John Robinson has estimated the overall cost of the proposal to revitalise the area between the Wimmera River and Baillie Street in Horsham to exceed $100 million.

But chief executive Sunil Bhalla says it is too early to put an overall price tag on the plans.

The draft Horsham Wimmera River Precinct and Central Activities District Vision and Masterplan is on public exhibition until August 30. It includes plans to give Horsham's riverfront a facelift, redevelop Horsham City Oval and add a new multi-purpose sports stadium to McBryde Street, among other changes.

Cr Robinson's estimates include $40 million to realign Horsham City Oval and relocation costs of $10 million for Wilson Bolton Holden, $6 million for Horsham Lawn Tennis Club and Horsham Croquet Club, and $1 million for the Sawyer Park Steam and Model Engineering Club.

He said this would mean ratepayers would have to find up to $5 million a year, across 20 years, along with interests and operating costs.

"It would mean a rate hike of 25 per cent per annum if we cannot attract funding elsewhere - like government grants," he said.

"It could also be business investment - I'm not sure where we could get that - but even if the government put in 50 per cent per project on average, you're still looking at 12.5 per cent per annum (rate rise) averaged over 20 years."

Cr Robinson said he was concerned no cost estimates had been provided, and that the plan disregarded aspects of the 2019-23 council plan - which includes a clause to investigate alternatives for the multi-purpose sports stadium.

"What's going to happen is the community is going to comment on these plans with no dollars in the consideration whatsoever," he said.

Cr Robinson said he used council documents such as the Wimmera Sports Stadium business case and concept design report from December 2017 to reach his estimate, and had also consulted with businesses affected to gauge the likely cost to them.

One of those impacted, Jill Taylor, lives with partner Ross Brown on McLachlan Street. Ms Taylor's property is not included in the draft plan, with "new government buildings" and an "open space" instead occupying the area.

She agreed with Cr Robinson's estimate it would cost the community about $1 million for her and Dr Brown to be displaced. Dr Brown runs his own chiropractic business from the premises.

"We don't know where this business is going to go. At the moment, Ross is the only person who works there - but we have spoken about expanding it," Ms Taylor said.

"I'm seeing that the mayor and the chief executive are saying everyone's been contacted, but I haven't."

Horsham Greyhound Racing Club president Justin Brilliant said the club was still completing its submission to the council.

He said Cr Robinson's estimate that relocation costs could reach $20 million was "not unreasonable".

"We're not 100 per cent certain on costings, but we're not stopping investment at the site," he said. "We have $1 million plans to build shade sails over the carpark."

Horsham Football Netball Club president Geoff Lord said the club was "committed to direct communication" with the council regarding the cost of upgrades to Horsham City Oval.

Sunil Bhalla said the council did not have estimates for the cost of works, but cast doubts over the idea rates could rise to pay for the projects.

"Once council has endorsed the master plan, we will look at the detailed costings," he said.

"We can't increase the rate cap beyond what the office of local government allow us. There is the opportunity to apply for rate variations, but my understanding is there is no appetite from this council to seek that."

Mr Bhalla said the council was still following its 2019-23 plan by exhibiting a master plan including the stadium.

He said there would be more opportunities for engagement with stakeholders once the master plan was adopted, and that council had received more than 400 submissions since the engagement period commenced in early July.

The federal government in May committed $1.65 million to the master plan.

"That is in line with the funding we had been seeking," Mr Bhalla said.

Member for Mallee Anne Webster said a deed of agreement between the government and the council for the money was in process this week.

Editorial: City futures planning is everybody's business

I WRITE regarding the current Wimmera River and Central Activities District planning process being undertaken by our council.

Community concerns that have not, or are not being addressed include:

To assist, I provide the following:

Quantifiable costs in the plans exceed $100 million which means that ratepayers may have to find up to $5 million per year over 20 years, plus interest and operating costs - less any government grants. This is a rate hike of up to 25 per cent per annum if we cannot attract other funding.

To assist in the process, I have made inquiries of some of parties impacted by the council plans to gauge what might be a likely community cost. Anonymity is provided to minimise business impact.

The Horsham City Oval realignment and replacement of buildings and land aquisition would cost $40m on the planned alignment; the multi-user sports stadium $25m and Horsham Greyhound Track relocation $20m, both with operating expenses excluded; major business A $10m and major business B $1m; Horsham Lawn Tennis courts and croquet club $6m; and the miniature railway $1m.

Twenty years of no growth may well be a death sentence to a club or group, is certainly not good for impacted businesses and clearly detrimental to employment.

Parallel parking in the CBD is perceived as being detrimental to business. The failure to resolve heavy vehicle congestion in the CBD and the disappearance of McBryde Street are perceived to be unproductive and unsafe.

It is not acceptable that the community are asked to make decisions without being fully informed.

John Robinson, councillor, Horsham Rural City
