HomeMy WebLinkAboutSurvey and Drafting StandardsCITY OF RENTON | PERMIT SERVICES SURVEY AND DRAFTING STANDARDS SURVEY STANDARDS All surveys and survey reports shall be prepared under the direct supervision of a professional land surveyor registered under Chapter 18.43 RCW. These documents shall comply with all requirements established by the Board of Registration for Professional Engineers and Land Surveyors pursuant to Chapter 18.43 RCW. Horizontal Control The horizontal component of all surveys shall be based on the North American Datum of 1983/91 (NAD 83/91). Horizontal control for each project must reference, or be connected to, at least two monuments from the City of Renton Survey Control Network. Vertical Control The vertical component of all surveys shall be based on the North American Vertical Datum of 1988 (NAVD 88) and tied to at least one benchmark from the City of Renton Survey Control Network. 1. If two such benchmarks are located within 3,000 feet of the project site, ties to both benchmarks are required. 2. The benchmark(s) used shall be clearly identified on the survey drawing. 3. If no City of Renton benchmark exists within 3,000 feet of the project, a temporary benchmark must be established in a permanent and stable manner near the project site and maintained for the project’s duration. 4. The source of elevations and a description of any benchmarks established shall be shown on the drawing. CORNERS AND MONUMENTS At a point on a land boundary, at the juncture of two or more boundary lines, a monument is usually set at such points to physically reference a corner’s location on the ground. MONUMENT SETTING AND REFERENCING All property or lot corners established or reestablished on a plat or other recorded survey shall be marked with a permanent monument set at the actual corner point. Where setting such monuments is impractical or where they are likely to be disturbed or destroyed (e.g., at the front corners of lots), a witness monument shall be set instead. In most cases, this will consist of extending the lot line to a tack in lead placed in the curb. The relationship between each witness monument and its corresponding corner shall be clearly shown or described on the face of the plat or survey of record — for example: “Tacks in lead on the extensions of the lot side lines have been set in the curbs on the extensions of said lines with the curb.” SURVEY AND DRAFTING STANDARDS rentonwa.gov/permitservices | developmentengineering@rentonwa.gov | 425-430-7240 10/9/2025 Page 2 of 16 AS-BUILT SURVEY All improvements required to have an “as-built” (post-construction) survey under City of Renton Codes, Title 4 – Development Regulations, and Title 9 – Public Ways and Property, shall be located both horizontally and vertically by either a radial survey or a station-offset survey.
