1.0 INTRODUCTION

Watt Consulting Group was retained by Boardwalk REIT to conduct a traffic impact assessment for a proposed residential development at 339, 341, and 345 Island Highway in the Town of View Royal. This study assesses traffic impacts of the proposed multi-family residential buildings, reviews the site access, and assesses the need for any mitigation measures. The study reviews the existing traffic operations along with the post development and long-term conditions for all modes of transportation.

1.1 STUDY AREA

See Figure 1 for the study area and location. The study area includes the following intersections:

• Island Highway / Prince Robert Drive
• Island Highway / Burnett Road
• Island Highway / Jedburgh Road

Figure 1: Study Area and Site Location

2.0 EXISTING CONDITIONS

2.1 LAND USE

The proposed development site is composed of three residential lots (339 / 341 / 345 Island Highway) and the existing land use is multi-family residential rental units. The surrounding area of the development is mostly residential along Island Highway and Prince Robert Drive. The View Royal Fire Department buildings were recently constructed just east of the proposed site on Island Highway. To the north, across from the development, there is the Fort Victoria RV Park.

2.2 ROAD NETWORK

The proposed development is located on the south side of Island Highway between Prince Robert Drive and View Royal Fire Department. Island Highway is under the jurisdiction of the Ministry of Transportation and Infrastructure. Burnett Road and Jedburgh Road are under the jurisdiction of the Town of View Royal. All roads within the study area have a maximum speed limit of 50 km/h. A description of all relevant roads in the area is provided below.

Island Highway is a two-lane highway with a functional classification as a Major Road. There are many private property accesses present, and the turning movements associated with them cause conflict and delay along the corridor. There are bike lanes on both sides, but limited sidewalks along most of the roadway (new sidewalk installed along the View Royal Fire Department frontage).

Prince Robert Drive is a two-lane local road (site access road), which faces the west side of the development. There is no sidewalk and limited shoulders provided along the roadway.

The intersection of Island Highway / Prince Robert Drive is stop-controlled with no separate turn lanes. Sight distance for northbound left turning traffic (looking to the left along the highway) from Prince Robert Drive is limited due to the horizontal curvature and vegetation.
