Greenbelt
- Urban outer limits:
- Greenbelt to limit gradual expansion
- Transport routes and nodes
- Agricultural land and villages
- Scattered brownfield sites
- Urban lungs?
Urban lungs?
- Potentially cleaning the atmosphere?
- Urban heat Island effect may draw replacement air inwards as urban plume rises in summer
- But urban canyons will push air above roof level
- Pollution likely to stay at street level in winter
Greenfield Site
- Previously undeveloped sites
- Flood plain that should not be developed
- despite government letter to planners and
- Despite engineers who think they can
- Agricultural land that may be full of chemistry
- May need Bioremediation to clean up
- Change of use to housing required ‘nutrient-neutrality’.
- But Conservative Government decided to pollute the rivers again after voting for water companies to discharge sewage.
- Organically farmed land free of chemistry
- Development risks destroying or decanting any existing biodiversity, licenses permitting.
Brownfield Site
- Previously developed site, might be:
- Occupied building humans or nature
- Building to reoccupy, retrofit, refurbish, extend, adapt, reuse
- Derelict building being consumed by nature
- Building materials resource bank
- Deconstruct, reclaim and reuse
- Demolition materials wasted and landfilled
- Carbon burp or hiccup from wasted materials going to landfill and buying new to replace them
Self-build and brownfield
- Aspire to find brownfield sites:
- Will they be cheaper? I have no idea
- Very much depends on what is on the site
- Developers will try to avoid them, looking after profit margins
- Aspire to reuse existing buildings:
- That could save materials costs: Brexit Covid and Ukraine pushing prices ever higher
- But retrofit is usually more expensive £/m2
- Try to reuse as much materials as possible
- Landfill is expensive too:
- £1600 value of average 8m3 skip of materials
- Let alone labour filling skip, skip hire, gate fee and landfill tax
Existing buildings
- You may need guidance on what to do with historic buildings:
- Listed, Conservation areas and Ancient Monuments
- Pre 1919 historic wall construction
- Solid walls need special attention
- Better choice of materials to be compatible
- Breathing construction
- Avoid plastics and cement
- Using tree and biobased breathing materials
Self Build and Greenfield
- Restrictions are down to the Planning officers
- Probably no Conservation Officers
- Environment Agency (but no teeth)
- Avoid flood plains or use stilts or floats
- Respect carbon campaigns
- Build environmentally:
- Healthy Environmental Resourceful Appropriate Competent Effective Yardstick Construction
Biodiversity Net Gain
- Biodiversity (broad mix of nature supporting each other)
- Biodiversity related to development sites
- Gain: encourages more nature at end of project
- Net Gain is a bit of greenwash
- There must be more after development than before
- But need to protect, maintain, reinforce existing biodiversity, not move it on
- Planting saplings will not replace 40-year-old trees for another 40 years
- Wrong bats or bird boxes for the species won’t help
What Biodiversity exists?
- Understand what you already have
- What enables it to be there?
- What is important to its persistence?
- Protect and do not destroy it
- Add to and reinforce it
- but not to unbalance it
Existing Biodiversity
- May be:
- Flight paths/navigation routes:
- tree lines hedge rows
- Forrage-ing grounds, ponds and woodland
- Food sources: nectar flower beds, trees, supported insects
- Existing roosts or nests
- Legally protected as an indicator species
- £5000/bat fines or imprisonment
- For disturbance interference and entrapment
Topsoil
- Is a precious commodity
- It has taken centuries to create
- Its full of life: bacteria, insects, worms
- Don’t scrape it and stockpile it too deep
- 1m maximum (weight, water, air)
- Keep it alive
- Reuse it on the same site or sell excess
Turf and plants
- Wild-turf especially
- Plants: Dig out and pot up protect for reuse later
- Use turf to cover topsoil stockpile
- Supress weeds
- Keep it alive
- Relay it later on reused topsoil
- Excess: sell on websites FreeCycle etc.
Trees
- Indigenous species are very important
- English Oak can support up to 380 different species and many instances of each
- Lime trees support moth that support bats
- Many others support many others
Don’t investigate yourself
- Get a survey done by biodiversity experts, yes it will cost you
- Don’t use lights or sticks to find out what is inside dark cavities
- Determine quantities and which species
- Then support them with all year round appropriate and effective provisions and accommodation
Feedback
- These files are created by generalists with a big dollop of green flavour
- These files are updated from time to time
- We are not experts so from time to time these file may get out of date or may be wrong.
- If you feel that we have got it wrong please let us know so we can put it right
