Kidron Construction

Structural Design

Design Engineering(as “Wilkie”) was approached by Kidron Construction to provide stormwater drainage services for one of their residential properties in Byford.

The primary objective was to provide their expertise in a storm water management plan to demonstrate the adequate draining of the developed subject lands by means of implementing structural controls for the management of storm water runoff.

The storm water management plan had to be approved by local government authority, i.e the Shire of Serpentine-Jarrahdale, as a deliverable in achieving the drainage requirements for subdivision.

Project Brief

Outcome

Prepare Stormwater Drainage Management Strategy

Background

Design Engineering was approached by Kidron Construction to prepare a Stormwater Management Plan prior to subdivision. The purpose of the plan was to fulfil the drainage requirements for subdivision of the subject land into 5 lots as per the conditional approval for the freehold subdivision plan.

Project Objectives

The primary objective was to produce a storm water management plan to demonstrate the adequate draining of the developed subject land by means of implementing structural controls for the management of storm water runoff.

The storm water management plan had to be approved by the local government authority, i.e. the Shire of Serpentine-Jarrahdale, as a deliverable in achieving the drainage requirements for subdivision: “Stormwater is contained on-site, or appropriately treated and connected
to the local drainage system.” – W APC Condition 7. (c)

Challenges

The main challenge was to produce a cost effective strategy which could be easily implemented by the local developer.

Our Approach

Firstly, Design undertook desktop searches and site inspections and made enquiries with the Shire of Serpentine-Jarrahdale, and determined that most of the stormwater runoff in this area is conveyed overland via the road network.

Secondly, Design determined the predevelopment and post development flows from the proposed subdivision. From this information, Design determined that surface water could be retained on site.

Thereafter, Design produced a stormwater management plan and associated drawings and submitted them to the local shire council.
