Setback requirements of a side, rear or front yard of any zoning lot bordering on a lake shall be determined by the ordinary high water line of the lake adjacent to the side, rear or front of a building to be constructed; provided, that this shall not be construed as decreasing or modifying state or county health regulations relating to the installation of improvements in proximity to sources of public water or bodies of water. 25 Repealed by Ord. 888. 26 See Chapter 18.100 NPMC for additional requirements. 27 Structures with street level dwelling units must be set back a minimum of 10 feet. 28 Ten feet of the required setback shall include evergreen plantings, be kept free of weeds, and pruned in a manner that a reasonably proud owner would maintain such planting or shrubbery on residence property. 29 Side yard setback for multifamily development in mixed use zone is 10 feet. 30 See NPMC 18.32.080(2). 31 See NPMC 18.24.020. 32 The ridge of pitched roofs with a minimum slope of three to twelve (3:12) may extend up to 35 feet. Additional height bonus is allowed by using the transfer of development rights as provided in Chapter 18.82 NPMC. 33 Additional height bonus is allowed by using the transfer of development rights as provided in Chapter 18.82 NPMC. 34 The ridge of pitched roofs with a minimum slope of three to twelve (3:12) may extend up to 45 feet. 35 See Chapter 18.100 NPMC for site design and open space requirements. 36 See NPMC 18.15.030. 37 Lot coverage includes all buildings, accessory buildings and structures but not private swimming pools or open area used to provide parking. 38 Additional density or intensity is allowed by using the transfer of development rights as provided in Chapter 18.82 NPMC. |

18.15.025 Surveys and topographic maps.
(1) Topographic maps submitted for the purpose of establishing natural elevation (NPMC 18.08.140), building height (NPMC 18.08.080), and presubdivision contours (NPMC 17.20.020(9)) shall be furnished at the property owner’s or applicant’s expense, and shall be prepared by a professional land surveyor licensed in the state of Washington. A benchmark shall be noted on all information supplied for the purpose of establishing a field reference. The benchmark shall, when practical, be located on city property. In cases where, at a required point of measurement, the topography lines and building outline do not intersect, spot elevations for the natural grade shall be indicated on the topographical map.
(2) Where the change in elevation of the lot is less than 15 feet in a horizontal distance of 100 feet within the proposed building lot, applicants may forego a full topographical map but must submit, at a minimum, a map indicating all elevations necessary to determine building heights, fills, and any grading activity. (Ord. 939 § 3, 2016).
18.15.030 Gross floor area ratio for NC and MU zones.
(1) The gross floor area ratios set forth in Chart 18.15.032 apply to all development in the neighborhood commercial (NC) and mixed use (MU) zones.
(2) To determine the allowed gross floor area of all structures on a site, the gross floor area ratio (GFAR) in Chart 18.15.032 is multiplied by the area of the lot. (Ord. 989 § 4, 2019; Ord. 888 § 2 (Exh. A), 2012; Ord. 743 § 2, 2004).

(3) Buildings at the corners of public rights-of-way and/or private travelways shall have a primary building facade on both streets and/or travelways and at least 75 percent of each primary building facade shall be set to a line no farther than two feet from either the public right-of-way or private travelway.
