LOCATION AND DEMOGRAPHY
Monticello Motor Club members are individuals and families passionate about motorsports, as well as people who attend private events for corporations, charities, auto manufacturers, and other large organizations. They frequently visit the area from mid-April through mid-November, and also during the winter.
Local government and communities are crucial participants in the many possibilities of socio-economic development. They need to ensure the availability of mixed-use spaces related to Lake San Joseph that are inclusive and connected to the broader population. Without such inclusive spaces, there is a risk of creating enclaves that cater only to specific groups, which can lead to social fragmentation and limit the overall potential for community growth and cohesion.
Second Home users are individuals from New York City and its surroundings who seek a rejuvenating nature experience and a place to unwind. They need a second home because urban life can be incredibly stressful. Escaping to a serene, natural environment provides them with much-needed relaxation and a chance to recharge, enhancing their overall well-being and quality of life.
Hasidic Jews are a branch of Orthodox Judaism, who adhere to a strict interpretation of Jewish law and traditions. They are interested in purchasing Saint Joseph’s Lake to extend their close-knit community. This acquisition would provide them with direct access to the lake, which is important for both recreational and ritual purposes, and it would also create a connection to Lost Lake. This expansion is seen as a way to enhance their communal lifestyle by offering additional resources and space for their growing population.

REGION SUMMARY: VISITOR SPENDING BY REGION
New York State is divided into 11 economic regions.
Visitor spending grew markedly in each region as travel confidence rebounded. New York City was the largest tourism region in 2022 (60% of state-wide spending) and saw the largest increase in visitor spending as travelers returned to cities.
REGIONAL DETAIL: CATSKILLS
In 2022, visitor spending and tourism-related employment grew to $2.3 billion and 17,306 jobs, respectively. Visitor spending in the Catskills increased by 19% to reach 146% of 2019 levels, highlighting visitors’ continued preference for outdoor and rural vacation destinations. Relative to 2019, traveler spending was up most in Sullivan County at 154% of 2019 levels.

INVASIVE SPECIES IN NEW YORK STATE
Zebra mussels are an invasive species that threatens U.S. waters. It is a fingernail-sized mollusk that is native to fresh waters in Eurasia. Their name comes from the dark, zig-zagged stripes on each shell.
INVASIVE SPECIES IN NEW YORK STATE
MACRO ANALYSIS
LEAFY SPURGE
Leafy spurge is an invasive Eurasian perennial introduced into the United States as a contaminant of crop seed in the 1880s and 1890s. It is an invasive plant that is poisonous to cattle and infests more than 2.7 million acres in southern Canada and the northern Great Plains. It typically forms monocultures and because of the latex that occurs in all parts of the plant, it is not consumed by naturally occurring herbivores. Leafy spurge is rapidly spreading and outcompetes native prairie and pasture plants, reducing wildlife habitat. USGS is using a variety of technologies to detect and map Leafy spurge infestations and is providing information on the effectiveness of various control methods.
INVASIVE SPECIES IN NEW YORK STATE
MACRO ANALYSIS
PURPLE LOOFSTRIFE
Purple loofstrife is native to Europe, Asia and northern Africa, with a range that extends from Britain to Japan. Purple loosestrife was probably introduced multiple times to North America, both as a contaminant in ship ballast and as an herbal remedy.
It is competitive and can rapidly displace native species if allowed to establish. Once established, the prolific seed production and dense canopy of purple loosestrife suppresses growth and regeneration of native plant communities. Monotypic stands of purple loosestrife may inhibit nesting by native waterfowl and other birds. Other aquatic wildlife, such as amphibians and turtles, may be similarly affected. The dense roots and stems trap sediments, raising the water table and reducing open waterways, which in turn may diminish the value of managed wetlands and impede water flow.

NEW YORK STATE ECOREGION: HIGH ALLEGHENY PLATEAU
MACRO ANALYSIS
HIGH ALLEGHENY PLATEAU
The High Allegheny Plateau Ecoregion (HAL) is located along the southern tier of New York and the northern tier of Pennsylvania. It includes a small portion of New Jersey. Well known features in HAL include the Catskills, The Shawangunks, The Kittatinny Ridge, The Poconos, Allegany State Park, Allegheny National Forest, and a large mass of Pennsylvania stateowned land.
The ecoregion is defined by high elevation features at the northern end of the Appalachian Plateau. Most of the ecoregion is above 1,200 feet. The general land form of the area is mid-elevation hills separated by numerous narrow stream-cut valleys.
One of the main features of the ecoregion is an abundance of rivers and streams. The Delaware, Susquehanna, and Allegheny Rivers and their many tributaries cover the entire ecoregion. The Delaware River drains into Delaware Bay; the Susquehanna flows into the Chesapeake Bay; the Allegheny flows into the Ohio and eventually into the Mississippi. These three different drainages contribute to the high overall aquatic diversity in the ecoregion.
GEOLOGY IN NEW YORK STATE
DEVONIAN PERIOD
Devonian Period, in geologic time, is an interval of the Paleozoic Era that follows the Silurian Period and precedes the Carboniferous Period, spanning between about 419.2 million and 358.9 million years ago.
The Devonian Period is sometimes called the “Age of Fishes” because of the diverse, abundant, and, in some cases, bizarre types of these creatures that swam Devonian seas. Forests and the coiled shellbearing marine organisms known as ammonites first appeared early in the Devonian. Late in the period the first four-legged amphibians appeared, indicating the colonization of land by vertebrates.
RELIGION IN NEW YORK STATE
MACRO ANALYSIS RELIGION
The following map represents the three main monotheistic religions in the state of New York, which are Christianity, Judaism, and Islam. Their locations are shown in general terms, with the information extracted from the OSM QGIS plugin data layers.
OSM Place Search is a plugin for QGIS that uses the Nominatim service to find addresses and places. The tool is still labeled as “experimental” plugin, so users should anticipate potential inconsistencies.
For this reason,the main religious points in the map are shared by the three monotheistic religions. This map aids in understanding the general geographic distribution and significance of these religions within our community, given their substantial influence.
SITE ANALYSIS
WATER RUN OFF
MAPPING/LOCATION/SITE
The natural terrain channels runoff flow towards the property’s edges, taking advantage of the slope in its favor. This creates an optimal central space for the house’s location.
The runoff flows towards the lake, predominantly in the eastern and western areas of the property, where the slope is gentler.
In the northern sector, where the mangrove is located, the runoff is lighter due to the slope and the relationship between the water and the land.
In the southern part of the property is the highest point, from which the slope directs more forcefully towards the western sector of the site.
MAPPING/LOCATION/SITE ANALYSIS
The following diagram details the annual movement of the sun on the terrain, guiding the orientation of the house to optimize views and promote an efficient design that maximizes natural light.
MAPPING/LOCATION/SITE ANALYSIS
The following chart shows the prevailing wind direction, which comes from the southwest and moves northeastward. This information guides the arrangement of the house to take advantage of natural ventilation.
MAPPING/LOCATION/SITE ANALYSIS
The presence of vegetation in the environment not only influences the ideal location of the house in relation to the terrain’s topography but also directs the dwelling towards the most prominent visual elements, such as the ocean and the lush mountain vegetation that surrounds it.
