e e Ms. Debra Bloom March 3, 1999 Page 2 The other permitted uses include hospitals and rest homes for which the site is relatively small. A rest home would generate very little traffic. The volume of traffic generated by a private club or a lodge is very dependent on the type of facility, and would have a sigr;tifiGant.:range in generation based on type of facilities provided and the timing of the activities. . A question also related to being able to quantify the additional delay which would occur with the traffic from the Lyndale Garden Centers. This would be difficult to do without first collecting the data on the existing delays at the intersection, data which is currently not available. The two primary delays at the Snelling A venue intersection will be the northbound left turn from Snelling A venue to Oakcrest A venue and for the eastbound left turn from Oakcrest A venue to northbound Snelling Avenue. We anticipate that there will be ten northbound left turns in the p.m. peak period. These will have to use gaps in southbound traffic on Snelling A venue being created by the signal at County Road C. There will be some delay for this traffic but our observations are that there is an adequate number of southbound gaps for this traffic to turn left through although some long delays do occur. The ten additional vehicles will mean one additional vehicle every six minutes or approximately, in peak periods, one vehicle every fourth signal cycle at County Road C. The major concern is the eastbound to northbound left turn from Oakcrest Avenue. We anticipate approximately seven in the p.m. peak hour from Lyndale Garden Centers. These seven vehicles will have to wait not only for a gap in southbound traffic, but for the northbound left turns to clear through the gap and then find a gap in northbound traffic. This will be difficult in the p.m. peak hour as it is for existing traffic. We have observed, on a limited basis, some traffic being able to turn very quickly onto Snelling A venue while other traffic seems to be waiting for a minute or longer. Adding seven additional vehicles will add to the overall delay of existing traffic as well as creating delays for the newly generated traffic. However, with only seven vehicles plus the small number of existing eastbound and northbound left turns, the total amount of delay should be relatively small compared to the overall traffic flow in the intersection. Comparisons should be made to other types of use permitted on the site. We have indicated that we assume 46 total p.m. peak hour trips from the Lyndale Garden Center which would be a high seasonal estimate. This would be significantly less at other times of the year. This is approximately 60 percent of the volume which could occur from a 20,000 square foot office building. Based on peaking characteristics, it would have about the same impact as a 20,000 square foot general office building. This compares the average peak hour throughout a year for the general office building with the design peak hour, which is almost a worst case, for the Lyndale Garden Center. There are also questions regarding the impact on the intersection of Oakcrest A venue and Fairview . Avenue. We anticipate that much of the traffic traveling from the Lyndale Garden Center to Fairview A venue will make a right turn on Fairview A venue and will have minimai impact on the total volumes, other than in the westbound backup of traffic waiting at the intersection. If a traffic signal is ultimately installed at the intersection, there would be very little impact.
