The Mayor of London welcomed the £1.5million investment in the lido, but responding to questions tabled by the Friends of Ruislip Lido - who want to encourage public engagement in Hillingdon Council's plans - he said: "Making the lake more attractive to a wider range of users could bring a range of benefits, but it is important that the council properly takes the views of the Friends of the Lido into account."
He said: "I understand that Hillingdon Council is investigating the feasibility of a number of projects at Ruislip Lido with a total investment of £1.5m, including the introduction of boating.
"The lido is a 60-acre lake set within Ruislip Woods nature reserve and is a fantastic recreational resource for the residents of Hillingdon and beyond.
On Tuesday the Friends submitted a petition with 400 signatures, expressing concerns at proposals to allow boating on the lake and to extend the car park.
Vicky Brownlee, chairman of the Friends, said: "We are trying to gain support around the plans. It is not that we are against everything but we want to have a voice."
Commenting on the Lido, council leader Ray Puddifoot said: "Ruislip Lido is a great asset for the people of Hillingdon and we are committed to enhancing and improving the facilities there, taking on board the views of residents across Hillingdon once detailed proposals are available."
