AGENDA DATE: October 14, 2009 ACTION: X INFORMATION: CONSENT AGENDA: ACTION: INFORMATION: ATTACHMENTS: Yes STAFF CONTACT(S): REVIEWED BY: Messrs. Tucker, Foley, Davis, Kamptner, Graham, and Fritz; and Ms. McCulley LEGAL REVIEW: Yes BACKGROUND: On November 12, 2008, the Board held a public hearing on this proposed subdivision ordinance text amendment, which would amend County Code § 14-404 to reduce the number of entrances allowed onto public roads, amend County Code § 14-412 to change the road standards for private roads serving 2 -lot and 3 to 5 -lot subdivisions, and amend the applicable requirements for Rural Subdivisions by making the requirements of Section 14-404 applicable to them. At the close of the public hearing, the Board directed staff to work with the community to identify concerns and alternatives. On February 26, 2009, staff conducted a Roundtable discussion. On June 3, 2009 the Board held a worksession to discuss the options identified at the Roundtable. The Board directed staff to prepare an ordinance that would apply only to certain streets and to develop administrative waiver criteria. The Board also directed staff to amend the private street standards so that they were consistent with the driveway standards found in the Zoning Ordinance. STRATEGIC PLAN: Goal 1: Enhance Quality of Life for all Citizens Goal 4: Effectively Manage Growth & Development Adoption of regulations designed to improve emergency access (street standard) and minimizes entrances (single point of access) can promote these goals. DISCUSSION: The proposed ordinance would amend the Subdivision Ordinance to reflect the June 3, 2009 directions from the Board. Some of the key components of the proposed ordinance are outlined below. Single Point of Access Applying single point of access requirements only to certain roads The proposed ordinance would require single points of access on Major Rural Streets if the frontage of any proposed lot is less than 500 feet. Major Rural Streets include those roads with more than 1,400 vehicle trips per day (vtpd) with two exceptions. Generally, streets of over 1,400 vtpd are considered collector streets intended for mobility. Streets of less than 1,400 vtpd are considered local streets intended for accessibility. Greater regulation of entrances on the higher volume roadways serves to protect the traveling public and preserve the primary purpose of those streets which is mobility. Some streets with less than 1,400 vtpd have been identified as Major Rural Streets. These include Irish Road (Route 6) and Old Ballard Road. Irish Road was added because it is a Primary Road with approximately 1,200 vtpd. Old Ballard Road (Route 677) was added at the request of the Board to reflect the volume of traffic on the road combined with the level of development on the road and the geometrics of the road. However, the number of entrances on streets with lower traffic volumes will not be restricted by the proposed ordinance and will continue to be able to have more points of access than those subdivisions on major rural streets. The proposed ordinance also would relocate from subsection 14-404(8) to subsection 14-404(A) the current access requirements applicable to a subdivision lot that is later subdivided itself. This requirement is amended to clarify that the access requirements apply to any lot, rather than just the residue, of the original subdivision. Waivers A clear desire was stated by the participants at the Roundtable discussion to include administrative waiver provisions. The proposed ordinance authorizes administrative waivers for all waivers pertaining to single points of access. The factors that would be considered to waive the single point of access requirement include: whether installing a single point of access would substantially impact environmental resources such as streams, stream buffers, critical slopes, and floodplain; whether construction of a single point of access would substantially impact features existing on the property prior to October 14, 2009; whether granting the waiver would contribute to maintaining an agricultural or forestal use of the property; and whether granting the waiver would facilitate development of areas identified in the open space plan as containing significant resources. Private road standards The proposed ordinance would: • Make private roads serving 2 -lot subdivisions subject to the same design standards as for a driveway as provided in Zoning Ordinance § 4.6.6. • Apply the clearance and maximum grade requirements for a driveway as provided in Zoning Ordinance § 4.6.6 to subdivisions of 3 to 5 lots. • Specify that a road's grade is measured over a distance of 50 feet. • Establish administrative waiver procedures and criteria for all road standard design requirements. BUDGET IMPACT: Administration of the proposed ordinance will require additional staff time to evaluate entrance conditions, 2 lot private road standards, and process waiver requests. However, the increase is considered minimal and no additional funding or staffing will be needed. RECOMMENDATIONS: After conducting a public hearing, staff recommends adoption of the attached ordinance.

On -Site Improvements and Design Sec. 14-404 Lot location to allow access from lot onto street or shared driveway. Each lot within a subdivision shall be located as follows: A. Single point of access required. Each lot, other than a corner lot within the development areas, shall have reasonable access to the building site from only one street, shared driveway or alley established at the same time as the subdivision;. B. provided that Conditions when single point of access not required. Notwithstanding subsection (A), a lot may be located so that its driveway enters only onto a public street abutting the subdivision if: (i) the commission grants agent approves a waiver under subsection (C); (ii) the subdivider obtains an entrance permit from the Virginia Department of Transportation for the access; (iii) the entrance complies with the design standards set forth in sections 14-410(F) and 14-410(G); and (iv) the subdivider demonstrates to the agent prior to approval of the final plat that the waiver does not violate any covenants to be recorded for the subdivision. For purposes of this section, the term "reasonable access" means a location for a driveway or, if a driveway location is not provided, a location for a suitable foot path from the parking spaces required by the zoning ordinance to the building site; the term "within the subdivision" means within the exterior boundary lines of the lands being divided. Draft: 09/21/09 3 B. If the subdivision is within the rural areas, all subsequent divisions of the residue shall enter only onto such street(s) shown on the approved final plat and shall have no immediate access onto to any public street. C. Standards for waiver. The requirements of this section subsection (A) may be waived by the commission agent as provided in section 14-225.1 14-224.1. In reviewing a waiver request, the commission shall determine whether: (i) the county engineer recommends an alternative standard; or (ii) because of unusual size, topography, shape of the property, location of the property or other unusual conditions, excluding the proprietary interests of the subdivider, strict application of the applicable requirements would result in significant degradation of the property or to the land adjacent thereto. In approving a waiver, the commission shall find that requiring the standard would not forward the purposes of this chapter or otherwise serve the public interest; and granting the waiver would not be detrimental to the public health, safety or welfare, to the orderly development of the area, to sound engineering practices, and to the land adjacent thereto. In reviewing a waiver request, the commission may allow a substitute design of comparable quality, but differing from that required, if it finds that the subdivider would achieve results which substantially satisfy the overall purposes of this chapter in a manner equal to or exceeding the desired effects of the requirement. A request for a waiver may be made prior to or with submittal of a preliminary or final plat, as follows: 1. Information to be submitted. A request shall include a justification for the waiver and a conceptual plan. The conceptual plan shall: (i) be drawn at a scale no smaller than one (1) inch equals two hundred (200) feet showing surveyed boundaries of the property or an alternative scale approved by the agent; (ii) show the topography of the property at the best interval available from the County including delineation of proposed building sites; (iii) show the locations of streams, stream buffers, critical slopes, floodplains, and known wetlands; and (v) show the proposed layout of lots, location of existing features such as buildings, fences, drainfields, existing driveways or other access ways, or other significant features. 2. Consideration and findings. In reviewing a waiver request, the agent shall consider whether: (i) installing a single point of access would substantially impact environmental resources such as streams, stream buffers, critical slopes, and floodplain; (ii) construction of a single point of access would substantially impact features existing on the property prior to October 14, 2009; (iii) granting the waiver would contribute to maintaining an agricultural or forestal use of the property; and (iv) granting the waiver would facilitate development of areas identified in the open space plan as containing significant resources. In approving a waiver, the agent shall find that requiring the extension would not forward the purposes of this chapter or otherwise serve the public interest; and granting the waiver would not be detrimental to the public health, safety or welfare, to the orderly development of the area, to sound engineering practices, and to the land adjacent thereto. D. Terms defined. For purposes of this section, the term "reasonable access" means a location for a driveway or, if a driveway location is not provided, a location for a suitable foot path from the parking spaces required by the zoning ordinance to the building site; the term "within the subdivision" means within the exterior boundary lines of the lands being divided.

(b) Private streets in the development areas. For such private streets in the development areas, the agent may approve Virginia Department of Transportation standards for mountainous terrain or an alternative standard deemed adequate by the county engineer to be equivalent to or greater than the applicable standard in the design standards manual, so as to adequately protect the public health, safety or welfare. Draft: 09/21/09 5 4. Streets serving family or two -lot subdivisions. Each private street authorized to serve a family subdivision under section 14-232(B)(1) or a two -lot subdivision under section 14-232(B)(2) shall satisfy the following: (i) easement or right-of-way widths shall be ten (10) feet minimum; and (ii) the surveyor shall include the following wording on the plat: "The existing and/or proposed right-of-way is of adequate width and horizontal and vertical alignment to accommodate a travelway passable by ordinary passenger vehicles in all but temporary extreme weather conditions, together with area adequate for maintenance of the travelway, as required by section 14-412 of the Albemarle County Code." B. Private streets serving non-residential, non-agricultural, attached residential, multi -unit residential and combined residential and non-residential uses.

The agent may require minimum travelway widths to provide for on - street parking upon a determination that the provisions for off-street parking may be inadequate to reasonably preclude unauthorized on -street parking. C. Clearing land for improvements. A private street constructed to Virginia Department of Transportation standards shall not be subject to that department's clear zone requirements. D. Landscaping and other improvements permitted. Subsequent to construction of a private street, a subdivider may install ornamental plantings and any other improvements provided that they do not conflict with sight distance, drainage facilities or other required improvements. E. Waiver. The requirements standards of sections 14-412(A)(1)(i) and 14-412(A)(2)(a) relating to street easement or right-of-way widths may be waived by the commission agent as provided in section 14- 225.1 14-224.1, as follows: . 1. Waiver of section 14-412(A)(1)(i). The agent, with the recommendation of the county engineer and the fire marshal, may waive the standard in section 14-412(A)(1)(i) and authorize a street having a grade that exceeds sixteen (16) percent if the subdivider demonstrates to the satisfaction of the county engineer and the fire marshal that public safety vehicles would be able to access each lot even though the grade may exceed sixteen (16) percent. In developing their recommendation to the agent, the county engineer and the fire marshal shall consider: (i) the length of the segment of the street that would exceed sixteen (16) percent; and (ii) whether the segment that would exceed sixteen (16) percent would require the public safety vehicle to travel uphill towards each lot. In authorizing such a grade, the agent may impose reasonable conditions to assure that the public safety vehicles may access the lot including, but not limited to, a condition limiting the maximum length any segment of the driveway may exceed sixteen (16) percent. 2. Waiver of section 14-412(A)(2)(a). In reviewing a waiver request for a lesser street easement or right-of-way width under section 14-412(A)(2)(a), the commission agent shall consider whether: (i) the subdivision will be served by an existing easement or right-of-way of fixed width that cannot be widened by the subdivider after documented good faith effort to acquire additional width; and (ii) the existing easement or right-of-way width is adequate to accommodate the required travelway and its maintenance. If the waiver pertains to minimum street easement or right-of-way widths over an existing bridge, dam or other structure, the commission agent shall consider whether: (i) the long-term environmental impacts resulting from not widening the bridge, dam or other structure outweigh complying with the minimum width requirements, as determined by the county engineer; or (ii) whether the bridge, dam or other structure is a historical structure. In approving a waiver, the commission agent shall find that requiring the standard street easement or right-of-way widths would not forward the purposes of this chapter or otherwise serve the public interest; and granting the waiver would not be detrimental to the public health, safety or welfare, to the orderly development of the area, to sound engineering practices, and to the land adjacent thereto. Draft: 09/21/09 6 G. Eligibility for future acceptance into the system of state highways. Any and all streets that are not constructed to meet the standards necessary for inclusion in the system of state highways shall be privately maintained and shall not be eligible for acceptance into the system of state highways unless improved to current Virginia Department of Transportation standards with funds other than those appropriated by the General Assembly and allocated by the Commonwealth Transportation Board.
