REVfEW COMMENTS ,
TO: Tim Grigsby - Inland Construction Company
FROM: Chris Reich - Engineering Development Services
SUBJECT: Alki Court Apartments
DATE: September 19, 1994 ,
A review of the above referenced project has been completed. The list below is a summary
of the items that need to be addressed by release of your building permit.
Road Plan
1. The design deviation for the substandard grades should be approved but the
following note should be added to the plan:
"All curb grades shall be verified by a licensed land surveyor prior to the pouring
of concrete. Discrepancies shall be reported to the County Engineer's Office
immediately." .
2. The low point in the vertical curve at station 5+ 60 is at Sta 5+ 52.39 at an
elevation of 26.14. Please revise the location of the grate. Please note that it
appears the grate will be within the approach and therefore a type 2 grate may
not be appropriate due to the hood. Provide calculations justifying a Type 1 will
handle the flow.
Drainaae Plan
3. Please indicate the right-of-way on Alki Avenue.
4. Provide openings in the landscape islands by buildings C and D or show the runoff
flow direction differently. As shown it appears the runoff will pond in these
corners. • "
5. A type 2 inlet shouid be provided under the sidewalk near Pond A.
6. The retaining walls are being reviewed under the design deviation process, further
comments may come from that review.
Please return the items marked "Original" with your submittal. All revised plans should be
submitted directly to the BUILDING DEPARTMENT along with necessary copies for circulation
to all reviewing agencies.
If you have any questions, please feel free to call.

The applicant or their representative is responsible for
including each item that is marked "Required By This Project" in
their submittal in accordance with the checklist descriptions.
Each item submitted that is to meet the checklist shall be
checked off by the applicant or their representative. Submittals
which do not conform to the above requirements will be returned
for further items with no review being accomplished. This will
prolong the review process. If changes occur in the requirements
for the project because of further conversations with Spokane
County representatives, please attach a note explaining the
agreed upon change in requirements. When the applicants'
submittal is finally approved, the Engineers department will
release their portion of the Building Permit.

the "proposal"; and the Boarci having held a de rlovo public hear-ing on the proposal on
March 29, 1994, having fully considered the public record files and the testimony and
documents presented, and further having individually visited or being familiar with the site
and vicinity in question; and the Board having rendered an oral decision on April 12, 1994,
approving the proposal with modifications, fiereby enters the following:
FINDINGS OF FACT
1. The property is generally located south of and adjacent to Alki Avenue and
.approximately 350 feet west of Pines Road (State Route 27) in Section 16,
Township 25 North, Range 44 EWM, Spokane County, Washington.
2. The proposal consists of a request for approval of a Zone Reclassification,
ZE-48-93, from Urban Residential-3.5 (UR-3.5) to Urban Residential-12 (UR-12)
for 5 multiple facnily dwellings on approximately .43 acres, and a Change of
Conditions, ZE-83C-82, for site plan review with request for bonus density in tfle
existing Urban Residential-22 (UR-22) zone, to allow 36 multiple family units on
an adjacent 1.4 acres. The total number of mulriple family units proposed is 41
units on 1.83 acres of land.
3. The Hearing Exanuner Committee held a public hear-ing on the proposal on January
20, 1994, subsequent to which by the Findings of Fact, Conclusion and Decision
dated January 24, 1994 the Committee approved the proposal.
4. Neighboring property owners timely appealed the Hearing Examiner Comrnittee's
decision to the Board in writing on February 2, 1994.
5. The legal requirements for public notice for the public hearing held by the Baard
have been fulfilled, based on ttle affidavits of mailing anci the testirliony at the
public hearing.
6. The Board takes official notice of the provisions of the Spokarie County
Generalized Comprehensive Land Use Plan (Comprehensive Plan), the Spokane
County Zoning Code (Zoning Code), the Spokane County Zoning C?rdinance, the
Program to Implement the Spokane Counry Zoning CodE (Comrnissioners'
Resolution No. 85 0900), and the Spokane County Code.
7. The owners of adjacent properties objected to the proposal based on lack of proper
notice, inadequate SEPA review, density, building height, noise irnpacts, increased
traffic, general incompatibility wi[h the surrounding neighborhood and other
concerns.
`
• .
BOCC FINDINGS ZE-48-93/ZE-83C-82 Page 3
18. The proposal is situated within the recorded fire service area of Fire Protection
District No. 1, and the Fire District has indicated it can provide adequate service to
the site.
19. While the SR 90/SR 27 interchange is cunently operating at a poor service level,
the Washington State Department of Transportation has not requested that
mitigation measures be imposed on the proposal to resolve this regional problem.
20. The proposal is located within the Central Valley School District. Upon
completion, the proposal will generate new students which will directly impact the
District's capital facilities. The District is currently operating over its capacity, and
will continue to do so when the proposal is fully developed unless additional
student housing is provided.
21. 'The applicant has indicated his willingness to enter into a voluntary agreement with
the Central Valley School District requiring the applicant to pay a per lot fee to help
finance the construction of additional portable or permanent classrooms, and
thereby mitigate the impacts of the proposal on student housing when developed.
The District's basis for deriving the amount of such proposed impact fees appears
reasonable.
22. Existing park facilities in the area of the proposal are inadequate. Upon development, the proposal wiIl generate addidonal residents which will directly
impact the County park system and increase the need for additional park facilities in
the area.
23. The applicant has indicated his willingness to enter into a voluntary agreement with
the County Parks Department to mitigate impacts from the proposal on the park
system arld to finance additional park facilities.
24. As conditioned, the proposal will not have a significant probable adverse irnpact
upon the public heal[h, safety, and general welfare.
25. The provisions of RCW 43.21C (The State Environmental Policy Act) have been
complied with and a Determination of Nonsignificance was issued. The appellant
raised objections to omissions in the SEPA checklist. Z'he record indicates that
these omissions were inconsequential to the envi.ronmental review process, as
explained by Planning Department staff at the public hearing. The Board concurs
with the Deternunation of Nonsignificance.
26. The proposal bears a substaneal relationship to the public health, safety and general
welfare.
27. Legal requirements have been met for rezone of the western .43 acres of the site and
for a change of conditions and bonus density for the eastern 1.4 acres of the site.
DECISION
The Board hereby approves the zone reclassification, chatlge of conditions and bonus
density requests for the site subject to the conditions set fordi below.

"208" POND VOLUMC CALCULA'1,lONS
'Ihe followuib pages contain data for each of tlhe ai-site drainabe basws, as well as data for zach
basin's "208" stormwater retention pond. Refer to tlhe 1" = 20' Drairlage hlap for die actual basin
locatious and bowidaries.
Iri general, for aay drainabe pond witli 3:1 side slopes, the pond volw»e can be calculaced with two
conipaaents: the volume directly above the pond floor plus the volume above the sida slopes. To
compute the volume at any pondinb depdi, only two parameters neod to be known: pond floor area
a,id pond floor perimeter 1ength.
Volume is calculated at 6" depth foc "208" treat,nent and at 8" depth for storabe, as follows:
At 6" depth:
Pond Volume =(0.5 ft. depdi x pond floor area) +(1/2 x 0.5 x 1.5 x pond floor peruneter)
0.5 Area + 0.375 1'erinieter
At 8" depth:
Poud Volume =(0.67 ft. depth x pond floor area) +(1/2 x 0.67 x 2.0 x pond floor peri,ik;ter)
= 0.67 A + 0.67 P
= 0.67 (Area + Perimeter)
2.0 feet

= 1.5 feet •
8" = 0.67 ft

DR:.AINAGE BASIN DATA SUMIVIARIES
AND
"208" POND VOLUME CALCULATIQNS
The foliowing pages contain data for each of the on-site drainage basins, as well as data for each
_ basin's "208" stormwater retention pond. Refer to the 1" = 20' Drainage Map for ttie actual basin
locations and boundaries.
In general, for any drainage pond with 3:1 side slopes, the pond volwtie can be calcu]ated with two
components: the volwne directly above the poud floor plus the volume above the side slopes. To
compute the volume at any ponding depth, only two parameters nead to be known: pond floor area
and pond floor perimeter length.
` Volume is calculaied at 6" depth for "208" treatment and at 8" depth for storage, as follows:
At 6" depth:
:Pond Volume =(0.5 ft. depth x pond floor area) +(1/2 x 0.5 x 1.5 x pond floor perimeter)
' = 0.5 Area + 0.375 Perimeter
At 8" depth:
Pond Volume =(0.67 ft. depth x pond floor area) +(1/2 x 0.67 x 2.0 x pond floor perimeter)
~ = 0.67 A + 0.67 P
= 0.67 (Area + Peruneter)
2.0 feet
~ 1.5 feet S" = 0.67 ft
6" = 0.5 ft.
