Galena Street Aspen, CO 81611 RE: 160 Bulkley Drive Notice of Violation Dear Susan: Pitkin County issued a Notice of Violation to Jim and Kit Bulkley (the "Bulkleys") on July 29, 2011 related to changes made to the portion of the intermittent channel originating on the Celestial Land Co property that crosses through the Bulkleys' property (160 Bulkley Drive). Following the July 18, 2011 debris flow event, while the Bulkleys' yard was being cleaned up, work also was done on the channel by the Bulkleys' landscaper without first seeking an earthmoving permit. The Bulkleys have chosen to proceed with Option 2 presented in the Notice of Violation — to restore the channel to approximate previously existing conditions. At the Bulkley's request, I have reviewed the current conditions of the intermittent channel in order to determine what actions are necessary to restore the channel. On Friday, August 12, 2011, 1 met on site with County staff and Mark Hamilton (the Bulkleys' attorney) to review the work that had been done and what would be required to remedy the Notice of Violation. Based on review of available photographs, the approximate prior condition of the channel was ascertained. The plan is to return the channel to a state that functions as close as possible to how it would have functioned prior to improvement by the Bulkleys' landscaper following the July 18 debris flow event. In the days following that meeting, the Bulkleys had another landscape crew perform some of the work we had discussed. A portion of the south berm behind their carport was removed and lowered by hand and that material was placed back into the bottom of the channel where it had been located previously. I then re -reviewed the condition of the channel on Wednesday, August 17, 2011 and am using the channel's condition on August 17 as a baseline for any further recommendations concerning restoration. I have also had a chance to meet onsite and discuss the original channel work with the Bulkleys' contractor, Chris Preusch. Mr. Preusch has confirmed that debris from the July 18 event was removed from the main portion of the channel and the south berm was increased in height by 8- 12", using material removed from the bottom of the channel. Additionally, the upper portion of the channel was widened slightly. Material deposited outside the channel was cleaned up and some of that material was stacked along the outside of the channel. Based on available photographs of the site, evidence of the surrounding terrain and the comments from the Bulkleys' contractor, following is a plan for returning the channel to approximate its function of the channel prior to earthwork following the July 18 event: First, the upper reach of the channel has already been partially remedied (Figure 1). The additional height of berm added just below the fenceline has been removed and that material ASPEN GUNNI30N G.R.

The height of the berm is now equal to or less than that which existed previously and the bottom of channel elevation has been restored. But, the channel also was widened in this area (Figure 2). 1 therefore recommend that the side slope of that cut bank be filled and compacted to form a less severe cut condition along the north bank of the channel (Figure 3). Compacted earth topped with rock material will help resist erosion in smaller storm events and will approximate previously existing conditions. In the center portion of the channel, the current berm height is dose to original conditions (Figure 3). The large rocks were previously present, but some soil was filled around and over those rocks. Now that the soil has been pushed back into the bottom of the channel, present conditions along this section of the channel approximate prior conditions, as confirmed by photos taken after the July 18 event and my interview with the contractor. However, the lower reach of the channel (within the Bulkley property) still requires some further remedial work. As noted above, when debris from the July 18 storm was cleaned up, the south berm was raised 8"-12°. In order to approximate prior conditions, this section of the south berm should be returned to its original height by removing approximately 12° of berm height (Figure 4). Lastly, although the new earthwork did include re -seeding the area, erosion could occur even during small runoff events. The prior condition included some rock cover within the channel. During clean-up after the July 18 event, many of those rocks were removed and placed just outside the channel (Figure 5). Those rocks should be replaced within the channel to provide a similar level of erosion protection as was present previously. Some of the rocks should be embedded in the channel surface to provide additional stability. Obviously, larger events like those of July 18 frequently erode the channel and deposit new material. The actions suggested here to remedy the Notice of Violation and restore the channel to approximate its function prior to the recent earthmoving work do not imply that no future erosion or changes to the channel geometry or direction will occur. Rather, continuing changes to the channel are likely to result from future events. If needed, additional photos are available of prior and current conditions. I also am available to meet with the County to discuss this plan in more detail. Please let me know if we can provide additional information or be of further assistance.

As we have discussed, the Bulkleys have opted to restore the drainage channel on their property to approximate its pre -July 18 condition per Option 2 in the Notice of Violation letter from Catherine Berg to the Bulkleys dated July 29, 2011. Enclosed is a completed Earthmoving Permit application with regard to the same together with a check in the amount of $830.00 representing penalty fees at twice the normal rate of $415.00 per permit application.

Please feel free to contact either myself or Matt Webster at SGM should you have any questions. Please also note that this letter and application are being submitted one week after the August 12 deadline originally requested because the Bulkleys did not receive actual notice of the Notice of Violation until Monday, August 8, 2011 (since I was on vacation the week prior and the original certified letter from Ms. Berg was never delivered since it was sent to a physical address at which the Bulkleys do not receive U.S. Mail).

SUBJECT: Bulkley Compliance to the Notice of Violation Issued July 29, 2011 DATE: September 13, 2011 BACKGROUND On July 18, 2011 a mud and debris event occurred on the alluvial fan located along Maroon Bells Road which encompasses Bulkley Road and the residents in the area. On the afternoon of July 19, 2011, we (Peggy Bailey and Alaina Smith) toured the site to witness and photograph the results of the event. Some of the photographs taken on that day are included at the end of this memo. The event deposited material on the CLC property, the Bulkley Property, the Murdock Property as well as along Bulkley Road. Following the event, Mr. Bulkley hired an excavator to re -grade some of the deposited material in a manner which could alter and redirect the flow path of future runoff. Where material had naturally deposited in the vicinity of his carport, the ground was reshaped into a channel approximately 4 feet wide at the bottom with 2 feet horizontal to 1 foot vertical side slopes, and a depth of 2 to 3 feet. This was a violation of the Pitkin County Code as evidenced by a Notice of Violation (NOV) which was issued on July 29, 2011 to the Bulkleys. The NOV stated that one of two options were available to remedy the violation. The following excerpt is taken from the NOV: "1. An engineering report and analysis of the improvements shall be obtained and submitted to County Staff by Friday August 5, 2011. This report shall speak specifically to the potential impacts that the improvements may or may not have on all neighboring properties.

Prior to any remediation efforts an Earthmoving Permit application shall be submitted to the Pitkin County Community Development Department by August 11, 2011. The permit application shall include a fully engineered plan for remediation; this plan may be forwarded to the Colorado Geologic Survey for their review." On behalf of the Jim Bulkley, Matt Webster of Schmueser Gordon Meyer (SGM) submitted a letter dated August 26, 2011 to the Pitkin County Community Development Department "related to changes made to the portion of the intermittent channel " with a proposed remedy to the Notice of Violation. The letter does not discuss the implication of the impacts to neighbors but instead states that the Bulkleys have chosen Option 2 of the NOV (SGM, 8/26/11). In the SGM letter, Mr. Webster writes: "Based on available photographs of the site, evidence of the surrounding terrain and the comments from the Bulkley's contractor, following is a plan for returning the channel to approximate its function of the channel prior to earthwork following the July 18 event:" Mr. Webster describes an approach to "restore the channel to approximate previously existing conditions" which includes lowering the berm in one section below the carport and regrading (flattening) the channel bank along the north channel bank. It is Tetra Tech's position that without an accurate survey of the conditions immediately following the July 18, 2011 event, it is very difficult to fully remediate the area to post July 18`h conditions. Further, because it is not possible to restore conditions to 'natural', a detailed analysis would be necessary to evaluate the impacts the site modification has, and will have on downfan properties. Without modeling the area as it exists now and with the proposed changes, it is difficult to evaluate whether the proposed restoration to the altered topography will improve or worsen conditions downfan. SITE OBSERVATIONS AND SPECIFIC RECOMMENDATIONS Based on our observations of the July 18, 2011 event (made July 19, 2011), material deposited behind the carport (area of concern) in such a way that there was no defined channel.. A significant amount of material deposited that left no specific flow pattern. (Photo 1). In addition, mud and debris spilled (over the area that is now the elevated right bank) onto Bulkley Road uphill from the Bulkley's gate. Mud, rocks and debris traveled down Bulkley Road and towards the Murdock property before coming into contact with their timberwall. The misunderstanding in the SGM letter is that a channel existed in the area of concern following the July 18, 2011 event, when in fact no such channel existed. Photo 1, taken on July 19, shows the area of deposition prior to excavation efforts, Photo 2 shown the same area as it existed on Monday September 12, 2011. Photo 3 shows Bulkley Road where material had traveled after accessing the road uphill from the Bulkley's gate. Note that observations made on July 19`s indicate mud and debris material was deflected by the timber wall on the Murdock property to flow parallel to the wall. Photo 4 shows another location where material encountered the Murdock timber wall and was redirected. A similar subsequent mud and debris event may produce similar results if the area is again filled with debris, however, smaller events may be contained within the channel as it exists now and with the changes proposed by SGM.

County land use code does not allow for changes to ephemeral streams, however, perhaps an exception should be made as in this case where the alterations provide a potential benefit to property owners if the changes help to maintain historic flow patterns which thus far have not resulted in structural damage. The material that was used to raise the berm on the downhill side of the reconstructed channel as well as the material left in the bed of the channel is not armored, nor does it appear to be seeded or well compacted. This material is susceptible to transport in a clear water or mud flow, thus becoming entrenched and contributing to the volume of mud (as opposed to preventing mud from flowing on to the driveway). Therefore we recommend that Pitkin County accept SGM's proposed changes (lowering the berms and flattening the channel bank), and in doing so accept those changes as a modification to an ephemeral stream. We also recommend that the channel and banks be armored with suitably sized material, as noted in the SGM letter. Two additional observations related to the mud and debris event of July 18 were also made during our September 12 visit. First, there is a culvert that exists under the Bulkleys' gate on the uphill side of the road. The culvert is now completely buried (Photo 5). We recommend the culvert be cleaned out to allow for the intended conduction of surface water runoff. Secondly, the timber wall on the Murdock property has been increased in height since July 19. This wall is now 30" high and is solid along the approximate 9S ft length. The wall will mostly likely redirect flows in subsequent events which may or may not have negative impacts on downfan properties, however, it will most like increase depths along Bulkley Road, and perhaps alter flow patterns on downfan property. The unpermitted efforts which took place following the July 18, 2011 mud and debris event have altered the landscape (both the channelizing on the Bulkley property and the increased wall height on the Murdock property). The proposed remediation modifications may or may not increase hazards to neighboring properties. Therefore we suggest that Mr. Bulkley's engineer as well as an engineer for the Murdocks perform mud and debris flow evaluations to insure these modifications will approximate post July 18 conditions, specifically as it relates to impacts on downfan properties, including impacts to roads and homes. Whether this is a detailed modeling effort or a qualitative effort, we do recommend that the impacts of the channelizing and increased wall height are investigated to evaluate the impacts on Bulkley Road, Bulkley carport, Murdock residence and also on the Hoffberger residence. Thank you for the opportunity to review the proposed Bulkley compliance to the July 29, 2011 NOV. Please feel free to call us if you have any questions or which to discuss our recommendations.
