Box 758 Greeley, Colorado 80632-0758 RE: U ■- e erence No. 98-169 Dear Mr. Hempen: We have completed our traffic engineering review of the proposed Elms at Meadow Vale PUD site plan and traffic study for the development to be located on the southwest corner of WCR 5.5 and WCR 26, north of the Meadow Vale Farm development, east of Longmont. This letter provides our comments on both the traffic study (prepared by Matthew J. Delich, P.E., in May 1998) and the plan. TRAFFIC IMPACT STUDY In general, the traffic study prepared for the Elms at Meadow Vale is complete and was prepared using the most recent trip generation and intersection capacity techniques. We do offer the following comments: • No trip distribution was assigned to the north of the site; all of the traffic was assumed to utilize SH 119/WCR 5.5 to access the site. It is likely that some of the site generated traffic would access the site to/from the north. Both WCR 5 and WCR 7 are unpaved and provide a connection to SH 66, which extends east/west between 1-25 and northern Longmont. • The intersections of WCR 5.5/WCR 26, and WCR 5.5/site access were not analyzed in the study; the study focused on the intersection of SH 119/WCR 5.5. Currently, the intersection of WCR 5.5/WCR 26 does not have any traffic control. As mentioned above, it is likely that some of the site traffic would access the site to/from the north, therefore using this intersection. A STOP sign should be installed on the WCR 5.5 approach of this intersection. Additionally, the site access on WCR 5.5 should be STOP-sign controlled for traffic exiting the site access. 303.721.1440 fax 303.721.0832 thu@thueng.com Greenwood Corporate Plaza �AHIOaT 7951 E.Maplewood Ave. Ste. 200 En,Ic uxxi CO 801 I I 982236 aia August 21 , 1998 Mr. Frank Hampen, Jr. Page 2 • The intersections of SH 119/WCR 5.5 and SH 119/WCR 3.5 are both identified as locations for potential signal installations in the future on Map 2.2, titled "Structural Transportation Network", of the Weld County Mixed Use Development Plan Standards (Ordinance 191, February 1997) (WCMUD). It is our opinion that only one of these signals will be warranted, even in the long range future. As traffic volumes increase, both locations should be monitored to determine which should be signalized. SITE PLAN The site plan was also reviewed for meeting general traffic engineering principles, and a field trip was made to verify physical characteristics of the site. Following is a list of concerns based upon the plan and/or the field trip: • It is recommended that a second site access be considered. At build out, the site is expected to generate approximately 1900 vehicles per day (vpd). This volume suggests at least a collector is needed (arterial according to County Standards) as the entry road and that home frontage not be allowed. The plan proposed home frontage along the entry roadway and a second access (perhaps to WCR 26) would relieve this concentrated demand. A second site access may also be beneficial for emergency service reasons. Providing the second access onto WCR 26 may also better serve the site if the WCR 3.5 intersection with SH 119 is signalized and the WCR 5.5 intersection is left unsignalized. • The WCMUD Standards state that a two-lane, collector roadway should have a ROW of 80 feet, including two 12-foot driving lanes, a painted median turn lane, and two six-foot bike lanes. From field measurement, the existing ROW appears to be approximately 50 feet on WCR 5.5 and 56 feet on WCR 26. The plan identifies WCR 5.5 and WCR 26 to each have a cross section of 60 feet with two 14-foot travel lanes and 16 feet of shoulder/ditch on each side. • The WCMUD Standards indicate local, residential streets should have 60 feet of ROW, including two 12-foot travel lanes, two 8-foot parking lanes and 10 feet of curb and gutter, sidewalk, etc. on each side. For the local roads proposed for within the site, the plan identifies the following: • Boulevard - 112 feet of ROW with two, separated 12-foot travel lanes and eight feet of parking on each side, a fifty foot landscaped median and two eleven-foot shoulders/ditches. • Local Street - 60 feet of ROW with two 14-foot travel lanes, no on-street August 21, 1998 Mr. Frank Hampen, Jr. Page 3 parking, and 16 feet of shoulder/ditch on each side. • Private Drive - 32 feet of ROW with two 10-foot travel lanes and six feet of shoulder/ditch on each side. Neither the local street nor the private drive described in the plan meet the Weld County Standards for local, residential streets. The largest concern is that there is no on-street parking for the majority of the proposed development. Additionally, there is concern that emergency vehicles may not be able to maneuver in the planned Private Drive areas. • It is understood that the elementary school was included in the previous study and plan completed in March 1995 for Meadow Vale Farms. Planning for the school should incorporate pedestrian and vehicle access from within the neighborhood. Vehicle access to the school should also be provided from WCR 5.5 if the school is not to be served by a collector road within the already approved Meadow Vale Farms development. • The plan identifies planned landscaping, including trees and bushes, along the roadway within the site. The location of the landscaping should be carefully determined to ensure proper site distance is provided at intersections.

In reviewing the proposal for the Elms at Meadow Vale PUD site plan and traffic study,additional information and requirements are as follows: The existing traffic study information only identifies movements from the Elms south to State Highway i . G 119. Additional information will be required for traffic flows to the north and impacts at the intersection of WCR 5.5 and WCR 26. Stop signs shall be installed at all approaches to WCR 5.5 and WCR 26. The consultant agrees with the requirement of a secondary access onto WCR 26 which will be installed (- to relieve additional traffic loads at the north end of the Elms. All these items shall be addressed prior to recording the final plat. Attached is your copy of the traffic analysis provided by our traffic consultant.
