The current application has been submitted to convert a 1250ft portion of Willis Drive from the full 36ft wide curb - and- gutter section to a private ditch - and - shoulder roadway. Because the site is located in the development area, a waiver of curb - and - gutter granted by the Planning Commission is required. And, although the roadway could be administratively approved by the Chief of Current Development under 14- 233.13.1, it is my opinion that the private road must be authorized by the Planning Commission because of 14- 234.C.4. The engineering analysis of the requests is as follows: Waiver of the requirement for curb - and - gutter: The applicant has requested a waiver of the construction of curb - and - gutter for the road design in accordance to County Code Section 14 -4101. The applicant would prefer the rural section, private roadway to remain in place until the medical office building north of the road is proposed (owned by the University of Virginia Foundation) or when traffic demand warrants the full road section. It is unclear what warrants the hospital would use to analyze this since the VDOT Road Design Manual does not provide much assistance on this issue; the VDOT Manual allows for both curb - and - gutter and ditch - and - shoulder sections for local urban streets. In the applicant's letter, no arguments were provided to be considered by the Planning Commission as to how granting the waiver would "not be detrimental to the public health, safety or welfare, to orderly development of the area, to sound engineering practices, and to land adjacent thereto" or better forwards the purposes of the Subdivision Ordinance. 14-410.i.2 Consideration and findings — In reviewing a waiver request to allow a rual cross - section (no curb and gutter) instead, the commission shall consider: (i) the number of lots in the subdivision and the types of lots to be served; This road would carry traffic from the surrounding medical offices and the hospital. The estimated traffic provided by the applicant for this portion of the roadway is between 3,600 and 6,800 vehicles per day. (ii) the length of the street; The proposed length of the rural section is approximately 1250ft. (iii) whether the proposed street connects into an existing system of streets constructed to a rural cross - section; Willis Drive from Peter Jefferson Parkway to the main hospital entrance is an urban section. State Farm Blvd. is a rural section. Peter Jefferson Parkway is an urban section. (iv) the proximity of the street to boundaries of the development and rural areas; The site is entirely within the development area. (v) whether the street terminates in the neighborhood or at the edge of the development area is otherwise expected to provide interconnections to abutting lands; Willis Drive will not be extended. Additional traffic will be served by Willis Drive as the hospital expands to intermediate phases and other adjacent properties are developed. (vi) whether a rural cross - section in the development area furthers the goals of the comprehensive plan, with particular emphasis on the neighborhood model and the applicable neighborhood master plan; To be determined by someone within Planning. (vii) whether the use of the a rural cross - section would enable a different principle of the neighborhood model to be more fully implemented; To be determined by someone within Planning. (viii) and, whether the proposed density of the subdivision is consistent with the density recommended in the land use plan section of the comprehensive plan. To be determined by someone within Planning. Engineering review finds no clear engineering benefits to the granting of the curb and gutter waiver. The use of curb - and - gutter will always direct flow more efficiently to the proposed storm sewer networks. However, the health and safety of the public would not be jeopardized with the use of the rural section because the road design meets the VDOT standards for an urban local road. Private Road Authorization: The applicant has not provided a letter requesting a private street. The letter requesting a waiver of the curb - and - gutter requirement and the plan set alludes to the need for a private street. And, as I mentioned in the introduction, under different conditions the private street could be authorized by the Chief of Current Development under section 14- 233.B.1. However, because Willis Drive connects two public streets and will serve through traffic, the Planning Commission must authorize the private street. [14- 234.C.4] 14 -234.B In considering a request for approval of one of more private streets, the agent and commission shall consider that: (i) private streets are intentded to be the exception to public streets; and (ii)absent compelling circumstances, private streets should not cross over dams or bridges or in involve other infrastructure that would be reasonably prohibitive to maintain, should not serve as the primary or sole interconnection between the subdivision and butting property, or serve through traffic by being the connector between two or more public streets. This road would carry traffic from the surrounding medical offices and the hospital. The estimated traffic provided by the applicant for this portion of the roadway is between 3,600 and 6,800 vehicles per day. 14 -234. C The agent and the commission may authorize one or more private streets in a subdivision if it finds that one or more of the circumstances in sections 14 -232 or 14 -233 exist and it determines that: 1. The private street will be adequate to carry the traffic volume which may be reasonably expected to be generated. This road would carry traffic from the surrounding medical offices and the hospital. The estimated traffic provided by the applicant for this portion of the roadway is between 3,600 and 6,800 vehicles per day. The road appears to meet the minimum VDOT guidelines for an urban local and collector streets (GS -7 and GS -8) found in Appendix A of the Road Design Manual but there is no maximum ADT specified for these design guidelines. 2. The comprehensive plan does not provide for a public street in the approximate location of the proposed private street. A public road is shown in the Comprehensive Plan. The applicant intends for the road to be public after the final phase of the hospital is constructed. 3. The fee of the private street will be owned by the owner of each lot abutting the right of way thereof or by an association composed of owners of all lots in the subdivision, subject in either case to any easement of the benefit of all lots served by the streets. Road will be maintained by the hospital. 4. Except where required by the commission to serve a specific public purpose, the private street will not serve through traffic nor intersect the state highway system in more than one location. All vehicles served by this road will be through traffic. 5. And, if applicable, the private street has been approved in accordance with section 30.3, flood hazard overlay district, of the zoning ordinance and other applicable law. Not applicable. The current horizontal, vertical, and cross - section design of the proposed private road meet the VDOT requirements for an urban local road. Therefore, all technical engineering concerns are addressed. However, since a request for private road authorization was never received by Current Development, a full engineering review of the issue cannot be supplied. A publicly maintained roadway around a hospital, even for the intermediate stages of its development, is something the public should prefer. Without reasoning for the request provided by the applicant, it is difficult to justify support for this waiver. Engineering summary and recommendation When the hospital first approached staff to discuss this issue, we replied that the following options, in order of preference, were available for Willis Drive: 1. No Phasing. Construct the road to the full width as approved. 2. Barricades. At the main hospital and employee entrances terminate the roadway and put a VDOT reflective barricade. If desired by the hospital, this option can include a private emergency access path if there is a problem on PJP. This would require the waiver of a few standards of the zoning ordinance for the path. 3. Public Rural Section roadway (suggested by the applicant). Redesign roadway with a rural section for the predicted traffic volumes for Phase I. This option would require a waiver from the Planning Commission per 14 -410H. 4. Private Rural Section roadway (suggested by the applicant). Redesign roadway with a rural section for the predicted traffic volumes in Phase I. This option would require two waivers from the Planning Commission: 14 -410H and 14- 234.C.4. The option considered now by the Planning Commission requires two waivers. Engineering review sees no technical reason to either approve or deny the two requests since VDOT standards are met. The issues at hand seems to be whether the Planning Commission wishes to deviate from the default standards outlined in the ordinance at the request of the hospital. If the Planning Commission decides to approve the two requests, engineering review recommends attaching a condition that requires the applicant to examine the need for left turn lanes into Parking Lot J and the Martha Jefferson Outpatient Care Site. In addition, engineering review requests that the Planning Commission consider including in their approval letter guidance to staff and the applicant regarding the time when the curb and gutter section must be built.
