Small Wind Turbines

Development & Building Approvals

Draft Regulations for

Industrial, Commercial and

Special Purpose Districts

May 2013

Onward/ By 2020

Project Purpose

•To more clearly facilitate non-residential urban wind turbines

•Industrial Areas•Commercial Areas•Special Purpose Areas (parks, schools, infrastructure)

•To define application requirements•To define how applications will be evaluated•To coordinate with other agencies with authority

Development & Building Approvals May 20132

Why non-residential areas?

•Project focus is on non-residential areas•Trial areas and pilot projects•Potential for lesser impacts on adjacent landowners•Larger parcels may allow for mitigation options

•Future project phase likely to address residential parcels

•In the meantime, applications can be made•will be evaluated as “Power Generation Facilities”

Wildlife Impacts - birds

•Mitigation – best practices•Avoid areas of key conservation•Underground transmission cables•Eliminating guy wires and lattice poles•Eliminating lighting•Pre-construction wildlife assessments

•Mitigation – site specific•Monitoring post-construction•Operational practices – halting operation in key periods


Wildlife Impacts - bats

•Mitigation – best practices•Limiting allowable turbine size to prevent pressure

changes•Avoid areas of key conservation•Underground transmission cables•Eliminating guy wires and lattice poles
