G. The allowance of flexible lot configuration, including <br />zero lot line configurations for affordable housing. <br />Currently, the Board of County Commissioners may grant waivers from the residential <br />development standards found in Chapter 911 of the LDRs through the Planned <br />Development (PD) process established in Chapter 915 of the county LDRs. If granted, <br />these waivers can allow for development of small lot configuration, zero lot line and <br />reduced setback projects. The waiver criteria for the PD process are found in section 915.15 <br />of the LDRs and are provided below. <br />Section 915.15. <br />Planned development allowable waivers and development parameters. <br />(1) Conceptual P.D. plans shall list, for all areas and phases within the P.D. project area, theproposed <br />waivers and developmentparameters for the following: <br />a. Minimum lot size (in square feet); <br />b. Minimum lot width (in feet); <br />c. Minimum lot frontage (in feet); <br />d. Minimum yard setbacks for buildings: front, rear, and side; <br />e. Minimum yard setbacks for accessory structures (such as pools, patios, and decks); front, rear, and <br />side; <br />f. Maximum lot coverage; building(s) and impervious surface area; <br />g. Minimum separation distances between buildings; <br />h. Minimum right-of-way widths (by road type); <br />L Minimum open space per lot and by phase [Note: The minimum open space for the entire project shall <br />meet or exceed the requirements of section 915. 18.] <br />j. Minimum preservation/conservation area per lot. <br />Note: more conceptual plan submittal requirements are listed -out in section 915.22 <br />(2) Notwithstanding other provisions in this chapter (915) and Chapter 971, specific land use criteria <br />listed in Chapter 971 may be waived (modified or not applied) where such criteria would merely apply to <br />the compatibility of uses within the P.D. project area if approved by the county. Where specific land use <br />criteria apply to the relationship of a use(s) within a P.D. project and properties adjacent to the project <br />area, the specific land use criteria shall apply pursuant to the provisions of chapter 971. <br />(3) The conventional standards and criteria found in Chapter 911, Zoning, not covered in section <br />915.15(1) shall apply unless otherwise specifically waived or modified by other provisions of this chapter. <br />ANALYSIS: <br />Generally, the PD process serves as a mechanism whereby the county can approve projects <br />with reduced setbacks and/or mixed uses. The advantage of using the PD process instead <br />of traditional zoning is that an applicant can increase or at least maximize his development <br />project's density. In the PD process, however, there are development required trade-offs, <br />such as additional landscaping, which are required to gain the waivers for smaller lots and <br />higher yield. These trade-offs can have the effect of off -setting any housing unit price <br />reductions due to increasing yield. The county's small lot subdivision allowance, however, <br />provides for specific reduced lot sizes, and setbacks without requiring any specific waivers. <br />This is anticipated to be to a greater extent true with potential very small lot subdivision <br />regulations recommended by the AHAC and conceptually approved by the BCC on <br />February 18, 2020. <br />County Planning Staff are in the process of studying the inclusion of affordable housing as <br />a public benefit in the PD process.
