Lewisboro City Zoning Code

ARTICLE XIII

Solar Energy Systems

§ 220-91 Authority; purpose.

A. 
Authority. This article is adopted pursuant to § 261 through 263 of the Town Law and § 20 of the Municipal Home Rule Law of New York State (NYS), which authorize the Town to adopt zoning provisions that advance and protect the health, safety and welfare of the community and, in accordance with the NYS Town Law, "to make provision for, so far as conditions may permit, the accommodation of solar energy systems and equipment and access to sunlight necessary therefor."
B. 
Statement of purpose. This article is adopted to advance and protect the public health, safety and welfare of the Town by creating regulations for the installation and use of solar energy generating systems and equipment, with the following objectives:
(1) 
To take advantage of a safe, abundant, renewable and nonpolluting energy resource;
(2) 
To decrease the cost of electricity to the owners of residential and commercial properties, including single-family homes;
(3) 
To increase employment and business development in the Town, to the extent reasonably practical, by furthering the installation of solar energy systems;
(4) 
To mitigate the impacts of solar energy systems on environmental resources such as forests, wildlife and other protected resources;
(5) 
To create synergy between solar and other stated goals of the Town;
(6) 
To decrease the use of fossil fuels, thereby reducing the carbon footprint in the Town;
(7) 
To invest in a locally-generated source of energy and to increase local economic value, rather than importing nonlocal fossil fuels;
(8) 
To align the laws and regulations of the Town with several policies of the State of New York, particularly those that encourage distributed energy systems;
(9) 
To become more competitive for state and federal grants and tax benefits;
(10) 
To make the Town more resilient during storm events; and
(11) 
To aid in the energy independence of the Town as well as the country; and to diversify energy resources to decrease dependence on the energy grid.

The amount of the cash deposit, bond or other security shall be 125% of the cost of removal of the solar energy system and restoration of the property with an escalator of 2% annually for the life of the solar energy system. The decommissioning amount shall be reduced by the amount of the estimated salvage value of the solar energy system.
(2) 
In the event of default upon performance of such conditions, after proper notice and expiration of any cure periods, the cash deposit, bond or other security shall be forfeited to the Town, which shall be entitled to maintain an action thereon. The cash deposit, bond or other security shall remain in full force and effect until restoration of the property as set forth in the decommissioning plan is completed.

The decommissioning plan must be completed within 360 days of notification.
(2) 
If the owner and/or operator fails to comply with decommissioning upon abandonment of the solar energy system, the Town may, at its discretion, utilize the cash deposit, bond or other security for the removal of the solar energy system and restoration of the site in accordance with the decommissioning plan.
P. 
Decommissioning.
(1) 
Solar energy systems that have been abandoned and/or not producing electricity for a period of one year shall be removed at the owner and/or operator's expense, which, at the owner's option, may come from any security made with the Town as set forth in this Subsection N above.

The decommissioning plan shall state that the site shall be restored to as natural a condition as possible within six months of the removal of all equipment, structures and foundations. Such restoration shall include, where appropriate, restoration of the surface grade and soil after removal of all equipment and revegetation of restored soil areas with native seed mixes.
Q. 
Ownership or operator changes. If the owner or operator of the solar energy system changes or the owner of the property changes, the Special use permit shall remain in effect, provided that the successor owner or operator assumes, in writing, all of the obligations of the Special use permit, site plan approval and decommissioning plan.
