diameter breast height of 8 inches, or, when there are multiple trunks, having a <br />minimum cumulative diameter breast height of 8 inches, considering the 2 largest <br />trunks measured at 4.5 feet above mean ground level at the base of the trunk or <br />trunks. <br />Solar Setback <br />The following information presents a proper solar setback calculation. The applicant provided an <br />improperly calculated solar setback calculation in public comment dated September 17, 2013. The <br />horizontal setback was presented as the distance from the current north property line to a point at grade <br />directly beneath the ridge of Building 1. There are two problems with that calculation. <br />The roof pitch is less than 5/12 (per elevations sheet A3.1 of application), thus according to <br />Eugene City Code (EC) Solar Setback Definition (EC 9.05) for shade point, the eave or more <br />accurately, the north facing dormer-style ridge located on the north wall of Unit 5 of Building 1 is <br />the proper shadepoint. The effective pitch from the dormer ridge to the ridge of Building 1 ridge <br />is still less than 5/12. Also the dormer ridge would cast the longest shadow at the azimuth on the <br />winter solstice and the dormer is greater than 3 feet wide (shade point definition). The applicant <br />stated that the ridge of Building 1 is the Shadepoint, which is inaccurate. Shade point definition <br />is presented below. Ridgelines and eaves of Buildings 1 and 2 are oriented almost directly east- <br />west. <br />The property line used in the setback measurement is the existing north property line, yet with the <br />approval of the Planned Unit Development, the right-of-way (ROW) of Oakleigh Lane will be <br />widened to 45 feet (22.5 feet each side of the centerline). The centerline will be the current north <br />property line of tax lot 400 (map 17 04 24 13) because the fu1120 foot ROW of Oakleigh Lane <br />was partitioned out of the original Oakleigh plat. Additional information regarding street <br />connectivity and diminished value of TL 200 due to anything less than a 45 foot ROW extending <br />to end of the existing Oakleigh street ROW, will be presented in follow-up public testimony. <br />Attached is the applicant's email with redline revisions indicating the above mistakes. <br />The shade point [SPH] (dormer on north wall) is 22.5 feet above existing grade according to AM (see <br />attached excerpt). N>90 feet so N=90, thus: <br />SSB = (2.5 x SPH) + (N/2) - 82.5 or <br />SSB = (2.5 x 22.5) + (90/2) - 82.5 or <br />SSB = 56.25 + 45 - 82.5 or <br />SSB = 18.75 feet (It should be noted that a follow-up calculation was presented by the applicant <br />which takes into account the 3 ft subtraction of the SPH due to the north-south trending ridge of <br />the dormer on the north wall, see below) <br />The proper setback from the existing north property line is (22.5 feet [ROW width] + 18.75 feet [setback <br />to shade point] + 2 feet [eave depth from wall] = 43.25 feet). Thus the distance from the existing north <br />property line to the north wall of proposed Building 1 (at the dormer) should be 43.25 feet. <br />Page 18 of 20 <br />
