1.0 THE RECENT PAST
Farmington is a community in transition. In fact, it has been in transition for some time. Although geographically on the fringe of the New Hampshire Seacoast Region, Farmington has been dramatically impacted by the surge in population in that area. As real estate prices have risen in the Seacoast and other parts of Rockingham County, many people have moved further inland seeking more moderately priced housing. This has brought many new individuals to Farmington.
In 1970 the US Census recorded a population of 3,588 people in Farmington. Today that figure is estimated by Applied Economic Research (AER) to be on the order of 6800, an 89% increase in slightly over thirty years. Growth in Farmington exceeded that in Strafford County in general, albeit only slightly, in each of the decades between 1970 and 2000.
Farmington’s growth has not been even, in terms of the economic characteristics of the new citizens. In 1990, Farmington’s median household income ($31,112) was 95% of the same figure for Strafford County. In 2000, the current figure ($40,971) was only 91% of the county median household income. It would appear that many of the new residents have been at the low and moderate end of the income scale.
Between 1990 and 2000, Farmington issued building permits for 213 new housing units. Of those permits, 46% of them were for mobile homes. This is the largest concentration of new mobile homes of any community in the area, except for the City of Rochester, which had 48% of its growth in mobile homes. On average, mobile homes represented only 18% of the new housing units in Barrington, Middleton, Milton, New Durham, and Strafford.
At the same time that Farmington has been receiving new residents who are living in lower value residential units, it has been losing employment, both in raw numbers of jobs and as a percentage of jobs in the region. Between 1993 and 2002 Farmington had a net loss of nearly 17 jobs for a current total of some 1600 and a loss of some 255 from its peak employment of 1855 positions in 1996. Its share of the regional job base declined as well, from 4.2% in 1993 to 3.7% in 2002. Rochester, by contrast, saw its percentage of regional jobs hold fairly steady, dropping only from 78% in 1991 to 77% at present.
These are important issues for Farmington. A larger population base in the community requires additional services. And yet, Farmington’s new taxable property is largely in lower value
Vision 1- 1 Farmington Master Plan ~ 2005 residential units, not in the higher value commercial and industrial facilities that are used to house an expanding employment base. These circumstances set the stage for a series of questionnaires and visioning sessions undertaken by the Farmington Zoning and Master Plan Committee beginning in the autumn of 2003.
2.0 THE PRESENT
Despite its recent growth, Farmington retains its “small town” feel, and much of its rural character. People like that. They like knowing their neighbors. They like the way people volunteer and help each other out, both as individuals and through a variety of social and civic groups. They like the multi-generational nature of many of the activities here, and the variety of people, families, and income levels present in the community.
People like Farmington’s downtown, with its village character and layout. They like the village’s architecture. There is a concern about the low level of business activity here, however. There is a concern that this lack of economic vitality is leading to a lack of reinvestment and maintenance in both pubic and private properties. They cite both buildings and sidewalks that need repairs. There is a concern about enforcement of building and life safety codes in this area.
People are concerned about the lack of employment opportunities in Farmington in general. They are concerned about this both from the economic impact on individuals and families, and from the impact on the tax base. People are concerned about the degree that increased demands on services will generate increased tax bills for residential property owners. They do not wish to see Farmington become just a bedroom community.
People are concerned about the amount and the rate of population growth in Farmington. They are concerned about it changing the social dynamic of a small town. They are concerned about its impact on the natural environment and the rural landscape. They are concerned about the economic impact of the new population growth on existing residents, absent an expanding commercial and industrial tax base.
People are concerned about a variety of social issues. Some speak of a lack of activities Older residents speak of a hesitancy to walk downtown, not only because of a lack of sidewalks and the poor condition of some existing sidewalks, but also because of loitering there by younger people. Some express concern about substance abuse in the community.
Residents are concerned about education in a number of ways. People worry about the cost – as well as the quality - of public education. Many residents don’t understand how the school district is spending their money. Others are concerned that there are not enough opportunities for adult education despite Farmington’s low educational attainment (20% lower than the state average) and relatively high drop-out rate.
3.0 THE FUTURE - A VISION FOR 2020
And yet, despite all of their concerns, there are indications that people in Farmington are becoming more hopeful about the future. They have lots of ideas and suggestions, things that
Vision 1- 2 Farmington Master Plan ~ 2005 they have seen work in other communities, things they would like to see either developed or brought back to Farmington. The Recent introduction of broadcasting of public meetings on public access cable seems to be facilitating a new sense of openness that is drawing even more people to become involved. People seem genuinely ready to work to bring some changes to bear, so as to preserve that small town atmosphere that either brought them here, or made them decide to stay here.
As Farmington has continued to grow, it has captured the energy of both current and new residents. It has developed teams and strategies to undertake a variety of activities that have helped it to retain its small town character and rural atmosphere, to expand its economic base, and to engage its citizens in a variety of social venues. People are especially hopeful that by 2020, Farmington will have benefited from the following actions:
Farmington has created a more vibrant downtown, by:
Examining alternative traffic patterns, parking configurations, building design standards and other strategies that would improve the function and appeal of downtown.
Creating a more people-friendly downtown with a community police presence.
Securing funds from outside sources with which to assist and stimulate further private investment in the area.
Farmington has created a stronger local economy, by:
Utilizing Route 11 as a center for industrial and commercial development while retaining it as an effective travel corridor.
Controlling municipal costs to help residents have more disposable income to spend locally.
Working cooperatively with state and regional economic development entities.
Creating an incubator program through which to train and assist local entrepreneurs in creating and growing existing Farmington businesses.
Pursuing creative, competitive strategies that offer new and expanding businesses features that other communities don’t offer, including grants and integrated transportation, recreation, and trail planning.
Farmington has actively worked to preserve the quality of life of residents, by:
Strengthening development regulations to both protect important natural features and to promote a higher quality of development.
Vision 1- 3 Farmington Master Plan ~ 2005 Pursuing a stronger program of building code enforcement.
Ensuring that new development contributes fairly towards the cost of the services it requires. Remaining on a par with surrounding communities with respect to the pace of development.
Implementing a comprehensive transportation plan that includes sidewalks, access management, and policies governing road maintenance and upgrades.
Residents interact with a town government that they feel is responsive and effective, because:
Municipal leaders encourage participation in meetings with town boards and committees by finding new ways to inform and engage residents.
The town has created and maintained policies that encourage openness and the contributions of residents.
The town has pursued strategies to control tax rates by increasing the assessed value of new construction and by other means.
Farmington has created more social and recreational opportunities for its citizens, by:
Tailoring the recreational program to serve junior high and high-school youth as well as the very young and seniors.
Establishing a community events area in which to host outdoor civic events, flea markets, auto shows, and fairs.
Establishing a program of quarterly public events, such as
Old Home Day Community Picnics Skating and Sledding Parties Band Concerts Bon Fires Parades
Creating and expanding a network of multi-use recreational trails, and parks linking the downtown center to a variety of in-town and out-of-town locations
4.0 AFTERTHOUGHT
A grand vision? Perhaps. Too grand for a community the size of Farmington? Absolutely not! It may be ambitious, but so be it. The point of a Vision is to be grand, to stretch ourselves, to see how all of the pieces fit together. So let’s get started!! If we only achieve 80% of the vision, we will still be better off than when we started!

1.0 INTRODUCTION
Changes in demographics, evolving housing demand, and the economic and conservation needs discussed throughout this plan are all factors that have a direct influence on Farmington’s land use patterns. Land is a finite resource, and the thoughtful planning for present and future land use is an issue for all communities. Since 1987 Farmington has regulated land uses with a zoning ordinance which is based on the Farmington Master Plan. New Hampshire RSA 674:2 II (B) requires master plans to have a vision and a land use section at a minimum. This master plan also includes several of the suggested chapters that further support the vision and land use chapters. How a community decides to use its land base clearly has a direct impact on natural resources, on community character, on transportation infrastructure, and on housing affordability, the tax base, and the cost of providing services.
Main Street Businesses
Attitudes toward the land have changed considerably over the past decade. Experience has taught us that land is a complicated resource, and that one parcel of land may be better suited to a particular use than another. Natural factors such as slope, soil, groundwater, and surface water may vary across the landscape and growing communities must take these factors into consideration when planning their future, or face a decreasing quality of life.
Farmington, along with other New Hampshire communities, is growing. With this growth come changes in land use. Fields and meadows become residential areas, or commercial sites. Forests are cleared and built upon, and new roads and other services become necessary. Land once considered undesirable for development becomes more attractive as prime sites are consumed. Steep slopes, wetlands, and other sensitive environmental areas become more susceptible to development as land becomes more and more expensive. This growth and development activity
Land Use Chapter 2- 1 Farmington Master Plan ~ 2005 reinforces the need for a master plan which can address all of these factors and illustrate how Farmington would like to grow.
The purpose of this chapter is to identify land use trends in Farmington, discuss how regulations impact such trends, and offer recommendations as to what regulatory and non-regulatory steps should be taken in the future to meet the growing housing, economic, environmental, and land use needs of the community. Existing land use is a key element to consider when attempting to predict and influence the direction of future growth. Farmington still has three distinctly different geographic areas, with each displaying different patterns and types of development. These areas are the downtown area and associated neighborhoods east of NH Route 11, the NH Route 11 Corridor, and the rural portions of Farmington west of NH Route 11.
2.0 HISTORIC LAND USE PATTERNS
Farmington is located in the northern edge of the rapidly growing Seacoast Region of New Hampshire. The community is also just south of the Lakes and White Mountain Regions. This places Farmington in a key commuter and tourist traffic corridor. Because of this unique set of circumstances, Farmington has experienced increasing development pressure, including areas along the main transportation corridor, NH Route 11. Elsewhere in the community, and overall, the largest development pressure has been from residential development.
The acreage calculations for all of the recorded land uses in Farmington can be found in Table 2- 1 below for 1962, 1974, 1998, and 2004. From 1960 to 2000 Farmington’s population grew by 91%, climbing from 3,287 to 6,303 persons. During the same general time period (1962 to 2004) Farmington’s land uses also changed, and the changes have been documented on Maps 1, 2, 3,and4 in the Appendix to this Master Plan.

This is because the process used to convert the aerial photograph data into GIS maps generates minor change from time period to time period that is capturing map quality and interpretation differences as opposed to landscape change.
Analysis of this Table also reveals that the amount of agricultural land in Farmington was reduced by 43%, and the forestlands were reduced by 7%, during this forty year time period. The largest land use changes are the 222% increase in residential land uses, and the 519% increase in industrial and commercial land uses during this time period. Figure 2-2 illustrates the trends created by changes in the amount of residential and agricultural land uses in Farmington.

3.0 EXISTING LAND USE PATTERNS
Farmington covers 23,639 acres and now displays a typical land use pattern prevalent throughout the region: concentrated mixed use development in the downtown area; an automobile-oriented highway commercial corridor; scattered rural development; and working landscapes. Overall, the community is still largely rural in nature, with a downtown village at its core. The community has experienced a great deal of land use change during the past forty years. Forestlands now account for less than 80% of the town. Meanwhile, residential uses account for more than 10% of Farmington’s land area, and industrial/commercial uses account for 1%. Residential uses impact an even larger area than Table 2-1 represents because the balance of their lots, often identified as forest or agriculture on the land use maps, are actually residential in nature.
Although the loss of agricultural lands and properties with key natural resources is of great concern to residents, the larger concern is the spread of development across Farmington’s landscape. This relatively low density development is costly to the community because of the need to provide town services to a larger area (police, fire, school busing, road maintenance, etc.), and it blurs the edges between the urban and rural portions of the New Subdivision Activity off Route 75 community. If this trend continues, the community
Land Use Chapter 2- 4 Farmington Master Plan ~ 2005 will most likely become more suburban in nature, and will risk losing its distinctly New England character.
3.1 Downtown
The original centers in Farmington were the villages in the western part of the community, but the railroad and mills drew a large portion of the population and the related activities to an area that now encompasses the downtown. The majority of Farmington’s more intense development is now east of NH Route 11. Located at the intersection of NH Routes 153 and 75, the town center is the focus of residential, commercial, governmental, and community functions. Historically, this was also where the major industrial employment opportunities were located. The industrial sector has gradually moved out to NH Route 11 due to easier access to regional and interstate transportation facilities, and the decline of manufacturing facilities in the downtown area has continued due to economic trends
The downtown area is served by public water and sewer and a well developed street network, all allowing a relatively high density of development. Although commercial development has been increasingly moving out to NH Route 11, the downtown still provides a large number of commercial and service related activities focused mainly on serving local residents,. The commercial development of downtown exhibits the characteristics of a traditional compact New England village. Commercial structures are two to three stories tall, constructed of wood and brick, and complement each other well. The downtown is the only area in Farmington that exhibits this concentrated, commercial land use pattern. Farmington’s Town Hall, police station, fire station, public library, post office, and all of the public schools are within, or directly adjacent to, the downtown area. Farmington’s major private recreational area, the Farmington Country Club, is also directly adjacent to the downtown.
Residential development in the eastern portion of Farmington is primarily in the downtown area, with the exception of Chestnut Hill Road, which is roughly parallel to Route 11 and east of the Cocheco River, and is a heavily developed residential road. Residential development in the downtown consists mostly of older, two-story homes on small lots served by both town water and town sewer. The sidewalk system is extensive throughout the downtown area. While there are some maintenance issues, walking to commercial and governmental uses is easily accomplished. There is an interest in seeing the system of sidewalks expanded, better linking the downtown, school, and recreational sites. The existing residential development on the outskirts of the downtown in this eastern section of Farmington is becoming increasingly suburban in character. Homes are generally newer than in the town center, and the lots are often larger. The houses generally sit back from the road and are surrounded by large lawns and trees.
3.2 NH Route 11 Corridor
The NH Route 11 Corridor is the major transportation feature in Farmington, and carries a large amount of through traffic heading north and south. According to the NH Department of Transportation, the average annual daily traffic on NH Route 11 continues to increase. See Table 2-3 below for detailed traffic count information from two locations. There is some seasonal variability to the traffic volumes. Because of this traffic volume and the nature of the
Land Use Chapter 2- 5 Farmington Master Plan ~ 2005 road as an arterial, the character of this corridor is different from anywhere else in the community.
Table 2-3 Farmington Traffic Counts
Location 1994 1996 1997 2001 2002 NH Route 11 at the New Durham Town Line 7,200 9,800 12,000 NH Route 11 at the Rochester Town Line 12,000 14,000 15,000 Source: NH Department of Transportation
Businesses now located on NH Route 11 cover a wide range of services including small antique shops, a state liquor store, gas stations, a pharmacy, and auto repair shops. The common characteristics among these businesses are that they are automobile-oriented and depend on passing traffic and non-resident patronage more than the businesses in the downtown. Development is generally spread along the length of the roadway in Farmington with a greater concentration along the southern section of the corridor near the Rochester town line. The intersection of NH Routes 11 and 153 has the largest concentration of development activity within the corridor, and is currently being reconstructed as a major signalized intersection. Route 11 Commercial Development This is an auto-oriented environment, and is not pedestrian friendly.
The land along this roadway has developed incrementally. Although there are undeveloped or lightly developed sections, much of it now exhibits a strip development pattern. Most of this strip development is concentrated on the road frontage and generally has little or no depth back from the road. Highway access is the primary factor driving this type of development; however, the local regulations have also been a factor. This has created an environment that lacks local character, and is starting to erode the sense of place that is Farmington.
3.3 Rural Lands
Farmington is sparsely developed west of NH Route 11, and this section of the community is generally rural in character. This portion of the community contains an Smith Farm array of valuable natural resources, and extensive recreational opportunities exist at Blue Job Mountain State Forest, Baxter Lake, the
Land Use Chapter 2- 6 Farmington Master Plan ~ 2005 various ponds in the area, and within the large unfragmented blocks of land. Approximately 90% of the land area still supports farm and forestry activities. This area supplies drinking water to the City of Rochester. The mixture of uses here presently includes low density residential, commercial, home businesses, farming, and forestry activities.
Development in this area is generally along existing roads, and the existing road network consists of a mix of paved and dirt roads in varying conditions. New development in this area tends to be on relatively large lots. New road construction has been minimal, but a number of the town roads have been upgraded and this appears to have encouraged some additional residential development in parts of the community that had previously been inconvenient to access. Public water and public sewer are not available in this area.
4.0 FUTURE LAND USE
Farmington’s desired future land use pattern should be driven by all of the previous elements. It should reflect the vision statement, which speaks of a stronger economy, of a more vibrant downtown, and of clustered and nodal development, rather than a uniform spreading of residential, commercial, and industrial activity across the community. The future land use pattern should be driven by the natural resource chapter, and by the need to protect open space and important groundwater resources. It needs to reflect the likely development pressure that Farmington will experience, and respond to it realistically, providing opportunities on a level that are consistent with those market forces.
To put numbers on that anticipated growth, assuming no significant change in regulations that affect rate of growth, present trends indicate that over the next ten years Farmington:
Will continue to grow at about seventy housing units per year;
Will likely experience a demand for fifty new acres of industrial land, with perhaps as much as 600,000 square feet of new building space; and
Will experience a demand for some thirty new acres of commercial land, again with as much as 600,000 square feet of new building space.
It should be noted that that projected growth will bring the total number of households very close to 3200. With the 2.55 persons per household that has been the norm in Farmington of late, it will likely become the home of over 8,000 people by the end of that ten year period. The nature of that anticipated growth and development, and its placement on the landscape, will be driven by market forces, by individual landowner’s preferences, and by Farmington’s land use policies and ordinances: its zoning ordinance, its site plan and subdivision regulations, its capital improvement plan, and others. Map 5 outlines how the Farmington Planning Board would like to see all of these forces brought together. What follows is a written summary of those desired future outcomes.
As envisioned by the Farmington Planning Board, after a review of the extensive community surveying and interviewing undertaken by the Zoning and Master Plan Committee, and so as to
Land Use Chapter 2- 7 Farmington Master Plan ~ 2005 achieve the Vision outlined in the beginning of this master plan, this new growth could best be accommodated while retaining the essential community character, while meeting market forces, and while protecting the community’s natural resources, as follows:
By concentrating residential development in the following areas:
In a node of single family and multi-family projects in the eastern corner of Farmington, along both sides of Governor’s Road and parts of Chestnut Hill Road. Cluster development patterns should be encouraged here.
In another node of housing off of Chestnut Hill Road, between that road and the Farmington Country Club, on the east side of the Cocheco River. Again, an emphasis on cluster development is suggested here.
In the downtown, with efforts made to redevelop the upper floors of some of the downtown commercial blocks into residential units where possible as well as upgrading some of the existing apartment buildings.
Open Space Cluster Development should be encouraged in the area around Baxter Lake.
By concentrating commercial and industrial development:
On both in-fill and on redevelopment sites in the village core. The commercial development here needs to be of a nature and scale that is consistent with the village environment.
In a nodal development pattern along Route 11 rather than in linear strips of development. The identified nodes should fit the following criteria:
• Consider the natural characteristics of the land; • Areas with existing development should be a higher priority than previously undeveloped areas; • Nodes of development should run back from the highway corridor, where conditions permit this, rather than along the highway frontage like a strip development; • Nodes of development should be separated by very low density areas; • Access management techniques should be maximized when designing access to the developable areas from Route 11, and in the design of the internal circulation system between uses.
The first two locations on Route 11 that should be considered for development nodes include:
• The area bounded by Route 11, Tappan Street, and Central Street. The uses within this node should generate a moderate number of vehicle trips. This node is seen as a logical connector between Route 11 and a strengthened downtown and could include a mix of both new and infill development of a residential and commercial nature. • The area around the intersection of Main Street and Route 11. This node could include the expansion and redefinition of the Sarah Greenfield industrial park, and could include a mix of commercial and industrial uses.
Land Use Chapter 2- 8 Farmington Master Plan ~ 2005 In all of these areas, development would be drawn to these nodes by limiting the type and density of uses along other parts of Route 11, and by adjusting the zoning in these nodal areas to offer bonuses, incentives, and increased densities to attract development to these areas. After a node has been developed the town should consider allowing higher density residential development adjacent to the back side of the node to make the most of the access point to Route 11, and the adjacent commercial activity.
Development along the west side of Route 11 is envisioned as being somewhat limited to the immediate highway corridor itself, and not spreading further west. Development along the eastside of Route 11 needs to transition from the highway to the smaller scale of the village core, and, as noted below, needs to be sensitive to natural resource issues and recreational opportunities along the Cocheco River corridor.
Extending sewer lines to these nodal areas would require significant improvements to the sewage treatment facility, and survey respondents indicated that they would only support such an extension of infrastructure if there was a detailed plan. If it is determined that new lines are needed they can be constructed by the community, or by private developers. One regulatory tool for the community to consider when the sewage treatment facility has been upgraded, and new sewer lines are needed, is a Tax Increment Financing District. This would provide a mechanism for funding these infrastructure improvements.
There is a concern within the community that greater use of the sewage treatment facility by new commercial and industrial uses could compromise the quality and safety of the community’s sludge. This issue needs to be examined further, and standards should be developed to identify which substances and levels are acceptable. If standards are in place the community can assess the potential impact of a new user on the quality of the sludge. If the impact will be too great alternative treatment options may be a possibility.
By protecting the community’s natural resource base and rural character
The community should continue to work to protect the most sensitive of natural resources in the Cocheco River valley, in the area bounded by Spring Street and Old Bay Road, in cooperation with neighboring towns, and by seeking to foster cluster development patterns in the hilly, rural landscape west of Route 11. The majority of residents (82%) responding to the survey indicated that the town should do more to preserve open space in Farmington. The majority of respondents (62%) also favor using local funds to acquire land and keep it as permanent open space. There are several large unfragmented blocks of land that Farmington shares with neighboring communities. The town should communicate with these communities to ensure that opportunities to preserve these resources are coordinated, and neither town carelessly or unknowingly impacts one of these large blocks.
In the future, the community may wish to consider whether to require cluster development patterns on properties with prime agricultural soils, over aquifers, or that contain other sensitive resources. It also may wish, over time, to discuss whether to require cluster development plans in projects over a certain number of units. This is of concern throughout all of the community, and
Land Use Chapter 2- 9 Farmington Master Plan ~ 2005 particularly so in the largely rural and undeveloped land that is west of Route 11, and in the upper reaches of the Cocheco Watershed east of Route 11.
The survey showed support for the expansion of water and sewer lines if there was a specific plan, and many respondents (46%) also indicated that they would support such expansion where it would protect natural resources. Based on this support consideration should be given to extending water and sewer lines to the Spring Street area because studies have indicated that residences in the area are a pollution source for the Cocheco River.
By requiring a higher quality of non-residential development
There is a concern that some non-residential development, particularly along Route 11 where the traveling public gets its primary view of Farmington, has not always been of the highest caliber. Not only does this create a poor image of Farmington, but it uses up valuable land resources in a manner that does not contribute as much as it might to the local tax base.
Reasonable improvements to the community’s site plan review regulations could establish improved standards for the quality of design, construction, landscaping, and parking lot configuration for non-residential properties. The creation of a design manual and design guidelines for non-residential uses outside of the downtown, similar to the one being completed for the downtown area, would help foster higher quality design.
By monitoring and evaluating the mix of housing types
As a matter of public policy, until the concentration of mobile homes in Farmington is consistent with that in other surrounding communities, Farmington wishes to permit mobile homes on individual, private lots just as they would any other form of construction, but to remove mobile home parks as a development option.
By monitoring and evaluating all growth and development
Farmington undertook this master planning effort concurrent with adopting an Interim Growth Management Ordinance in the fall of 2003. In a careful and thoughtful process it has measured its current growth against that being experienced by its neighbors. Consistent with state law, it has also evaluated its municipal facilities and evaluated its ability to provide adequate sewer and water and educational facilities.
The results of this evaluation indicate that those facilities are able to accommodate reasonable levels (approximately 70 building permits per year) of new population growth. Farmington is concerned, however, that a few large projects could start to tax some or all of those facilities.
It is the recommendation of this plan that Farmington both undertake some modest, immediate changes to its zoning ordinance, and that it prepare, on a longer term basis, a growth management ordinance with an annual building permit cap that would only be activated when certain regularly monitored criteria (such as building permits issued, school capacity, and water and sewer capacity) exceed certain pre-specified levels.
Land Use Chapter 2- 10 Farmington Master Plan ~ 2005
The Farmington Planning Board recognizes that some of these goals will require changes in its regulatory framework, but it feels that the benefits will be worth that extra effort, and it commits to working on those pieces that are necessary in order to achieve a better Farmington for all of its citizens into the future.

Natural Resources Chapter 3-1 Farmington Master Plan ~ 2005 1.0 INTRODUCTION
Farmington is a rural community with exceptional natural resources. Significant water resources, agricultural lands, and unfragmented blocks of land support the community’s health, economy, tax base, wildlife species, recreation activities, and quality of life. The type and distribution of the town’s natural resource base also influences the location and type of development that takes place within the community. Some areas of the community are better suited for a particular use than others, based on the natural resources that are present there. Agricultural Land Along Poor Farm Road
The information provided in this chapter will allow Farmington to determine compatible future uses for certain land areas, and significant resource areas that are not currently protected. Farmington, just like natural resources, does not exist in isolation. It is hoped that this chapter will alert residents of Farmington to the importance of the natural integrity of the entire region, and their role in this natural system. At the end of each section within this chapter land use implications have been identified, and potential policy actions have been suggested. The policy actions will be incorporated into the Implementation Chapter of the Master Plan to provide a work program for the town upon completion of the Master Plan. Farmington's Natural Resource Inventory is an adjunct to the Master Plan, and contains additional detail about each of the resources outlined in this chapter.
2.0 CLIMATE
Typical of Northern New England, the primary characteristic of Farmington’s climate is the ability for conditions to change very quickly. A large range of temperatures and conditions can be experienced in a single day, and are guaranteed over the course of a year. The area also experiences great differences between the same seasons from year to year. The average annual temperature in Farmington is 45 degrees Fahrenheit although it can dip well below zero for periods of time during the winter, and exceed 100 degrees Fahrenheit at times in the summer months.
During the warmer half of the year most of the precipitation comes from showers and thunderstorms. Frontal precipitation in the colder season is occasionally supplemented by coastal "Northeasters" which can bring a strong wind and heavy snowfall, and on occasion, rain or sleet. Farmington receives an average of 36 inches of precipitation annually. The average annual snowfall amount for Farmington is 63.5 inches.
Additional climate data is available at http://www.erh.noaa.gov/er/gyx/climate.shtml#daily_summary.
Natural Resources Chapter 3-2 Farmington Master Plan ~ 2005 2.1 Land Use Implications
Farmington’s climate has a direct impact on the landscape. Here are a few summary points to consider related to the climate in Farmington.
1) With precipitation distributed evenly throughout the year Farmington has the ability to replenish its many ponds, streams, and aquifers. This sustains the health of the surface waters and recharges groundwater reserves.
2) Seasonal changes contribute to the character of the region, and the variety of recreational and economic activities available. Air pollution from vehicles, homes, and commercial and industrial facilities threatens the character of our seasons, and the quality of our water. Recognition of the role local activities have on the global problem of climate change will help to preserve these distinct seasons and the industries and character they support.
3) Snow storage or “dumping” in sensitive areas can have a negative impact on the natural systems in Farmington.
4) Road salt use and storage can negatively impact natural resources in Farmington and beyond.
2.2 Potential Actions
There are an array of possible actions the Town may want to consider pursuing as it evaluates the impact of the climate on Farmington and the land use implications. This section will be used to identify the specific actions for Farmington to take upon completion of the master plan.
1) Pursue the use of alternative fuels in town vehicles and the school bus fleet. The NH Office of Energy & Planning can guide the community through such a transition.
2) Encourage carpooling and alternative modes of transportation (biking, walking, public transportation) to reduce automobile emissions in the region.
3) Work with local industries in the region, to promote alternative modes of transportation to reduce emissions.
4) Snow removed from streets and parking areas should be stored away from wetlands and water bodies. This will allow for a higher rate of filtering out of pollutants and infiltration of water as it melts.
5) Road salt should be stored in a covered facility in accordance with the U.S. Environmental Protection Agency guidelines. Snow removed from streets and parking areas should be stored away from wetlands and water bodies. This will allow for a higher rate of filtering out of pollutants and infiltration of water as it melts.
Natural Resources Chapter 3-3 Farmington Master Plan ~ 2005 3.0 TOPOGRAPHY
Topography describes surface features of the land in terms of shape, relief and relative positions of natural features. Topography is usually expressed as elevation (height above mean sea level) and slope (change in vertical distance over horizontal distance). Topography affects several natural processes, such as climate, drainage, erosion, wind patterns and vegetative growth, in turn affecting man's activities.
Farmington’s topography is a mixture of various terrain features. Farmington is mostly rolling hills East and West of the Cocheco River valley. The highest point in Farmington is Blue Job Mountain at 1,357 feet above mean sea level. The lowest point is approximately 235 feet above mean sea level at the Farmington/Rochester Town Line on the Cocheco River. There are a number of low peaks in the Western part of town including Nubble Mountain, Hussey Mountain and Chelsey Mountain. See Map 8 for additional information on Farmington’s topography.
3.1 Land Use Implications
Farmington’s topography plays a major role in the location and impact of future development in town. Here are a few summary points to consider related to Farmington’s topography.
1) River valleys are often the easiest areas to develop, and a majority of Farmington’s development exists in the Cocheco River Valley. These areas also contain all of the floodplain areas, most of the surface water bodies, and critical wetlands. Minimizing the impact of development in these areas is critical to the quality of both surface and sub-surface waters.
2) Development at higher elevations on the high ridges and lower hills in Farmington presents a different set of challenges and impacts. Without thoughtful site design, these areas can greatly impact the scenic character of the community and disrupt scenic views. Access to these areas also provides an opportunity for increased environmental impacts (erosion, increased runoff rates, longer roadways, and fragmentation of habitat to name a few).
3) The variety of topography within Farmington contributes to wildlife habitat and diversity, and recreational opportunities. Ensuring connections between these distinct areas will ensure continued biodiveristy.
3.2 Potential Actions
There are an array of possible actions the Town may want to consider pursuing as it evaluates the topography in Farmington and its land use implications. This section will be used to identify the specific actions for Farmington to take upon completion of the master plan.
1) Consider a ridgeline development ordinance to limit the impact of developments at higher elevations.
2) Pursue land protection opportunities that create corridors of contiguous open space between the currently protected lands.
Natural Resources Chapter 3-4 Farmington Master Plan ~ 2005 3) Designate topographically defined viewshed areas of high value and make open space subdivision mandatory in those areas. 4.0 SLOPE
Slope is the amount of rise or fall in feet for a given horizontal distance and is expressed in percent. A 6% slope means that for a 100-foot horizontal distance the rise or fall in height is 6 feet. The slope of the land can have a great effect on development, and percent slope can greatly impact the economic and physical feasibility of development. The steeper the slope, the more it will cost for septic systems, driveways, foundations, etc. Additionally, as the slope increases so does the potential for an increase in erosion, stormwater runoff, and nutrient movement. Poor soil conditions combined with steep slopes can present significant development constraints. See Map 8 for an analysis of slope in Farmington.
Slopes in Farmington have been placed into three categories on Map 8: below 15%, 15 - 25%, and greater than 25%. Generally, slopes over 25% are considered undevelopable. Slopes between 15 and 25 percent are difficult and costly to develop. Slopes under 15% are generally considered the upper limits for practical development.
4.1 Land Use Implications
Slopes within Farmington also play a major role in the location and impact of future development in town. Here are a few summary points to consider related to slopes in Farmington’s.
1) The majority of Farmington is covered in slopes less than 15%, which are considered developable. This will have an effect on the future development pattern of the community because large areas of the community may be fairly easy to develop in the future.
2) As steeper slopes are developed, costs increase for both the property owner and the community. Construction and maintenance of roads becomes more costly on steeper slopes. Problems with erosion, stormwater runoff, and non-point pollution are also increased.
4.2 Potential Actions
There are an array of possible actions the Town may want to consider pursuing as it evaluates the topography in Farmington and its land use implications. This section will be used to identify the specific actions for Farmington to take upon completion of the master plan.
1) Review site plan review regulations to ensure they reinforce the Steep Slope Development Standards, and reduce the impact of development on steep slopes.
2) Farmington’s regulations, relative to erosion and sediment control, should be revisited to ensure that they are following the most current “best management practices” (BMPs).
Natural Resources Chapter 3-5 Farmington Master Plan ~ 2005 5.0 GEOLOGY
The geologic history of any area is the basis for many of its natural characteristics such as topography, groundwater systems, drainage patterns, mineral resources, and origin of the soil. New Hampshire’s geologic history has formed a variety of land features and mineral resources. Plate tectonics contributed to the formation of granite bedrock. Long periods of erosion shaped the hills and mountains. Most recently, repeated glacial activity provided some finishing touches to a land that had been evolving for perhaps 400 million years. Current landscape features remind us of this rich geologic history. Ring dykes indicate past volcanic activity, fault lines demonstrate where land was uplifted by tremendous forces, and eskers, drumlins, kettlehholes, and many other features are evidence of glaciation.
Bedrock Geology
As the name implies, bedrock geology is concerned with the underlying rock or ledge. Formed hundreds of millions of years ago, Farmington’s bedrock is composed mostly of igneous rocks such as granite, and metamorphic rock such as schist. The metamorphic rock was formed under heat and pressure from many layers of mud, sand, and silt. It was later uplifted by the earth’s internal forces.
Surficial Geology
Surficial geology includes all of the deposits above bedrock. The surface layer of weathered material (i.e. soil) is not included in the study of surficial geology (for information on soils in Farmington see Section 6 of this chapter). Surface deposits are unconsolidated, loose conglomerations of rock fragments. These surface deposits in Farmington are the result of glaciation. As the glaciers advanced the bedrock was scraped and gouged, and this material was picked up and carried along in the glacial ice. This glacial advance, or scraping, did not drastically alter the topography of the area. The profiles of the mountains appear much as they did before the Ice Age. However, the glaciers did have an impact on the valleys.
As the climate warmed and the ice retreated, it deposited two major types of material—till and glacial outwash deposits. Till is composed of a mixture of soil and rock fragments that were scoured loose by the moving ice, carried for a distance, and then deposited directly as the melting ice released its unsorted contents. It is generally highly compacted and contains many large angular stones and boulders. Glacial melt waters also deposited material, but the moving waters actually sorted the material and deposited like sizes together along glacial streams or in glacial pools and lakes. These are outwash deposits. They are the stratified sand and gravel deposits that line the rivers. Outwash deposits are important economically for mining purposes, but they also serve as major groundwater-recharge areas. An example of this is the large stratified drift aquifer that exists under the Cocheco River. Glacial drumlins and eskers are common in this part of the state, giving this region its rolling topography. Much of Farmington’s gravel features have been mined. Although some mining of sand and gravel continues today in Farmington, many other communities have seen mineral mining firms turning their interest to stone assets, and as a result seeking permits for blasting to create aggregate.
Natural Resources Chapter 3-6 Farmington Master Plan ~ 2005 5.1 Land Use Implications
Farmington’s geology has an effect on land use decisions and impacts future development in the community. Here are a few summary points to consider related to the geology in Farmington .
1) The use of outwash deposits in commercial sand and gravel operations could alter the performance of these areas as groundwater recharge areas. As material is removed and the geology is altered, water will not be filtered and stored in the same manner. This could result either in a reduction in the amount of water available to future generations, or its quality as less filtering is available.
2) It is important to carefully regulate the type and intensity of future uses wishing to locate on previously mined sites. This is due to the increased potential to negatively impact the ground water resources below.
3) The impacts of sand and gravel operations are often cited as concerns. Increased truck traffic, noise, erosion, and airborne particles can create problems for abutters, and should be mitigated.
5.2 Potential Actions
There are an array of possible actions the Town may want to consider pursuing as it evaluates the geology in Farmington and its land use implications. This section will be used to identify the specific actions for Farmington to take upon completion of the master plan
1) The Town should revisit the Earth Excavation Regulations to ensure they protect natural resources more effectively.
6.0 SOILS
Soil is the portion of the surface of the earth that supports plants, animals, and humans. There are over 1,000 different soils in the Northeast with 74 of them represented in Farmington. Soils information is an intricate part of a natural resources analysis because it provides a wealth of data concerning the capability of land to support various land uses. Soils differ from one another in their physical, chemical and biological properties. Soil properties which affect its capacity to support development include depth, permeability, wetness, slope, susceptibility to erosion, flood hazard, stoniness, among others.
6.1 The Soil Survey
Soil scientists from the United States Department of Agriculture (USDA), Natural Resources Conservation Service (NRCS) have collected soil information for Farmington. As they walked the land, they regularly sampled the soil to depths of 40 inches or more, and each soil was examined for characteristics such as color, texture, structure, etc. From this information, lines were drawn on aerial photographs outlining the boundaries of the different soils. Numbers were placed within each mapping unit to identify the type of soil found.
Natural Resources Chapter 3-7 Farmington Master Plan ~ 2005 One important note in using a soils map is that changes from one soil to another are not usually abrupt, but are gradual. Thus, the line on the map represents a transition zone rather than an absolute boundary. Because of the scale of the map, mapping units are not 100% accurate. On- site soil investigations are necessary for determining exact soil boundaries.
Two publications that provide more detailed information about soils in Farmington are Soil Potential Ratings for Development dated July 1987 and written by the Strafford County Conservation District, and the Soil Survey of Strafford County, New Hampshire published by the Soil Conservation Service in March 1973.
Soil Condition Groups The 74 soil mapping unit soils found in Farmington can be broken down into 7 natural categories or groups:
Group 1-Wetland Soils These are poorly and very poorly drained soils that are wet most of the year. The water table is at or near the surface 7 to 12 months of the year. See Section 7 Wetlands for more information.
Group 2-Seasonally-Wet Soils Included in this group are moderately well-drained soils that have a water table 1 to 1 ½ feet below the ground and where the soil is wet from late fall to late spring.
Group 3-Floodplain Soils These soils are subject to periodic flooding. Their formation has been the result of sediment deposited from past floodwaters. Group 4-Sand and Gravelly Soils These well drained to excessively well-drained soils are formed in sand and gravel deposits. This group often has economic value and is found within aquifer areas.
Group 5-Shallow to Bedrock Soils These soils have formed on a thin layer of glacial till which is underlain by bedrock. Steep slopes with exposed bedrock are common in some of these soils.
Group 6-Compact Till Soils The soils in this group are well drained and have formed in compact glacial till. A hardpan layer is generally found about 2-3 feet below the ground surface. Water moves down-slope on these soils over the hardpan layer and comes to the surface as seep spots.
Group 7-Deep Loose Till Soils This group consists of well-drained sands or loamy soils that have formed in glacial till. The water table is commonly more than four feet below the ground and bedrock is more than 5 feet below the surface. The soils contain many angular stones of varying sizes.
Natural Resources Chapter 3-8 Farmington Master Plan ~ 2005 6.2 Important Farmland Soils
The NRCS has identified a subset of the soils in Strafford County that are best suited for farming. Prime farmland soils are those soils that the NRCS has determined will produce the highest yields at the lowest cost. According to NRCS, prime farmland soil:
“....has the best combination of physical and chemical characteristics for food, feed, forage, fiber, and oilseed crops, and is also available for these uses (the land could be cropland, pastureland, forest land, or other land, but not urban built-up land or water). It has the soil quality, growing season, and moisture supply needed to economically produce sustained high yields of crops when treated and managed, including water management, according to acceptable farming methods. In general, prime farmlands have an adequate and dependable water supply from precipitation or irrigation, a favorable temperature and growing season, acceptable acidity or alkalinity, acceptable salt content, and few or no rocks. They are permeable to water and air. Prime farmlands are not excessively erodible or saturated with water for a long period of time, and they either do not flood or are protected from flooding.”
In addition to prime farmlands, the NRCS has designated Farmland Soils of Statewide Importance and Farmland Soils of Local Importance. Farmland Soils of Statewide Importance are defined as:
“...land, in addition to prime and unique farmlands, that is of statewide importance for the production of food, feed, fiber, forage, and oilseed crops. Criteria for defining and delineating this land are to be determined by the appropriate State agency or agencies. Generally, additional farmlands of statewide importance include those that are nearly prime farmland and that economically produce high yields of crops when treated and managed according to acceptable farming methods. Some may produce as high a yield as prime farmlands if conditions are favorable.”
Farmland Soils of Local Importance are defined as:
“...additional farmlands for the production of food, feed, fiber, forage, and oilseed crops, even though these lands are not identified as having national or statewide importance. Where appropriate, these lands are to be identified by the local agency or agencies concerned.”
The characteristics of prime farmland make it particularly susceptible to development pressures. While the cost of producing a crop is low, so is the cost of developing these soils for residential or other nonagricultural uses. The need to conserve this soil resource is critical to the future of agriculture in Farmington. The economic viability of farming large contiguous tracts of prime farmland soils is degraded when these tracts are fragmented by development. Farming is recognized as an important part of the local and regional economy as well as part of the heritage of Farmington. Map 8 identifies the important farmland soils in Farmington and their current use. See section 10 for a discussion of the importance of retaining the option to raise local produce.
Natural Resources Chapter 3-9 Farmington Master Plan ~ 2005
6.3 Land Capability and Lot Size
Each soil-mapping unit found in New Hampshire has been rated for its ability to support a residential or commercial lot, based on a formula that has water quality as its primary concern. Potential pollution sources considered were septic systems, lawns, and impermeable surfaces. The assessment of suitability was based on a report by the NHDES entitled “Environmental Planning For Onsite Wastewater Treatment in NH”. The formula, which uses nitrogen loading as its benchmark for pollution, was applied to each soil type and a minimum soil based lot size was determined for each mapping unit. Lots on the best soils that are capable of utilizing the most nutrients onsite, require a 35,500 square foot lot, which is the minimum. As the soils decrease in their ability to utilize nitrogen, the lot sizes increase.
6.4 Land Use Implications
The soils within Farmington play a major role in the location and impact of future development in the community. Here are a few summary points to consider related to soils in Farmington.
1) Soil characteristics such as depth, permeability, wetness, and slope can be used to evaluate land to determine development suitability and dwelling unit densities.
2) Locating new development in areas without water and sewer infrastructure requires taking a much closer look at the ability of the soils on the lot to handle a well and septic system discharge. Soil information should be used as a determinant of what constitutes an environmentally sound building lot to prevent degradation of the environment and negative impacts on abutting property owners.
3) Farmland soils are a precious resource with great value to the community and the region. See Section 10 in this Chapter for additional information on this resource.
6.5 Potential Actions
There are an array of possible actions the Town may want to consider pursuing as it evaluates the soils in Farmington and their land use implications. This section will be used to identify the specific actions for Farmington to take upon completion of the master plan.
1) Base lot sizes in the rural areas of town (not served by water and sewer) on land capability. A flexible, soil based lot-size regulation should be adopted.
2) Evaluate future sewer and water line extensions on the land capability of the area being included and the desired development pattern for the community.
3) Maintain and encourage the use of the Open Space - Cluster Development Regulation that facilitates the protection of valuable farm and forest soils existing on the site by clustering the structures on other portions of the property that are more appropriate for development.
Natural Resources Chapter 3-10 Farmington Master Plan ~ 2005 7.0 WETLANDS
One of the most important, environmentally-sensitive natural resources in Farmington are wetlands. Farmington has been making progress toward the protection of its important wetland resources. The Town recently completed an inventory and analysis of the existing wetlands resources in conjunction with Moose Mountain Regional Greenways. The foresight to protect Farmington’s wetlands now will help insure clean groundwater, ponds, and streams, and a more balanced natural system in the future. Wetlands, as defined by the EPA, the Army Corp of Engineers, and the NH DES are: Wetland Area Below Blue Job Mountain
"those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions."
There are many reasons why wetlands are valuable to the community. Some of those reasons are flood control, erosion control, pollution filtration, water supply, wildlife habitat, environmental health and diversity, recreation, and aesthetics. These are but a few of the important functions wetlands perform in helping protect the quality of water, land, and the community.
Wetlands perform all of these functions with no charge to society. Dams, tertiary sewage treatment plants, water purification plants, dikes, and other sophisticated and expensive man- made water control measures all try to copy what wetlands do naturally. Each acre of existing wetland provides significant benefits to Farmington.
7.1 Wetland Delineation
Wetlands are difficult to define and delineate. Words such as swamp, bog, marsh, lowland, and floodplain are often used, but are confusing and overlapping. In New Hampshire, the yearly water cycle causes tremendous variation in the level of water in the particular area. During the spring, an area might have two feet of water on its surface while that same area in September may not have water on its surface at all. Any definition of wetlands must take this variation in water levels into account, and any delineation of wetlands requires the identification of the wetland-non wetland boundary on the landscape. For the purpose of this master plan, wetlands are defined as poorly and very poorly drained soils.
7.2 Wetland Soil Survey
A soil survey is a map on which the natural soil is identified and its distribution delineated. Boundaries of individual soils are plotted on aerial photographs after a soil scientist has traversed the land digging test holes in order to identify the soil, as discussed in Section 6 of this chapter. However, a few comments on soil drainage are necessary here.
Natural Resources Chapter 3-11 Farmington Master Plan ~ 2005 One of the characteristics soil scientists use to differentiate soil is drainage. Drainage is broken into five categories:
1. Excessively well drained – water is removed from the soil very rapidly. 2. Well drained – water is removed from the soil readily, but not rapidly. The depth to seasonal high water table is generally more than 3 feet. 3. Moderately well drained – water is removed from the soil somewhat slowly. The water table is generally within 3 feet of the ground surface for 3 months of the year. 4. Poorly drained – water is removed from the soils so slowly that the water table is at or near the surface 7 to 9 months of the year. 5. Very poorly drained – water is removed from the soils so slowly that the water table remains at or on the ground surface more than 9 months of the year.
Very poorly drained soils have a layer of muck, or peat, that overlies the mineral soil material (sand, silt, or clay). The layer of organic matter could range in thickness from a few inches to several feet, depending on the soil forming processes. Poorly drained soils are relatively better drained so they have only a very thin layer of muck and peat, if any at all.
Map 8 shows Farmington’s significant wetland resources. A wetland is defined as a contiguous area of poorly or very poorly drained soils. Poorly drained soils occupy 11.6% of the community, and very poorly drained soils occupy 3.65%. Wetlands cover 17.58% of Farmington’s total land area. Table 3-1 below provides additional data related to Farmington’s wetland resources.
Table 3-1 Farmington Wetlands
Acres % of % of Wetland Predictor Type Town Wetlands
Very Poorly Drained (Hydric A) 863.4 3.7 % 20.8 %
Poorly Drained (Hydric B) 2757.4 11.7 % 66.3 %
National Wetlands Inventory Predicted 1267.6 5.4% 30.5 %
Total of areas of NWI and all Hydric soils (intersection) 732.3 3.1 % 17.6 %
Total of areas of Hydric or NWI-predicted wetlands 4156.1 17.6 % 100.00 %
(Total town land area = 23639.880 acres)
7.3 Prime Wetlands
The State of New Hampshire allows communities to designate “Prime Wetlands.” This designation means that the NH Wetlands Bureau, when receiving applications for dredging or filling wetlands, will apply an extra layer of rules defined by state law to applications involving wetlands designated by the town as “prime.” The first step in the designation process is an inventory and assessment of the town’s wetlands using the “NH Method.”
Natural Resources Chapter 3-12 Farmington Master Plan ~ 2005
Submitting wetlands to the NH Wetlands Bureau for Prime Wetland status requires preparing a map of the wetland area, a vote at a town meeting, and submitting a prime wetlands application to the NH Wetlands Bureau for approval. Farmington has no Prime Wetlands designated at this time, but the recent wetlands study conducted by Moose Mountains Regional Greenway contains all the mapping and support needed to file for Prime Wetlands designation.
7.4 Wetland Permitting
Projects which impact wetlands in Farmington are regulated by federal, state, and local regulations. The most comprehensive regulatory program is that of the NH Wetlands Bureau (NHWB). NH RSA 482-A authorizes the Department of Environmental Services (DES) to protect the State’s wetlands and surface waters by requiring a permit for dredging, filling or construction of structures in wetlands or other waters of the state. RSA-482-A and the rules promulgated under that law require that projects be designed to avoid and minimize impacts to wetlands and other state jurisdictional areas. The impacts that are proposed must be only those that are unavoidable. It is the responsibility of the applicant to document these considerations in the application for a permit.
According to DES rules, each project that requires a wetlands permit is classified in one of three categories according to the type and potential square footage impact of the project – minimum, minor, or major. Many projects qualify for processing with the Minimum Impact Expedited application which may include repair and maintenance of a dock, installation of a culvert for driveway access to a single family house, or maintenance dredging of an existing pond.
Another type of project common to New Hampshire is wetland impacts due to logging. These projects are permitted through a notification process that must be filed at the same time as the “Intent To Cut” forms provided the operation is conducted in accordance with the publication, “Best Management Practices for Erosion Control on Timber Harvesting Operations in New Hampshire.”
Historically, Farmington has had a poor record of wetland protection. Many wetlands have been illegally dredged for peat or to make topsoil, and others have been filled for construction or other land-uses incompatible with wet soils. These actions are slowly eroding the lands’ ability to filter toxins, support important wildlife, absorb high flood waters, and allow gradual recharging of underlying aquifers.
The Farmington Zoning Ordinance adopted March 13, 2001 contains a Wetlands Conservation Overlay District which is defined by three wetland classes that are based on certain criteria and review standards.
Class One, Two and Three wetlands are defined. The Zoning Ordinance empowers the conservation commission to redesignate any wetland with proper hearings.
