Changes from 2024

Reservoir challenges

Though Blackridge Reservoir is one of the highlights of our community, its popularity comes with a list of challenges that relate to overcrowding during peak times. Parking space on site is limited, to which some drivers respond by illegally parking in permit-only areas in nearby neighborhoods. Various nuisances are a recurring issue at the reservoir and in the vicinity. When crowds are their largest, police presence is often needed, pulling officers away from patrols around the rest of the community or costing the City extra money for additional officer shift.

Balancing resources and a featured amenity.

The City Council has considered the challenges of Blackridge Reservoir on an annual basis: how do we keep an amenity open that we’ve invested money into while reducing headaches at the reservoir and through the surrounding neighborhood? The Council approved a multi-point approach that started May 1, 2024:

  • Implementation of a $15 parking fee—On weekends (not weekdays) and holidays between May 1-September 7, a $15 all-day parking fee will be charged for vehicles accessing Blackridge Reservoir. This fee, administered on-site by a contracted service, Diamond Parking, aims to reduce peak-time crowds, distribute visitors more evenly throughout the week, and help generate revenue to partially support reservoir operations. (approved by the City Council on February 28, 2024)
  • Increased illegal parking fine from $25 to $100— the previous fine of $25 for illegal parking throughout the city has not proven sufficient to deter improperly parked cars, nor come close to covering the costs of issuing and processing the fines. The Council adopted an increased standard fine of $100 with a maximum of $200. Though the issue of illegal parking is concentrated at and near Blackridge Reservoir during peak summer times, it happens throughout the city. Parking regulations are in place to promote safety, including emergency access and clear driver views. (approved by the City Council on March 13, 2024)
  • Pavilion reservations—the large pavilion at Blackridge Reservoir includes several parking spaces as part of a pavilion event reservation. With the new parking day pass at the reservoir, the pavilion reservation charge increased to include the equivalent cost of the parking spaces. (approved by the City Council on February 28, 2024)
  • Signage at the reservoir was re-designed for consistency and clarity. Signs in the surrounding permit-only neighborhoods notes the increased parking fine.
  • Parking permit area—Anticipating a shift in parking patterns due to the proposed fee and fine adjustments, the City proposed expanding the permitted parking area to include more streets to deter people from using the reservoir when it is already full. The petition to expand the area did not gain enough signatures to make a change, so the permit area was not expanded. However, the City eliminated the $25 fee charged to residents to acquire the annual parking permit.
