. . . . Mr. Dan O'Brien -7- August 4, 1994 Daily traffic volumes for Dodge Ave. were also developed. The same growth factor used for the p.m. peak hour turn movement volumes was applied to the 1994 daily volume, resulting in 1996 base daily volume without the proposed development. The expected number of daily trips generated by the development were added to the 1996 base volumes resulting in 1996 post-development daily traffic volumes. These volumes are shown in Figure 4. TRAFFIC ANALYSIS Abilitv of Adiacent Roadways to Accommodate Pro DOSed DeveloDment Traffic Based on current daily traffic volumes, it is apparent Dodge Ave. is serving as a collector route for this area. According to Minnesota State Aid design standards, the existing 30 foot width is not sufficient for a two lane collector with on-street parking on one side. The State Aid design standards recommend a 36 foot curb face to curb face width for a two lane collector with parking on one side. Therefore, Dodge Ave. needs to be widened sometime in the future even without any additional development in the area. However, the need to widen Dodge Ave. between Elk Hills Dr. and 189th Ave. becomes more urgent due to the additional traffic generated by the proposed development. Therefore, it is our recommendation that Dodge Ave. between Elk Hills Dr. and 189th Ave. be widened to 36 feet curb face to curb face in conjunction with the proposed development. Such widening should be accomplished according to City standards, including consideration for all pertinent items, such as a possible sidewalk. All of the above mentioned improvements to Dodge Ave. will fit within the existing 66 foot right-of-way. The recommended conceptual layout is shown in Figure 5. With these improvements, we are confident the adjacent roadways will be able to effectively accommodate the additional trips generated by the proposed development. Elk Hills Dr.lDod2e Ave. Intersection In order to accommodate the additional development traffic at this intersection, it is recommended that the following measures be implemented: A right turn only lane be added for southbound traffic on Dodge Ave., creating a two lane approach (see Figure 5). Convert the intersection to four-way stop sign control, except that right turns from the west to the south would continue to utilize a channelization island and operate with yield sign control. The recommended conceptual layout for Dodge Ave. is shown in Figure 5. With these improvements we are confident the intersection will be able to accommodate the traffic volumes generated by the proposed development. T.H. 169/Elk Hills Dr. Intersection A capacity and level of service analysis using post-development volumes showed all movements at a level of service D or better utilizing planned improvements to the intersection layout. Therefore, we believe this intersection will effectively accommodate the post-development traffic.
