This property has been identified in a FEMA(AE) Flood Hazard Area. SUBSTANTIAL IMPROVEMENT as defined in the
2018 International Building Code is any repair, reconstruction, rehabilitation, alteration, addition or other improvement of a
building or structure, the cost of which equals or exceeds 50 percent of the market value of the structure BEFORE the
improvement or repair is started. If the structure has sustained substantial damage, any repairs are considered substantial
improvement regardless of the actual repair work performed. The term does not, however, include either:
1. Any project for improvement of a building to correct existing health, sanitary or safety code violations identified by the
building and that are the minimum necessary to assure safe living conditions.
2, Any alteration of a historic structure provided that the alteration will not preclude the structure's continued designation as a
historic structure.
When Substantial Development has been determined future work including such items as change of use, additions,
alterations, and repairs are subject to the requirements of the 2018 International Existing Building Code and 2018
International Building Code Section 1612.
Mason County Flood Prevention Ordinance definition (MCC 14.22.040):
"Substantial improvement" means any repair, reconstruction, or improvement of a structure, taking place DURING A TEN-
YEAR PERIOD, in which the cumulative cost equals or exceeds fifty percent of the market value of the structure either:
(1) Before the improvement or repair is started,or
(2) If the structure has been damaged and is being restored before the damage occurred. For this definition "substantial
improvement"is considered to occur when the first alteration of any wall, ceiling, floor, or other structural part of the building
commences, whether that alteration affects the external dimensions of the structure.
This term includes structures which have incurred "repetitive loss"or"substantial damage" regardless of the actual amount
of repair work performed.
The term does not, however, include either:
(1)Any project for improvement of a structure to comply with existing state or local health, sanitary, or safety code
specifications which have been identified by the local code enforcement official, and which was in existence prior to the
damage event or improvement, and which are solely necessary to assure safe living conditions, or
(2)Any alteration of a structure listed on the National Register of Historic Places or a State Inventory of Historic Places.
All future work will be evaluated at the time and by scope and value.
* Compliance is required for protection of utility systems. Flood proofing can be achieved using several measures including
elevation, relocation, component protection, or other measures that provide partial protection. Different approaches can be
used to improve flood damage resis-tance.This is key in areas of repetitive, low-level flooding. The principles of these
measures apply with two key methods: elevation and component protection and can be accomplished at elevations higher
than the elevation required greater than the Base flood elevation or two feet above the highest adjacent grade. See flood
survey preformed prior to the clearing, grading or excavation for elevations.
The determination of Substantial Development for this project is at 47.9%. The value of the structure only (residence) is
$82,587 and value of the work is $39,587
No conversion of the lowest floor (under residence) is allowed. This area can only be used for storage.

Helical Pile Review for Structural Compliance
Date: October 20, 2023
Project Name: 18761 E St. Rt. 106- Foundation Stabilization Effort L120 Project#S230103-1XR
Project Location: 18761 E St. Rt. 106, Belfair, WA 98528
Client's Name:JJ Montoya, Project Coordinator—R&R Foundation Specialist, LLC
To whom it may concern,
The purpose of this letter is to confirm helical pile installation and capacity compliance with the structural
requirements specified in the L120 Structural Calculation Package and Structural Site& Foundation Plan dated
January 19,2023.
On August 28,2023,fifteen (15)helical piles were installed by R&R Foundation Specialists(R&R)to lift and stabilize
the residence located at 18761 E St. Rt. 106. Piles were installed with a DIGGA 10k drive head to a maximum depth
of 15ft.To the knowledge of L120,these piles were installed by R&R certified installers in accordance with the
cited structural package and ESR-3750. Please refer to the attached drive log provided by R&R.
With pile spacing at a maximum 8'-0"on-center,the minimum required vertical capacity as determined by L120
was allowable loadings of 12 kips per pile.These demand requirements are as determined and specified in L120's
structural calculation package cited above.
As required by the referenced structural package, proof testing was to be performed to 200 percent of the
specified design load. It is L120's understanding that the installers utilized the dead weight of the existing structure
to achieve the required reaction of a test pile.
Pile capacities for helical piles have been calculated utilizing the torque correlation factors provided in ESR-3750.A
torque/capacity chart detailing this calculation has been attached to this letter. Per the attached document, an
Ideal Foundation Systems 2-7/8in diameter 10k helical pile installed to minimum pressures of 900psi results in an
installation torque of 3,132 ft-lbs,and an allowable capacity of 14.1 kips including a safety factor of 2.
The results are summarized below:
Maximum Demand (allowable)=12.0 kips/pile
Available Capacity(allowable)=14.1 kips/pile
F26 •• •
By inspection,the pile capacities of the installed helical piles exceed the maximum loading demand or reached
refusal as determined by L120's analysis.Therefore,the installed piles comply with the structural design/demand.
Please contact us if you have any questions.

To Whom It May Concern,
The previous submitted calculation package for the foundation repair at 18761 E St Rt 106 on January 19,
2023 referenced helical piles 5, 6, & 9 with pile caps to stabilize and lift the residence. It was found that
these piles have concrete footings with CMU foundations and will no longer require pile caps.
Based on the analysis performed, it has been concluded that with the addition of L6x6x3/8 angle iron, the
reference removal of pile caps as requested is acceptable to perform lift on the structure with the previously
provided load requirements. Please reference the updated Level Survey for clarification.

SCOPEOF WORK FOUIHIDiA M WWMLW
Crew will install 3" Helical Piles,Angle Iron, 2'x2'x16" Pile Caps, as well as 4x4 PT Posts, and lift home to maximum practical
recovery. Crew will drive piles to a maximum 25'after there will be a$20 a foot charge per pile. Handheld only.Whomever
represents home will need be onsite for crew arrival and or job completion. Homeowner will pay deposit for structural engineering
and permit, once permit is issued 50%a deposit then 50%on completion. Homeowner has Geotechnica► Report that will be
amended to include Helicals. Crew may have to install adjustable Post Bases with pads at additional cost as needed.
L120 is in concurrence with pile layout recommended by R&R provided that the proposed layout is followed as marked and that a
maximum pile spacing of 8'-Vo.c.is achieved wl the installation of 4'segments of L6x6x3/8 angle iron.
NOTES:
1. It is acceptable to install piles at the spacing shown with t 0'-6"tolerance to allow for unexpected obstructions encountered
during pile installation provided that no two adjacent spans exceed the spacing limitation of 8'-0"o.c.
2. End piles are to be placed as close to corners as possible and shall not exceed a maximum corner distance of 1'-0"as marked.
3. Supplemental angle to be anchored to concrete with 5/8"diam Simpson Titen HD screw anchors @ 12"oc with a 4"minimum
