SITE ANALYSIS

KOSTIUK PELZ WILLIAMSON PHONE: 1-519-546-8561 EMAIL: [email protected]

ROADSThe site is south of County Road 124 and west of Highway 6, the Hanlon. It is located southeast of Guelph.

LAND-USE

Most of the surrounding land use is agricultural. There is also a large park area northeast of the site and following the Speed River. On the outer edges of Guelph, closest to the property is a large area of residential zoning.

DEPTH TO WATER TABLEThe water table is very close to the surface on the south and east portions of the site as it nears the Speed River.

CONTOURThe site is located in a low point relative to the surroundings. The surrounding area has very little variance in elevation. As the map shows, there is a difference of just over 100m across this region.

SOILS

Most of the soil on site is a fertile loam. Much of the soil surrounding the site is also loam that is excellent for agriculture.

VEGETATION AND HYDROLOGY

The site is located adjacent to the flood plain with some overlap in the southern portion. Vegetation in the surrounding context is very patchy. The largest patches of vegetation are located within the riparian zone (floodplain). However, there are also several patches with smaller gaps. There is opportunity on the site to create alternate routes for fauna traversing the gaps in the vegetation.

River Watch sites are used to monitor the Speed River and collect data about water levels and quality. There are two Grand River Conservation Authority river watch sites in very close proximity to the Guelph Plant site.

LOCATION The Guelph Plant property lies over the border between the City of Guelph and the Township of Puslinch. Its 141 hectares stretch south to the floodplain of the Speed River and east to just beyond Whitelaw Road. While its neighbours to the north include mainly industrial or commercial shops, much of the surrounding landscape is zoned agricultural. There are a few residential lots adjacent to the site along its northern boundaries. Care must be taken to reduce the effects of noise, dust and vibrations for these residents.

CONTEXT The site follows the contours of the Speed River, which offers unique challenges and opportunities. Between the property line and the river, and in some places crossing the property line, is a riparian zone composed mainly of Eastern White Cedar. There are significant vegetation gaps in this zone and improving the connection across them would greatly benefit local wildlife. While the City of Guelph is nearby, the zoning west of the Hanlon is primarily residential in built areas. The Guelph Plant site is easily accessible from County Road 124 along the existing haul road. As the material extraction will extend below the water table, the level of the water table is assumed to be at an elevation of 298m. Much of the current site surface is between 305m and 320m above sea level. Given that extraction can occur up to 18m below the water table, the pit bottom will be at 280m before rehabilitation.

SITE The Guelph Plant is a sand and gravel pit and a dolomite limestone quarry, with concrete and asphalt recycling and processing on the property. There are two areas on site noted as being previously rehabilitated. However, these areas still have material of value to be extract-ed and so will be affected by future operations. The limit of extraction excludes the ‘Stonehenge’ site in the northwest portion of the Guelph Plant. Three settling ponds exist where sediment from the gravel washing process was deposited. The silt contained in these ponds is rich in minerals and can be used to enhance soils on site during the rehabilitation process. Along Whitelaw Road, there is a wire and post fence. Other fence placement was unconfirmed during ground-truthing due to the large size of the site.

OPPORTUNITIES• Site is close to existing amenities such as commercial

areas and City of Guelph roadways• Proximity to the Speed River strengthens opportunities to

increase biodiversity and habitat patch size• International Year of Biodiversity – site provides an

opportunity for Lafarge to showcase dedication to environmentally responsible excavation and rehabilitation procedures.

• Relatively thin overburden makes harvesting materials efficient

• Site shape provides an opportunity for ecologically focused phasing that considers adjacent riparian area

• Location near roadway offers opportunities for public interaction with the quarry once all phases are completed

• Excavation creates dramatic cliffs

DYNAMIC GROUNDWORK2PHASING

PHASING PLAN

DESIGN Rehabilitation begins with an agroforestry planting in area A. It is assumed from information provided on site that this area has no material for extraction and will remain at its present elevation. As the extraction process may continue on this property for fifty to one hundred years, there is an opportunity for high value trees to be planted that will provide wildlife habitat and forge in the present, and material for construction of proposed buildings on site in the final phase. Additionally, solar panels and wind turbines are installed at the onset to provide power to extraction infrastructure, with any extra being sold back to the grid.

EXTRACTION Initial extraction takes place in areas farthest from the main road, Wellington County Road 124, and closest to existing riparian habitat. Looking at the site in the larger context, there are two significant gaps in the forested corridor along the Speed River. One is in the City of Guelph and the other is adjacent to area B. By initiating extraction, and therefore rehabilitation, in areas B and C, Lafarge is able to narrow this corridor gap quickly. With areas B and C being farthest from the main haul road, once work in these sites is completed they can remain undisturbed for the remainder of the process. During extraction of area B, overburden will be stockpiled in area C, which is currently a relatively flat site that will allow quick and easy access. The final extraction elevation will be 18 metres below the water table to rest at 280m.

BIODIVERSITY The agroforestry operation in area A is planted with native species of high commercial value. This may include, but is not limited to, black cherry, black walnut, red and white oak, red and sugar maple, and white pine. While the stand is mixed to a certain degree, it is recommended that the black walnut species be clustered in a pure stand to prevent large areas of soil from being affected by Juglone, a natural plant toxin emitted by black walnut.

C

DESIGN The operation moves to area C and rehabilitation begins in area B. The goal for areas B and C is to have them provide shallow wetland habitat in keeping with the local surrounding landscape. With this in mind, the vertical rock faces remaining after extraction are collapsed using large hoe rams and other appropriate demolition machinery with a resulting slope of 4:1 or more gradual. Clean infill material to bring the pit close to surrounding ground level will need to be brought in initially and this may be sourced from demolition projects in the surrounding county. Because the extraction removes a large amount of material from the site, it is appropriate that other clean ‘waste’ material be brought in to replace it. Silt from the three settling ponds, and top soil from the berms, is used to top off the filled pit and prepare the site for planting.

EXTRACTION As area C is excavated overburden is moved to area B to fill the pit. This process of filling previously excavated areas with the overburden from current excavation is repeated throughout the site phasing. Excavation moves from the eastern side of the area to the west, using the haul road established in phase I to access area B. Extraction in area C does not extend into the current woodland to keep this area intact and protect the river from unnecessary runoff. As extraction in area C extents below the water table, assumed to be located at 298m, water is pumped from the pit floor and discharged into area B.

BIODIVERSITY The conversion of area B to a shallow wetland nearly closes all the gaps in the riparian corridor that follows the Speed River. This facilitates the movement or migration of fauna. As much of the current habitat is sparse and patchy, this connection is vital. The new wetland will filter water pumped from the excavation sites, allowing for gradual percolation through the soil to the Speed River. This also allows the water warmed by the extraction process to cool before entering the freshwater system. Plants will evapotranspirate some water back to the atmosphere so as not to overburden the river system.

C

DESIGN Extraction in area D brings the operation closer to the main haul road and allows the closure and removal of the haul road in area B, which includes decompacting the soil. Planting of wetland species over the filled pit and of pioneer forest species on the surrounding lands brings the site closer to its final rehabilitation. Area C begins to be filled with overburden from area D to bring it up to the same elevation as area B. In the end, these two zones will be primarily undisturbed areas with limited access for research purposes in order to separate human-use areas from wildlife habitat as much as possible. Cliffs in area C are collapsed as in area B to facilitate eventual wildlife access to the water.

EXTRACTION Area D is adjacent to the main infrastructure for processing materials which eases transportation. This is also the location of current stockpiles, which were used initially for the infill of area B, or could be used during this phase to backfill area C. As area C is to be similar in elevation to area B, overburden from areas D and E will be used to fill it, with supplementary clean fill from off-site as required. As material is extracted from areas D and E, water is pumped out and discharged into areas B and C.

BIODIVERSITY The building of shallow wetland habitat in areas B and C that is to remain undisturbed after rehabilitation creates one of the largest patches of habitat along this section of the Speed River. This will provide refuge and rest for fauna requiring interior habitat. In phase III area B is planted with vegetation that will act as biofilters, cleaning the water as it passes through to the Speed River. Native vegetation for the wetland includes sedges orchids, iris, dogwood, and willows, among others. For the forest plantings, species include alders, poplar, birch, pine, and fir. Large woody debris is placed along the shoreline and in the newly planted forest to add nutrients to the soil, and to create varied microclimates to aid in the growth of young plant material.

DESIGN Area E is the western-most zone, nearly surrounding the ‘Stonehenge’ property. The backfilling of area C is completed, followed by the addition of topsoil and plant material to match the wetland and forest habitats of area B. The haul road is closed and removed back to area D, where clean fill is needed to build up the islands. Other than the shallow slopes of the islands, cliffs generally remain around this pond, though they are stepped at varied intervals from 2 to 5 metres. Areas D and E are both kept as deep ponds to provide cold water habitat to aquatic species. The cliffs will be partially collapsed in the eastern portion of this area to ease the transition to the shallow wetlands.

EXTRACTION Final extraction will take place in area E, with overburden being used in the filling of area C and in the wetland connection between area C and the pond of area D. As in phase II, extraction is kept more than the minimum setback from the river, following the existing tree line.

BIODIVERSITY The high south facing cliffs of area D offer excellent opportunities for micro-habitat creation. A stepped and rough faced wall provides niches where water can pool; the stone can receive and radiate heat in small pockets; a crevice can provide shade and protection from the wind. In short, opportunities abound to attract a great diversity of flora and fauna. The islands offer protected nesting grounds for water fowl, away from the accessible edges of the wetlands.

DESIGN With extraction completed, finalizing the rehabilitation of the different areas is the priority. Rehabilitation of area E is similar to that of D, with the focus on creating micro-habitat opportunities in the south-facing cliffs. Another island, larger than those on area D, is built up in area E using imported clean fill before the area is allowed to fill with water. A connecting stream is opened up between the areas D and E to allow movement between the two. Haul roads are removed or allowed to be covered with water.

EXTRACTION Infrastructure is dismantled and removed from site. Components such as foundations and structures that will not be reassembled at other sites are used as clean fill where deemed appropriate. Access to the site from County Road 124 remains as the point of entry. The total area extracted covers 73 hectares.

BIODIVERSITY The two deep ponds and two shallow wetlands, the stepped, rough cliff faces, and the extended riparian forest provide diverse habitat for birds, fish, pollinators, and small mammals, and provide stronger continuity of native vegetation along the Speed River.

The trees planted in phase I have reached maturity. They are selectively harvested and milled for lumber to be used in the construction of the various proposed developments. Wood can also be sold to generate revenue. A LEED Gold standard conference centre is the central component of the design, with ecologically responsible surface parking and outdoor picnic spaces nearby. Paths tour the perimeter of the pond in area D with a bridge offering expansive views of both deep ponds and the surrounding cliffs. The path meanders as a boardwalk where the wetland narrows and drains into the larger pond. Trees harvested from the agroforestry area are replaced with new plantings of the same species selection so that they can be used in future construction, renovation, or restoration.

The rehabilitation design for the Guelph Plant, Dynamic Groundwork, celebrates 2010 as the United Nations International Year of Biodiversity by highlighting Lafarge’s commitment to environmental stewardship. Through a series of progressive rehabilitation phases, two wetlands and two deep ponds diversify the available habitat. Around the two deep ponds the design takes advantage of steep south-facing cliffs to create micro-habitats for a great diversity of native flora and fauna. These favourable microclimates increase thermal comfort, creating people friendly space. Finally, the scene is tied together with an open conference centre in place of the existing quarry infrastructure, its geometric form connecting it to the vertical faces of the cliffs. While the rental of the conference centre will provide revenue, human use is limited to the area surrounding the eastern pond so as to leave the majority of the site undisturbed after rehabilitation. A conference centre was chosen to add an amenity area for residents of Guelph living west of the Hanlon Parkway, who currently have little space for recreation. Current options for conferences held in Guelph include a few large hotels. The Guelph Plant site provides a scenic, memorable area removed from the busy activities of the city. Progressive rehabilitation of the site is phased from east to west, allowing the main haul road to be backed out as extraction of each defined area is completed. Overall, this design lays the groundwork for showcasing Lafarge’s commitment to environmental stewardship in the rehabilitation of pit and quarry sites.

Dynamic GroundworkThe Guelph Plant is a 141 hectare sand and gravel pit and dolomitic limestone quarry, with concrete and asphalt processing on site. Rehabilitation planning had to consider the bordering Speed River and its riparian zone, neighbouring residential and agricultural uses, extraction levels below the water table, and the dramatic cliffs resulting from extraction processes.

Capitalizing on the International Year of Biodiversity, the rehabilitation design highlights Lafarges commitment to environmental stewardship. A series of progressive rehabilitation phases result in two wetlands and two deep ponds to diversify the available habitat.The design takes advantage of steep south-facing cliffs to create micro-habitats for a great diversity of native flora and fauna. An open conference centre in place of the existing quarry infrastructure will provide revenue, though human use is limited to the area surrounding the eastern pond so as to leave the majority of the site undisturbed after rehabilitation.

While the group worked cohesively on the whole project, my focus was on the phasing process. Progressive rehabilitation of the site is phased from east to west, allowing the main haul road to be backed out as extraction of each defined area is completed. The wetlands created near the beginning of the process help cool and filter the water pumped from the continuing operations.

Intersections & Clarity

Landscape & Identity

Circulation & Safety Currently,cyclistsridewithtrafficbetween the Hanlon and Edinburgh, and close beside vehicles east of Edinburgh. Their differing speeds create a hazard for both. Buses pulling over at stops enter the bike lane, and pedestrians cross at multiple points along the road, often far from crosswalks.

College Avenue is wide and straight with a hill just east of Edinburgh, and a hill at Gordon Street. This open feel encourages drivers to travel above the speed limit increasing the danger of collision for all users, especially in front of the two high schools and the public school. With residences set far back from the road, and wide lots spacing buildings far apart, the area has low activity for people, but plenty of opportunity for natural elements.

Intersections are the most frequent location of collisions for all road users. The bike lane on College ends several meteres east of the intersection with Edinburgh, leaving both cyclists and motorists without clear direction. At the intersection of College and Gordon cyclists and motorists must cross paths in many situations, increasing the possibility for collisions to occur.

Thesis AbstractEconomically-oriented planning does not incorporate aesthetic preference, a key factor in an individuals decision making. This slows the adoption of new ideas, technologies, and behaviours that do not appeal to perceptual experience, though they may be based on valid knowledge. This paper explores the cause and effect relationships between experience, behaviour, and preference, and applies it to the negative impacts of car dominance to promote cycling as a sustainable transportation alternative. The aesthetic quality of a cycling network can either encourage or discourage its use and must therefore be integrated into the design. The solution, then, is in the process rather than in the product as user preferences must be obtained and incorporated. It is the physically-oriented, tangible elements such as infrastructure and spatiallayout, and the perceptually-oriented, intangible elements such as aesthetics, coherence, and perceived safety that are necessary to make the cycling network both useful and enjoyable.


Section A Hanlon to Edinburgh

Converting the two outside trafficlanestobikelaneswithcurbed bioswales not only increases safety for cyclists and motorists by separating their paths, but also encourages pedestrians to cross the street in designated areas. Where bus stops are available, pedestrian crossings are marked on bike lanes.

Circulation The fence keeps vehicles and bicycles on separate paths and makes pedestrian crossings more predictable. The recycled tires used to build the fence will absorb some of the impact should a collision occur, further protecting all road users.

The busy intersection at Scottsdale Drive is easier to navigate for all users when the lanes and crosswalks are clearly marked. The raised curbs are only necessary here on two corners. N

Section B Edinburgh to Smith

Shifting and expanding the road to the south allows for the inclusion of two bioswales. The boulevards are planted with meadowgrassesandwildflowersto compliment the imitation cedar rail fence. This long swath, visible along the whole section at once, gives the impression of a prairieoragriculturalfield.

Landscape The vegetated swale collectsrunofffromthetrafficand bike lanes and prevents the gravel and sand from collecting in the bike lane. At night, the road is illuminated by lighting along the fence, creating a visual rhythm.

Intersection The painted lanes at the intersections are protected at the corners by low concrete islands that keep right-turning vehicles outside the bike lane. Where motorists and cyclists cross paths they will be able to make eye contact to reduce confusion and reduce the risk of collision.

Straight Through the cyclist keeps to the outside of the intersection. If a vehicle is turning right, eye contact is possible where they meet

Design

Section A

1.5m 4.6 1.8 1.8 7.2 1.8 1.8 5.2 1.5

The final design contains four main elements - a bioswale separating the traffic and bike lanes, a rail fence made of recycled tires running the length of the bioswale, plantings along the boulevards, and intersections redesigned to minimize cyclists and motorists crossing paths.

The rail fence of recycled tires is both functional in separating the vehicles from the cyclists, and is also a sculptural piece that contributes to the agricultural feel of the journey. This provides an element of protection for cyclists and vehicles, and makes crossing the street safer as it directs pedestrians to cross at designated places. Solar lighting above the fence posts compliments the existing street lighting and creates a visual rhythm along the avenue at night. The swale that supports the rail fence and buffers the bike lane from traffic also functions as a filter for surface runoff.

The plantings in the bouldevards are one of two elements that create the agricultural feel for the site, reminiscient of the area s rural past.

At the intersection existing bike lanes are shifted to the outside and crosswalks moved back, using the existing infrastructure and keeping costs to a minimum. This improved awareness reduces the risk of collision and encourages cycling and walking as safe and enjoyable modes of sustainable transportation.

Morgenstern ResidenceResidential Design - New North Garden CentreSummer 2010



Higgins ResidenceResidential Design - Horlings Garden CentreSummer 2011

The challenge at the Higgins cottage on Stoney Lake was to direct drainage to prevent soil washing away and to create lawn and garden areas. We dug a stream at the outlet of the natural spring and sloped the driveway and yard toward this side of the property We built up the edges with limestone boulders and plantings that included iris, willow, asters, and lilies. After the spring runoff the lower part of the yard was built up to accomodate a fire pit and lawn.

As the designer and project manager at Horlings Garden Centre I met with the clients, drew up a plan, ordered material, scheduled my crew, coordinated with subcontractors, and supervised construction,.
