TA3 URBAN FOREST STRATEGY Planting within Drainage Reserves
TA4 Sumps • To date we have successfully beautified some of our sumps where room is available and an integration with public open space (park land and natural areas) – Tomato Lake – Centenary Park Lake – Willow Park Lake – Smythe Lake – Norlin Park – Noble Park
TA5 Sumps • There are a lot of constraints with beautifying our residential sized sumps and sumps in some commercial areas – The large sites with enough room for planting are managed by the Water Corporation – Those which belong to the City are generally small offering limited space • Minimal space within the lot – drainage purposes – Sites are not irrigated and not easily accessible if we were to maintain low native planting – sites are currently grassed and mowed
TA6 Sumps So what are we left with?
TA7 Sumps We can plant trees around the sumps to create more canopy and improve the aesthetics. And this will assist our Urban Forest Strategy initial target! “to replace lost canopy to a coverage which meets and exceeds that of the baseline year of 2001”
TA8 More Trees in Sumps? • Sumps are not the easiest sites to work with – Drainage function will take precedence – Maintenance for drainage function will take precedence - access needs to be maintained – People don’t like “blind spots” in these sites • Passive surveillance needs to be retained
TA9 More Trees in Sumps? To identify where we can plant we first identify were we can’t plant.
TA10 Can’t Plant Here? • By default we can’t plant into the wet area of the site – the sump/basin
TA11 Can’t Plant Here? • The fence line needs to be maintained so that future canopy does not come into conflict with the neighbouring property
TA12 Can’t Plant Here? • Our Crime Prevention section recommends a minimum 2.5m gap between the canopy and the ground to assist with retaining sightlines
TA13 Can’t Plant Here? • Plus other constraints need to be considered for the management of the tree – Power lines – Lighting – Access to drainage infrastructure
TA14 Plan for room? • If we want the best canopy we need to plan for the future size of the canopy and provide room for that canopy • In order to do this the City’s Arborist will choose the best species of tree for each site • Neighbouring residents will be consulted prior to planting
TA15 Now we can plant?
TA16 Now we can plant?
TA17 Now we can plant? GRAPHICAL REPRESENTATION
TA18 How many trees? • We have identified 9 sites • We plan on planting 46 trees • And we gain an estimated 3,611 m2 canopy at maturity
TA19 Canopy Cover 3 trees 4 trees 3 trees 2 trees 4 trees 3 trees 3 trees 1,440 m2 1,126 m2 629 m2 482 m2 447 m2 394 m2 388 m2 390 m2 339 m2 314 m2 314 m2 290 m2 247 m2 236 m2 236 m2 236 m2 236 m2 157 m2 154 m2 104 m2 74 m2 52 Armadale Road 4 Ritchie Way 23 Trink Street 9 Pratt Street 63 Gardiner Street 15 O'Neile Parade 21 Toorak Road Current Tree Area Proposed Tree Area Estimated New Tree Area
TA20 We gain canopy • Selby Park and Sump at Greenshields Way – 13 trees providing an estimated 1,021 m 2 when mature • Severin Walk Planting in Winter 2015 – 11 trees providing an estimated 864 m 2 when mature
TA21 Current Work • Leadership and Governance – Presentation to the Landscape Industries Association (WA) and Nursery & Garden Industry (WA) joint State Conference – Article for Parks Leisure Australia on our Urban Forest Strategy – Internal UFS Working group meetings – Signatory to the 202020 Vision (20% more green space by 2020)
TA22 Current Work • Asset Retention and Management – 100 street trees ordered for winter planting • Awareness, Participation and Capacity Building – ‘Our Trees’ logo developed – Infograph being developed by Marketforce – Dedicated Belmont Connect page
TA23 New Opportunities • Research, Best Practice and Adaptive Management – Inventory of street trees (life expectancy, health, species etc.) – in progress – Canopy coverage via multispectral aerial imagery (% cover, height, vigour) – investigating – Summer Thermal Imagery – mapping the urban heat island effect - investigating
