features such as windows, doors, patios, roof lines, and walkv✓' s, etc,
Correct plant im1l,erial solect:ion is critical for safety precautions ots

Term Productivity:
Short 'term ''uses` of the environment will contribute 'to ;
ti
the depletion of locally available building materials and will
create local disruptions as , described, during construction„"ur-
rounding land uses precludeDth.e benefits of'long.term agricul-

Introduction
S
Eastwood Oaks is a proposed devei�opment of 131 condo-
minium `units on ,1A.3 acres in ari unincorporated area `of'Butte
Cowity adjacent to Chico, Califon, iia. The site is an irregularly
shaped paibel with access proposed to the ehi"sting streets do
on Lassen Avenue at Goodman Avepte, on Tom, Polk Avenue at Panama
t..`� Avenue, . and El. Verano Way' at, El` Paso Way. The third access
point is being considered as an emergency access only.

This report presents'an an r, _y ects
of this development on traffic coedits ons in the virin� nity, , and �
presents estimates of the effects of added traffic on noise and
air pollutant levels. The development's internal, streets are
reviewed to ensure they can adequately servethe `traff is needs
of the development. ApproPtiato-traffic engineeringmeasures
are identified to minimize traffic impacts.

Traffic Counts and Trite Assignment Ri
Before the "afte•r-project traffic flows can be estimated,
a picture of traffic conditions'befgte development occurs is
necessary. Current traffic counts were obtained from Mit--te
County Public Works, CALTIRANS District 03 in. Marysville,
California, and the City of Chico. Those counts were utilized
to prepare the data presented in Figure 1. Counts shown are
intended to represent average 24-hour weekday traffic for the,
yeah 1977.
obtained d were collected by recording ,-
de-Vides which tabulate traffic flows by the hour. From these
A few o� the counts ob
recorded counts it was determined that,,,, ton per cent of the 24-
hour two-way traffic occurs during. the peak hour in the predom-,
inapt travel: direction. This peat -hour percentage was used iii
estimating the 24-hour capacities, of the streets to be ,.used 'by"
development traffic.
Once the direotionaY`,distribution of the developfient's
traffic is estimated; that�NL"°'3ffic may be assigned to specific
routes based on the shortest"-Eravel time. The current 'traffic �.'.
flows Wete thus `increased by assigning to the 6xist'ing street
system the traffic to be
y generated by the development.
Tato access options ` were'' analy�ed: The first option
assumes three points of direct access to Eastwood 06ks, �hclttd- '
ing an access on Lass :en Avenue+ an access at Tom Polk Av6nue
and an esti matedctrafficEaso Way at E1 Verano Way. The resulting
1) volumes for this access conditioA are shown
in Figure 2 The second option assumes only two points of access
to the project, eliminating the access, to E1 Paso Way. The
estimated traffic volumes with the E1 Paso Way access �-�ose :..>to "
