Lot 1 and 11 are two existing corner lots with primary frontage on an internal private street, but are adjacent to Park Road, a public street. The area of open space between Lot 1 and 11 is an ideal opportunity for the creation of five affordable lots. The manufactured home park is already visible from Park Road and the addition of five lots on Park Road would not create substantial impact. d. The minimum distance between manufactured Lot 8-11, 18-29, 32-65, 67-71 (total 55 lots) Lot 5N homes shall be 30 feet. The Albemarle County Fire Marshal may require additional space between manufactured manufactured homes if public water is not available There are 55 existing structures that do not have 30' of separation on all sides. The structure on Lot 5N is approximately 21' from the existing structure on Lot inadequate for fire protection. 11.

Lots 67-73 contain structures that are very close to the adjacent property, with the existing structure on lot 67 located 1.1' from the property line with tax map parcel 56-51. The location of these structures are pre-existing and would not create an additional detriment on the neighboring parcel. Lots 12-17 are adjacent to the Westhall subdivision, constructed in 2008. The location of these structures are pre-existing to the creation of the adjacent subdivision and would not create an additional detriment on the neighboring parcel. Furthermore, both the subject property and the adjacent Westhall subdivision are zoned R-6; where a conventional R-6 development is required to maintain a 20' rear setback, the 50' setback would require 70' of separation between two structures of the same zoning. 70' of separation is not warranted between two R-6 communities. c.

Requiring nearly 2,800 LF of existing private roads to be improved these standards would significantly increase construction costs for an existing Notes property that provides affordable housing for 73 households, as well as requiring several structures to be moved; moving a manufactured home can cost thousands of dollar per unit. Where the median mortgage in Crozet is $432,6001, household incomes would need to be well over $100,000, excluding additional costs such as property taxes and insurance. As these estimates are from 2020, the median mortgage is to have likely increased in 2022. Substantial construction costs for a property with an established affordable housing community would further exclude households that continue to be priced out of Crozet, as well as the County. While non -single-family detached housing is steadily emerging in Crozet, many households greatly value the community, yard space, and privacy that a manufactured home park can provide. Much of the community includes retired neighbors and many of the residents have lived within the park for at least a few years. 52506 Financial Characteristics for Housing Units with a Mortgage, U.S. Census Bureau, 2020 American Community Survey 5-Year Estimates S H I M P ENGINEERING, P.C.

The existing turnaround at the end of Adele Street has approximately a 25' radius. 3g. Minimum radius of edge of pavement is 25 feet. Intersection of Agatha Street and Adele Street No new streets proposed Nearly all radii of existing edge of pavement is 25' or more. However, at the intersection of Agatha Street and Adele Street, the radius does not meet 25' However, based on the existing road network, few vehicular trips would make the right -turn maneuver from Agatha Street to Adele Street. Very few vehicles would approach the site westbound on Park Road. Vehicles traveling from Route 250 and Interstate 64 would access the site eastbound on Park Road. To reach their homes on Adele Street, residents would travel eastbound on Park Road and take the first left turn onto Adele Street. 3h.

Sec. 5.3.8 c. Recreation requirements. See section 4.16 Recreational equipment per Sec. 4.16 is not currently present on the property. Recreational equipment per Sec. 4.16 is not proposed. Improvements Per Sec. 4.16, 73 units would require two tot lots within a 4,000 sq. ft. fenced -in required - area. The manufactured home park is located on Park Road and is approximately 1000' east of the Claudius Crozet Park entrance. For pedestrian access, the subject Manufactured home park property is immediately adjacent to the Jonna Street public ROW, which intersects with the Eastern Avenue public ROW. From Eastern Avenue, there is a public access trail easement through Glenbrook's stormwater forest and open space easement lot, which provides direct access to the rear of Claudius Crozet Park. d. Pedestrian access. The requirements of section All existing streets (Adele Street, Claudia Street, Alfred Street, Agatha Street) No new streets proposed 32.7.2.3 shall be met. Sec. 32.7.2.3 of the Albemarle County Zoning Ordinance states that the agent may require sidewalks on one or both sides of the street. The agent may require additional sidewalks or pedestrian walkways between buildings, to adjacent properties, and, where appropriate, to private areas of recreation and open space, and to offsite public areas of recreation and open space. Per Sec. 32.7.2.3, it is in the agent's discretion to determine whether sidewalks would be required on the property. As an established manufactured home park, the community has adequately facilitated pedestrian movement throughout the property without sidewalks for over 40 years. Due to the existing geometry of the private streets without separate pedestrian infrastructure, vehicles travel at significantly lower speeds upon entering the property and anticipate pedestrians within the shared space of the street. Furthermore, the private streets do not provide interparcel connectivityand vehicles traveling on these roads are slowing down to find a parking space. g. Landscaping and screening. The requirements of All existing lots All proposed lots section 32.7.9 shall be met. In addition, screening may be required in accordance with section 32.7.9.7 around the entire perimeter of the park, or part Screeningaround the perimeter of the ark is not resent and is not proposed with the special use permit. The roe is surrounded b R-4 Residential, R-6 P P P P P P P property rtY y thereof, except where adequate vegetation already Residential, and Planned Residential Development; there is an R-2 Residential development across Park Road. Sec. 3.7.9.7 -Screening of the Albemarle County exists and a conservation plan has been submitted in Zoning Ordinance describes that such landscaping is required in screening commercial and industrial development from rural areas, in screening parking areas accordance with section 32.7.9.4(b). from residential and rural areas, features that may have negative visual impacts (loading areas, refuse areas, storage yards, detention ponds, and recreational facilities), double frontage lots, and where historic properties may be impacted. As an existing manufactured home park that was established well before the development of the surrounding properties, screening of this existing community is not warranted. The manufactured home park is an existing residential development within a residential area. The existing density of the park is 5 DUA and the addition of 14 lots would bring the density to 6 DUA; where a zoning map amendment to a dissimilar zoning or a special use permit for a more intense use may necessitate screening, this proposal seeks to bring an existing use in conformance, with a proposed density within the existing zoning parameters.
