OVERVIEW The City of Clearwater, Florida, submitted a partial Repetitive Loss Plan application, in accordance with the 1990 special addendum, on December 14, 1990. During the year of 1991, the City has prepared this effective Repetitive Loss Plan. In addition, in order to move forward with the development of solutions to flooding problems, the City has completed a drainage study of Stevenson Creek, including design /permitting, (this basin z contains ±30% of the identified repetitive loss sites), started construction of the improvements of Stevenson Creek, and prepared and adopted a stormwater utility program to provide a funding source for the implementation of other solutions. II. PROBLEM IDENTIFICATION: A. RECENT FLOOD HISTORY ,t The City of Clearwater has had several floods since 1978 resulting in private property damage. According to the National Flood Insurance Program (NFIP), Detail of rk; Repetitive Loses by Community for Claims on or after January 1, 1978 computer printout, the City of Clearwater (Community Number - 125096) has nineteen (19) petitive loss properties. By re definition, a repetitive loss property is one for which two or more NFIP losses of at leas t $1,000 each have been paid since 1978. The repetitive loss properties are mainly concentrated in three (3) areas: Coastal Communities, and areas adjacent to the streams within the Stevenson Creek and Alligator Creek drainage basins. These three (3) areas have been designated by FEMA as being floodprone and have been assigned flood elevations. Two isolated properties (properties outside of designated floodprone areas) have also been identified as repetitive loss sites. These properties are located at 402 N. Railroad Avenue and 1460 Byram Drive. The City's repetitive loss areas and properties are shown on Exhibit 1. The owners names and addresses of the repetitive loss sites are shown on Exhibit 2. Y I .

Railroad Avenue Clearwater, FL 33515 -4143 4 raj L B. SOURCE OF PROBLEM 1. Coastal Communities - The properties with Bayview Drive South, Bay Esplanade, Coronado Drive, Eldorado Avenue, Heilwood, Gulf Boulevard, and Lantana Avenue addresses are in the Coastal flood areas. All of the flooding at these properties occurred during tropical storms and /or heavy rains associated with weather disturbances. Many of the structures were constructed prior to adoption of the current FEMA flood control standards. Storm outfalls (catch basins, inlets, I` etc.) below mean high tide, lower than desirable building elevations, and the topography of the areas all were contributing factors to the repetitive losses, caused generally by tidal flooding. • 2. Stevenson Creek -The properties with South Betty Lane, Barry Street and Pinebrook Road addresses are within the Stevenson Creek drainage basin. eather disturbances generated heavy rains which Tropical storms and other w overloaded that drainage basin. Repetitive losses at these addresses occurred because of several factors: development concentrated along the creek banks; j restricted drainage channels; undersized storm drainage systems and related appurtances; channel blockages during heavy rainfall events. 3 3. Alligator Creek: 2950 Glen Oak Avenue is within the Friendly Village of Kapok, a mobile home park located within the Alligator Creek drainage basin. The losses have occurred because the park is built in a low area in the basin characterized 1 by downstream constrictions. Environmental and economic considerations have l; hampered the ability to install the wide scope of drainage improvements needed to resolve the flooding problem. Past improvements, completed in 1983, have served to lessen the severity of the flooding. 4. Isolated Buildings - a. The structure at 402 North Railroad Avenue was constructed in a low area that does not have adequate drainage outfalls. Their exists an abandoned railroad track paralleling North Railroad Avenue. The railroad tracks were constructed at a higher elevation than the roadway and currently acts as a dike. Therefore, during heavy rains, the water collects at the property and causes flood damage. b. The structure at 1460 Byram Drive was constructed with the finished floor below the roadway elevation. Their is currently no mechanism in place to transport the stormwater runoff away from the structure. No other major deficiencies are known to exist in the storm drainage systems in this area �.� that would cause the flooding. ey i G r, ' 0 L] C. FLOOD DATA 1. Coastal Communities: FEMA has studied the Coastal Communities and has assigned base flood elevations and identified velocity zones. These are shown on Flood Insurance Rating Map Community Panel Numbers 125096.0003.D; Y % 125096.0007.D, and 125096.0014.D. 2. Stevenson Creek: The City of Clearwater contracted with an engineering consultant in 1988 to prepare a drainage study for major portions of the Stevenson Creek Drainage Basin. The intent of the study was to review, modify and refine the previous drainage study of Stevenson Creek prepared by Pinellas County in 1980 -1981. The drainage study provides design of channel and structural improvements to reduce flooding and damage within the watershed. 3. Alligator Creek: Pinellas County has contracted with an engineering firm to design of portions of the improvements proposed by HDR in the Pinellas County Storm drainage basin study dated 1981. The proposed improvements would lower computed flood levels along Channel "A" upstream of U.S. Highway 19. f Existing and proposed computed hydraulic grade lines are shown on plan /profile sheets prepared for Pinellas County by HDR in 1979. 4. Isolated buildings: a) A drainage study of-the area adjacent to North Railroad Avenue in 1991 was recently completed. The study called for a cross culvert located under the railroad tracks across the road from the repetitive loss site. b) There is no know drainage study encompassing the area adjacent to 1460 Byram Avenue. III. FLOOD HAZARD AREA INVENTORY A. DAMAGE -PRONE BUILDINGS 1. Coastal Communities: The Coastal Communities are comprised of Island Estates, Clearwater Beach and Sand Key Beach. According to the existing Land Use Comprehensive Plan, the Coastal Communities currently have 1,136 single family houses, 4,982 multi- family units. All of the buildings are either in velocity or base flood zones. 6 2. Stevenson Creek: Stevenson Creek is approximately 4.2 mites long and transects the western portions of the City. The creek has been studied and flood elevations assigned. By overlaying the designed FEMA flood zone limits on City aerials, it was estimated that 367 single family homes, 165 multi - family buildings, 171 commercial buildings and 48 City owned buildings are located within the Stevenson Creek floodprone areas. 3. Alligator Creek: Alligator Creek Channel "A" is approximately four (4) miles long and transects the eastern portion of the City. By overlaying the designated FEMA flood zone limits on City aerials and researching water meter records, it was estimated that 181 single family homes, 147 multi - family buildings, 12 commercial buildings are located within the Alligator Creek floodprone areas. 4. Isolated Buildings: 402 North railroad Avenue and 1460 Byram Drive are both identified as repetitive loss properties. According to the FEMA maps, both properties are located within Flood Zone X. By definition, Flood Zone X are areas determined to be outside the 500 -'Year Flood Plain. B. DEVELOPMENT TRENDS The future land use plan for the City is presented as Exhibit 3. The repetitive areas have been delineated on the Plan. 1. Coastal Communities: The Coastal Communities within the City are essentially built -out. There remains only small isolated privately owned vacant lots sprinkled throughout the communities. The City owns several beaches and a park that will remain public property. Therefore, new construction will be primarily limited to replacing or reconstructing existing buildings. redevelopment will be required to meet the City's Zoning Ordinances and Building Codes. 2. Stevenson Creek The flood zone areas adjacent to Stevenson Creek are essentially built -out. There remains only small, privately owned parcels of land adjacent to Stevenson Creek. The City of Clearwater owns a golf course adjacent to the creek. The City has no plans to sell the golf course for private development. Therefore, new construction will be primarily limited to replacing or reconstructing existing buildings, Redevelopment will be required to meet the City's Zoning Ordinances and Building Codes, 3. Alligator Creek - The floodprone areas adjacent to Alligator Creek are either built -out or protected by environmental regulations. Therefore, new construction will be primarily limited to replacing or reconstructing existing buildings. r r f 0 , o CITY OF CLEARWATER FUTURE LAND USE PLAN j crrY COMMSION, 1921 RITA U.

Isolated Properties - These properties are built -out. Substantial improvements to these buildings will require that the City's Zoning Ordinances and Building Codes are met. C. DEVELOPMENT CONSTRAINTS 1. Ownership: The majority of the undeveloped areas located within the repetitive loss areas are owned by the City. The City has no plans to sell these properties which primarily consist of beaches and a golf course. 2. City Regulations: The City has adopted a flood plain ordinance that meets the minimum NFIP rules. In "A" and "V" zones, new buildings must be elevated above the base flood elevation. In the "V" zones, all new buildings must be elevated on pilings or peers so that waves do not batter the permanent building walls ( "break away" walls are permitted). The effectiveness of these standards have been proven by the void of repetitive loss properties of the Sand Key area of Clearwater constructed after the adoption of the flood plain ordinance. 3. City Policy: The City has a written policy regarding substantial improvement interpretation which is distributed to all new property owners located within the flood zone prone areas. The policy basically states that properties undergoing substantial improvements will be required to meet the City's Flood Plain Ordinance. The City policy memo is presented as Attachment 1. 4. Department of Natural Resources (DNR) - The DNR has set a Coastal Control Construction Line (CCCL) in the Coastal Communities. The intent of the CCCL is to restrict construction that could adversely impact beach and dune systems and marine life. Construction within the Coastal Control limits requires a permit from the DNR Division of Beaches & Shores. The CCCL currently is located on the Gulf of Mexico side of Gulf Boulevard. 5. Department of Environmental Regulation (DER) /United States Army Corps of Engineers (USCOE) - The DER and USACOE both have regulations restricting the development of environmentally sensitive areas. These regulations have become more stringent in recent years and the patterns appears to remain constant for the future. 6. Southwest Florida Water Management District ( SWFWMD) - The SWFWMD regulates stormwater management systems including the construction within 100 year flood plains. SWFWMD does not allow for development to have a net encroachment within a 100 year flood plain unless it is shown that no adverse impacts will occur. D. CRITICAL FACILITIES 1. The City of Clearwater has a fire station and a police substation located on Clearwater Beach. No other critical buildings including City Hall, hospitals, nursing homes are located within the repetitive loss areas. 2. Clearwater Memorial Causeway and the Sand Key bridge are also considered as critical facilities as they are on the designated evaluation routes for the Coastal Communities. E. COMMUNITY NEEDS, GOALS AND PLANS In 1959, the City of Clearwater adopted a Comprehensive Plan that identifies needs, goals, objectives and policies regarding elements such as Drainage and Coastal Zone Management. These were coordinated with other elements of the Comprehensive Plan to ensure the elimination of potential conflicts. The Comprehensive Plan was also certified by the Department of Community Affairs for its consistency with Plans presented by other municipalities. Goals and objectives of the Drainage and Coastal Zone Management elements of the Plan fit in well with those of the NFIP. Some of these goals and objectives are outlined below. 1. Drainage - Objective 16.2 - The City of Clearwater shall have a stormwater management plan which will identify and prioritize implementation of the most cost -' effective programs for stormwater management, including stormwater quantity and quality and addressing those projects included in the Pinellas County plan which are confirmed and found appropriate by this study, which is to begin by 1990 and to begin implementation by 1992. Objective 16.3 - Lower highwater profiles during storm events, as necessary, to reduce house flooding occurrences and to lessen the resulting adverse effects on public health, the natural environment, public and private property and inconvenience; maintenance and improvements of existing drainage facilities shall continue during the time of the stormwater management plan preparation. 10 • Objective 16.4 - Identify and begin implementation of the most cost effective and efficient program to reduce the occurrence of house flooding as prioritized and scheduled in the stormwater management plan by 1993. • Objective 16.7 - Provide sound fiscal management of the stormwater drainage systems to include management, maintenance, operation, and construction in accordance with the stormwater management plan and concurrent with its implementation, by 1992. 2. Coastal Zone Management - • Objective 21.1 - Clearwater shall administer land development regulations to protect public and private property and human life from the effects of hurricane winds and flooding. • Objective 21.3 - By 1994, the City and mobile home park owners shall develop a plan for removal of mobile homes to areas outside the coastal zone. 1) In addition, the Comprehensive Plan identified a need to establish a dedicated funding source to provide revenue for flood control, maintenance, retrofitting and treatment of stormwater. The recommended mechanism was the implementation of a Stormwater Utility Fee that would apply to all residential and business properties within the City limits. t IV. REVIEW OF POSSIBLE A(717IVITIES f A. WATERSHED MANAGEMENT MASTER PLAN Prepare a Watershed Management Master Plan that addresses, among other things, floodprone areas within the City limits and recommends alternatives to lessen or eliminate flooding during certain rainfall events. {�jx The following items are all possible activities that can be used to help minimize flood damage. Some items have already been implemented by the City of Clearwater and are shown in order to develop a more complete list of options and alterations. 11 B. INTER- AGENCY CONTACTS The following agencies should be contacted to determine if they have any information, ideas, studies or planned construction in the repetitive loss areas which could affect or be coordinated with the communities plan. 1. United States Corps of Engineers 2. Federal Emergency Management Agency 3. U.S. Department of Agriculture, Soil Conservation Service 4. Department of Natural Resources 5. Florida Department of Transportation 6. Southwest Florida Water Management District 7. Pinellas County Public Works Department i, C. FLOOD CONTROL 1. Stevenson Creek: The City of Clearwater has recently completed a drainage study for the Stevenson Creek Drainage Basin. The study identifies several construction projects which will substantially reduce the flooding of the repetitive loss area. The construction projects include upgrading of several bridges and culverts and the improvements of the creek channel. The Phase 1 improvements extend from Betty lane to Pierce Street and are projected for completion in 1992. Pinellas County currently has programmed the replacement of Betty Lane Bridge (Sta. 39 +96) in the near future. 2. Alligator Creek: Based upon the findings in the current drainage study, upgrade the capacity of the creek by improving the drainage structures and channel. 3. North Railroad Avenue: Cross culverts under the existing railroad tracks. The culverts will provide a conveyance system for the local drainage away from the homes. These culverts will substantially reduce the localized flooding in this area. D. PUBLIC AWARENESS 1. The property owners within the repetitive loss areas shall be informed that they own property in designated floodprone areas. This notification shall include the following: a) Information regarding the need for flood insurance and a contact person at the City to assist them in obtaining flood insurance. b) General information regarding flood proofing of homes. 12 ■ r" i e) The current City policy regarding substantial improvements within floodprone areas. d) Information regarding construction options when remodelling or additions to homes (i.e., constructing the addition at' a higher elevation. This would allow for the furniture from the existing living area to be moved to a dry area in case of flooding). 2. A public meeting shall be held to answer questions regarding the above mentioned notification. E. PRESENTATION TO THE BOARD OF ADJUSTMENT AND APPEAL The Board shall be informed of the construction options and latest floodproofing techniques for buildings in the floodprone areas. This information could be utilized by the Board to add conditions to variance requested for construction below established flood elevations in floodprone areas. F. CREEK MAINTENANCE PLAN The available conveyance capacity of the creeks transecting the repetitive loss areas must be fully utilized by eliminating the clogging of the creeks with silt, vegetation, and debris. Crews should be assigned to maintain the creeks. However, a maintenance plan should be prepared, first. The maintenance plan shall: 1. Be consistent with regional, state and local regulations. 2. Determine the manpower and equipment necessary to perform the maintenance activities. 3. Address the frequency of the maintenance activities. 4. Estimate the funding needed to implement the plan. G. ACQUISITION OF FLOOD - DAMAGED BUILDINGS A significant number of homes and businesses located in the Coastal Communities could be destroyed or substantially damaged following a hurricane or other extreme storm event. Where appropriate properties could be identified which would be obtained for parks. Funds should be in place to acquire such properties immediately after the substantial flooding. 13 I Cri H. RETROFITTING OF FLOOD - DAMAGED BUILDINGS As previously discussed, there currently exist several innovative ways to retrofit a structure such that all or part of the structure is protected from flooding. The City could develop a fund for low interest loans to property owners who wish to retrofit their structures within floodprone areas. To better market the idea, a "pilot project" home(s) could be retrofitted using City funds. Notification to other property owners describing the retrofit home would then be released through a publication in a newspaper having a general circulation in the area of operation. V. SELECTION OF APPROPRIATE ACTIVITIES It is the City of Clearwater's intent to reduce flooding in the designated repetitive loss areas. It is our sincere belief that implementation of the following activities will put the City one step closer to reaching its goal. A. Prepare a Watershed Management Master Plan to identify alternative solutions to current and potential flooding problems. Timetable: 1993 B. Agency Coordination - Contact the agencies listed in Section III.A. to determine if they have any information, ideas, studies or planned construction in the repetitive loss areas which would reduce the flooding. Timetable: Mid -1992 C. Construction - Construct the improvements to Stevenson Creek. The Phase 1 construction is described below: CONSTRUCTION PHASE 1 - BETTY LANE TO PIERCE STREET (STA. 39 +96 TO STA. 103 +00) - Construction Phase 1 begins upstream o� the Betty Lane bridge and extends to Pierce Street bridge. The channel between the Betty Lane bridge and the Palmetto Street bridge (Sta. 39 +96 to Sta. 54 +91) is influenced by the tidal action of Clearwater Harbor and ultimately the Gulf of Mexico. Due to this tidal action and reduction in velocity a large buildup of silt and debris has accumulated in the lower channel area and will be removed. Because flooding in this area does not appear to be severe, structural channel improvements are not necessary and are not recommended. In addition, the excavation of the channel should enhance the environmental characteristics and improve the hydraulic capacities. 14 1. The Palmetto Street bridge (Sta. 54 +91) will be replaced with four 10 ft. x 12 ft. box culverts. 2. The channel through the Clearwater Country Club (Sta. 54 +91 to Sta. 86 +86) will be cleaned of any foreign debris and maintained in a natural state. Since flooding in the golf course will not cause serious property damage, channelization is not recommended. A sediment trap is to be placed upstream of the Palmetto Street bridge. This trap will accumulate the silt and heavy pollutants carried by the stream and provide a convenient and accessible area for removal, thus providing beneficial environmental enhcowements with reduced maintenance efforts. 3. The constrictions in the channel at the Southern Coast Line Railroad bridge (Sta. 70 +36) will be removed and the banks under the bridge stabilized with 'a Type -3 natural channel. This action will reduce the headloss through the structure and reduce the flooding and damage to areas located upstream of the bridge. 4. The channel under and below the Drew Street bridge (Sta. 86 +86) will be channelized with a slope protection on the bottom and side slopes. This will protect the structure and channel from erosion due to the high velocities expected during the passage of storm events. 5. The channel (Section 1, Sta. 86 +86 to Sta. 96 +76) between Drew Street and Cleveland Street meanders through a mostly commercial office and multi - family } residential area which has built adjacent to the bank of Stevenson Creek. The City currently has very little rights -of -way in this section and since land value in this area is expected to be costly the channel size here must be kept small. These considerations necessitate the use of a Type 1 Channel. 6. The box culverts currently located at Cleveland Street (Sta. 96 +76) (two 7 ft. x 9 ft.) are not of capacity to convey the design storm and will be replaced with four 9 ft. x 11 ft. box culverts or three additional 8 ft. x 11 ft. box culvert. 7. A 20 foot -wide corfcrete- sheet -pile channel with a natural bottom exists between Cleveland Street and Pierce Street (Section II, Sta. 96 +96 to Sta. 103 +00). By hard lining the bottom of this channel no further improvements in this area should be necessary to convey the design storm. Timetable: by late -1992 L_T C1 15 D. Notification - Notify the property owners within the repetitive loss areas as identified in Section III.A.1. as described in Section IV.D.1. Timetable: by mid -1992 E. Public information service. Timetable: by late -1992 F. Board of Adjustment and Appeal - Hold a special meeting with the Board of Adjustment and Appeal members to discuss the latest floodproofing, construction options and retrofitting techniques. Timetable: by mid -1992 G. Creek Maintenance - Develop a creek maintenance plan as described in Section HLE. Timetable: By late -1992 H. Acquisition Plan - Develop a plan identifying the properties in the floodprone areas that the City would be interested in obtaining. Timetable: By late -1993 _ I. Acquisition Fund - Develop a fund to purchase flood damage properties which interest > the City. Timetable: By late -1993 I Retrofit - Retrofit a property within the floodprone areas. Timetable: 1993 K. Loan Plan - Develop a plan for low interest loan to be used to retrofit properties within floodprone areas. Timetable: 1993 16 ■ P L. Loan Fund - Develop a fund for low interest loans to qualified property owners within the floodprone areas, that meet the criteria outlined in the Loan Plan mentioned above, to retrofit their buildings. Timetable: 1993 VI PUBLIC INPLJ'T This draft plan will be presented to the City Commission during an open public meeting during 1992. The residents in the repetitive loss zones will be invited to attend the meeting. Additional meetings will be held as needed to approve the plan. (G: \57 \CITYCLW) M 17 CITY OF CLEARWATER BUILDING INSPECTIONS DMSION OF PLANNING AND DEVELOPMENT •a• POLICY MEMO EFFECTIVE MARCH 5, 1990 (SEVISEO SEPTEMBER 27,1991� Substantial Imnrovernent Interpretation SUBSTANTIAL IMPROVEMENT means: 1. With respect to any property located in an area of special flood hazard, any reconstruction, rehabilitation, addition, or other improvement, of a structure during a one (1) year period, the cost of which equals or exceeds Fifty (50) percent of the market value of the structure before the start of construction of the improvement. 2) For the purposes of this def nhion, construction is considered to have started when the First alteration of any wall, ceidu, floor, or other structural part of the building commences, whether or not that alteration affects the external dimensions of the structure. 3) The term includes structures which have incurred substantial damage, regardless of the actual repair work performed. 4) (a) The term does not, however, include any project for improvement of a structure to correct existing violations of health, sanitary, or safety code specifications which have been identified by the building official, and which are the rainirnum necessary to assure safe living conditions. (b) The.term does not include.any alterations of a structure listed on the National Register of Historic Places or the State- Inventory of Historic Places; provided that the alteration will not preclude the structures continued designation as a.historic structure on such National Register or State Inventory. SUBSTANTIAL DAMAGE means, damage of any Orion sustained by a structure where by the cost of restoring the structure to its before damaged condition would equal or exceed fifty (50) percent of the market value of the structure before the .damage occurred.. . _.._ MAR ZET'VALUE is; the value of the structure only (does not include land or site improvements), as determined by the Pinellas County Tax Appraiser if a MAI appraisal is not submitted. The following are definitions and interpretations of what is considered substantial improvement and what costs shall and shall not be included for pre -FIRM structures, those built before September 1972. 1) Additions are any increase in area or volume to a structure. When the cost for an addition exceeds 50% of the existing structure's market value, the project is considered substantially improved and subject to post -FIRM requirements. However, if the addition complies with the Flood Protection code and is independent, the existing structure can stay as is. 2) Reconstruction is the rebuilding of a structure which was damaged by any cause, i.e., fire, wind, flood, decay, termite, etc. If the cost of the reconstruction exceeds 50% of the existing structure's market value before the damage, then the reconstruction is considered substantially improved and subject to Post -FIRM requirements. The cost of all damages suffered must be included. Thus, a building which sustains damages exceeding 50% of its market value will 1` be subject to the substantial improvement rule, even if only part of the repair is done in an attempt to reduce the p cost below the 50% threshold. 3) Rehabilitation (remodeling) means improvements made to a structure, which do not result in an increase of area or volume. If the cost of rehabilitation exceeds 50010 of the structure's market value, then the rehabilitation is ! a considered substantially improved and subject to the POST -FIRM requirements. 4) Combination of the above cases shall be treated as one. Example, an addition and a remodeling of an adjacent room are simultaneously done. The cost of each is added together and treated as one toward the 50% rule, - Aft - 5 Repair work is that which is related to maintenancd type work and/or work done to meet mirsmum housing code and life safety requirements. This would include items such as replacing roofs, minor termite damage, bad electrical systems, deteriorated plumbing, a change out of heating or cooling systems, etc. These items, when not done as part of an addition, reconstruction, or rehabilitation will not count toward substantial improvement. They will eounj f part of substantial improvement or substantial damage. t) Freestanding structure is a building adjacent, but not connected to the main structure. There are two types of freestanding structures, accessory and all others. Detached structures which comply with 7B are considered accessory structures and do not necessarily have to be elevated. All other detached structures are subject to the post -FIRM construction requirements. 7) Adding a second story to a pre -FIRM structure. A) A second story addition is interpreted as a rehabilitation and addition since it normally involves removing the roof and/or an exterior wall. Therefore, the cost of constructing the second floor, including removal of the roof, is included in determining substantial improvement. B) Floodproofmg the portion below the Bit, rather than elevating the structure is not an allowable option to attain compliance. Detached garages, which are not connected to the existing structure and $) There are generally two types of garages: which are connected to are constructed in a way that they are considered an accessory structure; Attached garages, the existing.structure and for floodplain management purposes are treated as enclosures below the BFE. A) Attached garages. A garage attached to the main structure is exempt from the elevation requirement, if it is used solely for parking, building access, or storage.and.meets. the following: 1) No machinery or equipment such as furnaces, air conditioners, heat pumps, hot water heaters, washers, dryers, elevator lift, equipment, electrical junctions, circuit breaker boxes, and food refrigeration units, etc, are located below the BFE; and _ 2) All interior wall, floor and ceiling materials located below the BFE are unfinished and resistant to flood damage; and 3) The walls of any enclosed area below the BFE are constructed in a manner as to prevent flotation, collapse, and lateral movement and provide openings allowing flood waters in the area below the _. BFE. Even if an addition, rehabilitation, or reconstruction to an attached garage complies with the above mentioned conditions and is consistent in design and use with the existing garage (which also met these conditions), the cost of construction must still be counted toward the improvement for the entire structure. B) Detached Garages and Other Accessory Structures. A garage detached from an existing structure is exempt from the elevation requirement, if it constitutes a minimal investment and meets the following conditions: 1) Use of the garage is restricted to parking and limited storage. . 2) The garage is built using unfinished and flood resistant materials. 3) The garage is adequately anchored to prevent flotation, collapse, or lateral movement and provides openings allowing flood waters in the area below the BFE. 4) Mechanical, utility, or electrical equipment in the garage is elevated to or above the BFE or is floodproofed. n 5) The garage complies with floodway encroachment provisions. For determining substantial improvement, accessory structures are treated separately from the main structure. Therefore, the cost of an addition to a detached garage is compared only to the market value of that detached garage. If an addition, reconstruction, or rehabilitation to a detached garage meets the above mentioned conditions, then the addition can be considered in compliance with the flood codes. 9.191 b-immn9l bo1 Uv.. P 9) The following is how substantial improvement-ii determined A) The cost of improvements of properties located in special flood hazard areas shall be over a one year time period. The plan reviewer shall review files to locate any permits issued within one year of the current application and add those cost of improvements on to the current application when consideringbthbstantial improvement. B) Cost of construction shall include values of labor and material for the following: 1) Foundations; footers, slabs, piers, piles, etc. 2) Masonry; brick, block 3) Carpentry; rough and finish, doors, windows 4) Roofing; sheathing, framing members, roof membrane and covering; (tile, shingle, etc.) 5) Interior /exterior components of: walls and ceilings (wall board, insulation, framing members, etc.), soffits, floors (subfloor, framing insulation, etc.), other 6) Electrical (new wiring, service change /upgrade, etc.) 7) Mechanical (service chime, new systems, ducts, etc.) 8) Plumbing (new fixtures, new piping, water softeners, water heaters, etc.) 9) Cabinetry or cabinets 10) Wall & floor coverings, if we issue permit for rehabilitation. reconstruction or addition involving this type of work. 11) Trash & debris removal related to the addition, reconstruction or rehabilitation.

Architects, Engineers, surveyors) 5) Appliances; refrigerator, range, dishwasher, clothes washer /dryer which are not built-min (note: these items cannot be placed below BFE on Post -FIRM buildings) 6) Demolition, land clearing, and debris removal (if taking away and not replacing). All the costs for B and C shall be provided to the building official on all pre -FIRM projects and broken down into a form similar to the list above. 10) Construction costs for additions, reconstruction, and rehabilitation shall be provided by the applicant by one of the following methods: A) Estimate from Architect/Engineer and contractor of record. B) Cost bids from two contractors. C) Cost estimate from MAI appraiser and contractor of record. D) Copy of the contract between contractor and owner. E) ,( ost estimates from owner and at least one of the following: Architect of record, contractor, or MAI appraiser. The plan reviewer shall use the average of the estimates to determine the cost of construction. One of the bids should be from the contractor of record. The plan reviewer may also use the average cost per square foot of the most recent figures provided by the Southern Building Code Congress as a check of the cost estimates submitted.
