A proposed multi-use facility will provide more space for sports in Napier.
The City Council has lifted the lid on the findings of its $500,000 business case which will soon be presented to the new council.
As well as housing a velodrome track the proposed facility would go "a long way toward" helping the shortage of indoor court space in the region.
The space would be made "truly multi-use", council chief executive Wayne Jack said, by elevating the velodrome track above court space, which could host basketball, netball, futsal, and volleyball games.
A community health and sports centre, spearheaded by Sir Graeme Avery, is also being developed at the Regional Sports Park.
As well as addressing the doubling of demand in Napier over 12 months, the additional court space would provide room for existing sporting codes to grow - with numbers playing futsal increasing by 34 per cent each year, and basketball growing by 200 per cent during the past five years.
Below spectator seating of between 500 and 750, the court space could transform to hold national, and international size courts for different codes.
Looking at Cambridge's Avantidrome as inspiration, Mr Jack said as well as cycling, and indoor sports, the facility would provide opportunities for those of all age groups, and physical abilities.
There were a number of identified schools, community groups, and sporting codes - from rowing through to rugby- who also felt they could utilise the 250m long wooden cycling track.
Modelled on the velodrome in Darby, England, raising the tier two track would remove issues which arose when the two were on the same level and would provide other opportunities for the space.
Although a wooden framing underneath the track could allow for much-needed storage space, the council had budgeted to instead use concrete. This would allow the space to be used for commercial activities, such as a gym.
As council's engagement with iwi had shown "hubbing" was a popular suggestion, other activities such as a cafe, retail, or physiotherapist area had been touted.
This engagement had been part of the council's $500,000 detailed business case.
Although the process had taken a long time, Giblin Group director Jenni Giblin said they had been able to do it properly, and engage with sporting groups, and key stakeholders.
"I think we've now gotten to an end point where we've designed a facility that is going to meet the needs of the community," she said.
As well as recreational sporting activities, the venue could attract new sporting events to the region, and be a possible venue for concerts, event shows, or conferences.
Its estimated cost was around $20 million, Mr Jack said. As it was now a multi-use facility, more funding opportunities were opened up to council.
They would apply to a number of central funds, as well as going to gaming, and private trusts in Hawke's Bay.
The council would ask for "a small amount" through community fundraising, but this would not be done until the end of the process.
Although some funders had indicated they would contribute, it would not be until the detailed design process was underway they came on board.
"Until you're a certain way down the track, funders won't commit because they don't know if the projects definitely happening," Ms Giblin said, "but certainly, all the conversations we've been having have been really, really, positive."
Mr Dalton gave an "absolute undertaking" that if the project could not be funded council would not do it.
It was estimated the annual upkeep of the facility would be around $180,000 but through its range of uses Mr Jack said the facility would generate $3.6 million of economic benefit annually.
Mr Dalton stressed despite public concern, it was not "an either or situation" between the facility, and a swimming pool.
"If a business case proves there is a need for both, we'll build both, so it's not an either or situation at all," he said.
After being peer-reviewed, the business case would return to council. If approved, the detailed design process would begin.
