Regulatory Context May 16, 2019

2.0 REGULATORY CONTEXT

Work around watercourses in British Columbia is primarily governed by:

• The Federal Fisheries Act, Sections 35 (serious harm to fish) and 36 (deleterious substances); • The BC Water Sustainability Act (WSA); and, • The Fish-Stream Crossing Guidebook.

2.1 THE FISHERIES ACT

The Fisheries Act, administered by Fisheries and Oceans Canada (DFO) contains two key provisions (Sections 35 and 36) aimed at protecting fish and fish habitat important for commercial, recreational and Aboriginal (CRA) fisheries:

Section 35(1): protects the productivity and sustainability of CRA fisheries by requiring projects to avoid causing ‘serious harm to fish’ unless authorized by DFO. This applies to work being conducted in or near water that support CRA fisheries, such as the Pacific Ocean. ‘Serious harm to fish’ is defined as “the death of fish or any permanent alteration to, or destruction of fish habitat”. Section 35 (1) of the Fisheries Act prohibits work from causing serious harm to fish that are part of a CRA fishery, or to fish that support such a fishery.

Section 36 (3): protects the health of fish and fish habitat through pollution prevention by prohibiting the deposition of deleterious substances into waters frequented by fish. The Fisheries Act defines deleterious substance as, “any substance that, if added to any water, would degrade or alter or form part of a process of degradation or alteration of the quality of that water so that it is rendered or is likely to be rendered deleterious to fish or fish habitat or to the use by man of fish that frequent that water.”

Certain types of project activities do not require DFO review or approval if best practices and prescribed mitigation measures are applied; however, such projects are still required to avoid ‘serious harm to fish’ and impacts to species listed under the Species at Risk Act (SARA).

2.2 THE WATER SUSTAINABILITY ACT

Under the WSA, “changes in and about a stream” means “any modification to the nature of the stream, including any modification of the land, vegetation and natural environment of a stream or the flow of water in a stream, or any activity or construction within a stream channel that has or may have an impact on a stream or stream channel”. Activities which may cause these changes require either an approval or notification under Section 11 of the WSA depending on the activity:

• Approvals: written authorization for changes in and about a stream that are of a complex nature. • Notifications: used for low risk changes specified in Part 3 of the Water Sustainability Regulation,

that have limited impact on the environment or third parties.

2.3 THE FISH-STREAM CROSSING GUIDEBOOK

The Fish-Stream Crossing Guidebook seeks to aid “forest and other resource managers and practitioners plan, prescribe, and implement sound fish-stream crossing practices to maintain fish passage and protect fish and fish habitat as required by the Forest and Range Practices Act and the federal Fisheries Act.

It provides practitioners with current legislative and technical reference material regarding fish passage, including British Columbia’s strategic approach to addressing fish passage at culverts.” (Fish-Stream Crossing Guidebook 2012).

This guidance was used to inform the recommendations for culvert design presented in Section 6.0 below.

3.0 PROJECT COMPONENTS

Otter Point Road is a Low Volume Road (LVR), located on Vancouver Island, near the Community District of Sooke, that intersects Highway 14 in Sooke, traverses north around Sooke and reconnects to Highway 14 west of Sooke. MoTI is embarking on a project to widen this road to improve safety for cyclists and pedestrians. MoTI’s project proposes to widen 2 kilometres of Otter Point Road between the Robinson Road area and the Sooke Municipal Boundary and provide a 1.5m wide paved shoulder on the north side (Figure 1). As part of the overall road widening project, MoTI is planning to upgrade several culverts to improve drainage in the area however only one culvert upgrade (located at Sta 125+00) has been identified as potentially impacting fish habitat. The planned upgrade at Sta 125+00 will replace an existing, undersized culvert, in order to allow for greater water conveyance under the road during periods of high precipitation (herein referred to as the “Project”). The location of this single culvert upgrade is the primary area of focus of this assessment. The culvert upgrade is necessary to prevent temporary backup of water on the upstream side of the culvert and lessen the potential for road flooding and/or undermining of the road itself during high flow conditions or following storm events.

The culvert replacement is currently planned for summer 2019 (August to September). Project construction activities are expected to include the following:

• Site preparation • Isolation and dewatering (if required) • Excavation and culvert replacement • Channel re-watering

Table 1 summarizes the construction activities associated with the Project components. The duration of the Project is anticipated to be approximately 20 days, with instream works occurring over an approximately 14-day period during the summer (e.g., low flow/dry period). Final construction timing will be determined once a contractor is selected for this work.

Table 1 Project Components

Project Component

Duration (approximate) Description

Site Preparation

7 days Preparation for culvert replacement on Otter Point Road. This includes removal of vegetation and clearing any laydown areas (if required).

Isolation of work areas1

4 days If water is present within the unnamed watercourse at the time of the culvert extension, then water will be diverted around the work area to prevent the mobilization of sediment downstream. The work area will be isolated through the installation of berms (e.g., bags filled with local material or clean fill) at the upstream and downstream ends of the work area. Once berm has been installed, a fish salvage will be completed prior to site dewatering. A submersible pump will then be placed on the upstream wetted side of the berm and will pump water to a release point downstream until the work area is dewatered to allow for construction to proceed in the dry.

Excavation and Culvert Replacement

7 days The existing culvert will be removed and the creek bed will be excavated to the appropriate elevation to facilitate the installation of the new culvert section. The new culvert will be either embedded or open bottom and will have streambed material placed within it and be backfilled.

Channel re-watering

2 days Following the complete installation of the new culvert, the dewatering structures will be removed, and flow re-established to the stream.

NOTE: 1 Isolation and berm installation will only be required if the unnamed watercourse at Sta 125+00 has flowing

water during instream works; however, the contractor should have materials on site (e.g., pump and sand bags) in the event that there is pooling water, or a rain event, that requires isolation and dewatering.

4.0 METHODS

4.1 DESKTOP BACKGROUND REVIEW

A desktop review of historic fish data was conducted to characterize the fish species that may occur in or near the Project area. This review relied on information available from the Government of British Columbia Habitat Wizard database (Habitat Wizard 2019).

4.2 SITE ASSESSMENT

A field survey with two Stantec Registered Professional Biologist (R.P. Bio) fisheries staff was conducted on April 11, 2019. The survey area included the watercourse at the immediate site of the culvert replacement as well as upstream to the connection to Poirier Lake (approximately 60 m) and downstream to the connection with De Mamiel Creek (approximately 170 m).

The survey consisted of an assessment of the existing fish habitat using assessment techniques based on Resource Inventory Committee guidelines (RIC 2001). The assessment collected information on watercourse slope, wetted width, bank height, water quality, as well as information on the overall quality

of the habitat for various life stages of the fish in the system (e.g., spawning, overwintering, rearing). Historic fish presence was established upstream and downstream of the culvert replacement location through the desktop portion of the assessment and as such no additional efforts were made to capture fish. Instead, the field survey focused on looking for any barriers to fish passage between Poirier Lake and De Mamiel Creek, as well as habitat quality, to provide comment on the species potentially using the Project area.

5.0 RESULTS

5.1 DESKTOP STUDY

The unnamed watercourse (Watershed Code 930-022100-02800-37100) associated with the proposed culvert replacement flows from Poirier Lake (Waterbody ID 315669) into De Mamiel Creek (Watershed Code 930-022100-02800). The unnamed watercourse flows north from an outlet in Poirier Creek through a culvert at the Project site (Otter Point Road) and continues northeast until it connects to De Mamiel Creek downstream (Figure 2). De Mamiel creek flows east until its connection with Sooke River and finally the Pacific Ocean in Sooke Bay (Juan de Fuca Strait).

There are no historic records for fish caught in the unnamed watercourse however both Poirier Lake and De Mamiel Creek have historical fish catch records associated with them (Appendix B). Fish species documented within Poirier Lake include rainbow trout/steelhead (Oncorhynchus mykiss), brown catfish (Ameiurus nebulosus), and prickly sculpin (Cottus asper). This lake is stocked annually with rainbow trout from Vancouver Island hatcheries (Habitat Wizard 2019) to supplement recreational fishing opportunities with the last release including 300 rainbow trout in early 2019 (FFSBC 2019).

De Mamiel Creek is a third order stream that is connected to the Pacific Ocean (Juan de Fuca Strait) through the Sooke River. De Mamiel Creek has documented historic fish catch records of Chinook (O. tshawytscha), coho (O.kisutch), and chum (O. keta) salmon, rainbow/steelhead and coastal cutthroat (O. clarki clarki) trout, coastrange (Cottus aleuticus) and prickly sculpin, smallmouth bass (Micropterus dolomieui), threespine stickleback (Gasterosteus aculeatus) and lamprey (Lampetra sp.) (Habitat Wizard 2019).

No federal species at risk are included in the historic catch records for Poirier Lake or De Mamiel Creek (Habitat Wizard 2019; BC CDC 2019); however, cutthroat trout (provincially blue listed) have been recorded in De Mamiel Creek (Habitat Wizard 2019; BC CDC 2019).

5.2 WATERCOURSE ASSESSMENT

Stantec fisheries biologists walked the length of the unnamed watercourse starting from the outlet of Poirier Lake to its eventual connection to De Mamiel Creek approximately 230 m downstream (Figure 2). The quantitative assessment focused primarily on the portion of the watercourse associated with the Project (culvert replacement) however the qualitative assessment was extended to the connection with Poirier Creek (approximately 60 m upstream) and De Mamiel Creek (approximately 170 m downstream).

Water exits Poirier Lake along its northeast side (Appendix A: Photo 1) and flows through a wide, wetted section where the watercourse spreads out and appears to be only partially confined (Appendix A: Photo 2). Continuing downstream the watercourse returns to a more defined channel and at the Project location the average wetted width was 1.9 m and the maximum water depth was estimated to be 0.8 m (wetted depth of 0.2 m at the time of the site visit) (Appendix A: Photos 3 and 4). No barriers to fish passage were observed between the Project location and Poirier Lake upstream; however, fish passage is likely to be semi-restricted at low flow times due to low water levels and thick vegetation at the lake outlet.

The watercourse flows under Otter Point Road through the culvert to be upgraded. On the upstream side of the road the bottom of the culvert is at grade with the watercourse however the downstream side is hanging (10 cm at the time of the visit) and spills into a 33 cm deep pool (29 cm residual pool depth) (Appendix A: Photo 6). The slope of the watercourse increases from approximately 2% on the upstream side of Otter Point Road to approximately 7% on the downstream side of the road. Several small cascade sections were observed immediately downstream of the road (Appendix A: Photo 7) before the watercourse gradient again decreased and the watercourse spread out from a single channel to a braided morphology which covered a larger wetted area (Appendix A: Photo 8). At this point the watercourse flows through private property and into a man-made pond with a barrier to fish passage (Appendix A: Photo 9). This barrier appears to be a predator deterrent fence (a perimeter fence and some traps were observed around the pond) for a small flock of ducks who use the man-made pond (Appendix A: Photo 10). Due to the presence of this barrier no movement between the unnamed watercourse above the barrier and De Mamiel Creek downstream is possible. Continuing downstream from the pond, the watercourse flows within a defined channel (Appendix A: Photo 11), through an embedded culvert (Appendix A: Photo 12) before connecting with De Mamiel Creek (Appendix A: Photo 13). While fish passage from De Mamiel to the upstream areas of the unnamed watercourse is currently not possible, the unnamed watercourse does contribute to water quality within the fish-bearing reaches of De Mamiel Creek downstream.

Water quality measurements were collected on the unnamed watercourse at the planned culvert replacement location. The temperature (10.5 °C), dissolved oxygen (8.84 mg/L), pH (6.25), conductivity (66.4 S/cm) and turbidity (clear). With the exception of pH and dissolved oxygen, all of the parameters are within the guidelines for use by aquatic life including rainbow trout (Ministry of Environment & Climate Change Strategy 2018). The pH is slightly below the recommended level (6.5) and dissolved oxygen is slightly lower than the recommended concentration for embryo/alevin (11 mg/L). These values are not low enough to prevent fish from using this habitat however they slightly decrease the quality of that habitat.

Culvert Design Recommendations May 16, 2019

9

Based on the results of the assessment, the unnamed watercourse is classified as an S3 watercourse (fish bearing; 1.5 ≤ 5 m) at the culvert location based on Forest Practices Code of British Columbia guidance (1998). This classification is based on the watercourse dimensions recorded during the site visit and the assumption that the watercourse is fish bearing in the Project area due to a lack of observed barriers between known fish bearing habitat (Poirier Lake) and the culvert replacement site. Due to the barrier installed downstream, the potential fish species that could be present within the Project area is limited to those inhabiting Poirier Lake as species from De Mamiel cannot move upstream to the Project area and therefore are excluded. As such, rainbow trout is the main species of concern for this work and will inform timing windows of least risk in Section 7.0 below.

The fish habitat within the unnamed watercourse was classified as marginal. This ranking was based on a lack of suitable spawning habitat, an absence of deep pools suitable for overwintering, and moderate stream cover in the form of undercut banks and overhanging vegetation. As such, the fish habitat is defined as having low productive capacity and only marginally contributing to fish production (Fish-Stream Crossing Guidebook 2012).

6.0 CULVERT DESIGN RECOMMENDATIONS

The Provincial guidance for culvert replacement (Fish-Stream Crossing Guidebook 2012) was used to determine the requirements for culvert design for the Project. Based on the site assessment results with a classification of marginal habitat, a maximum wetted width of 1.9 m, and a slope of <3% either an open-bottom (arch culvert) or a closed bottom structure is recommended. As per the Fish Stream Crossing Guidebook (2012), closed-bottom structures do not require a Fisheries Act Authorization provided that: a) the stream channel width is less than 2.5 m, b) the culvert is embedded to replicate the streambed inside the pipe, and c) construction adheres to the appropriate fisheries timing window.

MoTI has indicated that they plan to use a closed-bottom structure. The Fish Stream Crossing Guidebook provides design and construction guidance based on the stream characteristics of the site. Based on this guidance the culvert will need to be embedded to retain stream substrate, to provide fish habitat, and allow for fish passage. Based on the average wetted width of upstream section of the creek being approximately 1.9 m, the structure should be at a minimum the same diameter and should also be sized to accommodate at least a 100-year return period peak flow after embedment (minimum MoTI requirement). Stantec engineers have confirmed that the current recommendation of a 1.9 m culvert will be able to pass a 200-year return period peak flow. The embedment should be at least 40% of the culvert diameter or 0.6 m, whichever is greater. If a pipe-arch or box culvert is used instead, embedment depth should be at least 20% of the vertical rise of the arch. Specific guidance on substrate placement within the culvert can be found in section 4.2.1.4 of Fish-Stream Crossing Guidebook (2012). Regardless of the type of structure selected, it should be installed to match the existing stream gradient to the extent possible.

Mitigations Measures May 16, 2019

10

7.0 MITIGATIONS MEASURES

The Project has the potential to impact aquatic life (including fish and fish habitat) through works both at the site and downstream (i.e., changes in water quality). In order to avoid adverse effects to aquatic life, both at the Project location and downstream, Stantec recommends that the measures in Table 2 be implemented. These measures are not considered exhaustive and should be incorporated into a comprehensive Project-specific environmental management plan (EMP) to be developed prior to construction.

Table 2 Mitigation Measures

Project Activity Mitigation Measures

Site Preparation

• Removal of shrubs and grading the shoulder of existing road

• Construction of a temporary staging area for construction materials/equipment adjacent to Graham Creek

• Limit the disturbance to vegetation along any laydown areas. • Install silt fencing at the top of the creek bank to prevent material from

entering the creek. • An Environmental Monitor (EM) will be present during initial clearing,

infilling and grading of the road and laydown areas to prescribe additional mitigation measures, as required.

• If tree clearing is planned to occur within the bird nesting window (late March to Mid-August) then a bird nest sweep will need to be conducted within 7 days of clearing. If nests are observed an exclusion area will be flagged where no activity will be permitted until the birds have ceased using the nest.

Isolation of Work Areas1

• Installation of berms • Flow diversion

• Isolate the work area using upstream and downstream berms constructed out of clean material.

• Use local accumulated material in berm creation. • Conduct a fish salvage within the isolated area to remove fish prior to

instream works. Details of the Fish Salvage Plan will be outlined in the EMP

• Where feasible, time instream work to occur during least risk window for target species (rainbow trout) August 15–September 152. Work outside of this window should only occur after discussion with a Qualified Environmental Professional and may require additional mitigation measures.

• Follow DFO guidance for intake screening to prevent fish kills (DFO 1995).

Excavation and Culvert Replacement

• The existing culvert will be exposed, removed and replaced with a larger culvert.

• Maintain the integrity of water quality downstream (i.e., monitor downstream turbidity and compare to relevant water quality guideline).

• Conduct excavation “in-the-dry”. • Pump any turbid water in the excavation to a “settling basin” dug in the

middle of the sediment build-up area surrounded by one of the boulder berms.

• Prohibit re-fueling or maintenance of heavy machinery within 30 m of the creek.

• Verify that heavy machinery and trucks are maintained and free of leaks prior to entering work area.

Permitting Recommendations May 16, 2019

11

Table 2 Mitigation Measures

Project Activity Mitigation Measures

• The existing culvert will be exposed, removed and replaced with a larger culvert. (cont’d)

• Machinery will work from dry locations and not in the active stream channel; if entry into the active stream channel is required, this will be reviewed with an EM beforehand.

• Design of the culvert will be such that it is either open bottom or embedded closed bottom and is designed to meet fish passage standards.

Channel Re-watering

• Following the installation of the new culvert and the final contouring of the creek banks, the berms or dry sacs will be removed.

• Monitor water quality and ensure that it meets the relevant water quality guidelines for fish-bearing water downstream.

NOTE: 1 Isolation and berm installation will only be required if the unnamed creek at Sta 125+00 has flowing water

8.0 PERMITTING RECOMMENDATIONS

Serious harm to fish is not expected to occur as a result of the culvert upgrades associated with the Project provided mitigation and monitoring measures outlined in this assessment are applied during construction, and the planned culvert is designed according to guidelines outlined in the Fish Stream Crossing Guidebook (2012). As such, no formal DFO review is required, as described in Section 6.0. Mitigation measures developed as part of the Project-specific EMP (to be developed by MoTI prior to construction) are expected to further avoid or limit downstream effects to fish bearing areas (i.e., De Mamiel Creek).

The results of the field assessment indicate that the watercourse fits the definition of a stream under the WSA. Based on current Project understanding, the work is expected to meet the criteria for a notification (no change approval or authorization required) under the Water Sustainability Regulation (Part 3). Stantec will prepare this notification on behalf of MoTI. This notification must be submitted to FrontCounter BC a minimum of 45 days before beginning work.

In the event that a fish salvage is necessary prior to construction, a scientific fish collection permit issued the Province will need to be obtained.

8.1 OTHER CONSIDERATIONS

If water is present (flowing or pooled) in the watercourse at the time of construction, there is the possibility for tadpoles or juvenile frogs/toads to be present in the area. A Qualified Environmental Professional should evaluate the site prior to any water diversion activities to confirm whether amphibians are present along the length of the watercourse to be dewatered. In the event that an amphibian salvage is required, a wildlife permit will need to be applied for. This permit includes the need to develop an animal handling and salvage plan.
