1. How is the Town communicating its designated truck routes to businesses?

Public Works staff will coordinate with the Communications Department to provide an update to businesses and the community about the routes. Town Staff will install signage to guide drivers to the appropriate routes and give notice to the public. Staff are following a communication plan that includes emails to stakeholders, including: Chamber, Economic Development Council, the Colorado Motor Carriers Association, and specific businesses that have regular truck traffic. There will also be social media posts, a news release, and letters mailed to specific businesses by Town staff.

2. What is the Town doing to make sure that businesses are following the routes?

Businesses will be made aware of the truck routes and program through a robust communication plan. The Castle Rock Police Department will focus its efforts on the enforcement and education of motorists on the law. If truck drivers are traveling off route, they would need to provide Castle Rock Police Department (CRPD) evidence of business in the area to justify their presence. If needed, CRPD could dedicate members of their team for directed enforcement which can speed the educational process. Communication will continue between Public Works and the Police Department as the program matures.

3. What is the expected traffic increase for roads along the truck route?

Traffic counts were taken in April 2022. The counts show that of the total average daily traffic (ADT) on corridors, trucks were less than 5% of overall traffic on state highways, and between 1% and 3% on the Town's major arterials. This is a below-typical percentage of trucks (usually between three to 6%) on these types of roadways. Since the overall total number of trucks routing through Town will not be influenced by the implementation of a designated truck route program, truck volumes are not anticipated to change on Wolfensberger Road, Lake Gulch Road, Highway 86 east of Founders Parkway/Ridge Road or Highway 86 north of Meadows Parkway. With the implementation of truck restrictions on Gilbert Street and Wilcox Street, there will be a very small increase in the number of trucks along Founders Parkway, Plum Creek Parkway and Ridge Road. However, the increase of trucks along these roads is anticipated to be less than 100 trucks per day. In addition, the implementation of the truck route would result in a reduction of trucks on Gilbert Street and through Downtown by 130 or fewer trucks per day.

The table below shows the existing truck volume and percent of trucks and the forecasted truck volume and percent of trucks along routes where implementation of the designated truck route program will increase or decrease overall truck traffic.

Existing and projected truck traffic with the implementation of the designated truck route program

Roadway	Location	Average daily traffic (ADT)	Existing truck volume (April 2022)	Existing percent trucks of ADT	Projected truck volume with designated truck routes	Projected percent of trucks with designated truck routes
Founders Parkway	North of Highway 86	20,826	360	1.7%	427	2.1%
Ridge Road	North of Enderud Boulevard	14,366	140	1.0%	207	1.4%
State Highway 86	East of Founders Parkway	17,635	315	1.8%	315	1.8%
Plum Creek Parkway	East of Gilbert Street	21,749	168	0.8%	235	1.1%
Plum Creek Parkway	Near Perry Street	22,938	174	0.8%	241	1.1%
Fifth Street	East of Woodlands Boulevard	11,711	134	1.1%	5	0.04%
Wolfensberger Road	West of Prairie Hawk Drive	5,656	69	1.0%	69	1.0%

As shown in the table, the overall percent of truck traffic is expected to increase by 0.3% on Plum Creek Parkway, 0.4% on Ridge Road, 0.4% on Founders Parkway and reduce by 0.7% on Gilbert Street. Note that the above figure is an estimation and the projected five trucks on Gilbert Street are representative of local deliveries still being allowed under the designated truck route program.

4. Will the Town be monitoring noise levels from the truck traffic?

Members of the Castle Rock Police Department have reviewed the designated truck route program, and feel it is a great way to keep trucks on the major thoroughfares and out of neighborhoods and residential streets. Public Works will continue to coordinate with police to address noise complaints associated with truck traffic using decibel meters. The volume level of truck noise is not likely to change.
