1.0 INTRODUCTION
The City of Surrey is proposing improvements to 105A Avenue from Whalley Boulevard to 150 Street (Figure 1). The project supports the City’s vision for the proposed City Centre and Light Rail Rapid Transit (LRT) on 104 Avenue, and part of a multi-phase program to improve the 105A Avenue corridor between 132 Street and 156 Street. The 105A Avenue widening and new road construction are planned to provide an alternate route to for vehicular traffic, local neighbourhood access and circulation, and a continuous cycling corridor. The proposed improvements will also address forecasted increases in local traffic volume (City of Surrey 2016). Improvements will also include the relocation of the existing 104 Avenue water main and storm sewer to 105A Avenue, in order to facilitate future LRT construction. The combined activities are referred to as the 105A Avenue Improvements project or “the Project”.
At the request of Aplin & Martin Consultants Ltd. (Aplin Martin), Hemmera Envirochem Inc. (Hemmera) has prepared an Environmental Impact Assessment (EIA) that describes the scope of the Project and its potential effects on four environmental components:
• Fish and fish habitat (including riparian areas);
• Vegetation;
• Wildlife and wildlife habitat; and
• Species at risk.
In support of this EIA, desktop review of available literature and other online resources was undertaken followed by multiple site visits, including:
• Baseline vegetation and wildlife habitat suitability assessments (February 2 and February 14, September 9, 2017);
• Detailed vegetation and ecosystem assessment: peat bog area (September 9, 2017);
• Fish habitat and reconnaissance sampling on Bon Accord Creek (February 2, September 9, and November 26-27, 2017);
• Focused species at risk habitat suitability assessment surveys for Oregon forestsnail and Pacific water shrew (January 3 and 10, 2018); and
• Stand watch for the red-tailed hawk nest north of 140B Street (January 12, 2018).
For the purposes of this EIA, the study area is defined as the drainage ditches intersecting with the proposed 105A Avenue widening and new road section between Whalley Boulevard (to the east) and 144 Street (to the west), as well as fish and wildlife habitat located within Hawthorne Park, between 106A Avenue (to the north) and 104 Avenue (to the south; Figure 1). An expanded study area (a 1 kilometer (km) area on either side of the proposed improvements) was specifically applied to the assessment of terrestrial species at risk.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – EIA - 2 - January 2018
Potential effects associated with the Project are described in this EIA, along with recommendations for site- specific mitigation measures to help avoid or minimize potential adverse impacts on these environmental components.
Residual effects on these environmental components (following application of mitigation measures) were also assessed, including a determination of whether changes to local drainages and proposed stormwater tie-ins will result in serious harm to fish that form part of a commercial, recreational, or Aboriginal (CRA) fishery consistent with provisions in the federal Fisheries Act (2012).

3.0 REGULATORY BACKGROUND
This section considers the federal and provincial environmental legislation that may apply to the Project. Each of these pieces of legislation provides regulatory considerations that guided assessments of potential impacts to the natural environment, including fish, vegetation, wildlife, and species at risk that may be present in Hawthorne Park. They were also used to develop proposed mitigation measures to minimize the effects of the Project.
3.1 FEDERAL LEGISLATION
3.1.1 Fisheries Act
The Fisheries Act (SC 1985, c. F-14) protects the quality and integrity of fish habitats for CRA fisheries. Recent changes to Sections 32 and 35 of the Fisheries Act prohibit activity that may cause serious harm to fish, defined as the death of fish, or any permanent alteration to or destruction of fish habitat1, unless authorized by Fisheries and Oceans Canada (DFO). Other sections of the Fisheries Act that are applicable to the Project include Section 36(3) that prohibits the deposition of deleterious substances to waters frequented by fish, and Sections 38(4) and 38(5) that require a contravention of either Sections 35 or 36(3) be reported without delay.
3.1.2 Species at Risk Act
The Species at Risk Act (SARA) was considered in the assessment of potential impact of the Project on species at risk. For species listed as threatened or endangered on Schedule 1 of SARA a residence description and (where sufficient information exists) critical habitat must be described, spatially or based on biophysical characteristics, in a federally-accepted provincial recovery strategy within one year (if listed as endangered) and within two years (if listed as threatened or extirpated) on Schedule 1 of the SARA.
Relevant sections of SARA that pertain to the proposed work in Hawthorne Park include:
• General Prohibitions Section 32(1): No person shall kill, harm, harass, capture or take an individual of a wildlife species that is listed as an extirpated species, an endangered species or a threatened species;
• Damage or destruction of residence, Section 33: No person shall damage or destroy the residence of one or more individuals of a wildlife species that is listed as an endangered species or a threatened species;
1 Fish habitat is defined as “spawning grounds and nursery, rearing, food supply, and migration areas on which fish depend directly or indirectly to carry out their life processes.” In the case of the Project, this includes all yellow, red, and red-dash coded watercourses within the Project area.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – EIA - 9 - January 2018
• Application Section 34(1): With respect to individuals of a listed wildlife species that is not an aquatic species or a species of birds that are migratory birds protected by the Migratory Birds Convention Act, 1994, Sections 32 and 33 do not apply in lands in a province that are not federal lands unless an order is made under subsection (2) to provide that they apply; and
• Section 49.1: states requirements for an action plan to include identification of Critical Habitat, to the extent possible.
Federal acceptance is required to enact legal protections afforded to residences as described within approved recovery strategy documents accepted by Environment and Climate Change Canada (ECCC) under SARA. The industry standard for compliance with SARA, when a residence is not defined for a species, or when critical habitat has not been identified within a Project area, is relegated to due diligence on behalf of the proponent. By reasonable interpretation this requires identification of potential risks to important habitat elements that may be used by a species at risk (under an assumed definition of residence) and implementing appropriate management practices and mitigation measures that are reasonably expected to minimize potential effects to identified species.
For species identified as Special Concern (on Schedule 1 of SARA) management plans are prepared. When accepted by the federal government the management plan sets direction to afford conservation consideration to the species. Success in species conservation depends on the commitment and cooperation of many different constituencies involved in implementing directions set out in the Management Plan. Implementation of direction, as described within a management plan, is subject to appropriations, priorities and budgetary constraints of the participating jurisdictions and organizations.
The federal government is in violation of SARA if a proposed management plan or recovery strategy is not approved within 90 days of public posting. This period has expired for the:
• Oregon forestsnail proposed Recovery Strategy (posted as proposed 2014);
• Western screech-owl (draft) Recovery Strategy (not yet posted publicly);
• Western toad proposed Management Plan (posted as proposed 2016);
• Monarch Management Plan (posted as proposed 2014); and
• Vancouver Island Beggarticks proposed Management Plan (posted as proposed 2015).
As such, there is no accepted definition of residence or any of these species and no accepted spatially described or designated critical habitat for Oregon forestsnail or western screech-owl. Proposed critical habitat has been identified for Oregon forestsnail; however, the Project area does not occur within areas identified as proposed critical habitat for this species.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – EIA - 10 - January 2018
Similarly, there is no approved federally mapped critical habitat within the Project area. Regardless of delinquency by ECCC Hemmera attempted, to the extent practicable, to identify important habitat elements that may be used by a species at risk (under an assumed definition of residence).
3.1.3 Migratory Birds Convention Act
The Migratory Birds Convention Act (SC 1994, c.22) protects various species of migratory birds including gamebirds, insectivorous birds, and non-gamebirds. This Act restricts the possession of live and dead migratory birds and bird parts, and prohibits the taking of migratory bird nests and the deposit of harmful substances in waters or areas frequented by migratory birds.
3.2 PROVINCIAL LEGISLATION
3.2.1 Water Sustainability Act
Any changes in and about a stream in the province of BC requires application under Section 11 of the BC Water Sustainability Act (SBC 2014, c. 15). Changes include any modification to the nature of the stream, (e.g., land, vegetation, natural environment, flow), or any activity or construction within the stream channel that may result in an adverse effect. In the context of the 105A Avenue Extension Project, this includes construction, removal, or maintenance of culverts and bridges, stormwater outfalls, and construction of stormwater management systems.
The following permits have been obtained or have been submitted under the Water Sustainability Act. Copies of received permits are provided in Appendix B:

Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – EIA - 11 - January 2018
3.2.2 Wildlife Act
Wildlife are afforded some protection under the BC Wildlife Act. Relevant sections of the act that pertain to the proposed work in Hawthorne Park include:
• Section 34 (A, B, C): A person commits an offence if the person, except as provided by regulation, possesses, takes, injures, molests or destroys: (a) a bird or its egg; (b) the nest of an eagle, peregrine falcon, gyrfalcon, osprey, heron or burrowing owl; or (c) the nest of a bird not referred to in paragraph (b) when the nest is occupied by a bird or its egg.
3.2.3 Riparian Areas Protection Act, Riparian Areas Regulation
The Riparian Areas Regulation (RAR) was enacted under Section 12 of the Fish Protection Act which was subsequently re-titled the Riparian Areas Protection Act in 2016. The RAR requires local governments to protect riparian areas during residential, commercial, and industrial development by ensuring that a Qualified Environmental Professional (QEP) assesses waterbodies (as defined in the Regulation) and determines a suitable setback. The RAR may be used to designate a reduced setback in some instances where a municipal streamside protection or zoning bylaw has prescribed streamside development areas.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – EIA - 12 - January 2018
4.0 METHODS
This section describes the methods used and information sources reviewed to gather data for each of the study components. For the purposes of this EIA, the study area is defined as the drainage ditches intersecting with the proposed 105A Avenue widening and new road section between Whalley Boulevard (to the east) and 144 Street (to the west), as well as potential fish and wildlife habitat located within Hawthorne Park, between 106A Avenue (to the north) and 104 Avenue (to the south; Figure 1). This study area encompasses the proposed road widening and new road construction area, and provides a suitable buffer zone for information-gathering purposes. An expanded study area (1 km) was specifically applied to species at risk for reasons described below in Section 3.4.
4.1 FISH AND FISH HABITAT
This section considers the methods used to characterize instream fish habitat and associated riparian fish habitat within the study area.
4.1.1 Desktop Studies
Fish habitat classifications for watercourses within the study area were initially identified through desktop review using the City of Surrey Mapping Online System (COSMOS 2017). The City of Surrey maintains a Watercourse Classification Map for all city watercourses (including ditches), based on their value as habitat for salmonids and regionally-significant fish species, as described below in Table 2.
Table 2 City of Surrey’s Watercourse Classification System
Classification Definition Inhabited by salmonids year-round or potentially inhabited year-round with access A (Red) enhancement. A/O (Red-Dashed) Potentially inhabited by salmonids seasonally. B (Yellow) No fish present. Significant food/nutrient contribution. C (Green) No fish present. Insignificant food/nutrient contribution.
Fish presence data were obtained from the BC Ministry of Environment’s Fisheries Inventory Data Query (FIDQ) system (FIDQ 2017) and online mapping system (iMap BC 2017).
4.1.1.1 Riparian Setback Assessment
Construction, maintenance or operation of municipal or public utility works and services are exempt from Development Permit Area requirements and setbacks under the City of Surrey Zoning Bylaw 12000 Part 7A. In order to maintain riparian function associated with watercourses in the Project area, setbacks assessment considered both the Riparian Areas Protection Act Riparian Areas Regulation (RAR), BC Reg. 376/2004, riparian Best Management Practices (BMPs), the Zoning Bylaw and discussions with City of Surrey Environmental staff. A final determination and approval of the setbacks was given by City of Surrey Environmental staff.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – EIA - 13 - January 2018
Under the City of Surrey Zoning Bylaw, riparian setbacks are determined by morphology of the stream (natural vs. channelized) and classification (Class A, A(O), or B). Setbacks are measured from top of bank. It is possible to obtain a lesser setback using the RAR. The RAR methodology allows a Qualified Environmental Professional to assess the width and morphology of the watercourse, and determine an appropriate setback based on a set of parameters. The setback may extend between 5 m and 30 m, depending on the characteristics, width and gradient of the watercourse, and the characteristics of the surrounding riparian area. The setbacks established on each watercourse in the study area were used to identify Project related impacts to riparian habitat and determine appropriate mitigation measures.
4.1.2 Field Studies
Two field assessments were conducted on February 2 and September 7, 2017 by Hemmera biologists to ground-truth the findings of the desktop study. Site-specific data were collected on drainage channel width and morphology, evidence of flow/scour, connectivity, fish habitat value, and riparian integrity and value. In situ water quality data (i.e., temperature, pH, conductivity, and dissolved oxygen) were also collected to complement visual observations. Survey methods followed standards and procedures prescribed in the Reconnaissance (1:20,000) Fish and Fish Habitat Inventory (Resources Information Standards Committee; RISC 2001).
In addition, eight baited minnow traps were set on November 26, 2017: two upstream of the culvert at 108 Avenue; two downstream of the culvert; and four in Bon Accord Creek Ponds. The traps were retrieved on November 27th, 2017, approximately 24 hours after they were set. The culvert under 108 Avenue was also assessed for fish passage.
4.2 VEGETATION
Vegetation studies for the study area includes overview studies of ecosystems and vegetation communities, with a more focused study on the remnant bog habitat located in the south section of the park.
4.2.1 Desktop Studies
A variety of vegetation types and species, including invasive plants, have the potential to be present within the study area. Information was gathered from the following sources:
• On-line databases (BC Conservation Data Centre (CDC), Committee on the Status of Wildlife in Canada (COSEWIC), eFlora);
• Review of available ortho-imagery (Google Earth, City of Surrey WebMap (COSMOS)); and
• Background documents and previous reports (Pojar, Klinka, and Demarchi 1991).
In addition, an ecosystem map was created for the remnant bog habitat using the provincial Standard for Terrestrial Ecosystem Mapping in British Columbia in the Field (RISC 1998) as a guide.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – EIA - 14 - January 2018
4.2.2 Field Studies
Biologists visited the park in February and September 2017 to assess ecosystems in the park. Indicator species and communities were surveyed using the methods provided in the Standard for Terrestrial Ecosystem Mapping in British Columbia in the Field (RISC 1998) and Field Manual for Describing Terrestrial Ecosystems in the Field (2010) as guides.
4.3 WILDLIFE AND WILDLIFE HABITAT
Several species of wildlife have the potential to use habitats within the study area.
4.3.1 Desktop Studies
Methods used to determine potential wildlife species occurring in the study area and to better understand potential wildlife habitat values included:
• On-line databases (BC CDC, COSEWIC, Wildlife Tree Stewardship (WiTS), eFauna);
• Surrey’s Biodiversity Conservation Strategy and Green Infrastructure Network; and
• City of Surrey WebMap (COSMOS).
4.3.2 Field Studies
Biologists visited the park in February and September 2017, and January 2018. Incidental observations of wildlife were recorded during those visits, including evidence of birds (auditory and visual), wildlife sign (woodpecker activity, feces, fur, etc.), and included ground-based visual surveys for raptor nests.
4.4 SPECIES AT RISK
4.4.1 Desktop Studies
Information related to provincially or federally listed species at risk with the potential to be present within the study area was gathered from a review of known species at risk occurrences through online and proprietary internal databases. The study area for species at risk desktop-based searches was expanded to an area of 1 km on either side of the Project alignment. This expanded study area was considered sufficiently large to capture recorded occurrences of species at risk, especially species that may move through and within the study area (such as birds and fish) and plant species that may have expanded their range since last detection.
An exhaustive list of wildlife and plant species at risk with potential to occur in the study area was created by querying HectaresBC, BC Species Inventory web explorer (WSI), proprietary databases maintained by Hemmera, and the BC Conservation Data Centre (CDC) Species and Ecosystem Explorer.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – EIA - 15 - January 2018
Next, the list was filtered to create a list of species with potential to occur in the region by including species of management concern as per the following criteria:
• Existing regulatory requirement for focused species management: Listed as Endangered, Threatened or Special Concern under Schedule 1 of the federal Species at Risk Act (SARA); Afforded management consideration under the federal Migratory Birds Convention Act; and Afforded management consideration under the BC Wildlife Act (specifically under S.34c).
• Conservation concern: These include species that are red- or blue-listed by the BC CDC.
Finally, the potential for each species to occur in the study area was assessed. For each species, the potential for spatial and temporal presence in the study area was determined based on the literature, previous field investigations in the general study area, and the BC CDC. In addition, an accepted recovery strategy was available, and was considered for Pacific water shrew and common nighthawk, red-legged frog, and Oregon forestsnail (acceptance as final, by ECCC, is currently overdue). A draft recovery strategy (not-yet publicly available) was also considered for western screech-owl (public posting of a proposed recovery strategy for western screech-owl, by ECCC, is currently overdue). Accepted management plans were not available for four Schedule 1 listed Special Concern species included in this report, including: western toad, painted turtle, monarch, and Vancouver Island Beggarticks. Instead, proposed management plans were considered for each of these four species.
Each species in the final list was then assigned a rating that describes the potential for a species to occur within the study area. Species can be assigned a rank of high, medium, low or nil for potential presence in the study area based on occurrence records, known habitat associations, and professional experience.
The rankings are as follows:
Nil: current understanding of the species’ range and/or known species habitat associations suggests that the species is not expected to occur within the study area. Species occurrence in the study area would be considered accidental.
Low: current understanding of the species’ range and/or known species habitat associations suggests that the species is unlikely to occur within the study area with regularity or in adequate density to facilitate a functional population. Several ecological life-requisite stages would be challenged based on existing habitat conditions in the Project area and/or connectivity with larger, more contiguous occurrence of the species.
Medium: current understanding of the species range and/or known species habitat associations suggests that the species is expected to occur in the study area on a temporary or regular (i.e., predictable) seasonal basis and in densities that facilitate persistence of a functional population within the study area.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – EIA - 16 - January 2018
High: current understanding of the species’ range and/or known species habitat associations suggests that the species is expected to occur in the study area regularly, and in densities that would be expected to occur in provincial benchmark habitats2.
In addition, the following documents were reviewed prior to field studies to guide habitat assessments and to confirm the rankings for each species as per the criteria detailed above:
• Recovery Strategy for Pacific Water Shrew in Canada (final); • Recovery Strategy for Common Nighthawk in Canada (final); • Recovery Strategy for the Oregon Forestsnail in BC (proposed); • Recovery Strategy for the Western Screech-owl in BC (draft, not yet posted); • Management Plan for the Northern Red-legged frog in BC (final); • Management Plan for the Western Toad in BC (proposed); • Management Plan for the Monarch in Canada (proposed); and • Management Plan for Vancouver Island Beggarticks in BC (proposed).
4.4.2 Field Studies
Field studies were focused on assessing habitat suitability for species at risk with potential to occur in the study area. Field assessments followed accepted methods, where applicable, including qualitative and quantitative determination of available habitat. The potential for occurrence of, or effects on, most species at risk can be discounted with desktop-based or general field assessments, or the application of temporal mitigation to avoid or minimise effects.
Four species at risk were identified as having potential to be present in the study area; therefore, specific and targeted field-based assessments were needed. Western screech-owl (Megascops kennicottii kennicottii) nest cavities, great blue heron (Ardea herodias fannini) nests, Oregon forestsnail (Allogona townsendiana), and Pacific water shrew (Sorex bendirii).
4.4.2.1 Western screech-owl
Western screech-owl have potential to nest within the study area, as many suitable snags exist within the riparian area of Bon Accord Creek. A ground-based habitat suitability and cavity tree search was conducted based on known habitat requirements (MOE 2013) and included trees (>15 cm diameter at breast height (DBH)) with evidence of primary excavator (e.g., woodpecker and flicker) activity.
2 The provincial benchmark is the highest capability habitat for a particular species in the province, against which all other habitats for that species are rated.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – EIA - 17 - January 2018
4.4.2.2 Great blue heron
Great blue heron has previously been noted as present at the site exhibiting foraging behavior. A search for nests (protected year-round by the BC Wildlife Act (Section 34)) was conducted. The nest search methods outlined in the “Ground Nest Search method in Inventory Methods for Raptors, Standards for Components of BC’s Biodiversity No. 11 (Ministry of Sustainable Resource Management 2001) was used.
Adaptations to the standard survey protocol were: a single nest search was undertaken due to the small survey area and lack of previous evidence of nesting, and a general area search was undertaken rather than searching based on other evidence of nesting. Trees were observed back-lit by the sky to highlight nests. The absence of leaves enhanced observability.
4.4.2.3 Oregon forestsnail
Survey methods were based on observational searches in the potentially-affected area for key habitat requisites as listed in the Recovery Strategy for the Oregon Forestsnail (Allogona townsendiana) in Canada (EC 2014). Targeted habitats for survey were identified as an intact deciduous and/or mixed forest or dense shrubland that maintains a moist ground environment, with coarse woody debris and stinging nettle (Urtica dioica) for feeding, mating, oviposition and shell maintenance. Ecosystems with big-leaved maple (Acer macrophylum) and stinging nettle are strong indicators of presence.
4.4.2.4 Pacific water shrew
A habitat suitability rating scheme (Table 3) developed by Gebauer and Associates and Hemmera was used to classify locations adjacent to, upstream, and downstream of, the proposed development area. Habitat at eight sites on watercourses adjacent to, upstream, and downstream of, the development area was rated according to four key characteristics for the species: watercourse features, riparian condition (esp. vegetation), coarse woody debris presence, and the presence of access and movement barriers. A four-class scale was used (high, moderate, low and nil).

5.0 EXISTING SITE CONDITIONS
This section provides the results of the desktop and field assessment activities, and describes relevant environmental resources and constraints that were identified. The proposed Project is located at the north end of the City of Surrey, partly within a Single Family Residential Zone and partly within the boundaries of Hawthorne Park, which is a designated community park. It also intersects two Sensitive Ecosystems Development Permit Areas: a Green Infrastructure Area, which includes the BC Hydro ROW and Hawthorne Park, and a Streamside Area, which includes Hawthorne and Bon Accord creeks (COSMOS 2017; Figure 3). The study area has been impacted or influenced to varying degrees by roadways and residential developments; however, remnant forest patches and riparian areas are present within the study area, and existing conditions support a range of habitats for fish, vegetation, and wildlife species. Evidence of human use, especially garbage, dumping, habitation and trampling is common. Early work on the development was apparent, including fencing and hand falling of some vegetation.
The study area is an early successional forest of black cottonwood (Populus balsamifera ssp. trichocarpa) with occasional coniferous elements of western hemlock (Tsuga heterophylla) and western redcedar (Thuja plicata). Red alder (Alnus rubra) and paper birch (Betula papyrifera) occurs in select locations. Many trees are tagged with identification labels. Trees are generally between 15 centimeters (cm) and 30 cm diameter- at-breast-height (visual estimate). The understory is dominated by Himalayan blackberry (Rubus armeniacus), baldhip rose (Rosa gymnocarpa), and salal (Gaultheria shallon), with sword fern (Polystichium munitum) and red huckleberry (Vaccinium parvifolium). Woody weeds such as holly (Ilex sp.), English ivy (Hedera helix) and various laurels (Laurus spp.) are locally common. Vertical complexity is low, and the canopy is generally open.
There are two watercourses in the study area, Hawthorne Creek and Bon Accord Creek. The watercourses are channelized, and are dominated by silt substrates with abundant leaf litter; except for Bon Accord Creek at the north end of Hawthorne Park, which has cobble and gravel substrates in a natural channel configuration. Hawthorne Creek is confluent with Bon Accord Creek in the north end of Hawthorne Park. Each creek has an artificial pond near the confluence. Downstream of the confluence, Bon Accord Creek flows north to the Fraser River.
5.1 FISH AND FISH HABITAT
Watercourses within the study area consist of Class C and B roadside ditches (on the west side of the study area), and two Class A streams flowing through Hawthorne Park (as per classification in Table 4; Figure 3). The Class C roadside ditches (located between King George Boulevard and 139 Street) lie within the Quibble Creek catchment, which drains south into the Serpentine River (COSMOS 2017). Hawthorne Creek, Bon Accord Creek and their respective tributaries lie within the Bon Accord catchment, which drains north to the Fraser River. Watercourses in the study area are listed in Table 4 and further described (from west to east) in sections below. In situ water quality collected during the survey is summarised in Section 4.1.2.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – EIA - 20 - January 2018
5.1.1 Class C Ditches
The Project intersects with Class C roadside ditches along 105A Avenue (between Whalley Boulevard and 138 Street), as well as at 138A Street and 139 Street (Figure 3); these ditches are not classified as fish habitat (per the federal Fisheries Act), and are not considered “streams” under the City of Surrey stream classification system. The ditches in and around the Project area were approximately 1 m in channel width; all had water (0.3 m to 0.5 m wetted width), with limited flow observed (Appendix C-1, Photo 1 and Photo 2). Substrate was dominated by fine sediment, with pockets of small gravel and organic materials (i.e., leaf litter); sections of the ditches were overgrown with grasses. Adjacent vegetation was limited to grass, with the occasional small shrub.
5.1.1.1 Unmapped Ditch
During site clearing, an unmapped ditch was discovered flowing north from a 300 mm pipe on the east side of 140B Street. A biologist examined the channel on January 13, 2018 to assess its potential value as fish habitat and assign a classification. The drainage channel width was approximately 0.75 m and extended approximately 140 m north from the culvert outlet. The channel gradient was low and the substrate present was predominantly organics (covered with leaf litter). The drainage was linear and aligned through a swale- type channel, suggesting an anthropogenic origin.
Flow within the drainage was discontinuous with only shallow areas (less than 10 cm) of pooling water observed. There was minimal evidence of scour observed. Evidence of flow decreased further to the north and the ditch ended approximately 5 m north of Hawthorne Creek (where it flows parallel to 106 Avenue). A perpendicular bank (approximately 1.0 m high) was observed at the end of the ditch that appeared to act as a barrier to prevent overland flow in the drainage from entering Hawthorne Creek.
No overland connection between the 140B Street Ditch and Hawthorne Creek was identified during the field assessment. This suggests that water in the drainage infiltrates to ground over the length of open channel. Based on these observations, using the City of Surrey’s watercourse classification system, the ditch would be classified as a Class C (green-coded) ditch, as it does not support fish and does not provide significant food and nutrient input to downstream fish habitat.

5.1.2 Hawthorne Creek and Tributary
Hawthorne Creek (unmapped in iMap BC) is a low gradient (0.5% to 1%), watercourse fed by discharge from municipal stormwater drainage mains along 140 Street (flowing from the south), and by a Class B ditch along the west side of 140B Street. It flows northeast and drains into Bon Accord Creek Ponds. A description of the Class B and Class A sections of this creek are provided below and shown in Figure 3.
5.1.2.1 Hawthorne Creek – BC Hydro Right of Way
This upstream-most section of Hawthorne Creek flows from the culvert outlet west of 140 Street east across the existing BC Hydro and FortisBC ROWs for approximately 75 m to 140B Street (Appendix C-1, Photo 3), at which point it turns north at the 105A Avenue alignment and connects to the Hawthorne Creek Tributary (Section 5.1.2.2) and Hawthorne Creek (Section 5.1.2.3) (Figure 3).
The average channel and wetted widths were 1.5 m and 0.9 m, respectively, with a bankfull depth of 0.5 m. Substrate was dominated by fine sediment (i.e., mainly silt) and organic debris (i.e., leaf litter). Vegetation within the ROW is actively managed; therefore, the riparian vegetation was limited to shrubs: possibly hardhack (Spiraea douglasii) and mowed Himalayan blackberry. A concrete culvert (0.60 m in diameter) was located at the pedestrian trail that runs along the ROW (Appendix C-1, Photo 4).
This section of channel is currently listed as a Class B watercourse (COSMOS 2017). Although no fish sampling was conducted during the survey and no fish were seen, the conditions observed along this section of the watercourse suggest a Class A classification, as no barriers to fish passage were observed upstream of Bon Accord Creek. Overall, the habitat value for fish associated with this section of Hawthorne Creek was considered low, as a result of limited (if any) spawning habitat, minimal structural or depth complexity present and minimal flow.
5.1.2.2 Hawthorne Creek –Tributary
This ditch is approximately 165 m long and is located between 140B Street and the FortisBC ROW. This ditch joins Hawthorne Creek where it turns north at approximately the 105A Avenue alignment (Figure 3).
Average channel and wetted widths were 1.5 m and 0.9 m, respectively, with a bankfull depth of 0.15 m (Appendix C-1, Photo 5). Substrate was dominated by fine sediment and organic debris. The channel was largely filled with emergent vegetation. The ditch narrows and becomes overgrown approximately 100 m upstream from its confluence with Hawthorne Creek. Riparian vegetation was limited to Himalayan blackberry on the left bank, and red alder (Alnus rubra), hardhack and Himalayan blackberry on the right bank. Abundant anthropogenic debris was observed along the channel. Limited flow was observed. Flow is likely dependent on overland drainage from the surrounding area.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 24 - January 2018
This tributary is classified as a Class B watercourse in COSMOS (2017). This classification was confirmed in the field. The fish habitat value (in terms of food and nutrient contribution) associated with this tributary was low. To assess and minimize potential impacts to this drainage, a 15 m riparian setback was assigned consistent with riparian BMPs.
5.1.2.3 Hawthorne Creek – North of 105A Avenue Alignment
This section of Hawthorne Creek flows north (from the 105A Avenue alignment) along the west side of 140B Street for 85 m before flowing east along the south side of 106 Avenue for approximately 270 m before discharging into Bon Accord Creek Ponds (Figure 3).
Average channel and wetted widths in this section of Hawthorne Creek were 3.7 m and 2.9 m, respectively, with a bankfull depth of 0.35 m and an average residual depth of 0.10 m (Appendix C-1, Photo 6 and Photo 7). Substrate was dominated by fine sediment and organic debris (i.e., leaf litter), with pockets of sand and small gravel in the vicinity of the culvert at 141 Street. Limited flow was observed. Limited cover (i.e., less than 5% of the channel; RISC 2001) was observed in terms of over-stream vegetation, small woody debris and undercut banks. Riparian vegetation consisted almost entirely of red alder (various stages of maturity) and shrubs. Seven culverts were observed along this section of Hawthorne Creek: all but one were on the left bank (contributing stormwater drainage from mains along 106 Avenue, and 141, 141A and 142 streets (Figure 3). Most of these culverts were concrete pipes (0.6 m in diameter) with concrete headwalls, and had limited flow at the time of the survey (Appendix C-1, Photo 8).
This section of Hawthorne Creek is identified as a Class A watercourse in COSMOS (2017). Fish species with the potential to be present in Hawthorne Creek are discussed in Section 4.1.1. No fish were observed; however, the apparent absence of any barriers to fish movement upstream to this section suggests the classification is appropriate. The habitat value to fish associated with this tributary was low as a result of limited spawning habitat, minimal structural or depth complexity present and limited flow.
5.1.3 Bon Accord Creek Ponds
Bon Accord Creek Ponds consist of two ponds, centrally located in Hawthorne Park (Figure 3; Appendix C-1, Photo 9, 10 and 11). One pond is located on Hawthorne Creek, immediately upstream of its confluence with Bon Accord Creek and the other is located immediately downstream of the confluence on Bon Accord Creek. Based on historical images dating back to August 1998, the two ponds appeared dry until 2001 (Google Earth 2017); they were constructed in 1999 and are classified as detention ponds (COS 2017).
Water flows from the west pond into the east pond via two 1,200 mm corrugated metal pipes or CMPs (COSMOS 2017; Figure 3), and then north through a trash gate located at the outlet of the easternmost pond to Bon Accord Creek. According to COSMOS, the west and east ponds have an area of approximately 2,500 m2 and 5,300 m2, respectively.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 25 - January 2018
There are no documented records of fish presence in Bon Accord Creek Ponds (iMap BC 2017); however, a local resident encountered during the survey mentioned he had caught (via angling) coastal cutthroat trout (Oncorhynchus clarkii clarkii), carp (Cyprinus sp.) and black catfish (Ameiuru melas) in the east pond. He also mentioned seeing threespine stickleback (Gasterosteus aculeatus) and goldfish (Carassius auratus) in the pond.
In the absence of information to the contrary, Bon Accord Creek Ponds are considered fish-bearing, consistent with the COSMOS (2017) classification (Class A). Provided the water quality remains acceptable, the two ponds likely provide rearing and over-wintering habitats for salmonids. The ponds likely represent low to moderate value fish habitat, based on the observed characteristics (pond depths were not assessed). The November 2017 fish sampling survey of Bon Accord Creek and ponds resulted in the capture of 154 three-spine stickleback (Gasterosteus aculeatus), with the greatest concentration captured in Bon Accord Creek Ponds. No other fish species were captured
5.1.4 Bon Accord Creek and Tributary
Bon Accord Creek (un-gazetted watercourse; WC 100-024200) is classified as a Class A fish habitat (COS 2017). This low gradient (0.5% to 1%) creek begins at 104 Avenue; it is fed by water flowing north through municipal stormwater drainage mains along 104 Avenue, and a storm main that flows underneath Hawthorne Park and joins the creek at the south path crossing (Figure 3). It crosses 108 Avenue through a 900 mm closed bottom, unembedded concrete culvert. The culvert is approximately 20 m long and has a slope of approximately 2.5%. The creek flows north approximately 330 m through Hawthorne Park before it drains into Bon Accord Creek Ponds, then continues north for approximately 3 km before joining the Fraser River.
5.1.4.1 Bon Accord Creek - Upstream Reach
The upstream reach of Bon Accord Creek (i.e., upstream, or south of Bon Accord Creek Ponds) is approximately 330 m long (to 104 Avenue) (Figure 3; Appendix C-1, Photo 12 and Photo 13). Two trails currently intersect this reach: one approximately 20 m upstream of the ponds (crossing consists of a wooden bridge); and the second is 150 m upstream of the ponds (crossing consists of a 1400 mm CMP). A drainage pipe and retention wall were located on the creek’s right bank, approximately 160 m upstream of the ponds.
Average channel and wetted widths in this reach were 3.7 m and 2.4 m, respectively, with a bankfull depth of 0.57 m and average residual depth of 0.24 m. Substrate was dominated by fine sediment (mainly silt) and organic debris (i.e., leaf litter), with pockets of sand in the upper 100 m of the creek. Limited flow was observed, along with an orange residue from iron precipitate (likely indicating buried organics nearby) and residue on the water surface (Appendix C-1, Photo 14). Moderate cover (i.e., 5% to 20% of the channel; RISC 2001) was provided mainly by over-stream vegetation and small woody debris, with occasional undercut banks and deep pools. Riparian vegetation consisted primarily of red alder (various stages of maturity), shrubs and ferns, with a few conifers.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 26 - January 2018
No fish were observed during the survey of Bon Accord Creek, and no record of fish presence was available in the vicinity of the study area. Coastal cutthroat trout, coho salmon (O. kisutch) and threespine stickleback have been documented within the lower 500 m of Bon Accord and East Bon Accord creeks (iMap BC 2017). A coastal cutthroat trout was also observed in 1994 at a location approximately 2 km north of the Project site; no other formal record of fish presence was identified. Three obstacles (not necessarily barriers) to fish passage have been documented in the past: two culverts (at 800 m and 1.2 km upstream of the creek’s mouth), and a dam (at 1 km upstream of the mouth).
In the absence of information to the contrary, based on the COSMOS classification and the anecdotal report provided by a local resident (Section 5.1.3), the section of Bon Accord Creek in the study area is considered potentially fish-bearing; therefore, the current Class A status was maintained for this report. The culvert at 108 Avenue is unlikely to present a barrier to fish movement; however, it may present an obstacle if the trash rack is filled with debris. Juvenile fish and small resident fish may also not be able to pass upstream through the culvert during high velocity flows. Overall, this surveyed reach of Bon Accord Creek represented moderate value fish habitat, with no observed spawning gravel, high occurrence of fine sediment, and limited flow, but also with some deep pools and moderate cover and complexity.
5.1.4.2 Bon Accord Creek Tributary
This drainage ditch is approximately 120 m long and is located along the south boundary of Hawthorne Park. This tributary joins Bon Accord Creek approximately 90 m north of 104 Avenue (Figure 3). Average channel and wetted widths were 1.4 m and 0.75 m, respectively, with a bankfull depth of 0.15 m (Appendix C-1, Photo 15). Substrate was dominated by fine sediment and organic debris. Limited flow was observed at the time of the survey, and iron precipitate was noted. Riparian vegetation consisted mainly of Himalayan blackberry and red alder.
There was no evidence to dispute the current Class A designation for this watercourse; although, the habitat value to fish was determined to be low, as a result of the lack of complexity and limited flow. To assess and minimize potential impacts to this drainage, a 5 m riparian setback was assigned consistent with riparian BMPs.
5.1.4.3 Bon Accord Creek - Downstream Reach
This section of Bon Accord Creek is downstream (or north) of the outfall from Bon Accord Creek Ponds approximately 3 km north of its confluence with the Fraser River (Figure 3). Only the upstream-most 50 m of this section were surveyed for this assessment. A park trail crosses over the creek at the outlet of Bon Accord Creek Pond East via a wooden bridge (Appendix C-1, Photo 16). A debris rack and concrete apron form part of the bridge structure and may represent an obstacle to fish passage during low flows periods (Appendix C-1, Photo 16 and Photo 17).
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 27 - January 2018
Average channel and wetted widths in the downstream reach were 3.7 m and 3.4 m, respectively, with a bankfull depth of 0.40 m and average residual depth of 0.16 m (Appendix C-1, Photo 18). Substrate was dominated by fine sediment and organic debris. Limited flow was observed. Moderate cover was provided mainly by over-stream vegetation and small woody debris, with the occasional large woody debris. Riparian vegetation consisted mainly in red alders (various stages), shrubs and a few western redcedar.
Overall, this surveyed reach of Bon Accord Creek represented “moderate” value fish habitat, with limited observed spawning gravel, high occurrence of fine sediment, and low water levels, but also with some deep pools and moderate cover and complexity. To assess and minimize potential impacts to this drainage, a 10 m riparian setback was assigned consistent with riparian BMPs.
5.1.5 In Situ Water Quality
In situ water quality measurements were collected at various (representative) sites throughout the study area (Table 5). Temperature, pH, conductivity, and dissolved oxygen values were similar among sites. All temperature, pH and dissolved oxygen values fell within their respective range of recommended values for the protection of freshwater life (CCME, 2007; MoE, 2017).

5.2 VEGETATION
The study area is located in the Coastal Western Hemlock Very Dry Maritime Eastern subzone (CWHxm1) (Pojar, Klinka, and Demarchi 1991). Much of the study area is comprised of municipal park and residential areas. Vegetated areas within the residential areas are comprised mainly of lawns, gardens, and street trees. The Project intersects vegetated areas in the BC Hydro ROW and Hawthorne Park.
The BC Hydro ROW (Green Infrastructure Area) is comprised mainly of grasses and low shrubs, which are likely regularly maintained as part of an ongoing vegetation maintenance program. A paved walking path runs the length of the ROW. The ROW is immediately adjacent to Hawthorne Park (Appendix C-2, Photo 1).
Hawthorne Park represents a remnant patch of young, second growth, deciduous forest. Vegetation within the park is representative of rich, moist soils, and young, second-growth deciduous and mixed forest. The north and west portions of the park are deciduous-dominated with a dense understorey of shrubs (Appendix C-2, Photo 2 and 3). The southern portion of the park has a mixed forest with alder, cottonwood, western hemlock, and occasional western redcedar and Douglas-fir (Pseudotsuga menziesii) (Appendix C-2, Photo 4). Understory in these forested areas is a mix of native shrub species including salmonberry (Rubus spectabilis), thimbleberry (R. parviflorus), red huckleberry, sword fern, and hardhack.
Several weedy and invasive herbaceous species are also present in the study area including Himalayan blackberry, cherry laurel (Prunus laurocerasus), reed canary grass (Phalaris arundinaceae); and buttercup (Ranunculus sp.).
Two vegetated peatland ecosystems were identified in the location of the proposed habitat feature, south of the existing parking lot and picnic area: lodgepole pine / peat-mosses (CWHdm/11) and western redcedar – Sitka spruce / skunk cabbage (CWHdm/12) (Figure 1). As described by Mackenzie and Moran (2004), lodgepole pine / peat-mosses ecosystems occur on level terrain or topographic depressions at elevations below 100 m. In undisturbed “natural” ecosystems, these sites are slightly domed and raised above surrounding sites through the active growth of Sphagnum, with vegetation dominated by dwarf shrubs and a rich moss layer. Similarly, Western redcedar – Sitka spruce / skunk cabbage ecosystems occur on floodplains and receiving sites such as toe of slopes and wetland margins. Typical sites are strongly mounded with conifers on elevated microsites; the canopy consists primarily of western redcedar and western hemlock with salal, salmonberry, and red huckleberry dominating the shrub layer.
Although the vegetated areas in the location of the proposed habitat feature have been classified as lodgepole pine / peat-mosses and western redcedar – Sitka spruce / skunk cabbage ecosystems, the plant community compositions are not clearly reflective of these classifications. Currently, the lodgepole pine / peat-mosses ecosystem (Figure 4) is dominated by a dense tree layer; western redcedar dominates with a lesser component of western hemlock and paper birch. The shrub and herb layers are sparse; salal, red
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 29 - January 2018 huckleberry, false lily-of-the-valley (Maianthemum dilatatum), and bracken fern (Pteredium aquilinum) were documented. The presence of some bog indicator species and a thick fibric organic layer are indicative of the ecosystem classification. In addition, the understorey of this area is heavily impacted by human activity.
An encampment was noted, and the presence of trails, garbage, and trampled vegetation indicates that people often use the area.
The western redcedar – Sitka spruce / skunk cabbage ecosystem (Figure 4) exhibits a more open canopy. The tree layer is predominantly western hemlock with a minor component of paper birch. The shrub layer is pronounced and composed primarily of salmonberry, with a lesser component of red huckleberry, salal, red elderberry (Sambucus racemosa), beaked hazelnut (Corylus cornuta), and hardhack. Lady fern (Athyrium filix-femina), sword fern, and trailing blackberry (Rubus ursinus) were noted in the shrub layer. The open canopy and the dominant shrub layer were indicative of the ecosystem classification. The thick layer of salmonberry prevents access and possible damage by people.
In addition to historical disturbance (e.g., fill placement for the picnic area and current parking lot), an arborist report conducted for the Project (Diamond Head 2017) identified poor, shallow root depth of trees due to the presence of a very high water table. As a result, a significant number of trees in Hawthorne Park, and specifically in the area of the proposed habitat feature are in poor overall health (Diamond Head 2017).

5.3 SOIL
Geotechnical test holes dug within Hawthorne Park generally encountered sandy / gravelly fill over a sequence of soft peat / soft clayey silt and underlain by dense silty sand (i.e., compact sand with some gravel fill to the depths of 1.4 m to 2.4 m, peat to the depths of 2.3 m to 5.2 m, and silt to the depths of 4.0 m to 8.8 m) (Braun Geotechnical 2017). It is this compact material, coupled with the high water table, that prevents trees from thriving.
5.4 BOG HABITAT
The presence of peaty soils in the boreholes indicates that there was likely a functioning peat bog present in the past. However, historical and current disturbances have impacted the health of the ecosystem and vegetation communities. The presence of fill material covering the bog negatively impacts the ability of the peat to retain water, which is a key function of a bog ecosystem. Development within and surrounding the park has altered soil characteristics and hydrology, resulting in a transition of the vegetation community from bog indicator species to species more indicative of drier, upland ecosystems. As such, the ecosystems are not functioning as they would in their pristine form. In addition, as stated above, the trees on site are in poor health due to the presence of compact materials and high water table.
5.5 WILDLIFE AND WILDLIFE HABITAT
Commercial, residential and park development have removed much of the historic tree cover within the study area, replacing it with grasses and shrubs. Nevertheless, the ecosystems within Hawthorne Park represent potential habitat for a variety of wildlife species. Hawthorne Park is connected to the BC Hydro ROW Green Infrastructure Network (GIN) corridor #98, a feature that provides contiguous habitat connectivity for wildlife movement and seed dispersal between hubs (intact sites of naturally-functioning ecosystems) and other parts of the GIN. The corridor been assigned an ecological value of “moderate” by the City of Surrey (COS 2017), and connects Hawthorne Park to Green Timbers Park to the south and Invergarry Park to the north. Habitat values associated with the study area for birds, mammals, and amphibians/reptiles are discussed below.
5.5.1 Birds
Suitable songbird nesting habitat is available throughout the forested areas of the study area, as well as in several of the hedges and ornamental trees found on nearby residential properties. Several songbirds were observed including American robin (Turdus migratorius), dark-eyed junco (Junco hyemalis), song sparrow (Melospiza melodia), Pacific wren (Troglodytes pacificus), golden-crowned kinglet (Regulus satrapa), red- breasted nuthatch (Sitta canadensis), hairy woodpecker (Leuconotopicus villosus), spotted towhee (Pipilo maculatus), and black-capped chickadee (Poecile atricapillus). The BC Hydro ROW represents suitable foraging habitat for several species of birds, including raptors such as owls and hawks, which may hunt for small mammals along the ROW. No bald eagle (Haliacetus leucocepehalus) or osprey (Pandion haliaetus)
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 32 - January 2018 nests are recorded by the WiTS (2017) within the study area, however a large stick nest, likely a red-tailed hawk (Buteo jamaicensis), was noted on the west side of the park at the north end of 104 B Street within a cottonwood tree (Figure 5, Appendix C-2, photo 5). A single great blue heron, Mallard ducks (Anas platyrhynchos), a pair of hooded mergansers (Lophodytes cucullatus) were observed utilizing the Bon Accord Creek Ponds in February 2017 (Appendix C-1, Photo 9).
Location of red-tailed hawk nest
Figure 5 Location of Stick Nest
Qualified Environmental Professionals (i.e., a Registered Professional Biologist) visited the study area and concluded that there are no nests present for bald eagle, great blue heron or osprey and the prescribed mitigation (clearing prior to accepted breeding periods (GOC 2018)) avoids any other violation of 34(a) and 34(c). Furthermore, the Project is not within the breeding range, or lacks breeding habitat, for other species specifically referenced in Section 34 (b) (i.e., peregrine falcon, burrowing owl or gyrfalcon).
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 33 - January 2018
5.5.2 Mammals
Given the presence of residential land use within the study area, the mammal species present are likely to be common and widespread species suited to developed habitats, including, small rodents, bats, raccoons (Procyon lotor), black-tailed deer (Odocoileus hemionus columbianus), and coyotes (Canis latrans). No wildlife sign was noted in the study area.
5.5.3 Amphibians and Reptiles
Outside of the breeding season (early spring to early summer), amphibians (including frogs, toads, and salamanders) have potential to occur within wooded areas and riparian areas associated with watercourses in the study area. Beyond the watercourses, the forest in the park, including the remnant bog area, is likely too dry and trampled (from human activity) to support high levels of use by amphibians. Suitable breeding habitat for aquatic-breeding amphibians within the study area is limited to the ponds on Bon Accord Creek in the centre of the park, and potentially slow-moving sections of watercourses in the study area. Invasive species such as bullfrog (Rana catesbeiana) and green frog (R. clamitans) species, which are both considered to be tolerant of human disturbance and low water quality, may be present in several of the ditches within the study area when wetted. Native species such as northern Pacific chorus frog (Pseudacris regilla) may also breed in the ponds and some of the wider ditch areas. Northern red-legged frogs and western toad have low to moderate potential to breed in the ponds in the park (Table 5).
Reptiles that have potential to occur on-site include garter snakes (Thamnophis spp.), which may use open habitat and grassy areas in the ROW for basking. Red-eared sliders (Trachemys scripta elegans) and western painted turtles (Chrysemys picta) may potentially occur in the ponds along Bon Accord Creek.
5.6 SPECIES AT RISK
Based on data available from iMap (2017) no species at risk have been recorded within 1 km of the study area. A masked occurrence is noted overlapping with the study area. A request for record specific data was submitted to the CDC; however, neither the species recorded in the occurrence nor suitable habitat overlaps with the study area.
Several fish and wildlife species at risk have the potential to occur in or in close proximity to the study area, including one species of fish, seven species of birds, two species of mammals, two species of amphibian and one species of reptile. These species, along with the likelihood of their anticipated potential to occur in the study area, are presented below in Table 6.

6.0 ASSESSMENT OF PROJECT EFFECTS
6.1 IDENTIFICATION OF POTENTIAL PROJECT EFFECTS
This section identifies and describes potential impacts on the identified environmental components that may result from the proposed Project, including its construction and subsequent operational phases.
For the purposes of this EIA, the identification and assessment of potential impacts and residual effects on fish and fish habitat constitutes an Assisted Assessment, as defined by DFO, to determine whether the Project will result in serious harm to fish that form part of a CRA fishery, consistent with provisions in the federal Fisheries Act (see Section 9.1). A determination is also provided related to potential effects on identified species at risk.
6.1.1 Fish and Fish Habitat
Pathways of Effects (PoEs) for construction activities have been defined by DFO and can be used when conducting a Self-Assessment under the Fisheries Act to evaluate project-related activities with respect to the type of cause-effect relationships that are known to exist and the mechanisms by which stressors can ultimately lead to effects on fish and fish habitat (DFO 2014). This section describes effects that may occur as a result of Project activities that have the potential to affect fish and fish habitat, previously referenced in Section 2.0.
The majority of the Project’s potential effects, prior to implementation of mitigation, are associated with watercourse crossings, land-based construction activities (e.g., use of industrial equipment near watercourses, clearing of riparian vegetation, and grading) in relation to the 105A Avenue widening and new road construction.
Table 7 provides a summary of potential effects for the Project activities; “rows” list the DFO activities that are anticipated to occur as part of the proposed Project and may initiate a pathway of effects, while “columns” indicate the ultimate adverse effects to fish and fish habitat.

O: Activity is anticipated to occur during the operation phase. N/A: Pathway of effect is not considered applicable to this Project.
6.1.1.1 Changes in Surface Water Quality
Water quality in the watercourses in and around Hawthorne Park was assessed to be within acceptable parameters to sustain fish. Construction activities have the potential to release sediment-laden water into the watercourses (Class A, B, or C) identified within the study area. Construction and operation also has the potential to increase bank erosion. When present in fish-bearing waters, sediment can impact water quality and negatively affect fish by decreasing visibility, damaging fish gills, and reducing habitat quality through benthic smothering. The use of construction equipment near watercourses also increases the potential for release of contaminants into the aquatic environment resulting from accidental spills, which have the potential to cause fish mortality, alterations in growth or reproductive success, and modification of instream habitat values.
Impacts to water quality could also be experienced during the operational phase of the Project as a result of increased stormwater runoff from the increased impervious surface (i.e., replacing vegetated areas) associated with the widened and new roads. Increased vehicle traffic near watercourses also increases the risk of incidental introduction of contaminants (e.g., polycyclic aromatic hydrocarbons; PAHs) and sediment mobilization. Increased hydrological input from the off-channel habitat feature may also impact water quality in Bon Accord Creek.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 38 - January 2018
6.1.1.2 Alteration of Instream and Riparian Habitat
The deposition of eroded soil (i.e., introduced through infilling and construction of new ditches and grading/excavation activities adjacent to watercourses) can affect the capacity for fish and aquatic organisms to disperse through watercourses within the study area by restricting habitat connectivity and opportunities for fish to use and move between existing aquatic environments. This effect is most relevant for activities occurring within or immediately adjacent to fish-bearing watercourses (i.e., Hawthorne and Bon Accord creeks). Removal of instream and riparian vegetation within the Class A or B watercourses can reduce channel stability, shade, biofiltration capacity and food and nutrients available for transport downstream. Class C ditches do not contribute to fish habitat; therefore, any loss or alteration of these ditches is not anticipated to have any effect on fish habitat values associated with the study area.
Instream Habitat
Approximately 89 m2 of Class A instream habitat3 on Bon Accord Creek and 244 m2 of Class B habitat on the tributary to Hawthorne Creek will be permanently altered by the proposed Project (Figure 6).
Riparian Habitat
Approximately 1,620 m2 of riparian habitat5 will be displaced by construction of the new road. Of this, 1,140 m2 will be impacted on Hawthorne Creek and the Tributary to Hawthorne Creek and 480 m2 will be impacted on Bon Accord Creek. Much of the existing riparian area is already impacted by vegetation management activities, invasive species, and human disturbance.
3 Average channel width = 3.7 m, width of proposed road = 24 m 4 Average channel width = 1 m, width of proposed road = 24 m 5 Based on a proposed road width of 24 m and default riparian setback of 10 m measured from top of bank,

6.1.1.3 Changes in Water Temperatures / Thermal Cues
Clearing of riparian vegetation adjacent to watercourses could potentially result in changes to water temperatures (i.e., higher temperatures resulting from reduced vegetative cover and increased sun exposure). If resulting changes in water temperature are experienced in fish-bearing watercourses downstream of the study area, effects to fish and fish habitat could include depletion of dissolved oxygen, changes in the timing of reproductive behavior, and reduced reproductive activity or even mortality of fish.
6.1.1.4 Changes in Nutrient Concentrations, Food Supply
Clearing/removal of instream and riparian vegetation from Class A and B watercourses has the potential to result in changes to the quantity and composition of food and nutrient supply within the watercourses, potentially as a result of decreased input of organic materials and terrestrial insects to downstream fish habitats.
6.1.1.5 Incidental Injury or Mortality of Fish
Displacement or stranding of fish could occur in Class A ditches if construction requires dewatering or results in dramatic changes in flow patterns of upstream ditches. Direct injury or mortality of fish (including eggs, ova, and larvae) may result from physical disruption from industrial equipment in fish-bearing watercourses (DFO 2014). For example, fish eggs and/or larvae may be crushed by equipment entering a stream, or juvenile fish may be trapped during the placement of a new culvert, or riprap placement for bank protection.
6.1.2 Vegetation
The Project will impact approximately 9,720 m2 of terrestrial vegetation in the southern portion of Hawthorne Park. Terrestrial vegetation and ecosystems in this area are second-growth, less than 80 years old. At the west side of the park, immediately adjacent to the BC Hydro ROW, trees are predominantly red alder and black cottonwood. Where the road alignment turns further south at 142 Street, it bisects a section of mixed forest with western hemlock, western redcedar, Douglas-fir, red alder, and black cottonwood. No old-growth forests or wetlands will be impacted by the Project; however, there is potential for introduction of invasive plant species to the park through vehicle and machinery movement.
6.1.3 Wildlife and Wildlife Habitat
6.1.3.1 Sensory Disturbance
Sensory disturbance to wildlife includes auditory, olfactory, and visual disturbances including noise from heavy equipment operation and vegetation clearing, odors of fuels and humans, and the presence and movement of equipment and personnel. Some of these effects may also occur during the operational phase of the Project (e.g., auditory, olfactory, and visual disturbance from increased traffic on the widened road).
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 41 - January 2018
Reactions of wildlife to sensory disturbance tend to vary between species and individuals, with effects ranging from undetectable increases in stress to movement away from the disturbance. As the Project will be undertaken within an established urban setting with pedestrian traffic and use of 104A Avenue by many large, commercial transport vehicles as well as normal vehicular traffic, the Project is not expected to result in increased sensory disturbance to wildlife.
6.1.3.2 Habitat Loss and Alteration
Wildlife habitat loss resulting from the Project will impact roadside and ROW habitat that primarily consists of grasses and low-lying vegetation, which is considered low value wildlife habitat, as well as second-growth forest within Hawthorne Park, which is considered to be “moderate” value wildlife habitat (mainly due to existing disturbance by human activity). Wildlife habitat is limited to common urban and suburban species accustomed to human presence. Vegetation removal (including removal of trees and clearing of shrubs/grasses) and the alteration of riparian habitat will occur in the vicinity of the Project footprint as part of construction activities. Wildlife movement away from the study area during the construction phase, as a result of sensory disturbance (displacement), may also occur temporarily. The operations phase of the Project may impact wildlife that uses the park, specifically deer, coyotes, and small mammals. Property acquisition will result in restoration and enhancement opportunities (Section 8.1).
6.1.3.3 Mortality or Injury
Wildlife mortality or injury may occur as a result of vegetation clearing and construction activities within the construction footprint. Birds, small mammals, and amphibians are most susceptible to these activities, without appropriate mitigation to reduce risk (Section 8.1). Increased vehicular traffic on the widened road also has the potential to result in injuries or mortalities (i.e., “road kills”) during the operational lifespan of the Project.
6.1.4 Species at Risk
Species at risk with potential to occur on site (see Table 6) are discussed below. Potential effects on coastal cutthroat trout habitat (the only at-risk fish species considered to have potential to be present) are outlined in Section 6.1.1. As described for wildlife in Section 6.1.3 above, Project construction and subsequent road operation have the potential to negatively affect terrestrial wildlife species at risk through sensory disturbance, habitat alteration and/or loss, and mortality or injury. The majority of the terrestrial wildlife species at risk with moderate-to high potential to occur on site are anticipated to use the study area primarily for foraging (see Table 6). Exceptions to this include specific bird, bat, and amphibian species (as described below).
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 42 - January 2018
6.1.4.1 Birds
Great blue heron (fannini subspecies) is distributed along the coast of BC, with a relatively small population concentrated at a few breeding colonies in southern BC (COSEWIC 2008b). This species forages for its prey in a variety of aquatic habitats, including stream channels, marshes, and roadside ditches. Great blue heron typically nest in large colonies, within 2.9 km to10 km from foraging areas (COSEWIC 2008b). A nesting colony is recorded by the BC CDC (2017) in Colony Farm Regional Park near on the east side of the Coquitlam River, approximately 4 km northeast of the Project area. No stick nests of great blue heron were observed in the potential development area. This species is determined to have low potential for nesting in the study area.
Rough-legged hawk spend the summer in the tundra, but may be found in winter months in southern Canada and the United States (Bechard and Swem 2002). Preferred habitat is open area, including marshes and grasslands, although they may hunt from utility poles, trees, and fence posts (Bechard and Swem 2002). This species has moderate potential to forage in the open area of the BC Hydro ROW and grassy areas of Hawthorne Park.
Common nighthawk may be found in urban and rural habitats, requiring open ground or clearings for nesting (EC 2016) and commonly nest on flat, gravel roofs in urban areas (Brigham, Ng, Poulin and Grindal 2011). They forage for flying insects in open forests, grasslands, and clearings (EC 2016, Brigham, Ng, Poulin and Grindal 2011). Artificial lighting may be advantageous for this species as it increases the number of flying insects available as prey (EC 2016). The potential for this species to nest in the study area is low.
Olive-sided flycatchers can be found on their breeding grounds throughout most of Canada between the months of April to August (EC 2016a). They are most often found in forest openings with tall trees for perching, such as natural forest openings and forest edges near rivers (EC 2016a). This species has been reported several times within the last ten years in parks within urban areas, including Tynehead Park. However, it is considered low potential for this species to construct nests in trees within the study area as few mature trees exist. If nests are present within the study area, these birds could be subject to sensory disturbance and habitat alteration during construction during the breeding bird window.
Barn swallow, which may utilize nearby buildings for nesting or roosting may potentially use the study area for forging. No buildings will be impacted by the Project activities; therefore, no negative impacts on these species are anticipated. The study area will be impacted by the road improvements; however, sufficient habitat for foraging exists to the north and south of the study area to mitigate this potential impact.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 43 - January 2018
Western screech owl is a secondary cavity nester found in lower elevation forested and treed environments (COSEWIC 2012b), and has been previously documented within riparian corridors in the Lower Mainland (e.g., RESL 2006, Hemmera 2015). This species has experienced rapid population declines in urban areas of the Lower Mainland, due largely in part to habitat loss and depredation by barred owl (Strix varia). This species was previously detected in Bear Creek and Green Timbers parks between 1995 and 1997 (Hemmera 2015); however, potential for occurrence within the relatively small riparian corridors within the study area is considered low. The cavity tree search did not result in identification of suitable cavity nest trees.
Band-tailed pigeon nest in pairs in forest edges and openings in forests and urban areas from sea level to mid-elevations (COSEWIC 2008a). This species forages in areas with flowering and berry-producing shrubs and trees (COSEWIC 2008a). Several recent sightings of band-tailed pigeon have been reported within parks and urban areas of the Lower Mainland (e-Bird 2017). This species is considered to have high potential to use riparian and upland terrestrial habitat within the study area for foraging purposes only.
Barn owl inhabit open grassland and agricultural areas where they forage on small mammals, primarily Townsend’s vole (Microtus townsendii) (Andrusiak 1994, Marti 1994, Taylor 1994, CDC 2017). They may also use residential and industrial-dominated landscapes (Hindmarch and Elliot 2014) if undisturbed grassland with abundant small mammals and nest sites, such as abandoned buildings, exist. No suitable nest sites were observed in Hawthorne Park; however, barn owls may use the open grassy areas for foraging. This species has a moderate potential for foraging in the study area.
6.1.4.2 Mammals
Townsend’s big-eared bat require extremely dark daytime roosting sites, such as caves, rock crevices, abandoned mines, and buildings. Nighttime roosts are building, caves, and mines. Townsend’s big-eared bats forage in pastures, old fields, road corridors and low elevation open forests (Lausen, Nagorsen, Hobbs, and Brigham 2016). There is low potential for this species to roost in neighbouring buildings adjacent to the park.
Little brown myotis is a relatively widespread bat species that was recently added to Schedule 1 of SARA as a result of dramatic population declines resulting from white-nose syndrome (a fungal disease) in eastern Canada (EC 2015). This species utilizes a variety of habitats for roosting, including man-made structures (e.g., buildings), tree cavities, and crevices in tree bark (EC 2015). Foraging takes place nocturnally, generally in open habitats such as ponds, roads, and open canopy forests (EC 2015). It is expected that this species has moderate potential to use the habitat within the study area.
Pacific water shrew require riparian habitats associated with permanent streams and wetlands with dense cover, generally in coniferous forests but may also be found in open, deciduous forests (EC 2014). Coarse woody debris is an important feature of suitable Pacific water shrew habitat (EC 2104). Critical Habitat has been defined for Pacific water shrew, but none has been mapped in Hawthorne Park (EC 2014).
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 44 - January 2018
Detailed habitat surveys were conducted as part of the species at risk impact assessment for Pacific water shrew. Eight sites were evaluated to understand and describe the habitat requisites for Pacific water shrew (Table 8, Figure 7). Sites were chosen based on the presence of a watercourse or water feature in the study area, or locations upstream or downstream of the study area.
The riparian ground cover was dominated by Himalayan blackberry and was generally open and unsuitable for Pacific water shrew. Canopy cover is structural stage 3 to 4, but structural stage 5 in the north of the park where Bon Accord Creek exits under 108 Street. The canopy, especially cottonwoods, provide much leaf litter, which dominates in-water and riparian substrates. The dominant sediment (overlain by leaf litter) is mud, except cobbles and gravel in Bon Accord Creek in the north end of the park. Coarse woody debris, while locally common in the forest areas is generally depauperate in the riparian areas, or only in small or large size classes. Nowhere in the riparian areas of the park is coarse woody debris abundant in all size classes.

Connectivity along watercourses, and between riparian and water features within the park and study area is generally good. Culverts, especially with high inverts and the trash racks and weirs on Bon Accord Creek can represent barriers to Pacific water shrew transit along watercourses. Trails criss-cross the park, but are likely less of a barrier than the substantial barriers identified at 108 and 104 streets and the Bon Accord Creek Ponds outlet to Bon Accord Creek.

6.1.4.3 Amphibians and Reptiles
Northern red-legged frogs require slow-moving streams, marshes, or bogs with at least 50 cm of water in which to breed (Ovaska and Sopuck 2004). Adults prefer mature, deciduous forest with abundant leaf litter and fallen logs. Adult forms of northern red-legged frog inhabit a variety of forest types, but occurs most often in older, damp forest stands (COSEWIC 2004). Eggs of northern red-legged frog hatch in late- spring and metamorphosis occurs between July and August (COSEWIC 2004).
Western toads also require aquatic habitat to lay eggs from early March to mid-May; however, they will use a wider range of breeding habitat, including roadside ditches (COSEWIC 2012). Tadpoles undergo metamorphosis and emerge from breeding sites in large numbers (thousands) from June to September, depending on annual weather conditions (Zevit 2010b). Adult toads are primarily terrestrial. Within BC, western toad occurs in a variety of aquatic and terrestrial habitats, including all forest and woodland types up to 3,000 m above mean sea level (CDC 2017). During the non-breeding (terrestrial) phase of the species’ life-cycle, western toad generally frequent riparian areas and/or moist forested upland habitats including forested meadows and open mature broadleaf and coniferous forested ecosystems (COSEWIC 2012a).
Both amphibian species noted above breed in early-spring in a variety of aquatic habitats, including watercourses within developed areas (COSEWIC 2004, 2012). Breeding habitat for both is considered limited within the study area; however, adults are considered to have moderate potential to occur in riparian habitat along ditches, creeks, and the ponds in the park. If present within the study area, these amphibians could be subject to sensory disturbance, habitat alteration, and mortality/injury as a result of construction activities. Increased vehicular traffic on the widened road also presents potential for increased risk of mortality/injury during the operations phase of the Project.
Western painted turtle use shallow lentic habitats including ponds, marshes, and slow-flowing reaches of streams and rivers (COSEWIC 2006b). Important habitat features include muddy substrates, abundant aquatic vegetation, and basking sites. This species is known to occur within urban settings in the Lower Mainland, and has been documented in Mundy Lake, Colony Farm Regional Park, and in a ditch on the south side of the Trans-Canada Highway near United Boulevard (the latter occurrence is now considered extirpated) (CDC 2017). Breeding takes place in early summer, and nests are generally constructed in upland areas (up to 350 m from a watercourse) with southern exposure and loamy soils with sparse vegetation (WPTRT 2016). Foraging takes place in slow-moving waterbodies in temperatures above 15°C (WPTRT 2016). This species is considered to have moderate potential to occur outside the study area in the Bon Accord Creek Ponds.

6.1.4.4 Invertebrates
Oregon forestsnail is an at-risk land snail species found in the southern coast of BC in deciduous or mixed- wood forest. This species is commonly associated with stands of bigleaf maple, western redcedar, red alder, salmonberry, and stinging nettle, but can also be found in edge habitats (i.e., roads, trails, and landscaped areas) in close proximity to vegetative cover (Zevit et al. 2012, EC 2016b). Important habitat features for this species also include: high soil moisture, presence of coarse woody debris, and leaf litter (EC 2016). This species has been documented within Colony Farm Regional Park, approximately 4 km northeast of the study area and across the Fraser River (BC CDC 2017). Critical habitat has been defined for Oregon forestsnail (EC 2016). An area that contains critical habitat for Oregon forestsnail has been defined within Colony Farm Regional Park (EC 2016b), but this area does not overlap with the study area.
The study area, in general, is characterised as a moist rich site in winter. However, the largely open canopy, and general rarity of plants of moist habitats in the site series (CWHxm/12) such as red alder, skunk cabbage (Lysichitum americanum) and lady fern (Athyrium filix-femina) suggests a summer-dry condition less than which is suitable for Oregon forestsnail. Big-leaf maple, a conspicuous species due to over-large leaves and drooping multi-stemmed trunks, and an indicator species for Oregon forestsnail, was not observed to occur in the study area. Stinging nettle was not observed during the site visits. Potential for Oregon forestsnail to occur in the study area is low.
Monarch breeding relies solely on milkweed species; however, monarchs will use a variety of plant species, including goldenrods (Solidago sp,) and asters (Aster sp.) (EC 2013), which may be present in open areas of the park. Western populations of monarchs overwinter from California to Mexico, and generally arrive in Canada by June (EC 2013). Although the presence of suitable breeding or nectaring plant species could not be determined during field studies, only two known occurrences of monarchs have been recorded in the Lower Mainland: one in Richmond, BC and one near Yale, BC in 2012 (BC Butterfly Atlas 2018).
6.1.4.5 Plants
Habitat for Vancouver Island beggarticks is shorelines of lakes, ponds, creeks, bogs, tidal estuaries, and ditches with fluctuating water levels, usually with standing water in winter and substantial draw down in summer (EC 2015). It is a shade-intolerant species that is out-competed by invasive and densely growing plant species (EC 2015). Given the dense shrub cover and presence of invasive plant species, the potential for this species to occur in the park is low.
An at-risk plant survey was not undertaken as the time of year was not conducive to detection. However, given the highly-disturbed nature of the study area, at-risk plants are not anticipated to occur within the study area; therefore, no negative interactions are anticipated.

7.0 CONSTRUCTION ENVIRONMENTAL MANAGEMENT
This section provides a list of the relevant BMPs and mitigation measures proposed for implementation during construction activities to minimize effects on the natural environment. Mitigation measures are created and customized for each Project to reduce or eliminate harmful effects from a specific project, activity, location and timing. They may be a refinement of a known BMP or represent a completely unique measure designed specifically for a project/activity.
7.1 BEST MANAGEMENT PRACTICES AND GUIDELINES
Provincial BMPs and guiding documents are available, and were reviewed, to ensure that a project is planned and carried out in compliance with applicable legislation, regulations, and policies. Guiding documents and BMPs that should be followed during the Project include, but are not limited to, the following:
• A General Guide to Construction Over or Near Watercourses (CoS 2011);
• Measures to Avoid Causing Harm to Fish and Fish Habitat (DFO 2016);
• A User’s Guide to Working in and Around Water (MOE 2005);
• British Columbia Approved Water Quality Guidelines: Aquatic Life, Wildlife & Agriculture (MOE 2017);
• Develop with Care 2014: Environmental Guidelines for Urban and Rural Land Development in British Columbia (MOE 2014);
• Guidelines for Amphibian and Reptile Conservation during Urban and Rural Development in British Columbia (MFLNRO 2014);
• Best Management Practices for Amphibian and Reptile Salvages in British Columbia (Wind et al. 2013);
• Guidelines for Raptor Conservation during Urban and Rural Land Development in British Columbia (MoE 2013); and
• Best Management Practices for Bats in British Columbia (MoE 2016).
Table 9 provides a summary of key site-specific measures that may be applied to the Project to avoid or minimize potential Project effects described in Section 7.1, including mitigative approaches and strategies derived from the above list of BMPs and guiding documents.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 50 - January 2018
Table 9 Construction Environmental Management Measures
Activity Best Management Practices and Mitigation Measures • Equipment must arrive onsite washed and free of leaks, invasive species, and noxious weeds. • All fuelling, washing, and maintenance of equipment must be conducted at a safe distance at (i.e., at least 30 m away) from aquatic habitats to prevent the introduction of deleterious substances into these habitats (i.e., outside the riparian buffer area). • Use biodegradable fluids in heavy machinery associated with instream works, where practicable, and ensure equipment is clean and free of excess oil and grease prior to initiating work. Protection of • Ensure basic spill kits are available within every vehicle and piece of equipment operating Surface within the Project site. Drainages and Water Quality • Vegetation removal within the riparian buffer area should be minimized to the extent possible. • Clearing, grubbing, drainage and grading work near Class A or B watercourses should occur during dry summer conditions. • The riparian vegetation on Class A or B drainages should be replanted (e.g., with willow stakes) to maintain bank stability, provide shade to the channel, and contribute food and nutrients. • Ensure gravels, rock, riprap, or other materials placed on the banks or within watercourse channels are inert, and free of silt, debris, or other substances deleterious to aquatic life. • Appropriate erosion and sediment control measures (e.g., silt fences, scattered straw, drainage swales) must be implemented prior to the commencement of construction activities, as necessary. • All installed erosion and sediment control measures should be regularly inspected and replaced/modified as required during construction. • Silt fence (or other acceptable product) should be installed along the top of bank of any Erosion and wetted Class A or B watercourses prior to construction activities in that area to prevent Sediment surface runoff from entering the channel. Control • Any soils exposed as a result of Project activities should be covered, and/or other erosion protection measures should be implemented until such time that re-vegetation (soil stabilization) can be implemented. • All sediment-laden water should be directed to stable, vegetated areas away from any watercourses to allow for infiltration back into the ground. • Additional guidance is provided in Appendix D – Erosion and Sediment Control Guidelines. • Conduct instream works on Class A and B watercourses in the dry or within window of least risk (August 1st to September 15th) unless otherwise determined acceptable by a Qualified Environmental Professional (QEP) and/or allowed by the DFO and/or the Ministry of Forests, Lands, and Natural Resource Operations (FLNRO).

Activity Best Management Practices and Mitigation Measures • Minimize the area of vegetation clearing to the extent possible. • Clearly mark the limits of construction activities and appropriate buffers around any sensitive environmental features prior to vegetation clearing. • If possible, trees requiring removal and areas of native shrubs disturbed by clearing activities should be replaced/replanted with the same or similar species. Vegetation • To the extent practicable, maintain hydrology in any new roadside and adjacent ditches to encourage growth of emergent vegetation such as cattail. • Prevent introduction of invasive plants into the work area through use of clean fill materials and inspection of vehicles and machinery for plant parts. • Additional enhancement and/or restoration may be undertaken on the acquired lot at 14082 106 Avenue (Section 8.1). • Maintain habitat connectivity to the extent possible and hub by minimizing vegetation clearing within the GIN corridor and hub. • Conduct raptor nest surveys in advance of clearing activity to identify any active or inactive raptor nests within a 200 m buffer of the clearing boundaries. • Vegetation clearing should ideally be conducted outside of the breeding bird period (March 15 to August 15). Any clearing that occurs within the breeding bird period will require a nest clearing survey due to the potential for tree, shrub, and grassland nesting birds. • Conduct in-stream work, including infilling of ditches in summer months and time of low water levels to reduce potential impacts to breeding amphibians, egg masses, tadpoles and toadlets. If construction is to occur within or near areas of potential native amphibian breeding habitat when wetted, conduct an amphibian salvage as per the requirements of the Wildlife Act and relevant BMPs. Wildlife and Wildlife Habitat • Remove wildlife attractants from the site (i.e. garbage) regularly during construction. • Consider including wildlife crossing structure(s) (i.e., small- to medium-sized mammal underpass(es) within the GIN corridor as part of the final Project design. Any crossing structures should be designed to meet the needs of the widest range of species possible, and designed to minimize the intensity of noise and light coming from the road and traffic. Use topography and natural features as much as possible to encourage the use of any crossing structure(s). Additional measures such as fencing, rock walls, drift fences or other barriers along 105A Avenue, particularly within Hawthorne Park, may also be implemented to encourage use of the crossing(s). • Upon completion of the Project, warning signage for wildlife should be erected along 105A Avenue where it crosses the BC Hydro ROW GIN Corridor and at both ends of vegetated area associated with the GIN Hub (Hawthorne Park). Species at Risk • See “Fish and Fish Habitat”, “Vegetation” and Wildlife and Wildlife Habitat” sections above. • Conduct environmental monitoring, with an emphasis on those works with the greatest potential to impact aquatic and terrestrial habitat. The Environmental Monitor must have Environmental written authority to halt work if environmental monitoring indicates there is a current or Monitoring imminent impact to the environment that has not been otherwise permitted or approved. • Monitor turbidity and pH on an ongoing basis, to ensure that water quality in watercourses meets provincial and City of Surrey’s water quality objectives.

8.0 PROPOSED RESTORATION AND ENHANCEMENT
The proposed Project will impact instream (113 m2) and riparian (1,620 m2) habitat on Hawthorne and Bon Accord creeks. The restoration and enhancement measures described below are proposed to address these anticipated Project effects.
8.1 TERRESTRIAL HABITAT
The City of Surrey will acquire four properties to increase the total area of Hawthorne Park: 14082 106 Avenue, and 14336, 14326, and 14306/14308 108 Avenue. This will result in the addition of 5,946 m2 of existing forested area to the park, and 7,951 m2 of area that can be used for habitat restoration and enhancement (Figure 8).
The GIN corridor #98 within the BC Hydro ROW has also been identified by the City of Surrey Biodiversity Conservation Strategy as having potential for wildlife habitat restoration and enhancement (Diamond Head 2014). Recommendations include:
• Establish hedgerows and shrubs;
• Work with landowners to naturalize adjacent parcels of land;
• Create wetlands;
• Remove barriers to movement; and
• Install signage at road crossings.

8.2 OFF-CHANNEL HABITAT FEATURE
The City of Surrey proposes to create a new off-channel habitat feature within Hawthorne Park that will discharge to Bon Accord Creek (Appendix E). The feature will receive flows from a new ditch constructed on the north side of a new road alignment (the 105A Avenue extension) conveying stormwater from the local area network and from bioswales conveying drainage from the Hawthorne Park parking lot and nearby water park facility. There are two distinct components to the design that will be constructed in series. The first is a sediment basin and wetland feature that is intended to improve stormwater quality prior to discharge to fish habitat. The second is an off-channel pond that will provide habitat for amphibians, birds, including waterfowl, and small mammals.
Drainage from the new roadside ditch and parking lot will enter a sediment basin (approximately 141 m2). The sediment basin is designed to trap and contain sediment consisting of fine sands that are mobilized in runoff water. The basin will be approximately 1 m to 2 m deep. It will be separated from the biofiltration wetland by an earthen berm that will allow water to decant evenly into the wetland.
The engineered biofiltration wetland (approximately 3,470 m2), will be approximately 0.5 m deep and will be densely planted with vegetation suitable for water filtration and fine sediment capture, such as common cattail (Typha latifolia), sedges (Carex sp.), and rushes (Juncus sp.). The primary purpose of the wetland habitat is to remove potentially harmful chemical substances (e.g., heavy metals and hydrocarbons) that may be entrained in runoff water entering the facility prior to discharge to fish habitat. A small area of open water (approximately 150 m2) will be incorporated into the wetland design.
A constructed weir will separate the wetland from Bon Accord Creek and will create a barrier to fish passage, as the wetland is considered a stormwater quality improvement facility and was not designed to sustain fish year-round.
A bioswale will direct water from the splash park to the downstream end of the wetland. This water is anticipated to be chlorinated at its source. The bioswale will be lined with gravel and planted with filtering vegetation such as sedges. The intent of the swale is to allow sediment to settle and encourage dechlorination of the water prior to entering a small pond (approximately 110 m2) immediately downstream of the wetland.
An existing 450 mm culvert (at the trail crossing) will be removed and replaced with a clear span bridge. This culvert removal will require instream work and will result in approximately 37 m2 of daylighted Class A channel habitat. Approximately 9,500 m2 of new riparian habitat will be created as a result of proximity to the new off-channel habitat feature.
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 55 - January 2018
An additional sediment basin and bioswale (approximately 400 m2) will also be constructed on the west bank of Bon Accord Creek. This sediment basin will capture run-off from the road surface, and is designed to trap and contain sediment consisting of fine sands that are mobilized in runoff water. The basin will be approximately 1 m to 2 m deep and will not be fish accessible. The bioswale will be planted with vegetation suitable for sediment and metals capture prior to discharge into Bon Accord Creek.
8.3 HAWTHORNE CREEK RIPARIAN AREA
A parcel of property has been acquired at 14082-106 Avenue, on the northwest corner of Hawthorne Park, at the corner of 106 Avenue and the 140B Street road allowance. This property is located approximately 18 m east of Hawthorne Creek, and may be used to mitigate riparian area that is negatively impacted along the creek. In addition, the 104B Street road allowance will be closed, adding 2,512 m2 of riparian area on Hawthorne Creek to the park (Figure 8). Invasive species removal may be considered on this property to improve riparian vegetation and upland habitat. This parcel is expected to eventually be incorporated into Hawthorne Park. Instream enhancements on Hawthorne Creek may also be considered to improve fish access and habitat within the Class B section. Approximately 160 m2 of instream habitat is available for enhancement in the Class B section of Hawthorne Creek.
8.4 BON ACCORD CREEK CULVERT CROSSING
The erosion protection design at the inlet and outlet of the proposed Bon Accord Creek culvert will include placement of riprap material. To help avoid loss of surface flow during low water periods and to create a functional fish habitat feature, a deep pool habitat (approximately 5 m wide x 10 m long x 1.0 m) has been incorporated in the design at the culvert outfall. This will require over-excavation of the zone where the riprap material will be placed to enable sufficient erosion protection as well as creation of this pool habitat feature.
8.5 BON ACCORD CREEK CULVERT REMOVAL AND DAYLIGHTING
An existing 450 mm diameter, 10 m long culvert will be removed from Bon Accord Creek. The culvert is located on an existing trail located just north of the study area which will be realigned following road construction. A wooden pedestrian bridge will be installed in its place. The removal of the culvert will result in the addition of approximately 37 m2 of Class A instream habitat and 200 m2 of riparian habitat.

9.0 RESIDUAL EFFECTS ASSESSMENT
This section of the assessment considers potential residual effects on fish and fish habitat, vegetation, wildlife and wildlife habitat, and species at risk following the implementation of the proposed mitigation and restoration/enhancement measures. Residual effects were evaluated based on the criteria described in
Table 10 below.

Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 57 - January 2018
The anticipated residual impacts associated with the proposed Project are summarized below in Table 11. Overall, the risk of significant negative residual impacts on the environmental components (fish habitat, wildlife habitat and species at risk) was assessed as low, provided the recommended mitigation, restoration, and enhancement measures listed in Section 8 are effectively implemented during construction and (where applicable) maintained during operation.
Table 11 Residual Effects Evaluation
Potential Component Residual Effects (following implementation of mitigations) Effects Residual effects on water quality associated with construction activities are expected to be short-term, low in magnitude and localized in geographic scale, provided appropriate mitigation measures are implemented. Long-term effects to Change in water quality during the operational phase of the Project (because of stormwater surface water runoff) are expected to be of a negligible or low magnitude, when compared to quality the existing condition, such that no significant residual impacts are expected. Following construction of the off-channel habitat feature, water quality in Bon Accord Creek may improve. Overall, there will be a long-term loss of 89 m2 of riparian habitat including ~65 m2 of instream Class A fish habitat on Bon Accord Creek and ~24 m2 of Class B habitat on Hawthorne Creek related to placement of culverts for the road. These losses and temporary (short-term) disturbances are primarily associated with low value (e.g., low productivity) fish habitats. A culvert will be removed from Bon Accord Creek, resulting in daylighting of approximately 37 m2 of instream habitat. A net loss of 23 m2 of instream fish habitat is anticipated. However, Fish and negative residual impacts to fish habitat productivity are unlikely, provided the Fish culverts at Bon Accord Creek and Hawthorne Creek are designed and Habitat Alteration of constructed in a manner that maintains fish access and the proposed fish habitat instream and restoration and enhancement measures/features are implemented. riparian habitat Any changes to water temperatures, nutrient and food supply because of riparian vegetation clearing are expected to be reversible, of short- to moderate- term duration, and of low magnitude, particularly following implementation of the proposed riparian restoration activities. Significant residual impacts in fish- bearing watercourses within or downstream of the study area are unlikely. The proposed habitat feature is expected to contribute a significant source of food and nutrients to Bon Accord Creek. Approximately 1,140 m2 of riparian habitat will also be removed for the road; however, this will be mitigated by creation of approximately 9,500 m2 of riparian habitat as a result of the new habitat feature. Incidental Fish population numbers are expected to be low to nil in Hawthorne and Bon injury or Accord creeks within the study area. No residual effects to fish are expected if mortality of appropriate mitigation measures are implemented (e.g., work in Class A and B fish watercourses during the least risk window).
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 58 - January 2018
Potential Component Residual Effects (following implementation of mitigations) Effects Plant communities in the construction footprint and residential areas consist largely of mowed grass and weedy species, which are prevalent within the study area and surrounding habitat. Adverse residual effects in these areas are Loss or unlikely. alteration of Exceptions are the ecosystems within Hawthorne Park. Trees or native shrubs vegetation to be cleared in the park should be replaced/replanted with the same or similar Vegetation species to mitigate negative effects to vegetative habitat value in these areas. No negative residual effects are anticipated if mitigation measures are implemented and restoration activities are undertaken. Introduction/ Residual effects are unlikely if appropriate mitigation measures are spread of implemented. invasive plants Sensory disturbance to wildlife may result from during construction as well as during the Project’s operational phase. However, given the presence of existing Sensory infrastructure near the Project it is anticipated that wildlife in the area are already disturbance accustomed (habituated) road) to a similar baseline level of disturbance. As a result, negative residual impacts are unlikely if appropriate mitigation measures are implemented. The Project footprint represents permanent loss of habitat for wildlife, and areas of vegetation disturbance or clearing of vegetation followed with riparian planting represent a temporary alteration of wildlife habitat. However, this alteration/loss Wildlife and Habitat of habitat is on a small scale, and similar- or better-quality habitat is prevalent Wildlife alteration/ loss nearby. Residual negative impacts on wildlife are unlikely. The new off-channel Habitat habitat feature is expected to provide a variety of new habitats for wildlife that will increase the ecological diversity in the park. Residual effects are unlikely during the construction phase provided appropriate mitigation measures in place. Increased signage and/or wildlife crossing structures are expected to mitigate injury or mortality of wildlife during the Injury or operational phase such that negative residual impacts on wildlife populations are mortality not expected to be significant. The culvert at Bon Accord Creek crossing of the new 105A Avenue alignment is expected to also provide a crossing location for small mammals and amphibians. For the species at risk considered to have moderate- to high- potential to occur on site, sensory disturbance is generally expected to be limited to temporary disturbance of foraging behavior during the construction phase. As described for Sensory wildlife and wildlife habitat above, species at risk present within the study area disturbance are likely already habituated to a similar background level of disturbance; therefore, significant negative residual impacts are unlikely if appropriate mitigation measures are implemented. Species at As described above for wildlife and wildlife habitat, any alteration or loss of Risk Habitat habitat is on a small scale, and similar- or better-quality habitat is available alteration/ loss nearby. Residual negative impacts on the identified species at risk due to habitat alteration / loss are unlikely. Implementation of appropriate mitigation measures (i.e., construction timing, Injury or nest surveys, and amphibian salvages) are expected to avoid or minimize any mortality potential effects such that significant adverse impacts at the population level for any of the identified species at risk are unlikely.

9.1 QEP DETERMINATION REGARDING POTENTIAL FOR RESIDUAL SERIOUS HARM TO FISH
Based on the features, function, and conditions observed at the time of the field assessments, the Class A and B drainages in the study area generally represented low value fish habitat, with some moderate value meso-habitats present. Although both Hawthorne and Bon Accord creeks are classified as Class A (fish- bearing) watercourses, no confirmed records of fish presence in the assessed reaches were available. The Pathway of Effects assessment conducted by a Hemmera Qualified Environmental Professional identified a low potential for adverse residual effects to fish and fish habitat following effective implementation of relevant mitigation measures. Overall, with construction of the proposed off-channel habitat feature, post- mitigation productivity of the drainages within the study area is expected to improve (Section 8.2).
Construction of the Project will result in an impact to -89 m2 of low quality, Class A instream habitat on Bon Accord Creek, and an estimated -24 m2 of Class B habitat on the Tributary to Hawthorne Creek, as a result of construction of the road crossing culverts. Culvert removal on Bon Accord Creek will daylight a short section of channel resulting in a gain of approximately +53 m2 of Class A habitat. This will help balance the permanent impact to -36 m2 of Class A instream habitat on Bon Accord Creek. In addition, an approximately +390 m2 of new Class B ditch will also be added to the north side of the new road alignment and will contribute to the hydrology of the habitat feature and result in a net gain of +366 m2 of Class B habitat for the Project. Overall, a net increase of +342 m2 is expected.
To counterbalance the -1,620 m2 of riparian habitat losses due to road construction, the Project is anticipated to gain approximately +200 m2 of riparian habitat as a result of channel daylighting on Bon Accord Creek. In addition, the habitat feature will result in the creation of approximately +9,500 m2 of riparian habitat following construction of the proposed habitat feature, for a total of +9,700 m2 of new riparian habitat. The net balance of riparian habitat for the Project is approximately +8,080 m2.
The overall habitat balance associated with the Project is provided in Table 12.
Based on our understanding of the proposed Project, the information available regarding the local natural environment, the features, functions, and conditions of the fish habitat observed in the field and the favorable fish habitat balance, this Environmental Impact Assessment concludes there is a low risk of the proposed Project causing serious harm to CRA fish, provided the Project is constructed utilizing the proposed BMPs and mitigation measures listed in Section 7.0 and the proposed restoration and enhancement measures outlined in Section 8.0.

9.2 WILDLIFE
The Project will result in fragmentation of Hawthorne Park from a wildlife habitat perspective; however, the wildlife habitat values associated with the park were low to moderate and primarily associated with common urban wildlife species.
Although construction of the new road will permanently remove habitat in the Project footprint, better quality habitat exists to the north through the remainder of Hawthorne Park and into Invergarry Park. The GIN corridor in the BC Hydro ROW will still act as a travel corridor for wildlife as only the southern section will be altered. In general, no permanent impacts to wildlife are anticipated.
9.3 SPECIES AT RISK
In general, habitat for most species at risk is considered to be of low quality, or not available, within the study area proposed for development. Due to its location between several busy city streets (104 Avenue and 108 Avenue), Hawthorne Park is relatively isolated from other greenspaces (i.e., Invergarry Park and the Bon Accord Creek corridor to the north).
No water features with evident emergent or submerged vegetation, as deemed suitable for northern red- legged frog or western toad breeding, were noted in the study area. The Bon Accord Creek Ponds in the north end of the park were deemed to have slightly higher potential for breeding use by these two species of amphibian.
The study area was deemed unlikely to support Oregon forestsnail. Habitats are likely not moist enough in the summer based on consideration of vegetation present during site visits, and in consideration of the absence of big-leaf maple as a key indicator of presence. As such, the habitat rating for Oregon forestsnail is low.
No great blue heron nests were observed in the study area. While this species is known to be present occasionally in the park, breeding use by great blue heron appears unlikely at present.
Habitat for Pacific water shrew was deemed to be low-moderate quality throughout the study area. One or two habitat requisites for Pacific water shrew in each assessed location were rated as suitable – water depth and width, or coarse woody debris presence, or riparian cover. However, none of the assessed sites had all of these habitat requisites in the optimal moderate to high portion of the rating scheme. Access along watercourses is generally poor across the park. In addition, barriers associated with 104 and 108 avenues are considered insurmountable by Pacific water shrew based on current knowledge of their dispersal capabilities. If Pacific water shrew are present, their life requisites would have to be supplied by habitat in the park, as migration potential is limited. The isolation of the park from other adjacent habitats means it is unlikely that in-migration of terrestrial species could supplement a population in the sub-optimal
Aplin & Martin Consultants Ltd. Hemmera 105A Avenue Improvements – Draft EIA - 62 - January 2018 habitat of the park, or that individuals living in the park could move out to meet their habitat requisites at other locations. In addition to the isolation provided by 104 and 108 avenues, to the east 144 Street is a barrier, and to the west the urban developments beyond the BC Hydro right-of-way at 140B Street is also a barrier to terrestrial species movement.

PROPOSED WORKS
Detailed Description of Works: Please note: this is a re-submission of work approved under application number 100205132. Work did not proceed this year and has been moved to 2018. None of the details have changed.
A new concrete box culvert (see attached drawings) will be installed on Bon Accord Creek to allow access and base for the 105A Ave. road extension and rep-construction preload. BMPs for culvert installation and in-stream works will be followed, and erosion and sediment control measure employed to protect water quality and fish Tracking Number: 100230522 | Version 1.0 | Submitted Date: Nov 17, 2017 Page 2 of 6 habitat on Bon Accord Creek during construction. The culvert will be installed during the fish window. To help avoid loss of surface flow during low water periods and to create functional fish habitat features, deep pool habitats (approximately 5 m wide x 10 m long x 1.0 m) are proposed to be incorporated in the design. This will require over-excavation of the zone where the riprap material will be placed to enable sufficient erosion protection as well as creation of this pool habitat features.

Re: Notice to Habitat Officer / Changes in and about a Stream under Part 3 Water Sustainability Regulation
Your Notification to a Habitat Officer under the Water Regulation (Part 3 of the regulation) regarding your proposal to make changes in and about a stream of the kind described in section 39 of the regulation, has been received.
Please Note: Only changes in and about a stream of the kind listed in the Water Sustainability Regulation (Part 3 "Changes in and About a Stream") can proceed on notification and in accordance with requirements of the regulation including any terms and conditions specified by a Habitat Officer. An approval under the Water Sustainability Act for the change is otherwise required if the change proposed is not of the kind listed in section 39 of the regulation.
Under the provisions of the regulation, the Habitat Officer has 45 days following receipt by the Ministry of this notification to request additional information from you and to specify additional terms and conditions specific to your proposal, if warranted. A person making a change in and about a stream under this regulation, other than under section 39(1)(o) to (s) or 39(2) or 39(5), must then make that change in accordance with the regulation and any terms and conditions specified by the Habitat Officer (including those further described in #1-17 below or as specified subsequently within 45 days of Habitat Officer receipt of this notice).
Therefore, if you have not heard back from the Habitat Officer within 45 days of our receipt of your notice providing you with a statement of any additional terms and conditions specified by the Habitat Officer with respect to your proposal, you may proceed with the proposed changes in and about a stream but must satisfy the requirements of Part 3 of the regulation and also comply with the following terms and conditions in making those changes:
1. Any work associated with the proposed changes in and about a stream must not cause stream channel instability or increase the risk of sedimentation into the stream.
2. During work onsite, erosion and sediment control materials must be available onsite at all times and must be installed if sedimentation is likely to occur into the stream. A contingency plan must be developed outlining the measures to be taken by workers when carrying out any work to control erosion and sediment.
3. Soil disturbance must not occur in heavy rain conditions and any soil removed must be placed in a location that ensures that sediment or debris does not enter the stream.
4. Within a work area, water that contains sediment must be pumped to a vegetated area away from the stream where it can seep into the ground, or to a settling pond that is sufficiently far from the stream to allow sediment to settle out before the water returns to the stream.
5. The disturbance of stream bank vegetation must not occur or be minimized as much as possible. Page 1 of 5 6. Any areas that are disturbed during the work (such as exposed soil) must be promptly restored at a minimum to the pre-disturbance condition. Note: Guidance is provided in the Enhancement Section of the Best Management Practices Instream Works
7. If possible, work must be conducted on, and equipment located and operated from, dry land (no water present) and the worksite must be isolated from flowing water.
8. Any equipment used in conducting work must be in good mechanical condition and, when operating in close proximity to the wetted perimeter of a stream, the operator must prevent entry of any substance, sediment, debris or material (e.g., hydrocarbons, silt) into the stream so as to prevent harm to fish, wildlife or the aquatic ecosystem of a stream. Note that Section 46 of the Water Sustainability Act prohibits the introduction of foreign matter into a stream. Failure to comply may result in a remediation order and it is also an offence to do so.
9. The original rate of water flow in the stream (existing prior to commencing work) must be maintained upstream and downstream of the worksite during all phases of instream activity associated with the work.
10. When work requires de-watering or isolation of the worksite in the stream, a permit for the salvage of fish and wildlife must be obtained prior to commencing work. All required salvage permits must be obtained from FrontCounter BC : http://www.frontcounterbc.gov.bc.ca/. Any salvage must be carried out by a qualified environmental professional (such as an R.P.Bio.).
11. Following de-watering or isolation of the worksite, stream flow must be returned gradually to the de-watered or isolated area within the stream and not in a single sudden rush so as to avoid erosion of the stream channel and sediment delivery to the stream.
12. The stream channel width must not change as a result of the work.
13. Any materials, such as riprap or gabion rock, placed within the stream must be clean and not contain substances that could be harmful to fish, wildlife or the aquatic ecosystem of the stream.
14. Any areas disturbed as part of the work must be restored as close as possible to their pre-disturbance condition. Any soil exposed at the worksite must be promptly re-vegetated.
15. Subject to section 16 and 17 below, the work must be completed during the timing window for the stream in respect of which the changes are proposed. The applicable timing window (by region and/or by stream) are specified in the following links (see below) and are designed to protect fish, wildlife or the aquatic ecosystem of a stream. To determine the timing window, please select the relevant region from the map: http://www.frontcounterbc.ca/pdf/RegionMap.pdf and then determine the applicable timing window:*Regional Timing Windows: http://www2.gov.bc.ca/gov/content/environment/air-land-water/water/water-licensing-rights/working-around-water/regional-terms-c onditions-timing-windows< 16. In addition to the timing windows specified in section 15 above, work may be carried out during the following times provided these requirements are met when the changes are carried out: Page 2 of 5 i. If the stream channel is naturally dry (no flow) or frozen to the bottom at the worksite and the instream work / activity associated with the proposed change will not adversely impact fish, wildlife or the aquatic ecosystem of the stream (e.g. not result in any substance, sediment, debris or other material entering or leaching into the stream that would adversely affect fish, wildlife or the aquatic ecosystem), ii. In the construction of a winter crossing, the stream channel is frozen to the bottom at the worksite and related work does not adversely impact the stream channel (including stream bed and banks), or fish, wildlife or the aquatic ecosystem of the stream, or impede their passage (in both directions) in the stream. 17. If your work is proposed outside of the timing window (as described in section 15 above), you must retain a qualified environmental professional (such as an R.P. Bio.). The professional will be responsible for providing a written technical rational that assesses and addresses the risks of the proposed changes in and about a stream, including proposing site specific mitigation (e.g. an Erosion Control Plan that identifies contingency measures and emergency procedures related to the proposal) and onsite monitoring of their implementation. This document must be submitted to the Habitat Officer via Front Counter B.C. with reference to your file number (shown on top of this document). In proceeding outside the timing window in accordance with recommendations by your qualified environmental professional, you must comply with any measures specified by that professional to prevent impacts on the stream channel (including stream bed and banks) or fish, wildlife or the aquatic ecosystem of the stream, as well as any Habitat Officer terms and conditions specified in the confirmation of receipt of your original Notice. In summary, you must meet the terms and conditions described above, as well as any additional terms and conditions specified by the Habitat Officer in respect of your proposal within 45 days of the Ministry's receipt of your notice, if any were specified. In addition, you must also meet any other requirements of the regulation, as are described in Part 3 of the Water Sustainability Regulation found at http://www.bclaws.ca/ Also, for assistance to the public, the Province has developed clear guidance/practices, also referred to as best management practices, for working around water and for designing and implementing different types of changes in and about a stream, particularly in respect of instream works. This information in combination with the terms and conditions described above, including any additional Habitat Officer terms and conditions specified, if all followed, will help ensure that your changes in and about a stream will be compliant with the regulation and related legislation, as well as minimizing impacts on the environment (including related fish, wildlife and the aquatic ecosystem) in the stream and stream channel. Follow the links and website directions (see below) to review the provincial guidance/practices provided for your proposed works.

SITE Location ID: Hawthorne Creek STREAM Name of the Stream: Hawthorne Creek Source Flows Into: Bon Accord Creek PROPOSED WORKS Detailed Description of Works: This Notification covers the connection of four catch basins to Hawthorne Creek and the installation of a new culvert on a tributary to Hawthorne Creek. New Catch Basin Connection: The proposed 105A Avenue extension will require installation of four (two groups of two) new catch basins along the roadway. These catch basins will tie into Hawthorne Creek. The first is located immediately east of the new 105A Avenue intersection with 140th Street and the tie in will occur to the existing storm main that discharges into the culvert that conveys Hawthorne Creek (which extends east of the intersection). The second tie-in location is immediately west of the 105A Avenue intersection with 140B Street. The location of these catch basins is provided on the attached engineering drawings. Maintenance (i.e., dredging) of the Hawthorne Creek channel between the Tracking Number: 100221997 | Version 1.0 | Submitted Date: Oct 12, 2017 Page 2 of 7 outfall east of 140 Street and 140B Street may be necessary to improve flow conveyance in this section of the Hawthorne Creek channel. Hawthorne Creek is a red-coded stream (fish bearding at some point during the year). The dredging would be restricted to the channel bed to maintain hydrology and would occur in the instream least risk work window. The depth of dredging would be confirmed during later stages of project design; however, depth will be minimized to the extent possible to avoid damage to fish habitat.

This tributary is a yellow-coded stream (non-fish-bearing, but provides a significant source of food and nutrients to fish and fish habitat downstream). The culvert will be designed similarly to the Bon Accord culvert previously approved (tracking number 100205132) for installation along 105A Avenue as part of the same project. The box culvert will be 29.02 m long by 1829mm x 914mm. Culvert installation activity would occur in the instream least risk work window. The approved Bon Accord culvert design drawing is attached to this application for reference. Riparian vegetation within the proposed work area is generally comprised of grasses. Approximately 1140 sq. m. of riparian area and 257 sq. m. of instream habitat will be impacted.

Re: Notice to Habitat Officer / Changes in and about a Stream under Part 3 Water Sustainability Regulation Your Notification to a Habitat Officer under the Water Regulation (Part 3 of the regulation) regarding your proposal to make changes in and about a stream of the kind described in section 39 of the regulation, has been received. Please Note: Only changes in and about a stream of the kind listed in the Water Sustainability Regulation (Part 3 "Changes in and About a Stream") can proceed on notification and in accordance with requirements of the regulation including any terms and conditions specified by a Habitat Officer. An approval under the Water Sustainability Act for the change is otherwise required if the change proposed is not of the kind listed in section 39 of the regulation. Under the provisions of the regulation, the Habitat Officer has 45 days following receipt by the Ministry of this notification to request additional information from you and to specify additional terms and conditions specific to your proposal, if warranted. A person making a change in and about a stream under this regulation, other than under section 39(1)(o) to (s) or 39(2) or 39(5), must then make that change in accordance with the regulation and any terms and conditions specified by the Habitat Officer (including those further described in #1-17 below or as specified subsequently within 45 days of Habitat Officer receipt of this notice). Therefore, if you have not heard back from the Habitat Officer within 45 days of our receipt of your notice providing you with a statement of any additional terms and conditions specified by the Habitat Officer with respect to your proposal, you may proceed with the proposed changes in and about a stream but must satisfy the requirements of Part 3 of the regulation and also comply with the following terms and conditions in making those changes: 1. Any work associated with the proposed changes in and about a stream must not cause stream channel instability or increase the risk of sedimentation into the stream. 2. During work onsite, erosion and sediment control materials must be available onsite at all times and must be installed if sedimentation is likely to occur into the stream. A contingency plan must be developed outlining the measures to be taken by workers when carrying out any work to control erosion and sediment. 3. Soil disturbance must not occur in heavy rain conditions and any soil removed must be placed in a location that ensures that sediment or debris does not enter the stream. 4. Within a work area, water that contains sediment must be pumped to a vegetated area away from the stream where it can seep into the ground, or to a settling pond that is sufficiently far from the stream to allow sediment to settle out before the water returns to the stream. 5. The disturbance of stream bank vegetation must not occur or be minimized as much as possible. Page 1 of 5 6. Any areas that are disturbed during the work (such as exposed soil) must be promptly restored at a minimum to the pre-disturbance condition. Note: Guidance is provided in the Enhancement Section of the Best Management Practices Instream Works 7. If possible, work must be conducted on, and equipment located and operated from, dry land (no water present) and the worksite must be isolated from flowing water. 8. Any equipment used in conducting work must be in good mechanical condition and, when operating in close proximity to the wetted perimeter of a stream, the operator must prevent entry of any substance, sediment, debris or material (e.g., hydrocarbons, silt) into the stream so as to prevent harm to fish, wildlife or the aquatic ecosystem of a stream. Note that Section 46 of the Water Sustainability Act prohibits the introduction of foreign matter into a stream. Failure to comply may result in a remediation order and it is also an offence to do so. 9. The original rate of water flow in the stream (existing prior to commencing work) must be maintained upstream and downstream of the worksite during all phases of instream activity associated with the work. 10. When work requires de-watering or isolation of the worksite in the stream, a permit for the salvage of fish and wildlife must be obtained prior to commencing work. All required salvage permits must be obtained from FrontCounter BC : http://www.frontcounterbc.gov.bc.ca/. Any salvage must be carried out by a qualified environmental professional (such as an R.P.Bio.). 11. Following de-watering or isolation of the worksite, stream flow must be returned gradually to the de-watered or isolated area within the stream and not in a single sudden rush so as to avoid erosion of the stream channel and sediment delivery to the stream. 12. The stream channel width must not change as a result of the work. 13. Any materials, such as riprap or gabion rock, placed within the stream must be clean and not contain substances that could be harmful to fish, wildlife or the aquatic ecosystem of the stream. 14. Any areas disturbed as part of the work must be restored as close as possible to their pre-disturbance condition. Any soil exposed at the worksite must be promptly re-vegetated. 15. Subject to section 16 and 17 below, the work must be completed during the timing window for the stream in respect of which the changes are proposed. The applicable timing window (by region and/or by stream) are specified in the following links (see below) and are designed to protect fish, wildlife or the aquatic ecosystem of a stream. To determine the timing window, please select the relevant region from the map: http://www.frontcounterbc.ca/pdf/RegionMap.pdf and then determine the applicable timing window:*Regional Timing Windows: http://www2.gov.bc.ca/gov/content/environment/air-land-water/water/water-licensing-rights/working-around-water/regional-terms-c onditions-timing-windows< 16. In addition to the timing windows specified in section 15 above, work may be carried out during the following times provided these requirements are met when the changes are carried out: Page 2 of 5 i. If the stream channel is naturally dry (no flow) or frozen to the bottom at the worksite and the instream work / activity associated with the proposed change will not adversely impact fish, wildlife or the aquatic ecosystem of the stream (e.g. not result in any substance, sediment, debris or other material entering or leaching into the stream that would adversely affect fish, wildlife or the aquatic ecosystem), ii. In the construction of a winter crossing, the stream channel is frozen to the bottom at the worksite and related work does not adversely impact the stream channel (including stream bed and banks), or fish, wildlife or the aquatic ecosystem of the stream, or impede their passage (in both directions) in the stream. 17. If your work is proposed outside of the timing window (as described in section 15 above), you must retain a qualified environmental professional (such as an R.P. Bio.). The professional will be responsible for providing a written technical rational that assesses and addresses the risks of the proposed changes in and about a stream, including proposing site specific mitigation (e.g. an Erosion Control Plan that identifies contingency measures and emergency procedures related to the proposal) and onsite monitoring of their implementation. This document must be submitted to the Habitat Officer via Front Counter B.C. with reference to your file number (shown on top of this document). In proceeding outside the timing window in accordance with recommendations by your qualified environmental professional, you must comply with any measures specified by that professional to prevent impacts on the stream channel (including stream bed and banks) or fish, wildlife or the aquatic ecosystem of the stream, as well as any Habitat Officer terms and conditions specified in the confirmation of receipt of your original Notice. In summary, you must meet the terms and conditions described above, as well as any additional terms and conditions specified by the Habitat Officer in respect of your proposal within 45 days of the Ministry's receipt of your notice, if any were specified. In addition, you must also meet any other requirements of the regulation, as are described in Part 3 of the Water Sustainability Regulation found at http://www.bclaws.ca/ Also, for assistance to the public, the Province has developed clear guidance/practices, also referred to as best management practices, for working around water and for designing and implementing different types of changes in and about a stream, particularly in respect of instream works. This information in combination with the terms and conditions described above, including any additional Habitat Officer terms and conditions specified, if all followed, will help ensure that your changes in and about a stream will be compliant with the regulation and related legislation, as well as minimizing impacts on the environment (including related fish, wildlife and the aquatic ecosystem) in the stream and stream channel. Follow the links and website directions (see below) to review the provincial guidance/practices provided for your proposed works.

Hemmera Erosion and Sediment Control Guidelines – 105A Avenue - 1 - December 2017 1.0 INTRODUCTION This Erosion and Sediment Control Plan (ESC Plan or the Plan) was prepared by Hemmera Envirochem Inc. (Hemmera) on behalf of Aplin & Martin Consultants Ltd. (Aplin & Martin) to fulfil the requirements of the City of Surrey ESC Bylaw 16138 and provide as a guideline for contractors to prepare their site-specific ESC plan during construction. In support of an ESC Permit application and creation of task- and site-specific ESC plans to be created by the Contractor, this document addresses the following areas: • Proposed best management practices (BMPs); • Required ESC measures; • Delineation of responsibilities of monitoring personnel; and • Site inspection and performance monitoring. The overall purpose of this ESC Plan is to obtain a City of Surrey ESC Permit and provide sufficient guidance and direction necessary to ensure compliance. The ESC Supervisor for the Project will oversee all construction activities to monitor compliance with the City of Surrey ESC permits and other regulatory permits and approvals. The Contractor will be responsible for appointing an Environmental Monitor. The design objective of this ESC Plan is to help ensure all site discharge water that enters aquatic habitat is less than 60 nephelometric turbidity units (NTUs) and/or 75 mg/l of total suspended solids (TSS) (see Section 2.2.4) and to ensure the site-specific plans developed by the Contractor adhere to these guidelines. Provided below are the specific ESC measures and BMPs that will be applied by the Contractor, where applicable and practicable, during construction activities. Aplin & Martin Consultants Ltd. Hemmera Erosion and Sediment Control Guidelines – 105A Avenue - 2 - December 2017 2.0 EROSION AND SEDIMENT CONTROL GUIDANCE All ESC measures listed below must be installed, inspected, and maintained (as applicable) by the Contractor during construction. Where these measures are ineffective or insufficient, additional measures or facilities must be employed to ensure the Project meets or exceeds all environmental criteria specified in this plan, as well as all applicable permits and approvals, environmental legislation, and relevant municipal bylaws. Any alternative measures proposed will be discussed with the ESC Supervisor and Environmental Monitor, and approved by Aplin & Martin and/or the City of Surrey. Hemmera has prepared a diagram (Figure 1 - Attachment A) that shows the Project location and general locations where: • Catch basins and other stormwater features (that lead to aquatic habitat) are located; • Water may be discharged to vegetation (if required); • Perimeter controls will be established; and • Anticipated access and egress will occur. Erosion and sediment control features should be field-fit, and approved by the Environmental Monitor and ESC Supervisor following installation. 2.1 SOIL CONSIDERATIONS Geotechnical test holes dug within Hawthorne Park generally encountered sandy / gravelly fill over a sequence of soft peat / soft clayey silt underlain by dense silty sand (i.e., compact sand with some gravel fill to the depths of 1.4 to 2.4 meters, peat to the depths of 2.3 to 5.2 meters, and silt to the depths of 4.0 to 8.8 meters) (Braun Geotechnical 2017). Note: When native till / silt materials are exposed to water and are eroded they becomes viscous and are difficult to manage. Once suspended in water, these soil particles may be quite challenging to remove without active flocculation and filtration. 2.2 GENERAL The following conditions and information apply to all stages of road construction and set the general, high level expectations for the Contractor prior to and following commencement of work. • Drainage patterns will be assessed, and if possible, be altered to avoid potential erosion and sedimentation issues; • Erosion control measures will be given priority before sediment control measures; • All discharge water leaving the work space must conform to the City of Surrey water quality discharge criteria at all times; Aplin & Martin Consultants Ltd. Hemmera Erosion and Sediment Control Guidelines – 105A Avenue - 3 - December 2017 • All ESC measures must be installed to the satisfaction of the ESC Supervisor and in accordance with any applicable ESC permits and/or plans; and • All ESC features and measures will be regularly inspected by the Environmental Monitor and /or the ESC Supervisor to ensure that they are functioning properly, and will be maintained by the Contractor when necessary. 2.3 BEST PRACTICES The Contractor will implement the following general BMPs during construction: • Divert clean surface water around the work space prior to clearing (where practical) to avoid ESC measures; • Use existing disturbed areas for equipment and material laydown whenever possible; • Avoid unnecessary vegetation clearing whenever possible to keep soils intact and from being eroded by wind or water; • Use equipment that will minimize surface disturbance, silt compaction, and topsoil loss (e.g., equipment that is tracked or has wide tires); • Restrict grading activity to the greatest extent possible within the work spaces to prevent disturbance to vegetated areas and soil stabilizing root structures; and • Site preparation and construction activities should avoid compaction of exposed soils to the extent practicable. Compaction decreases water infiltration to soils and increases surface water velocities resulting in increased erosion potential. 2.3.1 Perimeter Control During construction, perimeter control must be established along the boundaries of the entire alignment where water can enter and exit the work space. The perimeter control must consist of sediment or silt fence for purposes of exclusion (e.g., along the high side of the work space to prevent water entry). 2.3.2 Site Access and Egress • Restrict access to the peat bog area during construction; • Existing roadways and infrastructure should be used to access work sites and reduce the number of access points to minimize traffic zones and potential for tracking mud, soil, and debris on to roadways; • All access and egress locations must have a vehicle wash station or rumble strip / gravel pad present, as necessary, to remove mud and debris from the tires and undercarriage of vehicles prior to exit onto a municipal roadway; • Measures must be implemented to prevent sediment-laden water from entering any municipal catch basins. Measures may include impermeable covers or proprietary filter bags that are approved by the ESC Supervisor. All measures to protect catch basins will be inspected regularly and cleaned/replaced as needed (removal with machinery may be required), especially after significant rain events; Aplin & Martin Consultants Ltd. Hemmera Erosion and Sediment Control Guidelines – 105A Avenue - 4 - December 2017 • All measures to protect catch basins will be inspected regularly and cleaned/replaced as needed (removal with machinery may be required); • Mud and debris tracked onto a municipal roadway must be immediately swept clean by a mechanical sweeper on an ongoing basis until the issue can be rectified on site to prevent future track out; and • Work pads will be employed to minimize exposure and disturbance of soils, particularly on slopes leading to watercourse crossings and in wet areas. Work pad material options are listed in Table 1. Table 1 Work Pad Categories Material Comments Sand May not be acceptable in agricultural soil. Gravel or 3” minus blast rock May not be acceptable in agricultural soil. Can greatly help bearing strength, eases removal of work pad materials, and Geotextile fabric prevents mixing of topping material and native soil. Permanent placement may not be acceptable. Interlocking work pads (plastic, Interlocking pads (e.g., duradeck or rig-matting) can create a robust and stable steel, concrete, wood) access route that protects soil from erosion and mobilization. 2.3.3 Working in or Near Fish and Fish Habitat Fish habitat, as defined by the Fisheries Act, includes “spawning grounds and any other areas, including nursery, rearing, food supply and migration areas, on which fish depend directly or indirectly in order to carry out their life processes”. This section outlines mitigation measures that should be undertaken in order to preserve fish habitat values associated with Bon Accord and Hawthorne creeks. The measures described below shall be employed during the construction activities of all watercourses that provide fish habitat, including, but not limited to: the removal and restoration of riparian vegetation; water diversions; stream crossings; and the use of machinery near watercourses: 2.3.3.1 Instream Work • Employ all necessary mitigation measures for the management of surface water and groundwater during works in or adjacent to watercourses that provide fish habitat; • Work in a manner that minimizes the risk of introducing silt, sediment, sediment-laden water, or any other deleterious substances into drainages, floodplains, ravines or storm sewer systems; • Work conducted in or adjacent to Bon Accord and Hawthorne creeks will be carried out during the least risk fisheries window (August 1 to September 15) (MoE 2006) unless approval to work outside this window is obtained from the regulatory agencies (MFLNRORD); and • An aquatic life salvage will be undertaken by Hemmera prior to any instream works. Aplin & Martin Consultants Ltd. Hemmera Erosion and Sediment Control Guidelines – 105A Avenue - 5 - December 2017 2.3.3.2 Work Near Aquatic Habitat All work activities must minimize the risk of introducing sediment-laden water, or any other deleterious substances into drainages, floodplains, creeks, ravines, or storm sewer systems. The measures and timing described below shall be employed during the construction activities in and around watercourses: • When not working within the wetted ditch of water courses, barriers must be installed along the riparian setback (10 m) of all drainages within the work space or drainages that are downslope of the work space to prevent overland flow from the work space from entering a watercourse. These barriers may be moved as construction progresses; • Machinery must be operated from the channel bank, road or bridge surface; and • All fill materials must be inert, free of contaminants and placed so that they will not enter any drainage, floodplain, ravine, or storm sewer system. Bark mulch, hog fuel or other wood waste material will not be used within 30 m of any watercourse. 2.3.4 Water Management The Contractor is responsible for all water that leaves the confines of the work space to ensure any water entering aquatic habitat (from the work space) meets the water quality criteria. • The following options are available for the management/disposal of surface water: ▫ Infiltration: sediment-laden water may be pumped out of the work area to a designated site where it can infiltrate back into the ground. This method is typically only suitable for smaller volumes of water. Potential discharge sites include dry swales or ditches (that are not fish- bearing and do not connect to fish habitat, or a storm/sewer system), or stable vegetated areas, at least 30 m from any watercourse; and ▫ Detention Facilities: can be used to hold sediment-laden water and allow for settlement of suspended sediment from the water column. Detention facilities may include constructed sediment ponds, ground depressions or portable water tanks. The facility must provide appropriate residence time to allow settling of suspended solids. Residence time required is a function of sediment particle size. Water shall be stored until sediment has settled and can be released in accordance with the appropriate water quality discharge standards, or until it can be otherwise transported off-site for disposal. The following information pertains specifically to water management criteria: • The Contractor is responsible for all water leaving the work space, access roads, and laydown areas; • Only clean water (i.e., less than 60 NTU or 75 mg/l TSS) may be discharged to aquatic habitat; • Sediment-laden water (i.e., greater than 60 NTU or 75 mg/l TSS) must be discharged to: ▫ A vegetated location at least 30 m beyond the top of bank that does not allow surface flows back into the work area (proposed infiltration zones are shown on the ESC Diagram (Attachment A)); Aplin & Martin Consultants Ltd. Hemmera Erosion and Sediment Control Guidelines – 105A Avenue - 6 - December 2017 ▫ A detention facility (constructed sediment containment pond) approved by the ESC Supervisor; and ▫ A portable storage tank (e.g., a large container) that can be moved along as construction progresses. • A sample measuring greater than 60 NTU must be sent to a lab for TSS analysis. If water quality exceeds either 60 NTU or 75 mg/l, additional mitigation must be implemented immediately until compliance with water quality criteria is restored. 2.3.4.1 General Best Management Practices • Construct sumps or install other flow moderating structures to allow collection, containment, and settlement of suspended sediment if sediment-laden water is generated; • Where practical, pump sediment-laden water to stable (i.e., erosion resistant) vegetated areas for infiltration to the ground and ensure that sediment-laden water does not enter a watercourse or storm sewer system; • Keep a back-up pump and fuel on-site in case of mechanical failure or an increase in flow; and • Any time water is being pumped to a new location, the discharge site should be approved by the QEP. Regularly monitor the discharge site to ensure that erosion, flooding, or unwanted pooling does not occur. Place an erosion resistant material on the ground at the discharge site to dissipate energy and prevent erosion. If erosion occurs, suspend dewatering activities as needed in order to implement ESC measures, reduce the flow, or move the site of discharge to a more appropriate location. 2.3.4.2 Rut Management Rutting from machinery and vehicles accessing the site may result in sediment-laden water leaving the work space. Saturated and soft soil, particularly in the vicinity of the peat south of the picnic area, is prone to rutting which may become a preferential pathway for water and may create mud bog conditions. Best management practices include: • Restricting access to the peat bog area; • Minimize rutting from vehicle traffic to prevent consolidation of surface water runoff and soil erosion; and • Use of work pads (Table 1) to create stable and non-rutting work surfaces. In addition, gravel should be stockpiled on-site in case of rutting or movement of water through preferential pathways. In this case, gravel will be used to create velocity check dams with the following specifications: • Composed of clean crush rock (75 mm to 150 mm) installed to slow the water velocity and control erosive energy. Alternative check dam products may be used, but must be approved by the ESC Supervisor prior to installation (e.g., straw bales are not to be used as check dams). Design and installation of check dams will follow accepted industry standards (Figure 3): ▫ Flow velocity < 1.5 m/s; Aplin & Martin Consultants Ltd. Hemmera Erosion and Sediment Control Guidelines – 105A Avenue - 7 - December 2017 ▫ Slope < 9%; ▫ Rock size 75 to 150 mm, but larger rock may be needed if flows displace rock; and ▫ The rock check dam must extend up the slope to the top of the swale on each side to prevent erosion around the edges of the check dam. ▫ Spacing of check dams on a uniform slope will be determined according to the following formula (Fifield, 2004): ▪ D = 100 x H / Z where: • D = distance between bottom of uphill dam to top of downhill dam • H = height of dam • Z = slope Spacing of check dams (or barriers) on varying slopes will be determined according to Figure 2: Aplin & Martin Consultants Ltd. Hemmera Erosion and Sediment Control Guidelines – 105A Avenue - 8 - December 2017 Figure 2 Barrier spacing in small drainage channels (Fifield, 2004) Aplin & Martin Consultants Ltd. Hemmera Erosion and Sediment Control Guidelines – 105A Avenue - 9 - December 2017 Figure 3 Rock Check Dam Typical Drawing (Alberta Transport, 2003) Aplin & Martin Consultants Ltd. Hemmera Erosion and Sediment Control Guidelines – 105A Avenue - 10 - December 2017 2.4 GROUNDWATER MANAGEMENT Groundwater may be removed off-site for disposal or discharged to ground as long as water quality criteria are met (Section 2.2.4). If a pond is used for containment, the following BMPs will be followed: • Sediment containment ponds will be constructed with a design that will allow the highest variety of soil particle sizes (i.e., larger than a medium silt) to settle out of suspension. Sediment containment ponds will not trap 100% of suspended sediment. Ponds have an efficiency ranging from 50 – 80%, based on size of pond (i.e., residence time), and may need mechanical filtering devises or chemical agents (flocculants) to achieve the desired water quality criteria (Malaspina University 2004). • Industry standards state that sediment containment ponds should be designed by a Professional Engineer because, if not designed or maintained properly, a sediment retention pond can lead to the release of large quantities of fine suspended sediments into receiving waters. • General construction/installation requirements for sediment containment ponds are as follows (Malaspina University 2004): ▫ Ponds size, configuration and features will be determined based on particle size and the appropriate retention time needed to provide suitable treatment; ▫ Ponds will be designed to maximize flow path length (i.e., residence time) and will have a length to width ratio of at least 6:1; ▫ Ponds must be installed prior to the start of onsite soil disturbance; ▫ Ponds may not be located within riparian areas, environmentally sensitive areas, or existing watercourses; ▫ Ponds should be accessible for maintenance; ▫ The embankment slope angle should be a maximum 2H;1V with a compaction rate of 95% Standard Proctor maximum dry density; ▫ Interior and exterior embankments should be covered with topsoil, seeded and mulched, or covered with gravel, riprap or polyethylene sheeting immediately after construction to prevent erosion of the pond banks; and ▫ An emergency spillway should be constructed to pass flows not carried by the principle outlet. The spillway must be an open channel over undisturbed or vegetated ground or be stabilized with appropriately sized rock and be a minimum 150 mm below the crest of any embankment. • Sediment containment ponds will be inspected after each rain event and any deficiencies, such as embankment erosion, must be corrected immediately. Water quality will be monitored frequently, especially turbidity and temperature, to ensure compliance with water quality criteria; and • Accumulated sediment should be removed from the pond prior to the storage capacity reaching 50%. 2.5 ENVIRONMENTAL MONITORING OF ESC MEASURES The Contractor is responsible for appointing an Environmental Monitor for the project. The City of Surrey ESC Bylaw requires the construction site is visited once per week during the winter (defined as the wet months between late September and early June) by the ESC Supervisor or their designated Environmental Monitor. The frequency may be modified based on weather, construction activity, and site performance. Aplin & Martin Consultants Ltd. Hemmera Erosion and Sediment Control Guidelines – 105A Avenue - 11 - December 2017 During the summer (defined as the dry months between late June and early September), the site will be inspected biweekly. Additional site visits are required during or within 24-hours of a significant rainfall event (City of Surrey 2009). Water leaving the work space that is discharged to aquatic habitat will be monitored by the Contractor daily to ensure the water quality conforms to the bylaw criteria (Section 2.2.4). The Environmental Monitor will work closely with the Contractor to ensure proper implementation, regular inspection and ongoing maintenance of all ESC measures, according to the City of Surrey Monitoring and Reporting Requirements for ESC Permitted Sites (2012). 2.6 EROSION AND SEDIMENT CONTROL SUPERVISOR The proposed ESC Supervisor will be Caroline Astley, a Registered Professional Biologist with over 10 years of construction experience in BC. The role of the ESC Supervisor will be to provide expert guidance and support to the Environmental Monitors and Contractor related to ESC and water management. 3.0 REPORTING As per the ESC Bylaw, the ESC Supervisor, or their delegate, will be responsible to submit weekly ESC reports to the City of Surrey Online ESC Supervisor Portal. Reporting frequency will be determined by site visit frequency (Section 2.3). Reports will also be submitted following a “significant rainfall” (i.e., at least 25 mm in a 24-hour period). The City of Surrey Rain Gauge will be used to determine rainfall amounts over each 24-hour period. 4.0 CLOSING This ESC Plan was developed to meet the requirements for ESC on sites larger than 2,000 m2 in the City of Surrey.
