17.36.104    APPLICATION--LOT LAYOUT DOCUMENT

(1) The applicant shall provide four copies of lot layout documents for the proposed subdivision. The lot layout documents must be on sheets no larger than 11" x 17", at a scale no smaller than 1" = 200'. The reviewing authority may require a larger scale if needed to enhance readability. Multiple sheets may be used for large developments, provided that individual lots are not split across two sheets. If multiple sheets are used, a single sheet must also be provided, using an appropriate scale, that shows the entire development.

(2) The following information must be provided on the lot layout documents. Other information (e.g., percolation test results, soil profile descriptions) may be included on the lot layout documents only if the documents remain legible:

(a) the name of the subdivision, and the county, section, township and range (e.g., "Sec. 12 T27N R6E") in which the proposed subdivision is located;

(b) a north arrow and scale;

(c) the boundaries, dimensions, and total area of each lot;

(d) an identifier or number for each lot (e.g., "Lot 1, Lot 2," "Tract 1, Tract 2," or "Parcel 1, Parcel 2");

(e) locations of existing and proposed easements;

(f) locations of existing and proposed roads and utilities;

(g) locations, sizes, and design details of existing and proposed storm water structures (culverts, ponds, dry wells, etc.);

(h) locations of drainageways;

(i) name and affiliation of the person who prepared the lot layout;

(j) information as set out in Table 1 for the specific water supply and wastewater systems in the subdivision. All systems must be labeled as "existing" or "proposed."
