Date: March 3 rd , 2017 L&M Project: 1256‐09 Attention: Tristin Deveau Planner Reference: North Nechako Rezoning RZ100547 Traffic Analysis BACKGROUND Fair Value Homes are proposing to rezone the properties at 846, 868 and 930 North Nechako Road from AR3 (Rural Residential) to RT3 (Residential Cluster) to allow for the development of a 27 unit strata complex. A conceptual layout for the development is shown in the attached drawing RZ4. TRIP GENERATION Trip generation rates for the site were based upon the published rates identified in the Institute of Traffic Engineers (ITE) Trip Generation Rates 8 th Edition. The rates were based upon those for a single family detached housing (ITE Code 210). The conceptual layout shown on Drawing RZ4 indicates 27 units. The maximum units allowed for the RT3 zone is 25 units per hectare or 53 units. The trip generation for both scenarios is shown in Tables 1 and 2.

Fair Value Homes are proposing to rezone the properties at 846, 868 and 930 North Nechako Road from AR3 (Rural Residential) to RT3 (Residential Cluster) to allow for the development of a 27 unit strata complex. A conceptual layout for the development is shown in the attached drawing RZ4.
TRIP GENERATION
Trip generation rates for the site were based upon the published rates identified in the Institute of Traffic Engineers (ITE) Trip Generation Rates 8th Edition. The rates were based upon those for a single family detached housing (ITE Code 210). The conceptual layout shown on Drawing RZ4 indicates 27 units. The maximum units allowed for the RT3 zone is 25 units per hectare or 53 units. The trip generation for both scenarios is shown in Tables 1 and 2.

TRIP DISTRIBUTION
Given the location of the development the primary direction of travel will be to the south
towards the city centre. In the am peak some traffic may head north towards Edgewood
elementary to drop children off at the school. The trip distribution and resulting development
traffic is shown in Figure 1 (attached) for both scenarios.
ACCESS SIGHT LINES
The proposed access is situated near the northern corner of the property to maximize the sight
lines to the south where North Nechako Road curves to the east. The speed limit on North
Nechako Road is 50 Km/h and transitions to 60 Km/h just north of the property. When
considering available sight distances there are three distances to consider. As defined in the
Transportation Association of Canada (TAC) Geometric Design Guide for Canadian Roads.
1. Safe Stopping Sight Distance – is the distance required to safely stop a vehicle taking
into account perception and reaction time, and the required braking distance.
2. Decision Sight Distance – is the distance required to stop when the driver must make
complex decisions, or information is difficult to find or unusual manoeuvers are
required. Examples where decision sight distances are warranted are at complex
interchanges of intersections, or where significant changes to the roadway cross section
are made. This criterion does not apply to this driveway access.
3. Turning Sight Distance – is the distance required to allow a vehicle turning from a stop
condition into a vehicle stream and accelerate while not slowing the vehicle on the main
road to less than 85% of the design speed and maintaining a 2 second gap between the
vehicles. There are four types of turning sight distances to consider:
Fair Value Homes March 3rd, 2017 Traffic analysis Project Number: 1256‐09
L&M Engineering Limited Page | 3
I. Crossing Sight Distance;
II. Sight distance for a vehicle turning left with a vehicle approaching from the left;
III. Sight distance for a vehicle turning right with a vehicle approaching from the left;
and
IV. Sight distance for a vehicle turning left with a vehicle approaching from the right.
Conditions III and IV are the same distance and are considerably more stringent than conditions
I and II. The required sight distances are shown in TAC Figure 2.3.3.4.
To determine the available sight line distances an eye height of 1.05m and an object height of
0.6m (representing an approaching vehicles headlight) was utilized. The simulated driver was
stationed at the proposed driveway access and the available site distances with the 0.6m object
height were measured (by GPS Survey) to both the south and the north. The results and the
minimum required distances are summarized in Table 3.

Southbound 50km/h 60‐65m 160m 120m 137m
*Represents the most stringent requirement.
The measured available sight distances exceed the required safe stopping sight distance and
the turning sight distance. The decision sight distance does not apply to this situation.
SUMMARY
The trip generation for the proposed development at worst generates 18 vehicles per hour
(vph) turning left out of the development. Even with the maximum density permitted, this
volume only increases to 28 vph. These volumes will not generate any operational issues at the
access location.
The proposed access location exceeds the minimum sight distance requirements required for a
50km/hr speed limit.
