ATTY/RESO.0012/PC RESO GRANTING APPROVAL OF AN ARC PERMIT FOR 240 TWIN DOLPHIN DR <br />REV: 03-11-2021 PR <br />Page 16 of 21 <br />52. Parking Garage Ramps - Parking garage ramps shall meet the Design Criteria of the Engineering Standards and consider safety and visibility of pedestrians to the satisfaction of the City Engineer. Access controls shall be designed and placed in such a way that vehicles do not block the public sidewalk or queue in the public right-of-way. The access control system shall be delineated in the building permit submittal. Person doors with panic hardware and alarms shall be installed at or adjacent to gates between private and public parking to allow the safest emergency egress path of travel. [SDR][ENGINEERING] 53. Shoring for Excavations – No tiebacks shall extend into the public right of way or onto adjacent properties without the written agreement of the City and/or private property owner. Any tie-backs within the City’s right of way shall be de-tensioned prior to permit sign-off and/or project acceptance. [COA] [ENGINEERING] Fire and Safety 54. Roof Deck - As this project is proposing to have a large occupied roof deck on the sixth floor, the height of the building exceeds 75 feet above the lowest level of fire department vehicular access and therefore shall comply with Section 403 of the 2019 California Building Code and have all of the required high-rise features incorporated into the building’s design. [COA ][FIRE] 55. Roof Occupant Load – The current plan submission lists the square footage of the roof deck as 8160 square feet. At a concentrated use factor of seven square feet per person, the occupancy of the roof deck is calculated out to be 1166 persons. This occupant load will require four exit stairs. The plans indicate only two stairwells in the central core area of the building. If the use factor used to calculate the occupant load is a less concentrated use factor of 15, the occupant load calculates to 544 which would require three exit stairs as per Table 1006.3.2 of the 2019 CFC. Changes to the occupancy of the roof deck will require additional analysis during the building permit plan review. At building permit submittal, provide plans with detailed documentation of the proposed use of the roof deck to determine the correct number of exits required, the required exiting widths, and the travel distances to the exits to show compliance with Fire Code. [COA][FIRE] 56. Exiting Analysis - Provide a detailed exiting analysis for the entire building that indicates the occupant loading for all floors, the number and widths of exits, and the travel distances to access the exits from all points within the building. [COA][FIRE] 57. Emergency Responder Radio Communications System – The project is required to have an Emergency Responder Radio Communications System (ERRCS) installed in accordance with CFC 510, NFPA 1221 NFPA 72, and the CEC. The system needs to be a single campus wide system with one set of bi-directional amplifiers with coverage extended into all levels of the building and the garage. Signal distribution between buildings is typically accomplished with fiber optic cables. [COA][FIRE] 58. Fire Department Knox Building Access – Knox Key boxes are required as part of this project to allow emergency access for firefighters to all buildings. Indicate on the plans that Knox Key boxes will be provided at the entrances to all buildings at locations approved by the Fire Department. Recessed key boxes shall be installed at all buildings five to six feet above finished grade. Any electric gates shall have Knox Key Switches installed as per CFC 506. [SDR – CFC 506][FIRE]
