K However, it should be noted that the County contracted with a consultant last year to study student generation rates in newer housing types (defined as constructed within the past 10 years) and the preliminary results of the study is showing higher student generation rates in newer MF housing (0.20 student per multi - family unit). At these preliminary rates, 161 students would be expected from 806 multi - family units. Project specific MF that have been built have shown a wide array of student impacts from extremely low (i.e. 1 or 2 students per 100 units) to as high as single family at approximately 73 students per 100. This variation is related to number of bedrooms, location and how and who the developer markets the project. Transportation Improvements Proposed The application materials included information on proposed transportation improvements: • Widening Eubanks Road in both directions • Installing two new 4 -way traffic signals on Eubanks Road • Adding additional turn lanes to each leg of the existing traffic signal at the Eubanks Road /MLK intersection Modifications to both the ingress and egress routes from the park- and -ride lot and BRT program. Orange County Transportation Staff Comments The North -South corridor should be shared by multiple transit agencies, including Orange Public Transit (420 Route), Triangle Transit, and Chapel Hill Transit (Interlining). The location of a northern terminus park and ride lot for connection to any future BRT in the MLK corridor should be considered during the review of the EDGE development. Keeping the proximity of the existing park and ride lot (downsized or structural) would facilitate 2 strong retail opportunities: one, allow commuters to shop nearby before return to exurbia and two, allow students from campus and MLK areas to shop and use retail and restaurants creating transit demand nodes at both north and south ends promoting efficiency. Stormwater The project is located in the Jordan Lake Unprotected Watershed and the Town of Chapel Hill enforces its stormwater regulations within its municipal limits. However, County staff may suggest increasing mitigation of stormwater impacts. While the development will be required to preserve stream buffers and install best - management type post - development stormwater management facilities, primarily for peak flow attenuation and nutrient export reduction, the County would be interested inassisting in one or more of the following: 1. Upgrading the proposed stormwater management facilities to a higher level of nutrient reduction, such as including bio- retention or stormwater wetlands, with the goal of reaching or beating export limits recognized by Orange County (2.2 pounds per acre nitrogen & 0.82 pounds per acre phosphorus), without compensatory mitigation. 2. Evaluating a portion of the adjacent property for an off -site regional stormwater management facility that would have a net neutral or positive impact on water quality, when contrasted with existing conditions.
