To: ON-SITE WELL AND SEPTIC
From: THE REAL ESTATE DEPARTMENT
Re: DECOMMISSIONING SEPTIC TANK AND DRAIN FIELD SYSTEM AND WELL ABANDONMENT ON AT
6220 WEST 80TH AVENUE
In 2007 the Anchorage School District requested that the Heritage Land Bank purchase a parcel of land
adjacent to ASD managed property in the Westpark Subdivision area. ASD wanted the additional land to
meet the requirements for a joint middle and elementary school site. The requested parcel was Lot 1,
Kincaid West Subdivision and the improvements on the property included a residence that was built in
the mid-1960s with an on-site well and septic system. The property title was conveyed on September 4,
2007 and after the real estate transaction was completed, ASD requested the house be demolished. A
Hazardous Material Survey Report was commissioned and completed, identifying the need to abandon
the existing well and septic per ADEC requirements.
In 2009,the municipal Project Management and Engineering Department assisted the with the demolition
contract using one of their term contractors, Renegade Equipment, LLC, who further sub-contracted the
demolition to Alaska Demolition. The contract contained demolition, removal, and disposal of the septic
tank and drain field system, along with well abandonment.
In researching the documentation of the well abandonment and septic removal,we were able to find the
attached documents and photos, but no formal documentation or certification of the work that was
completed. With the lack of certifications or documentations, the Municipality of Anchorage proposes
the following process during clearing, grubbing or other site work that would anticipate development of
the property:
During site work, if the subject well casing is located, the well will be inspected
by a municipally certified well driller/pump installer for code compliance
regarding decommissioning wells. If the subject septic tank is located; it will be
removed.

Memorandum of Understanding
Between Municipality of Anchorage Departments
Project Management & Engineering and Heritage Land Bank
Regarding Building Demolition Work in Coordination with
Muirwood Area Storm Improvements (PM&E No. 06-37)
This Memorandum of Understanding shall serve to iterate an understanding between
the Municipality of Anchorage Department of Project Management and Engineering
(PM&E) and Heritage Land Bank (HLB) regarding building demolition work to be
completed on Municipality of Anchorage (MOA) property managed by HLB adjacent to
the project limits of the PM&E project identified as Muirwood Area Storm Improvements
(PM&E Project No. 06-37).
Project Background and Need:
During the construction of PM&E project in 2009, PM&E began discussions with HLB
about a vacant house located on the property at 6220 West 801h Avenue, Anchorage,
Alaska with legal description Kincaid West, Lot 1.
The house was constructed in mid-1960s and became vacant when HLB purchased the
property. The vacant house is considered a liability to the MOA because the
unoccupied structure could attract vandalism and become a public hazard.
The PM&E storm drain project cleared trees within the right-of-way that is adjacent to
the property, thereby enabling further public access to the house. PM&E and HLB
agreed that it was in the best interest of the MOA to demolish the building and to
expedite the work under the PM&E project construction contract. As anticipated, the
Anchorage School District (ASD) obtained management authority from HLB on
December 21 , 2009 . PM&E agrees to coordinate directly with HLB for the
reimbursement of cost of the building demolition work (Work).
Project Scope of Work:
PM&E agrees to manage the Work related to the building demolition on subject
property. The Work includes administration of professional services for obtaining
hazardous materials survey report (Report); and contract administration for construction
contract of the Work. The Report was prepared by EHS-Alaska, Inc on 10/27/09. The
demolition work was negotiated as a contract change order by the construction
contractor, Renegade Equipment, LLC, who is contracted for the storm drain project.
Memorandum of Understanding Between PM&E and HLB
Regarding Building Demolition Coordinated with PM&E Project No. 06-37
Page 2 of 3
The scope of work includes:
• demolition, removal, and disposal of: potentially hazardous containing materials
(as identified in the Report), all building materials associated with the building
infrastructure, and septic tank and drain field system;
• well abandonment;
• backfill of areas from basement and wastewater system; and
• decommissioning of utility services.
PM&E has reviewed the Renegade Equipment, LLC (RE) cost proposal to RFP No. 1 to
complete all work associated with demolition of the building. PM&E shall pay RE a
lump sum amount of $44,530.00. The work shall be in accordance with the Hazardous
Materials Report dated 10/27/09.
Project Cost Information:
The total project cost estimate is shown in Table 1 below. As previously discussed and
agreed, HLB will reimburse PM&E actual costs, not to exceed $50,000. PM&E will pay
all costs that exceed $50,000. PM&E will also pay all labor costs for construction
administration and inspection of the Work. PM&E's cost participation is justified due to
the fact that the Muirwood Storm Drain project significantly increased visual and
physical access to the abandoned building thereby creating an attractive nuisance and
associated risks. Demolition of the building is in the best interest of the MOA.

Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The existing septic system on the subject lot has failed and must be upgraded prior to
allow the completion of the parcel the lot is currently a part of. The future subdivision
will be called Kincaid West and this parcel will be' come Lot 1. We are therefore
requesting a permit be issued for the construction of a new septic system to serve the
five-bedroom home on the lot. The attached Site Plan and backup documentation
identify the location and configuration of the existing and proposed septic system. Also
identified on the plans are the locations of the existing well. The new subdivision will be
served by a community water system and no conflicts exist between the proposed
septic system and existing well and those on adjacent lots. Drainage arrows and
contour lines are shown indicating the current drainage patterns. The drainage patterns
will be maintained after construction. The existing septic tank and absorption trench
will be pumped, crushed, backfilled and abandoned in place.
The test hole placed on the lot indicated poorly graded gravel with varying amounts of
sand in the area of the new absorption trench. The percolation rate for this material is
between 1 and 5 minutes per inch. No groundwater was found dUring placement of the
test hole and none was noted during the monitoring period. We are therefore
proposing to place a new 1,500-gallon septic tank and a 63' long by 5' wide by 4'
effective depth absorption trench to treat the effluent generated in the house. The
elevation of the distribution line in the absorption trench will be 4' below the surface and
the total depth will be 8'. Sufficient fill will be placed over the trench and septic tank to
prevent frost penetration and possible freezing.
The ground surface on the lot slopes at shallow grades from east to west and north to

south. The trench will be constructed parallel with the slope as much as possible in
conformance with Municipal requirements. The new septic system will be constructed a
minimum of 100' from the existing well and any surface water in the area.
If the system is constructed in accordance with our design the following statements
apply:
]. The system, if constructed as designed, will hav(~ no adverse impact on the wells
in the area or those to be constructed in the future. The' new subdivision will be
served by a community water system.
The system, if constructed as designed, will have no adverse impact on existing
septic systems in the area or those to be constructed in the future.
The system, if constructed as designed, will have no adverse impact on reserve
space, either surface or subsurface, on any lots located in the area.
The system, if constructed as designed, will have no adverse impact on drainage
patterns in the area. The current drainage pattern will be maintained.
Sincerely,
Michael E. Anderson, P.E.
