ZONE CHANGE january 30, 19 69
ZE-7-69 - AGRICULTURAL TO MULTIPLE FAMILY SUSURBAN: PLANNED UNIT
DEVELQPMENT* GUTHRIE INVESTMENTS,, INC.
Planning Commission Recommendation: ApQrove to Multipie Family
Suburban arid apQrove the Preliminary P.U.D. Plan (Mission Pines Medical Center
Developrnent sheets A-1, A-2f A-3 * and A-4 dated December 31, 1968) subject
to: 1) Relocation of the parkinq area to the rear or side of the nursinq home,
2) The future vi sitors' lodginA units be omitted from the plan f 3) The deline ation
of the sewaqe disposal facilit}r on the final plan as apQroved by the Spokane
3 County Health Department r 5) The extension and dedication of Vercler Road
northward alona the westerly_proaerty line to a point aareeable to both the
applicant and Spokane County Enqineer's office, and fi) The coacrete curb,
outter, sidewalk and driveway access paving (concrete asphalt) be delineated on
the final plan with a statement indicatinc{ these imiDroveraents are to be installed
at the applicant's expense.
A. R+easons:
1. Tbe proposed retirement home will be located in close prooNdmity to
the Valley Hospital and is situated on the periphery of a residential
neighborhood bounded by the Valley Freeway on the north. (In
addition to the Freeway boundary, the northern edge of the property
begins to slope rather sharply downward towards the Valley Free-
way. ) Therefore, the P1annLnq Commission finds that the property
is in a good locatian for Multiple Family Suburban zoning and
would be compatible to adjacent residential development. Also,
the Pl arming Commi s sion note s the development of the property
would be subject to standards set forth in tbe Planned Unit
Development section of the Zoning Ordinance which would further
the caripatibility of the proposed development to existinq residen-
tial improvements south of Mission Avenue.
2. The Planning Commission has already qiven prelimfnary approval
to a residential P. U. D. for pr+operty located immediately west of
the applicant's property (Alvin 1Nolff, ZE-40-67) which will have
to be revised if the present applicant develops the subject property
for a retirement home as indicated on his preliminary development
plan. The Planning Commission has taken action on the proposed
plan submitted with thi s application irre spective of P. U. D.
ZE-40-67.

3. The off-street parking area located in front of the retirement home
complex Ynust be relocatod for two reasons: a) off-street parking
area for non-residential uses are not permitted in the front yard
(the front 30 feet) of the Multiple Family Suburban Zone, and b)
sinqle family residences are located directly south of the proposed
complex acros s Mi s sion Avenue. The front yard area should be
landscaped with grass, trees, and shrubbery rnaintained by a
sprinkler system.
4. The sewaqe disposal system design and location should be approvec,
by the Spokane County Health Depa►rtment as delineated on the
final development plan. The P.U.D. plan for the property to the
west indicates a sewaqe lagoon treatment facility which was
originally designed to include the retirement units and a convales-
cent home.
5. The applicant should include in his final development plan the
location and width of pedestrian and vehicle circulation improve-
ments in accordance with the Spokane County Engineer's standards
for curbing, gutters, and sidewalk. In addition, driveway
entrances or exits should be shown from 25 to 30 feet in width
with a paved .apron between each entrance and existinq Mission
Avenue pavement.
The landscaping plan on Page A4 should be revised to include the
front yard as being permanently landscaped on the landscaping
plan for the subject property.
6. The applicant should be advised that the indicated "visitor uruts"
could not be operated vd thin the Multiple Family Suburban Zone as
they would constitute a matel use. Retirement hon►e units or
apartment units could be permitted if a Iater P.U.D. pian were
submitted amending the present plan. In thai event the plan would
have to provide a minimum of 10% of the total site as usable
common 'open space' land " as provided in Chapter 4.20.
7. Vercler Street should extend northward to a point which will
provide adequate public access to the adjacent property to the
we st a s well as to the s ubj ect property,
