Trinity Valley Upgrade overview
The Trinity Valley Drainage Upgrade involves the installation of new stormwater drainage infrastructure in the suburbs of St Morris, Trinity Gardens, Maylands, and Stepney (known collectively as the ‘Trinity Valley’) undertaken in four stages.
The Project is designed to:
- reduce the risk of flooding and damage to local properties
- increase capacity of stormwater drainage infrastructure for 1-in-100-year storm events, and
- use Council reserves and streets for temporary stormwater detention.
Stage 4
Stage 4 includes the contruction of a detention basin within St Morris Reserve, and the installation of new culverts, pipes and pits within the roadway.
The streets included in the Stage 4 works are:
- Glynburn Road (near intersection of Third Avenue)
- Third Avenue (from Glynburn Road to Gardiner Avenue)
- Green Street (from Third Avenue to Seventh Avenue
- Seventh Avenue (from Green Street to Gage Street)
- Gage Street (from Seventh Avenue to Gwynne Street).
The roadways in Green Street and Seventh Avenue will be resealed as part of the works. Trench and road reinstatement only will occur on Glynburn Road, Third Avenue and Gage Street.
St Morris Reserve
St Morris Reserve will be upgraded in association with the construction of the detention basin. The Reserve upgrade is planned to include new:
- playground equipment and shade sails
- park furniture
- picnic shelter
- toilets
- hard surfacing (paths, basketball court), and
- irrigation and landscaping (trees, shrubs and lawn).

Funding
Stage 4 and a major portion of the St Morris Reserve Upgrade will be funded as part of the Council’s $20m Trinity Valley Stormwater Upgrade Project.
The Federal Government is contributing $9.9 million as part of its Preparing Australian Communities Program, which targets projects that improve resilience against natural disasters. The investment is being matched dollar by dollar by the Council, resulting in a near $20 million investment to reduce the risk of flooding.
