Reft Well and Septic Design for Lot 5; T16N, R1W, Section 24
To whom it may concern:
The 1 bedroom house will be served by a private well and septic system. The homeowner would
like to add a three bedrooms structure on to the residence; making a total of 4 bedrooms. A test
hole was excavated in the area of the proposed septic system. The proposed septic system will
be designed around the 30 foot radius of test hole. We are proposing that a 1250 gallon septic
tank and a five foot wide drainfield be installed. Comments regarding the proposed design are
summarized as follows:
1. SOILS: See the attached logs which shows the soil classifications, groundwater monitoring,
and the percolation test results. It is our opinion that the insitu soils should act as a sand filter and
that an application rate of 1.2 gallons/day/ft2 should be used.
2. TRENCH DESIGN:
a. Percolation Rate: <1 minutes/inch
b. Allowable Application Rate: 1.2 gallons/day/ft2
c. Number of Bedrooms: 4
d. Design Flow: 600 gallons per day _
e. Minimum Absorption Area: 500 ft2
f. Total Depth: 10 feet (max.)
g. Effective Depth: 4 feet
h. Width: 5 feet
i. Reduction Factor: 0.50
i. Minimum Length: 50 feet long
j Effective absorption area = 500 ft2
3. SURFACE WATERS: There are no surface waters within 100 feet of the proposed
upgrade.

4. 'TOPOGRAPHY: The majority of the property is mostly flat; in short, there are no slope
concerns.
We are unaware of any adverse impacts this installation would have on adjacent wells or septic
systems. If you have any questions, please contact us at 337-6179, or 244-9612. Thank you for

Standard Construction Specifications for Single Family Wells &
Onsite Wastewater Disposal Systems
I. REFERENCE PROPERTY:
Lot 5; T16N, R1W, Section 24. The design is for a four (4) bedroom residence
II. DEFINITIONS:
1. Property owner or homeowner: The legal property owner or his/her appointed representative
(not AWWC, Inc.).
2. Engineer: Alaska Water & Wastewater Consultants, Inc. (AWWC, Inc.)
3. Contractor: The company hired by the property owner to install the septic system. If the property
owner installs the system then he/she would also be the contractor for purposes of this installation.
4. Well Driller: The person or company hired by the property owner to drill the well.
5. DSD &/or MOA: Municipality of Anchorage, Development Services Department, On-Site Water
& Wastewater Program.
IlL RESPONSIBILITIES:
· Property Owner Responsibilities:
1. CONTRACTUAL RELATIONSHIP: The property owner shall contract with the contractor to
perform the work outlined in these specifications and plans, in accordance with the attached DSD permit.
There is no contractual relationship between the contractor and the engineer. The engineer shall inspect
the work, as required by DSD, so as to document the installation. Final acceptance of the contractor's
work rests with the mvner and the DSD.
2. SINGLE FAMILY RESIDENCE ONLY: This well and/or septic system design is for a single
family residence only. The homeowner is responsible for notifying the engineer if the residence is used as
a duplex, business, or multi-family dwelling. In such cases, the installation permit must be obtained from
the State of Alaska, Department of Environmental Conservation.
3. DISCLAIMER REGARDING AS-BUILT SURVEY: The validity of the design site plan is
limited by the accuracy of the as-built survey provided to the engineer by the property owner or his/her
representative. The property owner shall notify the engineer regarding any known inaccuracies associated
with the as-built survey. The engineer assumes no responsibility for the accuracy of the survey.
4. UNPLATTED EASEMENTS: The property owner is responsible for notifying the engineer
and the contractor of any unplatted easements, not shown on the as-built survey, which the new well or
septic system may encroach into. Such easements are typically identified in the property title report.
5. DISCLOSURE OF SITE CONDITIONS: The property owner shall notify the engineer and the
contractor of any seasonal groundwater or surface water runoff conditions known to him/her which could
potentially effect the operation of the septic system. The proposed septic system must be at least 100 feet
Page 1 of 7
AWWC, Inc., Year 2001
from any streams, ponds, creeks, swamps, bogs, or any other surface water as defined by the DSD. This
disclosure is of particular significance when the site evaluation and design work is being done during the
winter months when surface waters are frozen and there is snow cover.
The property owner shall notify the engineer and the contractor of any known subsurface conditions that
would prohibit or restrict the installation of the septic system. Items of concern would include, but are not
limited to buried piles of construction debris, undocumented septic systems, areas which consist primarily
of fill (imported) soil, subsurface drainage systems, & abandoned wells.
6. DRINKING WATER WELLS: The property owner is responsible for notifying the engineer
if, to his/her knowledge, any of the adjacent properties are used as a duplex, business, or multifamily
dwelling. The new septic tank and leachfield must be at least 100 feet from any private well, 150 feet from
any class "C' well, and 200 feet from any class "A" or "B" well, unless appropriate waivers are obtained.
Furthermore, the property owner shall notify the engineer of any undocumented or abandoned wells,
knoxvn to him or her, that are located on the subject or adjacent properties.
7. CURTAIN DRAINS: The new drainfield must be at least 20 feet doxvn gradient and 50 feet
upgradient from any subsurface drains. This includes foundation drains. The property owner should notify
the engineer of any such drains that are not shown on the design drawings for this installation.
8. POST CONSTRUCTION SITE RESTORATION: Unless specifically agreed upon other~vise,
the property owner is responsible for final grading of the areas which settle after construction. Prior to
awarding the contract, the homeowner should communicate to the contractor any expectations regarding,
but not limited to post construction site clean-up, re-landscaping, and restoration of any asphalt, fences,
trees, decks, ect. that are effected by the construction. All mound type drainfields are required by the
MOA to be re-vegetated. The property owner is responsible for this work unless other arrangements are
made with the contractor.
If the property is being sold, the property owner shall ensure that the aforementioned items are addressedi
with the buyer, and, if the work is to be completed after the sale of the property, that necessary funds arei
escrowed to fund the completion of the work.
9. PROPERTY OWNER INSTALLATION OF SEPTIC SYSTEM: If the property owner intends
to install the septic system he/she must first have obtained approval from the Municipality of Anchorage,
DSD (343-7904). Homeowner installations typically require more time for engineer inspections. The
homeowner should discuss the additional costs associated with such inspections with the engineer prior to
starting the project.
10. ENGINEER CHARGES TO INSPECT THE INSTALLATION: The property oxvner is
responsible for payment of all the engineer inspection charges. These charges are in addition to the soils
testing and design work that was required to obtain the MOA sewer/well permit. The number of
inspections will vary depending on the actual field conditions encountered and the construction methods
used. If there are any questions by the property owner, or his/her representative, regarding charges for
installation inspections they should be discussed prior to beginning construction. AWWC, Inc. will
provide you with a written copy of the fee schedule.
11. CHANGES IN THE SCOPE OF WORK: See Section V, "Disclaimers" regarding design
changes. See "Contractor Responsibilities", paragraphs 1, 2, & 13. In addition, see "Engineer
Responsibilities", paragraphs 2, 4, 8: 5.
· Contractor Responsibilities:
1. PRE-CONSTRUCTION LAYOUT: The contractor is responsible for locating all buried
utilities, easements, property lines, surface water setbacks, well radii, and water service lines which may be
encroached upon by the proposed septic system. The contractor shall ensure that all setbacks are flagged
by a registered land surveyor, or other appropriate means, prior to construction. AWWC, Inc. field
engineers/inspectors will not be responsible for establishing or confirming any of the aforementioned
setbacks.
Page 2 of 7
A WWC, Inc., Year 2001
The contractor should recognize that the location of all wells, surface waters, structures, and other items/
shown on the design drawings are typically derived from as-built surveys, and municipal records. The[I
as-built surveys and municipal records (prepared by professional engineers & land surveyors) have beeni
assumed to be accurate for purposes of this design; however, the accuracy has not necessarily been field~
verified. Prior to beginning any construction the contractor shall field locate all items which have1
protective setbacks and verify that there are no encroachment concerns. Any encroachments, for whichi
waivers have not been granted, should immediately be brought to the attention of the property mvner (ori
their representative) and the engineer.
The test hole pipes shall not be removed/abandoned until after the engineer has established their location
relative the new drainfield during the first inspection of the drainfield installation or during the
pre-construction layout. The new drainfield/s must be within a 30 foot radius of the test hole/s used for
establishing the design criteria.
The contractor should establish the elevation of all existing and proposed system components prior toi
starting construction so as to insure that the necessary grades can be maintained. This is particularlyl[
significant when the elevation of the existing system components is unknown because clean-outs are not~
IPresent, buried, or non-functional (can't measure down them because of obstructions). It is recognized that[I
[conditions can be discovered that will materially change the design and the construction costs.
2. DISCREPANCIES BETWEEN DESIGN DRAWINGS AND SPECIFICATIONS:
Construction shall be in accordance with the approved site plan and design drawings, and any special
provisions noted on the municipal sewer permit. The contractor is responsible for notifying the engineer of
any discrepancies noted on the design plans or drawings, prior to starting work.
3. CHECK GROUNDWATER LEVELS IN TEST HOLE MONITORING TUBES: Prior to
beginning construction, the contractor shall check the liquid level in the test hole monitoring tubes to
ensure that there has been no change in the groundwater levels that would impact the proposed design.
Any rise in the liquid level should be brought to the attention of the engineer so that design changes can be
made if necessary.
4. MAXIMUM DEPTH OF DRAINFIELDS: The maximum depth of the drainfield is shown on
the design drawings or is noted in the narrative portion of the design package. The contractor shall notify
the engineer of any inconsistencies noted in the design package.
For purposes of this installation, the maximum depth of the drainfield will be based upon taking a~
measurement at the deepest part of the excavation between the highest ground elevation encounteredI
(usually on the uphill side of the excavation) and the bottom of the trench or bed excavation. The1
contractor shall exercise caution not to remove evidence of the original grade prior to establishment of the1
total system depth. In short, don't remove the organic layer until after the original grade elevations areI
I
established by the inspecting engineer.
5. SUITABILITY OF MATERIALS USED FOR CONSTRUCTION. The contractor shall ensure
that all materials being used are in compliance with the most current guidelines established by the
Municipality of Anchorage. This includes, but is not limited to, the following:
a. Drainrock
b. Sand filter material for conventional beds, txenches, or mound systems.
c. Sand filter material and pea gravel for Intermittent Sand Filters (ISF).
d. Anchorage Sand and Gravel (AS&G) "block pea" material for Upflow Filters.
It is recommended that the contractor provide the engineer with current sieve analysis' from the
sand/gravel supplier to document the suitability of the material. The engineer assumes no responsibility for
ensuring that the materials delivered meet the MOA requkements.
6. BURIAL RATING OF TANKS: The contractor shall ensure that the septic tank, lift station, or
holding tank purchased has a burial depth rating suitable for the actual installation.
Page 3 of 7
AWWC, Inc., Year 2001
7. SEPTIC TANK AND STEP TANK SIZES: Prior to purchasing a septic tank or lift station the
contractor shall verify that it is adequately sized for the number of bedrooms shown on the permit issued
by MOA. The minimum septic tank size is 1000 gallons and the minimum STEP tank size is 1250 gallons.
These size tanks will handle residences with up to 3 bedrooms. For each additional bedroom over three (3)
the septic tank or the STEP tank volume shall be increased by a minimum of 250 gallons. For example, a
four (4) bedroom residence must have a 1250 gallon septic tank or a 1500 gallon STEP tank.
8. INSPECTIONS - ENGINEER NOTIFICATION: The contractor shall notify the engineer at
least 24 hours prior to starting construction. If deemed necessary, a pre-construction site visit shall take
place. The contractor shall coordinate with the engineer any inspections which will be required during
weekends, holidays, or before/after normal working hours (8:00 am to 5:00 PM). The property owner
may incur additional charges for inspections which do not occur during normal business hours. It is
the contractor's responsibility to notify the engineer a least 2 hours prior to any inspection.
9. REGULATORY NON-COMPLIANCE. The contractor shall report to the engineer and the
property owner any observed condition which would put the septic system in violation of State or
Municipal regulations.
10. BACKFILL OLD TEST HOLES: Any remaining test hole excavations shall be filled and
mounded as part of this project. Unless instructed otherwise by the engineer, the old test hole groundwater
monitoring pipes shall be removed.
11. FINAL GRADING FOR DRAINAGE: The contractor is responsible for final grading so as
to ensure that surface runoff does not adversely effect the septic system constructed, adjacent septic
systems, or adjacent structures.
12. SOIL COVER REQUIREMENTS: The contractor shall ensure that the final cover over the
tank and drainfield is either compacted adequately when backfilling, or mounded sufficiently to ensure that
there is adequate soil cover over the tank and drainfield after settlement occurs. If seasonal conditions
prevent this, the property owner (or his representative) shall be notified that additional fill may be required
after settlement occurs. This notification is of extra significance when the property is changing ownership.
13. CHANGES IN CONSTRUCTION COSTS: The contractor is responsible for obtaining
approval from the property owner for any additional construction costs associated with design
modifications or changing field conditions prior to doing the work.
14. WORKING IN RIGHT-OF-WAYS AND TRESPASSING PRIVATE PROPERTY: The
contractor is responsible for coordinating (including payment of encroachment permit fees) all access
through public and private properties with the appropriate authorities and/or property owners.
Furthermore, the contractor shall inform all parties of any potential impacts to adjacent properties prior to
beginning any construction.
15. MAINTENANCE & OPERATIONS MANUALS: The contractor shall provide the
homeowner with the manufacturer's installation/maintenance manuals for all system components installed
under this contract. If not given directly to the property owner, the manuals should be enclosed in a
protective cover (plastic bag) and placed/secured in a prominent location so the property owner can find it.
16. INNOVATIVE SEPTIC SYSTEMS. START-UP INSPECTIONS: The contractor shall
notify Anchorage Tank & Welding Company (272-3543) after the installation of an Intermittent Sand
Filter kit or Advantex system (supplied by Anchorage Tank) is installed so that the appropriate start-up
inspection can be scheduled. This notification also activates the quarterly maintenance schedule. Such
notification is usually not required for BioCycle installations since "BioCycle of Alaska" is typically
involved with the installation. The contractor shall contact BioCycle of Alaska (283-9003) regarding any
start-up notification requirements.
· Well Driller Responsibilities:
1. The well driller shall ensure that he has a well permit in possession prior to drilling the well.
2. The well driller shall physically verify that the there are no septic systems, or other potential
sources of contamination, within the protective radius of the proposed well prior to drilling it.

· Engineer Responsibilities:
1. SYSTEM DOCUMENTATION: The engineer is responsible for inspecting the installation of
the septic system and preparing as-built documentation, to the satisfaction of the M.O.A.. Inspections are
performed as necessary to document the construction of the system to the satisfaction of the M.O.A. In all
cases, inspections shall be performed as necessary to establish the following:
* The original grades at the drainfield/s site
* The bottom of all trench/bed excavation
* Top of sand on all sand filters
* Top of drainpipe
* Septic tank, or lift station, or holding tank prior to backfill
* Placement of filter fabric and insulation
* After final grading is completed
2. LIMITED AUTHORITY: The inspecting engineer has no direct authority over the contractors
activities or construction/safety practices. Should the engineer identify conditions which dictate a design
change, he or she will recommend that work be stopped, and/or the design be modified. If design
modifications are necessary, the engineer shall notify the property owner or his/her representative. The
inspecting engineer does not have the authority to direct the contractor to modify the system design in such
a way that it would be in violation of State or MOA regulations.
3. SEPTIC TANK INTEGRITY: The engineer shall inspect the condition of the existing septic
tank and determining its suitability for re-use. If the engineer determines the septic tank to be structurally
unsound, it must be replaced.
4. COORDINATION OF DESIGN CHANGES WITH THE MOA: If design changes are
necessary, the engineer will coordinate the approval of the changes with the MOA. The contractor does
not have the authority to proceed with any design modifications until verbal or written approval is obtained
from the MOA.
5. COORDINATION OF WAIVERS: If, during construction, it is determined that a waiver will
be required in order to install the system as designed, the engineer will apply for the necessary waiver/s to
the appropriate State or MOA regulatory bodies. The engineering services and State/MOA fees associated
with such waivers will be additional charges to the property owner, over and above the installation
inspection fees charged by AWWC, Inc.
SECTION IV. CONSTRUCTION GUIDELINES:
Construction shall be in accordance with the approved site plan and design drawings and any special
provisions noted on the municipal well and/or sewer permit. All materials, components, workmanship, and
construction practices shall comply with the Municipality of Anchorage's latest ordinances regarding wells
and septic systems, as well as DSD policies. The failure of the inspecting engineer to notice a material or
construction non-compliance does not relieve the contractor of his/her responsibili .fy to correct such a
deficiency.
· Septic Tank, Holding Tank, or Lift Station Installation:
1. The burial rating of the tank shall be adequate for the actual burial depth encountered.
2. The tank shall be level and sufficiently bedded to prevent settling or shifting of the tank.
3. All standpipes on the tank shall extend a minimum of 12 inches above final grade.
4. Tanks installed with less than 4 feet of cover shall be insulated. See "Contractor Responsibilities",
paragraph 12 regarding final soil cover.
5. The sewer service line from the house to the tank shall be sloped a minimum of 1/4"
per foot, unless prior approval is obtained from the engineer.
Page 5 of 7
AWWC, Inc., Year 2001
6. The inlet and outlet lines from the tank shall be bedded in drainrock or the soil shall be adequately
compacted to prevent future settlement of the soil.
7. A foundation clean-out will be installed ( 1-4 feet from the house) if one does not currently exist.
8. Post tank clean-outs shall be installed per MOA requirements. Does not apply to holding tanks or lift
stations with pressurized lines.
9. In high groundwater areas, all tanks shall be anchored to resist buoyancy forces when there is not
adequate soil cover to resist the uplift force. The engineer shall make this determination.
10. The final soil cover shall be graded so that there is positive drainage away from tank.
11. All holding tanks and lift stations shall have an audible and visible alarm inside the residence.
12. All lift stations shall be w~red in compliance with all MOA guidelines and the Uniform Electrical
Code. A municipal electrical permit and inspections must be obtained in areas where required by
the Municipality of Anchorage.
13. The contractor shall remove the old tank, or abandon it in compliance with the Uniform Plumbing
Code (UPC). The contractor is solely responsible for the abandonment procedure.
14. ISF AND ADVANTEX INSTALLATIONS: The control panel for the Intermittent Sand Filter and
Advantex systems shall be located outside the residence, for easy access during inspections. A
remote alarm must be installed inside the residence as per DSD requirements. Mounting the
panel directly to an exterior wood wall should be avoided because the closing of the relays creates
a "clanking" noise that may be offensive to the property owners.
15. ISF INSTALLATIONS: The air compressor shall be equipped with 0 to 10 psi gauge for the purpose
of monitoring air flow to the sand filter. The pressure gauge will be located so that it is easily
monitored by the property owner.
· Installation of Conventional Absorption Bed & Trenches:
1. Excavate the proposed bed/trench to the dimensions shown on the design. The bottom of the excavation
shall be within 2 inches of level (2 inch maximum variation between high and low spots). If the sidewalls
or bottom of the excavation become smeared, they must be raked or scarified before placement of the filter
sand or drainrock.
2. The trench or bed should be at least 5 feet from the test hole excavation.
3. All soil tests and excavation depths are advisory to the design and are to be verified in the field by the
engineer. If design changes are necessary, and the changes effect the contractor charges to the property
owner, the contractor shall obtain approval from the property owner prior to proceeding with the work.
4. Once the drainrock is installed, the distribution pipe is to be placed level (0.02 feet difference between
high and low shots) with the perforations faced downward. Drainrock is then to be placed over the
distribution pipe, to provide a minimum of 2 inches of cover over the pipe. The drainrock shall not be
pyramided over the drainpipe but shall be the same elevation over the entire trench/bed width.
5. A silt barrier must be installed between the final drainrock layer and the native soil backfill. The silt
barrier shall cover the entire drainrock surface.
6. Monitor tubes shall be installed at the locations shown on the design drawings, and extend a minimum
of 12 inches above final grade. The portion of the monitoring tube extending through the drainrock shall
be perforated from the bottom of the trench/bed to the invert of the distribution pipe.
7. Backfill over the £mal drainrock layer must not be less than 2 feet. Insulation must be installed when
the backfill depth is less than 3 feet. The insulation .qhall cover the entire width of the trench/bed, the
contractor shall "shoot" the final grades to ensure cover depth is adequate, prior to notifying the engineer
that the work is complete. The £mal cover over the drainfield must graded so that there is no potential for
water to pond over the trench/drainfield. See "Contractor Responsibilities", paragraph 12 regarding
final soil cover.
8. If an alternator valve was installed with this design the contractor shall provide a functional valve key to
the property owner.
SECTION V: DISCLAIMERS
Page 6 of 7
AWWC, Inc., Year 2001
· UNFORESEEABLE SITE CONDITIONS: The design of this septic system, prepared by AWWC,
Inc., was based upon a limited evaluation of the soil, groundwater, and site conditions. The extent of
the evaluation is consistent with standard engineering practice in the field. Furthermore, this design
was evaluated and approved by the engineers or technicians on staff at the Municipality of Anchorage,
DSD, based upon the information provided to them. Occasionally, during construction, unforeseeable
subsurface conditions (high groundwater, poor soils, buried debris,....) are encountered that make the
proposed installation not feasible. In such cases it is typically necessary to do more soils testing,
groundwater monitoring, and design work. These additional engineering services will be performed
on a fee basis at an hourly rate. AWWC, Inc. will obtain verbal authorization from the property
owner (or his/her representative) prior to proceeding with the work, and will provide a written estimate
if requested. The property owner should discuss with the contractor any changes in the installation
cost associated with the design changes.
· IF THE PROPERTY BEING SOLD AND FUNDS ESCROWED FOR THE UPGRADE, it is
important to bear in mind that the ability to upgrade the septic system on this property is not 100%
certain (for the reasons stated in the previous paragraph). There is always the possibility that
conditions could be encountered that would prevent the installation of anything other than a holding
tank. Although such a situation would be rare, it is important that all parties recognize that such a
scenario is possible.
· SEPTIC SYSTEM PERFORMANCE: The design of this septic system is based upon limited soils
testing, groundwater monitoring, and a visual assessment. It is possible that the actual soil conditions
are less favorable then the testing data indicated and that adverse, ~, changes in the
surface/subsurface water conditions could impact the performance of the system. Numerous other
factors, out of the control AWWC, Inc., may adversely effect the long term performance of the system.
Such factors include, but are not limited to, excessive number of residents in the house, plumbing
leaks, the use of septic system additives, failure to pump septic tank regularly, failure to alternate
drainfields (when this is an option), or/and excessive use of water. Given these variables, it is not
possible to warrantee the performance of a septic system.
By proceeding forward with this installation, the Engineer, Well Driller, Contractor,i
and Property Owner agree that they have read these specifications and agree to
accept the terms and conditions outlined in them.

Re: Nonconforming Determination
Dear Ms. Mills,
This letter is in response to your request for a determination of the nonconforming status
of the property located at 26301 Rusticate, Chigiak, Alaska. (Parcel :051-761-15, Grid
2065)
This determination is based on the following information:
The area in which the property is located was zone Unrestricted by the Greater
Anchorage Area Borough on March 11, 1965.
The property was zoned R-7, Intermediate Rural Residential District, by Anchorage
Ordinance 84-254, with an effective date of March 29, 1985.
The most recent survey of the property available in our office is Plat #86-63, which was
filed on April 29, 1986. That plat shows a 18'X18' house and a 14'X56' trailer home.
Municipal tax appraisal records show the cabin was built in 1970 and the trailer was
added in 1980.
An aerial photograph dated September 5, 1985 shows a cabin and mobile home on the
property.
The current R-7 zoning limits the number of principal structures on any lot to one.
The following conclusions can be drawn from the information above:
The presence of two principal structures on the property is a legal nonconformity
governed by AMC 21.55.030 and 21.550040.
I have enclosed a copy of the R-7 regulations and AMC 21.55 for your review and
information. Please call me at 343-8039 ifyouhave any questions.
Sincerely,
Richard A. Fern
Land Use Enforcement Officer
Municipality of Anchorage
21.55.010
21.55.010 Intent.
Within the zoning districts estabUshed by this
title or amendments that may later be adopted,
there may exist lots, structures, uses of land and
structures, and characteristics of use which were
lawful before the effective date of the applicable
regulations, but which would be prohibited, reg-
ulated or restricted under the terms of chapters
21.35 through 21.50 or future amendments. It is
the intent of this chapter to permit these
nonconformities to continue until they are re-
moved, but not to encourage their perpetuation. It
is further the intent of this chapter that
nonconformities shall n~t be enlarged upon, ex-
panded or extended, or be used as grounds for
adding other structures or uses prohibited else-
where in the s~me district.
Nonconforming uses are declared by this chap-
ter to be incompatible with permitted uses in the
districts involved. A nonconforming use of land or
a structure, or a nonconforming use of a structure
and land in combination, shall not be extended or
enlarged after the passage of the ordinance from
which this chapter is derived by the addition of
other uses of a nature which would be prohibited
generally in the district involved.
To avoid undue hardship, nothing in this chap-
ter shall be deemed to require a change in the
plan% construction or designated use of any build-
lng on which actual construction was lawfully
begun prior to the original effective date of adop-
tion or amendment of this title and upon which
actual building construction has been carried on
diligently. For purposes of this section, actual
construction is defined to include the placing of
construction materials in permanent position and
fastened in a permanent manner. Where excava-
tion or demolition or removal of an existing build-
ing has been substantially begun preparatory to
· rebuilding, such excavation or demolition or re-
moval shall be deemed to be actual construction,
provided that work shall be carried on diligently.
(GAAB 21.05.0702,)
21.55.020 Nonconforming lots of record.
A. In any district in which single-family dwell-
ings are permitted, notwithstanding limitations
imposed by other provisions of chapters 21.35
ANCHORAGE MUNICIPAL CODE
through 21.50, a single-f-mily dwelling and cus-
tomary accessory buildings may be erected on any
lot which is of record at the effective date of the
original adoption or amendment of applicable
regulations, except as restricted in subsection B
of this section. This prov/sion shall apply even
though such lot fails to meet the requirements for
the area or width, or both, that are applicable in
the district. Furthermore, setback and lot cover-
age requirements applicable to those nonconform-
ing lots of record shall be those of the zone with
the largest lot area requirement within which the
lot would be conforming. A lot which f, il.~ to be
conforming in any zone shall maintain a front
yard of 20 feet, side yards of five feet, a rear yard
of five feet, and a mwclmum lot coverage of 50
percent.
B. If two or more lots with continuous frontage
in single ownership and containing less than
6,000 square feet of area in each lot are of record
on November 27, 1990, and'are nonconforming by
virtue of this title or any amendment thereto, the
lands involved shall be considered to be an undi-
vided parcel for the purpose of this title, and no
portion of such parcel shall be sold or used which
does not contain a lot area of 6,000 square feet or
a lot width of 50 feet.

21.55.030 Nonconforming uses of land.
Where, at the time of the original passage of
applicable regulations, lawful use of land existed
which would not be permitted by the regulations
thereafter imposed by chapters 21.35 through
21.50, and where such use involves no individual
structure other than small or minor accessory
buildings, the use may be 'continued so long as it
remains otherwise lawful, provided:
A. No such nonconforming use shall be eh-
larged or increased or extended to occupy a
greater area of land than was occupied at
the effective date of adoption or amend-
ment of the relevant regulations.
B. No such nonconforming use shah be moved
in whole or in part to any portion of the lot

or parcel other than that occupied by such
use at the effective date of adoption or
amen&ment of the relevant regulations.
If any such nonconforming use of land
ceases for any reason for a period nf more
than one year, any subsequent use of land
st~-ll conform to the regulations specified
by ~hi~ title for the district in which such
land is located.
No additional structure not conforming to
the requirements of this title shall be
erected in connection with such noncon-
forming use of land.
21.05.070.C)
21.55.040 Nonconforming structures.
Where a lawful structure existed at the origi-
nal effective date of adoption or ,mendment of
applicable regulations that could not be built
under the terms of current regulations set forth in
chapters 21.35 through 21.50 by reason ofrestric-
tions on area, lot coverage, height, yards, location
on the lot, or other requirements concerning the
structure, such structure may be continued so
long as it rem.in, otherwise lawfid, subject to the
following provisions:
A. No such nonconforming structure may be
enlarged or altered in a way which in-
creases its nonconformity, but any struc-
ture or portion thereof may be altered to
decrease its nonconformity.
B. Should such nonconforming structure or
nonconforming portion of structure be dam-
aged by any means to an extent of more
than 50 percent of its replacement cost at
time of destruction, it shall not be recon-
structed except in conformity with the
provisions of this title.
C. Should such structure be moved for any
reason for any distance whatever, it shall
thereafter conform to the regulations for
the district in which it is located after it is
moved.
D. A residential structure in a residential
zone may be enlarged, so long as the
addition to the structure conforms to all
the requirements set forth in this title.
E. Not~,ithstanding subsections A through D
of this section, mobile homes may be re-
paired or moved within the lot in compli-
ance with setback and yard requirements'
if the mobile home occupied the lot at the
time of adoption of applicable regulations.
F. Notwithstanding subsections A through D
of this seedon, community interest and
local interest towers may be repaired and
~nnlnt. nlned in accordance with 21.55.060.B
of this chapter.

21.55.050 Nonconforming uses of structures.
If lawful use involving individual buildings or
· structures, or of a structure and premises in
combination, exists at the original effective date
of adoption or amendment of applicable regula-
tions cont-lned in chapters 21.35 through 21.50
that would not be allowed in the district under the
terms of current regulations, the lawful use may
be continued so long as it rem_nins otherwise
lawful, subject to the following provisions:
A. No existing structure devoted to a use not
permitted by orRinance in the district in
which it is located shall be enlarged, ex-
tended, constructed, reconstructed, moved
or structurally altered except in changing
the use nfthe structure to a use permitted
in the district in which it is located.
B. Any nonconforming use may be extended
throughout any parts of a building which
Were manifestly arranged or designed for
such use at the time of adoption or amend-
ment of applicable regulations, but no
such use shall be e~ended to occupy any
land outside such buildings.
C. If no structural alterations are made, any
nonconforming use of a structure and
premises may be changed So another non-
conf6rmlng use provided that the board of
ex,miners and appeals, either by general
rule or by mnklng findings in the specific
case, shall find that the proposed use is
more appropriate to the district than the
existing nonconforming use. In permit-

ting such change, the board of exnmlners
and appeals may require appropriate con-
ditions and safeguards.
D. Any structure and premises, in or on
which a nonconforming use is superseded
by a permitted use, shall thereafter con-
form to the use regulations for the dis-
trict, and the nonconforming use may not
thereafter be resumed.
E. Vfnen a nonconforming use of a structure
and premises is discontinued or aban-
doned for one year, except when govern-
ment action impedes access to the prem-
ises, the structure and premises shall not
thereal~er be used except in conformity
with the regulations of the district in
which it is located.
F. Where nonconforming use status applies
to a structure and premises, removal or
destruction of the structure shall elimi-
nate the nonconforming status of the land.
The term "destruction," for the purpose of
this subsection, is defined as dnmage to
an extent of more than 50 percent of the
replacement cost at time of destruction.

21.55.060 Repairs and maintenance.
A. On any nonconforming structure or portion
of a structure containing a nonconforming use,
work may be done in any period of 12 consecutive
months on ordinary repairs, or on repair or re.
placement of nonbearing walls, fixtures, wiring or
plumbing, to an extent not exceeding ten percent
of the current replacement cost of the nonconform-
ing structure or nonconforming portion of the
structure as the case may be. Nothing in this
chapter shall be deemed to prevent the strength-
enlng or restoring to a safe condition of any
building or part thereof declared to be unsafe by
any official charged with protecting the public
safety, upon order of such official.
B. Preexisting antennas and preexisting tow-
ers
1. Preexisting tower structures shall be al-
lowed to continue their usage as they
presently exist. Routine maintenance (in-

cludlng replacement with a new tower
structure of like construction and height)
shall be permit-ted on such preexisting
towers. New construction other than rou-
tine m~intenance on a preexisting tower
structure shall comply with the require-
ments of this ordinance.
l~otwithstanding abandon community in-
terest and local interest towers and/or
antennas, bona fide nonconforming tower
structures or antennas that are damaged
or destroyed may be rebuilt without hav-
ing to meet the separation requirements.
The type, height, and location of the tower
structure on-site shall be of the same type
and intensity as the original facility. Build-
ing permits to rebuild the facility shall
comply with the then applicable building
codes and shall be obtained within 180
days from the date the facility is damaged
or destroyed. If no permit is obtained or if
said permit expires, the community inter-

21.55.070 Uses permitted under conditional
use provisions.
A use existing before the original effective date
of applicable regulations that is permitted as a
conditional use in the district in which it is
located under the terms of this title shall not be
deemed a nonconforming use. Such use shall be
considered to ~.~t as a conditional use. The scope
of the conditional use shall be governed by the
· provisions of this chapter ~]n]ess modified by the
p]~nnlng and zoning commission in accordance
with section 21.15.030. A conditional use existing
before the original effective date of applicable
regulations that is permitted in its entirety as a
principal use in the district in which it is located
under theterms ofthi.~ title shall not be deemed a
nonconforming use. Such use shall be considered
to exist as a permitted principal use and the
conditional use shall be null and void.
