Introduction

A Limited Development Conservation Community.

Definition- A development that subdivides a parcel off into fewer lots than what zoning codes would permit while dedicating a portion of the property as permanent protected open space.

Why a Conservation Community versus Typical Development?

In growing metropolitan areas, cities and counties adopt planning and zoning or-dinances that have the purpose to allow for every acre of buildable land to be de-veloped. Developers take full advantage of these ordinances in order to maximize profit. Because of the drive for profit along with land use regulations and a limited model of how development should take place, soon every buildable acre of forest and countryside will be covered in suburbia and strip shopping centers in the name of “improvement.” Typical communities lack open space for recreation, and develop the land to the max resulting in decreased biodiversity and increased runoff from impervious surfaces. Without parks and open spaces, conventional neighborhoods miss out on social opportunities resulting in individuals living alone instead of in community.

What is a Limited Development Conservation Community?

A SHIFT IN THINKING

CONSERVATION IS...........

FROM THIS -------------------->>>>> TO THIS

Introduction

The traditional school of thought for developing subdivisions is to maximize profits by maximizing the number of lots that can be fit onto a parcel of land. The shift occurs with the realization that a conservation community offers a higher quality of life and community.

Shiftingthought

Page 4: Sam Wirth - Senior Terminal Project

Typical characteristics of a Conservation Community- - Common open spaces - 40% or more of total = Open Space - Clustered compact lots - Typically 40 parcels or larger - Parcel is not developed to hold maximum allowed by zoning - Conservation of usable farm land - Conservation of hardwood forests - Conservation of streams - Conservation of wildlife habitat - Walking and hiking trails - Educational opportunity

Benefits of a Limited Development Conservation Subdivision

- Provides a quality residential and recreational environment - Consolidation of infrastructure - Reduced development costs - Higher home values - Open space as an amenity - Conservation of wildlife habitat - Protected water quality - Conservation of local farm land - Reduced demand for public funded green space - Means for expanding public trails and greenways - Reduced maintenance costs - Social opportunity

Page 5: Sam Wirth - Senior Terminal Project

There are many communities and organizations that promote the growth and develop-ment of conservation subdivisions and green communities. Three Oaks builds upon these existing concepts and improves upon them. Three Oaks most closely resembles the Green Way Cottage Community located near historic Lexington, Virginia. The Gre-enway Community offers rural living a few minutes outside of town, similar to the Three Oaks Conservation Community. Many of the covenants were derived from the covenants of the GreenWay community.

The Three Oaks Design Objectives -

Three Oaks is a conservation community that encourages sustainable living, community interaction and education for future generations.

Three Oaks blends land for food production, smaller lots, green building, and open space for recreation, pasture and wildlife habitat preservation.

Three Oaks provides land community land for locally grown produce and a retail area with a farmers market for the resale of local food products.

Three Oaks is designed to be family friendly, and allow for maximum open space for out-door activities and education on local food production.

Every residential lot in Three Oaks is backed by community owned greenspace and walk-ing trail and every lot fronts on open pasture and field for community use for agriculture and recreation.

Three Oaks combines the comforts and amenities of living in community with a rural farmhouse environment.

“Let us ask the land where are the bestsites. Let us establish criteria formany different types of excellenceresponding to a wide range of choice”

- Ian McHarg

The process used to design the Three Oaks Community hinges directly upon the in-ventory and analysis process pioneered by Ian McHarg in which different analysis maps are created and overlaid to define the best buildable areas and locations.

The vegetation inventory and analysis revealed that areas more recently farmed and developed were being taken back by early successional plants like broomsedge and young pine. Other parts of the site, have later native tree species such as oak, hickory, and poplar. There are large groves of small pine about 20’ tall and under 5” in diam-eter. These pines are not seen as a limiting factor.

The composite analysis map makes use of Ian Mcharg’s overlay method and takes the slope, vegetation and hydrology maps and overlays them. The process was to take the fac-tors that were more limiting such as steep slopes, and flood planes and make them darker colors, while factors that were less limiting such as young pine were lighter gray. These maps were make transparent and overlaid. The darker areas on the map show more limi-tations while the whiter areas show little or no limitation on development.

This section shows two- two story homes. One at the top of the hill and one down hill towards the bottom of the site. This section illustrates that the home at the top of the hill blocks views onto the site from Campground Rd., and limits the views uphill from residences located towards the bottom of the hill.

This section shows that locating residences towards the back of the site, down hill from campground keeps an uninhibited view uphill from the homes and preserves the view from Campground Rd. allowing for the illusion of an undeveloped site.

Concept10

Concept 10 has some major drawbacks like the retail area on lightly traveled Bentley Rd. so it would not receive as much exposure to potential clients. The site circulation is proposed to cross a wet weather streambed which would also require additional grading. For the lot lay out, there are lot clus-ters on the top of the hill which limit and break up views.

Concept 9 has some advantages but some major drawbacks as well. The advantages of concept 9 include the retail area being located on heavily traveled campground road. The retail area takes advantage of the location and beauty of the three oaks. Also, the amenities are in a good location on a open ridge. The drawbacks are that the site circulation crosses a wet weather streambed. The lot locations also pose a problem because, once built, the homes will limit views.

Concept 8 has more drawbacks than advantages. The advantage is the retail space being lo-cated near the corner of Bentley and Campground Rd. However the drawbacks involve the stream crossing, the lot location on the hill and the fact that the retail area would be built on land that could otherwise be used for agriculture land.

Concept 7 has the retail space back near the three oaks on campground road, however, the concept also involved developing within the conservation area on the southern portion of the site. Though the area proposed for lots is not a high limitation area, a road would need to be cut through the conservation area in order to reach those lots.

Concept 3 has many advantages. The location of the retail space on campground road allows for open space near the three oaks and the circulation and development pattern is good. The draw back to concept 3 is the circulation pattern at the north side of the site. Dead end circu-lation limits the number of home sites that the north part of the site could accommodate.

The concepts and sketches of the retail area explore different placements of the build-ings and parking lot. The goal was for minimum site disturbance, maximum street exposure, and good circulation for both vehicular and pedestrian traffic. Concepts 1, 2, and 3 did not allow for a good relationship between vehicular and pedestrian circu-lation. Concept 5 did not allow for the buildings to have road frontage and ended up being more of a traditional retail space with the parking in front. Concept 4 ended up being the best concept with parking available for both the Farmers Market and General Store. Concept 4 also had the least amount of site disturbance.

Retailareaplan

The final retail area plan was developed after the concepts by using development standards for parking spaces and 35’ turning radius on the turns. On the East side of the site, the roll-off recycling dumpsters are located in such a way so that the trucks can enter off of campground and go with the flow of traffic in the parking lot, and then back in to pick up the dumpsters. Similarly, the trash dumpsters are situated so a trash truck and front in and empty the dumpsters. The parking lot has a storm wa-ter infiltration area in the middle. The parking lot is graded at 2% all around so that storm water drains in the storm water infiltration area. There are 2 handicap spots on the Farmers market side of the parking lot and the General Store side.

Retail Area Sign Concept

The retail sign was designed to depict the character of the Three Oaks Community. The sign would be weather wood 6”x6”” posts on 2’ tall historic brick pillars. 2” x 12” boards would announce the Three Oaks General Store, Farmers Market and Recycling Center. The sign is covered by a tin roof, which reflects the roof material found on all buildings throughout Three Oaks.

These drawings show the grading plan and spot elevations for the parking lot and structures of the Three Oaks retail area. Inside the parking lot curbs, the water flows into the storm water infiltra-tion area. A 12” over flow drain is located to prevent water from ponding in the parking stalls in the event of a large rainstorm. Outside of the parking curbs, water is directed away from the building using grass swales.

Roughgradingplan

Amenities

This is an approximate rough grading plan for the pool, tennis courts, parking lot, and clubhouse. The site was grades so a ridge would redirect water coming down hill from the site away from the clubhouse and into a swale that leads to the pond. Cuts in the parking lot curb would allow water to pass through. This drawing also shows that a retaining wall would be needed between the clubhouse and tennis court. The wall would be six feet tall and allow for a nice observation area for the tennis courts.

ArchitecturalStyle

These images show the architectural style that the homes in the Three Oaks Community. All homes would be required to have metal roofing, in order to be compatible for rainwater harvesting systems. All home designs should feature a large covered porch for the enjoyment of the resident. No garage or parking spaces should be visible from the curb. It is preferred that homes meet Earth-Craft or LEED for homes standards. Siding and trim colors should be earth toned while roof colors may vary but must be chosen from the Englert metal roofing color pallet.

ArchitecturalStandards

All structures in the Three Oaks Com-munity are constructed with metal roofs and rain water harvesting systems. Metal roofs are more environmentally friendly and allow for use of rainwater harvesting systems. Traditional asphalt roofs shed pollutants and debris while metal roofs allow for the capture of clean water and no pollutants. Metal roofs have been approved by Energy Star and LEED as energy efficient and a “green” alternative to traditional roof-ing. The color pallet to the right is a pal-let that maybe used in the Three Oaks Community. Certified metal roofs are also eligible for tax credits.

RainWaterharvesting

ThreeOaksCommunity

The Ultra 1700 RHS is a 1,700-gallon capacity rainwater harvesting system with a below ground, polyethylene tank and is designed for non-potable water uses including home landscaping and irrigation, vehicle cleaning, household toilet flushing and launder-ing. The Ultra comes with a downspout basket filter to prevent debris from entering the chamber. The unit also features a calmed inlet which prevents the disturbance and re-suspension of fine sediments that gather on the bottom of the tank. The inlet also intro-duces oxygen into the lower layers of the tank which maintains a fresh supply of water while preventing anaerobic conditions from forming. The Ultra 1700 RHS also has an automatic pumping system and accessory fittings which can be installed in two days by two to three installers. Options include a level indicator, rain tank infiltration block and faux rock cover for the pump.

CommunityGARDENPLOTS

ThreeOaksCommunity

The Three Oaks Community has three open spaces that can be used as com-munity garden plots. The location of the plots can rotate throughout the space over the years. Each year, the homeowners association can sub-divide the designated area for those homeowners interested in producing local produce for personal consump-tion or to sell at the farmers market located in the retail area.

There shall be a ten (10) foot wide right-of-way/easement along the perimeter bound-ary of the subdivision for use as walking trails. These rights-of-ways and easements are intended for use as common travel trails for Lot Owners, residents and their guests, and to encourage preserving and experiencing the natural environment throughout The Three Oaks Community.

Any property Owner failing to contribute his or her prorata share of the cost of main-tenance can be charged by the Home Owners Association for their proper share. Such charge, along with the cost of collection, including attorney’s fees, may be collected by any legal process available for the collection of debts, including foreclosure and the en-forcement of liens.

Water is one of our most valuable resources. Water conservation is encouraged by all residents and lot owners including rain water harvesting from roofs, rain gardens, wa-ter retention landscaping, and water saving appliances and fixtures.

In the spirit of community food self-sufficiency, with oversight by the Home Owner’s Association, residents may utilize the common land to raise produce including, honey bees, vegetables, fruits, nuts and herbs.

In order to minimize light pollution and allow all residence to have an uninterrupted view of the night sky, no pole light, dusk to dawn lights or overhead outdoor lighting will be allowed. Acceptable outdoor lightning will be limited to motion sensor lighting or manually controlled lighting not to exceed 150 watts per lamp and six feet in height. All outdoor lighting must be approved by the architectural review committee prior to construction.

No use or discharge of toxic chemicals, insecticides or other poisons will be permitted on or in the land, air or waters, including ground water. “Natural predators” and certi-fied “organic” methods of pest and weed control may be used.
