Why green the site?
Members of the Portsmouth Society and a City Council officer met on the site in April 2011 and agreed why we want to green this site. As a main road entry point to the city centre, the bare expanse of carpark does not give the impression of a vibrant, innovative, well designed approach for visitors to the Historic Dockyard, shoppers, university students' parents... not to mention how it feels to Portsmouth residents.
There is currently a gap on the south side of Market Way in the 'green corridor' which otherwise extends on the north side from the new landscaping in Mile End by the Highways Agency to St. Agatha's park. Facing the Tricorn site are eight plane trees and bushes bordering the Pitt Street carpark, maintained by the city council. Ivies are growing well in the central barrier of the road.
Portsmouth as a city is seriously lacking in greenspace. This proposal which would bring visual benefit - a green link - to a grey, desertlike area. Designed by Architect Carl Leroy-Smith, this would also be the first temporary greening of a recession-hit site in the south of England.
How will it be done, and who will be involved?
The proposal is to green the elongated triangular site bordering Market Way and the Cascades approach which is not used for carparking - shown on the attached maps kindly supplied by David Moorman. To launch the greening, special arts events related to the site’s history will be screened.
As the Northern Quarter development which has planning permission is not going ahead, the proposal is for a timescale of five years, rather than one-off events such as Greening the Grey in Islington, although these and activities with local artists and gardeners would not be ruled out for later phases.
David Moorman would negotiate with NCP which has the lease of the site from the City Council, on the basis of this proposal which has input from those who support the bid. Images are needed as examples of temporary greening in other areas.
How will the site be used?
Although there are 875 people on the waiting list for allotments it was regretfully agreed that the site was not suitable for growing food, because of lead pollution from traffic and there are no 'eyes on the street'. We propose trees, shrubs and plants in low cost planters - maybe sewer pipes or builders' bulk bags, initially positioned on the tarmac surface at the curve of the Cascades Approach road at the back of St. Agatha’s, which is prominent in the view from vehicles entering the city.
Drought resistant plants adapted to growing in containers would be selected, and provision in the bid would be costed for maintenance and watering from bowsers (DM). An approach to the Naval Base Property Trust was being made for a boat/boats as planters (PP).
Who will be asked to Sponsor the greening?
Colas (PP, DM) - which pays £3000 towards Portsmouth in Bloom
The Tree Council and Woodland Trust to sponsor trees.
B & Q - which has a community arm,
Portsmouth Naval Base Property Trust - "Welcome to Maritime Portsmouth"’
Argos, Cascades Centre Management, Marks & Spencer, Body Shop and other retailers in the Cascades
Supporters - help with design, planting and maintenance and special events:
Ward councillors, Councillors Lee Hunt and Michael Andrews
Kathy Wadsworth, Strategic Director, Steve Baily Head of Culture Portsmouth City Council
Contributions from community funds to the bid.
Stephen Rees, Community Horticultural Officer and Stuart Campbell PCC Arboriculturalist for advice - on species and implementation (DM).

Phase 3 2013
Greening the wider Northern Quarter eg Pitt Street Baths site, ABC cinema should be considered since nothing is likely to be built on these either for a long time.
Hedges might help to keep the traffic pollution out. Advice is being sought from The Federation of City Farms and Community Gardens
