Boundary Line Adjustment
A Boundary Line Adjustment is an application made for the purpose of adjusting boundary lines between platted or unplatted lots, or both, and/or accommodates a transfer of land between adjacent separate lots which does not create any additional lots, tracts, parcels, or building sites, nor create existing lots which are more nonconforming. A boundary line adjustment plan is a civil plan that shows all existing site improvements and encumbrances such as all structures, eaves, fences, accessory structures, easements, street improvements and other site development. This plan needs to show the existing boundary line and the proposed boundary lines of the lots that are changing and how they will meet all required development standards. The surveyor is responsible for verifying and accurately depicting the location and dimensions of property lines, rights-of-way, and easements.
A Boundary Line Adjustment is defined as a Land Boundary Survey (W.A.C. 332-130) and must be prepared by a professional land surveyor registered in the State of Washington, using these standards:
1. All land surveys submitted shall state on the mapping – Washington State Coordinate System NAD83 (2011) – North Zone and noted accordingly as the Horizontal Datum.
2. The adjusted boundary line shall be monumented and tied to at least two (2) City of Bellevue Survey Control Network monuments. Survey Control Data Cards are available on-line, or from the survey staff (425-452-5263).
3. Boundary Line Adjustment drawings must be prepared on the City of Bellevue drawing title block. AutoCAD compatible drawing files are available on-line, or from the survey staff (425-452-6018). For additional Land Survey support Land Survey | City of Bellevue
A Boundary Line Adjustment is a recorded survey and must comply with all requirements of R.C.W. 58.09 (Survey Recording Act) and W.A.C. 332-130-050 (Survey Map Requirements). The following additional items must be included:
A. Legal description(s) of the parcels to be adjusted, verbatim from a current title report.
B. All existing lots, tracts, parcels, right-of-ways, and easements shown in light or medium line weights using various dashed line types.
C. Recording numbers and brief description of any easements, maintenance agreements, covenants, restrictions, etc. affecting the subject property.
D. Final lots shown with heavy line weights and solid lines, with lot designations and areas in square feet.
E. Clearly label lines subject to being adjusted as New Line, Old Line or Line To Be Removed (in the case of lot combination).
F. Sufficient geometry (bearings and distances) to accurately locate all lots, tracts, parcels, and easements.
G. All existing structures with their locations indicated by measurements perpendicular to the adjusted property lines. If existing structures are to be retained development standards including lot coverage, impervious surface, hardscape, greenscape, and FAR calculations shall be provided.
H. Owner’s Declaration signed and acknowledged before a notary public by all parties having any ownership interest in the lands to be adjusted. All stamps and signatures must be in permanent black ink.
The Boundary Line Adjustment plan may include, but is not limited to, the following items:
- North Arrow and graphic scale
- Surveyor’s Seal and Standard Certificate on all pages (Name, license number, address, signature, date).
- County Auditor’s recording certificate.
- Owner(s) signature block(s) – signatures must be in black ink.
- Notary’s seal and signature, certifying owner(s) – signatures must be in black ink.
- Approval signature blocks for Development Services (Land Use Planning), Utilities, Transportation, and City Surveyor.
- Permit number.
- Title block: Name of Surveyor or Firm performing survey, contact information of the preparer, sheet identification number, and date prepared or revised.
- Subdivision index (1/4, 1/4 Section, Township, Range number)
- Existing City of Bellevue zoning district.
- Setback dimensions required by the zoning district.
- Found corners and/or rebar per referenced survey on map (if applicable); and
- Existing or proposed restrictions on use of the land, including critical areas and buffers.
A Boundary Line Adjustment plan moves a property line between two lots, allowing for the exchange of land between adjoining lots. It can also combine multiple lots into a single lot. A Boundary Line Adjustment cannot create an additional building lot and cannot result in a lot that does not comply with the Land Use Code (LUC).
Preliminary Short Plat & Plat
Short Plat: The map or representation of a subdivision of nine parcels or less.
Plat: The map or representation of a subdivision of ten parcels or more.
A preliminary short plat or plat is the first stage of the subdivision process and must be approved before a final short plat or plat can be recorded. The preliminary short plat and plat should show all existing and proposed site improvements and encumbrances such as all streets, driveways, covenants, structures, eaves, fences, accessory structures, easements, trees, street improvements, and other site development. This plan needs to show how the proposed short platting will meet all required development standards.
The Preliminary Short Plat and Plat drawing requirements should include, but is not limited to, the following:
1. The Boundary & Topographic Survey (see separate requirements) depicts existing site conditions. Use the survey as the underlying base map for the Preliminary Plat.
2. Proposed name of plat (short plats excluded) must be approved by King County Department of Records and Elections.
3. Provide the following information:
a. Name, address, and phone number of the developer and of each property owner.
b. Name, address, phone number, signature, and seal of the professional land surveyor who prepared the plat.
c. Quarter section(s), township, and range.
d. Vicinity map, north arrow, and graphic scale.
e. Legal description(s) of the property to be subdivided, verbatim from the Title Report/Plat Certificate.
f. All existing lots, tracts, parcels, rights-of-way, and easements with names, dimensions, and recording numbers within 100 feet of the perimeter of the proposed plat.
g. Depiction of any contiguous land in which there is an interest by reason of ownership, contract for purchase, earnest money agreement, or option by any person, firm, or corporation in any manner connected with the development or applicant(s).
h. Sufficient geometry to accurately locate all proposed lots, tracts, parcels and easements, with lot designations and area in square feet.
I. Proposed rights-of-way and any proposed ingress, egress, utility, open space, drainage, native growth protection easements, and tracts, including critical areas and buffers. Designate proposed roads as "Road A," "Road B," etc. Designate proposed tracts as "Tract A," "Tract B," etc.
j. Specific identification of the intended use and ownership for each auxiliary tract or easement.
