URBAN FOREST STRATEGY Planting within Drainage Reserves TA4 Sumps - - PowerPoint PPT Presentation

URBAN FOREST STRATEGY Planting within Drainage Reserves

TA3

• 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

Sumps

TA4

• There are a lot of constraints with beautifying
• ur 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

Sumps

TA5

So what are we left with? Sumps

TA6

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”

Sumps

TA7

• 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

More Trees in Sumps?

TA8

To identify where we can plant we first identify were we can’t plant. More Trees in Sumps?

TA9

Can’t Plant Here?

• By default we can’t

plant into the wet area

• f the site – the

sump/basin

TA10

Can’t Plant Here?

• The fence line needs

to be maintained so that future canopy does not come into conflict with the neighbouring property

TA11

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

TA12

Can’t Plant Here?

• Plus other constraints

need to be considered for the management of the tree

– Power lines – Lighting – Access to drainage infrastructure

TA13

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

Now we can plant?

GRAPHICAL REPRESENTATION

TA17

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

We gain canopy

• Selby Park and Sump at Greenshields

Way

– 13 trees providing an estimated 1,021 m2 when mature

• Severin Walk Planting in Winter 2015

– 11 trees providing an estimated 864 m2 when mature

TA20

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)

TA21

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

TA22

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
