Within Development Site
(only applicable if the development is within
the gazetted Tree Conservation Area or on
vacant land)

Existing trees / single stem palms within the
development boundary and up to 5m from
the boundary
a) species
b) girth – measured 0.5m from the ground
c) height (if available)
d) all trees / single stem palms should be
uniquely numbered and consistent
throughout the project

as follow:
Status of existing trees Outlined in color
/ palms
a. to be retained green
b. to be removed yellow
c. removed without red
written approval
d. removed with
written approval *yellow
*yellow – indicate the approved date in the
tree schedule

4 Proposed Open Space
4.1 Area of open space
The area of open space is computed based
on the formula stipulated by URA
4.2 Location
4.2.1 The walking distance from the furthest
unit to the proposed open space
measured along the road centre, is not
more than 250m
4.2.2 The proposed open space does not
abut a major road and/or park
connector that is abutting a major
road
4.2.3 The open space does not abut an
existing/proposed retaining wall.
4.2.4 The opens space is located such that
at least 2 sides face the front of a
house(s), and none face the rear of a
house(s).
4.2.5 If the proposed development is
adjacent to a proposed or existing
Park Connector,
a. The open space is to abut the
Park Connector provided the
Park Connector is not abutting a
major road and it complies with
clause 4.2.1.
4.3 Accessibility
4.3.1 At least one of the boundaries of the
open space abuts an existing minor
road or a new local access road
4.3.2 Proposed entrance or access path
to the open space is at least 4.0m
wide
4.3.2 The open space is of a regular
shape with a width of at least 30m
4.4 Terrain of the open space
4.4.1 The open space should generally be
flat (gradient 1: 40). If site situation
does not permit the proposed slope
should not be steeper than 1:2.5 and
appropriate measures for slope
stability should be carried out.
4.4.2 The gradient of all proposed slopes
are shown
