Assessor's Map No. 18-02-05-12 TL No. 2100 Springfield, Lane County, Oregon April 24, 2020 Project Narrative The applicant is proposing an in -fill development creating 6 lots within the subjectproperty shown as Tax Lot No. 2100 on Lane County Assessor's Map No. 18-02-05-12 and being commonly known as 4683 Union Terrace in Springfield Oregon. The subject property is approximately 0.9 acres in size and is zoned LDR, low density residential. The applicant is proposing to create a potential for 7 dwelling units which translates to a density of 8 units per acre. Per 3.2-205(A)(1) the LDR has a density range of 6-14 units per acre. The proposed development is in compliance with the density requirements of the underlying LDR zone. The site has frontage on Union Ave. along its entire northern boundary and approximately 84 feet of frontage on Union Terrace at the northeast corner of the property. The applicant is proposing to create a total of six lots that will front onto Union Avenue. Lot 1 will have approximately 59.4 feet of frontage on Union Avenue. Lot 2 will have approximately 59.2 feet of frontage on Union Avenue and 84 feet of frontage on Union Terrace. Lots 3-6 will access Union Avenue via a 20' paved private access drive. In accordance with SDC 3.2-220(3)(2), the access drive will be contained within a private 30.0 foot joint access and utility easement that will provide pedestrian and vehicular ingress and egress to and from the aforementioned lots, as well as providing for the orderly extension of private utilities to serve the aforementioned lots. These lot frontages either meet or exceed the lot frontage standards for LDR zoned property listed in SDC 3.2-215. Lot 1 fronts on an east/west street and contains 4,787 sq. feet which exceeds the minimum lot area requirement of 4500 sq. ft. for lots fronting on an east/west street as listed in SDC 3.2-215. Lot 2 is a corner lot with 59 feet of frontage on Union Avenue, an east/west street, and 84 feet of frontage on Union Terrace, a north/south street. Lot 2 will contain 6220 sq. ft. which exceeds the minimum lot area required for lots that front on either an east/west street or a north/south street shown in SDC 3.2-215. Lot 2 is a comer lot and also exceeds the minimum lot size needed to be classified as a duplex lot under SDC 3.2-215. The private access drive could be considered a north/south street. Lots 3-6 are all in excess of 6000 sq. ft., which exceeds the minimum lot area requirement of 5000 sq. ft. for lots fronting on a north/south street specified in SDC 3.2-215.
