Applications for preliminary plat approval shall contain all of the following information:
(A) Application for quasi-judicial review. Application materials for a quasi-judicial review, including application form, fee, narrative, and plan exhibits, are required. See § 151.233.
(B) Public facilities and services impact analysis. The impact analysis shall quantify and assess the effects of the proposed development on public facilities and services. The City Engineer and City Planning Official shall advise as to the scope of the study, which shall address, at a minimum, the transportation system, including required improvements for vehicles and pedestrians; the drainage system; the parks system (for subdivisions and master planned developments); water system; and sewer system. For each system and type of impact, the analysis shall propose improvements necessary to meet the City Public Works Design Standards Manual, other applicable adopted ordinances and facility master plans. The city may require a separate traffic impact analysis.
(C) Preliminary plat map(s). An engineer or professional land surveyor licensed by the State of Oregon shall prepare the preliminary plat map(s), at a scale determined by the City Engineer, which shall consist of at least the following information:
(1) Name of proposed partition or subdivision (partitions are named by year and file number). This name shall not duplicate the name of another land division in Washington County (check with County Surveyor);
(2) Date, north arrow, and scale of drawing;
(3) Location of the development sufficient to define its location in the city, boundaries, and a legal description of the site;
(4) Zoning of parcel to be divided, including any overlay zones; and
(5) A title block including the names, addresses and telephone numbers of the owners of the subject property and, as applicable, the name of the engineer and surveyor, and the date of the survey;
(6) Identification of the drawing as a "preliminary plat"; and
(7) Existing conditions. Except where the City Planning Official deems certain information is not relevant, applications for preliminary plat approval shall contain all of the following information on existing conditions of the site:
(a) Streets. Location, name, and present width of all streets, alleys and rights-of-way on and abutting the site;
(b) Easements. Width, location and purpose of all existing easements of record on and abutting the site;
(c) Utilities. Location and identity of all utilities on and abutting the site. If water mains and sewers are not on or abutting the site, indicate the direction and distance to the nearest one and show how utilities will be brought to standards;
(d) Ground elevations shown by contour lines at 2-foot vertical interval. Such ground elevations shall be related to some established benchmark or other datum approved by the County Surveyor; the Planning Commission may waive this standard for partitions when grades, on average, are less than 6%;
(e) The location and elevation of the closest benchmark(s) within or adjacent to the site (i.e., for surveying purposes);
(f) The base flood elevation, per FEMA Flood Insurance Rate Maps, as applicable;
(g) North arrow and scale; and
(h) Other information, as deemed necessary by the City Planning Official for review of the application. The city may require studies or exhibits prepared by qualified professionals to address specific site features and code requirements.
(8) Proposed development (may be depicted on more than 1 map). Except where the City Planning Official deems certain information is not relevant, applications for preliminary plat approval shall contain all of the following information on the proposed development:
(a) Proposed lots, streets, tracts, including private open space, common area, or streets, if any, and approximate dimensions, area calculation (e.g., in square feet), and identification numbers for all proposed lots and tracts;
(b) Location, names, right-of-way dimensions, approximate radius of street curves, and approximate finished street center line grades;
(c) Any streets and tracts that are being held for private use and all reservations and restrictions relating to such private tracts shall be identified;
(d) The Planning Commission shall also require a dedication of land for public park and recreation purposes. The public park dedication shall not exceed 15% (0 to 15%) of the buildable land area within the subdivision;
(e) Easements: location, width and purpose of all proposed easements;
(f) Proposed uses of the property, including all areas proposed to be dedicated as public right-of-way or reserved as open space for the purpose of surface water management, recreation, or other use;
(g) Proposed public street improvements, consistent with the Public Works Design Standards Manual, including evidence of contact with the applicable road authority, if different than the city, where a new street connection is proposed;
(h) On slopes exceeding an average grade of 10%, as determined by the City Engineer, the preliminary location of development on lots (e.g., building envelopes), demonstrating that future development can meet minimum required setbacks and applicable engineering design standards for streets, driveways, drainage, and retaining walls, as applicable;
(i) Preliminary design for extending city water service to each lot consistent with the Public Works Design Standards Manual;
(j) Preliminary design for extending sanitary sewer service to each lot, and a Service Provider Letter from Clean Water Services;
(k) Proposed method of storm water drainage and treatment, if required, consistent with the Public Works Design Standards Manual and a Service Provider Letter from Clean Water Services;
(l) The approximate location and identity of other utilities, consistent with the Public Works Design Standards Manual including the locations of street lighting fixtures, as applicable;
(m) Evidence of compliance with applicable overlay zones, including but not limited to those regulating development in flood hazard areas.
