memorandum

to:       Town Council

from:  Charlestown Planning Commission

subject:  advisory opinion, Ordinance No. 317, WIND energy generators

date:   9/10/09

             

Under section 218-16 of the Zoning Ordinance, The Planning Commission shall file with the Town Council an advisory opinion on all proposed amendments to this Ordinance within forty-five days of receipt of such a proposal.  Among its findings and recommendation the Planning Commission is required to include a statement on the consistency of the proposal with the Comprehensive Plan and with each of the applicable purposes of zoning as presented in section 218-2.

We have prepared our advisory in five parts: a Summary which follows below; Consistency with the Comprehensive Plan; Consistency with the Purposes of Zoning; an explanation of Planning Commission amendments to the proposed ordinance; and suggested amendments to the proposed ordinance.

 

Summary

The Planning Commission finds that the proposed wind ordinance as written, and the process used to create it are not in compliance with CharlestownÕs Comprehensive Plan and with the applicable purposes of zoning.

 

The Planning Commission supports the construction of wind turbines in Charlestown as long as there is public out reach and a demonstration of public support; a study of wildlife impacts and mitigation of those impacts where they exist; and protection of surrounding residents or some benefit or tradeoff to compensate for change for those living nearby. The Planning Commission also recognizes that there may be a great difference in the impacts of a 5kw or 10kw turbine that a homeowner might install and a 400-foot high or greater utility scale turbine. We believe that a zoning ordinance for wind should address those differences.

 

Wind turbines and met towers are allowed currently by zoning and applicants can apply under applicable sections of the cell tower ordinance. In the short term, the Zoning Board could easily use this proposed ordinance as guidance in granting a special use permit for a pair of wind turbines.

 

The Land Use, Services and Facilities, and Implementation elements of CharlestownÕs Comprehensive Plan all contain the following language ÒAmend the zoning ordinance to require a special use permit for installation of wind turbines and meteorological towers for residential, commercial, or municipal use.Ó The Town Council is proposing an ordinance that exempts several classes of turbines from special use permit, site plan review, notice to abutters, and in some cases makes the Town Council the body that reviews and approves development proposals.

 

The Implementation Element of the Comprehensive Plan describes the actions that should be taken to implement the Comp Plan and the Commission or Department responsible for that action. The Implementation Element gives the responsibility for this amendment entirely to the Planning Commission. The Planning Commission is being allowed to comment on this ordinance as is required by state law, but we were not involved in writing it, we do not support it as written, and this process does not follow the Implementation Element of the Comprehensive Plan.

 

The Land Use Element of the Comprehensive Plan has two stated goals; one is to ÒEncourage public participation throughout the process, including the business community, interest groups, and residents.Ó State law has changed to allow direct sale of electricity by individuals. We think that the Comprehensive Plan may not technically have to be amended since it does say wind turbines by special use permit, but we think the Town should still go through the public out reach process to find out what the people of the Town want. Block Island surveyed their residents, Narragansett and DEM are doing a survey, residents of Portsmouth and other communities were surveyed. We think it very likely that the feeling in Charlestown is generally positive, but no one really knows.

 

There are some technical concerns with the ordinance as well. DEM is planning to site large turbines in Narragansett and as part of that process has released guidelines for setbacks, noise and some wildlife impacts. The ordinance the Town Council is proposing provides much less protection to neighbors and important wildlife areas than what the state is proposing.

 

We have provided you with a marked up ordinance in the event you decide to go forward immediately with this Zoning Ordinance amendment. But it is our recommendation that you return to the process of land use change that is outlined in our Comprehensive Plan. This is a process that attempts to engage and involve the public and measure public opinion before the Zoning Ordinance is changed in ways that may change the landscape of the town. Those changes may in fact be very positive, but the process used for this amendment has only allowed limited involvement by the Planning Commission and even less involvement by the public.

 

Consistency with the Comprehensive Plan

As part of an advisory opinion we are required to find consistency with the Comprehensive Plan.

The Charlestown Comprehensive Plan update was adopted by the Town Council on October 16, 2006 and approved by the State Department of Administration on April 28, 2008. We did talk about wind power when we worked on the Comp Plan update in 2005. At that point turbines to provide energy to an individual home or business or school were all that were imagined. What was allowed at that time was limited to net metering. Utility scale (sometimes called industrial scale) turbines were not fully contemplated. Since that time there have been changes in State Law to allow the direct sale of electricity by individuals; and now there are new government grants and changes in taxes to make it more economically feasible.

 

In the Land Use element of the Comp Plan, under Policies and Actions there is a bullet for wind power under policy 7.

LAND USE GOAL

Encourage public participation throughout the process

POLICIES / ACTIONS

Policy 7: Encourage sustainable land uses that support protection of the aquifers and reflect green space development.

¤      Amend the zoning ordinance to require a special use permit for installation of wind turbines and meteorological towers for residential, commercial, or municipal use. (See Services and Facilities Policy 16).

 

Although this proposed ordinance amendment may require a special use permit, it also exempts many applicants from the special use permit. Since the Comprehensive Plan specifically states that the zoning ordinance should be amended to require a special use permit for wind turbines, then this ordinance which exempts industrial scale turbines and other turbines from special use permit and site plan review is not in conformance with CharlestownÕs Comprehensive Plan.

 

The Services and Facilities element of the Comp Plan also mentions wind under its Policies section.

 

o     Consider use of wind energy to harness one of CharlestownÕs natural resources, wind, to reduce municipal energy costs

 

o     Apply for federal and state funding to investigate wind and other sustainable energy opportunities.

 

o     Consider role of wind and other sustainable energy sources to eco-tourism in Charlestown.

 

¤      Provide comment to proposals by state and federal agencies and private development for wind energy projects located both on and offshore. Issues could include aesthetic, environmental, fiscal, and tourism impacts.

 

¤      Amend zoning ordinance to require a special use permit for installation of wind turbines and meteorological towers (See Land Use Element Policy 7).

 

Here again there is a requirement for a special use permit for both wind turbines and met towers. Both of these Comp Plan elements are supporting, even promoting, wind power and yet they say to do so with a requirement for a special use permit. There also is guidance here to consider aesthetic, environmental, fiscal, and tourism impacts.

 

The Implementation Element of the Comprehensive Plan describes the actions that should be taken to implement the Comp Plan and the Commission or Department responsible for that action. It lists the following action: Amend the zoning ordinance to require a special use permit for installation of wind turbines and meteorological towers for residential, commercial, or municipal use. The Implementation Element gives the responsibility for this amendment entirely to the Planning Commission.

 

The Planning Commission is being allowed to comment on this ordinance as is required by state law, but we were not involved in writing it and we do not support it as written and that certainly does not follow the Implementation Element of the Comprehensive Plan.

 

The Land Use Element of the Comprehensive Plan has two stated goals: To protect the natural and cultural resources and rural character of the Town while providing the housing, economic base, and services necessary for the broad range of residents to enjoy the high quality of life associated with the Town; Encourage public participation throughout the process, including the business community, interest groups, and residents.

 

We think utility scale wind turbines and the number of possible turbines go beyond what the public might have imagined just 4 years ago. As we mentioned before, state law has changed to allow direct sale of electricity by individuals.

 

We think that the Comprehensive Plan may not technically have to be amended since it does say wind turbines by special use permit, but we think the Town should at least go through the public out reach process to find out what the people of the Town want before we change the townÕs landscape. Four years ago wind turbines were expected to be for individual use in this area. You need to engage the people and find out how they feel about utility scale turbines, how many they think we should have, how close do they want to live to a wind turbine and lots of other questions. Block Island surveyed their residents, Narragansett and DEM are doing a survey, residents of Portsmouth and other communities were surveyed. We think it very likely that the feeling in Charlestown is generally positive, but no one really knows.

 

Changes in ordinances that have the potential to radically change the landscape, even in positive ways, should only be done after soliciting and considering public input. A public hearing is not the same as public outreach. Most people in this town have never been to a Town Council meeting and are not likely to come, but they might respond to a survey.

 

Therefore we find that the ordinance itself and even the method used to develop and write the ordinance do not comply with the Land Use, Services and Facilities, and Implementation elements of CharlestownÕs Comprehensive Plan.

 

State law requires that we comply with our Comprehensive Plan

 

45-22.2-13 Compliance.

(c) For those municipalities with comprehensive plans approved pursuant to this chapter all municipal land use decisions shall be in conformance with the approved municipal comprehensive plan.

 

Consistency with the Purposes of Zoning

As part of an advisory opinion we are required to find consistency with the purposes of Zoning.

 

As part of an Advisory Opinion we are required to (2) Include a demonstration of recognition and consideration of each of the applicable purposes of zoning as presented in ¤ 218-2, Purpose/consistency with Comprehensive Plan/state laws.

 

¤ 218-2. Purpose/consistency with Comprehensive Plan/state laws.

A. Comprehensive Plan. The Zoning Regulations set forth in this Ordinance are adopted to be consistent with the Town of Charlestown Comprehensive Plan 1991, and any amendments thereto. The Regulations are made with reasonable consideration, to preserve the rural character of the Town, to encourage the most appropriate use of land, to enhance the beauty of the community, to be consistent with the RI CRMC SAM Plan and to protect the character of neighborhoods. This Ordinance shall be construed in a manner that will further the implementation of the goals and policies and applicable elements of the Town of Charlestown Comprehensive Plan 1991, and any amendments thereto.

The Planning Commission members have their own personal opinions about wind turbines with respect to beauty. But without public outreach, modeling to see how much land is available to large turbines, and computer aided visioning to see what that will look like, we canÕt tell you the cumulative impacts of wind turbines on Òthe rural character of the TownÓ or Òthe beauty of the communityÓ. We think the setbacks proposed in the ordinance are not sufficient to Òprotect the character of neighborhoodsÓ if there is not considerable public support to have them sited near houses.

B. Purposes. Adopted pursuant to R.I. Gen. Laws 45-22.2 for the following purposes that are intended to be given equal priority and are numbered for reference only:

(1) Promoting the public health, safety, and general welfare.

Rhode IslandÕs Terrestrial Wind Turbine Siting Report, includes the following advice for setback distances, ÒUntil a scientific risk based standard is developed, DEM should consider a siting-criteria for placement of a wind turbine near property lines, permanent residential structures, roads and trails that would be 1.5 times the hub height plus the rotor radius. This is the distance recommended in Massachusetts and a number of other states. This would provide for an adequate margin of safety factor in the event of a structure failure.Ó

 

The ordinance you are proposing has only a 1.1 setback to property lines and no setback for residential uses on the property where the turbine is located. The ordinance you are proposing would provide less protection to public health and safety than the State is recommending for itself.

(2) Providing for a range of uses and intensities of use appropriate to the rural character of the Town and reflecting current and expected future needs.

The question of whether Wind Turbines are appropriate to rural character is one that we need to go to our residents and visitors with. The Planning Commission does not think there has been adequate visioning to know what impact large or utility scale turbines will have on the perceived character of the town. Many people find them beautiful, but will they change the character in ways that make people decide not to summer here or will they attract tourists?

(3) Providing for orderly growth and development that recognizes:

(a) The goals and patterns of land use contained in the adopted Comprehensive Plan and foster the Plan's implementation.

Depending on whether you view turbines as works of art or industrial development you may find that these enhance or violate the patterns of land use. Very little of the Town is zoned Industrial. This is an industrial use at the utility scale, but it may be well accepted again depending on public opinion, which has never been measured with a scientifically based survey.

(b) The natural characteristics of the land, including its suitability for use based on soils characteristics, topography, and susceptibility to surface or groundwater pollution;

We believe that the impacts of wind turbines on land are small since the area on the ground for a foundation and fencing etc., is a small area. So we believe they will have a neutral impact on surface or groundwater pollution. Where they are proposed to be the only use of a parcel of land they would have nearly the same benefit to ground water as open space and could in that way benefit the long term quality of surface and groundwater.

(c) The values and dynamic nature of coastal and freshwater ponds, the shoreline, and freshwater and coastal wetlands;

In terms of water quality and quantity our analysis would be the same as (b) above.

(d) The values of unique or valuable natural resources and features;

In our research and in our discussions with staff at the local US Fish and Wildlife Service we have learned that wildlife impacts from wind turbines are greatly reduced from what they were in older designs. Still USFWS has commented that studies should be undertaken to determine migratory paths of birds and especially bats. Bat mortality from large turbines can be extreme as they seem to be attracted to turbines and their lungs explode from the air pressure differences near turbines. Bats are extremely important in mosquito control and their populations are already under great pressure from disease. We have asked for mitigation measures in the wind turbine operation. The ordinance as written has no provision for a meaningful study of bird and bat impacts and we think that is a flaw.

The DEM siting guidelines contain the following: ÒThe Division of Fish and Wildlife analyzed the possible impacts of wind turbines on avian resources. In their analysis, they suggested consideration for a 100-200 yard buffer along the coast. Young passerines often get blown off course, especially during fog events and head for shore at daylight. They are often exhausted and stop at the first available cover near the dunes. The Division also indicated DEM should avoid siting a wind turbine on East Matunuck Beach due to the piping plover issue.Ó

 

The proposed ordinance has property line setbacks, but no setbacks for coastal avian impacts. Again this is less natural resource protection than the state is proposing and is not addressed in your ordinance.

(e) The availability and capacity of existing and planned public and/or private services and facilities;

Whether National Grid will eventually need to upgrade or add transmission lines because of terrestrial wind turbines in Charlestown is unknown. That is the kind of modeling that needs to be done. We need to decide if we want to permit so many utility scale turbines that we need bigger transmission lines which would have more impact on community character than the turbines themselves.

(f) The need to shape and balance urban and rural development; and

(g) The use of innovative development regulations and techniques.

(4) Providing for the control, protection, and/or abatement of air, water, groundwater, and noise pollution, and soil erosion and sedimentation.

Noise will be a major issue in siting wind turbines. Setting noise standards through regulation may not take into account site conditions such as vegetation, which acts as a noise suppressor and background noise such as traffic, wind noises and if at an ocean setting, the sound of the waves on the beach. Some ordinances have required a site-specific noise study to be conducted in the vicinity of the installation of a wind turbine. The noise study would allow for actual measurements of background noise levels and would also take into account impacts of vegetation. The noise study would account for local conditions and would determine if the wind turbines could meet noise standards prior to construction of the turbines.

 

The proposed ordinance does not require any study of predevelopment conditions and the noise levels allowed are more consistent with denser development noise levels than rural noise levels. Depending on siting, the wind turbines may have little impact on noise levels, but the ordinance does not provide enough protection or enough incentive to acquire the best available technology in terms of noise protection.

(5) Providing for the protection of the natural, historical, cultural, and scenic character of the Town or areas therein.

Again, there needs to be modeling done (before an ordinance can be passed) of the possible number of large turbines and the cumulative visual impact of those turbines to know how it impacts scenic character. And public opinion may support a change in the scenic character if that is coupled with the threat of climate change and wars fought over fossil fuels. Presently public opinion in Charlestown is unknown.

(6) Providing for the preservation and promotion of agricultural production, forest, silviculture, aquaculture, timber resources and open space.

Where wind turbines are proposed to be the only new use on a parcel of land they could be used to provide the financial means to preserve land for agriculture, forestry or open space.

(7) Providing for the protection of public investment in transportation, water, stormwater management systems, sewage treatment and disposal, solid waste treatment and disposal, schools, recreation, public facilities, open space, and other public requirements.

(8) Promoting a balance of housing choices, for all income levels and groups, to assure the health, safety and welfare of all citizens and their rights to affordable, accessible, safe and sanitary housing.

(9) Promoting safety from fire, flood, and other natural or man-made disasters.

(10) Promoting quality in design of private and public facilities.

(11) Providing for coordination of land uses and resources with contiguous Towns, the State, the Narragansett Indian Tribe, and other agencies, as appropriate.

(12) Providing for efficient review of development proposals, and to clarify the zoning approval process.

(13) Providing for procedures for the administration of the zoning ordinance, including, but not limited to, variances and special use permits.

This ordinance contains a basis for exemptions from special use permits that we can find in no other wind ordinance.

(14) Promoting an economic climate that increases quality job opportunities and the overall well-being of the Town.

Allowing wind turbines may not promote jobs in Charlestown, but it does promote energy independence and it may provide a financially viable use of land that is more desirable than other uses.

---

As part of an advisory opinion we are required to find consistency with the Comprehensive Plan and with the purposes of Zoning which we have done above. We have also marked up the proposed ordinance with suggested changes. Those markups bring the ordinance closer to consistency with the Comprehensive Plan and the purposes of zoning, but that doesnÕt mean that we recommend its adoption if it is amended or that those changes bring it into full conformance with the Comp Plan or purposes of Zoning. But if the Town Council chooses to ignore our advisory and pass an ordinance, then we would hope that you would make our suggested changes to the ordinance to at least move it in a direction of compliance and to better protect natural resources and the character of the community.

 

Explanation of Planning Commission amendments to the proposed ordinance

3. Definitions

The definitions used in the proposed ordinance for Small and Large Wind Facility are industry standard for utility scale and non-utility scale turbines. The new wind turbine installed at New England Institute of Technology is a 100kW turbine. This is small perhaps by industry standards, but not by community standards. We have chosen a cut-off of 20kW for our definition of small. Most residential turbines will be in the 5 to 10kW range, so even 20 may be too large, but certainly 100 should not be installed without a special use permit as this ordinance allows. We have added a definition of Utility-Scale Wind Facility.

 

3. Wind Facilities Exempt from Special Use Permit Requirements

As we mentioned previously, the Comprehensive Plan direction was for a requirement for special use permit. All zoning decisions are appealable, no matter who makes the decision, even a building permit is appealable. Using this exemption and the process of Town Council review of a land development we believe makes appeal more likely, and perhaps more successful.

 

5. Site Control

The proposed ordinance is copied from the ordinance from Quincy Massachusetts that in turn is based on the Massachusetts model ordinance. Both of these ordinances require this site control language for large turbines. We have added this only for Utility-Scale.

 

2. Setbacks

The proposed ordinance language is nearly identical to the Quincy Massachusetts ordinance except in terms of setbacks. That ordinance, the Massachusetts model ordinance and most model ordinances require the 1.5 setback and some require more. We require a 1.5 setback for cell towers. These setbacks are not just fall zones. They allow an abutting property owner to have enough of a setback to not perceive the tower or turbine towering over them and allow them to see that they are not in any possible fall zone. A setback of 1.5 is also what is advised by the state. Rhode IslandÕs Terrestrial Wind Turbine Siting Report, includes the following advice for setback distances, ÒUntil a scientific risk based standard is developed, DEM should consider a siting-criteria for placement of a wind turbine near property lines, permanent residential structures, roads and trails that would be 1.5 times the hub height plus the rotor radius. This is the distance recommended in Massachusetts and a number of other states. This would provide for an adequate margin of safety factor in the event of a structure failure.Ó

 

4. Noise

These (in yellow) are the noise levels advised by DEM for their turbines. The noise levels in the proposed ordinance are consistent with more urban areas.
