The request may affect future transportation planning for the Pantops area. This report will briefly discuss the typical critical slope waiver request items and then will focus on the proposed road alignment for Olympia Drive. Description of the project, critical slope area, and proposed disturbance: This project is proposing the extension of Olympia drive to connect with the recently approved Town & Country Lane (Phase I). Town and Country Lane will connect with Rte 250; therefore creating a new connector road to Rte 250 for the residents of Fontana. The critical sloped areas of the site are mainly wooded and run to a stream on the northern border of the parcel (TMP 78 -09). The proposed disturbance areas will include the Olympia Road extension, grading to make the placement of the road possible, as well as Erosion Control measures such as Sediment Traps, and permanent Stormwater Facilities. Figure 1 on the following page shows the critical slope areas and the disturbed critical slopes. The summary of disturbance is as follows: Areas* Acres Total site 16.1 acres approximately Critical slopes 6.1 acres 380/. of site Critical slopes disturbed 3.6 acres 59% of critical slopes_ *In addition, there is proposed grading on adjacent parcel TMP 78 -11 to connect the road to the existing (and currently under construction) Olympia Drive. There is a small area of critical slopes (around 5000 square feet) which is proposed to be disturbed (See Figure 2 on the following page.). Exemptions to critical slopes waivers for driveways, roads and utilities without reasonable alternative locations: This disturbance is not exempt. The road can be moved further away from the stream. Its current location is to allow for more development between the new road and Rte 250. Compliance with Zoning Ordinance 18 -4.2: "movement of soil and rock" Proper slope construction, control of drainage, and vegetative stabilization will prevent any movement of soil. "excessive stormwater runoff' Stormwater runoff will run down to the stream which borders the northern portion of the property. The stream flows into the 100 year floodplain, which begins at the very north- western tip of the property. (There is no disturbance proposed inside the limits of the 100 year floodplain.) "siltation" Inspection and bonding by the County will ensure siltation control during construction. Proper Albemarle County Community Development Page 2 of 6 stabilization and maintenance will ensure long term stability. "loss of aesthetic resource" A significant portion of wooded area is proposed to be removed in order to put in Olympia Drive. A portion of the site north of Phase I (the Guadalajara site) was previously the site of the old Town & Country Motel. The proposed road will be visible from Wilton Farm, Avemore, and portions of Fontana. "septic effluent" Septic effluence is not an issue, as the site and areas around it are served by public sewer.

The main concern is whether or not the road configuration is the best configuration for serving traffic in this area. Currently, a County and City of Charlottesville funded study is under way to find the best possible alignment for the Eastern Connector Road. The alignment of the proposed Olympia Drive /Town & Country Road intersection is part of the study. The study is anticipated to be completed in the Spring of 2008. The alignment for Olympia drive has yet to be identified. Figure 4 below shows the current Pantops Master Plan layout of Olympia Drive, Town & Country Road, and Rte 20. (this layout precedes the study now underway and may change) Figure 5 provides more details of the proposed layout for Town & Country Phase II and Figure 6 shows a possible alternative layout.

JL .o Figure 5 - Proposed Town & Country Phase II Layout: Beneficial if it is used primarily for traffic coming onto Rte 20 (red) from Rte 250 (in orange). However, if the majority of the traffic is going onto Rte 20 from the existing Rte 250 and Rte 20 intersection, then traffic on the proposed Olympia Drive will have to make an unnecessary stop to get onto Rte 20.

The remainder of the site should wait until the Eastern Connector Road study is complete. The intersection may play a key role in the study, and approving the proposed layout before the study's completion may preempt, or limit the effectiveness of the study.
