The funding is aimed at boosting the economy and is comprised of £50m from the Outer London Fund, £70m from the Regeneration fund and £57m from other private and public sector partners.
Johnson announced the 18 boroughs and 23 schemes that would receive funding from the Outer London Fund (OLF), including Green Lanes in Haringey, Bromley town centre and Harrow town centre.
Haringey will receive over £2m to redevelop the southern entry to the high street and to improve shop fronts by carrying out conservation work and by the installation of 14 micro squares on street corners. A further £5m will be spent on the regeneration of Bromley town centre to improve shop frontages and to help independent businesses through support and training.
The OLF has also committed nearly £3m of funding to Harrow town centre to develop a new town park with a permanent multi-use performance space. The funding is also intended to support improvements to town centre access and to fund business support measures including an empty shops initiative and the creation of a Business Improvement District.
The OLF was set up to help regenerate town centres and high streets. Last year nearly £10m of funding supported regeneration across 20 London boroughs.
Johnson also announced that eight boroughs will benefit from a £70m Regeneration Fund which was set up to help repair the damage caused to high streets and town centres during last summer's riots.
Johnson announced that Croydon, Haringey, Camden, Ealing, Enfield, Hackney, Merton and Southwark would all benefit from the fund. Further discussions to bring forward regeneration plans in other boroughs are also taking place, the Greater London Authority said.
"I am in no doubt that London will emerge strongly from the economic downturn but we must keep investing in our many high streets and town centres to address the historic neglect of these areas by others. Kick starting local growth is exactly what these Funds are designed to do,” said Johnson.
Funding agreements are expected to be signed in April and the projects are expected to be completed by March 2014.
