I THIRD ASSIGNMENT OF ERROR <br />2 EC 9.6780, as applicable site review approval criteria under EC 9.8445, <br />3 provides: <br />4 "Vision Clearance Area. Development sites shall have triangular <br />5 vision clearance areas on all street corners to provide for <br />6 unobstructed vision consistent with American Association of State <br />7 Highway and Transportation Officials (AASHTO) standards. (See <br />8 Figure 9.0500 Vision Clearance Area). Vision clearance areas <br />9 shall be kept free of all visual obstructions from 2 Y2 feet to 9 feet <br />10 above the curb line. Where curbs are absent, the crown of adjacent <br />11 streets shall be used as the reference point. These vision clearance <br />12 requirements may be adjusted if consistent with the criteria of EC <br />13 9.8030(11) of this land use code." (Boldface and underscoring in <br />14 original; emphasis added.) <br />15 In the third assignment of error, petitioners argue that because the <br />16 development will extend Lombard Street onto the subject property, EC 9.6780 <br />17 requires a triangular vision clearance area off-site at the corner of Lombard Street <br />18 and Fir Lane. Record 220 (vicinity map). Petitioners do not contend that Lombard <br />19 owns or controls the properties surrounding the intersection of Fir Lane and <br />20 Lombard Lane or that the intersection is otherwise within the "development site." <br />21 See EC 9.0500 (defining "development site").5 The development will create <br />5 EC 9.0500 defines "development site": <br />"A tract of land under common ownership or control, either <br />undivided or consisting of two or more contiguous lots of record. <br />For the purpose of land use applications, development site shall also <br />include property under common ownership or control that is <br />bisected by a street or alley." <br />Page 20 <br />
