Declaration of Conflicts of Interest:None PUBLIC HEARING: Resolution #1, Series of 2024 - 16 Ajax Avenue - Request for Setback Variance. Applicant Presentation –Chris Bendon – Bendon Adams Mr. Bendon introduced Brittney Shami and Thomas Means as the owners of the property. He then noted the property was located in the Smuggler Run neighborhood and further detailed the location with an overhead photo. He went over the history of the Smuggler Park subdivision and again noted this property was in the smaller Smuggler Run portion that encompassed 17 category 4 units. He said that when the two subdivisions were originally created, they had five-foot setbacks on all sides. In 1990 the City changed the setbacks in the Smuggler Park subdivision to a zero foot on one side and a ten foot on the other side, which was how all the lots were actually situated. Mr. Bendon was not sure why the Smuggler Run subdivision was not part of that decision. Mr. Bendon showed the existing conditions of the lots on the street and noted that they all had units set at zero feet on one side and ten feet on the other. He highlighted the existing location of the unit at 16 Ajax Ave. that was set at 6 inches off the property line on one side. He also noted that there had been one other redevelopment in Smuggler Run with the same setbacks issues and that they had applied for and were approved the same variance that was being requested today. 3 REGULAR MEETING ASPEN BOARD OF ADJUSTMENT JANUARY 11TH, 2024 Mr. Bendon noted that the plan is for a prefab house to replace the existing trailer and it would be set in the same location. He then went over the review criteria for this type of approval and felt that this project and request were consistent with them. Ms. Shami thanked the board for their time to review this and then went over her and Mr. Means’ history with the property and how they landed on the prefab option to replace the existing unit. Mr. Head asked if the public noticing had been provided. Ms. Johnson noted that it had been provided in accordance with the Code. Mr. Head also noted that he was on the APCHA board when Ms. Shami acquired the property, and he attested to the poor conditions of the existing structure on the lot. Staff Presentation –Sophie Varga – Planner I Ms. Varga began by going over some details of the property, its history and the setback variance request, which would reduce the required five-foot side yard setback to six inches on the one side. She showed a site plan that highlighted these dimensions. She then went over the review criteria and noted that staff’s review findings are in exhibit B of the packet. She detailed these findings and said that staff recommends that the BOA approve the variance request with the conditions listed in the resolution. PUBLIC COMMENTS: Mr. Barry Bromka introduced himself as the HOA president of Smuggler Run and that he lived across the street from this property. He noted that he had spoken to all the owners on the street, especially the two neighboring properties and no one had any issues with this variance. BOARD DISCUSSION: The board members did not have any questions and were ok with staff’s request. Mr. Bendon noted that they had reviewed the conditions in the draft resolution and were ok with them. MOTION:Mr. Sandler motioned to approve Resolution #1, Series of 2024. Ms. Feddersen seconded. Roll call vote:Mr. Frank, yes; Mr. Head, yes; Ms. Feddersen, yes; Mr. Sandler, yes. 4-0; All in favor, motion passes. ADJOURN:Mr. Sandler motioned to adjourn the meeting. Ms. Feddersen seconded. Roll call vote:Mr. Frank, yes; Mr. Head, yes; Ms. Feddersen, yes; Mr. Sandler, yes. 4-0; All in favor, motion passes. _____________________ Mike Sear, Deputy Clerk 4 628 McSkimming Road – Dimensional Variance Board of Adjustment Page 1 of 7 MEMORANDUM TO: City of Aspen Board of Adjustment FROM: Jeffrey Barnhill, AICP, Senior Planner THRU: Ben Anderson, AICP, Community Development Director RE: 628 McSkimming Road, Dimensional Variance Review Resolution #____, Series of 2025 MEETING DATE: Thursday, March 6th, 2025 APPLICANT: East Aspen Riverhouse, LLC; 1122 Placetas Avenue, Coral Gables, FL 33146 REPRESENTATIVE: Chris Bendon, BendonAdams, 300 S. Spring Street #202, Aspen, CO 81611 LOCATION: 628 McSkimming Road, Legally Described as: Lot 5, Block 3, Aspen Grove Subdivision, According to the plat thereof recorded September 3, 1963 in Plat Book 2A at Page 291 as reception No. 116127, County of Pitkin, State of Colorado. PID#273717201009 CURRENT ZONING AND USE: 628 McSkimming Road is located within the R-15B zone district and is developed with a single-family residence. Lot Size: ~23,741 square feet SUMMARY OF REQUEST: The Applicant requests a front yard dimensional setback variance from the minimum required in the R-15(B) zone district to accommodate retaining walls for the construction of a new single-family residence. STAFF RECOMMENDATION: Staff recommends the BOA make a finding that a hardship does exists on the subject property and approve the variance request for the construction of a new single-family residence. FIGURE 1: SUBJECT PROPERTY LOCATION REQUEST OF THE BOARD OF ADJUSTMENT: The Applicant is requesting the following approval from the Board of Adjustment: 5 628 McSkimming Road– Dimensional Variance Board of Adjustment Page 2 of 7 • Variance (Chapter 26.314) to grant a dimensional variance for this site, reducing the minimum setback requirements in the R-15B zone district (The Board of Adjustment is the final review authority). BACKGROUND AND EXISTING CONDITIONS: 628 McSkimming Road is identified as Lot 5, Block 3, Aspen Grove Subdivision. The property is currently developed with a multi-story single-family residence. The subject property received a demolition allotment pursuant to Land Use Code Section 26.580. Demolition. The applicant proposes demolition of the existing single-family residence and construction of a new single-family residence. The construction of the new single-family residence requires a front yard setback variance to mitigate driveway slope via construction of several retaining walls. Figure 2: Current Conditions 6 628 McSkimming Road– Dimensional Variance Board of Adjustment Page 3 of 7 R-15(B) Zone District: The R-15(B) zone district requires the following minimum setbacks for a ~23,741 square foot lot: • Front Yard Setback: 30’ • Side Yard Setback: 5’ • Rear Yard Setback: Residential Dwellings: 10’, Accessory buildings and all other buildings: 5’ Request: The Applicant requests approval for a dimensional setback variance for this lot to accommodate construction of several retaining walls of varying size ranging from three and a half feet to thirteen feet in height. Specifically, the following variances are requested: 628 McSkimming Road Setback Variances: • Front Yard Setback: 1.5’ (where 30’ is required) for the purpose of constructing retaining walls. Figure 3: Proposed site plan (Orange is the 30’ front setback where retaining walls would be located) 7 628 McSkimming Road– Dimensional Variance Board of Adjustment Page 4 of 7 Figure 4: Proposed retaining walls within front setback highlighted in blue REVIEWS Setback Variance: The criteria for receiving a variance (Exhibit A) are strict. A property owner must demonstrate that reasonable use of the property has been withheld by the City and can only be achieved by the City providing a variance. In situations where all, or pract ically all, reasonable use of a property is made impossible by development regulations, the City is able to grant a variance to avoid a “regulatory taking”. The property owner must demonstrate that their rights, as compared with owners of similar properties, have been deprived. In considering these criteria, the Board of Adjustment must consider unique conditions inherent to the property which are not the result of the Applicant’s actions and are not applicable to other parcels, buildings, or structures. Staff Comments Generally, properties in the R-15B zone district are subject to steep slopes, 628 McSkimming Road is no exception. The zone districts section of the Land Use Code lay out the dimensional limitations of a zone district. While the requested variance from established setback regulations is not generally consistent with the Zone District section of the Land Use Code (26.710.070. Moderate Density Residential R-15B) it does further the purposes, goals, objectives and policies of the 8040 Greenline Review section of the Land Use Code (26.435.030. 8040 Greenline Review). 8040 Greenline Review is not applicable to properties in the R-15B zone district. However, the requested variance would honor the general principles and objectives found in the 8040 Greenline Review section and what is applied to properties that accommodate this steep of slopes in other zone districts. Specifically, siting a development further up the slope on this property allows for a more natural layout with less grading into the hillside below. Additionally, the site design would allow for reduced grading to minimize disturbance to the terrain, vegetation and natural land features. 8 628 McSkimming Road– Dimensional Variance Board of Adjustment Page 5 of 7 The existing development is located in such a way that portions of the garage and a retaining wall encroach into the 30’ R-15B setback. The new development will need to be pushed back to comply with setback requirements. This will raise the grade for the proposed driveway and necessitate the use of large retaining walls in the setback. While these retaining walls are large in size, staff and the Engineering Department have reviewed the design and ingress/egress requirements and find that the retaining walls are suitable for this site. This proposal eliminates the sections of the existing development that encroach in the setback. Figure 5: 30’ setback (orange) with portions of existing development in the setback (blue) to be demolished In this instance, the applicant requests a setback variance for retaining walls to accommodate the driveway within the front-setback area. Generally, structures in the setback are allowed 30” above and below grade simultaneously for up to 60” in total (26.575.020.[e][5]k). The proposed project requires landscape and retaining walls ranging from five to thirteen feet in height. This information was submitted as supplemental material on January 30th, 2025 and will be included in the packet materials. While this is significant retainage for the site, staff believes that for the environmental concerns listed above that it is better to build, in this instance, higher up on the slope of the mountain. It should be noted that the proposed development requires just the retaining walls to encroach into the setbacks. The house and garage will be located within the established R-15B setbacks on site. Site access is a concern on this property. This is also addressed in the 8040 Greenline Review standards requiring adequate ingress and egress for adequate access to fire protection and snow removal equipment. Adequate site access is a reasonable expectation for property owners in the City of Aspen and lack of adequate site access/access for emergency services is a hardship. The applicant has worked with the Fire Department and emergency services for a design that will enable an ambulance to turn around within the property and exit facing forward. Without a variance for the development of the retaining walls, the driveway conditions would be sub-optimal for emergency and fire services in the event of an emergency. Approving the variance allows for safer daily access as well as the ability for construction vehicles and other services to access the site in a more practical manner. 9 628 McSkimming Road– Dimensional Variance Board of Adjustment Page 6 of 7 While reasonable use of the parcel exists today with the existing residence, the existing residence is set to be demolished. Reasonable use of the parcel will be satisfied by the construction of a new single-family residence. The applicant states that the variance requested is the minimum variance needed to make possible the reasonable use of the parcel. The variance is the minimum needed to construct the residence and driveway in a way that does not push the development further down the hillside. Setback variances for only the retaining walls means that the new single-family residence will reside and conform with the R-15B setback requirements. The applicant brings the current driveway more into conformance with the code and provides safety and emergency access in a practicable manner. Many properties in R-15B are subject to the presence of steep slopes on their properties, special circumstances are unique to this parcel. Specifically, the driveway slope in addition to the steep slopes of the property presents a compelling argument that this lot has special conditions that are unique to this parcel, similar parcels in the same zone district, and do not result from the actions of the applicant. This and other parcels within the same zone district are subject to the same conditions that may not be applicable to other parcels in the City. A reasonable expectation for a property owner in the City of Aspen is that they will have adequate site access and access for emergency services should the need arise. Staff finds that the variance request is reasonable and denying the variance request would cause the applicant unnecessary hardship. This proposal sees the residence within allowable setbacks while allowing for retainage and site walls to allow for safe ingress/egress to the parcel. The closest point from the retaining walls to the property line will be about 1.5’ with much of the retaining walls being further from the property line. Staff finds that the variance request is reasonable and denying the variance request would cause the applicant unnecessary hardship. Referral Agencies Staff referred this request to the Engineering Department for a cursory review of the proposed development. Engineering comments state that: 1. The second driveway/access point must be eliminated 2. Curb cuts should be a maximum of 18 ft. wide when serving a two-car garage. A variance be required if this cannot be achieved. 3. The eventual utility easement abandonment will require a letter from all utility providers authorizing abandonment of the easement. The Engineering Department will work with the applicant team on recommendations and other requirements at building permit submittal. Additionally, the Engineering Department finds that the pre- development topography is an acceptable estimation of historic grade on the site. The pre-development topography is handled administratively so is not a part of this variance. Staff also referred the application to the City Parks Department. Parks had no comments on the proposal. RECOMMENDATION: Staff finds that this application reflects a hardship and warrants the grant of a variance. Staff recommends that the BOA make a finding that a hardship does exist on the property and pass a motion to approve the request. ALTERNATIVE: The BOA may want to make a finding that a hardship does not exist on the property and pass a motion to deny the approval. Should the BOA find a hardship does not exist on the property, a potential motion should reflect property-specific findings. 10 628 McSkimming Road– Dimensional Variance Board of Adjustment Page 7 of 7 PROPOSED MOTION (All motions are proposed in the affirmative): 1) “I move to approve BOA Resolution #_____, Series 2025 and find that a hardship exists on the property.” (This reflects Staff’s recommendation) Or, in the alternative: 2) “I move to approve the denial of BOA Resolution #_____, Series 2025.” ATTACHMENTS: Draft BOA Resolution #_____, Series 2025 Exhibit A – Proposed Site Plan and Renderings Exhibit B – Variance Review Criteria, Staff Findings Exhibit C – Application Exhibit D – Supplemental Application Materials 11 628 McSkimming Road BOA Resolution #__, Series 2025 Page 1 of 6 RESOLUTION #___ (SERIES OF 2025) A RESOLUTION OF THE CITY OF ASPEN BOARD OF ADJUSTMENT APPROVING DIMENSIONAL VARIANCES FOR THE PROPERTY COMMONLY KNOWN AS 628 MCSKIMMING ROAD, LEGALLY DESCRIBED AS: LOT 5, BLOCK 3, ASPEN GROVE SUBDIVISION, ACCORDING TO THE PLAT THEREOF RECORDED SEPTEMBER 3, 1963 IN PLAT BOOK 2A AT PAGE 291 AS RECEPTION NO. 116127, COUNTY OF PITKIN, STATE OF COLORADO.

In order to authorize a variance from the dimensional requirements of Title 26, the appropriate decision-making body shall make a finding that the following three (3) circumstances exist: 1. The grant of variance will be generally consistent with the purposes, goals, objectives and policies of this Title and the Municipal Code; and Staff Findings: 628 McSkimming Road currently contains a single-family residence with a gravel driveway. The purpose statement of the Land Use Code, and the general goal of dimensional requirements, are to establish and enforce clear and consistent regulations to regulate the impacts of development on the neighbors, environment, and City. The dimensional requirements are consistently applied to development in town, unless circumstances exist that prevent an applicant from complying, or literal interpretation of the code would cause hardship. Generally, properties in the R-15B zone district are subject to steep slopes, 628 McSkimming Road is no exception. The zone districts section of the Land Use Code lay out the dimensional limitations of a zone district. While the requested variance from established setback regulations is not generally consistent with the Zone District section of the Land Use Code (26.710.070. Moderate Density Residential R-15B) it does further the purposes, goals, objectives and policies of the 8040 Greenline Review section of the Land Use Code (26.435.030. 8040 Greenline Review). 8040 Greenline Review is not applicable to properties in the R-15B zone district. However, the requested variance would honor the general principles and objectives found in the 8040 Greenline Review section and what is applied to properties that accommodate this steep of slopes in other zone districts. Specifically, siting a development further down the slope on a property allows for a more natural layout with less grading into the hillside. Additionally, the site design would allow for reduced grading to minimize disturbance to the terrain, vegetation and natural land features. The existing development is located in such a way that portions of the garage and a retaining wall encroach into the 30’ R-15B setback. The new development will need to be pushed back to comply with setback requirements. This will raise the grade for the proposed driveway and necessitate the use of large retaining walls in the setback. While these retaining walls are large in size, staff and the Engineering Department have reviewed the design and ingress/egress requirements and find that the retaining walls are suitable for this site. This proposal eliminates the sections of the existing development that encroach in the setback. 21 Board of Adjustment 628 McSkimming Road Dimensional Variances – Review Criteria Page 2 of 3 In this instance, the applicant requests a setback variance for retaining walls to accommodate the driveway within the front-setback area. Generally, structures in the setback are allowed 30” above and below grade simultaneously for up to 60” in total (26.575.020.[e][5]k). The proposed project requires landscape and retaining walls ranging from five to thirteen feet in height. This information was submitted as supplemental material on January 30th, 2025 and will be included in the packet materials. While this is significant retainage for the site, staff believes that for the environmental concerns listed above that it is better to build, in this instance, higher up on the slope of the mountain. Additionally, site access is a concern. This is also addressed in the 8040 Greenline Review standards requiring adequate ingress and egress for adequate access to fire protection and snow removal equipment. Adequate site access is a reasonable expectation for property owners in the City of Aspen and lack of adequate site access/access for emergency services is a hardship. Without a variance for the development of the retaining walls, the driveway conditions would be sub-optimal for emergency and fire services in the event of an emergency. Approving the variance allows for safer daily access as well as the ability for construction vehicles and other services to access the site in a more practical manner. It should be noted that the proposed development requires just the retaining walls to encroach into the setbacks. The house and garage will be located within the established setbacks on site. The applicant has worked with the Fire Department and emergency services for a design that will enable an ambulance to turn around within the property and exit facing forward. Staff finds this criterion to be met. 2. The grant of variance is the minimum variance that will make possible the reasonable use of the parcel, building or structure; and Staff Findings: While reasonable use of the parcel exists today with the existing residence, the existing residence is set to be demolished. Reasonable use of the parcel will be satisfied by the construction of a new single-family residence. The applicant states that the variance requested is the minimum variance needed to make possible the reasonable use of the parcel. The variance is the minimum needed to construct the residence in a way that does not push the development further down the hillside. Setback variances for only the retaining walls means that the new single-family residence will reside and conform with the R-15B setback requirements. The applicant brings the current driveway more into conformance with the code and provides safety and emergency access in a practicable manner. Staff finds the criteria to be met. 22 Board of Adjustment 628 McSkimming Road Dimensional Variances – Review Criteria Page 3 of 3 3. Literal interpretation and enforcement of the terms and provisions of this Title would deprive the applicant of rights commonly enjoyed by other parcels in the same zone district and would cause the applicant unnecessary hardship, as distinguished from mere inconvenience. In determining whether an applicant's rights would be deprived, the Board shall consider whether either of the following conditions apply: a. There are special conditions and circumstances which are unique to the parcel, building or structure, which are not applicable to other parcels, structures or buildings in the same zone district and which do not result from the actions of the applicant; or Staff Findings: While many properties in R-15B are subject to the presence of steep slopes on their properties, special circumstances are unique to this parcel. Specifically, the driveway slope in addition to the steep slopes of the property presents a compelling argument that this lot has special conditions that are unique to this parcel, similar parcels in the same zone district, and do not result from the actions of the applicant. This and other parcels within the same zone district are subject to the same conditions that may not be applicable to other parcels in the City. A reasonable expectation for a property owner in the City of Aspen is that they will have adequate site access and access for emergency services should the need arise. Staff feels that the variance request is reasonable and denying the variance request would cause the applicant unnecessary hardship. The applicant could request that any part of the house be allowed to be built encroaching on setbacks if they wished. This proposal sees the residence within allowable setbacks while allowing for retainage and site walls to allow for safe ingress/egress to the parcel. Staff finds this criterion to be met. b. Granting the variance will not confer upon the applicant any special privilege denied the terms of this Title and the Municipal Code to other parcels, buildings or structures, in the same zone district. Staff Findings: Staff finds that should the Board of Adjustment find that a hardship exists, property-specific findings should be made so that special privilege is not conveyed with the grant of the setback variances. Staff finds this criterion to be met. 23 300 SO SPRING ST | 202 | ASPEN, CO 81611 970.925.2855 | BENDONADAMS.COM November 22, 2024 Jeffrey Barnhill, AICP City of Aspen 457 Rio Grande Place Aspen, CO 81611 RE: 628 McSkimming – Lot 5, Block 3, Aspen Grove Subdivision Request for Front Yard Setback Variance Request for Pre-Development Grade Determination Mr. Barnhill: Please accept this application requesting a variance from front yard setback requirements applicable to 628 McSkimming Road. The variance request is limited to grading within the setback area; placement of structures will be compliant. This application also proposes a pre-development grade determination. Pre-development mapping is provided by professional land surveyor Michael Lafferty. The property is near the top of the Aspen Grove Subdivision and the topography is very steep. The property is currently developed with a dilapidated single- family home. A demolition allotment has been secured and the property will be redeveloped. The picture to the right shows the existing driveway to the 628 property 24 628 McSkimming Road Page 2 300 SO SPRING ST | 202 | ASPEN, CO 81611 970.925.2855 | BENDONADAMS.COM The existing driveway exceeds the allowed grade change within a setback and does not enable a turn-around. Exiting the property in any type of vehicle necessitates backing into uphill traffic. The picture to the right shows a “review mirror” view backing out of the 628 property. Conformance with the 30-foot front yard setback requirement is achieved for the new house and garage The proposed home and garage will be compliant with the required 30-foot front yard setback. In order to access the home with a driveway and enable ambulance access, grade changes within the front setback will exceed the 30-inch limitation. The driveway has been designed to enable an ambulance and any civilian vehicle to turn around within the property and exit facing forward. This is a far-superior situation for everyday safety. With the new driveway, a fire truck will have enough width and an appropriate slope to pull into the property, station for an event, and back out. The driveway length is well under the threshold for requiring a fire truck turn-around and the site grades are far too limiting to enable such a turnaround. The current situation requires any vehicle, including an ambulance, back out of the property into a three-point turn on McSkimming Road. 25 628 McSkimming Road Page 3 300 SO SPRING ST | 202 | ASPEN, CO 81611 970.925.2855 | BENDONADAMS.COM The proposed driveway allows an ambulance or any civilian vehicle to turn around and exit the property facing forward. The new driveway will have the required width and slope to enable a firetruck to pull in, station for an event, and back-out of the property The map to the right highlights in red and orange the grade changes within the front setback area that require a variance. All measurements have been taken from the pre-development grade map prepared by licensed land surveyor Michael Lafferty. 26 628 McSkimming Road Page 4 300 SO SPRING ST | 202 | ASPEN, CO 81611 970.925.2855 | BENDONADAMS.COM A utility easement and overhead power line courses across the southern portion of the property.

The map the right shows the utility easement area to be vacated The Aspen Grove Subdivision was annexed into the City of Aspen in 1987 and is zoned R-15B. This “B” Zone provides a lower floor area than the R-15 Zone District but does not allow duplexes. In addition, development in the R-15B district is not subject to “slope reduction”, 8040 Greenline Review, or the City’s Residential Design Standards.

Vicinity Map 28 Exhibit 1 Review Criteria page 1 Response to Review Standards: Section 26.314.040.A – In order to authorize a variance from the dimensional requirements of Title 26, the appropriate decision-making body shall make a finding that the following three (3) circumstances exist: 1. The grant of variance will be generally consistent with the purposes, goals, objectives and policies of this Title and the Municipal Code. Response – Title 26 of the Municipal Code (known as the Land Use Code) provides zoning limitations and development standards for properties in the City of Aspen. The purpose of Title 26, stated in 26.104.020 includes the analysis of various development factors “and the legitimate rights and reasonable expectations of property owners.” The property is zoned for single-family development and the owner has a legitimate and reasonable expectation to be able to develop a single-family home with a driveway providing safe vehicular access. A variance to required setback grading limitations to enable the development of driveway serving a new home on this property is consistent with the purpose of the R-15B Zone District. 2. The grant of variance is the minimum variance that will make possible the reasonable use of the parcel, building or structure. Response – The application proposes a home that meets the setback requirements for the R15- A Zone District. The variance request is to accommodate the grading limitations applicable within setback areas – 30-inch maximum departure from the pre-development grade. For the purposes of measuring the grade changes, a pre-development grade analysis has been prepared by Sopris Engineering. The 628 McSkimming property is part of the 1963 Aspen Grove Subdivision – Lot 5. The parcel is very steep and the current home is served by a driveway that cuts into the slope beyond the 30-inch allowance of the current Land Use Code. This existing driveway, to our knowledge, was not required to obtain a setback grading variance. The proposed driveway mimics the prior driveway and has been designed with a slope and width to accommodate an ambulance turning around within the property such that the ambulance can exit the property in a forward-facing position. The proposal is a reasonable outcome and respectful of the neighborhood conditions. It will enable reasonable use of the property. The applicant is intending to redevelop the property with a new home in essentially the same position and orientation as the current home. The applicant has taken special care to design the home within the zoning requirements and to request setbacks which are the minimum necessary to make reasonable use of the property. The home will accommodate the owner’s needs and fulfill the development rights expected in the zone 29 Exhibit 1 Review Criteria page 2 district. The new home will comply with the zoning requirements of the R-15B Zone District and the variance request is limited to the site access conditions. The requested variance to the grading limitation will not allow excessive development or provide a development right exceeding that commonly provided in the R-15B zone. 3. Literal interpretation and enforcement of the terms and provisions of this Title would deprive the applicant of rights commonly enjoyed by other parcels in the same zone district and would cause the applicant unnecessary hardship, as distinguished from mere inconvenience. In determining whether an applicant's rights would be deprived, the Board shall consider whether either of the following conditions apply: a) There are special conditions and circumstances which are unique to the parcel, building or structure, which are not applicable to other parcels, structures or buildings in the same zone district and which do not result from the actions of the applicant. b) Granting the variance will not confer upon the applicant any special privilege denied by the terms of this Title and the Municipal Code to other parcels, buildings or structures, in the same zone district. Response – Literal enforcement of this 30-inch grading limitation would eliminate any vehicular access. Development of the home would be effectively denied due to an inability for construction access – concrete trucks, materials delivery, excavation equipment, etc. – and an inability to access the new home with a vehicle. McSkimming Road does not enable parking and simply excavating an area on the property for a vehicle to park would conflict with the 30-inch grade limitation. Literal enforcement will negate reasonable use of this parcel, would cause the applicant unnecessary hardship, and would deprive the applicant of property rights commonly enjoyed by other owners in the R-15B zone district. Enabling the property to develop, by granting the requested variance, will enable the applicant to enjoy development rights in-line with those of neighboring parcels in the R-15B zone district. 30 CITY OF ASPEN COMMUNITY DEVELOPMENT DEPARTMENT City of Aspen|130 S.

It is Block 3, Lot 5, of the Aspen Grove Subdivision. The applicant has already secured a demolition allotment and now wishes to demolish and redevelop the site. The applicant requests setback variances for the redevelopment of the lot. The applicant suggests that grade challenges along the front yard setback of the property require the granting of a setback variance. Some of the work included in the scope that might require variances include: accessways, new structures, and substantial retaining walls that will need to be constructed. These elements will likely exceed the regulations outlined in 26.575.020.E.5(k) Allowed Projections into Setbacks. The applicant has indicated that they are unsure how much of the improvements will encroach into the setbacks. This request for a dimensional variance shall be considered at a public hearing by the Board of Adjustment pursuant to Section 26.314.040. – Standards applicable to variances. Variances are to be granted when “[t]he literal enforcement of the provisions of this title would result in undue and unnecessary hardship.” To approve a dimensional variance, per Section 26.314.040, the Board of Adjustment must make a finding that: 1.The grant of variance will be generally consistent with the purposes, goals, objectives and policies of this Title and the Municipal Code; and 2.The grant of variance is the minimum variance that will make possible the reasonable use of the parcel, building or structure; and 3.Literal interpretation and enforcement of the terms and provisions of this Title would deprive the applicant of rights commonly enjoyed by other parcels in the same zone district and would cause the applicant unnecessary hardship, as distinguished from mere inconvenience. In determining whether an applicant's rights would be deprived, the Board shall consider whether either of the following conditions apply: a.There are special conditions and circumstances which are unique to the parcel, building or structure, which are not applicable to other parcels, structures or buildings in the same zone district and which do not result from the actions of the applicant; or b.Granting the variance will not confer upon the applicant any special privilege denied by the terms of this Title and the Municipal Code to other parcels, buildings or structures, in the same zone district. The application will be referred to the Engineering Department and Parks Department for review.

It is our understanding that the project is seeking approvals for a complete scrape and replace of an existing multistory single family residence on the subject property. It is also our understanding that the project is requesting variances from the Board of Adjustments from portions of Section 26.575.020 of the City of Aspen Municipal Code relative to maximum cuts within the front yard setback. This letter addresses the proposed utility extensions, conceptual site grading and stormwater mitigation options for the project team which will be further evaluated in support of a future Building Permit Application. Background & Existing Conditions The subject property is located at 628 McSkimming Road in Aspen, CO (Parcel ID#273717201009) and according to Pitkin County Assessor’s webpage the existing residence was constructed in 1964 with an effective year built of 1980. The subject property is Lot 5, Block 3 of the Aspen Grove Subdivision that was annexed into the City as part of the Aspen Grove-Eastwood- Knollwood Annexation Plat in 1987 (Ordinance 028-87). Based on our review of the existing conditions survey and site visit the property consists of an existing single story wood frame house and attached garage with a building footprint at ground elevation of approximately 2,560 sf. Two detached sheds with a totaling approximately 230 sf reside along the northern side of the existing residence. Existing ground cover outside of the impervious roof area includes a gravel driveway/motorcourt along the north and east sides of the residence, as well as a gravel access drive to the rear yard along the western property line. The remainder of the property is densely vegetated primarily with several mature deciduous and coniferous trees, scrub oak and native grasses. The total impervious area has been estimated at 7,175+/- sf which includes the existing residence, sheds and impervious gravel drives. Surface grades and existing drainage patterns generally slope from east to west across the site towards the adjacent Aspen Grove Cemetery bordering the western property line. An existing vegetated hillside slopes aggressively away from McSkimming Road (greater than 30%) west toward the existing driveway, motor court and residence. The steep hillside east of the residence slopes in the area appear to be altered from historic, undeveloped topography suggested the excessive slopes may be manmade to facilitate the existing residence and associated driveway. An existing 10 ft general utility easement (Bk 2A Pg 291) located near the western portion of the subject property, and facilitates existing overhead Holy Cross electric, Lumen telephone and Comcast cable lines. Sopris Engineering has coordinated with the respective utility providers on their requirements to facilitate the removal of the overhead lines and onsite utility pole and to vacate the existing 10-ft easement is that currently overlaps the existing residence as well as the proposed building area. A new general utility easement is proposed along the western property line to facilitate the infrastructure required to underground the respective utilities. Further discussion of the existing easement as it relates to this and future development can be found in the Site Utilities section of this letter. Exhibit 13 64 628 McSkimming Road- Engineering Letter- Board of Adjustments November 15, 2024 Page 2 502 Main Street, Suite A3, Carbondale, CO 81623 970-704-0311 According to Figure 3.1 of the City’s Urban Runoff Management Plan (URMP) the underlying soils likely consist of Type B Soils which have moderate infiltration rates, which is consistent with the recent geotechnical borings that are described in CTL Thompson soils report dated September 26, 2024. A design hydraulic conductivity of 0.0033 to 0.00033 ft/sec (142 to 14 in/hr) is recommended for the underlying silty gravel soils, which is in excess of the minimum 3 in/hr for subsurface infiltration BMPs such as drywells. A copy of this report is provided as attachment to this letter. According to FEMA Flood Insurance Rate Map panel number 08097C0366E with effective date of August 15, 2019, the property falls entirely within the Zone X flood hazard area. FEMA designates Zone X as areas outside the 0.2% (500 year storm) annual chance floodplain. A site inspection and Desktop Mudflow Analysis was performed by Tetra Tech on July 9, 2024 in support of the development application as the subject property falls within the yellow and blue mudflow areas of the Smuggler Mountain Mudflow Zone. Tetra Tech concluded that the mudflow risk to the property is “very low” and further detailed debris flow analysis is therefore not needed. City Staff has reviewed the mudflow analysis and is in agreement that no further analysis is needed in support of a future building permit application. Proposed Development, Stormwater Requirements and Stormwater Mitigation It is our understanding that the project will apply for a future building permit to demolish an existing wood framed multi-story single-family residence to facilitate the construction of a new multistory residence with attached garage and motor court; installation of onsite stormwater infrastructure is required to maintain existing drainage patterns. Utility service upgrades will be required to include water, sewer, gas, telephone to serve the proposed residence. The proposed scopes of work will meet the minimum thresholds for a “Major Drainage” project as defined by the City’s Urban Runoff Management Plan. Based on the location of the subject property the stormwater mitigation requirements will include water quality treatment for all exposed impervious areas, and stormwater detention to attenuate developed conditions runoff rates to less than existing conditions. Water Quality Treatment: Based on the estimated total proposed impervious areas, the resulting required water quality treatment volume is approximately 230 cf. The ultimate methods to address water quality treatment runoff from impervious areas will be further evaluated in support of a future building permit application and may include LID strategies such as permeable pavers, green roofs, reduction of impervious areas and drywells. Onsite detention and attenuation of developed conditions runoff rates are anticipated to be achieved through the implementation of onsite drywell(s). Based on the existing site topography and proposed site development the most viable option for providing the required water quality treatment is the integration of onsite drywells. The geotechnical report dated September 26, 2024 states that a drywell is a suitable surface water disposal system. Dry Wells are a stormwater mitigation BMP that incorporates manhole structures with perforated barrels at the deeper depths. Washed screened rock is installed around the exterior of the perforated sections. When sub-soils are capable of moderate to high infiltration rates, dry wells are considered to be a viable BMP. They dramatically reduce the increased runoff and volume of stormwater generated from surrounding impervious areas and promote infiltration; thereby improving the water quality of stormwater runoff. The required water quality capture volume for a dry well shall be 150% of the design water quality capture volume as outlined within Chapter 8 of the City’s URMP. Per the City’s URMP dry wells shall not be located within 10-ft of any structure or 10-ft from a property line. Potential drywell location(s) are illustrated on the attached conceptual drainage plan and there are no anticipated site constraints prohibitive of installing onsite drywell(s) compliant with Section 8.5.4.2 of the URMP. Access Access to the subject property is from an existing gravel driveway at an acute angle from McSkimming Road which terminates at an existing two-car garage on the east side of the existing residence. McSkimming Road slopes from south to north at 8%- 10% longitudinal grade along the property’s northern and eastern lot frontages. The existing driveway width varies and, in some 65 628 McSkimming Road- Engineering Letter- Board of Adjustments November 15, 2024 Page 3 502 Main Street, Suite A3, Carbondale, CO 81623 970-704-0311 places, less than the 16’ minimum driveway width required by current City of Aspen Engineering and Aspen Fire Protection District’s (AFPD) standards. Existing driveway slopes aggressively from McSkimming road (10%-12%) toward the garage, which is set well below the elevation of McSkimming Road above. A steep treed and densely vegetated hillside resides between existing gravel drive and the edge of McSkimming Road. The vegetated hillside has slopes of approximately 1.5’-2.0’(H) to 1(V) and appears to have been cut from pre-developed grades to facilitate the existing driveway alignment. The site design additionally provides insufficient room for onsite vehicular turnaround requiring vehicles to back onto McSkimming Road with inadequate sight lines to oncoming traffic. The existing driveway configuration and grades are additionally restrictive to emergency service vehicles creating potential life safety concerns. Alternative access points to the proposed redevelopment is limited and the existing curb cut is located at the lowest elevation of McSkimming Road along the lot frontage. The proposed driveway alignment and motor court provides adequate turnaround room for both residential vehicles as well as an emergency services ambulance. The driveway will be widened to 16’ minimum width with 10% maximum longitudinal grade and a motor court with maximum 4% grades – providing safe access and staging accommodations for AFPD District’s fire truck. Uphill soil retention is proposed to bring the driveway in compliance with current minimum width standards while providing 10% maximum longitudinal grades. The applicant is seeking variance from the maximum cut or fill from natural grade in order to facilitate the driveway/motor court design and provide safer ingress/egress to the subject property. Site Utilities Coordination with the various utility providers has taken place to verify layouts, routing, and feasibility of serving the proposed improvements. This section of the letter describes our findings. Extensions of primary electric, telephone and cable infrastructure and reconnection of existing customers are proposed to facilitate the removal of the overhead utility lines and associated utility easement currently bisecting the development area. The offsite utility extensions are anticipated to be permitted through a separate Landscape and Grading permit in advance of the Building Permit for the onsite development. Preliminary utility plans have been included within the attached civil drawings for illustrative support. Additional details and finalized design will be submitted when a Building Permit Application is pursued. Water Service & Fire Flow Analysis The City of Aspen Water Department is the provider of potable water for the subject property. Currently the site is served off the existing 6-inch DIP water main that runs along the east side of McSkimming Road. The existing service size is unknown but is anticipated to be undersized to meet the fire flow requirements of the proposed development. The service is anticipated to be capped and abandoned at the main as the current alignment conflicts with anticipated shoring and site walls needed to facilitate the proposed residence. A new service tap meeting the COA Water Department Standards is anticipated to extend down the proposed driveway to the lower-level mechanical room. Final size of the service line will be coordinated with the Water Department staff based on anticipated building program demands and fire sprinkler suppression requirements. Final fixture counts and resulting consumptive demands will be determined by the Mechanical Engineer and coordinated with City staff in support of a future Building Permit Application. Additional tap connection fees will likely be required for the proposed redevelopment project. Sanitary Sewer According to the Aspen Consolidated Sanitation District (ACSD), the existing residence is not connected to their sanitary collection main, and is therefore likely served by an onsite wastewater treatment system (OWTS). The new residence will be required to provide a new service tap to the existing 8” PVC collection main within McSkimming Road. The depth of the main is higher than the main level finished floor elevation. The entire residence will therefore need to be lifted to a new gravity sewer service connection at the property line. New service tap fees are expected to be required as part of the redevelopment and will be due at the time of Building Permit issuance. 66 628 McSkimming Road- Engineering Letter- Board of Adjustments November 15, 2024 Page 4 502 Main Street, Suite A3, Carbondale, CO 81623 970-704-0311 Shallow Utilities The shallow utilities proposed to serve 628 McSkimming include electric, cable, and natural gas. The information provided within this section includes utility locates obtained during the improvement survey as well as discussions with the individual utility providers. Holy Cross Electric currently serves the subject property via a pole mounted transformer located within an existing general utility easement (Bk 2A Pg 291 659373) near the northwest corner of the subject property. The existing utility pole additionally provides aerial service to 653 and 755 McSkimming via an secondary aerial service utility pole on the east side of McSkimming Road. To remove the utility poles and aerial electric lines, new primary electric lines will need to extend underground down McSkimming Road to existing spare conduits in the right of way below 813 McSkimming Road, installed by Hendrickson Construction under a separate building permit (0133-2021-BRES). A new electric transformer and secondary junction box will be located within a new utility easement along the west side of the subject property, and existing customers will be reconnected and refed to maintain service. The existing 10’ general utility easement will then be vacated with a new varying width easement established along the western property line. This scope of work is proposed in a separate Landscape and Grading permit to be facilitated in advance of a Building Permit associated with the subject property. Secondary electric service to the proposed development at 628 McSkimming will be extended from the new pad mounted transformer in the northwest corner of the subject property and will be finalized in support of a future building permit for the proposed residence. Comcast Cable service is currently provided via an existing aerial pedestal located near the northwest corner of the property. Additionally, Comcast main feeder lines are along the aerial service lines that currently bisects the subject property. To remove the utility poles and aerial feeder lines, new primary cable lines will need to extend underground down McSkimming Road to existing spare conduits in the right of way below 813 McSkimming Road, installed by Hendrickson Construction under a separate building permit (0133-2021-BRES). A new cable pedestal will be located within an existing utility easement along the west side of the subject property, and existing customers will be reconnected and refed to maintain service. This scope of work is proposed in a separate Landscape and Grading permit to be facilitated in advance of a Building Permit associated with the subject property. New cable service will be extended to the proposed residence from the new pedestal along the wester property line, should the development desire cable service. Lumen Telephone service is currently provided via an existing aerial pedestal located near the northwest corner of the property. Additionally, Lumen main feeder lines are along the aerial service lines that currently bisects the subject property. According to Lumen representatives, the aerial line does not currently serve a significant amount of customers, and will be removed from the existing utility poles in early 2025. Primary telephone will now terminate within an existing at grade pedestal (#0141) near the southwest corner of the property. New primary extension down the McSkimming is therefor no longer required and telephone service to the subject property (and surrounding properties) will no longer be provide by Lumen. Black Hills Energy Gas an existing gas service line is provided to the existing residence from a main line on the west side of McSkimming Road. The existing service continues down the existing steep vegetated hillside, beneath the existing gravel driveway to an existing meter near the front door of the existing residence. Black Hills Energy does not have documentation on the existing size and material of the existing gas service. Due to the potential conflict of the existing gas service line with future site walls, a new gas service is anticipated beneath the proposed driveway to serve the new residence. The existing service will be abandoned at the main per Black Hills Energy standards. 67 628 McSkimming Road- Engineering Letter- Board of Adjustments November 15, 2024 Page 5 502 Main Street, Suite A3, Carbondale, CO 81623 970-704-0311 Conclusion Based on our evaluation of the existing site conditions and proposed development the project has a viable option for providing water quality, stormwater detention and utility services available to serve the proposed improvements on the subject property. The design of all onsite stormwater mitigation infrastructure, water quality treatment facilities, and utility service extensions, to include size and location, will be further analyzed as the project design progresses. Final designs being provided with any future building permit application. If you have any questions or need any additional information, please don’t hesitate to contact our office.

The property is located within the City’s mudflow hazard zone (Figure 1). As a part of City regulations (City of Aspen, 2014)) and in accordance with Ordinance No. 19 (Series of 2016), a mudflow analysis is required to demonstrate that the project does not increase mudflow elevations on down-fan properties. Tetra Tech performed a site visit and a desktop analysis to evaluate the mudflow risk. Tetra Tech believes that the mudflow risk to the property is very low and requests that the City waive the requirement to perform site specific mudflow modeling. The following sections detail Tetra Tech’s findings and conclusions. 2.0 SITE VISIT AND DESKTOP ANALYSIS Tetra Tech performed a site inspection and desktop analysis to assess the likelihood of debris flows on the approximately 0.55-acre lot. The site inspection was performed by Dr. Dai Thomas, PE on July 9, 2024 to assess the project site, the uphill drainage characteristics, topography and potential clearwater/debris flow path(s). A digital terrain model (DEM) and contour mapping were developed for the Project and surrounding area based on topographic data obtained from the City of Aspen Geographic Information System (GIS) website1 and the Colorado Hazard Mapping website2. The DEM was used to compute the uphill drainage (subbasin) which has an area of 8 acres (0.0125 mi2) and an average slope of 42-percent (Figure 2 and Figure 3). The drainage above the property has a relatively uniform surface across the hill and does not have a defined flow path or swale that could potentially collect and concentrate flow. No evidence of mining debris, mass wasting or slumping on the uphill drainage was observed. 1 City of Aspen GIS AGOL (arcgis.com) 2 Colorado Hazard Mapping & Risk MAP Portal - CO Hazard Mapping & RiskMAP Portal 95 TETRA TECH 2 Figure 1 Site location map 96 TETRA TECH 3 Figure 2 Contour map and flow lines 97 TETRA TECH 4 Figure 3 Screen capture showing oblique view of the project. Screen capture from the City of Aspen’s GIS AGOL Scene Viewer. 628 McSkimming Road 98 TETRA TECH 5 The Aspen Grove Cemetery is located downhill of the property. The closest building downhill of the Project, is approximately 700 feet. The ground is comprised of silt to small gravel sized material, and no boulder sized material was observed. There is no evidence of previous mudflows either on uphill watershed or on the Project property. There are potential flow paths located on both sides of the Project; these flow paths continue downhill past the Project and do not impact the project (Figure 1). The hillside well vegetated with mature shrub brush, aspens and firs that provide slope stability (Ph oto 1 and Photo 2). The location of Photo 1 and Photo 2 is shown on Figure 4. It was challenging to obtain representative photos of the uphill watershed due to the thick vegetation. 2.1 HYDROLOGY ANALYSIS To our knowledge, there is no existing hydrology or debris flow models of the project area. Tetra Tech performed a hydrology analysis to estimate the flows originating from the uphill watershed for the 100-year rainfall event. Rainfall-runoff modeling was performed using the United States Army Corps of Engineers (USACE) Hydrologic Modeling System (HEC-HMS Version 4.12) computer software (USACE, 2024) to estimate the peak flows for the 100-year rainfall event. HEC-HMS simulates the precipitation-runoff response of the watershed by performing mathematical computations for four hydrologic and hydraulic processes: • Precipitation • Infiltration • Transformation of precipitation excess to subbasin outflow • Hydrograph routing As previously discussed, the watershed was delineated based on the DEM. 2.2 PRECIPITATION Debris flows are typically generated during short duration and intense thunderstorm events. A 2-hour hyetograph was developed to represent a short-duration thunderstorm for the 100-year peak rainfall event based on the Colorado Unit Hydrograph Procedure (CUHP) developed by the Urban Drainage and Flood Control District (UDFCD, 2014). The 2-hour hyetograph is developed based on the 1-hour point rainfall depth, similar to the design storm used by UDFCD, but adjusted for local precipitation frequency (Table 1). The process for developing the 2-hour hyetographs from the one-hour point rainfall depths is described in the Rainfall Chapter of the Aspen Urban Runoff Management Plan (City of Aspen, 2014). The 1-hour, 100-year rainfall value of 1.28 inches was obtained from the NOAA Point Precipitation Frequency Estimates website3. The CUHP adjusted 2- hour 100-year rainfall is 1.48 inches (Table 1, Figure 5). 3 PF Map: Contiguous US (noaa.gov) 99 TETRA TECH 6 Photo 1 View looking uphill (north) at the watershed from 628 McSkimming Road.

Soil mapping and the associated soil properties database was obtained from the Natural Resources Conservation (NRCS) website 4 for the “Aspen-Gypsum Area, Parts of Eagle, Garfield, and Pitkin Counties”. The soil mapping indicates that the upper watershed is mapped as mine loam and lists the Hydrologic Soil Group (HSG) assigned to represent relative infiltration. The HSG’s are A, B, C and D with the A soils having the highest infiltration rates and D soils have the lowest. The entire watershed was assigned to the HSG A group, which are “Soils having 4 https://websoilsurvey.sc.egov.usda.gov Event 1-Hour NOAA Atlas 14 Value 2-Hour Adjusted 100-Year 1.28 1.48 102 TETRA TECH 9 high infiltration rates even when thoroughly wetted, consisting chiefly of deep, well to excessively drained sand and/or gravel. These soils have a high rate of water transmission and would result in a low runoff potential.” A curve number was determined from StreamStats 5 and an analysis of the small watershed located to the east of the property, which has the same soil and vegetation characteristics. StreamStats does not provide a flow path for the Project drainage, and therefore, the neighboring drainage was used. Based on StreamStats, a CN value of 55 was applied to the model. The initial abstraction represents the amount water loss that occurs before runoff, and generally represent losses due to infiltration, depression loss and rainfall interception by vegetation. The initial abstraction is computed as a function of the curve number as shown in Equation 1. IA = 0.2 ((1000/CN) – 10) (1) Where: IA = initial abstraction CN = curve number Based on equation 1, an IA value of 1.64 inches was applied. 2.3 BASIN PARAMETERS AND UNIT HYDROGRAPHS The Clark Unit Hydrograph method was used to transform the excess precipitation into sub-basin hydrograph. The unit hydrograph parameters included the Time of Concentration (Tc) and a Storage Coefficient. The Tc values were computed based on the following equation developed by Sabol (2008) for the Rocky Mountain region: Tc = 2.4 A0.1 L0.25 LCA0.25 S0.2 (2) Where: A= area (mi2) L = longest flowpath length (mi) LCA = centroidal flowpath length (mi) S = longest flowpath slope (ft/mi) The basin parameters were computed in HEC-HMS based on the terrain. The Tc and R coefficients were computed using the “Clark UH parameter.xls” spreadsheet provided by the Colorado State Engineers Office (SEO ). The calculated TC and R values for the R/(Tc+R) ratio of 0.7 is shown in Table 2. Table 2 Summary of basin values for the unit hydrograph method. Sub-basin Area (mi2) Longest Flowpath Length (mi) Longest Flowpath Slope (ft/mi) Centroidal Flowpath Length (mi) Tc (hrs) R (hrs) Sub-1 0.01 0.30 2,010 0.13 0.15 0.35 5 streamstatsags.cr.usgs.gov/streamstats/ 103 TETRA TECH 10 2.3.1 Model Results The hydrology model was run for the 100-year rainfall event and the predicted peak flow was 0.6 cfs. A sensitivity analysis was performed to evaluate the effect of increasing the CN on peak flow. A conservative CN of 75 and IA value of 0.67 inches was applied to the model, which resulted in a peak flow of 1.3 cfs. Based on the hydrology analysis, it is concluded that the uphill drainage produces very little runoff from the uphill which is insufficient to generate and transport mudflow. The analysis assumes that the flow paths on either side of the property do generate a debris flow and avulse on to the project property which is very unlikely based on the hillside topography. 3.0 RECOMMENDATION Based on the site investigation and desktop analysis: (1) there is no evidence of historic debris flows, (2) there is no defined flow path or sediment build up, and (3) the runoff from the uphill drainage at the 100-year event is low. For these reasons, it is Tetra Tech’s opinion that the mudflow risk is very low and there does not need to be a detailed debris flow analysis performed for this property. For properties on a hillslope, it is prudent to develop appropriate site grading to convey flows away from buildings, and to place windows and doors on downhill sides of the buildings to provide an extra layer of protection against potential flooding and property damage. Tetra Tech did not evaluate the potential for mudflow after a wildfire in the basin or other potential hazards such as rock fall or slope instability. 104 TETRA TECH 11 4.0 REFERENCES City of Aspen.

The variance request included reference to planned grading and slope retention for the driveway exceeding 30 inches within the front yard – between the proposed home and the road to the north. Attached to this letter as Exhibit 12.1 are cross sections showing existing and proposed conditions along the proposed driveway. The diagram shows top-of-wall (TOW) and bottom-of-wall (BOW) elevations in their proposed final form. This diagram (if the variance request is approved) can be used to verify compliance during building permit review and during final inspections. We look forward to your review and will make ourselves available for any questions or concerns you have. We can also arrange a site visit at your request.
