APPENDIX 1

GUIDELINES FOR LANDSCAPE REPLACEMENT AREAS WITHIN NEW DEVELOPMENTS NO. PARAMETER DETAILS

1 Definition Landscape Replacement Areas are landscape areas provided on the 1st storey or upper levels of the development and in total minimally equivalent in size to the development site area (see Fig. A). Fig. A. Diagram showing the various types of Landscape

Replacement Areas that could be incorporated within a development

2 Computation Requirements

The computation of the Landscape Replacement Areas will be determined by the horizontal surface area of the landscape areas. To be computed as part of the Landscape Replacement Areas within developments, these landscape areas have to be: a Uncovered and exposed to the sky;

OR

b If covered, to be open sided, naturally ventilated and qualify for GFA exemption under the prevailing development control guidelines for Planter Boxes, Sky Terraces and Communal Landscaped Areas on the 1st Storey;

AND

c Communal and accessible by the public or occupants of the building.

As a guide, at least 40% of the overall required Landscape Replacement Areas should be for permanent planting, ie. softscape.

3 Performance Requirements

The Landscape Replacement Areas are also to meet the following performance requirements: a To be designed to be safe (e.g. to take into consideration

wind / structural loading issues associated with upper storey landscape areas) and easily maintained (e.g. with irrigation and maintenance systems); and,

b To be well designed, lushly landscaped and integrated with the overall form and architectural treatment of the building.

4 Softscape Requirements

The following are requirements for the 40% softscape areas: a As a guide, a minimum soil depth of 1000mm is required for

trees and palms, 500mm for shrubs and climbers and 300mm for ground covers;

b The softscape area will be determined by the horizontal area

of the permanent planting bed; c A combination of trees, palms, shrubs, ground covers and

creepers is highly encouraged; and, d Potted plants will not be counted as part of the softscape area

as they can be easily removed.

5 Planting References

Please refer to the following publications by NParks or PUB for more detailed planting references: a Handbook on Skyrise Greening in Singapore (2002), NParks; b A Selection of Plants for Green Roofs in Singapore 2nd

Edition (2008), NParks; c Trees of our Garden City, 2nd edition (2009), NParks; and d ABC Waters Design Guidelines, PUB.

6 Hardscape Areas

The remaining Landscape Replacement Areas can be designed as hardscape areas, including: a Footpaths; b Seating; c BBQ pits; d Events plazas; e Water features; f Playgrounds; g Recreational facilities e.g. tennis courts and swimming

pools; and h Vehicular drop-offs and drive-ways, provided they are

well designed, paved with appropriate material and integrated with lush landscaping comprising trees and shrubs.

Service facilities such as vehicular ramps and surface car parks will not be computed as part of the required Landscape Replacement Areas.

7 Exemption The building footprints of conserved buildings are exempted from the computation of the development site area required for Landscape Replacement Areas. URA will exercise flexibility on the requirements for Landscape Replacement Areas when evaluating developments with technical constraints, e.g. height constraints, on a case by case basis.

8 Maintenance Building owners are to retain the required Landscape Replacement Areas, which will form part of the common property for strata subdivided developments.

9 Alterations to the required Landscape Replacement Areas

No formal submission is required for changes to the planting species subject to compliance with the softscape requirements. Any changes to the softscape areas (e.g. planting and structure of the planting beds) and hardscape areas resulting in an overall reduction in area for the required Landscape Replacement Areas will require URA’s approval.

APPENDIX 2

SUBMISSION REQUIREMENTS 1 For Provisional Permission / Written Permission

a Development Application submission for Provisional Permission / Written Permission

is to include the submission of a landscape proposal in the form of landscape plans (See Appendix 2-1 for example of a Landscape Plan) indicating the following:

i. Declaration of the overall Landscape Replacement Areas and softscape areas for

the entire development and for each landscape plan

ii. Layout of the softscape and hardscape areas

iii. Schedule of proposed planting species and paving materials

iv. Annotations in the landscape plans to show the proposed planting species and paving materials corresponding to the schedule and the proposed uses e.g. Swimming Pool, BBQ Area etc

v. Sections showing the depth of all the proposed planting beds for Landscape Replacement Areas

vi. Short statement explaining the proposed irrigation and maintenance for the permanent planting

b Please label and package the landscape plans and sections separately from the rest

of the plans; and c Please refer to the DC handbook on Gross Floor Area

(http://www.ura.gov.sg/uol/publications/technical/dc-handbooks.aspx) for the submission requirements to facilitate the evaluation of the GFA exemption for Planter Boxes, Sky Terraces and Communal Landscaped Areas on the 1st Storey and other relevant guidelines.

2 For Clearance of Completed Works

a The Landscape Replacement Areas shall be implemented according to the approved plans and verified and endorsed by URA. URA’s Clearance of the completed Landscape Replacement Areas is required before the Commissioner of Building Control issues the Temporary Occupation Permit (TOP), or Certificate of Statutory Completion (CSC) (when TOP is not required). The building owner is to submit confirmation of the completed works to URA to seek Clearance of the completed Landscape Replacement Areas. The standard processing time to evaluate and approve a complete and compliant submission will require up to 4 weeks. Please note that a longer processing time may be required if the submission is incomplete or not in order. The Applicant is to ensure sufficient lead time is allowed to secure the Clearance prior to applying to the Commissioner of Building Control for TOP/CSC.

b Your submission is required to include accurately labelled photographs (in pdf file

format) showing the completed Landscape Replacement Areas. URA will evaluate

the photographs submitted and, if necessary, arrange for a site inspection before issuing the Clearance for the completed works.

c Applicants are also required to declare upfront to the Commissioner of Building

Control at the point of application for TOP or CSC (when TOP is not required), that URA’s Clearance is required for Landscape Replacement Areas before issuance of TOP, or CSC (when TOP is not required).
