. . ~. TllnothyJ.~dson -7- February 25, 1997 5) Traffic analyses should account for all roadway changes that are anticipated to occur by the year 2001. For example, the City is planning to construct Twin Lakes Parkway east of Cleveland Avenue. The first phase of this project is the segment immediately east of Cleveland Avenue at the location of the existing ramps to and from the north on 1-35W. It is imperative that the analyses account for the planned Twin Lakes Parkway and associated revisions to the intersection on Cleveland Avenue. 6) Traffic analyses at the intersections with the ramps to and from 1-35W should account for the metering that Mn/DOT utilizes for the on-ramps. Extensive queues presently are experienced on Cleveland Avenue during the p.m. peak period due to the metering on the entrance ramp to northbound 1-35W. 7) Traffic study report should correctly identify the function of Cleveland Avenue, County Road C, and County Road D. The report incorrectly labeled these routes as collectors. All three routes are minor arterials, with portions of each designated as A minor arterials. 8) Site plan should be revised to provide access on Cleveland Avenue that is consistent with the A minor arterial designation of that route. The site plan shown in Figure 4 of the EAW shows eight access points along Cleveland Avenue. This frequency of access is much greater than the standard for A minor arterials. The number of access points needs to be reduced in order for Cleveland Avenue to safely and efficiently serve its A minor arterial function. 9) Trip generation and trip distribution projections should be reviewed and updated as needed to represent valid forecasts. We noted several errors in the trip generation projections presented in the existing study report. The trip distribution projections need to be carefully reviewed because the existing study report utilized the same projections, with just two minor changes, that were used in the 1985 report. In closing, I would ask that you forward this comment letter to the City of Roseville for their use in making decisions about the Centre Pointe EA W that are consistent with the needs of the City and with applicable State Rules. Let me know if you have any questions about the points addressed in the letter. Sincerely, ~:~~:crc.
