The audit identified a deficiency in the City’s process for reviewing building permit applications for structures in the FEMA- designated floodplain. Specifically, the auditor challenged the method used by City staff to determine whether an individual building project constitutes a "substantial improvement" subject to the City’s Flood Hazard Regulations. The audit report included a requirement that the City modify its permit review methodology to bring it into compliance with National Flood Insurance Program (NFIP) standards. In response to the audit findings, staff is proposing to clarify the process used to identify "substantial improvements" by adding a definition for the term "market value" to the Mtmicipal Code and by revising the methodology for determining the market value of existing structures and screening building permit applications for projects in the floodplain. In addition, staff recommends clarifying some additional floodplain management issues, such as health and safety exclusions from the Flood Hazard Regulations, crawl space construction standards, and the prohibition of new or expanded basements. These issues have been problematic for staff and building permit applicants due to ambiguous or missing language. Lastly, staff recommends that the exemption from the Flood Hazard Regulations for historic structures be extended to locally- designated historic structures. This report describes the public outreach meetings conducted by staff to inform and solicit input from those individuals and businesses potentially impacted by the proposed CMR:212:04 Page 1 of 13 regulation changes. Staff summarizes the comments and concerns made by participants during the meetings and provides responses for the key issues raised. The report also describes the potential consequences of non-compliance with the audit requirements. RECOMMENDATION Staff recommends that the. Council approve and adopt the attached ordinance (Attachment A) revising the City’s Flood Hazard Regulations (Palo Alto Municipal Code Chapter 16.52). The ordinance adds a definition for the term "market value", an exemption from the Regulations for locally-designated historic structures, and language to clarify problematic issues regarding health and safety exclusions, crawl space construction standards, and basement prohibition in the existing Regulations. Staff also recommends that Council approve a revised cost valuation methodology for determining whether building projects modifying existing structures constitute a "substantial improvement" that must comply with special floodplain construction standards. BACKGROUND Historically, the nation’s private insurance companies have been unwilling to offer flood insurance, due to the potentially catastrophic level of claims from even a single major flood. To remedy this situation, Congress established the National Flood Insurance Program (NFIP) in 1968 to provide flood insurance underwriting. NFIP-sponsored flood insurance is made available to residents and businesses in communities that elect to participate in the program. In return, in order to reduce its level of risk, the federal government imposes requirements on the participating community, including the codification of federal floodplain management regulations into local ordinances. Council first incorporated the federal requirements into the Palo Alto Municipal Code (PAMC) in 1979, by adopting PAMC Chapter 16.52, "Flood Hazard Regulations." City staff is responsible for enforcing the special building requirements contained in the Flood Hazard Regulations. These requirements apply to new construction and "substantial improvement" o.f existing structures within a Special Flood Hazard Area (SFHA), the area subject to flooding in the one percent (100-year) flood (see map - Attachment B). A "substantial improvement" is defined as "any repair, reconstruction, or~ improvement of a structure, the cost of which equals or exceeds fifty percent of the market value of the existing structure." The primary special building requirements mandate that the lowest floor of a regulated structure nmst be constructed at or above the Base Flood Elevation determined by the Federal Emergency Management Agency (FEMA). Other requirements include installation of adequate openings beneath the floor to allow for passage of floodwaters, placement of building utilities (e.g. water heater, furnace, etc.) above the flood level, use of flood-resistant building materials, and the certification of lowest floor elevations by a registered engineer or surveyor. It is important to understand the intent and context of the federal floodplain management regulations, particularly with respect to their applicability to existing structures. The CMR:212:04 Page 2 of 13 concept of retrofitting existing buildings to protect them from flooding when they are ~substantially improved" is consistent with FEMA’s mission as administrator of the NFIP. Through the NFIP, FEMA makes flood insurance available to residents and businesses nationwide. As an insurance provider, FEMA is motivated to minimize the number of at-risk properties, in order to reduce the potential damage claims by policy holders in the event of a major flood. Successful reduction of damage claims, in turn, allows the NFIP to lower the premiums paid by flood insurance policy holders. A recent article in the Palo Alto Daily Neu~s describes how the number of damage claims directly influences the cost of flood insurance (Attachment C). According to FEMA, the fifty percent threshold used to define ~substantial improvement" was chosen "as a compromise between the extremes of 1) prohibiting all investment in structures in flood hazard areas which do not meet minimum FEMA floodplain management requirements, and 2) allowing structures to be improved in any fashion without regard to the hazard present." Likewise, the "substantial improvement" regulation is consistent with the City!s goal to protect public health and safety. As evidenced by the widespread property damage caused by the overtopping of San Francisquito Creek in 1998, flood damage is a very real possibility for Palo Alto residents and businesses. Enforcement of the Flood Hazard Regulations, including the requirement to raise the floors of "substantially improved" buildings, will help to mitigate future flood damage. The ultimate goal of removing the burden of special building requirements and mandatory flood insurance currently faced by owners of property in the SFHA can only be achieved through elimination of the floodplain. This, however, is a long-term solution that will require expensive flood control modifications to San Francisquito Creek and the bayfront levees. Steady progress is being made towards this goal. The San Francisquito Creek Joint Powers Authority is working with Palo Alto, its other member agencies, and the US Army Corps of Engineers to identify a flood control solution for San Francisquito Creek. There is $100K in the FY 03-04 Corps budget to start a reconnaisance study of flood control options. In addition, the Santa Clara Valley Water District has successfully lobbied Congress to authorize $100K in the FY 03-04 Corps budget to reassess the bayfront levees and the need for improvements..Improving San Francisquito Creek and the bayfront levees would eliminate the remaining flood hazards in Palo Alto. Staff is working cooperatively with other local agencies to make these improvements happen, but realistically these projects have a 10 to 20 year horizon. FEMA and the State Department of Water Resources (DWR) periodically conduct °~Community Assistance Visits" (CAVs) to audit the floodplain management practices of communities participating in the NFIP. In Spring 2000, DWR staff conducted a CAV with the City of Palo Alto. The DWR auditor concluded that the City is in general compliance with the NFIP requirements. However, the audit identified a deficiency in the City’s process for reviewing building permit applications for structures in the FEMA- designated floodplain, formally known as the Special Flood Hazard Area (SFHA). CMR:212:04 Page 3 of 13 PAMC Chapter 16.52 (Flood Hazard Regulations) contains special building requirements that apply to new construction and to "substantial improvement" of existing structures within an SFHA. The DWR auditor identified inadequacies in the City’s methodology for reviewing building permit applications for modifications to existing structures. Specifically, the auditor challenged the method used by City staff to determine whether an individual building project constitutes a "substantial improvement" subject to the special building requirements. The audit report included a requirement that the City modify its permit review methodology to bring it into compliance with NFIP standards. PAMC Chapter 16.52 currently defines a "substantial improvement" as "any repair, reconstruction, or improvement of a structure, the cost of which equals or exceeds fifty percent of the market value of the existing structure." In order to ascertain whether proposed improvements to an existing structure constitute a substantial improvement subject to the Flood Hazard Regulations, Public Works staff reviews, each project by comparing the cost of the impro’~ements with the market value of the existing structure. The cost of the improvements is derived from information provided by the applicant on the building permit application form. Determination of the market value of existing structures has been more problematic and is the subject of the audit findings. PAMC Chapter 16.52 does not contain a definition for the term "market value." Since the term has multiple meanings in general usage, building permit applicants are often confused over how to interpret it. With guidance from local FEMA officials, Public Works staff developed a procedure for determining the market value of structures using. the depreciated replacement cost approach. Using this approach, market value is calculated by multiplying the replacement cost per square foot by the existing building square footage and then multiplying the product by a depreciation factor that is dependent upon the age and condition of the building. Public Works staff worked with the City Attorney’s Office to draft a definition for the term "market value" based on this concept. The definition was reviewed and approved by FEMA and DWR staff and has been incorporated into the State of California model floodplain ordinance and adopted by local agencies such as San Mateo, Lafayette, Mill Valley, Brentwood, and Contra Costa County. However, this definition of."market value" has not yet been incorporated into the City’s Flood Hazard Regulations. Due to the complexity and variability of multi- family residential, commercial, and industrial buildings, staff has relied primarily on professional appraisals based on the depreciated replacement cost approach to determine the market value of these structures. Staffhas used a standard rate of $120 per square foot for living area and $60 per square foot for garages as the depreciated replacement cost figures to determine the value of single-family residential structures. This one-size-fits-all approach for valuing single-family residential structures was the target of the DWR audit. CMR:212:04 Page 4 of 13 The DWR audit report states: "Our review found one serious problem with the City’s Floodplain Management Program. The serious problem identified is that the City inaccurately evaluates structures for substantial improvement and substantial damage. The City currently evaluates all structures as "luxury" quality at $120 per square foot as defined in the Means Square Foot Estimating Guide. However, many of the structures identified in the enclosed °~Floodplain Inspection List" are not ~°luxury" quality. Therefore, the cost per square foot for the actual structure evaluated is too high. To correct this serious problem, the City needs to modify its Substantial Improvement and Substantial Damage square foot building valuation so that it reflects the actual quality of the structure evaluated. It is also strongly recommended that the City adopt a definition for "Market Value." This definition is necessary because of the many older structures that are being improved within the City’s Special Flood Hazard Areas." Other Issues The revision of the Flood Hazard Regulations to add a "market value" definition provides a timely opportunity to clarify some additional floodplain management issues that have been problematic for staff and 15uilding permit applicants due to ambiguous or missing language. A detailed discussion of these additional regulation changes is included below. The existing Flood Hazard Regulations allow an exemption from the floodplain-related special building requirements for historic structures listed on the National Register of Historic Places or the California Register of Historical Resources. Staff would like to extend the exemption provision to locally-designated historic structures, as discussed below. DISCUSSION Recommended Follow-Up to DWR Audit As a follow-up to the DWR audit, staff reviewed options for conducting substantial improvement evaluations. The most accurate and rigorous method would be to base the cost of the proposed building improvements on a detailed construction cost estimate and to bage the market value of the existing structure on an appraisal by a professional real estate appraiser. Since the majority of remodeling projects clearly do not constitute a substantial improvement, however, staff sought to develop a simpler and less costly means to conduct an initial screening of projects to determine whether or not they trigger the substantial improvement threshold without requiring all applicants to incur the cost of a professional appraisal. Therefore, staff developed a methodology for conducting preliminary substantial improvement evaluations without an appraisal. Under this approach, the cost of the building improvements would be based upon the cost figure accepted by the Building Inspection Division on the building permit application. The market value of existing single-family residential structures would be determined by. staff CMR:212:04 Page 5 of 13 using a customized valuation methodology. The proposed methodology takes into account the unique characteristics (age, size, construction quality, amenities, etc.) of each individual structure while maintaining a streamlined review procedure that will allow for timely and accurate "substantial improvement" evaluations. The proposed evaluation .procedure is based on cost estimating data contained in Means Square Foot Costs, a nationally-recognized cost estimating reference guide that is updated annually and adjusted for local construction costs. Staff has input cost data from the estimating guide into a customized software application that will allow custom valuations of residential structures based upon the following factors: ¯Age of the structure []Square footage of the structure []Quality of construction (average vs. custom) []Exterior finish []Type of roofing materials ¯Number of bathrooms []Building upgrades (fireplaces, air conditioning,premium kitchen, etc.) The software also applies an adjustment factor for depreciation of the structure based on its age. A summary of the range of costs generated by this valuation methodology is provided in the attached tables (Attachment D). The unit cost figures are generally lower than the standard $120 per square foot figure currently used by staff to establish the value of existing structures. An example "substantial improvement" evaluation using the proposed technique is depicted in the attached narrative (Attachment E). Staff proposes to use this cost estimating software as a screening tool for.reviewing building permit applications for modifications to existing structures in the SFHA. In most cases, this tool will allow staff to accurately and efficiently determine which building projects constitute substantial improvements subject to the Flood Hazard Regulations. Applicants will be given the option to provide a detailed construction cost estimate and a property appraisal prepared by a certified professional if they wish to challenge the screening-level substantial improvement evaluation conducted by staff. Professional appraisals will be accepted provided that they are prepared based upon the depreciated replacement cost approach. The proposed cost valuation methodology was reviewed and approved by FEMA staff. The lower building costs generated by the new valuation methodology will tend to identify more projects as potential "substantial improvements," subject to the special floodplain construction standards, but this trend may be offset by more use of professional appraisals by permit applicants to establish higher building values. CMR:212:04 Page 6 of 13 During the summer of 2003, staff convened a peer review panel consisting of members of the local development community (developers, design professionals and appraisers) to review the proposed cost valuation methodology. A list of members of the peer review panel is attached (Attachment F). The peer review panel was supportive of staff’s approach. The panel noted that the construction costs listed in the Means Square Foot Costs are lower than actual local costs, but acknowledged that they are consistent with costs typically submitted by applicants on building permit applications for new construction. Panel members observed that the initial substantial improvement screening will produce an accurate assessment as long as the unit costs for new construction and existing improvements are relatively consistent. The panel also felt that it was important to include the option enabling an applicant to obtain a professional cost appraisal if they do not agree with staff’s cost estimate. In order to comply with the DWR audit of the City’s floodplain management practices, staff recommends that Council approve the attached ordinance incorporatin~ the "market value" definition into the Flood Hazard Regulations and approve staff’.s proposed cost valuation methodology for determining whether building projects modifying existing structures constitute a "substantial improvement." Although codification of the "market value" definition is not strictly mandatory, the proposed definition is consistent with written guidance from FEMA and staff’s interpretation of the term. Staff strongly recommends that the definition be added to the Municipal Code in order to clarify the issue and to avoid disputes with applicants over the meaning of the term. This will promote consistency and efficiency in processing applications. Additional Floodplain Management Issues In addition to adding the ~market value" definition, staff recommends amending the Code in order to clarify some additional floodplain management issues that have been problematic for staff and building permit applicants due to ambiguous language or areas where the ordinance is silent. The issues, including health and safety exclusions from the Flood Hazard Regulations, crawl space construction standards, and the prohibition of new or expanded basements in the SFHA, are discussed below. Section 16.52.040(35) of the Flood Hazard Regulations allows the exclusion of certain items of work when determining the cost of a building improvement project. By reducing the calculated cost of a project, these exclusions effectively allow more construction to occur before the "substantial improvement" criteria is triggered. One such exclusion is allowed for "any project for improvement of a structure to comply with existing state or local health, sanitary, or safety code specifications which are solely necessary to assure safe living conditions." The vague nature of the language in this code section has created confusion for both staff and building permit applicants. Citing this code section, applicants have asked staff to exclude such items of work as fire sprinklers and seismic upgrades from the cost of their projects in an attempt to keep the total project cost below the "substantial improvement" threshold. FEMA officials have advised staff CMR:212:04 Page 7 of 13 in writing that it may only exclude 1) those costs for work to correct pre-existing code violations that make the structure uninhabitable, and 2) work necessary to comply with the Americans with Disabilities Act (ADA) (see attached correspondence - Attachment G). Based on the guidance from FEMA, Public Works staff and the City Attorney’s Office have drafted alternative ordinance language that more clearly describes the intent behind the exclusion (see Attachment A). Section 16.52.040(5) of the Flood Hazard Regulations defines a basement as an area of a building having its .floor subgrade (below ground level) on all four sides. Basements are prohibited for new construction and "substantial improvements" to existing structures that are within the SFHA. Written FEMA guidance has indicated that subfloor crawl spaces that are below grade on all four sides are considered basements and are therefore prohibited. A prohibition of subgrade crawl space areas, however, is not explicitly made in the existing Flood Hazard Regulations. The lack of specific language prohibiting subgrade crawl spaces ~reates confusion for building permit applicants and makes it difficult for staff to enforce the prohibition. Staff proposes to modify Section 16.52.040(21). to explicitly prohibit subfloor crawl spaces that are subgrade (below ground level) on all four sides for new construction. As a result of local construction practices, subgrade crawl spaces are a common feature for residential structures in Palo Alto. Prohibiting subgrade crawl spaces on a new house is relatively straightforward since the building is constructed with new materials from the foundation up. Eliminating subgrade crawl spaces from existing houses that are being substantially improved, however, is much more problematic. The problem arises due to an inadvertent conflict with a Uniform Building Code rule that requires a minimum distance of 18 inches between the ground and the lowest structural member in the crawl space area (e.g. the floor joists) in order to provide adequate subfloor access. There are two typical scenarios for "substantial improvement" projects. In the first scenari.o, the lowest floor of the structure is below the base flood elevation for the parcel. In this case, the lowest floor of the entire house must be raised in order to comply with the Flood Hazard Regulations. Since the floor is required to be raised anyway, the applicant is required to fill in any subgrade crawl space area and then elevate the floor to a level that a) is at or above the base flood elevation, or b) provides the minimum 18 inches clearance above the ground, whichever is higher. The second scenario is the problematic one. In this scenario, the lowest floor is already above the base flood elevation so it does not need to be raised, but typically the house is built above a subgrade crawl space and most often the ground clearance is already at or near the minimum 18 inches. In this situation, filling in the subgrade crawl space violates the building code clearance requirement, but leaving the subgrade crawl space violates the Flood Hazard Regulations. In such cases, staff has elected to allow the subgrade crawl space to remain because it is considered onerous to require a permittee to incur the sizable cost to elevate the entire house simply in order to eliminate the minimal risk of damage that may occur if water accumulates in the crawl space during a flood event. Instead, staff has directed permittees to fill the CMR:212:04 Page 8 of 13 subgrade crawl space area to the extent feasible without violating the minimum clearance requirement. FEMA has recently issued written guidance that allows limited subgrade crawl spaces to remain if the following conditions are imposed on the project: "The crawl space grade must not be more than two feet below the lowest adjacent grade outside the foundation. []The height of the crawl space, measured from the interior grade of the crawl space to the top of the foundation wall, must not exceed four feet. []There must be an adequate drainage system that removes floodwaters from the interior area of the crawl space. The enclosed area must be able to be drained within a reasonable time after the flood event. [] The velocity of the floodwaters at the site should not exceed five feet per second. []Communities that choose to allow subgrade crawl spaces must amend their flood hazard regulations to reflect the other conditions listed above. Staff proposes modifying Section 16.52.130 of the Flood Hazard Regulations to allow subgrade crawl spaces to remain beneath substantially improved buildings, subject to the conditions dictated by FEMA. According to the existing Flood Hazard Regulations, the requirement that the lowest floor of a structure be constructed at or above the base flood elevation only applies to new construction or "substantial improvement" of an existing structure located in the SFHA. This effectively prohibits the construction of most basements in the SFHA. There is a loophole, however, that allows the construction of a new basement or the expansion of an existing basement in an existing structure, if the construction does not constitute a "substantial improvement." Staff believes that the health and safety risks caused by basements constructed beneath residential buildings located .in a floodplain should be sufficient cause for a policy of complete prohibition. The impacts to basements during a flood were made evident during the February 1998 San Francisquito Creek flood, when the Fire Department assisted with pumping out several hundred flooded basements and subgrade crawl spaces throughout the City. Therefore, staff has proposed modifications to Section 16.52.130 of the Flood Hazard Regulations that close the existing loophole and prohibit ~ new or expanded basements in the SFHA in order to protect public health and safety. Expanded Exemption for Historic Structures The existing Flood Hazard Regulations allow an exemption from the floodplain-related special building requirements for historic structures listed on the National Register of Historic Places or the California Register of Historical Resources. Specifically, the definition of a "substantial improvement" excludes alterations to a designated historic structure as long as the proposed alterations will not result in the termination of the structure’s continued designation as an historic structure. FEMA regulations also allow for the exclusion of locally-designated historic properties in communities with certified CMR:212:04 Page 9 of 13 historic preservation programs. Palo Alto’s historic preservation program is certified by the State of California in the City’s Certified Local Government Agreement, and the exemption of locally-designated historic properties from the Flood Hazard Regulations was included in the Historic Preservation Ordinance adopted by Council in 1999. The exemption was eliminated, however, when the Historic Preservation Ordinance was invalidated by voter referendum in 2000. Staff would like to reinstate the exemption provision for locally-designated historic structures in order to provide an incentive for voluntary historic preservation. In particular, the regulations would be modified to exempt "any structure that is listed individually in the current edition of the Palo Alto Master List of Structures on the Historic Inventory in Category 1 "Exceptional Building" or Category 2 "Major Building" or any structure that has been certified by the Keeper of the National Register as contributing to the historical significance of a registered historic district". It is expected that the potential exclusion from the Flood Hazard Regulations may induce some owners of properties listed as Category 3 or 4 on the Palo Alto Historic Inventory to seek the Category 1 or 2 designation if they qualify. The revised historic designation would allow property owners to implement extensive remodeling plans without having to elevate their structures, as long as the-historic nature of the structure is not compromised. In turn, the voluntary addition of properties to the Category 1 or 2 inventory would increase the City’s ability to ensure the continued preservation of these historic properties and thus benefit the City’s overall efforts ~to promote historic preservation: Public Outreach In addition to convening, the peer review panel for purposes, of commentary on the "substantial improvement" cost methodology discussed above, staff has conducted outreach to those impacted by the recommended ordinance changes. Staff arranged a series of public lneetings with residential property owners, commercial property owners, the Chamber of Commerce, and local realtors to provide information and receive feedback. The meeting for residential property owners was publicized through direct mailing to neighborhood association representatives and paid advertising in local newspapers. Individual meeting invitations were mailed to all owners of commercial property in the floodplain. The attached table lists the target audiences and meeting dates of staff’s outreach efforts (Attachment H). The residential property owner representatives, local realtors, and the Chamber of Commerce Government Action Committee were generally supportive of staff’s proposed ordinance changes. There were a couple of notable concerns expressed by members of the public during the meetings. Many meeting attendees commented that the construction costs used to determine market value at the building permit screening phase are too low. The participants generally understood staff’s rationale supporting the methodology for initial screening of building permit applications (i.e. streamlined review procedure; customized approach based on the building’s size, age, construction quality, and amenities; the use of similar cost ranges for the cost of building improvements and CMR:212:04 Page 10 of 13 for building replacement costs, etc.), but found the process somewhat confusing. If Council approves the proposed cost valuation .methodology, staff will prepare written guidance materials to clarify the process for permit applicants. Some residential property owners questioned why basements are allowed for commercial properties in the floodplain (as long as they are flood-proofed), but are prohibited for residential structures. One resident noted that FEMA regulations allow municipalities to permit residential basements under certain conditions and advocated that Palo Alto take advantage of this opportunity to allow residential basements. Staff has researched the FEMA regulations and has concluded that it would be difficult to comply with all of the conditions required to allow the City to permit residential basements (see summary of the requirements in Attachment I). In any case, staff continues to believe that the health and safety risks caused by basements constructed beneath residential buildings located in a floodplain are sufficient cause for a policy of prohibition. The commercial property owners represented at the February 4 meeting expressed strong opposition to the proposed "market value" definition. They argued that staff is exceeding the minimum requirements of the National Flood Insurance Program by proposing a "market value" definition based on depreciated replacement cost. Furthermore, they contended that staff’s proposed definition will negatively impact commercial development in Palo Alto. They noted that the existing Flood Hazard Regulations provide that undefined terms "shall be interpreted so as to give them the meaning they have in commonusage and to give this chapter its most reasonable application." Under this approach, they believe that term "market value" should be interpreted as "the sales price mutually acceptable to a buyer and a seller" or "the value of a property based upon its income-producing potential", common meanings of this term in the commercial real estate business. Staff is basing its recommendation on the specific verbal and written guidance on this issue provided by FEMA and California DWR staff. Several years ago, at the urging of some commercial property owners, staff wrote to FEMA seeking approval to use income-based appraisals to establish the market value of existing commercial buildings. FEMA responded by rejecting this approach and reinforcing the validity of the depreciated replacement cost methodology (see attached correspondence - Attachment J). RESOURCE IMPACT Council adoption of the attached modifications to Palo Alto Municipal Code Chapter 16.52 (Flood Hazard Regulations) will ease the workload on existing staff by clarifying ambiguities or omissions in the existing regulations. In an effort to determine the impact of the Flood Hazard Regulations on commercial development, staff reviewed building permit applications for commercial buildings in the floodplain during the period from 1998 through the present. Of the 177 permit applications received during this period, only six were found to be substantial improvements. Two of the projects were never built, one was floodproofed by elevating CMR:212:04 Page 11 of 13 low-lying doors and windows and strengthening the walls, and three were either elevated or already met the minimum floor height requirements. Failure to comply with the audit could result in the loss of the 15% flood insurance premium discount enjoyed by Palo Alto residents and businesses due to Palo Alto’s participation in the NFIP’s Commu.nity Rating System and its good standing in the NFIP. In a worst case scenario, Palo Alto could be suspended from the NFIP, which would make federally-backed lnortgages unavailable to borrowers on properties located in the floodplain. ¯POLICY IMPLICATIONS Council adoption of the attached modifications to Palo Alto Municipal Code Chapter 16.52 (Flood Hazard Regulations) will bring Palo Alto’s floodplain management program into full compliance with National Flood Insurance Program (NFIP) standards. Adoption of a "market value" definition and approval of the modified methodology for valuation of existing single-family residential structures will represent a change from the current valuation methodology and will comply with the requirements of the Spring 2000 audit by the California Department of Water Resources. ENVIRONMENTAL REVIEW Adoption of the attached ordinance is exempt from the provisions of the California Environmental Quality Act (CEQA) as a minor alteration in land use limitations in an area with an average slope of less than 20% which does not result in any changes in land use or density (CEQA Guidelines Section 15305).

ATTAC H ME NT C -.flood one properties INblAN NEWS A federal program that insures homeown- ers .against the risks of flood has paid multi- pie claims on tens of thousands of particu- larly flood-prone homes. The insurance pro- gram is sound, but improvements should be implemented to stop these so-called "repeti- tive loss" properties from continuing to drain the program’s resources. The National Flood Insurance Program insures 4.4 million homes around the coun- try. Some 48,000 of those insured proper- ties, a mere one percen~ of the totar, have been flooded at least twice in the last 10 years. Those claims .cost the program $200 mil- lion each year and account for 25-30 per- cent of the claims paid, according to a itate- ment from the National Association Of Home Builders. The Federal Emergency Management Agency, a division of the U.S. Department of Homeland Security, operates - the program. The builders group last week called On Congress to "address repetitive loss proper- ties in order to ensure .the long-term viabili- ty" of the National Flood Insurance Pro- gram. The group also wants Congress to "narrowly define severe ’repetitive loss’ properties to include only those that pose the most severe flood risks." This approach would.direct FEMA "to. address the most problematic properties .first, which would quickly lead to signifi- cant savings to the NFIP and ensm’e its long-term viability," Steve Feldmann, direc- tor of community affairs for the Fischer Group, a home builder in Kentucky, last week told a U.S. Senate subcommittee. There’s no question that Congress should take action. However, a too-narrow defini- tion.of repetitive loss properties would leave in place the cmTent injustice of 4.4 million policyholders each paying an exti’a $45.45 each year for those 48,000 sadly and unfortunately flood-prone homes. The high cost of repetitive loss properties to the national flood program is not a new problem. In fact, it’s a’problem that’s exist- ed for years. .Legislation first proposed nearly five years ago would have set aside $400 mil- lion-two years’ worth of repetitive-loss payouts to buy 6ut homeowners who suf- fered repetitive flood losses. Those who didn’t want to sell.or elevate their properties could have kept their federal flood insurance, but wouId have had to pay market-rate premiums, instead Of the iow subsidized rates. The "Two Floods and You’re Out" legislation wasn’t enacted, and maybe it wasn’t exactly the fight solution. Nonetheless, it’s high time Con.gress took action to fix the problerd of repetitive-loss properties, and that action should be aggres- sive and results-oriented, not merely sym- bolic. Congress also should take the real estate ifidustry’s advice and make the "flood insur- ance program permanent or at least reautho- rize it for several years at a time. The pro- gram is routinely reauthorized year after year, except when Congress is too busy to attend to it. In those years, the program lapses just .long enough to .create unnecessary stress and confusion for home buyers. Permanency would add stability and save people who buy a flood-plain house during a lapse peri- od some trouble and worry gbout their new- bought home.

As a follow- up, we would like FEMA to clarify the procedure for establishing the cost of improvements for remodeling projects. Specifically, we seek your guidance regarding the types of "health, sanitary, or safety code requirements", that can be excluded from the cost of a project when analyzing whether or not the project constitutes a "substantial improvement." The City’s floodplain management ordinance (Palo Alto Municipal Code Chapter 16.52) provides that the term "substantial improvement" does not include "any project for improvement of a structure to comply with existing state or local health, sanitary, or safety code specifications which are solely necessary to assure safe living conditions. " It is our understanding that the inclusion of this language .in the ordinance is intended to prevent the floodplain management regulations from inadvertently discouraging building owners from implementing health and safety improvements to their structures. Furthermore, it seems appropriate to us that this exclusion can be interpreted to apply to a closely-related group of similar types of improvements, such as those listed below: Modifications to facilitate building accessability (Americans with Disabilities Act (ADA)/Uniform Building Code) Seismic safety structural improvements (Uniform Building Code) Installation of fire sprinkler systems (Uniform Fire Code) Water quality protection features (City of Palo Alto Sewer Use Ordinance [Chapter 16.09]) Asbestos and lead abatement (Federal and Cal/OSHA) P.O. Box 10250 Palo Altm, CA 9.4303 Letter to John Eldridge November 20, 1996 Page 2 Hazardous materials storage (City of Palo Alto Hazardous Materials Storage Ordinance [Title 17]) We believe that each of these categories of improvements results in tangible and significant benefits to the health and safety of the members of our community and should be promoted on an equa! basis with floodplain management practices. Furthermore, it seems that to utilize the value of these mandated improvements to trigger the determination of a substantial improvement and its associated flood-related building requirements could be construed as placing the applicant in a form of regulatory "double jeopardy," which we would like to avoid. Therefore, unless we are advised otherwise by .FEMA, the City intends to exclude the cost of these categories of improvements from the cost of proposed building remodeling projects when analyzing whether or not the projects constitute a "substantial improvement." Furthermore, in order to encourage voluntary implementation of these health and safety improvements, we intend to exclude the costs of the improvements when they are voluntarily included in a project, as well as when they are required by code or City ordinance. Please provide a definitive written response to this request so that we may proceed with finalizing the revisions to our floodplain management ordinance.

Roberts Director of Public Works City of Palo Alto P O Box 10250 Palo Alto, CA 94303 Dear Mr. Roberts: Thank you for your .letter regarding clarification of the substantial improvement criteria. We apologize for the delayed reply, but our disaster committments have overcome the normal duties of the office. We hope you understand. The criteria to which you address are those of a "compliance" nature, whereby if they werenot completed, the structure would be ~red-tagged" by the community. Therefore, "optional" improvements are not qualifiers for exemption from the computation. The active terms are ~compliance with health, sanitary, or safety code". FEM_A has interpreted these criteria as those that are clearly "mandatory", in other words, had the community known of the nature of the issue before the substantial damage occurred, they would have red-tagged the structure. We have exempted ADA requirements from inclusion, but they only apply to public structures, (ie. Where public visitation occurs), as opposed to residential or other private structures. Those issues of water quality, seismic, asbestos/lead, hazardous materials, or sprinkler units fall to the question of ~would they have been red-tagged". Please also note there are specific NFIP requirements regarding hazardous materials storage that must be complied with in addition to city restrictions. It is not our intention to inadvertently discourage building owners from implementing health and safety improvements, but at the same time, we have an obligation to also encourage compliance with NFIP regulations as well, in the interest of avoiding future flood losses. While we agree that your identified improvements produce tangible and significant benefit to the community, we are obligated, as are you, to support the objectives and goals of the NFIP. This is hardly "double jeapardy" when two clear goals are obtained in attaining compliance with both NFIP and one or more of your defined objectives.

(c) A community may propose flood plain management measures which adopt standards for floodproofed residential basements below the base flood level in zones A1-30, AH, AO, and AE which are not subject to tidal flooding. Notwithstanding the requirements of paragraph (b) of this section the Administrator may approve the proposal provided that: (1) The .community has demonstrated that areas of special flood hazard in which basements will be permitted are subject to shallow and low velocity flooding and that there is adequate flood warning time to ensure that all residents are notified of impending floods. For the purposes of this paragraph flood characteristics must include: (i) Flood depths that are five feet or less for developable lots that are contiguous to land above the base flood level and three feet or less for other lots; (ii) Flood velocities that are five feet per second or less; and (iii) Flood warning times that are 12 hours or greater. Flood warning times of two hours or greater may be approved if the community demonstrates that it has a flood warning system and emergency plan in operation that is adequate to ensure safe evacuation of flood plain residents. (2) The community has adopted flood plain management measures that require that new construction and substantial improvements of residential structures with basements in zones A1- 30, AH, AO, and AE shall: (i) Be designed and built so that any basement area, together with attendant utilities and sanitary facilities below the floodproofed design level, is watertight with walls that are impermeable to the passage of water without human intervention. Basement walls shall be built with the capacity to resist hydrostatic and hydrodynamic loads and the effects of buoyancy resulting from flooding to the floodproofed design level, and shall be designed so that minimal damage will occur from floods that exceed that level. The floodproofed design level shall be an elevation one foot above the level of the base flood where the difference between the base flood and the 500-year flood is three feet or less and two feet above the level of, the base flood where the difference is greater than three feet. (ii) Have the top of the floor of any basement area no lower than five feet below the elevation of the base flood; (iii) Have the area surrounding the structure on all sides filled to or above the elevation of the base flood. Fill must be compacted with slopes protected by vegetative cover; Page 1 of 2 Attachment I (iv) Have a registered professional engineer or architect develop or review the building’s structural design, specifications, and plans, including consideration of the depth, velocity, and duration of flooding and type and permeability of soils at the building site, and certify that the basement design and methods of construction proposed are in accordance with accepted standards of practice for. meeting the provisions of this paragraph; (v) Be inspected by the building inspector or other authorized representative of the community to. verify that the structure is built according to its design and those provisions of this section which are verifiable.

Our goal is to develop a clearly defined set of procedures that are easily understood by applicants, City review staff and FEMA representatives. The most challenging aspect of the task to-date has been documenting a methodology for.establishing the "market value" of existing structures as part of determining w_hether or not a project constitutes a substantial improvement. As you know, "market value" is not defined in the City’s floodplain management ordinance nor in the model ordinance developed by the State Department of Water Resources (DWR). In the absence of a definition, some permit applicants have questioned the City’s interpretation of market value, as well as the intent behind FEMA’s use of the term in its regulations. The City will be updating its floodplain management ordinance in the next few months as requested by DWR staff during a recent Community Assistance Visit. We plan to take this opportunity to clarify the meaning of "market value" by defining the term in the revised ordinance. Prior tQ ’finalizing a "market value" definition for consideration by the City Council, staff reviewed the policy guidance provided in FEMA Publication 213 and discussed the issue with Ken Nauman of your staff. We also held meetings with local developers and property owners to solicit their input and comments. Ken attended one of the meetings to provide FEMA’s perspective.on the topic. During the meetings, several questions were raised regarding use of professional appraisals to establish market v)due. Before proceeding.to City Council with a recommendation, we need clarification from FEMA on this issue. P.O. Box 10250 Palo A~to, CA 94203 Letter to Federal Emergency Management Agency September 9, 1996 Page 2 Per FEMA Publicati6n 213, an acceptable estimate of market value can be obtained from an ."independent appraisal by a professional appraiser". One of the Standard appraisal methods used by professional appraisers is the "capitalization or income method," which establishes property value based upon the income that the property generates. Using this method, the value of a structure on that property is obtained by subtracting the land value from the total property value. Given the language of FEMA Publication 213 and the widespread use of the income method by the appraisal community, it seems appropriate to us that this method can be used as one way to determine market_value. Unless we are advised by FEMA that this market value methodology is not acceptable to FEMA, the City intends to permit an appraisal prepared in accordance with the "capitalization or income method" to be used to establish the market value of an existing structure. An example using this income-based methodology is included to assist in your review of this issue. Please provide a definitive written response to this request so that we may proceed with developing a definition of °°market value" for inclusion in our floodplain management ordinance. If you have any questions or need further information, please call Joe Teresi of my staff at (415) 329-2129. Sincerely, Glenn S. Roberts Director of Public Works JT:GSR/sm Attachment:Example of inc0me-based appraisal cc~Bernie Strojny Carol Jansen George Bagdon Joe Teresi ~Tlnls is a letter of opinion regarding the above-referenced property. You have asked me to estimate the ~.market value of the of the structure" at this location. Information you provided to me indicates that the property has been leased on the basis of $480,000 per year after it is improved at cost to the lessor. Vv~e have estimated the "a~ is" market value of the leased fee interest in the subject property assuming this information is correct. The market value of the structure is based on first estimating the value of the property in its =as is" condition and then deducting the value of the land and the improvements that are not part of the structure. Such improvements include the parking lot and landscaping. Based on the guideEnes of the Unifo~n Standards of Professional Appraisal Practice (USPAP) adopted by the Appraisal Foundation, this letter represents a "Emited" appraisal in =restricted" report format. (See attached Standards Rule 2-2 Comparison Chart) The purpose of the_report is to estimate the "as is~ residual leased fee value of the property after deducing land value .and non-structural improvements. I understand that you will use this let{er to meet City of Palo Alto requirements-relating to properties which are located in flood hazard zones. The definition of market value is shown at the end of this report. We have reviewed plans .for the subject property and have Page 2 investigated market information for sLmilar properties to the subject in dete’~-mining that a) $2.00 per square foot rent, b) $20.00 per square foot land value, and c) a nine percent capitalization rate are reasonable in the current market. These are used in value calculations on the following page. The scope o£ the assignment is very limited in that we rely on information provided by you, and while we have inspected the property, we have not fully investigated market and other factors as we would normally do in a full appraisal. I have conducted an Income Capitalization Approach assuming an annuai rent of $480,000 per year from an average or above-average credit ~ce_nant for three or more years and ~vith periodic inflation increases to the rent. I have not used the Cost and the Sales Comparison Approache~. The limitations discussed above, are departures from the Uniform Standards. The market value of the leased fe~ interest in the whole property in its =as is’" condition as of ~anuary 16, I996, the date of inspection and the effective date of this.appraisal, is estimated at $4,335,000. Deduc*dng the land value and the site improwemen~s (landscaping, "parking improvements, etc.) of $1,127,492 yields a =market value of the structure" in its =as is" condition of $3,207,508, rounded to $3~200,000. This repo~c may be relied upon only by you and by the City of Palo Alto insofar as the scope of the assignment outJAned above meets, their criteria. The calculations on the fol!owing page !ead to the conclusionas to the =as is" market value of the leased fee interest in the su-ucture, subject to the limiting conditions discussed as depart .ures from Un~orm Standards above and subiect to the general limiting conditions described at the. end of this report.

A current economic definition agreed upon by Federal financial institutions in ~the United States of America, as set forth in the Uniform Standards of Professiona! Appraisal Practice, 1990, page I-7, is as follows: The most probable price which a property should bring in a competitive and open market under all conditions requisite to a fair sale, the buyer and seller each acting prudently and knowledgeably, and assuming the price is not affected by undue stimulus. Implicit in this definition is the consummation of. a sale as of a specified date and the passing of title from seller to buyer under conditions whereby: I.Buyer and seller are typically motivated; Both parties are well informed or well advised, and acting in what they consider their best interests; A reasonable time is allowed for exposure in the open market; Payment is made in terms of cash in United Statesdollars or in terms of financial arrangements comparable thereto; and The price represents the normal consideration for the property sold unaffected by specia! or creative financing or sales concessions granted by anyone associated with the sale. Increments or diminutions in marketvalue attributable to special financing terms are measured against the all-cash standard, and any dollar amounts of variance from the cash standard are estimated and reported in analyzing comparable data. Leased Fee Estate. An ownership interest held by a landlord with the rights of use and occupancy conveyed by lease to others. The rights of the lessor (the leased fee owner) and the leased fee are specified by contract terms contained, within a ~lease.

Roberts Director of Public Works City of Palo Alto P.O. Box 10250 Palo Alto, CA 94303 Dear Mr.- Roberts: Thank you for your letter dated September 9, 1996, regarding an the determintation of "market value" using the "capitalization or income method" for substantially improved or damaged properties. The "independent appraisal by a professional appraiser" cited in the FEMA Publication 213 does not incorporate appraisals based upon capitaliZation or incom ’ . d. Property based insurance programs center on th~_G~nstruction value/of the building, in other words, the labor and materials to construct, rebuild,.or rep_a_ir the structure. The intent is ot~staDlish a basis th-~t------ will be objective in’it’s use for determining a likelihood of risk versus cost, ~s it pertains to flood insurance claims. Your selection of definitions for inclusion in your ordinance should include your staffs’ analysis of the FEMA 213 options cited in Question 21, page i0. As can be observed, all options center on the value of the st~-~cture, as oppgsed to the income it might be able to garner. Further, question 22 identifies the potential of erroneous "assessed values" that must be tempered by judgement and the ultimate objective of providing a reduction.in the risk potential of the structure. We appreciate your inquiry and the efforts the City has taken in support of the program. If you have any further questions, please contact me or the planner for your area, Mr. Ken Nauman, at (415) 923-7196. Sl~rely, (~ohn W. Eldridge Chief, Community Mitigation Programs Branch
