• All visitors to the site will be required to check in at the Saunders field office • Construction workers will be required to park on-site at all times. Construction parking on public streets will not be allowed. Workers discovered to be deliberately parked off-site will be permanently removed from the project. • Direct site deliveries will be scheduled during work hours to minimize impact to the neighborhood. • Any disruption to the normal flow of public traffic or right of way access will be addressed with traffic control plans and/or flagmen to minimize impacts to local traffic. Updates/Improvement Measures as of 2021 • The development team has been in touch with the city to request speed radars/photo radar enforcement vehicles on 4th street, Dellwood and Alpine to further enforce the 20mph speed limit • We've also inquired about putting 3 hour parking in place on 4th Street and Mapleton Ave bordering the 311 site. Our hope is that having this measure in place will further discourage subcontractors to park on public streets. If they do they will have to pay the fine, and ideally they'll learn that paying that fine isn't worth it.

311 Mapleton is mostly a balanced site, so Saunders will not be continuously routing trucks, as was the case during demolition. Hauling and material deliveries will vary depending on the period of the project, so the total number of trips during the construction phase cannot be quantified. The development team will communicate with subcontractors throughout the development process to obtain estimated trip numbers for the different aspects and activities that require hauling or heavy impact deliveries. TIMELINE Infrastructure and construction are anticipated to take between 18 - 24 months from the demolition completion date of May 1, 2020, which puts the completion date of the project in the summer of 2022. • Hauling will be active for the duration of infrastructure and construction; however, it will not be continuous, as was the case with demolition. It will pause and resume intermittently as necessary to allow for other work. • Material deliveries will vary depending on the point of the project as well, and updates will be posted on the development website to inform the public of any increase in these activities. • The development team will limit trucking on Saturday to provide a break for the neighborhood to the greatest extent possible. ENFORCEMENT MEASURES • A daily written plan of the required truck routes will be distributed to any truck coming to the job- site in advance. • A large, double-sided sign with the truck routing plan is present at the entry/exit to the 311 Mapleton site, so all trucks are aware of the requirements. The development team will work to have trucks follow the dedicated routes to the best of their ability, but as previously stated, it’s not going to be perfect. If trucks are found taking an unapproved route, the team will intervene to find the cause, and redirect trucks to one of the approved routes when applicable. The development team desires to finish this project as quickly as possible to shorten the duration of impact to the surrounding neighborhood, so trucks will be routed to the best available route in certain instances (for example, weather conditions, road impediments, etc.). If you notice a truck on an unapproved route or have any other trucking-related questions or concerns, please email or call The Neighborhood Liaison at info@311mapleton.com | 720-507-7537. Pictures, videos, or detailed descriptions are strongly encouraged so the development team can identify if the truck is associated with the 311 site and take steps to rectify the issue to the best of their ability. TRUCK ROUTES AND STAGING LOGISTICS Hours of operation are 7:00 a.m. – 5:00 p.m. Monday – Saturday per the City of Boulder Municipal Code. Hauling and heavy impact delivery trucks will not be permitted to make their way to the site before 7:00 a.m. • Two dedicated trucking routes will be used for hauling and heavy impact deliveries, as shown on the Truck Routing Map. All semi-truck sized vehicles are required to take these routes. • Personnel vehicles and other trucks can utilize any of the available public roads. • It is desired to alternate trucking routes every other day when possible. Trucks returning to the job site will take the same routes. Routes will alternate as follows: • Monday, Wednesday and Friday: 4th Street to Dellwood, 9th to Balsam to Broadway • Tuesday, Thursday, and Saturday: 4th Street to Alpine to Broadway • The development team has been in contact with the Mapleton Early Childhood Center at 9th and Mapleton regarding construction activities. Given the multiple pick up and drop off times the school has throughout the day, and other logistics related to trucks being able to navigate safely and efficiently, Mapleton Avenue will not be used for export or heavy impact deliveries. The ownership group will continue to work with Mapleton Early Childhood Center throughout the project to address any potential concerns. • Dirt and other debris will be stockpiled on-site as much as possible and trucked off when required. • All trucks waiting to be filled will be staged on-site, not in the public right of way. • Trucks will not be allowed to idle during warm weather days when possible. • Dust mitigation - water trucks will be utilized to reduce dust during demolition and construction. • Mud mitigation - stormwater protection measures are maintained on-site and streets will be swept periodically as necessary. • Truck routing and staging plans have been submitted and approved by The City of Boulder.
