Planning & Zoning file #33-07 Page 4 Steve Olt - SanctuaryWestPDP,TrafficOF ionsComments.Letter2.doc Page 3 your western access will experience significant difficulty making left turning movements as well. The City also is concerned with this projects Southbound Left traffic from the eastern access. Its motorists frustration with waiting to get a gap in LaPorte Avenue traffic competing with the Northbound Left from Briarwood Road, especially since the separation of the two intersections is less than City standards and offset to a negative aspect regarding conflicting Left Turn safety conditions. The City sees all of this as a mix for realistic safety problems due to frustrations. Please provide discussion of how this site can provide reasonable and safe outbound movement conditions for its residents during the peak AM rush hour, due to these current existing conditions. The discussion of poor LOS at side streets to arterials is not applicable here as the issue is not mere lower quantity of gaps, but nearly constant blocking of one half of your project access during the peak AM rush hour. The other half of the project access experiencing the more traditional failing condition during the AM commute. Sums up to high frustration and safety concerns for AM commuting. Number: 113 Created: 11 / 15/ 2007 [11/15/071 In 2009 the District high schools are to incorporate the 9th grade level once again. Please contact PSD to gain some expectation of the additional number of students the high school will gain and do include that in your analysis of short term and long term conditions at the area intersections. Number: 114 Created: 11 / 15 / 2007 [1 l/ 15/071 Per Figure 8-1 of the LCUASS, this project will need to provide an east bound left turn lane at its west access. It may be negotiable to forego the left turn lane in favor of a reversible lane east of your west access to provide a 2 stage left turn capability from the west access for your residents trying to turn onto east bound LaPorte Avenue during the AM rush hour. Number: 115 Created: 11 / 15/2007 [1l/ 15/07] The TIS did not include any pedestrian and bicycle impact evaluation as required in LCUASS 4.5.3.B. Please evaluate bike and pedestrian LOS in the revised TIS. Number: 116 Created: 11 / 15 / 2007 [11/15/07] Based on possible conditions near the easterly project site access from LaPorte Avenue, please provide an accident analysis/forecast for the short term period. If you have any questions regarding these issues related to this project, please feel free to call Ward at (970)221-6820 or me at (970)221-6341. Yours Truly, Page 3 Steve Olt - SanctuaryWestPDP,TrafficOp ionsCommentsletter2.doc Page 2 Number: 107 Created: 11 / 15 / 2007 [ 11 / 15/07] City would like an on -site review of the witnessed delay experienced at the Westbound Through & Left Turn at LaPorte Avenue and Impala Drive of each 15 minute period from 7:15 AM to 8:00 AM. City would also request a gap study be performed on LaPorte Avenue at Impala Drive for the same time period. Number: 108 Created: 11 / 15 / 2007 [11/ 15/07] City requests an analysis of the delays that maybe experienced by southbound left turning traffic from both access drives to this project, for the 15 minute periods between 7:15 AM and 8:00 AM. Number: 109 Created: 11 / 15/2007 [11/ 15/07] City requests a queue analysis for the Eastbound Left & Through Right at Taft Hill Road and LaPorte Avenue between the 15 minute periods between 7:15 AM and 8:00 AM. Number: 110 Created: 11 / 15 / 2007 [1 l/ 15/07] There is a road improvement project planned for this spring at Taft Hill Road and LaPorte Avenue. It will add an exclusive Southbound Right lane, an exclusive Eastbound Right lane, and will add a second Southbound Through lane, southwards from the intersection. Please analyze this improved intersection in Existing, 2012 Background and Total, and 2027 Background and Total. Number: 111 Created: 11 / 15 / 2007 [ 11 / 15/07] Traditionally the City uses 5 years as the short term analysis period. Please revise calculations to reflect a 2012 short term analysis. Based on current nationwide mortgage and housing issues, 2009 is felt as to near of a short term condition. Number: 112 Created: 11 / 15/2007 [11/ 15/07] The most significant difficulty the City sees at this location is the difficulty the residents of this project will experience each morning leaving for their daily commute. The current on -street conditions are a heavy west bound left turning movement at LaPorte Avenue0 and Impala Drive, plus significant east and west bound thru movements on LaPorte Avenue as well. The west bound left queues back into the west bound thru movement for about 20 minutes each day at Impala Drive during the peak rush hour, effectively blocking this projects southbound left turn movements nearly completely at your eastern access. Due to the volume of east and west bound thru traffic, Page 2 CSteve Olt - SanctuaryWestPDP,TrafficOp ionsCommentsletter2.doc Page 1 STAFF PROJECT REVIEW City of Fort Collins Vignette Studios Date: 11/26/2007 c/o Terence Hoaglund 144 North Mason Street, Suite 2 Fort Collins, CO 80524 Ward Stanford of Traffic Operations has reviewed your submittal for SANCTUARY WEST PDP - TYPE 1, and he has offered the following comments: Department: Traffic Operations Issue Contact: Ward Stanford Topic: General Number: 101 Created: 11 / 12 / 2007 [1 l/ 12/07] Need to show all drives and public streets on the south side of LaPorte Avenue. Number: 102 Created: 11 / 12 / 2007 [11/ 12/07] Please provide a Signing and Striping plan of LaPorte Avenue from 500' east and west of your project accesses plus any internal street larger than a Local Residential. Topic: Traffic Number: 103 Created: 11 / 15/2007 [11/ 15/07] No scoping session was held. That is the first thing to be done for the generation of the Transportation Impact Study (TIS), per LCUASS standards. Number: 104 Created: 11 / 15/ 2007 [11/ 15/07] The TIS distributions are pretty good but from our point of view the distributions need to be adjusted a minor amount to 40% Eastbound, 15% Taft Northbound. The remaining are fine as shown in the TIS. Number: 105 Created: 11 / 15/2007 [11/ 15/07] The LOS per approach and intersection overall for Taft Hill Road and LaPorte Avenue differ significantly between my City data and the TIS results. Number: 106 Created: 11 / 15/2007 [11/ 15/07] The TIS's 2009 TOTAL is on par or less than the City's 2007 EXISTING at Taft Hill Road and LaPorte Avenue. I would prefer that the TIS use the City's counts at this intersection as well as using the calculated PHF or 0.85, whichever is larger.
