Development Assessment Report - 85 Gympie Street, Tewantin

Proposed Development
Noting Council’s in principle agreement to discharge stormwater to Gympie Street, Lyndsay
Consulting have prepared a Stormwater Plan (Attachment 1), demonstrating the proposed
alternative stormwater arrangement.


Figure 3 below demonstrates the proposed arrangement detailing the proposed arrangement.
Due to site topography that falls from north (front) to south (rear), the proposed infrastructure
requires charged lines. As per the Civil Engineering Plans (Attachment 1) the proposed
arrangement removes the existing 3000lt detention tank and existing outlet pipe that discharges
stormwater to 61-63 Wade Street, Tewantin.


The proposed arrangement contains a slow release pipe and level spreader to ensure captive
stormwater can be released post rain events. As demonstrated in Figure 3 below, the
development will discharge stormwater via two (2) kerb adapters within Gympie Street.
