Subject: Eavironmental Assessment for the Proposed Route 67 Improvement
Project (PM 16.4/17.7, 11209-194751, Safety Related Improvements)
Dear Jack:
lbank, you for your letter of January 27, 1986 which confirmed the results
of a. joint meeting, on. January 23, 1986, between City of Poway officials
:and Caltrans management in. regard to the subject matter.
The City of Poway appreciated the opportunity to review and comment upon the
Environmental Initial Study, and proposed Negative Declaration prepared by
your staff for the project in question. We: understand that the timing of
_ the proposed nprovement project is very important, and we acknowledge the
extension;of the public review period for the City's response to the
environmental documents
As you know, the: majority of the subject project is located within the City
of Poway and also traverses a parcel of public land which is presently
controlled by the Bureau of Land Management (BIM) In. August of 1983 the
City of`Poway entered into a five-year lease program with the BIM, pursuant
to the provisions of the Recreation and Public Purposes Act. The lease
comprises five, large parcels totaling 1,.877 acres of territory located
adjacent to the City's easterly corporate boundary. The parcel which is
traversed by the proposed highway project is included in the lease area, and
is therefore subject to the terms and conditions of the lease agreement.
In, accordance with the lease agreement, the City of Poway is committed to
develop and manage an interconnecting system of hiking and equestrian trails
over tha five BEM parcels. This system, which. consists of approximately
twenty-two miles of existing and planned trails, will ultimately tie: into
the remainder of the: City's comprehensive trail systema
The, Bureau of Land Management is favorably impressed with the City's
progress to date. About eight miles of the planned BLM trail system is in
place at the present time. Because of this progress, the BIM has authorized
the. City to initiate annexation proceedings for the 1 320 acres of public
domain which lies contiguous*to Poway in the unincorporated territory of San
Diego County. The subject annexation proceedings are presently under way,
and when complete, the City will receive title to the lands.

The City of Poway has determined that the proposed highway improvement
project would have potential adverse: effects on the environment unless the
impacts are ignificantly reduced through the implementation of appropriate
mitigation measures.
The following paragraphs discuss the potential impacts of the project.
Following the description of each potential impact are the specific
mitigation measures which would reduce the associated inpact.to a level of
insignificance. As a result of the above-mentioned January 23, 1986 joint
meeting, the City of Poway and Caltrans are in agreement that the following
mitigation measures., when incorporated into the environmental documents,
will support the issuance of a Negative Declaration of environmental impact
for the subject project. It should be noted that the Poway City Council has;
endorsed these mitigation measures.
:1
Impact - Visual Quality.
The proposed project would potentially impact approximately 21.5 acres of
established, densely vegetated slopes. r1iis is due to the westerly acquisi-
tion of right-of-sway neededfor the proposed separate southbound two-lane
roadway on split alignment. As a result of the proposed split alignment,
�
massive fill. slopes would be created. and about 130 large: mature coast live
oak trees, including other mature shrub species, would be directly impacted
by construction. .9he mitigation measures suggested in. the. Initial, Study,
the replanting of 600 liner size (one-gallon) oaks, would, not adequately
mitigate the visual impacts associated with the massive fill slopes. This
measure. would result in about 28 liner size oaks per acre: of impacted. area,
which would not significantly reduce the impact. In addition, the estab-
7:shment and survival of plant and tree species in harsh environments found
on newly graded slopes requires the application of adequate irrigation
during the plant: establishment period.
Mitigation Measures
a. In order, to reduce the impacts to visual quality, Caltrans will: in-
crease the: size: of oak tree replacement from 600 liner size oaks to the
following: 10 percent (of the 600) will be of twenty-four inch box
size; 20 percent will be of fifteen. gallon. size, 15 percent will be of
five gallon size; and the remaining 55 percent will be of one gallon'
size.. To reduce the overall. cost to Caltrans for the: larger size oak
trees, the City of Poway, prior to construction, will provide assis-
tance in harvesting, bagging,and storing as many larger trees as
possible that would otherwise be lost during construction. The number
and sizes of oak trees that can be saved by this assistance program will
reduce the numbers and sizes Caltrans has agreed to provide. Other
mitigation measures, as identified in the environmental documents, will
include hydroseedi.ng and supplemental planting of native species such as
<< toyon, lakeside lilac: and laurel sumac.

b. In order to provide for the establishment and survival of all
replanted vegetation types mentioned. above Caltrans will design: and
installan adequate irrigation system which will provide permanent
irrigation for a minim nn of three seasons, or until the vegetation
is established and can reasonably survive under normal climatic
conditions.
Impact. Existing and Planned Trail System
As mentioned previously, the City of Poway is committed. to develop and
mage a system of trails over theBLM parcels. At the present time, the
five-Tadle Mount Woodson trailexists between Lake Poway and Route 67, on
the northwest side of the highway project. Approximately one milei south of
the project limits, on the east side of Route. 67 next to Ellie Lane,exists
a newlyconstructed equestrian staging area and a. planned trail which
continues eastward towards Iron Mountain located on a separate BLM parcel.
This trail is ten miles in length and the first two miles are constructed,
Pursuant to the agreement with the BIM, the City must connect the Mount
Woodson trail wJLt the Iron'. Mountain trails and in. order to achieve this
connection, an existing trail must be extended southerly and Route 67 must
be crossed..
Mitigation Measures
II a.
In order to extend the Mount TrToodson trail southerly from its current
terminus, Caltrans will. provide within the proposed right -of -sway, and
at the toe of the. slope, a continuous graded trail (tread.width)
designed in accordance with thei City's adopted Trail Standards and
Specifications. This trail tread will extend from the existing Mount
Woodson trail terminus to the southerly project. limits. The City of
Poway will conplete and maintain the trail once the highway project, is
in place.
In the event: Caltrans plans for future highway improvements south of
the current project to the vicinity of Ellie Lane, the City would
prefer to incorporate trail improvements within the right-of-way, if
possible.
b. Both the City and Caltrans recognize that an at -grade crossing of the
highway at Ellie Lane would be extremely undesirable due to traffic and
safety factors. However, both agencies agree that an undercrossing.at
or near the Ellie Lane staging area would be the most advantageous and
feasible method of providing a highway crossing for hikers and riders.
In order to provide the necessary mitigation, Caltrans will design. and

construct a pedestrian/equestrian undercrossing at a suitable location
in the vicinity of Ellie bane. This undercrossing will be designed. to
accommodate both hikers and. equestrians as specified by City standards.
The crossing, under the existing roadway, Would Provide for the connec-
tion of the. trail system on either side: of Route 6T in a safe and
logical manner. Caltrans agrees to commit funds, from a. future small -
project source, at 75 percent of the: cost of the subject structure and
to provide ongoing maintenance to the structure. The City of Poway
agrees to provide. the balance of the cost of the subject structure, at
25 percentofthe total cost. The City further, agrees to provide
Tate for the trail -tread, portion of the. undercrossing structure.
In conclusion, the City of Poway believes that the above-mntioned potential
impacts which would occur as a result of the project would be I reduced toy a.
level ' of insignificance through the implementation of the mitigationmeas-
uses discussed above. Veen these measuresare incorporated into the. pro-
posed project, the ; City is of the opinion that the project would. not result
in an impact on the recreational program established between the City of
Poway and the Bureau of` Land Management Therefore, there would be no 4(f)
involvement as define by State Law. In addition,these mitigation measures
N
wvuld.be consistent with and. in support of the BIM,s intent to provide con-
,.'
tinning recreational opportunities on its public lands. Once the final
roadway, revegetat on, trail,. and undercrossing plans are available, the.
City would appreciate the opportunity to review and comrent on them.
