Zoning Administrator Resolution No. ZA2019-021 <br />Paqe 3 of 9 <br />2. The neighborhood is predominantly developed with two- and three-story single-family <br />residences. The proposed design, bulk, and scale of the development will be consistent <br />with the existing neighborhood pattern of development and expected future <br />development. <br />3. Pursuant to NBMC Section 21.30.030(C)(3)(i)(iv), the property owner will be required to <br />enter into an agreement with the City waiving any potential right to protection to address <br />situations in the future in which the development is threatened with damage or destruction <br />by coastal hazards (e.g., waves, erosion, and sea level rise). The property owner will also <br />be required to acknowledge any hazards present at the site and unconditionally waive any <br />claim to damage or liability against the decision authority, consistent with NBMC Section <br />21.30.015(D)(3)(c). Both requirements are included as conditions of approval that will need <br />to be satisfied prior to the issuance of building permits for construction. <br />4. The finished floor elevation of the first floor of the proposed structure is 11.5 feet <br />(NAVD88), which complies with the minimum 9.0 -foot (NAVD88) elevation standard for <br />new structures. A project -specific Coastal Hazards Report and Sea Level Rise Analysis <br />was prepared by GeoSoils, Inc., dated February 5, 2019. The report concludes that the <br />highest high tide elevation (currently 7.5 feet NAVD88) will not exceed the proposed <br />finished floor elevation of 11.5 feet NAVD88 using the low-rise aversion projected sea <br />level rise (2.9 -foot increase) over the 75 -year design life of the structure based on <br />estimates for sea level rise provided by the State of California Sea -Level Rise Guidance <br />2018. <br />5. Pursuant to NBMC Section 21.35.050 (Water Quality and Hydrology Plan), because of the <br />project site's proximity to coastal waters, a Water Quality and Hydrology Plan (WQHP) will <br />undergo a final review during building permit plan check. The WQHP includes a polluted <br />runoff and hydrologic site characterization, a sizing standard for Best Management <br />Practices (BMPs), use of a low -impact development design approach to retain the storm <br />runoff volume on site, and documentation of the expected effectiveness of the proposed <br />BMPs. Construction plans will be reviewed for compliance with the approved WQHP prior <br />to building permit issuance. <br />6. The property is located in an area known for the potential of seismic activity and <br />liquefaction. All projects are required to comply with the California Building Code (CBC) <br />and Building Division standards and policies. Geotechnical investigations specifically <br />addressing liquefaction are required to be reviewed and approved prior to the issuance of <br />building permits. Permit issuance is also contingent on the inclusion of design mitigation <br />identified in the investigations. Construction plans are reviewed for compliance with <br />approved investigations and the CBC prior to building permit issuance. <br />7. A post -construction drainage system will be installed that includes drainage and <br />percolation features designed to retain dry weather and minor rain runoff on-site to ensure <br />the project does not impact water quality. Any water not retained on-site is directed to the <br />City's storm drain system. <br />
