Article 7: Subdivisio i <br /> Section 7.12: Flexible Developments <br /> 3) If the residential lots are proposed to be served by septic systems -- `Yield" <br /> plan shall show soil suitability for individual septic tanks by a • iminary soil <br /> ability analysis performed in the field on at least 50°. • the proposed lots with <br /> all of - •roposed lots located on a map showin• e location of soil types suited <br /> for septic s - s based on the Orange C•. y, N.C. Soil Survey. The soil <br /> suitability analyse :•d map shall be • -.ared by a Soil Scientist in consultation <br /> with the Soil Scientist o •- E •nmental Health Division of the Orange County <br /> Health Department. <br /> (4) The number of I• • achieved through _ 'reparation of a Conventional <br /> Subdivisio• •r"Yield" Plan is the number of • which must be used in preparing <br /> the able Development Plan. The number of lot not be increased through <br /> e proposed use of an alternative or community sewag- : •osal system. <br /> Increases are permitted, however, at the Preliminary Plan stag- here a more <br /> detailed soils analysis clearly demonstrates that a greater number o 2 is <br /> achievable than shown on an approved Concept Plan. <br /> (B) Design Process <br /> Flexible Development subdivisions shall be designed around both the Primary and <br /> Secondary Conservation Open Space Areas, which together constitute the total required <br /> open space. The design process should therefore commence with the delineation of all <br /> potential open space, after which potential house sites are located. Following that, <br /> access road alignments are identified, with lot lines being drawn in as the final step. <br /> This "four-step" design process is further described as follows: <br /> (1) Open Space Designation <br /> (a) All potential Conservation Open Space Areas, both Primary and <br /> Secondary, shall be identified using a S14e-site Analysis analysis#a <br /> map as described in Section 7.14.2(A)(3). <br /> (b) Primary Conservation Open Space Areas shall consist of those <br /> features described in Section 7.13.3(C)(1).7.12.4 <br /> (c) Secondary Conservation Open Space Areas shall comprise at least <br /> half of the remaining land and shall include the most sensitive and <br /> noteworthy natural, scenic, and cultural resources as described in <br /> Section 7.13.3(C)(2).7.12.4. <br /> (d) Guidance as to which parts of the remaining land to classify Secondary <br /> Conservation Open Space Areas shall be based upon on-site visits <br /> and the criteria contained in Section 7.13.8.7.12.4 <br /> (2) House Site Location <br /> (a) Potential house sites shall be tentatively located. <br /> (b) The proposed location of houses within each lot represents a <br /> significant decision with potential impacts on the ability of the <br /> development to meet the criteria contained in Section 7.13.87.12.4. <br /> (c) Generally, house sites should be located no closer than 100 feet from <br /> Primary Conservation Open Space Areas. <br /> (d) House sites may be situated 50 feet from Secondary Conservation <br /> Open Space Areas to permit the enjoyment of scenic views without <br /> negatively impacting Primary Conservation Open Space Areas. <br /> (3) Street and Lot Layout <br /> (a) Proposed streets shall be aligned to provide vehicular access to each <br /> house in the most reasonable and economical manner. <br /> Orange County, North Carolina—Unified Development Ordinance Page 7-59 <br />
