Further consultation needed over new watersports centre
Daniel Clark
Local Democracy Reporting Service
Further consultation will take place to identify the best place for a watersports centre in Teignmouth after a decision over its location was deferred by councillors.
A report to Teignbridge District Council's executive committee identified the Lower Point Car Park as the preferred site for a watersports centre for the Rowing, Beach Surf Life Savers and Canoe Clubs.
But the committee heard the Beach Surf Life Savers had already pulled out of any proposed move, while serious concerns about the lack of any wider consultation were raised.
The watersports centre would be part of the major regeneration proposals for Brunswick Street, where the rowing club is already a tenant.

Extra costs to The Box due to 'unforeseen problems'

Local Democracy Reporting Service
Major unforeseen problems have added to the construction cost of Plymouth's new history and culture centre The Box, councillors have been told.
They have been given a run down of some of the biggest setbacks which have had to be overcome by the building team turning the former museum, library and St Luke's Church on North Hill into the new centre.
Plymouth City CouncilCopyright: Plymouth City Council
Councillors were also told the cost of setting up the 11 exhibitions and five other displays areas is set to rise by an extra £2.5m from the budgeted £3.7m, pushing the total cost above £40m.
The final total is expected to be reported to the city council's cabinet in October.
The problems found were:
Several of the supports for the first floor balcony had no foundations and the rest were on timber wedges
A Victorian culvert turned out to be a surface water drain which was not properly connected to the drainage system, so a large section of sewer had to be replaced
When work was being carried out on the former library, builders discovered a large basement filled with wartime rubble
The whole side of the building had to be supported with sheet piling to hold it up as a result

A "cowardly" attacker has been sentenced to eight years in prison for two
different unprovoked attacks on friends who were left with serious facial
injuries.
Sam
Trendell, 23, was caught on CCTV during the more serious assault in a car park in
Newton Abbot in which he repeatedly punched and stamped on the victim
as he lay on the ground.
Devon and Cornwall PoliceCopyright: Devon and Cornwall Police
The attack, which happened in April, carried on for 77 seconds, and at one point Trendell picked up unconscious victim Jack Knight, threw him back down so he was lying face up, and went on to punch his face at least six times.
Mr Knight suffered two fractures to his left eye socket, a broken jaw and nose, and spent two days in intensive care and eight days in Derriford Hospital, Plymouth.
Trendell, from Windsor Avenue, Newton Abbot, also attacked Nathan Meek nine months earlier, leaving him with a broken jaw which had to be fixed with a plate.
Sentencing him at Exeter Crown Court, Judge Paul Cook said: "You carried on attacking Mr Knight when he was no more than a sack of potatoes and completely motionless."

Cornwall growers 'puzzled' by EU-worker pilot scheme
Neil Gallacher, Business & Industry Correspondent
BBC Spotlight
A government pilot scheme to let non-EU migrant workers come to Britain to pick fruit and flowers has left some Cornwall-based growers puzzled.
UK growers will be able to recruit non-EU migrants as seasonal workers after Brexit under the new pilot scheme. It will run between spring 2019 and December 2020. The visas for up to 2,500 workers a year will last for six months.
Flower grower James Hosking of Fentongollan Farm said: "It looks like a very, very modest move. We alone need 60-70 people on our farm. So our needs would in theory take up about 3% of the national total."

Jeremy Best of Mitchell Fruit Garden said: "It looks like a sop. We need 95,000 seasonal workers nationally, not 2,500. We need more information but I suspect it's nothing more than appeasement that they're offering here."
The NFU nationally however described it as is "a major victory for the NFU, its members and the public".
A Defra spokesman told the BBC on Thursday morning that the question of why only 2,500 workers are included - and why only Non-European Union nationals at that - was an immigration matter, and therefore a question for the Home Office. So far the Home Office has not responded.
Inquiries are currently underway to find and inform the next of kin.
