SUBJECT: Site Access Evaluation Ray’s RV Caldwell, Idaho
This memorandum summarizes the findings of a site access evaluation prepared for the proposed
truck repair facility to be located on the west side of Middleton Road, south of Ustick Road in Caldwell, Idaho. As proposed, the site will provide a single access drive off Middleton Road aligned opposite the full movement access drive serving Storelocal Storage. Supplemental access is proposed via a outbound only access drive. The purpose of this memorandum was to evaluate
the on-site circulation of articulated trucks and evaluate the need for a secondary access drive on
Middleton Road.
Existing Roadway Characteristics
Middleton Road is a north-south principal arterial roadway that in the vicinity of the site provides one travel lane in each direction. Middleton Road has a roundabout intersection with Ustick Road just north of the site. Between Ustick Road and Laster Lane, Middleton Road carries an annual average daily traffic (AADT) volume of 8,900 vehicles (ITD 2023) and has a posted speed limit
of 50 miles per hour. Middleton Road is under the jurisdiction of the Canyon Highway District 4.
Proposed Site and Development Plan
As previously indicated, the site is located on the west side of Middleton Road, south of Ustick Road and is currently divided into four parcels. There are no development plans for Parcels A and
B (which front Ustick Road) at this time. Parcel C is proposed to contain RV storage spaces and
Parcel D is proposed to contain a diesel repair facility. Access to Parcels C and D will be provided via a full movement access drive on Middleton Road aligned opposite the Storelocal Storage access drive, 1,075 feet south of Ustick Road. This access drive will provide one inbound lane and one outbound lane and outbound movements should be under stop-sign control.

This secondary access would be utilized for the purposes of discharging trucks from the proposed repair dock onto Middleton Road and for emergency access. At all other times, the access drive
will be gated and will not be utilized by site generated traffic on a regular basis.
Supplemental access to Parcel D only is proposed via an outbound only access drive on Middleton Road, located 145 feet south of the proposed full movement access drive which will provide a single lane. The purpose of this access drive will be to discharge repaired trucks from the building
onto Middleton Road without having these trucks circulate the east side of the building which has
the passenger vehicle parking spaces. This access will also serve as emergency access for the site. Estimated Utilization of the Supplemental Access Drive Based on information provided by the operator, it is anticipated that the repair facility will discharge approximately one truck per week and as such, the access drive will have limited usage
and will not impact the operations of Middleton Road. In order ensure that this access drive is not regularly utilized by other traffic generated by the site, it is recommended that it is gated at all times, except when discharging a repaired vehicle.
Truck Turning Analysis To evaluate the need for the supplemental access drive, AutoTURN exhibits (included in the appendix) were prepared for the on-site circulation of WB-65 trucks and fire trucks. The following
summarizes the findings of the AutoTURN exhibits.
• A WB-65 truck is not able to turn north from the repair bay, through the passenger vehicle parking lot, to access the full movement access drive without the elimination of passenger
vehicle parking.
• The provision of the outbound only access drive will allow for the more efficient circulation of emergency vehicles and will allow them to circulate the east side of the proposed repair building without backing to exit the site.
As such, the outbound only access drive will be beneficial in maintaining an efficient discharge of repaired trucks while maintaining the proposed passenger vehicle parking spaces and will enhanced circulation for emergency vehicles. Overall, this access drive will have little to no impact on Middleton Road.
Conclusions Based on the preceding site plan review and truck turn analysis, the following conclusions have been made:
• The traffic that will utilize the supplemental access drive will be limited, approximately one vehicle per week, and will be utilized to discharge repaired trucks.

• At all other times, it is recommended that the supplemental access drive be gated so it is
not utilized by the passenger vehicles.
• The supplemental access will also enhance the on-site circulation of emergency vehicles along the front (east) side of the building without needing to back up on site to egress the site.
• The supplemental access drive will have little to no impact on the operations of Middleton Road given its limited utilization and that it will be gated when not in use.
