DEAN STREET Planning and Zoning Presentation 01.07.2025 Agenda 01.07.2025 P & Z Presentation ●Present an alternative redevelopment plan that aligns with city goals. ●Discuss the demolition process and key considerations. ●Highlight the difference between recycling and reusing/repurposing materials. ●Outline energy efficiency measures included in the project. ●Show how this proposal is unique to this specific project. Site Location 01.07.2025 P & Z Presentation Project Location Site Location 01.07.2025 P & Z Presentation Project Location - 825 E. Dean St Existing House -Exterior 01.07.2025 P & Z Presentation -Existing House (1,552 sf) was built circa 1950 -Exterior was not maintained well -Expected interior water damage and mold -Did asbestos & mold testing -Found substantial asbestos and a bit of mold -Conducted asbestos abatement Zoning District -RMF 01.07.2025 P & Z Presentation Demolition Code 01.07.2025 P & Z Presentation 1.Anytime demolition is proposed the applicant shall calculate the area of existing surfaces as follows: a.The surface area of all existing (prior to commencing development) exterior wall assemblies above finished grade. Not counted in the existing exterior surface area calculations shall be all existing fenestration (doors, windows, skylights, etc .) b.The surface area of all existing (prior to commencing development) roof assemblies. 2.The applicant shall calculate the area of existing surfaces that are proposed to be removed and determine the overall percentage that is removed. a.The exterior wall surface area and roof surface area, as described above, to be removed. b.Wall area or roof area being removed to accommodate new or relocated fenestration shall be counted as exterior surface area being removed. 3.If the percentage removed exceeds forty (40) percent, then the development shall be considered Demolition pursuant to Section 26.104.100 c. 5.Replacement of fenestration shall not be calculated as wall area to be removed. New, relocated or expanded fenestration shall be counted as wall area to be removed. 7.Replacement of exterior sheathing when the structural components of that area are to remain, does not count toward the calculation of demolition. 40% Demolition Code -Intent 01.07.2025 P & Z Presentation Our intention is to reduce construction waste sent to landfill & increase energy efficiency of the structure; We are proposing an alternative way to improve upon the intention of the code Sec. 26.580.010. –Purpose (b)Ensuring impactful development activities…furthers the city’s climate goals by improving regulatory responses to natural resource consumption, reduces traffic impacts, encourages a more sustainable diversion of solid waste from the landfill, reduces general construction impacts to the community,and ensures that Aspen continues to be a leader in efficient design practices is a key goal and purpose of this section. Sec. 26.580.080. –Adoption of residential demolition and redevelopment standards for projects that meet the definition of demolition -The Residential Demolition and Redevelopment Standards set forth the design parameters to ensure residential redevelopment improves solid waste diversion, increases the energy efficiency of structures, and reduces negative impacts of construction. Existing House -Interior 01.07.2025 P & Z Presentation -Walls were exposed and showed lumber in great shape -No mold! -They are, however, grossly undersized. 2” x 4” walls and 2” x 8” roof. Does not allow compliance w/ current energy or structural code Current Redevelopment Plan 01.07.2025 P & Z Presentation 60/40 Rule ●Stick with 60/40 ○Additional new lumber required to reinforce all existing areas ○Complies with all current codes ■This process would increase the use of natural resources, create significant waste from cutting new timber, and add more materials to the landfill. ●No exterior sheathing, roofing material, & windows can be reused and must be removed ●A standard exterior wall is constructed with 2x6 wood studs. ○Required in order to bear the weight of the structure, lateral loads, and snow loads. ○6” wall cavity also allows for improved insulation and reduced energy usage for heating/cooling ○A 2x4 wall does not meet today’s codes ●A typical roof depth is 12-14” ○Existing 8” depth has same problems as above. 60/40 Demo Illustration -What We Can Do 01.07.2025 P & Z Presentation Our Proposal to You 01.07.2025 P & Z Presentation ●Propose a thoughtful solution to a problem that aligns with the spirit of the code which will minimize waste, enhance sustainability, and reduce environmental impact. ●New plan revolves around disassembly -We aim to take the intent of the city's 40% demolition rule and even further reduce waste and still promote sustainability. ○The City of Aspen wants all recyclable materials to be diverted from the landfill and recycled, a process that includes transporting them to the facility, sorting them by hand, and storing until another use is found. However, we are proposing to reuse and repurpose 100% of recyclable lumber directly on site. Diverting all usable material from both the landfill and recycling facilities. Demo Proposal -Illustrated 01.07.2025 P & Z Presentation Code allows for demo of all exterior sheathing & windows Code allows for removal of all interior framing This is the framing that is left to use Just in a different form.Code allows 40% of any exterior framing to be demo What we want to do is keep all existing interior framing… & all exterior framing...This is the existing house on the property. Code allows for removal of all interior decking all interior decking... Existing Framing Reuse 01.07.2025 P & Z Presentation Energy Efficiency & Sustainability 01.07.2025 P & Z Presentation If allowed, new construction will be ●More energy efficient ○The exterior walls will be constructed with 2" x 6" framing, allowing for improved insulation and R-value to meet current energy codes. This design meets structural requirements without the need add on to existing lumber, reducing waste and avoiding outdated standards. ●More efficient structurally ○No need to tie into existing structure, reusing 100% of all good lumber (802 pieces, ~6,000 linear feet) ●More Eco-friendly ○Not moving the house off & back to site (reducing need for trucking, fuel emissions, traffic impacts) ○Less new materials necessary (less strain on environmental resources) Who Benefits? ●The Community ○Reduce-Reuse-Recycle-Repurpose, general wellbeing, social responsibility ●City of Aspen ○A Leader in sustainability programs, Recycling and Green initiatives ●Landfill & Ecosystem ○Less strain from solid waste ●Client ○Seeks an energy-efficient design for their full-time home. This solution results in a fully reused, highly efficient building. ●Designers & Architects ○Always looking for ways to be more green and sustainable, solutions like this help us to be good environmental stewards THANK YOU!
