CHAPTER 17
18A OBR DISTRICT I
§ 17.18A.010 Purpose, management objectives and jurisdiction.
(1)
Purpose. The Ocean Beach residential I zone exists within the urban shoreline and is intended to preserve the natural systems, processes, and amenities which maintain the unique character of the coast and attract people to this area, and to provide for low density residential development in the upland area. The area within the Ocean Beach environment will be maintained in its natural state to as great an extent as possible consistent with the requirements of this chapter.
(2)
Management Objectives. To preserve and protect the beach, dune and upland areas associated with the Pacific Ocean while accommodating residential and recreational uses.
(3)
Jurisdiction. The Ocean Beach residential I zone is measured to the point of land lying eastward of the primary dune system incorporating the interdunal deflation plain up to the toe of the secondary dune system, which is referred to as the "shoreland jurisdiction boundary." The city and Washington Department of Ecology shall maintain a map showing the location of the line. Such line may be modified by specific on-site delineation approved by the Washington Department of Ecology and the city and as defined by the most recent map available.

§ 17.18A.080 Maximum height limits.
Maximum height limits and the method of measuring height for the areas west of Surf Street and south of Ocean Avenue:
(1)
Maximum Height. The maximum height of any building or structure shall not exceed a total maximum height of 30 feet. Accessory buildings and structures shall not exceed a maximum height of 15 feet. This requirement applies to all areas described in this section, notwithstanding any provision of the zoning district within which the property is located.
(2)
Measurement of Maximum Height. All building and structure heights shall be measured as set out in the following definitions and Figures 17.18A(1) and (2). The maximum building height permitted in the areas west of Surf Street and south of Ocean Avenue shall be determined based on these definitions and Figures 17.18A(1) and (2). The definitions of "building height" and "grade" in WMC § 17.08.020, Definitions, shall not apply to the OBR I zone.
(A)
"Average finished grade level"
means the average of the topography of the portion of the lot, parcel, or tract of real property which will be directly under the proposed building or structure as that topography will exist after the building or structure is constructed and the property filled, graded, and/or excavated, and landscaped; provided, that in the case of structures to be built over water, average grade level shall be the elevation of ordinary high water. Calculation of the average grade level shall be made by averaging the elevations at the center of all exterior walls of the proposed building or structure. (See Figure 17.18A(1)).
(B)
"Average natural grade level"
means the average of the natural or existing topography of the portion of the lot, parcel or tract of real property which will be directly under the proposed building or structure; provided, that in the case of structures to be built over water, average grade level shall be the elevation of ordinary high water. Calculation of the average grade level shall be made by averaging the elevations at the center of all exterior walls of the proposed building or structure. (See Figure 17.18A(1)).
(C)
"Height"
means the maximum vertical dimension of a structure, which for the purposes of this section shall be the greater of the two vertical dimensions obtained by the following methods of measuring height:
(i)
Method A. The vertical distance measured from the average natural grade level to the highest ledge or coping on a mansard or flat roof, or the highest ridge of a pitch, shed, or hip roof. (See Figure 17.18A(2)).
(ii)
Method B. The vertical distance measured from the average finished grade level to the highest edge or coping on a mansard or flat roof, or the highest ridge of a pitch, shed or hip roof. (See Figure 17.18A(2)).
