Since only the <br />Krovocheck parcel is contested in this action, only the Krovocheck <br />parcel was so analyzed. This analysis provides a basis of <br />comparison between the two zoning districts. <br />In analyzing the Krovocheck parcel, the staff considered its size, <br />configuration, and its physical characteristics. The staff also <br />assumed that no filling of the lagoon would be permitted, since <br />such filling conflicts with county regulations. While the total <br />size of the Krovocheck property is 6 acres, the one acre lagoon <br />reduces the property's effective size to five acres. <br />Besides size, design criteria incorporated in the county's plat <br />requirements were considered in assessing developability. These <br />criteria include access and right-of-way, stormwater management, <br />minimum lot width, and other standards. These criteria make the <br />difference between the potential number of lots allowed by a zoning <br />category and the actual number of lots that can be built on-site. <br />Since the Krovocheck parcel contains an existing single-family <br />residence and a lagoon, the lots created must be designed so that <br />both can be accommodated. With State Road A -1-A as the only access <br />to the parcel, the internal right-of-way must be platted within the <br />parcel to provide access to all created lots. Creating right-of- <br />way reduces the actual number of lots which can be developed. <br />Besides right-of-way, stormwater must be addressed sufficiently to <br />meet the county's requirements for systems outfalling into <br />Outstanding Florida Waters. <br />Based upon the analysis performed, staff determined that the <br />maximum number of lots that could actually be developed on the <br />Krovocheck parcel with the existing RS -3 zoning is 6 lots as shown <br />on Attachment #3. That number would decrease to 4 lots with the <br />proposed RS -1 zoning as shown on Attachment #4. Therefore, the net <br />result of the rezoning would be a two lot reduction in development <br />potential for the subject property. <br />Potential Impact on Environmental Quality <br />In comparing the present RS -3 zoning to the proposed RS -1, the <br />potential of environmental impact to the overall property's <br />resources does not substantially change. In that the upland <br />portion of the combined properties consists mostly of developed <br />area or undeveloped nuisance -exotic vegetation, the focus of <br />environmental concern is potential impact to the Indian River <br />Lagoon, shoreline fringe native vegetation, and the privately owned <br />16 <br />
