zone exists on their property and enforcement of regulations that
pertain to the Tree Preservation Zones cannot not be properly enforced.
Non - Disturbance Areas / Tree Preservation Easement: If the Applicant
designates a nearly wooded area as a non - disturbance zone in which no
construction will occur there should be no easements located within the area,
no construction of any type shall occur within the area, the area is intended to
remain natural in perpetuity, and a single incidence removal ofunderbrush and
vines is allowed subject to the requirements of Section 6.3 of the Ordinance
585 -B.
There are easements either existing or proposed within all of the proposed 50'
Tree Preservation Buffer/Easements
P &Z ACTION: April 6, 2006; Approved to table until the April 20, 2006 meeting.
April 20, 2006; Approved to table until the May 4, 2006 meeting.
May 4, 2006; Approved (5 -1) subject to Revised Plat Review SummaryNo. 2
dated April 28, 2006, showing the building pads as presented and granting a
variance to the subdivision ordinance requirement for 2 planned points of
access and the staff recommendation for a street stub into the west boundary.

CITY STAFF HAS REVIEWED THE ABOVE REFERENCED PROJECT RECEIVED BY THE CITY ON 03/20/06 AND WE
OFFER THE FOLLOWING STIPULATIONS. THESE STIPULATIONS ARE HEREBY MADE CONDITIONS OF PLAT
APPROVAL UNLESS SPECIFICALLY AMENDED BY THE CITY COUNCIL. IF YOU HAVE ANY QUESTIONS ORNEED
FURTHER CLARIFICATION, PLEASE CONTACT DENNIS KILLOUGH AT (817) 748 -8072.
The following changes are needed with regard to easements:
Provide easements for water, sewer and /or drainage in compliance with approved
construction plans.
b. Although the Subdivision Ordinance requires general utility easements along the perimeter
boundary of the property, staff recommends that easements be provided only where
absolutely required for adequate distribution and extension of public utilities for the
purpose of tree preservation. Staff further recommends that utilities be provided at the
minimum width along the perimeter of the streets to further add in tree preservation.
Staff recommends providing minimum 10' wide pedestrian/equestrian access easement
from Saddleback Lane to the northwest corner of Lot 16 for future access to the Corp
property and from Saddleback Lane to N. White Chapel Boulevard along the north line of
Lot 24. The MPP calls for a minimum 8' multi -use trail in this proximity. Staff
recommends that the applicant coordinate with the City's Parks Department and Park
Board.
2. The following changes are needed regarding the proposed lotting:
All lots must comply with the underlying zoning district for the property. As currently
proposed this property does not comply the majority of the underlying "AG" zoning nor is
the entire boundary of the property appropriately zoned for this plat proposal. As
proposed, approval of this plat is subject to receiving approval of an appropriate change
of zoning. A zoning change is being processed concurrently.
Case No.
ZA06 -030

Page 1
b. Lot area shown for lots 1 and 32 does not appear to be correct. The Landscape
easements should be included in the lot boundary. Also, the minimum 40' building
setback line can be measured from the ROW line on the corner lots.
3. The following changes are needed regarding Right -of -Way dedications and /or interior street
geometry:
a. Provide a minimum of two planned points of access. Place a note on the plat regarding
the commitment to install fire sprinkler systems in all homes to comply with minimum
requirements of the Fire code. (Variance requested in lieu of providing fire sprinkler
systems) (5.01 -C)
b. The subdivision ordinance recommends a maximum length of 1000' and a maximum
number of 20 lots on a cul -de -sac, but provides that mitigating conditions such as
topography and configuration of the tract may vary these requirements. Justification must
be provided for the current proposal. At a minimum all emergency access and
management standards must be complied with in accordance with Department of Public
safety policies. . (Variance requested in lieu of providing fire sprinkler systems)
C. Provide sufficient street stubs into adjacent property. Street stubs are generally
recommended at maximum 1000' intervals along boundaries of undeveloped or under
developed properties. (No. 483 - 5.03 -K -1) (Variance Requested)
The following should be informational comments only
* Plat vacations must be submitted approved and filed of record for portion of the property already
platted prior to recording the final plat.
* A Final Plat approval and a Developers Agreement is required prior to construction of any public
infrastructure. The Developer's Agreement for this addition should consider streets, drainage, park
dedication requirements and fees, off -site sewer extensions, off -site drainage and utility easements and
impact fees.
* As part of any final plat, two intervisible boundary corners of the site must be georeferenced by state
plane coordinates in accordance with section 8.03(B) of the Subdivision Ordinance No. 483 upon
submittal of the final plat, and, prior to acceptance of the subdivision by the City, a digital computer
file of the subdivision must be provided in accordance with Section 8.04 of Ordinance No. 483.
