11.13 House Rules. The Board or the Association membership is empowered to pass,
amend and revoke detailed, reasonable administrative rules and regulations, or "House Rules,"
necessary or convenient from time to time to insure compliance with the general guidelines of
this Article. Such House Rules shall be binding on all Unit Owners, lessees, guests and invitees
upon adoption by the Board or Association.
11.14 Rental Units. The Leasing or Renting of a Unit by its Owner shall be governed
by the provisions of this Section 11.14:
11.14.1 No Transient Purposes. With the exception of a lender in possession
of a Unit following a default in a Mortgage, a Foreclosure proceeding or any deed or other
arrangement in lieu of a Foreclosure, no Unit Owner shall be permitted to Lease his Unit for
hotel or transient purposes which shall be defined as Renting for any period less than thirty (30)
days. The Association may, by resolution of the Board, prohibit the Leasing of any Unit for a
period of less than six ( 6) months.
11.14.2 Entire Unit. No Unit Owner may Lease less than the Entire Unit.
11.14.3 Written Leases. All Leasing or Rental agreements shall be in writing
and be subject to this Declaration and Bylaws (with a default by the tenant in complying with this
Declaration and/or Bylaws constituting a default under the Lease or Rental agreement). The
Board shall be notified in advance of an Owner's intention to rent or lease a Unit. The Board
shall also be notified of the names of all occupants of the Unit being rented or leased.
11.14.3 Rent to Association. If a Unit is Rented by its Owner, the Board may
collect, and the tenant or lessee shall pay over to the Board, so much of the rent for such Unit as
is required to pay any amounts due the Association hereunder, plus interest and costs if the same
are in default over thirty (30) days. The renter or lessee shall not have the right to question
payment over to the Board, and such payment will discharge the lessee's or renter's duty of
DECLARATION OF
WHITWORTH CONDOMINIUMS
Page 27 of60
payment to the Owner for rent, to the ex lent such rent is paid to the Association, but will not
discharge the liability of the Owner or purchaser and the Unit under this Declaration for
assessments and charges, or operate as an approval of the lease. The Board shall not exercise this
power where a receiver has been appointed with respect to such rents. Other than as stated in this
Section 11.14, there is no restriction on the right of any Unit Owner to lease or otherwise Rent
his Unit.

ARTICLE 12
COMMON EXPENSES AND ASSESSMENTS
12.1 Estimated Expense. Within sixty (60) days prior to the beginning of each
calendar year, or such other fiscal year as the Board may adopt, the Board: shall estimate the
charges including Common Expenses, and any special charges for particular Units to be paid
during such year; shall make provision for creating, funding and maintaining reasonable reserve
for contingencies and operations, as well as for maintenance, repair, replacement and acquisition
of Common Elements; and shall take into account any expected income and any surplus available
from the prior year's operating fund. Without limiting the generality of the foregoing but in
furtherance thereof, the Board shall create and maintain from regular monthly Assessments a
reserve fund for replacement of those Common Elements which can reasonably be expected to
require replacement or a major repair prior to the end of the useful life of the Buildings. The
Board shall calculate the contributions to said reserve fund so that there are sufficient funds
therein to replace, or perform such major repair, to each Common Element covered by the fund at
the end of the estimated useful life of each such Common Element. The initial Board, whether
elected by Declarant or elected by Unit Owners, may at any suitable time establish the first such
estimate. If the sum estimated and budgeted at any time proves inadequate for any reason
(including non-payment for any reason of any Owner's Assessment), the Board may at any time
levy a further Assessment, which shall be assessed to the Owners according to Section 12.4.
Similarly, if the sum estimated and budgeted, and being collected and/or already collected, at any
time proves excessive, the Board may reduce the amount being assessed and/or apply existing
funds (in excess of current needs and required reserves) against future Assessments and/or refund
such excess funds.
12.2 Payment by Owners. Each Owner shall be obligated to pay its share of
Common Expenses and special charges made pursuant to this Article to the treasurer for the
Association in equal monthly installments on or before the first day of each month during such
DECLARATION OF
WHITWORTH CONDOMINIUMS
Page 28 of60
year, or in such other reasonable manner as the Board shall designate. No Owner may exempt
himself from liability for payment of Assessments for any reason, including waiver of use or
enjoyment of any of the Common Elements or abandonment of the Owner's Unit.
12.3 Commencement of Assessments. The Declarant in the exercise of its reasonable
discretion shall determine when the Association shall commence making Assessments; provided,
that in all events, Assessments shall commence on a date within 60 days of the date on which
seventy-five percent (75%) of the Units which may be created have been conveyed to Owners
(other than Declarant or an Affiliate of Declarant) or on a date not less than 60 days after the
recording of this Declaration, at the option of the Board. Until the Association makes an
Assessment, the Declarant shall pay all Common Expenses. After any Assessment has been
made by the Association, Assessments must be made against all Units, based on a budget
adopted by the Association; provided, until a date within 60 days after the date on which
seventy-five percent (75%) of the Units which may be created have been conveyed to Owners
(other than Declarant or an Affiliate of Declarant):
(a) the Board (whether elected by Declarant or elected by Unit Owners) may
elect not to collect monthly Assessments calculated as provided in Section 12.1 and instead elect
to collect and expend monthly Assessments based on the actual costs of maintaining, repairing,
operating and insuring the Common Areas; or
(b) the Declarant may elect to pay all of certain of such actual costs and have
Unit Owners pay a pro-rate share (based on each Unit's Allocated Interest) of the remainder of
such costs.
12.4 Allocated Liability. Except for Assessments under Sections 12.5, 12.6, 12.7 and
12.8, all Common Expenses must be assessed against all the Units in accordance with the
allocations set forth in Exhibit B. Any past due Common Expense Assessment or installment
thereof bears interest at the rate established by the Association pursuant to Section 12.12.12.
12.5 Limited Common Element. Any Common Expenses associated with the
operation, maintenance, repair, or replacement of a Limited Common Element shall be paid by
the Owner of or assessed against the Units to which that Limited Common Element is assigned,
equally.
12.6 Only Some Units Benefited. The Board may elect that any Common Expense or
portion thereof benefiting fewer than all of the Units must be assessed exclusively against the
Units benefited.
12.7 Insurance Costs. The Board may elect that the costs of insurance must be
assessed in proportion to risk.
DECLARATION OF
WHITWORTH CONDOMINIUMS
Page 29 of60
12.8 Utility Costs. The Board may elect that the costs of utilities must be assessed in
proportion to usage.
12.9 Assessments for Judgment. Assessments to pay a judgment against the
Association pursuant to RCW 64.34.368( I) may be made only against the Units in the
Condominium at the time the judgment was entered in proportion to their Allocated Common
Expense Liabilities at the time the judgment was entered.
12.10 Owner Misconduct. To the extent that any Common Expense is caused by the
misconduct of any Unit Owner, the Association shall assess that expense against the Owner's
Unit.
12.11 Reallocation. If Common Expense Liabilities are reallocated, Common Expense
Assessments and any installment thereof not yet due shall be recalculated in accordance with the
reallocated Common Expense Liabilities.
12.12 Lien for Assessments/Collection of Same
12.12.1 Lien. The Association has a lien on a Unit for any unpaid Assessments
levied against a Unit from the time the Assessment is due.
12.12.2 Priority. A lien under Section 12.12 shall be prior to all other liens and
encumbrances on a Unit except: (a) liens and encumbrances recorded before the recording of the
Declaration; (b) a Mortgage on the Unit recorded before the date on which the Assessment
sought to be enforced became delinquent; and (c) liens for real property taxes and other
governmental assessments or charges against the Unit.
12.12.3 Mortgage Priority. Except as provided in Sections 12.12.4 and
12.12.5, the lien shall also be prior to the Mortgages described in Section l 2. l 2.2(b) to the extent
of Assessments for Common Expense, excluding any amounts for capital improvements, based
on the period budget adopted by the Association pursuant to Section 12.1, which would have
become due during the six months immediately preceding the date of the sheriff's sale in an
action for judicial foreclosure by either the Association or a Mortgagee, the date of a trustee's sale
in a non-judicial foreclosure by a Mortgagee, or the date of recording of the Declaration of
forfeiture in a proceeding by the vendor under a real estate contract.
12.12.4 Mortgagee Notice. The priority of the Association's lien against Units
encumbered by a Mortgage held by an Eligible Mortgagee or by a Mortgagee which has given the
Association a written request for a notice of delinquent Assessments shall be reduced by up to
three months if and to the extent that the lien priority under Section 12.12.3 includes
delinquencies which relate to a period after such holder becomes an Eligible Mortgagee or has
given such request for notice and before the Association gives the holder a written notice of the
DECLARATION OF
WHITWORTH CONDOMINIUMS
Page 30 of60
delinquency. This Section does not affect the priory of mechanics' or materialmen's liens, or the
priority of liens for other Assessments made by the Association.
12.12.5 Recording as Notice. Recording of the Declaration constitutes record
notice and perfection of the lien for Assessments. While no further recording of any claim of lien
for Assessment under this Section shall he required to perfect the Association's lien, the
Association may record a notice of claim of lien for Assessments under this Section in the real
property records of any county in which the Condominium is located. Such recording shall not
constitute the written notice of delinquency to a Mortgagee referred to in Section 12.12.3.
12.12.6 Limitation on Action. A lien for unpaid Assessments and the personal
liability for payment of Assessments are extinguished unless proceedings to enforce the lien or
collect the debt are instituted within three years after the amount of the Assessments sought to be
recovered becomes due.
12.12.7 Foreclosure. The lien arising under Section 12.12 may be enforced
judicially by the Association or its authorized representative in the manner set forth in chapter
61.12 RCW. The Association or its authorized representative shall have the power to purchase
the Unit at the foreclosure sale and to acquire, hold, lease, mortgage, or convey the same. Upon
an express waiver in the complaint of any right to a deficiency judgment in a judicial foreclosure
action, the period of redemption shall be eight months. Nothing in this Section shall prohibit an
Association from taking a deed in lieu of Foreclosure.
12.12.8 Receiver. From the time of commencement of an action by the
Association to foreclose a lien for nonpayment of delinquent Assessments against a Unit that is
not occupied by the Owner hereof, the Association shall be entitled to the appointment of a
receiver to collect from the lessee thereof the rent for the Unit as and when due. If the rent is not
paid, the receiver may obtain possession of the Unit, refurbish it for rental up to a reasonable
standard for rental Units in this type of Condominium, rent the Unit or permit its rental to others,
and apply the rents first to the cost of the receivership and attorney's fees thereof, then to the cost
ofrefurbishing the Unit, then to applicable charges, then to costs, fees, and charges of the
foreclosure action, and then to the payment of the delinquent Assessments. Only a receiver may
take possession and collect rents under this Section, and a receiver shall not be appointed less
than ninety days (90) after the delinquency. The exercise by the Association of the foregoing
rights shall not affect the priority of preexisting liens on the Unit.
12.12.9 Mortgagee Liability. Except as provided in Section 12.12.3, the holder
of a Mortgage or other Purchaser of a Unit who obtains the right of possession of the Unit
through Foreclosure shall not be liable for Assessments or installments thereof that became due
prior to such right of possession. Such unpaid Assessments shall be deemed to be Common
Expense collectible from all the Unit Owners, including such Mortgagee or other purchaser of
the Unit. Foreclosure of a Mortgage does not relieve the prior Owner of personal liability for
DECLARATION OF
WHITWORTH CONDOMINIUMS
Page 31 of60
Assessments accruing against the Unit prior to the date of such sale as provided in this Section.
12.12.10 Lien Survives Sale. The lien arising under Section 12.12 shall not be
affected by the sale or transfer of the subject Unit except in the event of sale through Foreclosure,
as provided in section 12.12.9.
12.12.11 Owner Liability. In addition to constituting a lien on the Unit, each
Assessment shall be the joint and several obligation of the Owner or Owners of the Unit to which
the same are assessed as of the time the Assessment is due. In a voluntary conveyance, the
grantee of a Unit shall be jointly and severally liable with the grantor for all unpaid Assessments
against the latter up to the time of the grantor's conveyance, without prejudice to the grantee's
right to recover from the grantor the amount paid by the grantee therefore. Suit to recover a
personal judgment for any delinquent Assessment shall be maintainable in any court of
competent jurisdiction without foreclosing or waiving the lien securing such sums.
12.12.12 Late Charges. The Association may from time to time establish
reasonable late charges and a rate of interest to be charged on all subsequent delinquent
Assessments or installments thereof. In the absence of another established nonusurious rate,
delinquent Assessments shall bear interest from the date of delinquency at the maximum rate
permitted under RCW 19.52.020 on the date on which the Assessments became delinquent.
12.12.13 Attorney's Fees. The prevailing party shall be entitled to recover any
costs and reasonable attorneys' fees incurred in connection with the collection of delinquent
Assessments, whether or not such collection activities result in suit being commenced or
prosecuted to judgment. In addition, the prevailing party shall be entitled to recover costs and
reasonable attorneys' fee if it prevails on appeal and in the enforcement of a judgment.
12.12.14 Assessment Certificate. The Association, upon written request, shall
furnish to a Unit Owner or a Mortgagee a statement signed by an officer or authorized agent of
the Association setting forth the amount of unpaid Assessments against that Unit. The statement
shall be furnished within fifteen days after receipt of the request and is binding on the
Association, the Board and every Unit Owner, unless and to the extent known by the recipient to
be false.
12.12.15 Termination of Utility Services. If an Assessment becomes delinquent
the Board may notify the delinquent Unit Owner that unless the delinquent Assessment is paid
within ten (10) days (or such longer time as is specified in the notice) any or all utility services
furnished to the Unit Owner by the Association or under the Association's control will be
severed and will remain severed until the delinquent Assessment has been paid. If the
delinquency is not cured in the time specified the Board may take the action described in the
notice.
DECLARA T!ON OF
WHITWORTH CONDOMINIUMS

12.12.16 The remedies provided herein are cumulative and the Board may pursue
them, and any other remedies which may be available under law although not expressed herein,
either concurrently or in any order.
12.13 Acceleration of Assessments. In the event any monthly Assessment or special
charge attributable to a particular Unit remains delinquent for more than sixty (60) days, the
Board may, upon fifteen (15) days' written notice to the Owner of such Unit, accelerate and
demand immediate payment of all, or such portion as the Board determines, of the monthly
Assessments and special charges which the 13oard reasonably determines will become due during
the next succeeding twelve (12) months with respect to such Unit.
12.14 Delinquent Assessment Deposit; Working Capital
12.14.1 Delinquent Assessment Deposit
(a) A Unit Owner may be required by the Board or by the Manager, from
time to time, to make and maintain a deposit of not less than one(!) month nor in excess of three
(3) months' estimated monthly Assessments and charges, which may be collected as are other
Assessments and charges. Such deposit shall be held in a separate fund, be credited to the Unit
owned by such Owner, and be for the purpose of establishing a reserve for delinquent
Assessments.
(b) Resort may be had thereto at any time when such Owner is ten (I 0)
days or more delinquent in paying his monthly or other Assessments and charges. Said deposits
shall not be considered as advance payments of regular Assessments. In the event the Board
should draw upon said deposit as a result of a Unit Owner's delinquency in payment of any
Assessments, said Owner shall continue to be responsible for the immediate and full payment of
said delinquent Assessment (and all penalties and costs thereon) and thus the full restoration of
said deposit, and the Board shall continue to have all of the rights and remedies for enforcing
such Assessment payment and deposit restoration as provided by this Declaration and by law.
(c) Upon the sale of a Unit, the seller/Owner thereof shall not be entitled
to a refund from the Association of any deposit or reserve account made or maintained with
respect to such Unit pursuant to this or any other Section of this Declaration; rather, any such
deposit or reserve account shall continue to be held by the Association for the credit of such Unit,
and the Unit Purchaser shall succeed to the benefit thereof, and the Unit seller shall be
responsible for obtaining from the Purchaser appropriate compensation therefor.
12.14.2 Working Capital Contribution. The first purchaser of any Unit shall
pay to the Association, in addition to other amounts due, an amount equal to two (2) months of
monthly Assessments as a contribution to the Association's working capital. Such working
capital contributions shall not be used to defray Declarant's expenses in completing the
DECLARATION OF
WHITWORTH CONDOMINIUMS
Page 33 of60
construction of the Condominium, or to pay Declarant's contributions to Association reseives.
Upon the election of the first Board by Unit Owners other than Declarant, Declarant shall pay to
the Association as a working capital contribution an amount equal to two (2) months of monthly
Assessments for each of the Units then owned by Declarant. When a Unit owned by Declarant is
sold, Declarant may apply funds collected at closing from the Purchaser to reimburse itself for
funds paid to the Association for such contribution with respect to that Unit.
ARTICLE 13

13.l In General. Commencing not later than the time of the first conveyance of a
Unit to a person other than a Declarant, the Association shall maintain, to the extent reasonably

Association as obligee, in at least an amount equal to three months' aggregate Assessments for
all Units plus resetves, in the custody of the Association or Manager at any given time during the
term of each bond. Such fidelity bonds shall contain waivers of any defense based upon the
exclusion of persons who setve without compensation from any definitions of"employee" or
similar expression.
13.1.5 Insurance against loss of personal property of the Association by fire, theft
and other losses with deductible provisions as the Board deems advisable.
13.1.6 Such other insurance (including directors and officers liability) as the
DECLARA T!ON OF
WHITWORTH CONDOMINIUMS
Page 34 of60
Board deems advisable; provided, that notwithstanding any other provisions herein, the
Association shall continuously maintain in effect such casualty, flood and liability insurance and
a fidelity bond in compliance with the insurance and fidelity bond requirements for condominium
projects established by Federal National Mortgage Association, Government National Mortgage
Association, Federal Home Loan Mortgage Corporation, Veteran's Administration, or other
governmental or quasi-governmental agencies involved in the secondary mortgage market, so
long as any such agency is a Mortgagee or Owner of a Unit within the project, except to the
extent such coverage is not available or has been waived in writing by such agency.
13.2 Coverage Not Available. If the insurance described in Section 13. I is not
reasonably available, or is modified, canceled, or not renewed, the Association promptly shall
cause notice of that fact to be hand delivered or sent prepaid by first class United States mail to
all Unit Owners, to each Eligible Mortgagee, and to each Mortgagee to whom a certificate or
memorandum of insurance has been issued at their respective last known addresses. The
Association in any event may carry any other insurance it deems appropriate to protect the
Association or the Unit Owners.
13.3 Required Provisions. Insurance policies carried pursuant to this Article shall:
13.3.l Provide that each Unit Owner is an insured person under the policy with
respect to liability arising out of the Owner's interest in the Common Elements or membership in
the Association;
13.3.2 Provide that the insurer waives its right to subrogation under the policy as
to any and all claims against the Association, the Owner of any Unit and/or their respective
agents, employees or tenants, and members of their household, and of any defenses based upon
co-insurance or upon invalidity arising from the acts of the insured;
13.3.3 Provide that no act or omission by any Unit Owner, unless acting within
the scope of the Owner's authority on behalf of the Association, nor any failure of the
Association to comply with any warranty or condition regarding any portion of the premises over
which the Association has no direct control, will void the policy or be a condition to recovery
under the policy;
13.3.4 Provide that if, at the time of a loss under the policy, there is other
insurance in the name of a Unit Owner covering the same risk covered by the policy, the
Association's policy provides primary insurance, and that the liability of the insurer thereunder
shall not be affected by, and the insurer shall not claim any right of set-off, counterclaims
apportionment, proration, contribution or assessment by reason of any other insurance obtained
by or for any Unit Owner or any Mortgagee;
DECLARATION OF
WHITWORTH CONDOMINIUMS
Page 35 of60
13.3.5 Provide that, despite any provision giving the insurer the right to restore
damage in lieu of a cash settlement, such option shall not be exercisable without the prior written
approval of the Association, or when in conflict with the provisions of any insurance trust
agreement to which the Association is a part, or any requirement of law;
13.3.6 Contain no provision, (other than insurance conditions) which will prevent
Mortgagees from collecting insurance proceeds; and
13.3.7 Contain, if available, an agreed amount and Inflation Guard Endorsement.
13.4 Claims Adjustment. Any loss covered by the property insurance under this
Article must be adjusted with the Association, but the insurance proceeds for that loss are
payable to any insurance trustee designated for that purpose, or otherwise to the Association, and
not to any holder of a Mortgage. The insurance trustee or the Association shall hold any
insurance proceeds in trust for Unit Owners and lien holders as their interests may appear.
Subject to the provisions of Article 14, the proceeds must be disbursed first for the repair or
restoration of the damaged property, and Unit Owners and lien holders are not entitled to receive
payment of any portion of the proceeds unless there is a surplus of proceeds after the Property
has been completely repaired or restored or the Condominium is terminated.
13.5 Owner's Additional Insurance. An insurance policy issued to the Association
does not prevent a Unit Owner from obtaining insurance for the Owner's own benefit.
13.6 Certificate. An insurer that has issued an insurance policy under this Article
shall issue certificates of memoranda of insurance to the Association and, upon written request,
to any Unit Owner or holder of a Mortgage. The insurer issuing the policy may not modify the
amount or the extent of the coverage of the policy or cancel or refuse to renew the policy unless
the insurer has complied with all applicable provisions of Chapter 48.18 RCW pertaining to the
cancellation or nonrenewal of contracts of insurance. The insurer shall not modify the amount or
the extent of the coverage of the policy, or cancel or refuse to renew the policy, without
complying with the requirements of the Act.
13.7 Notification on Sale of Unit. Promptly upon the conveyance of a Unit, the new
Unit Owner shall notify the Association of the date of the conveyance and the Unit Owner's name
and address. The Association shall notify each insurance company that has issued an insurance

of the new Owner and request that the new Owner be made a named insured under such policy.

rebuild or restore the Building or improvements which suffered Significant Damage to
substantially the same condition in which they existed prior to the damage or destruction, with
each Unit and the Common and Limited Common Elements having substantially the same
vertical and horizontal boundaries as before. Modifications to conform to the then applicable
governmental rules and regulations or available means of construction may be made.
14.1.3 As used in this Article, the term "Emergency Work" shall mean that work,
which the Board deems reasonably necessary to avoid further damage, destruction or substantial
diminution in value to the improvements and to reasonably protect the Owners from liability
arising out of the condition of the Property.
14.2 Initial Board Determinations. In the event of Significant Damage to any part of
the Condominium, the Board shall prompt! y, and in all events within thirty (30) days after the
date of Significant Damage, or, if the Significant Damage did not occur at a particular

thereto employing such advice as the Board deems advisable:
14.2.1 The nature and extent of the Significant Damage, together with an
inventory of the improvements and Property directly affected thereby.
14.2.2 A reasonably reliable estimate of the cost to Repair the Significant
Damage, which estimate shall, ifreasonably practicable, be based upon a firm bid obtained from
a responsible contractor.
14.2.3 The anticipated insurance proceeds, if any, to be available from insurance
covering the loss based on the amount paid originally offered by the insurer.
14.2.4 The amount, if any, that the estimated cost of Repair exceeds the

DECLARATION OF
WHITWORTH CONDOMINIUMS
Page 37 of60
should be repaired.
14.3 Notice of Damage or Destruction. The Board shall promptly, and in all events
within thirty (30) days after the date of Significant Damage, provide each Owner, and each first
Mortgagee with a written notice summarizing the initial Board's determination made under
Section 14.2. lfthe Board fails to do so within said thirty (30) days, then any Owner or
Mortgagee may make the determination required under Section l 4.2 and give the notice required
under this Section.
14.4 General Provisions

required under this Article which has sustained Significant Damage shall be repaired promptly by
the Association unless: (a) the Condominium is terminated; (b) Repair would be illegal under
any state or local health or safety statute or ordinance; or (c) eighty percent of the Unit Owners,
including every Owner of a Unit of assigned Limited Common Element which will not be
repaired, vote not to Repair. If the Significant Damage is not to be repaired, the Board shall still
have authority to perform Emergency Work. The cost of Repair in excess of insurance proceeds
and reserves is a Common Expense.
14.4.2 Damage Not Restored. If all or any portion of the damaged portions of
the Condominium are not Repaired (regardless of whether such damage is significant): (a) the
insurance proceeds attributable to the damaged Common Elements shall be used to restore the
damaged area to a condition compatible with the remainder of the Condominium; (b) the
insurance proceeds attributable to Units and Limited Common Elements which are not repaired
shall be distributed to the Owners of those Units and the Owners of the Units to which those
Limited Common Elements were allocated, or to lien holders, as their interests may appear; and

their interest may appear, in proportion to the Common Element interests of all the Units.
14.4.3 Reallocation. If the Unit Owners vote not to Repair any Unit, that Unit's
Allocated Interests are automatically reallocated upon the vote as if the Unit had been
condemned under Article 15, and the Association promptly shall prepare, execute, and record an
amendment to the Declaration reflecting the reallocations.

pursuant to Section 14.4, then:
14.5.1 Contract and Contractors. The Board shall have the authority to
DECLARATION OF
WHITWORTH CONDOMINIUMS
Page 38 of60
employ architects and attorneys, advertise for bids, let contracts to contractors and others, and to
take such other action as is reasonably necessary to effectuate the Repair and restoration.
Contracts for such Repair and restoration shall be awarded when the Board, by means of
insurance proceeds and sufficient Assessments, has provision for the cost thereof. The Board
may further authorize the insurance carrier to proceed with Repair upon satisfaction of the Board
that such work will be appropriately carried out.
14.5.2 Insurance Trustee. The Board may enter into a written agreement in
recordable form with any reputable financial institution or trust or escrow company that such
firm or institution shall act as an insurance trustee to adjust and settle any claim for a loss in
excess of Fifty Thousand Dollars ($50,000), or for such firm or institution to collect the
insurance proceeds and carry out the provisions of this Article.
14.6 Decision to Terminate. In the event of a decision to terminate the
Condominium and not to Repair and restore damage and destruction, the Board may nevertheless
expend insurance proceeds and funds of the Association as the Board deems reasonably
necessary for Emergency Work (which Emergency Work may include but is not necessarily
limited to removal of the damaged or destroyed buildings and clearing, filling and grading the

BACKGROUND
The memorandum summarizes the civil requirements and design of the proposed
improvements to 407/409 Whitworth Avenue Project in Renton, Washington. The client is
proposing to demolish the current residences and outbuildings, replacing them with a new
five story multi-family building above an underground parking garage. The building will
include four floors of residential space and a ground commercial space and floor lobby
and 50 ground level and basement parking stalls. Attachment 1 shows the proposed site
plan. Table 1 summarizes the onsite areas.

*For this analysis we are assuming 100% impervious though the actual proposed
impervious may not be that high.
UTILITIES
There are existing connection to all utilities. The existing Storm Drain connection will be
adequate to service the proposed plan. The existing Sanitary Side Sewer Connection will
be upgraded to an 8" PVC pipe in order to service the additional units. The water service
will need to be upgraded in order to service the additional units as well as provide service
to the proposed sprinkler system. Conceptual FDC location and design is shown on the
plans.
GRADING
The parcel of interest is essentially flat and proposed improvements will match on site
grading. However, significant excavation will be required for the basement parking garage.
The estimated cut quantities is 5,639 cubic yards, which will be removed from the site. A
haul route and disposal site are to be determined.
STORMWATER DRAINAGE REQUIREMENTS
The City of Renton requires two types of runoff control for all projects that increase the
amount of impervious surface: Runoff Treatment and Flow Control (Detention). In
addition to the permanent runoff control requirements there are temporary runoff control
requirements during construction. Those requirements will not be addressed in this
memorandum, but will be met using Temporary Erosion and Sediment Control Best
Management Practices (BMPs) during future design stages.
Runoff Treatment
Runoff Treatment is only required for projects proposing 5,000 square feet or more of
pollution generating impervious surface. The project will only be creating approximately
336 square feet of pollution generating impervious surface. Since this is below the 5,000
square feet threshold, Runoff Treatment is not required.
Flow Control -Detention
Flow Control BMPs are required to prevent or control the excessive erosion that typically
occurs due to increases in peak flow rates and increases in the frequency and duration of
high flow conditions in urbanized watersheds. Flow control provides attenuation of storm
water flows through the use of infiltration or storm water detention.
10800 NE s" Strffit, Suite 150 B,;,ue .... e. WA 980C4 • {425) 451-4009 '--www.ost,omconSUWng.oom
The City of Renton requires that the a detention facility should be installed if the peak
discharge rates for 2 year, 10 year, or 100 year increase in excess of 0.5 cfs over the
existing storm and site condition discharge rates. Hydrologic analysis was completed to
determine if flow control was required.
Hydrologic analysis
The Santa Barbara Unit Hydrograph was used to predict peak flows for the existing and
proposed site conditions. Based on our calculations, results shown below, it was
determined that it is not necessary to install a detention facility. Table 2 Shows both the
existing and proposed Peak Flows for 2, 10, and 100 year storms and Table 3
summarizes the increase in peak flow rates of the proposed condition, which are all less
than the 0.5 cubic foot per second threshold for requiring detention. Therefore direct
discharge to city storm sewer is acceptable. See Attachment 2 for the SBUH
calculations.

CONCLUSION
The proposed multi family project can be engineered to function with the surrounding area
with no significant impact. The utilities, drainage, and grading design will include only
standard connections to existing infrastructure.
