F, TRAFFIC; IMPACTS
His and current t affit studies indicates that each
residence in the project area would be expected to gener.atP from
7-10 trips per 'day. For this analysis, the greater, or "Worst
case" figure is employed, Actual project ADT may be somewhat
lower due to to relatively long (10^13 miles) distance to major
service centers in the Chico urban area; poor project roads and
proximity of Forest Ranch.
The estimated 15 dwelling units now r,n the ground would
generate 150 AD`S: At full buildout in 1995, 107 residences v6uld

Highway Corridor - Traffic Hazards;, The generation of 1;070
ADT will. add at least this number of turning moventents—ingress

occasionally traveled byybicyclists, particularly during the harm
months, the need will increase for them to exercise reasonable
caution to insure their own safety.

over most of the roate `between. Chico and 'Forest hunch. Each
highway lane is 12 feet vride, though the width of the road
shoulder may vary from iriore than five feet to three.; feet near
canyon rims.-
The highway in the -vicinity of Teti Mile Houae Road has
1;x,-4% grades ascending in both directions from the road
connection, A curb borders the road shoulder along the west side
of the 'highway. Shoulder width'ranges ;from 3-4 fey+t along this
Election. A broad curve begins approximately 500 feet south of
the rod connection;
The highway is generally level in the vicinity of La Castana
Drive, though a slight ascending grade exists north of the road
connection. A cut bank is located along the east side of the
highway, approximately .200 feet north of the juncture. !be Vidth
of the shoulder averages 3-5 feet, and is border. ed by a. curb
The Wghway ascends a steep grade '(4-6%) north of Altati.na

A cut bank exists on the ~ast side of the highway approximately
1,000 feet north of the jLncture, The road shoulder averages 3-5

The: above conditions would marginally increase traffic

111. DISCUSSION OF ENVIRONMENTAL EVALUATION
•'
This project is an application for three additional public road
cona.sct;ions to State Mighway Route 32, northeast of Chico. The
proposed road connect .ors are Ten Mile House Road, La Castana
Drive and Altatina Drive. The general'project site, identified as
Study Area X12 (see attached map), is located approximately 10
miles northeast of Chico in the Forest Ranch area. The project
bov.ndaries occupy portions of�Sections 25-, 30, 31', 35 and 36,
Townhip 23 North, Range 2 East M.D.S. & M.
The topography of the project areas are generally less than 10t
slope on the ridge tops and 30% to 60% or more toward Little
Chico Creek canyon. Little Chico Creek lies about 3/4 of a mile
to theeast of the proposed road connections.
Natural vegetation in the study area is typically chaparral.
Common plank species include chamise toyon, 'mranzanita;
California lilac (ceanothus), scrub oak, blue oak, digger pine
and various herbs and grasses. The study area is in, the U'ppe'r
Sonoran Life 'Lone, which includes a great diversity of wildlife.
Wildlife species include skunk, coyote, California ground
squirrel, deer, quail, hawks, lizards (fence, sllightor, etc.),
snakes (racer, garter, king, etc.), various birds, insects and
other species.
The present land rises in the project ;areas are residential on
•
lots averaging 5 to 40 acres in size and open chaparral land.
Land use in the immediate
vicinity of the proposed road
connections primarily consists of open acreage$ with fewer than
10 residences sparsely located throughout this area in -proximity
to Highway 32. Another 7 to 8 residences occupy the remaining
parcels in the study area.

The study site consisted of the area surrounding the three road entrances and.
a small portion of a frontage road rl.ong a twO.mile portion of Highway 32
approximately 10 miles northeast of Chico: T e three roads all enter the
highway from the east and are named Alta Tina, La "castana and 10 -,mile House Trail.
The frontage road that was surveyed connects the latter two road entrances. In
this area Highway 32 traverses a rdgetothat separate s Little and Big `Chico
Creeks: The ridge is underlain by the Tuscan geologic formation and no special
SOU types (e.g. Serpentine) or geology (e.g. basalt outcrops) are present
that would influence the vegetation and possibly increase �:ho probablity of
finding any rare or uncommon species.

Dear Mn Nelson,
Alt /our recluest on April 8, 1983 1 conducted an archaeological
survey of three access junctions along Highway 32 The three
junctions are located along a one milesection of Highway 32
approximately four miles to the south of Forest Ranch .in
Butte County. The proposed connections are identified ast
#1"Ten`Mile House Road; #2 -Smith -Shears proposed access;
#3-Altatina Drive. All of the proposed connections are
located along the east side of Highway 32. Two; of the access
points are located at eXi8tirLg intersections, #1 at Ten Mile
House Road and # 3 at Altatirta DrIve. The #2 access point
is located near the intersection of La Castana Drive aril
Highway 32. The proposed ac Gess points are located as follows t
#1 to the west of the approximate center of the section ;line
between Sections 35 & 36, T. 23 N.0 R a 2 E-0 #2 in. the NWI of

Prior to conducting a survey of these areas I consulted the
archaeological site record files located at. California State
Un `vers-ity, Chico to determine if ,any previously recorded
archaeological sites had b�eeft recorded within or adjacent to
the project areas. No previously recorded' archaeological
sites
had been recorded within these areaso Ohly two
archaeological sites had`heen 'recorded along the ridge "top
between Forest Ranch, and Chico. Whose consisted of one historic
site and one prehistoric'�iitej located approximately 2 miles
to thei
north. The hsto±�Io site is Fourteen Mil Hooso; an
�
historic 'wagon stop along the old Humboldt Road; that date's to
the mid -i8008, The, prehiotor'ic site consisted of two shallow
bedrock mortars adjacent to a spring.

Dear Members of the Board:
This involves the mutual. problems our regective agencies face in dealing with
c I
the subdivvision of properties, the current growth in rurally located industry;
expanding populations; and thQ-resultant adverse effects created by the
generation of increased tt ffic tvwlames impacting upon State and County roads
and facilities. It is hoped that through cooperative efforts our two flections
can unite in a chtnmon cause to best benefit the taxpayers; the road users,
county residents and the agencies ,involved.
Our major point of concern with the county's existing operations lies in its
(the county's) delineation of environmental impact application; interpretation
and implementation in cases where State highways are an into` a1 factor. The
conflict between the State's interpretation and that of the c�o'unty's involves
the Limits and intent given the statement. Your former County Counsel
Dan Blackstock has offered an opinion 'that county appz�oval of subdivision plans
adjacent State higWtys need only address the issues of ingress/egress to a
Limit abutting the State's ri&t of wLI line.
A case in point are ,hose properties a=long Route 32 in the area betvteen 10 Mile
House and 'Forest Ranch which have been the subject of discission for the 'past;
five years- Subdivis,lon plans have been approved in these areas which call :for ,
interior subdivision development of 60' wide road easoments that are allowed to.
terminate 91Ain8t the State's t1no aocesoh r ght of way limits. From that lint
to the actual h�,ghway traveled Vey, the devel.rpers and future residentse ,
then perrd 'ted to utilise -the existing 20'=wide road approaches to service
their praperties. Caltrans has strong feelings on the shortsi&tedness and
impractica7.ity of ali wing such situations to occur.
Tile 2O' �-fide access points the State constructed (a7:ong niahwoy `32) in the
early 19601s were not designed with -their presently proposed -typo of usage in
minds At the t
ime of initial construction most of the access points were
