Street Sweeping

Streets in Sandy are swept monthly. Please help keep your street clean by moving your car off the street when the sweeper comes through. See the map below for details.

Tree Planting

Trees can be used to mitigate for ground-level impervious surfaces due to their ability to intercept stormwater and allow it to evaporate, as well as dissipating the energy of runoff.  They also provide shade, which helps keep surface temperatures lower, and they facilitate stormwater infiltration and groundwater recharge.

Vegetated Infiltration Basins

A vegetated infiltration basin is a landscaped depression that accepts stormwater runoff from impervious surfaces, and is similar to a planter box.  The basins allow pollutants to settle and filter out, and also provide the opportunity for infiltration.  A vegetated infiltration basin can help fulfill site landscaping requirements.

Vegetated Swale Maintenance Requirements

As needed

  • Remove any debris or garbage that is caught in the swale
  • Clear the inlet(s) and outlet(s) to allow for proper flow dispersal
  • Inspect and repair damaged inlet erosion control devices and check dams
  • Water plants as needed until established
  • Remove sediment build-up, determine source of sediment, and take measures to prevent it from re-entering the facility
  • Take appropriate pest control measures if insects or rodents are inhabiting the swale

Seasonally

    Vegetated Swale Planting Specifications

    The minimum plant material quantities per 100 square feet of facility area are:

    Vegetated Swale Specifications

    Swales with a gentle slope (less than 4% average) are the most effective at treating stormwater.  The maximum slope must be less than 6%.  Facility storage depth may range from 2 to 12 inches.  A freeboard (6 to 12 inches) may be required if the adjacent area would be damaged by flooding.  Maximum side slopes are 3 horizontal to 1 vertical; slopes and depths should be minimized to the extent practical for aesthetic and safety reasons.

    How can I share my feedback with the City Council?

    The Sandy City Council always welcomes comments and feedback from residents.  City Council meetings are open to the public, and each meeting includes a public comment period where anyone can address the Council (typically for 3 minutes each).  Meeting information is available at https://sandy.civicweb.net/portal/.  If you have a letter or email you would like to be considered by the Council at one of its meetings, send it to

    What about all the new houses - will developers pay their fair share?

    In addition to the monthly fee increases, new commercial and residential development projects will pay their fair share for the required sewer investments. System Development Charges, which are paid by new development, were increased from $1,834 to $4,889 for each new home in 2020, and are proposed to increase to $5,157 in 2021.  View the Wastewater System Improvements page.

    How can I be sure utility revenue will be spent appropriately by the City?

    It is important to know that per state law, wastewater rate revenue must only be used on the city’s wastewater utility. The revenue raised by the wastewater rate increase will be used to pay for the principal and interest on loans and special financing for the wastewater system improvements. The city is financially audited on an annual basis to ensure laws are followed and dollars are spent legally and appropriately.  View the publicly available audit results.
