See note on environmental consultants in Landscape Guide. You may be surprised to find a note on environmental assessment in a website dealing with gardens - but please read on!
The problem is that when real estate is developed for housing, the architects, realtors and planners think about the houses AND NOT ABOUT THE GARDENS. This results in almost all new housing projects being developed without good garden spaces, especially in towns. The solution is to make an environmental assessment of the garden space a key aspect of the Environmental Impact Assessment for the project. Every garden owner should argue for the appointment of landscape architects as environmental consultants on housing projects.
