In order to understand the scope of the work intended under a permit application and expedite the
issuance of a permit it is important that complete information be provided. When reviewing a plan
and it's discovered that required information has not been provided by the applicant, this will result -
in the delay of the permit issuance and in proceeding with building construction. The owner or
contractor shall be required to provide this information before the plan review can proceed. Other
plans that are in line for review may be given attention before the new information may be reviewed
after it has been provided to the Building Department.
Please review this document to determine if you have enough information to design your
project and provide adequate information to facilitate a plan review. Also, please consider
using a design professional for assistance in your design and a construction professional for
construction of your project. Any project with more than ten (10) occupants requires the plans
to be sealed by a Colorado Registered Design Professional.

Subject: Rockfall Simulation Analysis, Lot 1, Springridge Place 11, County Road
125, Garfield County, Colorado.
Dear Mr. Washburn:
As requested, we have performed a rockfall simulation analysis to evaluate the potential
impacts to the proposed development on Lot 1. We previously performed a
geotechnical review of the potential rockfall hazards to Lots 1-6 of the Springridge
Place II for the subdivision development (Hepworth-Pawlak Geotechnical, 2004). A
map of Lot 1 is shown on Figure 1. The Colorado Rockfall Simulation Program
(CRSP Version 4.0) was used to generate statistical probabilities for rockfall impacts to
Lot 1 based on the cross section location and profile shown on Figures 1 and 2. This
report presents the findings of the rockfall analysis, possible risk mitigation concepts, and
geotechnical parameters for risk mitigation design. The study was performed in
accordance with our agreement for professional services to you dated March 24, 2005.
PROPOSED DEVELOPMENT
The development plans for Springridge Place IT consist of 81 single family residential lots
having sizes ranging from about 1 acre to greater than 4 acres. Lot 1 is a 7.03 acre
property located uphill of County Road 125 on the western side of the Dry Park Valley.
The proposed residence will be a two story wood frame structure, The proposed building
envelope on Lot 1 is located on slopes of less than 25% and will be accessed by a private
driveway off of County Road 125. Water and sewer services will be from central systems
and the driveway grading is assumed to be minor.

ROCKFALL CI-IARACTER AND POTENTIAL
A field reconnaissance of the potential rockfall hazard areas was performed on May 24.
2004 as part of our previous review and again on April 6, 2005. Sandstone outcrops near
the top of the ridge on the west side of the property are potential sources of rockfall that
could reach the proposed building site on Lot 1. Sandstone blocks, many of which are the
result of previous rockfall events, are present near the proposed building envelope below
the sandstone outcrops. The sandstone blocks have maximum dimensions between about
2 to 31/2 feet and estimated weights of about 1/3 ton to 2 tons.
In our opinion, rockfall is still an active geologic process at this time under current
environmental conditions. However, without long-term observations, that are not
available, if is not possible to make rigorous statistical estimates of rockfall recurrence
frequencies in the proposed building area. The statistical recurrence frequency for rockfall
in this area is likely long and may be greater than 100 years. Although infrequent, if a
rockfall were to reach the proposed residence it could result in severe structural damage
and could present a life safety risk to the building occupants. If this risk is not acceptable,
then rockfall mitigation to reduce the potential risk should be considered. Possible
mitigation concepts are presented below in the "Rockfall Mitigation Concepts" section of
this report.
DESIGN ROCKFALL
The Colorado Rockfall Simulation Program (CRSP version 4.0) was used to develop
design rockfall parameters for possible mitigation structures located both 50 feet and 100
feet southwest of the proposed residence, see Figure 1. Results of the rockfall simulation
modeling at the west side of each of the possible mitigation structures are presented on
Tables 1 and 2. The modeling considered the dynamics of a 3.5 -foot diameter, spherical
rockfall traveling along the profile line shown on Figure 2. The values shown on Tables
1 and 2 are the highest values indicated by the rockfall size analyzed for the respective
structure locations. The design kinetic energy is associated with the 3.5 -foot diameter
rockfall. Attenuation coefficients used in the modeling were based on model calibration
that corresponds to the maximum rockfall runout for past rockfall observed in the field.
To account for possible structure overtopping, the minimum wall heights shown on
Tables 1 and 2 are the design bounce heights plus half the design rock block diameter,
assumed to be typically 3 feet.
Job No.105 261
Gtech
The choice of design parameters from Tables 1 or 2 to he used in the mitigation design
will depend on the risk level the owner is willing to accept. A relatively low exceedence
probability level is warranted considering that there is a significant safety risk to the
building occupants from rockfall.
ROCKFALL MITIGATION CONCEPTS
In the unlikely event that a rockfall were to reach the building area, it should be feasible
to reduce the risk by building lower on the lot or providing a catching structure located
upslope of the proposed home site. It should be possible to design the mitigation to
provide an acceptable level of protection to the building and its occupants, but some risk
of property damage is typically accepted by the lot owner.
A massive catching structure located up slope of the residence is commonly used in
western Colorado as a method of rockfall mitigation and could be a feasible type of
mitigation for the proposed residence. Two possible alignments of a mitigation structure
considered in our study are shown on Figures 1 and 2. The purpose of the mitigation
structure is to stop or deflect the design rockfall up slope of the proposed residence. A
wide flat approach bench located on the up slope side of the mitigation structure should
also be constructed for energy dissipation prior to a rockfall block impacting the wall.
The possible mitigation structures shown on Figures 1 and 2 are located 50 feet and 100
feet southwest of the proposed residence, respectively, but other alignments can be
considered. The rockfall dynamic parameters will change for other locations considered.
A conceptual cross-section of a possible earth structure, with a vertical up-slope face, for
rockfall mitigation is shown on Figure 3. The dynamic parameters of the design rockfall
will govern the size and height of the mitigation structure. The vertical up-slope face of
the structure can be achieved by using mechanically stabilized earth (MSE) or large
boulders.
In order to dissipate potential rockfall energy, the structure should be at least 8 feet wide.
As discussed above in the Design Rochfall section of this report, the uphill height of the
structure will depend on the level of risk that is acceptable to the owner. The uphill
approach bench behind the structure should be at least 15 feet wide. The cut slope along
the uphill side of the structure should be no steeper than 1.5:1 (horizontal to vertical) and
Job No.105 261

4 -
no higher than 15 feet. Depending on the alignment. location and elevation, a cut wall
may be needed in places to meet this grading criteria.
Limitations: This study was conducted according to generally accepted -engineering
geology principles and practices in this area. at this time. We make no warranty either
express or implied. The conclusions and recommendations submitted in this report are
based on our field observations, analytical modeling and our experience in the area. This
report has been prepared exclusively for our client to evaluate the feasibility and design of
rockfall mitigation. We are not responsible for technical interpretations by others of our
information. We should review the proposed mitigation plan when available to determine
if it is consistent with the intent of our recommendations presented in this report.
If you have any questions or if we may be of further assistance, please let us know.

1. The design rockfall parameters are based on a CRSP analysis of a 3.5 foot
diameter, spherical rock traveling along the profile line shown on Figure 2. The
CRSP attenuation coefficients were calibrated based on a model runout
comparable to the maximum runout distances of existing rockfall blocks observed
in the field.
2. 3.5 -foot diameter rock.
3. The minimum mitigation structure height is the design rockfall bounce height plus
one half the diameter of the design rock.
