I. Rural Area Development Density – Reviewing Options & Norwich Model

Alex reviewed past efforts on rural development issues, noting a draft document with regulatory revisions dated June 2008, and also the review of other towns’ models including one developed for the Town of Norwich.  Alex introduced Brian Shupe, a consultant with the Vermont Natural Resources Council, who will be helping to investigate the Norwich model and what could be adapted for the town of Hinesburg.  They hope to put together several options for density models for review by the SB and community.

 

Brian said the Norwich regulations have been in force since August 2004, seem to be working as envisioned and are non-controversial.  He noted amendments in 2006 that gave natural resources even more attention.  He described the two basic steps of the Norwich model:  1) the calculation of “take-outs”, sensitive areas that do not count towards a parcel's density calculation; and 2) the review of 3 factors: road condition; proximity of development area to village growth center; continuity to conservation lands.  Alex said development pressures and the existing growth center in Norwich are different from Hinesburg's.  The group discussed those differences, including road configurations and local and regional traffic usage within and around town. 

 

The group discussed the classification of Hinesburg’s roads (class II, III, IV) and differences in character, usage and costs related to paved versus dirt roads.  Alex said it was difficult to generalize about maintenance costs by road type as it depended on various factors including grades and traffic volume.  He reviewed various road and population maps.  Road issues discussed in detail included:

-         Hinesburg’s “inter-town” traffic (non-residents traveling through Hinesburg’s center) as well as alternate routes used by Hinesburg residents that do not intersect with the center (such as travel to and from the heavily populated NE part of town).

-         The possibility of overdevelopment (frontage) on class II roads; Brian said feeder roads into subdivisions would be more likely to occur than frontage development.

-         Reasons other than maintenance costs to preserve dirt roads (recreational, their use by other forms of non-vehicular traffic)

-         Access from a dirt road to a paved road (i.e. which dirt road and where one lives on it affects the overall usage of dirt roads in Hinesburg).

-         Access to town services such as police, fire and emergency services

 

The group discussed whether a village proximity factor should be considered for a Hinesburg density model.  Brian explained that linear miles, rather than concentric circles, were used to determine proximity to the Norwich town center.  Alex described the two large rural zoning districts in Hinesburg – Agricultural and Rural Residential II.  He encouraged PC members to create a logical, understandable formula system that landowners can use to predict their density, rather than leaving it up to DRB review.  Charles Kogge, a member of the Conservation Commission, suggested that the PC develop a vision of what they want the rural areas to look like, then retrofit density formulas to that vision.

 

The group discussed proximity to conserved areas, considering these points:

 

-         How to assess development near conserved lands – should all lands be treated equally? Or only those with certain factors such as their status as a wildlife corridor or as one containing rare habitat?

-         Land is conserved for different reasons (from protecting fragile habitats to providing recreational opportunities).  Alex said access to a recreational area by a cluster of house would be viewed as desirable by those residents. 

-         Should conserved lands carry a “sphere of influence” that discouraged development close to its borders?  Brian Shupe said Norwich chose only two types of conserved lands – the Appalachian Trail corridor and a town forest parcel in which the town had wildlife preservation and water quality interests.  He said in doing so, Norwich hoped to avoid 1) discouraging residents from putting their land in conservation and 2) incenting others to conserve land to artificially control densities.

 

Bill Marks gave an update on the Greenspace plan being developed by the Conservation Commission.  He said there is a rationale for being more diligent about parcels adjacent to conserved lands.  Andrea questioned whether a better definition of the rural areas would be described differently from how it is currently stated in town regulations, which seems to assume that residential development is the highest and best use.  The group discussed the aspect of contiguity, particularly with forested lands, as being important, not to just look at individual parcels (public or private) but to look at the context.  Regional planning efforts regarding a wildlife corridor extending from Shelburne Pond to Bristol Pond were discussed.

 

The group had a lengthy discussion of whether to include “take-outs”, sensitive areas that do not count towards a parcel's density calculation, in a rural density formula. Bill Marks said take-outs can be offset with higher densities.  Tim liked the idea of lower densities in sensitive areas but was not as supportive of road calculations.  Will asked whether the newly-adopted village zoning should be linked (at least in conversation) to proposed rural zoning.  Joe I. said he did not think so, noting 1) public sensitivity to an “us and them” approach (some are allowed development rights and others are not); 2) reasons why person wish to subdivide (some to pass land on to children, other purely financial) and 3) a more densely-populated village makes nearby rural areas more attractive.  Ken Brown said where the Town Plan encourages an increase in village densities, it also encourages the preservation of the rural areas around it.  Joe I. said rural densities should be based on what we can do (looking at services and resources, for example) rather used as a way to offset village densities.  

 

Will asked if the CC could provide a prioritized list of take-out factors to consider, either general natural features (wetlands, forested areas) or specific (mapped) areas.  Alex said the PC could prioritize such a list but more importantly, they would have to decide whether to take those items “off the top” before any density calculation.  How to assess parcels equitably and accurately for sensitive areas and other site constraints (e.g. wetlands, steep grades) was discussed.  The use of design standards (e.g. clustering, setbacks, infrastructure) and how they help to naturally control densities was discussed.  Alex said our current regulations already require a critique of site constraints and design standards; the problem is that we do not clearly define the starting base densities.  He described this as the minimum lot size question, whether:

 

            # of allowed building lots  =  acreage ÷  minimum lot size for the district ?

 

Deborah Howard said she liked the idea of factoring road type into a density calculation but asked if this could be done without unintentionally incenting people to pave roads to allow for development.  Ken Brown said rising costs are making paved road types expensive to maintain as well.  Other concerns related to paved roads, such as safety and stormwater runoff, were discussed.

 

Members discussed what type of program would be best received by the public, for instance, one that incorporated incentives rather than take-outs; such a program may have to begin with artificially low densities.  Alex said he would make several options for easily understandable formulas, considering take-outs versus setting low base densities.  He would also run build-out scenarios for rural areas using those formulas.  Joe stressed a focus on critiquing the formulas, rather than resulting (imaginary) scenario numbers, at any public forum.  Tom said he agreed that regulations could restrict building in sensitive areas, but that people’s rights to develops should not be taken away.  He said a conserved land “sphere” should not impact neighbors.
