3 December 20, 2012 The Municipal Infrastructure Group Ltd 8800 Dufferin Street, Suite 200 Vaughan, Ontario L4K 0C5 Attention: Angela Carley Reference: Peel Zone 5 Sub Transmission Main, Preferred Route Impact Assessment, Brampton, ON 1.0 Introduction Savanta is assisting The Municipal Infrastructure Group in assessing potential impacts to Natural Heritage features related to a Class Environmental Assessment for the Zone 5 Sub-transmission main. Savanta has conducted both terrestrial and aquatic assessments, which has included breeding bird surveys, an aquatic habitat assessment, and Ecological Land Classification/ botanical surveys to assess the potential impacts to natural heritage features, either directly or indirectly, associated with the installation of the watermain along the preferred route (Figures 1 and 2). In this report, the Right-of-way along Williams Parkway, as well as potential staging areas in the immediate vicinity of the watercourse crossing areas are hereafter referred to as the ʻSubject Landsʼ. The following summarizes the results of the field work and highlights potential constraints, as well as recommends which side of the road is likely to result in the least ecological impacts. 2.0 Vegetation Communities Botanical investigations were carried out on October 12 and November 9, 2012, under good fall conditions. During the field survey, vegetation communities were sampled using the protocol of the Ecosystem Land Classification (ELC) for Southern Ontario (Lee at al. 1998). Species names generally follow the nomenclature of Flora Ontario (University of Guelph, FOIBIS website). The Subject Lands are primarily composed of cultural meadows and mowed lawn along the right-of-ways of Williams Parkway. Wetland communities including cattail shallow 58 Welstead Drive, St. Catharines, ON L2S 4B2 Voice

4 marsh, reed canary grass meadow marsh, and forb meadow marsh surround the watercourses that cross Williams Parkway. The ELC types occurring on the Subject Lands are succinctly described in Table 1. Table 1. Ecological Land Classification (ELC) Vegetation Types ELC Type Cultural Cultural Meadow CUM1-1 Dry-Fresh Old Field Meadow Type Community Description This community occurs at Watercourse Crossing Numbers 1, 4, 6, as well as within a large field that occurs on the south side of Williams Parkway, immediately west of the Mount Pleasant Transformer Station located on the west side of Chinguacousy Road. The dominant species in the herb layer are tall goldenrod, New England aster, and awnless brome, with occasional sweet-scented bedstraw, reed-canary grass, wild teasel, tufted vetch, bitter nightshade, common burdock, wild carrot, and bird s foot trefoil. The shrub layer is very sparse, with occasional Tatarian honeysuckle, common buckthorn, red-osier dogwood (some of which is planted), and fewer stems of chokecherry, staghorn sumac, and riverbank grape. The old field meadows located at the watercourse crossing areas have scattered planted saplings of common species such as eastern white cedar, white pine, Freeman s maple, red oak, and trembling aspen. Scattered natural saplings of reddish willow and Manitoba maple occur within the majority of the old field meadows, including the large field located west of Chinguacousy Road. Cultural Thicket CUT1-7* Deciduous Cultural Thicket Marsh Meadow Marsh MAM2-2/ MAM2-10 Reed Canary Grass Mineral Meadow Marsh Type/ Forb Mineral Meadow Marsh Type This unit is located on the north side at Watercourse Crossing 7, and is dominated almost entirely by various tall shrubs, most of which are planted. The canopy layer is sparse and consists of Russian olive and common buckthorn, while the shrub layer is more dense and comprised of reddish willow, Manitoba maple, green ash, trembling aspen, fragrant sumac, red-osier dogwood, sandbar willow, and Tatarian honeysuckle. The dense herb layer consists of common species such as tall goldenrod, garlic mustard, tall white aster, awnless brome, and variable crown vetch. This meadow marsh complex surrounds the creek within the floodplain area at Watercourse Crossing Number 1. The MAM2-2 community is dominated by reed-canary grass, followed by jewelweed, and fewer numbers of tall goldenrod, spotted Joe-pye weed, garlic mustard, and common burdock. The MAM2-10 community is dominated by tall white aster, with fewer numbers of tall goldenrod, swamp aster, New England aster, and wild carrot. File: Peel Zone 5 Sub Transmission 2

5 ELC Type MAM2-2 Reed Canary Grass Mineral Meadow Marsh Type Shallow Marsh MAS2-1 Cattail Mineral Shallow Marsh Community Description This meadow marsh grows in a narrow riparian floodplain within the undefined creek bed at Watercourse Crossing Number 3. The community is dominated by reed-canary grass with occasional tall goldenrod, tall white aster, glaucous and narrow-leaved cattail, and swamp aster. A small inclusion of MAS2-1 cattail mineral shallow marsh occurs at the northwest corner of the intersection. This marsh unit occurs at Watercourse Crossing Numbers 2 and 5, and is dominated by glaucous and narrow-leaved cattail, with fewer numbers of reed-canary grass, wool-grass, tall white aster, purple loosestrife, and water speedwell. The community located at Watercourse Crossing Number 2 has a small inclusion of MAM2-2 Reed canary grass meadow marsh growing along the edge of the MAS2-1 community. The embankments leading down to the creek are disturbed CUM1-1 and have planted Eastern White cedar, red-osier dogwood, snowberry, and a few saplings of red maple. The community located at Watercourse Crossing Number 5 has scattered Russian olive, Manitoba maple, and staghorn sumac growing on the north side of Williams Parkway. *Denotes a type not listed in Southern Ontario ELC Guide 3.0 Flora Seventy-eight species of vascular plants were recorded from the Subject Lands. Of that number, 41 (or 53%) species are native and 37 (or 47%) species are exotic. The high percentage of non-native species reflects the disturbed nature of the vegetation communities growing along side Williams Parkway. Forty (or 98%) of the native species are ranked S5 (Secure common, widespread and abundant in Ontario), while one species (or 2%) was ranked S4S5, indicating a range of uncertainty of the species. The range is from S4 (Apparently Secure uncommon but not rare; some cause for long-term concern due to declines or other factors) to S5 (described above). No nationally or provincially rare or endangered plant species were recorded from the Subject Lands. Three locally rare species were found. Eastern red cedar (Juniperus virginiana) is provincially secure (S5) and common throughout southern Ontario. This species was observed as a planting along the ditch/ embankment in several spots. Snowberry (Symphoricarpos albus) is provincially secure (S4S5) and common throughout southern Ontario. The species was observed as plantings along several embankments. Sandbar willow (Salix exigua) was observed growing within the floodplain areas of several of the watercourses within the vicinity of the watercourse crossings. This willow is provincially secure (S5) and common throughout southern Ontario. In Savantaʼs opinion, none of the File: Peel Zone 5 Sub Transmission 3

6 above-mentioned species are considered a conservation concern. A list of all observed plant species is found in Appendix A. The Ministry of Natural Resources (MNR) Species at Risk (SAR) screening letter (April 11, 2012; Appendix B) noted Butternut as a potential SAR for the Subject Lands. Targeted searches for Butternut were conducted but the species was not found. 4.0 Aquatic Resources All of the watercourses in CVC jurisdiction (Huttonville Creek, Springbrook Creek, Tributary 8b, and Fletcherʼs Creek) have been identified as providing habitat for Redside Dace. Redside Dace is protected under the Endangered Species Act (2007) and each of these watercourses is considered to comprise regulated habitat for this species. In TRCA jurisdiction, there are two watercourse crossings (Etobicoke Creek and a tributary of Spring Creek). An information request has been submitted to TRCA as to whether these watercourses have been identified as providing habitat for Redside Dace. For the purposes of this report, Savanta will assume both watercourses are regulated habitat for Redside Dace. The proposed use of trenchless technologies for all watercourse crossings (Figure 3) will provide the ability to avoid direct impacts to these watercourses, however, the potential for dewatering during the construction phases and the requirement to discharge this water must also be addressed. The use of trenchless technology at all watercourse crossings, along with a robust mitigation plan, will likely result in the ability to work with the MNR in approving these works under a Letter of Advice (LOA). An Information Gathering Form will be submitted to MNR so they can assess the scope of works and make a determination as to whether the proposed works have the potential to create any impacts, either directly or indirectly, to this species. Regardless, the fact that the watercourses are regulated habitat for Redside Dace will mean that the construction will be prevented between July 1st and September 15. Aquatic habitat was assessed on October 12, The results are following: Huttonville Creek The bankfull width ranged from 2-4m, and bankfull depth was approximately 0.25m. Flow depths ranged from 15cm to 30cm in a couple of deeper pool areas. The creek bottom is covered with gravel, stones, and some sand. Dense riparian vegetation includes reed-canary grass, jewelweed, tall white aster, and tall goldenrod. Several reddish willow and green ash were also growing near the creek. Approximately 20 small minnows were observed, and no barriers to fish movement were found. The creek was exhibiting riffle and pool morphology. A small farm crossing that included a concrete 2m span open-bottom bridge was observed under the larger span bridge. File: Peel Zone 5 Sub Transmission 4

7 Springbrook Creek The bankfull width is approximately 15m, and bankfull depth is approximately 1m. The creek is a braided channel through dense cattails, with flow depths ranging from 5 to 10cm. The creek bottom is covered with muck. Dense riparian vegetation includes cattails and reed-canary grass, with small, planted shrubs of eastern white cedar and dogwood growing along the embankments. The creek travels through a large concrete open-bottom span bridge approximately 5m in width. No fish were observed. The dense cattails could serve as a barrier to fish movement, although at periods of high water levels, this is likely not an issue. Tributary 8b The bankfull width is approximately 8m, and bankfull depth is approximately 1m. The creek channel is dry bare soil, but is rock-lined at the culvert crossing. Dense riparian vegetation includes reed-canary grass, tall white aster, swamp aster, cattails, and tall goldenrod, with planted saplings of eastern white cedar, balsam poplar, and red maple growing along the embankments. The creek travels through a large concrete open-bottom span bridge approximately 5m in width. No fish or fish barriers were observed. Main Branch of Fletcherʼs Creek The bankfull width is approximately 5m, and bankfull depth is approximately 1m. Flow depths ranged from 20cm to 40cm in a couple of deeper pool areas. The creek bottom is sand and silts covered with scattered gravel and stones. Dense riparian vegetation includes tall goldenrod, New England aster, common reed, garlic mustard, and reed canary grass. Scattered reddish willow, Manitoba maple, and Freemanʼs maple were also growing along the edge of the creek. No fish were observed, and no barriers to fish movement were found. The creek flows under a large open span bridge approximately 20m wide. A large amount of refuse was observed at the creek crossing location. East Tributary of Fletcherʼs Creek The embankments of the creek are lined with concrete, and the creek channel is approximately 2m wide and choked with cattails. Flowing water approximately 5-10cm in depth was observed. Additional riparian vegetation is limited to reed-canary grass, as well as several Russian olive, Manitoba maple, and sumac shrubs growing along the embankments on the north side of the road. On the south side of the road, young buckthorn, green ash, and willow grow. The creek travels through a large concrete open-bottom span bridge approximately 5m in width. No fish were observed. Dense cattails could serve as a barrier to fish movement, although at periods of high water levels, this is likely not an issue. File: Peel Zone 5 Sub Transmission 5

8 Etobicoke Creek The bankfull width ranged from 3-4m, and bankfull depth was approximately 1m. Flow depths ranged from 0.4m to 0.75m in the deeper pool areas. Immediately at/ underneath the bridge, the creek lined with cement and rocks. Further away, the creek bottom is natural and consists of gravel, stones, and some sand and silts. Dense riparian vegetation includes reed-canary grass, Kentucky bluegrass, crown vetch, and tall white aster. Several mid-age trees and shrubs such as Russian olive, buckthorn, Norway maple, and sumac grow along the embankments. In general there is less vegetation north of the road compared to the south side. Approximately 30 small minnows were observed, and no barriers to fish movement were found. The creek crosses under a wide (approximately 30m) span bridge. South of the road, on the west side of the creek, two large corrugated steel pipes drain into the creek. Still on the west side of the creek, but north of the road, a large manhole is present within the embankment. Tributary of Spring Creek This section of Williams Parkway has a very wide manicured lawn Right-of-way on both sides of the road. In the vicinity of the watercourse crossing, on the north side of the road, the creek flows through an open storm water sewer (concrete bottom), and is fully piped on the south side of Williams Parkway for approximately 65m before it passes under Leacrest Street and becomes an open channel again. On the north side of Williams Parkway, the embankments leading down to the creek are also lined with concrete. The channel is approximately 1m in width, and flow depth was approximately 20cm. Scattered gravel and stones were observed along the bottom of the concrete sewer. Riparian vegetation consists of a cultural thicket dominated by mostly planted shrubs including willows, Russian olive, green ash, red-osier dogwood, and fragrant sumac. Riparian herb cover includes tall white aster, awnless brome, and garlic mustard. No fish or barriers to fish movement were observed. The watercourse flows under WiIliams Parkway in a large corrugated steel pipe culvert. As mentioned above, on the south side of the road, the watercourse is fully piped. The Right-of-way is very wide and consists of manicured lawn. 5.0 Breeding Birds Breeding birds were surveyed on June 17, 2012 in accordance with the methodology developed for the Ontario Breeding Bird Atlas program. Two Point Count Stations were established to provide coverage of all habitats present (Figure 4). At each station all birds seen during the five-minute count were recorded as occurring within or beyond 100m. Surveys were conducted between 0500 and 0745h under calm, warm conditions. File: Peel Zone 5 Sub Transmission 6

9 A total of 10 species of birds were noted on the Subject Lands, of which 9 showed some evidence of breeding (5 Confirmed and 4 Probable), while one species was believed to be visiting the site but not breeding there. The full list of bird species including comments is found in Appendix B. The species present are generally typical of the habitat available. The preferred route is lined with residential housing and was found to be unfit for ground nesting birds. Most natural areas are city park environments with manicured lawns. Three naturalized areas from Chinguacousy Road to Mississauga Road where migratory birds were noted included PC1, PC2, and the large cultural meadow located just west of Chinguacousy Road. However, there is no expected impact on ground nesting birds along the right-ofway, or for birds that would use trees and shrubs for nesting, since better quality nesting habitat at these locations is situated well away from the right-of-way. As well, the proposed watermain installation at the watercourse crossing areas associated with PC1 and PC2 will be conducted by tunneling under the watercourse. This will result in minimal disturbance to the habitats surrounding the watercourses, and only minimal additional noise impacts compared to that created by current traffic and construction activities occurring in the general area. The bridge over Huttonville Creek, just northeast of Mississauga Road, was the site of a nesting colony of Barn Swallows, with six active nests observed underneath the bridge. The bridge is new and approximately 90m long and four lanes (20m) wide. As noted above, the proposed watermain will be installed by tunneling under the creek. On the west side, the currently proposed shaft and staging area is just east of the road (15m west of the edge of the bridge) in an existing green space at the top of bank. On the east side, the currently proposed shaft and staging area is approximately 30-50m east of edge of the bridge. Machinery will be within the staging areas, and there should not be a need for machinery to be placed under the bridge. Silt fencing (or equivalent) will be installed at the work limits. The generator for the tunneling will be the main source of noise. Immediately at the generator the noise level is typically 65db. At approximately 15m from the generator, the noise level is comparable to street noise. Therefore, the expected additional noise levels created by the tunneling activity and associated machinery will be similar compared to that created by current traffic and construction activities occurring in the general area. In Savantaʼs opinion, the only disturbance to the Barn Swallows will be some extra noise, however the existing traffic on Williams Parkway, as well as current construction activities in the general area, will mask the majority of any extra noise created by the tunneling activity. An Information Gathering Form will be submitted to MNR to determine if the watermain installation must occur outside of the barn swallow breeding season (Late May - Mid July). There are no other structures within the Subject Lands that would provide nesting habitat for this species. File: Peel Zone 5 Sub Transmission 7

10 One Barn Swallow was observed foraging over a storm water pond located at Watercourse Crossing Number 3 where it was taking advantage of the insects coming off the water. This bird was not displaying breeding behaviour and there were no suitable nesting structures in the immediate area. The proposed watermain installation would likely not prevent the bird from foraging over the pond as it is approximately 25m from the road, however Savanta acknowledges the construction activity may cause the bird to forage over some open fields to the southeast, where housing developments have not yet been built. MNR Aurora district office noted (April 11, 2012; Appendix B) that Bobolink (Threatened), Chimney Swift (Threatened), and Eastern Meadowlark (Threatened) might also occur in the vicinity of the study area. MNR also noted historical records of Cerulean Warbler (Threatened) and Red-headed woodpecker (Special Concern). None of the species were observed during the Savanta surveys. Chimney Swift mainly nest in man-made structures such as large open chimneys of older homes, which do not exist on the Subject Lands. The chimneys of the new housing along Williams Parkway would have modern inserts that are not suitable habitat for the species. Bobolink requires large open areas of grassland or hay fields for breeding habitat. The majority of the cultural meadows within the Subject Lands are small areas along embankments at the watercourse crossings, which are too small for Bobolink. However, a larger cultural meadow occurs at WC1 (PC1) and within the large field just west of Chinguacousy Road (PC2). No Bobolinks were observed there despite careful searches. This species is easily located where they nest so their absence here is real, possibly due to the high forb content of the old-field meadows. Eastern Meadowlarks are found in grassland habitats ranging from native prairie to abandoned fields and active pasture. The species was not observed, suggesting the oldfield meadows within the Subject Lands are too far along in succession. Similar to Bobolink, Eastern Meadowlark is easily located where they nest, so their absence is real. It is also important to point out that the survey date of June 17 is an ideal time to survey for both Eastern Meadowlark and Bobolink. Cerulean Warblers are forest-interior birds that require large, relatively undisturbed tracts of mature, semi-open deciduous forest. This habitat does not occur on, or in close proximity to, the Subject Lands. Red-headed woodpecker habitat includes open woodland and woodland edges, especially in oak savannahs and riparian forest, which contain a higher density of dead File: Peel Zone 5 Sub Transmission 8

11 standing trees, which they commonly use for nesting and perching. The woodpecker has declined dramatically over the past decade, and despite searches it was not observed. Savanta acknowledges that the ESA surrounding Huttonville Creek is forested approximately 100m north of the bridge at PC1, and approximately 70m south of the bridge at PC1, and that these riparian forests could provide habitat for the species. Regardless, any pairs nesting in proximity to the bridge would be sensitized to the traffic noise from Williams Parkway, and any additional construction noise is expected to be minimal and would not be expected to disturb the species. American Kestrel may be a candidate for a federal Species at Risk designation, and was observed during Savantaʼs bird survey at PC2 in the large old field meadow just west of Chinguacousy Road. The bird was not displaying breeding behviour, but was a visitor in the field, likely foraging. American Kestrel nests in tree cavities and would not use the old-field as nesting habitat. The species is often found perching on power lines along side roads to hunt, and any extra noise from the watermain installation will not likely prove a major disturbance. Many of the birds observed on or near the Subject Lands are protected under the Migratory Bird Convention Act. However, due to the mix of cultural habitats and the relatively small, linear, area of potential impact, Savanta is of the opinion that the construction-timing window of the Migratory Bird Convention Act is not warranted in this situation. 6.0 Reptiles MNR Aurora district office noted that Milksnake (Threatened) and Snapping Turtle (Special Concern) might also occur in the vicinity of the study area. Therefore, reptiles were surveyed in conjunction with ELC/ botanical surveys, on October 12, 2012, and involved surveying all watercourse crossing areas, including creek banks, basking logs, and rock piles/ debris piles. Three ponds (natural and SWM ponds) located in close proximity to Williams Parkway were also surveyed for reptiles: 1) small naturalized pond just west of Elbern Markell Drive, on the south side of Williams Parkway; 2) large SWM pond immediately west of James Potter Road and close to WC3 (Figure 3), on the south side of Williams Parkway; and 3) large naturalized pond in Major Oaks Park, located just west of Highway 7, on the north side of Williams Parkway. Because Snapping Turtles do not generally bask, this species was also surveyed by searching for egg nests within any suitable gravel areas in proximity to the watercourse crossings and ponds. In the same areas, road-killed reptiles were also searched for along the shoulders on both sides of the road. Milksnake was also searched for in the large old-field meadow at PC2 by walking four transects through the field. Weather was optimal for observing reptiles, with clear, sunny skies, temperature of 10 degrees Celsius, and light winds. File: Peel Zone 5 Sub Transmission 9

12 Despite significant effort within the existing semi-natural areas, no reptiles were observed. This is not surprising given the high density of houses and traffic/construction noise/ vibration occurring on Williams Parkway. In Savantaʼs opinion the fact that the watermain will be installed within the Right-of-way, and because watercourse crossings will be conducted using trenchless technologies, suggests that only minimal, if any disturbance would occur if these species were present. Very small areas of habitat loss at the construction staging sites would occur, and as described in Section 5.0, additional noise from the tunnelling activity will be minimal and compare to existing traffic noise. Any reptiles occurring in close proximity to Williams Parkway would already be tolerant to considerable noise vibration from the existing traffic, and as such the proposed watermain installation is not expected to impact any reptile species. As well, the roadway and right-of-way/ shoulders where the watermain is proposed to be installed are significantly higher in elevation compared to all of the watercourse crossing areas and ponds, where any reptiles would be expected to occur. This further suggests that the proposed construction will not impact any reptile species. 7.0 Wildlife Habitat The majority of the Subject Lands consist of mowed lawn and cultural meadow within the right-of-way of a busy road, which appears to have little obvious habitat of importance to wildlife. The most notable habitats along the route are the various wetland/creek crossings, ponds, and large old-field meadow located adjacent to Williams Parkway. All of the watercourses that cross Williams Parkway have some degree of riparian vegetation that would provide cover for wildlife movement. The watercourses with the most riparian vegetation, thereby providing the best linkage capability, are Huttonville Creek and Etobicoke Creek. In the vicinity of Williams Parkway, both of these creeks contain ʻWoodlandʼ as mapped by Region of Peel. Furthermore, the crossing at Huttonville Creek (WC1) is mapped as an Environmentally Sensitive Area (ESA). WC1 was the only watercourse crossing area to have mammal tracks recorded, which included white-tailed deer, northern raccoon, and coyote. For all of the watercourse crossings, the proposed construction activity associated with the watermain installation will be within the right-of-way, and is not expected to have any measurable impact to adjacent wildlife habitat, with the exception of some construction noise. However, Williams Parkway experiences high traffic and so most wildlife would be adjusted to road noise. Three ponds are located within close proximity to the Subject Lands. The first is a small, naturalized pond just west of Elbern Markell Drive, approximately 35m south of Williams Parkway. This pond is surrounded by cattails and scattered shrubs, and would provide some habitat for wildlife such as small mammals and amphibians. This pond is far enough from Williams Parkway that the proposed construction activity would not likely impact any wildlife here. The second pond is a large SWM pond immediately west of File: Peel Zone 5 Sub Transmission 10

13 James Potter Road, approximately 20m south of Williams Parkway. This pond has shrubs and riparian vegetation such as cattails growing along the embankments, and would also provide some habitat for small mammals and amphibians. Although the likelihood of the proposed construction impacting any wildlife here is low, if possible, it would be beneficial to install the watermain on the north side of the Williams Parkway to avoid this feature and associated habitat. The third pond is a large naturalized pond in Major Oaks Park, located just west of Highway 7, approximately 40m north of Williams Parkway. This feature is also surrounded by riparian vegetation and would provide some habitat for small mammals and amphibians, however it is far enough away from Williams Parkway such that the proposed construction would not likely impact any wildlife here. A large old-field meadow occurs just west of Chinguacousy Road, immediately south of Williams Parkway. Small mammals would certainly use this field as habitat, however, they likely stay clear of Williams Parkway due to the high volume of traffic, or have become accustomed to the noise. As such, the proposed construction would not likely provide any further disturbance. 8.0 Recommendations Preferred Side of Road Moving in a west to east direction, Savanta recommends the following preferred side of road for the watermain installation, in order to minimize ecological impacts. It is important to note that in all cases, in Savantaʼs opinion either side of the road is acceptable, as potential impacts to natural heritage features are indirect and minimal. Mississauga Road to James Potter Road The preferred side is the north side as this minimizes impacts to the wooded feature surrounding Huttonville Creek, as well as the two ponds in close proximity to Williams Parkway. James Potter Road to McLaughlin Road The preferred side is the south side as a portion of Tributary 8b runs adjacent on the north side of Williams Parkway for approximately 400m (from James Potter Road to the railway line). McLaughlin Road to Southlake Boulevard The preferred side is the north side as a portion of Fletcherʼs Creek runs adjacent on the south side of Williams Parkway for approximately 680m (from McLaughlin Road to WC5). As well, there is less vegetation on the north side of crossing of Etobicoke Creek. Southlake Boulevard to Dixie Road The preferred side is the south side to minimize any potential impacts (although highly unlikely) to the pond located in Major Oaks Park. As well, the tributary of Spring Creek is File: Peel Zone 5 Sub Transmission 11

14 fully piped on the south side of Williams Parkway, and the only vegetation in the area is manicured lawn. Yours truly, Savanta Inc. Savanta Inc. Richard Hubbard, Vice President George Buckton, Ecologist File: Peel Zone 5 Sub Transmission 12
