A shortage of sports fields in The Hills could be water under the bridge if a current Sydney Water Landscape Masterplan is approved.
The plan for Sydney Water-owned land bordered by Windsor Road, Sanctuary Drive and the North West Rail Link includes the construction of three playing fields and a baseball diamond.
Cycleways and footpaths would also be built along Caddies Creek and Strangers Creek at Beaumont Hills.
The plan was developed in collaboration with The Hills Shire Council, Transport for NSW and the NSW Department of Planning and Infrastructure.
The Hills mayor Michelle Byrne said council wished to help local sporting clubs and associations grow.
"We don't have enough sporting fields in the Hills [and] this presents a number of opportunities not only for playing fields but for more open space for our residents, who will have some fantastic park land nearby," she said.
Hawkesbury MP Ray Williams was approached by residents concerned at a trunk drainage fee they were being charge for the under-utilised land.
He wrote a thesis on the Balmoral land release which included the proposed park site while completing his masters degree in planning, so was very familiar with the area.
"People started getting charges last year that were the equivalent of $1000 extra a year on their water rates over five years," he said.
"This plan was in direct response to that cost, and is a more efficient use of space."
The program led for land and waterways at Sydney Water, Daniel Cunningham, said the plan also was to protect properties from flooding.
The plan is on public display until Friday, February 28 at The Hills Shire Council, 3 Columbia Court, Norwest Business Park. Details: sydneywatertalk.com.au, 0428 844 768.
