14 <br />1 that "EC 9.2751(1)(c) provides the applicable instrument for calculating density <br />z and excludes any reference to resident-only exclusivity." That may be true, but, as <br />3 noted above, "net density" is defined to include areas exclusively and actually for <br />4 residential use. The leasing office and maintenance shed do not fall within those <br />5 requirements. <br />6 The plain meaning of the terms "actual" and "exclusive" mean that the <br />7 residential use must be, in reality, the single or sole use performed by those <br />s buildings. See Webster's Third New Int'l Dictionary 22, 793 (see supra). Here, <br />9 the leasing office is used as a commercial component of the development to allow <br />1o applicants to apply for an apartment. Moreover, the leasing office is not "reserved <br />11 for the exclusive use of the residents in the development" because anyone can walk <br />12 into the leasing office to inquire and apply for an apartment. This is an undisputed <br />13 fact, as noted by LUBA: "Petitioners argue, and Lombard does not dispute, that a <br />14 nonresident may use the leasing office to inquire and apply to lease an apartment <br />15 and the maintenance building is also not reserved for the exclusive use of the <br />16 residents." ER-9-10 (LUBA Rec-14-15). The leasing office is very different from <br />17 an apartment within the development, which is reserved exclusively for residential <br />18 use. The leasing office is open to the public, and the leasing office is not a <br />19 common open space or a recreation facility. <br />
