A.
When few natural constraints exist which limit the street layout and location, such as but not limited to steep slopes and unsuitable soils, streets should have an east-to-west orientation to the greatest extent possible with acceptable variations of 10º northwest and 25º to the southwest of due east in order to provide for orientation of buildings to the south and thereby encourage the use of solar energy systems.
B.
All development should be designed to encourage energy conservation:
C.
Windbreakers of evergreen plants are recommended for planting on northeast and northwest exposures where there are no conflicts with visibility or safety. Deciduous trees are recommended on southern and western exposures.
D.
Window openings on northern exposures should be limited in size and number.
E.
Solar access of adjacent buildings shall be protected to the extent of the yard requirements provided, unless the Board so determines that solar easements are necessary to ensure an energy-efficient plan, in which case solar easements shall be provided.
F.
For the purpose of this chapter, solar collectors shall not be subject to the maximum height regulations of the district, but their height shall not exceed 20% of the maximum height permitted.
