This request is to amend an established building envelope on Lot 24, of the Maroon Creek Club PUD in order to accommodate the construction of a fourteen (14) foot tall retaining wall (as low as 8 feet in some areas) and a drainage system on the northwest portion of the property. The Applicant believes that the retaining wall is needed to stabilize the soil and prevent the proposed residence from slope failure. Additionally, the Applicant wishes to utilize a 24 inch wide drainage pipeline to route storm drainage around the proposed residence to the northwest ofthe existing building envelope. Therefore, the Applicant has requested approval of an insubstantial PUD amendment to amend the building envelope to transfer 723 square feet from the northeast and southeast corners of the existing building envelope and add 723 square feet to the northwest portion of the building envelope (please see attached application for exact location of proposed transfer). Included in the Applicant's proposal is a drainage study that was prepared by Resource Engineering Inc. The drainage study indicates that fill material was placed on the northwestern portion of the lot during the construction of Pfister Drive. The Applicant contends that aforementioned fill material is not stable and thus, necessitates the proposed retaining wall. Additionally, the drainage report indicates that one of the two natural drainage swales located on the propeity is in the center of the building envelope. Therefore, the Applicant requests to utilize the twenty four (24") inch wide drainage pipe mentioned above to redirect the natural storm drainage to the south and west of the existing building envelope. The Applicant intends for the proposed drainage pipe to empty out into a natural drainage swale on the western portion of Lot 23 of the Maroon Creek Club. Staff has reviewed the proposed application and visited the site to verify that the proposed building envelope adjustment would not significantly effect the natural vegetation on the property in which the building envelope was established to protect. Staff has verified that the area that is proposed to be included in the building envelope is mainly fill material and that the important natural drainage area on the 1 western extent of the property will not be negatively impacted by the proposed retaining wall. Additionally, the Community Development Engineer has reviewed the proposed drainage arrangement and feels that it is appropriate . The Parks Department has also reviewed the proposal and believes that the proposal will not significantly impact valuable native vegetation. In addition, the Applicant has received letters of support for the proposal from the owner of the neighboring Lot 23 and the Maroon Creek Club Master Association. Staff has proposed conditions of approval that require the Applicant to fence off the new building envelope during construction so that existing trees and shrubs outside of the building envelope will not be disturbed during construction as well as to place silt fencing as is noted in the drainage study during construction. Additionally, Staff is requiring that the Applicant record a building envelope adjustment plat with the County Clerk and Recorder's Office within 180 days of approval, after having the plat reviewed and signed by the Community Development Director and the Community Development Engineer. Building permits will not be issued until the plat is recorded. Staff has reviewed this proposed PUD amendment and recommends administrative approval by the Director, with conditions.

An Insubstantial PUD Amendment Application for Lot 24, Maroon Creek Subdivision Prepared by: Francis X.

Soil report from HP Geotech. 10. 24x36-inch Amended Plat map. I. INTRODUCTION Ducote Jax Holdings, LLC, the owner ofLot 24, Maroon Creek Club Subdivision, requests approval of an insubstantial PUD Amendment to permit the construction of a new single family residence for Wayne and Diane Ducote. The proposed amendment will change the configuration of the building envelope to allow the construction of a retaining wall on the downhill side of the residence. A retaining wall is required at the proposed location because the platted building envelope is located on an area ofunconsolidated fill material. The new building envelope will ~ remain the same size as the original building envelope. The proposed reconfiguration will result in a shift of 723 square feet from the northeast and the southwest corners of the envelope to the northwest side ofthe envelope. The Ducotes have been involved in the planning and design of their new home for approximately the past year. The pre-application conference was conducted with James Lindt on June 29, 2001. Since that conference, the City reviewed and approved amendments to the existing building envelopes in the subdivision as insubstantial PUD Amendments (approved 10-19-01). Unfortunately, the Ducotes were not aware ofthat review process or the conditions that resulted from it. Condition number one, in particular, provides that " 1. No development (including any landscaping) shall be allowed beyond the rear perimeter ofthe existing approved building envelopes oflots 21 through 24 (see Attachment "D" for areas to remain undisturbed). The Ducotes believe that this condition should not apply to their lot because the development of the home and retaining wall as proposed will not affect the natural drainage system or any existing wildlife corridor. This condition appears to have been required to protect the natural drainage system and to preserve an "important wildlife corridor" as identified by the City Natural Resources and Construction Manager, Steve Ellsperman. The protection of the natural drainage system has also been an important concern ofthe Ducotes and the Maroon Creek Club Master 1 Association. In consideration of these concerns, the project has been designed to carry drainage around the home and to return it to the natural system immediately below the home and retaining wall. The building envelope is located on a previously disturbed site that contains an unknown amount of fill dirt of indeterminate origin. Because ofthese existing soil conditions, the proposed location of the retaining wall is necessary to stabilize the existing slope and protect the future residence from potential slope failure. A drainage report from Resource Engineering and a soil report from HP Geotech are attached for ' reference. The proposed development should not affect any important wildlife conidors because the area immediately adjacent to this lot is blocked by large retaining walls for Pfister Drive. This project has been reviewed and approved by the Maroon Creek Master Association a letter from them is included with this application. This application also includes letters of support from the two adjacent lot owners. The Applicant has attempted to provide all of the material requested by the Staff. If additional information is required, the Applicant will make every attempt to provide the requested information. 2 2. INSUBSTANTIAL PUD AMENDMENT, SECTION 26.445.100 The Ducotes request approval of an Insubstantial PUD Amendment to reconfigure the building envelope for Lot 24, Maroon Creek Club Subdivision pursuant to Section 26.445.100 of the City Land Use Code. This section ofthe application will outline the Insubstantial PUD Amendment criteria and the Applicant's response to those criteria: Code: 66 X. PUD Insubstantial Amendments.

At the February 21, 2002 meeting of SARC, a request was made to SARC :0 grant Schematic [preliminary] Approval forlhe plans and to supporl the appl cant's proposed request to the Cityof Aspen for an insubstantial plat amendment to allow for re-configuratjon of the established building envelope. As it was presented to SARA Mr. and Mrs. Ducote propose to modify the building envelope to allow for 1) construction of a retaining wall and 2) removal / replacement of an area of deep fill outside of the envelopeinordertoaddressexisting drainageproblems and prevent furthererosion of theembankment. Since these itrprovements exceec 30' n height above existing grade, the plat amendment would apparently be required to accomplish them. SARC reviewed both the house design and the topographic and drainage issues involved with the request and asied you to provide the following additional information prior to any approvals: 1. -he consent of Mr. David Chamberlain as the owner of the adjacent Lot 25. The consentof the owner of the only other contiguous lot, Lot 23, had already been provided to the Committee with the application, 2.

RESOURCE ..... ~ENGINEERING INC. Mr. Jack Miller March 7,2002 Jack Miller and Associates PO Box 4285 Aspen CO 81612 RE: Drainage Study for Lot 24, Maroon Creek Club Subdivision Dear Jack: This letter report presents the drainage study for construction of a single family house on 1 Lot 24 of the Maroon Creek Club Subdivision near Aspen, Colorado. The drainage plan presented in this report provides for conveyance of off-site storm waterthrough the property and conveyance of on-site storm water consistent with the Master Drainage Plan for the Maroon Creek Club Subdivision. BACKGROUND Lot 24 is located on the hillside below Pfister Drive with slopes ranging from 10% within the building envelope area to 70% on the steep slopes to the west and north. The existing vegetation includes aspen and evergreen trees with gamble oak and service berry brush with various grasses. The soil is primarily Morval loam. However, fill material was placed on a portion the site during the construction of roads and infrastructure and rough grading of the site. There are two natural drainage swales across the property, both of which receive point source discharges of storm water from culverts under Pfister Driver. The western swale is away from the building envelope and is undisturbed by the proposed project. The central swale runs through building envelope and the storm water flow must be rerouted around the proposed house. The source of water for this swale is from a 24 inch culvert under Pfister Driver which conveys storm water collected from a relatively small offsite basin. It is proposed to route the drainage from the 24 inch culvert around the house and back into the swale at the north property line. RUNOFF Off-Site The off-site drainage basin tributary to the 24 inch CMP under Pfister Drive includes approximately 10.2 acres of forested and grassed hillsite, portions of two developed lots, and approximately 4,000 square feet of roadway. The rational method was used in calculating the peak flows for the two year and 100 year storm events. The two year flow is calculated at 0.84 cfs. The 100 year flow is calculated at 12.4 cfs. The assumptions and calculations are presented in the appendix. jm lot 24 drainage.890.wpd Consulting Engineers and Hydrologists 909 Colorado Avenue I Glenwood Springs, CO 81 601 1 [970]945-6777 I Fax (970]945-1137 Mr. Jack Miller March 7,2002 Page 2 Site The project site includes 0.604 acres. The two year peak runoff rate is calculated at 0.22 cfs. The peak 100 runoff rate is calculated at 1,6 cfs. The assumptions and analysis are presented in the appendix. Design Flow Since the 24 inch culvert under Pfister Drive has the capacity to convey the 100 year flow from the off-site basin, the pipeline through the property is likewise sized to convey the 100 year flow for the off-site basin plus the on-site basin. This is a conservative assumption since the peak flows do not coincide and approximately half of the site drainage will be conveyed thriugh the pipeline. The design flow is 14 cfs for the combined off-site and site drainage. DRAINAGE PLAN The overall drainage masterplan forthe Maroon Creek Subdivision provides forrouting the off-site and subdivision area drainage to Maroon Creek or through the golf course ponds consistent with the historic drainage patterns. The drainage from Lot 24 flows down the swales, into the large swale along the golf course (which includes the Willow Creek Ditch channel), into the golf course pond system, and eventually to the Roaring Fork River. The golf course ponds were designed to provide detention storage for up to the 100 year storm event. The drainage plan outlined below is consistent with the overall drainage master plan for the subdivision. The off-site drainage will be picked up in a 24 inch pipeline and routed around the house and discharged into the existing drainage swale consistent with the historic drainage pattern. The design of the pipeline will include water tight joints, manholes at the bends, and concrete inlet and outlet structures to anchor the pipe. The outlet structure will be designed to dissipate energy. The existing eroded gully will be stabilized by construction of a retaining wall and fill to reclaim the upper area, and rock riprap/vegetation to stabilize the gully below the outlet. A portion of the steep eroded portion of the gully is on the adjacent Lot 23 property. It is anticipated that the Lot 23 owner will cooperate in allowing stabilization of the eroded gully below the Lot 24 property line. The proposed location of the pipeline structure is shown on the attached Figure 1. The site drainage will generally follow the historic drainage pattern on the site. The general concept is to direct drainage away from the house structure. Area drains are proposed in the front of the house and in the rear of the house where continuous slopes or swales are interrupted by walk ways and retaining walls. These area drains will be connected into the proposed 24 inch drainage pipeline. The proposed site drainage concept is shown on the attached Figure 1. jm lot 24 drainage.890.wpd ..... ..... ..... RESOURCE ..... 11Ial ENG NEERING 1 nJ CJ Mr. Jack Miller March 7,2002 Page 3 Construction design documents including the pipeline profile, inlet, outlet, and manhole structure details will be developed for review and approval by the City of Aspen. EROSION AND SEDIMENT CONTROL Construction on the site will require implementation of erosion and sediment control measures. These include silt fence around the downstream perimeter of disturbed areas and installation of hay bales or erosion control logs in all drainage swales. The proposed location for erosion and sediment control measures are shown on the attached Figure 1. Details for construction of these items is also attached to the study. The erosion and sediment control measures must remain in place until all disturbed area are revegetated or stabilized. CERTIFICATION This report was prepared by Michael J. Erion, a Colorado Registered Professional Civil Engineer familiar with urban and rural drainage and flood control design and construction practices. The proposed drainage plan is consistent with the overall master drainage plan of the Maroon Creek Club Subaivision and will not cause damage to adjacent or downstream properties resulting from erosion, flood or environmental impact during construction and after completion.

The review was conducted to evaluate the feasibility of constructing a retamtig wall to elevate and level the site for the residence. The proposed concrete wall will be about 1() feet high and is needed roughly along the north building envelope line to build the residence. Borings 1 and 2, located just to the south of the proposed wall, encountered between 17 to 23 feet of fill material judged to be unsuitable for building support. We assume that the proposed building has been designed based on our preliminary recommendations for spread footings and that no more than 10 feet of compacted structural fill will underlie the footings. Based on our review, the proposed retaining wall appears feasible provided the existing fill is completely removed and the site elevalions are re-established as recommended in our previous report. Additional exploratory borings should be drilled to evaluate existing fill depths within the wall area and at other parts of the building for site specific foundation and grading design recommendations. If you have any questions or need further assistance, please call our office. Sincerely, HEPWORTH - PAWLAK GEOSJKHNICAL, INC. N rr Steven L. Pawlak, P.g.*: 1 5222 . 211~~ Rev.

The pipe is sized correctly and erosion control issues have been addressed. (1 think they could reduce the number of manholes but that's not our concern.) Retaining Wall: They could bring the west wing wall back towards the building by 10 to 20 feet. The elevation at the top of the retaining wall is 80 feet. On the east end of the retaining wall the wall rejoins the existing topography at elevation 78'. Similarly, the west end of the wall could be shortened to rejoin the existing topography at elevation 78'. (See attached drawing) A final note... With a little effort, I think the retaining wall might be eliminated. Only a small portion of the existing grade behind house is lower than the floor elevation of 81.5 feet. i \3 /JohnN/10124:MaroonCrkClub AREA i.. ./ -~-MOUND REBAR 540 â‚¬Te.â‚¬o RET+N'-4 ~\ RPC LS# 25947 j LOT 3 ~---fESÂ£- W BALES OR SILT FENCE ~ , EROSION CONTROL.

I have enclosed a preliminary site plan which delinestes the location of the residence, associated nat work, driveway and landscape screening, We have programmed large evergmens between our rwo properties whlch should provide adequate screening. Not only will the trees screen our driveways, they will also provide privacy for your property from our side terrace. We have also engaged a drainage engincer to propose a permanent solution to seasonal water runoff from the street Richard Wax and I have agreed to split this rernedial cost and the plan should eliminate existing drainage problems on your property. I believe we both want the same level of separation between our properties and if the landscaping shown on the plan proves to be inadequate. we will add more trees until wc achieve the desired effect I have also enclosed a copy of a letter prepared by my architect, Jack Miller, to the Maroon Creek Homeowners Association indicating your approval of our plan. If that is correct, I would appreciato your signing a oopy of this letter and I will have it picked up from you so that we can presÂ¢m that letter of no objection to the committee at the March 21't meeting.

INC 10.0.m~.1.01 LOT 24, MAROON CREEK CLUB SUBDIVISION -ILE: C LIEN[\890Â©UCOTE-SITE.dwg I ./ MEMORANDUM TO: Julie Ann Woods, Community Development Director FROM: James Lindt, Planning Technician GL RE: Revised Maroon Creek Club Subdivision Insubstantia] PUD Amendment DATE: October 16,2001 SUMMARY: The Maroon Creek Club Master Association, represented by Brooke Peterson, has applied for an insubstantial amendment to an approved Maroon Creek Club PUD to allow for areas outside the building envelopes the ability to be developed in a similar fashion to what is allowed in the current City of Aspen setbacks. The applicant is requesting to have the proposed amendment apply to lots 4,6 through 11,inclusive, 13, 14, 15,17 though 40, and 46 through 48 inclusive. The applicant is proposing that the areas outside of the approved building envelopes on the aforementioned lots be governed by city land use code section 26.575.040(A), Projections Into Required Yards, with the exception of subsections (A)(1) through (A)(4). Please see Attachment "C" for the city land use code section 26.575.040(A). BACKGROUND: According to some of the people involved in the original approvals for the Maroon Creek Club PUD, the original intention was that on the smaller lots within the PUD there was to allegedly be a "development envelope" approved between the building envelope and the lot lines that would allow development as described in the Maroon Creek Club Design Guidelines. However, the final recorded Subdivision/PUD plat did not show or reference "development envelopes" on these small lots and the Maroon Creek Club Design Guidelines were never signed by the County or the City, and are not recognized as an approval document. Therefore, over the past several years the City Zoning Officer has only allowed development outside the building envelope that is consistent with what is allowed outside the building envelope in the Pitkin County Land Use Code (under which the PUD approval was originally granted). The Maroon Creek Club Design Guidelines require that property owners do certain tree plantings outside the prescribed building envelopes. These non-native plantings directly conflict with what is allowed outside the building envelope under the Pitkin County Land Use Code's definition of a "building envelope". The applicant is requesting that the PUD be amended to allow for Section 26.575.040(A.)(5) through 26.575.040(A)(8) (Attachment "C") to govern the areas between the building envelope and the lot lines on the aforementioned lots. 1 STAFF FINDINGS: Staff finds that lots 4, and 6 through 11 should not be amended administratively because they already contain platted "development envelopes" that allow for non- native landscaping and retaining walls to be developed within the development envelopes. Staff feels that the proposed amendment may be inconsistent with the character of the original approvals in that it is clear that these lots already contained specific areas in which to plant non-native landscaping(Development Envelopes). The applicant may seek approval for this amendment through a review by the Planning and Zoning Commission. Lots 14 and 15 are the parking lot parcels that are already landscaped and don't contain building envelopes. Lots 17 and 18 are the Townhome Lots that are already governed by City Setbacks. With regards to lots 13,25 through 40, and 46 through 48, staff finds that these lots have already been graded and landscaped outside of the building envelopes, in conflict with the requirements for building envelopes in the Pitkin County Land Use Code. Staff finds that the City of Aspen Setback Regulations as proposed in this application would be more appropriate than building envelopes on these specific lots because many of the lots have been developed beyond the scope of what a building envelope is intended for. Building envelopes are typically set up to protect pristine, untouched areas or to preserve wildlife migration corridors which for the mostpart no longer exist on these lots. City Natural Resources and Construction Manager, Stephen Ellsperman, finds that some valuable native areas do exist within lots 19 through 24 and has recommended that a condition be placed on the amendment that would restrict the approval to only allow for Section 26.575.040(A)(5) through 26.575.040(A)(8) to only apply outside the building envelope as far back as the rear of the approved building envelopes on these specific lots. A drainage area that abuts the rear of lots 19 through 24 has been identified as an important wildlife conidor by Stephen Ellsperman. Ellsperman has also indicated that this drainage area remain undeveloped and untouched. Ellsperman has also indicated that some native tree plantings would be acceptable on vacant Lots 19 and 20 for the purpose o f screening the gol f course, but cautions that the planting should be limited and informal to maintain the "open feel" of the meadow. Though we will not regulate a specific landscape plan, we do recommend that the City Forester be consulted for tree placement at the time of landscaping. The City Engineering Department also has concerns about utility and emergency service personnel's access between the building envelopes. The Engineering Department recommends that a condition be placed on the amendment that puts the applicant on notice that any landscaping or retaining walls developed outside the approved building envelope will be allowed at the owner's risk and expense, and that if utility or emergency service personnel need to access the approved building envelopes that they will have the right to do so without preserving the non-native landscaping and improvements. 2 Staff has reviewed this proposed amendment and recommends that the Community Development Director administratively approve the proposed amendment with conditions on Lots 13, 14, 15, 17 through 40, and 46 through 48. APPLICANT: Maroon Creek Club Master Association, represented by Brooke Peterson, Kaufman & Peterson. LOCATION: Lots 13,14,15,17 through 40, and 46 through 48 included in this approval. ZONING: R-15 PUD REVIEW PROCEDURE: Insubstantial amendments to an approved PUD may be approved by the Community Development Director, pursuant to Section 26.445.100. STAFF COMMENTS: Review criteria and Staff Findings have been included as Attachment "A". The application has been included as Attachment "B". City of Aspen Land Use Code Section 26.575.040(A) has been included as Attachment "C". A map of the area to remain undisturbed is included as Attachment "D". RECOMMENDATION: Staff recommends the Community Development Director approve with conditions this Insubstantial PUD Amendment to allow for the area between the building envelopes and the lot lines to be governed by Section 26.575.040(A)(5) through 26.575.040(A)(8), "Projections Into Required Yards", of the City of Aspen Land Use Code on lots 13,14,15,17 through 40, and 46 through 48. APPROVAL: I hereby approve this Insubstantial Amendment on lots 13, 14, 15, 17 through 40, and 46 through 48 of the Maroon Creek Club PUD as proposed with the following conditions. 1. No development (including any landscaping) shall be allowed beyond the rear perimeter of the existing approved building envelopes of Lots 21 through 24 (see Attachment "D" for areas to remain undisturbed). 2. Ifremoval of landscaping or a retaining wall is required outside of the approved building envelopes for either utility personnel or emergency services to access through the subject lots, the utility and/or emergency services personnel will not be responsible for replacing the landscaping or retaining walls. The owner shall be responsible for bearing the cost of the replacement landscaping or retaining walls. 3 3. Trees that are located outside of the approved building envelopes on Lots 21 through 24 shall not be removed without a tree removal permit issued by the City of Aspen Parks Department. 4. Any landscaping to the rear of the building envelopes on lots 19 and 20 shall be approved by the Maroon Creek Club Master Association in consultation with the City Forester prior to planting to ensure that the landscaping will remain open and informal adjacent to the gol f course.

Ms. Julie Ann Woods, Director Mr. James Lindt, Zoning Enforcement Officer - June 25, 2001 Page 2 2. Pre-Application Conference Summary. Enclosed please find the Pre-Application Conference Summary prepared by James Lindt. 3. Fee Agreement. Enclosed please find the Fee Agreement with the City duly executed by Gary Albert, President of the Maroon Creek Club Master Association. 4. Property Owner's Consent. Enclosed please find a Consent Letter duly executed by Gary Albert as President ofthe Maroon Creek Club Master Association. By virtue ofthe provisions of the Protective Covenants for the Maroon Creek Club Master Association, copies ofthe relevant sections of which are enclosed. the Maroon Creek Club Master Association is granted all of the powers set forth in Colorado Revised Statute 3 8-33.3-302 (a copy of which is also enclosed), which includes the power to "institute, defend, or intervene in litigation or administrative proceedings in its own name on behalfof itself or two or more unit owners on matters affecting the common interest community". As I discussed with John Worcester. we submit that the authority set forth in the Protective Covenants and relevant statutes allow the Maroon Creek Club Master Association the ability to process this application. The Maroon Creek Club Master Association's address, for the purposes of this application, is c/o Brooke A. Peterson, Esq., Kaufman & Peterson, P.C., 315 East Hyman Avenue, Suite 305, Aspen, Colorado 81611; telephone: 970-925-8166. Furthermore, we, as attorneys for the Maroon Creek Club Master Association, certify that all of the information contained in the submission is correct. 5. Location ofProperly. The property affected by this request is the Maroon Creek Club Subdivision, located adjacent to Tiehack Road and The Buttermilk Ski Area in the City of Aspen. 6. Explanation of Proposal. The purpose of this application is to clarify what may be done in the land areas between the edge ofthe building envelopes and the lot lines of certain lots in the Maroon Creek Club Subdivision. The Applicant believes that it was never the intent of the Board of County Commissioners when this subdivision was approved to disallow all development outside the building envelopes on the affected lots. Indeed, many of these lots have already been developed with improvements which technically would be prohibited by an interpretation of PUD and City regulations which would disallow all development. This interpretation is also inconsistent with the recorded Protective Covenants for the Maroon Creek Club Subdivision, the design guidelines for this subdivision and the approvals for this subdivision. The requested clarifications do not alter the actual use of the lots in any manner and will indeed make them more aesthetically pleasing. With respect to the criteria set forth in Attachment #5, Review Standards. to the Pre-Application Conference Summary, we believe that the explanation above addresses Criteria #1. We do not believe, for obvious reasons, that Criteria #2 through #8 are applicable to our request since these will be fundamentally no change to the Maroon Creek Club Subdivision as approved and Ms. Julie Ann Woods, Director Mr. James Lindt, Zoning Enforcement Officer June 25, 2001 Page 3 contemplated by the granting of the proposed amendment, and none of the actual land areas of the existing parking, open space, streets, or easements will be affected. Clearly, this is not a commercial proj ect nor will the residential density be affected. With respect to Criteria # 9, we do not believe that the proposed amendment will have any effect other than confirming what all of the landowners and the Maroon Creek Club Master Association have thought since the inception ofthe Maroon Creek Club Subdivision, which is that the landowners would be allowed to do landscaping and permitted improvements in the area between the building envelopes and the lot line, subject to the prior approval of the Maroon Creek Club Master Association. 7. Prior Approvals. Enclosed herewith are copies of the final County Resolution granting approval for the Maroon Creek Club Subdivision, the Subdivision Improvements Agreement, and Ordinance No. 40 annexing this property into the City of Aspen. 8. Vicinity Map. Enclosed is a copy of the vicinity map o f the Maroon Creek Club Subdivision. 9. Planned Unit Development Map. Enclosed is a copy of the first page of the Plat for the Maroon Creek Club Subdivision. 10. Recorded Documents. Other than the enclosed documents, we do not believe any other recorded documents will be affected by this application. We respectfully request therefore that the Insubstantial PUD Amendment as set forth herein be approved administratively by you as soon as possible. Should you need any further information, please do not hesitate to contact me. Thank you for your time and attention to this matter.

I, James:, I Please *cept this letter as a modification to the application submitted by Brooke Peterson on behalf of the Master Association. Since both parties would like to get the language agreed upon before your vacation and Brooke is not available right now, I will confirm our conversation as you requested. e ' 1 Based on the conversation you and I had this morning about the appropriate lots to be included in the amendment, the proposed amendment should include all lots which do not clearly show distinct building and dev#lopment envelopes on the plat map. By my count, this would include the following lots: tots 13,14,15,19 - 40 inclusive, and 46 - 48 inclusive. Lots 15 *rough 24 inclusive would be subject to the two types of"rear yard' restrictions set forth in your amendment in order to preserve the wildlife corridor. We would also appreciate your including the other clarifications that you and I discussed so that MCC can hav* a final version of the amendment before the end of the day. Upon your return, we can get Julie Ann WoÂ¢ds and Gary Albert to execute the amendment. Thank ylu for your continuing assistance - please call if the above does not agree with your list.

Page 16 Mountain Drivewav Best M_. agement Practices Manual April 1999 Silt Fence Type: Temporary Description Silt fences are temporary barriers constructed of woven, synthetic material attached to posts. The goal of this BMP is to pool water from an croding area, allowing the sediment to settle. Sediment transported off-site can otherwise collect in drainages, waterways, wetlands or adjacent properties. Installation/Design Guidelines 1. Secure filter fabric to the ground by installing wooden posts to a depth of 12 inches and exeavating a trench approximately six inches deep along the line of the post and upslope from the barrier. Bury lower eight inches of filter fabric into this trench and compact the backfill soil. 2. Posts should be spaced a maximum of 10 feet apart. For shallow channel flow applications, the pests should be spaced a maximum of three feet apart and reinforced with wire mesh. The base of the fence should be secured. 3. Silt fences installed across a ditch or swale must have the bottom o f the ends of the fence at a higher elevation than the top center of the fence. 4. Silt fences should be installed along the contour at the base of gentle slopes in areas where upi&~adient disrurbance is occumng. f Silt fences should remain in place until vegetation has been established. Special Considerations in Mountainous Areas 1. Thin, rocky soils may preclude the use ofthis BMP in mountainous areas. 2. In areas prone to rockfall, install a wire mesh fence uphill 10 feet o capture rocks that may damage the fence. 3. When equipment is working near sensitive areas or when substantial movement of fill is taking place, it may be necessary to reinforce the silt fence with wire mesh. Maintenance 1. Remove excess sediment periodically, at a minimum when the sediment reaches one-fourth of the silt fence height. 2. Repair or replace damaged fence, and replace broken posts. 3. Check weekly and before and after storms. Silt fence may only perform for a period ofweeks or months. 4. Remove silt fence when area has been successfully revegetated.

Page 29 Mountain Driveway Be~ Wlanagement Practices Manual April 1999 Grass-lined Swales C Type: Permanent Description Grass-lined swales are densely vegetated small drainageways with low-pitched side slopes that collect and slowly convey runoff. Design of their longitudinal slope and cross-section size forces the flow to be slow and shallow, thereby facilitating sedimentation while limiting erosion. Installation/Design Guidelines 1. Roadside swales should be designed to convey concentrated surface nmoff to a receiving channel without damage from erosion. 2. Berms or check dams should be installed within the swale perpendicular to the flow as needed to slow it down and to encourage settling and infiltration. 3. Channel cross-section and lining should be considered based upon volume and velocity of expected flow. Possible cross-section shapes include "V'-shaped (low water), parabolic (high water, low velocity) or trapezoidal (high water, high velocity). 4. Establishing a dense, resistant vegetation is essential. 5. Stabilize the outlet. Special Considerations in Mountainous Areas 1. Grass may be difficult to establish and maintain in arid and cold areas. Riprap can be used to stabilize roadside ditches in place of vegetation, although the cost is much higher. Erosion matting can provide stability until vegetation is established. 2. Grass swales are not appropriate for steep slopes (>2 percent). 3. Avoid sharp changes in direction or grade. Maintenance 1. Mow no closer than six inches, and preferably taller, to increase filtering ability. 2. Wider, fIatter, shallower ditches are easier to maintain. 3. Maintain center line ditch grade to be between one and two feet below the edge ofroadway. 4. Keep the grass in healthy condition at all times, since it is the primary erosion protection and filtration media for the swale. Page 28 Mountain Driveway Besâ€žv,anagement Practices Manual April 1999 Revegetation C Type: Pemanent 3 Description Revegetation is the establishment of vegetative cover on soil left bare by the construction process. This process includes seedbed preparation, temporary revegetation and pennanent revegetation. Revegetation limits erosion and sedimentation on areas adjacent to the driveway by preventing raindrop and sheet flow erosion and prevents weed infestation of exposed earth. Installation/Design Guidelines 1. Use native vegetation recommended in your area. A representative list of native seed mixes in Colorado is provided in Appendix 1. 2. Check weights, seed species and puiities prior to planting the seed. 3. Prior to permanent seeding, prepare soil (e.g., roughen soil surface) and, if required, incorporate topsoil, amendments and fertilizer. Use stock-piled topsoil, if possible. Use fenilizer sparingly. 4. Apply mulch after seeding to 11------**Ari~J---*~-*2-- retain moisture and protect from \4~4Cb<x~2-0 ; .=Â·:0~~ erosion. \2<Â»2<\\ 2 , 9'0- il'll 01- 1 Special Considerations in 0 Mountainous Areas 'TRACKNG' *77)4 MACHINERY UP \ AAO 000â€¢/ 7~45- SIOâ‚¬ ARowurs #t ~ 1.

Consult local experts as needed. 2. Steeper slopes require more attention to revegetate. Mulch should be used on slopes steeper than 3:1 and matting or hydromulch should be used on slopes steeper than 2:1. 3. Native grasses can become established without irrigation in most circumstances. Maintenance 1. Check for growth and re-seed areas where the coverage is not complete. Vegetation is considered established when ground cover is achieved which is sumciently mature to control soil erosion (approximately 80 percent coverage) and can survive severe weather conditions. 2. Watering should be performed as needed during the first year of installation in the absence of rainfall. Page 30 11~i?;121;11:I:ill Mountain Driveway Best Management Practices Manual April 1999 Straw Bales ~ Type: Temporary ~ Description Straw bales can serve as a temporary sediment barrier when anchored and placed across or at the toe of a slope to intercept and detain sediment and decrease flow velocities from small drainage areas. Some local governments discourage use of straw bales because of common failures associated with their use and encourage use of silt fence instead. Installation/Design Guidelines 1. Use only in areas of low-velocity nmoff where sheet and rill erosion potential is low to moderate. 2. Proper installation includes a) excavating a trench the width of the bale and length of the proposed barrier to a minimum depth of six inches; b) placing the bales in the trench; c) staking the bales by driving at least two wood stakes a minimum of six inches into the ground and towards the previously laid bale to force the bails together; and d) backfilling soil against the upgradient side ofthe hay bale. 3. "Chink" between bales with loose straw. 4. Al! bales must be either wire-bound or string-tied. 5. Straw bales should remain in place until vegetation is reestablished. Special Considerations in Mountainous Areas 1. Thin, rocky soils may preclude the use ofwooden stakes during installation. 2. If depth to bedrock is shallow, do not use this method. 3. Improved performance can be achieved by installing a silt fence on the upslor: side and placing it over the balrs. Maintenance 1. Remove excess sediment periodically, at a minimum when sediment reaches half of the straw bale height. 2. Repair orreplace damaged bales andreplace broken posts. 3. "Chink" between bales with loose straw. 4. Check weekly and after storms. Bales may only perform for a period of weeks or months. Check for rills under or around bales.

Page 16 Mountain Driveway Best Management Practices Manual April 1999 Type: Temporary Silt Fence Description Silt fences are temporary barriers constructed of woven, synthetic material attached to posts. The goal of this BMP is to pool water from an eroding area, allowing the sediment to settle. Sediment transported off-site can otherwise collect in drainages, waterways, wetlands or adjacent properties. Installation/Design Guidelines 1. Secure filter fabric to the ground by installing wooden posts to a depth of 12 inches and excavating a trench approximately six inches deep along the line of the post and upslope from the barrier. Bury lower eight inches of filter fabric into this trench and compact the backfill soil. 2. Posts should be spaced a maximum of 10 feet apart. For shallow channel flow applications, the pests should be spaced a maximum of three feet apart and reinforced with wire mesh. The base of the fence should be secured. 3. Silt fences installed across a ditch or swale must have the bottom ofthe ends of the fence at a higher elevation than the top center of the fence. 4. Silt fences should be installed along the contour at the base of gentle slopes in areas where upgradient disturbance is occurring. f Silt fences should remain in place until vegetation has been established. Special Considerations in Mountainous Areas 1. Thin, rocky soils may preclude the use ofthis BMP in mountainous areas. 2. In areas prone to rockfall, install a wire mesh fence uphill 10 feet ,0 capture rocks that may damage the fence. 3. When equipment is working near sensitive areas or when substantial movement of fill is taking place, it may be necessary to reinforce the silt fence with wire mesh. Maintenance 1. Remove excess sediment periodically, at a minimum when the sediment reaches one-fourth of the silt fence height 2. Repair or replace damaged fence, and replace broken posts. 3. Check weekly and before and after storms. Silt fence may only perform for a period of weeks or months. 4. Remove silt fence when area has been successfully revegetated.

Page 29 14 Mountain Driveway Best Management Practices Manual April 1999 Grass-lined Swales I Type: Permanent Description Grass-lined swales are densely vegetated small drainageways with low-pitched side slopes that collect and slowly convey runoff. Design of their longitudinal slope and cross-section size forces the flow to be slow and shallow, thereby facilitating sedimentation while limiting erosion. Installation/Design Guidelines 1. Roadside swales should be designed to convey concentrated surface runoff to a receiving channel without damage from erosion. 2. Berms or check dams should be installed within the swale perpendicular to the flow as needed to slow it down and to encourage settling and infiltration. 3. Channel cross-section and lining should be considered based upon volume and velocity of expected flow. Possible cross-section shapes include 'V'-shaped (low water), parabolic (high water, low velocity) or trapezoidal (high water, high velocity). 4. Establishing a dense, resistant vegetation is essential. 5. Stabilize the outlet. Special Considerations in Mountainous Areas 1. Grass may be difficult to establish and maintain in arid and cold areas. Riprap can be used to stabilize roadside ditches in place of vegetation, although the cost is much higher. Erosion matting can provide stability until vegetation is established. 2. Grass swales are not appropriate for steep slopes (>2 percent). 3. Avoid sharp changes in direction or grade. Maintenance 1. Mow no closer than six inches, and preferably taller, to increase filtering ability. 2. Wider, flatter, shallower ditches are easier to maintain. 3. Maintain center line ditch grade to be between one and two feet below the edge ofroadway. 4. Keep the grass in healthy condition at all times, since it is the pdmary erosion protection and filtration media for the swale. Page 28 Mountain Driveway Best Management Practices Manual April 1999 Revegetation Type: Permanent Description Revegetation is the establishment of vegetative cover on soil left bare by the construction process. This process includes seedbed preparation, temporary revegetation and pennanent revegetation. Revegetation limits erosion and sedimentation on areas adjacent to the driveway by preventing raindrop and sheet flow erosion and prevents weed infestation of exposed earth. Installation/Design Guidelines 1. Use native vegetation recommended in your area. A representative list of native seed mixes in Colorado is provided in Appendix 1. 2. Check weights, seed species and purities prior to planting the seed. 3. Prior to permanent seeding, prepare soil (e.g., roughen soil surface) and, if required, incorporate topsoil, amendments and fertilizer. Use stock-piled topsoil, if possible. Use fertilizer sparingly. <*84983$~ 4.

Consult local experts as needed. 2. Steeper slopes require more attention to revegetate. Mulch should be used on slopes steeper than 3:1 and matting or hydromulch should be used on slopes steeper than 2: 1. 3. Native grasses can become established without irrigation in most circumstances. Maintenance 1. Check for growth and re-seed areas where the coverage is not complete. Vegetation is considered established when ground cover is achieved which is sufficiently mature to control soil erosion (approximately 80 percent coverage) and can survive severe weather conditions. 2. Watering should be performed as needed during the first year of installation in the absence of rainfall. Page 30 %PtÂ¢,141'11'11 1 Mountain Driveway Best Management Practices Manual April 1999 Straw Bales Type: Temporary Description Straw bales can serve as a temporary sediment barrier when anchored and placed across or at the toe of a slope to intercept and detain sediment and decrease flow velocities from small drainage areas. Some local governments discourage use of straw bales because of common failures associated with their use and encourage use of silt fence instead. Installation/Design Guidelines 1. Use only in areas of low-velocity nmoff where sheet and rill erosion potential is low to moderate. 2. Proper installation includes a) excavating a trench the width of the bale and length of the proposed barrier to a minimum depth of six inches; b) placing the bales in the trench; c) staking the bales by driving at least two wood stakes a minimum of six inches into the ground and towards the previously laid bale to force the bails together; and d) backfilling soil against the upgradient side ofthe hay bale. 3. "Chink" between bales with loose straw. 4. All bales must be either wire-bound or string-tied. 5. Straw bales-should remain in place until vegetation is reestablished. Special Considerations in Mountainous Areas 1. Thin, rocky soils may preclude the use ofwooden stakes during installation. 2. If depth to bedrock is shallow, do not use this method. 3. Improved performance can be achieved by installing a silt fence on the upslop: side and placing it over the balrs. Maintenance 1. Remove excess sediment periodically, at a minimum when sediment reaches half of the straw bale height. 2. Repair or replace damaged bales and replace broken posts. 3. "Chink" between bales with loose straw. 4. Check weekly and after storms. Bales may only perform for a period of weeks or months. Check for rills under or around bales. Page 15 . 0 0 .

INTRODUCTION Ducote Jax Holdings, LLC, the owner of Lot 24, Maroon Creek Club Subdivision, requests , approval of an insubstantial PUD Amendment to permit the construction of a new single family residence for Wayne and Diane Ducote. The proposed amendment will change the configuration ofthe building envelope to allow the construction of a retaining wall on the downhill side ofthe residence. A retaining wail is required at the proposed location because the platted building ,4 envelope is located on an area ofunconsolidated fill material. The new building envelope will remain the same size as the original building envelope. The proposed reconfiguration will result in a shift of 723 square feet from the northeast and the southwest corners of the envelope to the northwest side of the envelope. The Ducotes have been involved in the planning and design of their new home for approximately the past year. The pre-application conference was conducted with James Lindt on June 29, 2001. Since that conference, the City reviewed and approved amendments to the existing building envelopes in the subdivision as insubstantial PUD Amendments (approved 10-19-01). Unfortunately, the Ducotes were not aware of that review process or the conditions that resulted from it. Condition number one, in particular, provides that " 1. No development (including any landscaping) shall be allowed beyond the rear perimeter ofthe existing approved building envelopes oflots 21 through 24 (see Attachment "D" for areas to remain undisturbed). The Ducotes believe that this condition should not apply to their lot because the development of the home and retaining wall as proposed will not affect the natural drainage system or any existing wildlife corridor. This condition appears to have been required to protect the natural drainage system and to preserve an "important wildlife corridor" as identified by the City Natural Resources and Construction Manager, Steve Ellsperman. The protection of the natural drainage system has also been an important concern of the Ducotes and the Maroon Creek Club Master 1 Association. In consideration ofthese concerns, the project has been designed to carry drainage around the home and to return it to the natural system immediately below the home and retaining wall. The building envelope is located on a previously disturbed site , that contains an unknown amount of fill dirt of indeterminate origin. Because ofthese existing soil conditions, the proposed location ofthe retaining wall is necessary to stabilize the existing slope and protect the future residence from potential slope failure. A drainage report from Resource Engineering and a soil report from HP Geotech are attached for reference. The proposed development should not affect any important wildlife corridors because the area immediately adjacent to this lot is blocked by large retaining walls for Pfister Drive. This project has been reviewed and approved by the Maroon Creek Master Association a letter from them is included with this application. This application also includes letters of support from the two adjacent lot owners. The Applicant has attempted to provide all of the material requested by the Staff. If additional information is required, the Applicant will make every attempt to provide the requested information. 2 2. INSUBSTANTIAL PUD AMENDMENT, SECTION 26.445.100 The Ducotes request approval of an Insubstantial PUD Amendment to reconfigure the building envelope for Lot 24, Maroon Creek Club Subdivision pursuant to Section 26.445.100 ofthe City Land Use Code. This section of the application will outline the Insubstantial PUD Amendment criteria and the Applicant's response to those criteria: Code: 66 A. PUD Insubstantial Amendments. An insubstantial amendment to an approved development order for a final development plan may be authorized by the Community Development Director. The following shall not be considered an insubstantial amendment: 1 1. A change in the use or character of the development." APPLICANT'S RESPONSE: The proposed residence does not change the use or the character ofthe development. Code: "2. An increase by greater than three (3) percent in the overall coverage of structures on the land." APPLICANT'S RESPONSE: The new building envelope will remain the same size as the originally approved envelope. The construction of a residence on this site will require a retaining wall, the overall coverage of structures on the land will not increase Code: "3. Any amendment that substantially increases trip generation rates of the proposed development, or the demand for public facilities." APPLICANT'S RESPONSE: The proposed building envelope amendment will not affect trip generation rates or the demand for public facilities. 3 Code: "4. A reduction of greater than three (3) percent of the approved open space." APPLICANT'S RESPONSE: The proposed development will not reduce the amount of open space. Code: "5. A reduction by greater than one (1) percent of the off street parking and loading space." APPLICANT' S RESPONSE: The project will not reduce parking or loading space. Code: "6. A reduction in required pavement widths or rights-of-way for streets and easements." APPLICANT' S RESPONSE: The project will not reduce pavement or rights-of-way widths. Code: "7. An increase of greater than two (2) percent in the approved gross leasable floor area of commercial buildings." APPLICANT'S RESPONSE: The condition is not applicable to tile proposed residential development. Code: "8. An increase by greater than one (1) percent in the approved residential density of the development." APPLICANT'S RESPONSE: The proposed project will not increase the residential density of the development Code: "9. Any change which is inconsistent with a condition or representation of the project's original approval or which requires granting a variation from the project's approved use=or dimensional requirements. APPLICANT'S RESPONSE: The Ducotes believe that their proposed home design is consistent with the original project approval. There are no variances from the projects approved use or dimensional requirements. 4 V. ATTACHMENTS 5 ATTACHMENT 1 PRE-APPUCATION SUMMARy 6 2 U L V L.

At the February 21, 2002 meeting of SARC, a request was made to SARC to grant Schematic [preliminary] Approval for lhe plans and to support the appl:cant s proposed request to the Cityof Aspen f for an insubstantial plat amendment lo allow for re-configuration of the established building envelope. As it was presented to SARA Mr. and Mrs. Ducote propose to modify the building envelope to allow for 1) construction of a retaining wall and 2) removal / replacement of an area of deep fill outside of the envelopeinordertoaddress existing drainageproblemsand prevent furthererosion of theembankment. Since thege improvements exceec] 30" n height above existing grade, the plat amendment would apparently be required to accomplish them. SARC reviewed both the house design and the topographic and drainage issues involved with the request and asked you to provide the following additional information prior to any approvals: 1. The consent of Mr. David Chamberlain as the owner of the adjacent Lot 25. The consent of the ownerof theonly other contiguouslot, Lot 23, had alreadybeen provided to the Committee with the application. 2. Ari engineered drainage plan for the proposed modifications to existing drainage patterns to ensure that any new construction would not adversely affect either neighboring lots downhill of Lot 24 or the golf course below.

We also received from you a copy of e letler from the geotechnical engineer establishing that there is a great amount of unconsolidated fill in the vicinity of the building envelope, and that a retaining wall and replacement of the fil will be required to stabilize this area. Based on the documented need to address drainage and slope instability cn the property, the Site and Architecture Review Committee of the Maroon Creek Club Master Association supports the Ducotes' request to the City of Aspen for an insubstantial amendment to the plat for Lot 24 in order to reconfigure - the building envelope in the manner you have proposed, as long as the square footage of the amended envelope is the same as the original. SARC requests that you pursue your application with the Cityand has continued any further design reviews until such time as the City approves the modified building envelope. If the City staff has any questions about the Association's position of support on the application, please have them contact me at any time.

I have enclosed a preliminary site plan which delineates the location of the residence, associated flat work, driveway and landscape screening, We have prograrnmed large evergmens between our two properties whlch should provide adequate sgrecning. Not only will the trees screen our driveways, they will also provide privacy for your property from our side terrace. We have also engaged a drainage engineer to propose a permanent solution to seasonal water nmoff from the street Richard Wax and I have agreed to split this remedial cost and the plan should eliminate existing drainage problems on your property. I believe we both want the same level of separation between our properties and ifthe landscaping shown on the plan proves to be inadequate, we will add more trees until wc achieve the desired effect 1 have also enclosed a copy of a letter prepared by my architect, Jaok Miller,to the M=on Creek Homeowners Association indicating your approval of our pIan.

The existing vegetation includes aspen and evergreen trees with gamble oak and service berry brush with various grasses. The soil is primarily Morval loam. However, fill material was placed on a portion the site during the construction of roads and infrastructure and rough grading of the site. There are two natural drainage swales across the property, both of which receive point source discharges of storm water from culverts under Pfister Driver. The western swale is away from the building envelope and is undisturbed by the proposed project. The central swale runs through building envelope and the storm water flow must be rerouted around the proposed house. The source of water for this swale is from a 24 inch culvert under Pfister Driver which conveys storm water collected from a relatively small offsite basin. It is proposed to route the drainage from the 24 inch culvert around the house and back into the swale at the north property line. RUNOFF O ff-S ite The off-site drainage basin tributary to the 24 inch CMP under Pfister Drive includes approximately 10.2 acres of forested and grassed hillsite, portions of two developed lots, and approximately 4,000 square feet of roadway. The rational method was used in calculating the peak flows for the two year and 100 year storm events. The two year flow is calculated at 0.84 cfs. The 100 year flow is calculated at 12.4 cfs. The assumptions and calculations are presented in the appendix. im lot 24 drainage.890.wpd Consulting Engineers and Hydrologists 909 Colorado Avenue I Glenwood Springs, CO 81601 â€¢ [970]945-6777 1 Fax [970]945-11 37 Mr. Jack Miller March 7,2002 Page 2 Site The project site includes 0.604 acres. The two year peak runoff rate is calculated at 0.22 cfs. The peak 100 runoff rate is calculated at 1.6 cfs. The assumptions and analysis are presented in the appendix. Design Flow Since the 24 inch culvert under Pfister Drive has the capacity to convey the 100 year flow from the off-site basin, the pipeline through the property is likewise sized to convey the 100 year flow for the off-site basin plus the on-site basin. This is a conservative assumption since the peak flows do not coincide and approximately half of the site drainage will be conveyed through the pipeline. The design flow is 14 cfs for the combine J off-site and site drainage. DRAINAGE PLAN The overall drainage master plan forthe Maroon Creek Subdivision provides for routing the off-site and subdivision area drainage to Maroon Creek or through the golf course ponds consistent with the historic drainage patterns. The drainage from Lot 24 flows down the swales, into the large swale along the golf course (which includes the Willow Creek Ditch channel), into the golf course pond system, and eventually to the Roaring Fork River. The golf course ponds were designed to provide detention storage for up to the 100 year storm event. The drainage plan outlined below is consistent with the overall drainage master plan for the subdivision. The off-site drainage will be picked up in a 24 inch pipeline and routed around the house and discharged into the existing drainage swale consistent with the historic drainage pattern. The design of the pipeline will include water tight joints, manholes at the bends, and concrete inlet and outlet structures to anchor the pipe. The outlet structure will be designed to dissipate energy. The existing eroded gully will be stabilized by construction of a retaining wall and fill to reclaim the upper area, and rock riprap/vegetation to stabilize the gully below the outlet. A portion of the steep eroded portion of the gully is on the adjacent Lot 23 property. It is anticipated that the Lot 23 owner will cooperate in allowing stabilization of the eroded gully below the Lot 24 property line. The proposed location of the pipeline structure is shown on the attached Figure 1. The site drainage will generally follow the historic drainage pattern on the site. The general concept is to direct drainage away from the house structure. Area drains are proposed in the front of the house and in the rear of the house where continuous slopes or swales are interrupted by walk ways and retaining walls. These area drains will be connected into the proposed 24 inch drainage pipeline. The proposed site drainage concept is shown on the attached Figure 1. jm lot 24 drainage.890.wpd ..... .....

EROSION AND SEDIMENT CONTROL Construction on the site will require implementation of erosion and sediment control measures. These include silt fence around the downstream perimeter of disturbed areas and installation of hay bales or erosion control logs in all drainage swales. The proposed location for erosion and sediment control measures are shown on the attached Figure 1. Details for construction of these items is also attached to the study. The erosion and sediment control measures must remain in place until all disturbed area are revegetated or stabilized. CERTIFICATION This report was prepared by Michael J. Erion, a Colorado Registered Professional Civil Engineer familiar with urban and rural drainage and flood control design and construction practices. The proposed drainage plan is consistent with the overall master drainage plan of the Maroon Creek Club Subaivision and will not cause damage to adjacent or downstream properties resulting from erosion, flood or environmental impact during construction and after completion.

The review was conducted to evaluate the feasibility of constructing a retakling wall to elevate and level the site for the residence. The proposed concrete wall will be about 1() feet high and is needed roughly along the north building envelope line to build the residence. Borings 1 and 2, located just to the south of the proposed wall, encountered between 17 to 23 feet of fill material judged to be unsuitable for building support. We assume that the proposed building has been designed based on our preliminary recommendations for spread footings and that no more than 10 feet of compacted structural fill will underlie the footings. Based on our review, the proposed retaining wall appears feasible provided title existing fill is completely removed and the site elevations are re-established as recommended in our previous report. Additional exploratory borings should be drilled to evaluate existing fill depths within the wall area and at other parts of the building for site specific foundation and grading design recommendations. If you have any questions or need further assistance, please call our office. Sincerely, HEPWORTH - PAWLAK GLQ~CHNICAL, INC. Steven L. Pawlak, P.11*8 1 5222 :34,~ %.9/7/.21 1 Rev.
