1. Introduction
Enrich Architecture has engaged STP Consultants to produce a Development Assessment Report for Engineering
Services, in support of an application for Material Change of Use over the site for an extension to an existing Aged
Care Facility.
This report will provide additional detail in the following areas:
Site earthworks
Stormwater drainage and flooding
Stormwater quality
Water supply
Sewerage reticulation
Preliminary traffic impact
2. Site Description
The site is located at 100 Cooyar Street, Noosa Heads and described as Lot 9 on RP225312 with a land area of
2.5ha. The site is zoned Community Facilities under the Noosa Shire Council City Plan and is currently used as an
Aged Care Facility.
Figure 2.1 – Zoning and Locality Plan (NSC Mapping)
2.1 EASEMENTS
There is a single access easement A on SP197575, for an electrical sub-station, as shown in Figure 2.1 below.

2.2 PROPOSED DEVELOPMENT
The proposed development consists of demolition and reconstruction of accommodation wings, administration
building, and a community centre as depicted in Figure 2.3 below.

3. Stormwater Management Plan
3.1 FLOOD STUDIES
According to the Noosa Shire Council Flood Study, the site is not subject to flood inundation at the AEP 1% level.
3.2 STORMWATER DETENTION
Comparison of the impervious areas between the existing layout and the ultimate layout following Stage 3B, shows
no increase. As there is no change to the impervious area, there is no change to the overall site runoff. As this is
the case, there will be no requirement for on-site detention.
3.3 STORMWATER QUALITY
Although the site area is greater than 2,500m2, the proposed development does not result in a change to the net
developed area. Also, the area of disturbance will be less than 2,500m2. In accordance with the requirements of
the State Planning Policy, stormwater quality treatment will not be required.
3.4 SITE STORMWATER DRAINAGE
A preliminary stormwater drainage layout is illustrated in Figure 3.3. The roofs and paved areas are to discharge
or connect directly to the existing internal stormwater infrastructure via roof water and grated inlet pits then
connect to the open drainage structures that currently discharge to the eastern boundary.
The existing access track that is positioned downstream of the stormwater outlet is in disrepair and subject to
washouts during severe rain events. A rock-lined causeway is proposed to ensure trafficability during rain events.
Detailed design drawings are included in Appendix B to this report.
3.5 EXISTING STORMWATER INFRASTRUCTURE
The site currently drains to the wetlands to the north-east, which is the Lawful Point of Discharge as illustrated in
Figures 3.1 and 3.2 below.

3.6 SITE EARTHWORKS
Existing site levels and grades are to be maintained. A minimal volume of fill may be required for building pad
works.
4. Water Supply and Sewerage
4.1 WATER CONNECTION
The new buildings will connect into the existing internal reticulation as illustrated in Figures 3.1 and 3.2 above. All
new and amended fixtures will be subject to a Plumbing and Drainage Application to Noosa Shire Council. It is
unlikely that the existing connection to the Unitywater infrastructure will require upgrading. This is located to the
north of the main entrance in Cooyar Road and fed by a crossing from the 150mm main located on the opposite
side.
4.2 SEWER CONNECTION
The new buildings will connect into the existing internal reticulation as illustrated in Figures 3.1 and 3.2 above. All
new and amended fixtures will be subject to a Plumbing and Drainage Application to Noosa Shire Council. It is
unlikely that the existing connection to the Unitywater infrastructure will require upgrading.
As illustrated in Figure 4.1, the site is traversed by existing Unitywater sewer infrastructure. Any construction within
5m of this 300mm trunk main will require approval from Unitywater under Queensland Development Code MP1.4.

5. Roadworks and Traffic Impact
5.1 PARKING AND ACCESS
The parking and access will remain mostly unchanged in this development. As the development will not generate
additional traffic and no new vehicle access, parking or manoeuvring areas are proposed, there will be no impact
to the existing road network.
Turning paths for the proposed refuse area and the delivery/service area are shown below. As illustrated, an HRV
can manoeuvre through the service area utilising a three-point on entry and a single movement to exit. If parking
bay #57 is removed, then the HRV can enter and exit in a single movement. In order for the garbage collection
vehicle to access and exit the refuse area in one movement, the entrance will need to be widened by 2.5m from its
current width.

6. Conclusions
The proposed development is in complete compliance with Development Codes 9.3.4 Special Residential Code
and 9.4 Works Code.
