Public Records Requests

WHP Program staff have developed a database to provide a central repository for groundwater-related data. Staff gathered data including: sampling location, ground and surface water elevation, chemical analysis, temperature and pH from both public and privately-owned sites.  These sites include the City’s groundwater monitoring network, municipal supply wells and privately-owned monitoring sites.

The database is used to fulfill public records requests, a crucial component of the WHP Program.  Staff can reply to the many requests they receive, providing maps of the monitoring points in each project area as well as Excel files containing water-related information. The data can be used to determine the best time of the year to conduct underground work (during the dry season), whether temporary dewatering is necessary or if plans for development need to be adjusted due to consistent high water levels.

Consultants and developers can also obtain information necessary to fulfill requirements of critical areas reporting using the public records request process. Critical Areas Reports are required for all proposed development activities located in the CARA.

You may be able to find the information you need here. WHP Program staff have developed:
  1. A contour map that shows the estimated shallowest depth to groundwater in the Bear Creek and Sammamish River valleys in Redmond. Please review the depth-to-groundwater map.
  2. Winter and summer water level elevation contour maps of the CARA. Please review the January 2013 groundwater elevation map. Please review the July 2013 groundwater elevation map.
  3. Continuous monitoring water level elevation data at numerous locations throughout the CARA. Please review a map showing the locations where data are available. View time series graphs.

Resources to Minimize Fiscal and Environmental Liability

Businesses can help keep Redmond safe, healthy and clean by evaluating their hazardous material handling process today. In an effort to protect our fragile drinking water aquifer and streams, the Wellhead Protection Program recommends all business within the City of Redmond regardless of Wellhead Protection Zone designation follow these guidelines:
  • Reducing the amount of waste you produce and store reduces your potential liability and cost.
  • For proper waste disposal refer to the Local Hazardous Waste Management Program (LHWMP) in King County.
  • Small businesses may qualify to take part in LHWMP’s Pilot Project to dispose of hazardous waste at Household Hazardous Waste Facilities in King County.
  • The City of Redmond, in partnership with King County’s Local Hazardous Waste Management Program (LHWMP) is participating in the Voucher Incentive Program. This program offers small businesses 50 percent matching funds (up to $500) to manage, dispose of, reduce or recycle hazardous waste.
  • Oil/water separators are not designed to manage spilled hazardous materials.
  • Incompatible substances: Substances that produce heat, pressure, fire, violent reaction or toxic fumes and gases when mixed are considered incompatible. Do not put material into a container that previously held an incompatible substance.
  • Fire hazards: Ignitable/flammable wastes have a flash point of less than 140 degrees F. You may need special flammable storage lockers for these materials. For detailed information on these wastes, refer to WAC 173-303-090 and your local fire department or district.
  • Local codes: All businesses that use hazardous materials should be aware of local fire codes. There may be additional fire, storm water, or other local and city ordinances that apply to you. Contact the appropriate agencies.
