products or other materials, except water. Describe any emergency response containment plans. No known above or below ground storage tanks are known to be on the property. 21. Traffic. Parking spaces added 690 at buildout, 330 parkine spaces added with current projects (see detail belowl. Existing spaces (if project involves expansion) 1,400 existin�parkine spaces. Estimated total average daily traffic generated . Estimated maximum peak hour traffic generated (if known) and time of occurrence .(A net increase of 238 u.m. peak hour trips and 365 p.m. peak hour trips are anticipated from campus expansion at buildout.) Provide an estimate of the impact on traffic congestion on affected roads and describe any traffic improvements necessary. If the project is within the Twin Cities metropolitan area, discuss its impact on the regional transportation system. This Project is anticipaled to have minimal impact on the Twin Cities Metropolitan Regional Highway System. Parking: Currently there are about 1, 400 parking ,rpaces on the Northwestern College campus north of Lydia Avenue. Estimates of peak parking demand were made based on hourly vehic(e counts collected via the 48-hour traffic tube counts taken in Apri/ 2006. Peak demand is estimated to occur between 12: IS and 12:30 p.m. on a typical weekday and consists of about 1,365 parked vehicles, or 97% ojparking capacity. For the first three projects there will be 495 spaces added in the Parking Ramp, and 165 spaces lost with the construction of the Community Life Center, for a net total of 330 new spaces in the current projects. Additional parking is proposed ta be added, with a total parking space increase to 2,090 spaces, a net increase of 690 spaces. The College will consider incorporating parking structures into any new construction in an effor-t to minimize tlze impacts of increased parking needs throughout the etttire campus. Traffic: Existing a.m. and p.rn. peak hozrr trnfJic conditions H�ere modeled using Synchro/SimTrajfic simulation software at four stardy intersections including Fairview Avenue/Lydia Avenue, Lydia Avenue/College Entrance/Lincoln Drive, Lydia Avenue/Snelling Avenue, and Snelling Avenue/County Road C-2. All study intersections currently operate at acceptable levels oJservice overall (i.e., LOS D or better) in both the a.nt. and p.m. peak hours. However, several intersection approaches currently operate below LOS D, including the southbound approach at Lydia Avenue/College Entrance/Lincoln Drive and the eastbound approach at Snelling Avenue/County Road G2 which operate at LOS F during the p.m. peak hour. Vehicles exiting the campus gate in the p.m. peak hour experience about 61 seconds delay on average due to limited gaps in the east-west trajf:c�low on Lydia Avenue during that period. Also operating below LOS D are the eastbound and westbound approaches of Snelling/Lydia (LOS E in the a.m. and p.m. peak hours, respectively) and the eastbound approach at Snelling/County Road G2 in the a.m. peak hour (LOS E and LOS F in the a.m. and p.m. peak hours, respectively>). Future trip generation due to campus �,rpansion and corresponding increases in student enrollment, faculty, and staff, was estimated for the a.m. and p.m. peak hours. These estimates were based on existing hour-by-hour gate counts taken in Apri12006 which were used to calculate the current rate of peak hour trips per total commuter students, faculty and staff. This calculated rate was then applied to the projected future year commuter student, faculty, and staff populations to derive trip generation totals. Incoming and outgoing trips were determined based on the hvo-directional gate count data. The total net increases in campus-related trafftc turn movements estimated for Year 2018 (at Master Plan buildout) are shown in Attachment 20 (Figure No. 3 from the Trafftc Impact Study). A net increase of 238 a.m. peak hour trips and 365 p.m. peak hour trips are unticipated_from campus expansion at fu!l buildout. The distribution of campus-generated trips was estimated hased on existing commuter student, faculty and staff residentia! zip codes. The most signiftcant impacts of the proposed campus expansion are projected to occur at Fairview Avenue/Lydia Avenz�e and at the College entrance at the intersection with Lydia Avenue and Lincoln Drive. At Fai�view Avenue/Lydia Avenue future trafJic operatioris would fall to LOS D overall, and the southbound approach would drop to LOS E due in part to campacs-generated traffrc moving through Page ! I
