Dear Mark and Diogo,

Re: Minor Change to Operational Works Approval - OPW 20/0145 for Reconfiguration of Lot for “Noosa
Business Centre” (NBC) at 28 Eenie Creek Road, Noosaville (Lot 3 on SP246584)

Further to Stockwell’s letter dated 4 November 2021 as part of OPW 20/0145.03 requesting the Lot 3 and Line 5
elements from that Minor Change Application be removed and be assessed separately, we have now revised our
documentation to facilitate a change to our Operational Works Approval, OPW20/0145.04. This change
incorporates: amended stormwater infrastructure at Lot 3 and Line 5 to ensure drainage outlets are not submerged.

The amended infrastructure design incorporates the design methodology reviewed at our site meeting with Mark
Lewis and Diogo Carrico on Tuesday 14 December 2021. This change incorporates:

Amended Stormwater Infrastructure

    1. Lot 3 Outlet Swale

        As currently designed and approved (1856 SW29-E), the Lot 3 drainage outlet is entirely submerged and
        contemplates chasing the outlet to daylight at RL 2.8 within Covenant J.

        We have amended our plans so that the Lot 3 drainage has been connected into the Line 5 drainage via a
        new pipeline adjacent lot 4, thereby eliminating the additional outlet into the drainage reserve.

    2. Line 5 Outlet Swale

        As currently designed and approved (1856 SW28-F), the Line 5 drainage outlet is partially submerged and
        contemplates chasing the outlet to daylight at RL 2.5 within existing drainage channel.

        We have amended our plans to show the Line 5 outlet relocated to the south, at a location where the outlet
        level (RL2.5m AHD) can be achieved with minimal works within the drainage reserve.

To facilitate the above Stormwater Infrastructure Amendments, an interim solution utilising the currently constructed
stormwater network has been proposed to enable the balance of the project to be completed.

Please do not hesitate to contract myself directly on 0410 398 363 or via email to discuss this further and resolve
any matters in a timely manner.

Yours Faithfully,


Steven Wright
Stockwell Development Group
