York Flood Alleviation Scheme
Major milestone for £45 million York Flood Alleviation Scheme
Project Overview
Flood Alleviation Scheme
A major milestone has been reached as construction work gets underway on the Environment Agency’s York Flood Alleviation Scheme, in partnership with City of York Council. Contractors have started preparing to raise and improve flood defences from Westgate Apartments to the Park Inn hotel on North Street. This section of the flood defence scheme will also see the floodgate under Lendal Bridge increased in height. A site compound has started being constructed on Tanner Row opposite the Maltings pub. The work forms part of the £45 million York Flood Alleviation Scheme which will better protect 2,000 properties across the city by 2021.
The work will consist of:
Raising the existing floodwall along North Street by up to 30cm and installing new flood gates, and increasing the width of the gate nearest Lendal Bridge to 2.5m to improve access
Increasing the height of the Lendal Bridge floodgate by 30cm with an additional 15cm demountable panel for extreme events.
Enabling demountable flood barriers to be used across the main and second entrance to the Memorial Gardens.
Constructing a new flood wall up to 70cm high along Leeman Road from Westgate Apartments to a new embankment in the grounds of York City Rowing Club, with the incorporation of demountable barriers at access points.
Raising of the wall and replacement/refurbishment of penstocks at the Park Inn/riverside walkway.
Cllr Andrew Waller, Executive Member for Economy and Strategic Planning, said: “City of York Council is working closely with the Environment Agency on these schemes. Protecting people’s homes and businesses is an absolute priority so we can defend the city in the future”.
Lendal Bridge
The Lendal Bridge floodgate installation is the last stage of the Environment Agency’s work from Ouse Bridge to Scarborough Bridge on the station side, which has included raising defences along North Street Gardens and Memorial Gardens. This section of the flood scheme better protects 39 homes and businesses from flooding, as well as access roads.
Bishopthorpe
The Bishopthorpe work includes the construction of a 180 metre-long flood wall running along Chantry Lane and the boundary of the palace grounds, incorporating a six metre-deep steel barrier underground; a floodgate across the bottom of Chantry Lane and water flow mechanism. This reduces the risk of flooding to 117 properties, as well as Main Street, therefore helping to protect access for residents in the south of the village.
Marygate
Elsewhere in the city, a site compound will be built in Marygate car park from Monday 10 May to facilitate the raising of the flood embankment in the Museum Gardens, as well as increasing the height of the flood walls and gates between Scarborough Bridge and Museum Gardens, including installing glass panels on top of the defences along Earlsborough Terrace. The work will reduce the risk of flooding to 57 homes and businesses in the Marygate area.
Clementhorpe
A site compound was established on the playing field in Rowntree Park last month to enable construction work to take place on the Clementhorpe section of the scheme, between Skeldergate Bridge and Millennium Bridge. Construction on Terry Avenue will include complex underground work, with a 240 metre-long and six metre-deep semi-permeable barrier being installed in order to prevent flood waters seeping through the ground and undermining overground flood defences. This work will require large machinery to be used that requires appropriate safety precautions to be taken. To ensure the safety of the public, a section of Terry Avenue will be closed from Skeldergate Bridge to just before the entrance to Dukes Wharf. The closure date is yet to be confirmed by the Environment Agency’s contractors but is currently expected to start on Monday 17 May and take 12 months. Once completed, the Clementhorpe section of the flood scheme will provide improved flood protection to 135 homes and businesses. The Environment Agency has worked with City of York Council and the community to create suitable diversion routes. The routes were reviewed and approved by an independent road safety auditor, before being submitted to the council for their review and approval.
