They also hoped that the move would encourage more recycling - as part of an aim for residents to recycle half their waste by 2020.
Council overspend on housing predicted
Local Democracy Reporter
The cost to Worthing Borough Council of placing people in emergency or temporary accommodation is expected to be £274,000 more than planned, while for Adur District Council the overspend is likely to be £54,000.
The figures for the 2018-19 financial year were discussed at a joint strategic committee meeting in Worthing.
Members were told that the increased spending reflected a rising demand coupled with a lack of affordable housing.
The committee's budget monitoring report for the first quarter stated: "Across the South East there is competing demand between local authorities for both emergency and temporary accommodation, the latter often being leased private sector accommodation.
"Whilst Adur and Worthing have made significant progress in leasing more affordable units of temporary accommodation, competition does mean that prices in some areas are being pushed beyond the reach of the councils, and the supply of suitable emergency and temporary accommodation within the borough is reduced.
"The councils are still faced with placing some clients in costly budget accommodation hotel chains when no other suitable options are available."
Elsewhere in the budget, the money made from parking in Worthing was £50,000 higher than expected, thanks to an increase in charges at the multi-storey car parks in High Street, Grafton, and Buckingham Road.
The meeting was told that "excess income" would be used to improve car parks "in future years".
With central government slashing the funding to local authorities, Worthing and Adur, like councils up and down the country, have had to take a long look at how their services are funded.
The meeting was told that Adur had committed to saving £1.365m on its 2018-19 budget, while the figure for Worthing was £1.981m.
As things stand, Adur looks set to overspend by £23,000, while Worthing will underspend by £189,000.
