Board of Equalization


If you meet the requirements as outlined in the Board of Equalization policy and want to have your property evaluated, please submit a letter of request to BMID Board of Equalization. This letter may be sent at anytime during the year but must be in the BMID office by November 15th. The Board of Equalization meets once a year at 1pm on the first Wednesday in December.


Any requests for Adjustment of Irrigable Acreages will be evaluated based upon the following criteria:

  • No adjustment will be made on areas of less than ¼ acre.
  • Adjustment based upon slope requires a slope greater than 45%.
  • Adjustment based upon land type e.g. too rocky will be evaluated with respect to the land being unsuitable for grazing or for any crop.
  • Any land previously equalized out of the District, which is later irrigated without advance permission from the District, will be subject to retroactive assessments to the time of equalization and all applicable penalties.

Noted as part of the minutes of the regular board meeting held on February 7, 2001.


Residential Irrigation Policies



A Resolution of the Board of Directors of Badger Mountain Irrigation District establishing the Residential Irrigation Water Distribution Regulations.

  • Watering is encouraged between the hours of 8:00 p.m. and 8:00 a.m. to minimize evaporative losses.
  • Over-watering due to prolonged irrigation, blown sprinkler heads and or leaks should be avoided. Some examples of over-watering are: ponding of water or run-off onto the street. The District recommends that irrigation customers adhere to local best management practices for turf watering. BMID customers are encouraged to seek advice from local soil conservation Districts, WSU Extension Service and local sod companies. If over-watering continues to occur after written notification by BMID, the District reserves the right to terminate the situation by shutting off the service outlet. A $60.00 disconnect/reconnect fee will be charged before service is restored.
  • Every lot must have a distribution box and valve accessible by the District. Valves and equipment within distribution boxes are the property of the District. Irrigation customers are to supply their own emergency shut-off valve somewhere downstream of the District-owned distribution outlet. No person or persons other than District personnel shall operate equipment within the distribution boxes. No changes or alterations are allowed within BMID valve boxes.

Encroachment Policy


1.0  Purpose:

The purpose of this policy is to establish guidelines for the protection of District-owned underground infrastructure.  Specifically, this policy is intended to protect the underground BMID-owned pipe valves, fittings and appurtenances but also the private property through which these easements run by establishing standard dimensions of easements and bury depths (depth of cover) over the pipe distribution systems. (RCW 58.17.310)

2.0  Definitions:

Encroachment is defined as any placement or construction of a permanent structure or excessive excavation or filling on the existing grade within a BMID pipe easement: A permanent structure is defined as a house, garage, shop, tennis court, underground swimming pool, keystone block or structural concrete blocks or walls, underground fish pond/waterfall feature, wood decks, or large structural pergolas requiring embedded treated wood columns. The planting and placement of large trees, shrubs or hedges will also not be allowed within BMID easements without prior approval from the District. Exempt structures or items are defined as City or County Roads, private driveways generally perpendicular to the easement, decorative curbing crossing the easement, corrals and fences and other buried utilities crossing under or over the District’s easement and pipeline.

Easements are defined as narrow strips of land designed and recorded on all lots, blocks or parcels of land that provide for the routing and placement of underground utilities.

All BMID underground pipe, valves, fittings and appurtenances shall be protected on all sides by an easement. Specifically, underground pipe, valves and appurtenances shall be situated horizontally and vertically within either a 10-foot or 20-foot wide easement depending on the size and type of pipe. (See 5.0 below)  An easement allows for the unencumbered ingress and egress of District personnel for the purpose of the operation, maintenance, modification, inspection and repair of these various District-owned assets.

Depth of cover means that distance from the finish grade to the top of pipe. Horizontal dimensions of pipe cover vary according to the diameter and type of pipe. (See Fig. 1).The minimum and maximum depth of cover is defined in Sections 4.0- 5.0.

3.0  Procedure: These standards shall become part of the BMID Standard Construction

Standards for both the Irrigation and Domestic pipe distribution systems.

4.0  Standard Dimensions: Easements / Depth of Cover

All BMID easements are either 10-feet wide or 20-feet wide.

Ten foot wide easements are reserved for sub-main, water distribution piping typically along residential lot lines or within public street right of ways.. Typical pipe sizes within these easements shall be from 1-inch to 12 inch diameter. There are some exceptions were larger diameter pipe is allowed.

Twenty-foot easements are intended for large diameter, high-pressure distribution/transmission mains (typically irrigation).

These distribution mains are high pressure, larger bore pipe ranging in size from 6-inch to 48-inch diameter. Pipe material is welded steel.

Depth of Cover:

The minimum depth of cover over a BMID domestic water line is 4.0 feet. (48 inches)

The minimum depth of cover over a BMID irrigation pipe is 2.5 feet. (30 inches)

The maximum depth of cover for any pipe is 5.0 feet. (60 inches).

The minimum lateral distances (protective pipe envelope) of backfill for each pipe is shown in Figure 1.  These distances are measured from the point of tangency from the outside of the pipe wall.

Note:  Minimum depth of cover underneath street varies according to jurisdiction. (City of Richland or Benton County Public Works)
