DESIGN FOR ECOLOGY

CONSTRAINTS AND OPPORTUNITIES OF ECOLOGY

The parameters around ecology are established by the Moonlight Basin Community guidelines. The Design Review Board and the owner are to work together to ensure the building is developed within guidelines. The building envelope may not exceed 40% of the total Residential Site Area. This ensures that the majority of the site isn’t modified and that the ecology stays intact. Site utilities are to be installed underground on alignments that minimize grading, tree cutting and other site disruption, and are only allowed to cross areas outside of the Building Envelope using the least disruptive alignments. Where disruption has occurred, comprehensive revegetation of those areas is required.The DRB must approve tree removal and/or selective tree thinning within the Building Envelope as outlined within these Guidelines. On a case-bycase basis, the DRB may also approve tree removal and/or thinning outside the Building Envelope for fire mitigation, view corridors, or solar exposure,provided it does not impact off-site views. Unauthorized removal, thinning or cutting of trees will result in the issuance of fine.

Grading is to be designed to minimize impacts on the Residential Site and blend Improvements into existing landforms. Except for driveways and utility lines, grading is not permitted outside of the Building Envelope. > Grading designs that use natural and/or curvilinear shapes help to blend graded areas into the natural landscape. > Straight and angular solutions abruptly contrast with the form of the natural landscape and should be avoided. > Slopes should not exceed 2:1, unless it can be demonstrated a steeper slope will not erode.

> Disturbed areas are to be revegetated to blend naturally into the surrounding environment.

> Site designs are to preserve existing drainage patterns and minimize erosion and sediment transport to minimize downstream water quality impacts. > Storm water runoff should be managed on-site to the greatest extent feasible by using environmentally sensitive storm water management practices Exterior lighting is to be kept to a minimum to preserve the visibility of the night sky and maintain a residential-quality night environment.

> Exterior lighting is permitted to the extent required for safety. All exterior lighting should meet the standards to be dark-sky compliant (i.e., received the fixture seal of approval by the

International Dark Sky Association). > All exterior light sources are to use downward facing, horizontal cut-off fixtures, which hide the light source.

Uplighting is not permitted. > High-efficiency exterior lighting is recommended.

> Motion detectors may be used where appropriate. > After installation of exterior lighting, all lighting is to be tested by the electrician or lighting consultant to ensure that there is no unintended light spill or glare and written confirmation from the electrician or lighting consultant will be provided to the DRB.

> Site lighting should be designed to reflect the architectural design aesthetic
