The policy is to guide the provision of artificial shade over playgrounds in the City.
It comes after the City received a petition in May 2014 to erect shade sails over a playground at Mawson Park in Hillarys.
�The City has maintained a preference for natural shade over built shade structures and has been proactive in providing natural shade (tree planting) to existing playgrounds since 2010,� a council document said.
The policy will only consider artificial shade for parks with high patronage, conditions where trees are difficult to establish and where playgrounds are too large to shade with trees.
A shortlist of parks was presented to the council in October 2014 and the three that met the criteria were Burns Beach Park ($45,000-$50,000), Delamere Park in Currambine ($100,000-$120,000) and the southern playground at Tom Simpson Park in Mullaloo ($40,000-$45,000).
Mawson Park did not meet the criteria because the playground could be relocated under existing natural shade.
�The installation of built shade structures on the parks as listed is a substantial financial commitment for the City and no additional parks are recommended for listing in the near future,� the document said.
The City has received about 70 requests for shade sails on various parks over the past three years.
The City has built shade structures over 19 of its 231 playgrounds, four at parks (northern playground at Tom Simpson Park, Harbour View Park in Hillarys, Blackall Park in Greenwood and McIntyre Park in Burns Beach) and the rest at community facilities such as kindergartens.
There is no budget allocation in the draft five-year capital works program for the installation of artificial shade structures.
