Office ( 142) Religious (77) City Limits Data Source: 2005 Aerial Photo Okaloosa County & City of Fort Walton Beach FIGURE 6 -1 EXISTING LAND USE DESIGNATIONS 6. 3 RESIDENTIAL UNITS The data was sorted by property type to determine how many properties were categorized as single family residential. This category also included properties with mobile homes, townhomes up to four), and duplexes. The count of single family residential properties in the City of Fort Walton Beach is 7,282 with 6,236 parcels containing structures (see Section 5 of this report). 6. 4 COMMERCIAL UNITS A residential property is not comparable to that of a commercial property in the case of the percentage of impervious area on the site. Commercial properties are typically much larger sites or include a much larger ratio of impervious to pervious area. Commercial property information was gathered from the same dataset provided by the Okaloosa County Property Appraiser. Since a majority of commercial sites consist of a maximum ratio of impervious to pervious area a mapping of the impervious areas was performed for commercial units to determine the site impervious area for each commercial parcel. Figure 6-2 depicts the sampled commercial properties throughout the City. For this report, 100% of the commercial sites were sampled and the impervious area for each parcel determined from the Okaloosa County Property Appraisers database. The range in size of properties sampled was from 0.01 of an acre to 39.48 acres with impervious areas ranging from 0.03 square feet to 969,292 square feet. Appendix B lists the commercial properties in the City by their parcel identification numbers and mapped impervious area and number of ERUs based on the sampling from the Okaloosa County Property Appraisers database. The number of ERUs for each property is generated by dividing the impervious area by the residential ERU of 2,700 square feet.

The major difference between a multifamily and commercial property is that the bill is typically distributed between a larger group of residents on a multifamily property than that of commercial. Again a sampling of 100% of multifamily residential properties was performed similar to that of the commercial properties from the Okaloosa County Property Appraisers database. The sampling included a range of properties from 0.02 acre to 19.39 acres with impervious areas ranging from 0.03 square feet to 227,505 square feet. Appendix C lists the multifamily properties in the City by their parcel identification numbers with their respective mapped impervious area and the number of ERUs based on the sampling from the Okaloosa County Property Appraisers database. The number of ERUs for each property is generated by dividing the impervious area by the residential ERU of 2,700 square feet. 6. 6 MISCELLANEOUS LAND USE 6. 6. 1 Introduction During the study it was found that then; were a variety of other property types that did not fall directly under the residential, commercial or multifamily categories. The data gathered from the Okaloosa County Property Appraiser consisted of a breakdown of the different types of land use therefore allowing the creation of an estimated amount of fee for each property type. 6.6. 2 Vacant Properties The data gathered from the Okaloosa County Property Appraiser consisted of many properties labeled as vacant. Vacant properties does not mean unimproved since many vacant properties can have impervious area on the site yet not be vacated. However, it is assumed that these vacant parcels do not have water service or do not have an active water system account with the City and therefore, will not be billed stormwater user fees. Should a property go vacant but keep its water system account active with the City, then the name on the water account will be billed stormwater charges. 6.6. 3 Government Properties All Federal, State, County and City owned property comprise this category of land use. The City of Fort Walton Beach will not be charged for any impervious areas that it owns. This is to keep from generating a useless paper trail. It is unnecessary for the City to generate a new budget line item to pay themselves a utility fee. The Federal, State, and County owned lands will be charged at a commercial rate for such properties as the U. S. Postal Office and the schools. Other government properties considered conservation or state park will be charged at a rate equivalent to that of vacant land.

Therefore the land owned and used by utility companies will be charged at a commercial rate. 6.6.6 Road Rights of Way Road Rights of Way in the City include a range of road areas. The statewide precedent for Stormwater Utilities studies has been to not include road right of ways in the funding of a stormwater utility. Area within the road right of ways is not considered in generating stormwater utility revenue for the City. 6. 7 PROJECTED REVENUE Based on the ERU determined in Section 4 of this report and the aforementioned basis for billing non -residential and non -commercial properties, ranges of utility rates were incorporated into a revenue database to determine a range of revenues available to the City for stormwater improvement funding. A default factor of 5% was incorporated into the revenue projections accounting for non -payment customers. The determined revenue ranges are not final and will need to be rectified with the final billing/collection methodology implemented by the City. Table 6 -2 includes the range of revenues for various utility rates in the City based on the Okaloosa County Property Appraisers database. Appendix D summaries ERU costs for existing Stormwater Utilities throughout Florida. Please note each utility is created using different ERU basis and each community structures stormwater utility costs in their own unique manner.
