The contract, which will run from 1 January 2017 to 31 March 2027, extends ISS' 23-year relationship with Arun District Council.
But the new agreement is "no ordinary grounds maintenance contract", according to ISS Facility Services Landscaping managing director Phil Jones. The new approach will see ISS investing in green spaces and offer training opportunities for locals.
It will include upkeep of parks, cemeteries and outdoor recreation facilities, along with repairs and maintenance to more than 70 play areas. It also includes the supply of plants for the many bedding displays throughout the district.
Arun put the contract out to tender last November with an expected value of £12m - £15m. Four tenders were submitted in total, with ISS coming out as the highest scoring bidder from the tender process.
The company has also pledged to invest more than £650,000 on improving green spaces, including creating an adventure golf facility at Hotham Park, Bognor Regis, bringing a free public challenge fitness course to East Beach Green, Littlehampton, and investing in Norfolk Gardens in Littlehampton.
In partnership with Arun District Council, ISS will also renovate the cafe at Marine Park Gardens in Bognor Regis and has pledged to provide free-to-use tennis courts.
The award of the contract was approved by members of Arun District Council's Cabinet at a meeting earlier this month. The delivery of the contract fits with the Council's Priority of "Your services - delivering you the best services we can afford" and the 2020 Vision programme – to reduce costs, make service improvements and balance the budget.
ISS and Arun District Council will be consulting with interested parties to help shape the planned improvements.
Councillor Terence Chapman, Arun District Council's cabinet member for environmental services, said: "We are proud of our 240ha of parks and open spaces in Arun and I am very pleased that ISS Facility Services Landscaping has been awarded this innovative new contract. I am confident that they will deliver a high-quality service and, working closely with the Council, help it to deliver its priorities."
Managing director Phil Jones: "I am delighted that ISS has been awarded the next generation green space management contract with Arun District Council. All tenderers were set the challenge of rising to meet the future requirements of Arun residents and visitors to the district. This is no ordinary grounds maintenance contract, nor should it be, given the uniqueness of the Arun district.
"I am glad my team has risen to the challenge of providing a cost effective, value for money service, whilst also committing to significant investment for the future, which will deliver some exciting projects, as well as providing a number of employment opportunities for local people. I look forward to delivering those commitments and to working in partnership with Arun District Council for the benefit of all stakeholders."
As part of the new contract, ISS will offer three apprenticeships and a placement for a marketing graduate. Currently, 94 per cent of its Arun workforce is from the local area.
ISS has pledged to give 200 hours of free voluntary support to Arun's network of community groups along with making a £2,000 grant funding pot available to them, and invest £875,000 in new machinery and equipment.
