I will add to this as my ideas expand.
acquiring land
i would ask local councils if they are any council owned land that could be converted into a community project. with preference land with an established tree ie sweet chestnut or walnut tree. land could be from excess urban land/disused carparks to village greens. for urban sites a clean source of water.
local business sponsorships
ask local business for help in making and maintaining the community orchard park.
this could be from asking to borrow heavy machinery to initially build pathways and landscape the area, to discounts for tools, tree stakes, composts and other consumables.
asking local landscape companies to maybe provide free/discounted services such as mowing and strimming but all manual work to hopefully be carried out by community groups and local schools.
also as a cash revenue local businesses could seasonally sponsor individual trees with plaques "sponsored by business x"
volunteers, local community groups and schools
try to utilise any local community groups such as garden allotment groups, housing estate communities etc in providing manpower in daily and seasonal upkeep of the parks. children could be taught how to shape and prune trees and planting. seedlings could be then given to the participating children to plant elsewhere.
the orchard
minimum orchard tree type requirement would consist of 3 types of apple, 1 pear, 1 plum, 2 nut and 1 special. though these types may need 2 different species or multiple of for pollination. you do get self fertile pollinating varieties and these could be used to reduce number of trees. the types are 1 red, 1 green/golden and 1 cooking apple - eg conference or comice pears - eg victoria plum- eg cob nut/hazelnut and almond - by special i mean something like fig tree or guava tree.
if space was no problem then i would like as many different varieties fruits and nuts as possible for climate conditions and try to include a rare native british fruit tree in all parks
for space limited areas in an urban concrete environment then trees planted in giant pots sunk into the ground or raised pathways around the pots/trees. The reason for pots is so each pot can be filled with the correct soil/nutrients/ph for each individual tree. otherwise trees could be planted directly into soil if concrete areas are removed/cleared around each tree.
the trees would be fan trained "orchard wall" and have easy access around trunk leaf/weed removal and for application of composts with permanent "T" posts for net fixing.to try produce a "orchard wall" of fruit at picking height with temporally fastened nets to catch fruit reducing spoilage/waste and reduce pests like wasps. each wall consisting of 3 trees, 1 with branches growing left another right with a middle tree growing left and right and grown with interlocking in mind. this could mean a tree nursery could pre train saplings to shape and are fruiting until transplanted to each park for following fruiting season.
at least 1 bee hive onsite.
park design, themes and main objective
designs would vary to the amount of space and current land usage. paths would be designed with preference to water harvesting with benches and bins along their length and in addition child play and picnic areas if space viable.
area is always put aside for composting bays,
on on all sites a shed (re purposed cargo container with solar roof ?)
larger sites could have a greenhouse or poly tunnel and sell sapling trees to gain revenue and shops could be leased with conditions eg having public toilets and controlling litter/bins in their area
The park would consist in the theme of "orchard walls" with a few individual trees left to mature naturally giving future shade? a fully mature sweet chestnut tree is huge!
the main objective is provide orchards for communities. from a few mature trees planted to managed "orchard wall" parks
for poorly locally funded projects planting semi mature trees in a natural zero maintenance scheme with wood chipping pathways to local business sponsored parks with teaching facilities and leased shops
to start natural zero maintenance scheme tree planting maybe only option. this is initially what this crowdfunder is being used for.
Crowdfunder will fund the costs in finding sites and planting trees and site overseer.
overall plan is to have a few large teaching sites with tree nursery and shops that will fund new sites.
