The following specific_ concerns are m presented: CO - Trip generation - Trip distribution - Access locations - PJeed for signals - Signal progression - Road geometrics This study relates to the conceptual plan prepared by Cityscape Urban Design, Inc. dated Plarch b, 198?. t4o specific development proposal is part of this submis- sion. The master plan is presented in a conceptual sense. (4hen specific development proposals are put forth on all or part of the land, a detailed traffic co z study should be performed. cc w w z Streets Ww z This proposed development is located in the c� southwest quadrant of the Harmony Road and Timberline = Z Road intersection in Fort Collins, Colorado. Harmony ea o Road and Timberline Road are classified as major < arterials. In this. area, Harmony Road is a four lane .� Wo a highvi.a.y with a. center median. Currently signals exist cn at College, Lemay, and Timberline. Harmony Road is also - a S.H. 68 and is considered to be an access controlled °-` highway. Speed limits are generally 55 mph vaith a re- ' duction to 45 mph approaching signalized intersections. 3 _ < Timberline Road has a. paved tvio lane rural cross. cc `- section north of Harmony Road and a gravel surface south Q of Harmony Road.

"Warrants for Traffic Control Signals", Traffic Encineerinq, November 1967. "DOTES: 1. Minor street ADT of 3600 (one -lane) and 4800 (two-lane) have been accepted in some instances as meeting Warrant I requirements. 2. For one-way minor street, reduce minor street ADT requirement by 33-1/3%. - Access from Harmony Road can be made at two locations, one being at the intended signalized intersection 4Ma i n Access) . The other is to the west in the area. of Parcel A and it wi 1 1 have stop sign control with limited turns. The location shown on the master plan is reasonable from a signal progression point of view.. - Primary access is also intended from Timberline Road (CR 11) . The 1 ocat i on=_. shown s.houl d al 1 ow ful 1 turn access. This should be further evaluated in future traffic =.tudi e=_.. - Figure 3 shows the long range lane requirements on the area roads and streets. These geometrics are based upon the traffic volumes shown in Figure 2. This preliminary traffic study only addresses the traffic impacts in a. generalized manner and is only appropriate for the master plan submitted. It is recommended that a more detailed traffic study be considered as the various elements of this project advance through the planning process. Conclusions The fol 1 ow ng concl us ons are drawn from th i s preliminary traffic analysis of the Stromberger Property Master Plan: - It is expected that this proposed development, at full build -out as described, will generate approximately 9500 vehicle trip ends on an average weekday. - Signals w•!i 11 1 ikely be viarra.nted wi th ful 1 development of the Str•omber•ger Property Plaster Plan at the Harmony Road/Main Access intersection. - The accesses shown in the master plan are at reasonable locations and are in conformance with the Harmony Road Access Plan. - The on -site road system w,►i 1 1 serve the land uses. and provide access to adjacent properties. Adjustments to the circulation system can be made when specific land use proposals are put forth. - The geometric requirements along Harmony Road are in basic accordance with the Fort Col 1 i n=. Master Street Plan. 4 W Z LANE REQUIREMENTS FIGURE 3 0 - Additional traffic studies should be conducted t,,ihen specific development proposals are put forth.
