Carp Road Widening from Hazeldean Road to Highway 417
The City of Ottawa is the proponent of a Class Environmental Assessment (EA) Schedule "C" to study the proposed widening of Carp Road from Highway 417 to Hazeldean Road. This Statement of Work describes the City's intentions with respect to the study's scope, methodology, public consultation and deliverables for this study.
Rapid growth in the Stittsville area has increased traffic volumes on Carp Road leading to congestion during the peak periods. In addition, new growth in the area includes Stitts Corners, expansion of the developing community along Rothbourne Road and possible development at the old Stittsville Flea Market site.
The City's Transportation Master Plan identifies the widening of Carp Road to four lanes between Highway 417 and Hazeldean Road as a Phase 2 project (2016-2022).
Key considerations for this EA study include the following:
- Detailed evaluation of future transportation demand for the City's north-south direction of travel and public areas of interest
- Cycling and pedestrian needs in the arterial roadway corridor
- Full evaluation of any potential impacts on wetlands and other natural environment areas
- Stormwater management/hydrology
- Preserving the rural character in the rural areas
- Effects on existing community
Project Scope, Tasks and Deliverables
The study will be consistent with the approach and requirements set out in the Provincial Environmental Assessment Act. All relevant environmental inventories and analysis undertaken for this assignment will be of sufficient scope to satisfy the Provincial EA requirements.
1.1 Study Area
While the widening is focused on the 2 km segment between Highway 417/Carp Road Interchange and Hazeldean Road/Carp Road intersection, the study area (Figure 1) includes the section of Carp Road south of Hazeldean Road (to Stittsville Main Street) to ensure that downstream effects of the proposed widening are fully addressed. Recent growth in the area will also be taken into consideration.
The study area will include the operation of Highway 417 Interchange Ramps on the north side of Highway 417 as well as the operation of the Main Street intersection to the south. The study area may be adjusted as necessary in order to comprehensively identify the influences on, and the effects of the project as options are developed.

2. Environmental Assessment
The undertaking of the Environmental Assessment comprises the following tasks outlined below.
2.1 Project Need
Although this proposed widening has been identified in the TMP, the need for additional arterial capacity and an examination of need and assumptions is required under the Provincial Environmental Assessment Act. This exercise will be carried out by forecasting travel demand for the south end of the City and determining both existing and future needs for a facility with respect to the impact on north-south travel demand/distribution, economic benefits and links to major employment destinations. In addition, the study will identify current and projected transportation problems and opportunities within the study area.
2.2 Existing Conditions
An inventory of the social, economic (agricultural, employment, retail etc.), physical and natural environments within the study area will be compiled. The inventory will consider all available background material and where necessary, supplement this information through on-site surveys and/or detailed studies. The inventory must be of sufficient detail to enable the analysis and evaluation of alternative transportation solutions, designs and mitigating measures.
In general, the inventory will identify and describe those aspects of the environment that could potentially affect, or be affected by the undertaking. Some of the specific aspects of the environment associated with this project include:
- Land uses, adjacent private property and neighbouring communities
- Transportation and infrastructure facilities (existing and planned), including cycling and recreational pathway corridors/routes
- Utilities including water, sanitary, hydro, gas, cable, phone, fibre optic, etc.
- Green spaces and natural areas
- Water courses
- Current storm water drainage patterns
- Landscape Architecture
- Heritage and archaeological conditions
- Air quality
- Noise and vibration
The existing conditions must be completed for the entire study area so that as alternative solutions and designs are developed and analyzed, the cumulative effects can be examined.
2.3 Alternative Solutions
The Study will identify and examine all reasonable alternatives to the widening of Carp Road from Hazeldean Road to Highway 417.
The key components of this stage include:
- Identify alternative solutions to address transportation problems including:
- Do nothing
- Expand and enhance public transit service (including Park and Ride Facilities) to/from the south suburban areas and rural villages
- Expand and enhance cycling routes
- Implement transportation demand management (TDM) measures to reduce travel demand; and
- Expand other arterial roadways in the north-south direction
- Develop evaluation criteria and indicators to assess the impacts (with consideration to possible mitigation measures) on the environment by the various solutions
- Analyze and evaluate the alternative solutions and select the preferred solution(s).
The travel-forecasting component included in this stage of the EA must:
- Identify the needs for all modes of transportation including walking, cycling, transit, auto and truck
- Incorporate the principles (e.g. mode share targets etc.) of the current Official Plan and Transportation Master Plan in balancing demand to capacity while promoting the desire to increase transit use
- Provide supporting analysis and recommendations for the alternative or supporting infrastructure.
2.4 Design Alternatives
The study will identify and evaluate various design alternatives for the selected solution. Alignment and cross-section design alternatives will be developed based on consideration of constraints within the study area, input from the public and approval agencies, landowners, as well as City guidelines/standards/practices. All proposed designs will include any required modifications on connecting roadways (public or private).
2.5 Evaluation Process
A comprehensive evaluation methodology and list of criteria will be developed to assess the various alternative designs. The evaluation process will be clearly described and documented.
2.6 Impact Assessment
The effects of each alternative design on the environment will be thoroughly evaluated. Mitigation measures and associated implications (e.g. cost of mitigation etc.) are to be identified and considered in the evaluation process. The study must clearly identify the initial impacts of each alternative as well as the net post-mitigation effect using quantifiable indicators and measures wherever possible.
Effects on traffic operations will be evaluated in accordance with current City guidelines and practices. To ensure that all impacts are appropriately evaluated, detailed studies will be required for specific issues such as:
- Air quality
- Archaeology and heritage
- Impact on existing homes
- Roadway drainage and storm water management
- Subsurface conditions, geotechnical and utilities
- Vegetation/terrestrial habitat and aquatic habitat.
Developing an accurate project baseline budget is an essential component of this study and the resulting project cost will contribute to the City’s short and long range capital budget forecasting, priority setting, and development charges strategy. The project budget will also form the basis for funding discussions with senior levels of government, where appropriate. The baseline budget will be developed using a Work Breakdown Structure (WBS) format in current dollars, and include contingency allowances.
Project costing is a fundamental criterion in the evaluation of alternatives and will be a key consideration in the development of implementation strategies.
2.8 Recommended Plan
Following the evaluation of alternatives and determining all necessary mitigation measures to minimize any adverse impacts of the project, a recommended plan will be developed. This will include:
- A detailed written description of the undertaking including the design parameters
- Functional design drawings (1:500 scale, plan and profile) for the preferred alignment with a geo-referenced horizontal alignment, vertical profile, grading, drainage and property envelope
- Roadway cross-section drawings for typical sections as well as at critical areas
- Mitigation measures to reduce the environmental impacts of the project
- Landscape design plan
- Property requirements plan
- Storm water management and roadway drainage requirements, as well as other infrastructure requirements
- Infrastructure implementation/staging plan (e.g. water mains, sewers etc.)
- Implementation (phasing) plan and detour plans during construction
The recommended plan will clearly identify and set out the requirements and timing for all subsequent approvals required to proceed with the construction phase of the project. The recommended plan will be presented to Transportation Committee and Council for approval.
2.9 Environmental Study Report
An Environmental Study Report (ESR) will be prepared to document the entire study process including the approved design, mitigation measures, and consultation efforts. The ESR will be placed on public record for a minimum 30-day review period as per the Environmental Assessment Act.
