The Owner is in the process of acquiring the necessary approvals needed from various agencles to construct a 120 unit apartment building located at 2301 North Wilbur. Several submittals have been made to the Development Engineering Services section of Public Works for review and approval prior to obtaining "sign- off". The most recent submittal received comments dated February 28, 1994 listing several requirements needed before public Works would be prepared to approve the processing of a building permit. Mr. Bcb Florey (Owner's representative) requested that a partial permit be approved so that footings and foundations could be constructed while the final submittals could be made. IA an attempt to camply with this request and not create a hardship, this agreement was proposed and agreed to in concept. Public Works is willing to sign off on a partial building permit that allows for the construction of only footings and foundations until such time that all requirements have been met. In return for this sign off the Owner aqrees to the following: 1) All final documents complying with the comments made by Bob Turner dated February 28, 1994 would be submitted on or prior td Niarch 9, 1994. 2} No constructian beyond footings and foundations would be started until final approval was made on the last submittal. 3) Al1 engineering review fees on this pro3ect would be paid prior to any additional construction beyond footings and foundations. 4) A check zn the Amount of $5,000 would be made out to Spokane County as a statement of "good faith". This check would be held by Public Works until such time that. all items had been complied with and final sign- W 1026 Broaeiway Ave Spokane, Washington 99260-0170 (509) 456 -3600 FAX (509) 4564715 r~ ~ off achieved. If no other construction has been performed beyond footings and foundations the check would be returned to the Owner uncashed. Should any construction be performed beyond footings and faundatiQns without approval the check shall be forfeited. 5) The Owner recognizes that the approval to construct footings and foundations does not represent an approval that the locations and elevations of these items are adequate to allow for the construction of all features since Public Works has not been proviaed a complete set of final documents for review. The Owner agrees to hold the County harmless from any future claims due to this early start. Public Works will commit to a timely review as soon as the submittals are made. We would expect that our review would not take longer than one day and should all comments be adequately addressed a final approval would be made. This agreernent is entered into with the parties signed below and witnessed. ~ ~ . ~ - 1A B±-Il Lawson, Owner Dennis M. Scott,` P. E. • Director of Public Works . Witness!'

Site/area suitability and/or capability in relation to mining and proposed uses designated by the Plan. C. Comprehensive Plan ameadment projections for the subject area. D.

Growth inducements. 1. utilities 2. emplopment ceuters 3. supply/demand to residential lots C. Existing mining zone influences to land development. D. Proposed mining zone influences to land development. E. Site constraints to developement. 1. pipe lines 2. power lines 3. wildlife preserves F. Projected densitq and land use-tqpe distrzbution for 25 years. svn.r,.1,"` III. LAND USE COMPATIBILITY A. Visual comparison. 1. aerial photos of existing pits to other land use 2. aesthetic features of proposed operation B. Written evidence of compatibility. 1. zoning standards proposed 2. testimony of other schools to co-existence of mining activity 3. dust prevention measures 4. noise coatral measures The above-projected land use pattern would be used to assess future traffic and safetp impacts as provzded by Taylor Engineering. I estimate that the above information could be prepared and submitted f or agency review by January 15 - 30, 1990. !Alc.VA~~ r.,q 1~r o.~lC' VqNt't1IJV16"y-.% 1 . . ` - ~ , VD O ' C C. , '~o'~g Q4eAr* 40 C ,40 15 G• ~ C. wy5 nJ o ~ rc- ~ , - 0 ~ ~ i 1 1 A i { y- i I} - ' 1 ~ ~ ~ P 1 ~ 3t7 zs~ ~ 7 -Ae ~ ~ 1 ~ ~ ' • s ir b I I ~ ~1 - - _ I i ~ d , r - ~ i ~ - ` ~ I i p ` r 1I I I ~ I - - - N r b a ~ _ - - " t f~ I 1 N - - q ~ I ' • ' ~ 1~ wvr+-~ C~ ; 's• ~°r~-~°~^ N&es Iti~, s• 1~1oa.ob i, ~ ~ • ~ f ►OO %M 1= ra. 1x-Z.-e C-i- - - - - - ~ - - ti,.43( Oevyi~-ton - - - - ~ e.t ~ • _ _ _ _ _ e .5S_ ~Ytg~tn ~ A P~ t C.t ~ ~ - _ _ Z. ~~Cl ~r~~ rZ ~~G~trdS•'T1r~o~.v►_` ~ , ~ _ _ _ Tm~r c. ~ =~j~ p•~.'~s . ~ ~ . ~~H.~ _ ~?,s ~►~3 T r ~ cw~. ! - - - - ~ - ~ - ~ ~ ' T.~. t.k. ~o w~' 1 n- _ ~ a - - - D ~ ~ ra • , v~l~ ~ _ ~.Q. ~ ~tM.~.~~~M O~ ~o ~ , C ~~5'~'n ~ d~-tuczto~r~~~ ~ ~ , . a~n.~• -'T"n~JLc-k»- `~.rr.~.~~-~-r_c.. _ !~oc~a.~~ W 4 ww~ ~ ~ ~ ow~. ~ ~to•,-~-~ lc C~ ceR~ S_ ' ~ _ _ , ~ e . _ ~ ~ r _ - - - - ~e~~r.•~.'~e . _ _ ' z► ~ u,a.c~; ~d~wa~ 1 _ Corsct~~ ~'t. g~ - - be - ~'C~o~,~, 0' aLQ _ @ ~ _ _ _ ~ ~ Or7 V-4 ~ - - _ IUA . ~ ~ ~ c- h %q r OTICEi OF TRANSMITTAL nDDitEsS PttoJt:C:-t # q a~■~ D /\1 - ~ ~ I ~r ~~f+ • - _ ~ ■ 1 i-a/ BUSINCSS NA C PARGCL NO /LCGAL Jn ~1A C.t,t.c~ Apl.
