Subchapter G Flood-resistant Construction

   (a)   Scope. This rule provides application submission requirements for alterations to structures located in areas of special flood hazard, provides the method for determining the market value of a structure, and provides the method for determining whether repairs, reconstructions, rehabilitations, additions or improvements constitute a substantial improvement.
   (b)   References. See Section BC G201.2 (definitions of market value of structure, substantial damage, and substantial improvement) and §28-104.7.11.
   (c)   Applicant's statement. Applicants shall include in every alteration application the statement: "Work proposed in this application (is/is not) included in a substantial improvement as defined by Section BC G201.2 and 1 RCNY §3606-01."
   (d)   Calculation of market value. To determine the market value of a structure, the applicant shall use either of the two calculation methods below:
      (1)   Assessment roll option. Applicants shall utilize dollar amounts provided by the Department of Finance's most recent "Final Assessment Roll" by multiplying the total market value by the ratio (market value of structure to total market value):
 
 
Market Value of Structure
=
Estimated Market Value (Total)
×
Actual AV (Total) - Actual AV (Land)
Actual AV (Total)
(See Example 1)
or
Market Value of Structure
=
Estimated Market Value (Total)
×
6-20% Limitation (Total) - 6-20% Limitation (Land)
6-20% Limitation (Total)
(See Example 2)
or
Market Value of Structure
=
Estimated Market Value (Total)
×
8-30% Limitation (Total) - 8-30% Limitation (Land)
8-30% Limitation (Total)
(See Example 3)
 
or, at the option of the owner, or where the assessment roll method would not reflect the market value of structure because more than one building occupies a single tax lot,
      (2)   Appraisal option. Applicants shall utilize dollar amounts obtained from an appraisal performed by a New York State licensed Real Estate Appraiser and performed within one year of the filing of the alteration application:
 
 
Market Value of Structure
=
Appraised Market Value (Land and Structure)
=
Appraised Market Value (Land)
 
   (e)   Calculation of cost. To determine the cost of repairs, reconstructions, rehabilitations, additions or improvements of a building or structure, the applicant shall add together:
      (1)   The costs for the given application, regardless of the time it takes to complete the work, plus
      (2)   The cost of all other work to be performed during the same period, including work filed under separate application(s) and including any minor alterations and ordinary repairs.
   (f)   Determination of substantial improvement. Work shall be deemed a substantial improvement if the cost as calculated in paragraph (e) equals or exceeds 50% of the market value of structure as calculated in paragraph (d). A substantial improvement shall also include work performed to a structure that has sustained substantial damage, as such term is defined in Section BC G201.2. In determining whether a structure has sustained substantial damage, the market value shall be calculated in accordance with paragraph (d) of this rule.
   (g)   Application for construction document approval. For an alteration that is not a substantial improvement with a cost exceeding the greater of (1) $40,000 or (2) 25% of the market value of the structure as calculated in subdivision (d) of this section, the applicant shall include calculations of the market value of the structure and costs as outlined in this rule, and shall include any relevant backup documentation including either the online printout of the Department of Finance Final Assessment Roll or a copy of the real estate appraisal.
   (h)   Examples of calculation of market value. The Assessment Information for the following examples is based on information from the Final Assessment Roll as provided by the Department of Finance.
      (1)   Example 1; Actual A/V. For the purposes of this example, the assessed values for both the land and the total for the property are indicated as follows:

(Am. eff. 7/30/2015)
   (a)   Scope. This section establishes procedures for processing letters of map change, including Letters of Map Amendment and Letters of Map Revision based on Fill.
   (b)   References. See §§ BC G102.3, G106.5, and G201.2 (definitions of letter of map amendment (LOMA) and letter of map revision based on fill (LOMR-F)) and §28-104.7.11.
   (c)   Letters of Map Amendment (LOMAs). Where the FEMA FIRMs 360497 indicate that a tax lot or structure is located within an area of special flood hazard, but the owner has obtained an approved LOMA from FEMA removing such tax lot or structure from areas of special flood hazard, the applicant shall nonetheless indicate on the application for construction document approval that the work is located within an area of special flood hazard. However, the work need not conform to the requirements of Appendix G of the Building Code provided (i) the applicant submits the approved LOMA with the application for construction document approval and (ii) the proposed work does not alter the grades on the site to be lower than those elevations specified in the LOMA. The examiner shall waive any required items relating to flood zones. Certificates of occupancy shall comply with Section BC G106.5.
   (d)   Letters of Map Revisions based on Fill (LOMR-Fs). The following procedures shall be followed where the owner requests that the Department sign a FEMA "Community Acknowledgment Form" in support of an application to FEMA for a LOMR-F (see 44 C.F.R. § 65.5). In no case shall fill be placed so as to raise the level of grade higher than curb level within a required yard or rear yard equivalent (see Zoning Resolution §§23-42, 33-22, and 43-22). The applicant shall undertake the following steps in the following order:
      (1)   Submit application for construction document approval. Work to re-grade a site in an A-Zone in order to remove land from an area of special flood hazard shall be performed pursuant to a work permit issued by the Department. Such work shall be allowed as either a separate earthwork application or as part of a new building or alteration application. The application for construction document approval shall include (i) through (v) below:
         (i)   The check-off in the box on the application that the work is located in an area of special flood hazard;
         (ii)   An "Initial Survey" of existing conditions showing 1'-0" contour lines;
         (iii)   No fewer than three sections traversing the entire parcel showing the base flood elevation, any proposed structures (including elevation of lowest floor), required yards and rear yard equivalents, levels of existing natural grade, levels of grade to be removed, final levels of compacted fill, and final levels of uncompacted topsoil. Additional sections shall be required when necessary to adequately depict that the work proposed complies with the code. All levels shall be indicated in NGVD with borough datum in parentheses;
         (iv)   An "Initial LOMR-F Flood Zone Certification" by the registered design professional who is the applicant, stating:
            "In accordance with FEMA's Technical Bulletin 10-01 and in accordance with accepted professional practice, I, ________, certify that the design for the aforementioned development is reasonably safe from flooding and that the design of the development will not increase the risk of flooding to surrounding areas. Additionally, I certify that the design complies with the requirements of Appendix G of the Building Code, and that the level of compacted fill adjacent to all structures in the development, exclusive of uncompacted topsoil, is proposed to be at or above the base flood elevation. Further, I certify that no fill is proposed to be placed in the regulatory floodway or in an area designated as a V-Zone. Further I certify that all applicable Federal, State, and local laws shall be complied with, and all Federal, State, and local permits required for the proposed work have been obtained and submitted into the folder for this job" and
         (v)   Identification of special inspection for fill placement and of evaluation of in-place density in accordance with Sections BC 1704.7.2 and 1704.7.3 (to be certified prior to sign-off). Compaction standards shall be as referenced in FEMA Technical Bulletin 10-01.
      (2)   Obtain approval of construction documents.
      (3)   Submit application to FEMA for Conditional LOMR-F (CLOMR-F) (optional). While the CLOMR-F is an optional step, it provides preconstruction assurance that FEMA will approve the Final LOMR-F if constructed in accordance with the approved plans. At any time after construction document approval, the applicant may present to the Borough Commissioner for the Borough Commissioner's review and signature a FEMA "Community Acknowledgement Form" (which shall indicate "Conditional LOMR-F" in the "Community Comments" section), along with the approved construction documents. The owner may submit this signed Community Acknowledgement Form to FEMA. If the owner elects not to undertake the actions specified in this paragraph three, the owner must nonetheless follow the procedures and take the actions specified in paragraphs four through eight of this subdivision, however, in such case, there will be no preconstruction assurance that FEMA will ultimately approve the Final LOMR-F.
      (4)   Obtain work permit.
      (5)   Complete all grading, fill, and foundation work.
      (6)   Present Community Acknowledgement Form to Borough Commissioner. After the completion of all grading, fill and foundation work, the applicant shall present to the Borough Commissioner for review and signature a FEMA Community Acknowledgement Form, along with the approved plans and following list of additional required items:
         (i)   A "Final Survey" of completed conditions showing 1'-0" contour lines;
         (ii)   Certification of completion for the special inspections for fill placement and of evaluation of in-place density. Compaction standards shall be as referenced in FEMA Technical Bulletin 10-01; and
         (iii)   A "Final LOMR-F Flood Zone Certification" by the registered architect or professional engineer who is the applicant on the PW-1, stating:
"In accordance with FEMA's Technical Bulletin 10-01 and in accordance with accepted professional practice, I, __________________________ , certify that all grading, fill and foundation work is complete, that the design for and construction of the aforementioned development is reasonably safe from flooding and that the design for and construction of the development will not increase the risk of flooding to surrounding areas. I have thoroughly reviewed the annexed "Initial Survey", "Final Survey" and the special inspection reports for fill placement and evaluation of in-place density. Further, I certify that all the work complies with the requirements of Appendix G of the Building Code, and that the level of compacted fill adjacent to all structures in the development, exclusive of uncompacted topsoil, is at or above the base flood elevation. Additionally, I certify that no fill has been placed in the regulatory floodway or in a designated V-Zone. Further, I certify that all applicable Federal, State, and local laws have been complied with, and all Federal, State, and local permits required for the work have been obtained and submitted into the folder for this job".
      (7)   Apply to FEMA for Final LOMR-F. After the Borough Commissioner signs the Community Acknowledgement Form, the owner shall submit such signed form to FEMA.
      (8)   Submit to the Department the approved LOMR-F and either a signed elevation certificate or dry floodproofing certificate as required pursuant to Section BC G 105.3. No certificate of occupancy or other final signoff shall be issued by the Department unless and until the applicant submits to the Department the Final LOMR-F approved by FEMA and either a signed elevation certificate or dry floodproofing certificate, and until all documents and submissions required by this rule are microfilmed into the permanent records of the Department. Certificates of occupancy shall comply with Section BC G 106.5.

Add new Section 2.27.11 to read as follows:
2.27.11 Occupant evacuation operation
   Where elevators are provided for occupant evacuation, Occupant Evacuation Operation (OEO) shall be provided to function prior to Firefighter's Emergency Operation and shall conform to 2.27.11.1 through 2.27.11.6.
Note: See also Nonmandatory Appendix V for additional information.
   2.27.11.1 The requirements of 2.27.3.1 are modified as follows.
      2.27.11.1.1 The two-position switch in the lobby (2.27.3.1.1) and two-position switch in the fire command center (2.27.3.1.2) shall be labeled "BANK FIRE RECALL" and indicate the elevator bank that they control.
      2.27.11.1.2 An additional two-position key operated individual "CAR FIRE RECALL" switch per elevator, that will not change position without a deliberate action by the user, shall be located in the lobby at the designated level adjacent to the elevator it controls. Each switch shall be labeled "CAR FIRE RECALL" (with the car identification, as specified in 2.29.1, inserted), and its positions marked "NORMAL" and "FIREMEN SERVICE" (in that order) in letters a minimum of 5 mm (0.25 in.) high. Text shall be black on a yellow background. Each switch shall control the associated elevator in conformance with 2.27.3.1.6, but shall not control the other elevators controlled by the "BANK FIRE RECALL" switch (see 2.27.11.1.1).
      2.27.11.1.3 Each individual "CAR FIRE RECALL" switch shall terminate Occupant Evacuation Operation for the elevator it controls when placed in the "FIREMEN SERVICE" position. Each "BANK FIRE RECALL" switch shall terminate Occupant Evacuation Operation for the elevators it controls when placed in the "FIREMEN SERVICE" position.
      2.27.11.1.4 Each individual "CAR FIRE RECALL" switch shall be provided with an illuminated visual signal to indicate when Phase I Emergency Recall Operation is in effect for that car (see 2.27.3.1.5).
      2.27.11.1.5 To remove an individual elevator from Phase I Emergency Recall Operation, the individual "CAR FIRE RECALL" switch shall be rotated to the "NORMAL" position, provided that
      (a)   the "BANK FIRE RECALL SWITCH" and the additional two-position "BANK FIRE RECALL" switch, where provided, are in the "NORMAL" position; and
      (b)   no fire alarm initiating device is activated (see 2.27.3.2).

When this means is actuated, the fire alarm system shall provide a signal to the elevator system indicating that all floors are to be evacuated. The means to initiate total building evacuation shall be keyed as New York City standard #2642 and FDNY standard key.
   2.27.11.6 When any of the signals provided in 2.27.11.5 actuate, the elevators shall conform to 2.27.11.6.1 through 2.27.11.6.10 in order to move occupants from the floors affected by the fire to the elevator designated level.
      2.27.11.6.1 The variable message signs required by 2.27.11.2 shall indicate one of the following messages:
      (a)   On all floors being evacuated, they shall indicate that the elevators are available for evacuation and the estimated time duration in minutes for the next elevator to arrive.
      Text shall read: "Elevators and stairs available for evacuation. Next car in about "X" minutes."
      (b)   On all floors not being evacuated, they shall indicate that elevator service is not available.
      Text shall read: "Elevators temporarily dedicated to other floors"
      (c)   On the elevator designated level, they shall indicate that the cars are in evacuation mode and that passengers should not use elevators.
      Text shall read: "Elevators dedicated to evacuation. Do not enter elevator."
      (d)   If no elevators are available for Occupant Evacuation Operation (fire service, inspection, shut off, etc.), they shall indicate that elevator service is not available.
      On all floors being evacuated they shall also indicate that occupants should use the stairs.
      Text for floors being evacuated: "Elevators out of service. Use stairs to evacuate." Text for other floors: "Elevators out of service."
      2.27.11.6.2 Automatic visual signal or variable message sign, and voice notification in each car shall indicate that the car is being used to evacuate the building.

Add 24.5.2.1.3 Definitions. The following definitions are applicable to this section only.
Delivered Audio Quality (DAQ). A measure of audio quality over a transmission medium as defined in standards published in TIA/TSB-88C. The following table shows the DAQ descriptions as published in the document:
 
Delivered Audio Quality (DAQ) Faded Subjective Performance Description
1
Unusable, speech present but unreadable.
2
Understandable with considerable effort. Frequent repetition due to noise/distortion.
3
Speech understandable with slight effort. Occasional repetition required due to noise/distortion.
3.4
Speech understandable with repetition only rarely required. Some noise/distortion.
4
Speech easily understood. Occasional noise/distortion.
4.5
Speech easily understood. Infrequent noise/distortion.
5
Speech easily understood.
 
Dedicated Radio Console (DRC). A fixed location console that contains at least the following components:
      (1)   A handset or headset to broadcast and/or receive voice communications from/to ARCS.
      (2)   A visual display to identify all signals transmitted from the Firefighter handheld units and supervisory signals.
      (3)   Fire Department city wide standard key (#2642) to enable/disable radio transmission.
In-Building Auxiliary Radio Communication System (ARCS). Wireless two-way radio communication enhancement system installed in buildings to propagate Fire Department wireless frequencies for the use of the Fire Department in case of an emergency.
Repeater Channel System. A repeater system utilizing channels with paired receive and transmit frequencies. When a user within the building transmits on a repeater channel, the repeater system rebroadcasts the users' signal to the DRC and all users within the building on that channel. This transmission increases the distance from which users can directly talk with each other. A user at the DRC must enable repeater channel for users to communicate.
Simplex Channel System. A simplex system utilizing channels with the same frequencies for transmit and receive. Users communicate on simplex channels radio-to-radio without going through infrastructure. However, their radios need to be within a certain distance to be picked up by one another. A simplex system allows a user at the DRC to communicate with a user on a simplex channel anywhere in the building, even though the distance between the DRC and the user would typically be prohibitive. A simplex system only extends the transmission's reach for the DRC. It does not improve coverage between individual user radios.
