1 Infill Guide Infill Guide- Commission Infill design review is a collaborative process used to examine projects in designated historic districts or on Denver landmark properties for architectural design and compatibility with the nearby historic built environment. Applications submitted for infill design review must be accompanied with specific information which adeuately describes and studies the proposal and its relationship to its historic surroundings. To comply with the reuired submittal standards of Denver, submitted documentation shall clearly illustrate the existing conditions as well as any proposed features. To facilitate the mission of the Denver Commission (LPC) to preserve and protect the integrity of Denver s historical and architectural structures, the LPC has developed the Design Guidelines for Denver Landmark Structures & Districts which serve as the basis for decisions by LPC and Landmark staff. The guidelines follow the Secretary of Interior s Standards for the Treatment of Historic Properties. Consult the design guidelines to ascertain if your project meets the guidelines. Infill construction in designated historic districts or Denver landmark properties reuires a minimum of two separate meetings of the Commission (LPC). This process allows for thoughtful consideration of the proposed infill by dividing the review into two manageable components Part I: Mass, Form and Context review and Part II: Design Detail Review. Pre-Review Meetings 1. Schedule a pre-review meeting with staff. A pre-app is reuired for all infill projects. 2. If applicable; for multi-unit or commercial structures, schedule a concept pre-review meeting with Development Services Project Coordination staff. Please conduct this meeting prior to filing a formal submittal with Landmark staff. 3. The Commission reuires applicants to present new infill proposals to the applicable Registered Neighborhood Organization (RNO) who choose to participate in Design Review (see staff) for consideration and feedback. Formal feedback from the RNO is reuired before submittal may be a considered complete submittal. Submit Application and Documents 4. If a proposal includes demolition, Parks Parkway review or Zone Lot Amendment (ZLA)/Site Development Plan (SDP), please submit those applications prior to the infill application. The Commission will handle those applications to the appropriate agencies prior to consideration of any other proposal. This may add extra meetings to the process. 5. Submit a completed application and the reuired components found on the Landmark Infill Submittal Checklist. Review does not begin until a complete submittal is received. Please complete all fields on the checklist and application. Applications may be submitted by , by mail, or in person. Incomplete applications delay the design review process. By Send to landmark@denvergov.org. Electronic submission should include two attachments: one PDF with the completed form ( youraddress-app.pdf ) and one PDF that combines all supporting materials ( youraddress-app-materials.pdf ). File size should not exceed more than 25 MB combined. In person: Records Counter, 2nd floor Webb Municipal Building, 201 West Colfax Ave. 8-4 p.m., Monday Friday The initial review comment period is 5 business days in which staff will communicate the status of your application and further steps. 6. Landmark staff will evaluate the completeness of an application, and perform a preliminary design guideline evaluation within 5 business days. Only applications deemed complete by Landmark staff are forwarded to the LPC. 7. For applications deemed complete, see the Basic Submittal Calendar on the next page: 3/15/16

2 Basic Submittal Calendar Sunday Monday Tuesday Wednesday Thursday Friday Saturday Submittal Deadline Staff Initial Review Staff Communicates with Applicant/Resubmittal Review Staff Communicates with Applicant/Resubmittal Review Staff Report is prepared 15 copies of revised submittal due by 9am Packets sent to Commissioners Meetings The filing deadline for the Commission is a minimum of four (4) weeks prior to each meeting. LPC meets the 1st and 3rd Tuesday of each month. One set of the application and submittal documentation is all that is reuired at the filing deadline. Once the application is cleared by staff to move on to a Commission meeting, the applicants are responsible for providing 15 hard copies of the updated submittal for the Commission at a maximum 11 X 17 size (simple stapled/no covers) at least 7 business days prior to the meeting. A digital submission to staff is also reuired. If the documentation set is not received the application is removed from the agenda. Meeting 1a. If reuested by applicant, concept discussion item for Commission consideration Meeting 1b. If applicable, demolition application Meeting 1c. If applicable, Zone Lot Amendment (ZLA) or Site Development Plan (SDP) Review of the division or combining of lots Meeting 2. Meeting 3. Meeting 4. No new information may be submitted prior to the Meeting LPC Meeting 1:00pm Mass, Form, and Context Review of application as compared to area s historic structures and context Design Detail Review to ensure that the proposed infill materials and details are compatible with the area and relate to the historic context* If applicable, final review of proposed infill updated with any conditions reuired by the Commission* * For items approved with conditions or continuances, all re-submittals must clearly demonstrate in writing and on drawings how the listed conditions/items are met. If conditions/reuired items are not provided, the submittal will be considered incomplete. 8. Once a project has LPC approval, staff will review construction drawings for conformance with this approval. Please coordinate with Landmark staff on any changes to determine if additional LPC review is reuired. 9. If the application is approved by the Commission, Landmark staff will issue a Certificate of Appropriateness (COA) after satisfactory review of construction documents to Development Services. The Commission The Commission (LPC) is a nine member Commission appointed by the Denver Mayor. The Commission meets the 1st and 3rd Tuesday of each month. At the meeting, a representative for the application is given the opportunity to address the Commission for 10 minutes. Staff can add slides to the PowerPoint presentation for applicants, but slides will need to be items that are part of the submittal packet. Any PowerPoint presentations need to be submitted to staff by the Monday, one week prior to the meeting. The Commission reuests that the submittal packet not be on the PowerPoint presentation unless there is a particular area that reuires a detailed discussion. City policy does not allow thumb drives, CD s, or laptops to interface with city euipment. Changes or alterations to submitted plans are not allowed to be submitted at Commission meeting. Changes will result in the application being deferred until staff can review changes. The Commission will deliberate the application and make a motion for approval, approval with conditions, or denial. The Commission is the deciding body for applications and their comments may differ from staff s review. Although the Commission endeavors to be brief in their application review, please be aware that some applications may have a lengthy deliberation. Standards that apply and are used for LPC review: Design Guidelines for Landmark Structures and Districts (2014) Design Guidelines for Country Club Historic District (1995) Revised Municipal Code of the City and County of Denver, Colorado; Chapter 30 Secretary of the Interior s Standards for the Treatment of Historic Properties Amendments to the Building Code for the City and County of Denver;

7 Worksheets - Context, Composition and Components of Proposed Infill Worksheets - Context, Composition and Components of Proposed Infill Infill documentation must examine the context, composition, and components of proposed new structures for compatibility with the existing historic structures of the district. These documents will examine how new infill will fit in the neighborhood. Applications submitted for infill construction must be accompanied with specific information which adeuately describes and studies the proposal. To comply with the reuired submittal standards of Denver, submitted documentation shall clearly illustrate the existing conditions as well as any proposed infill structure. Please fill in the worksheets completely. Approximate measurements are acceptable. Only contributing historic structures should be evaluated for compatibility. A contributing structure is one that was built during the Period of Significance for the district or designated property and can be recognized as being from that period (meaning they retain integrity). (Design Guidelines Glossary of Terms page C-4.) Worksheets may be customized or recreated for the specifics of each particular proposal CONTEXT 1. Ground Plan Comparison that gathers footprint size, setbacks, and a comparison to the proposed structure. The surrounding eight parcels are studied as to setback as listed. Include all structures regardless if they are contributing or non-contributing. Setbacks for new infill should correspond to surrounding context. (Guidelines 4.1, 4.2, 4.9) Question to be answered: How will the footprint of a proposed structure fit into the existing historic ground context? Please do not trespass to gather data. Stay on the public sidewalk or use aerial photographs (such as Google or Bing) to estimate measurements/ distances. Include the proposed project within the same document for comparison purposes. Notated aerial photos may also be used, however please outline the structures for clarity. 2. Street-Scape that compares the front elevation of new infill to existing neighboring structures. The neighboring 3-4 structures, on the same side of the street, should be studied. Compatibility between the new infill and the existing/neighboring historic structures should be achieved. (Guidelines 4.3, 4.4, 4.10, 4.11, 4.12, Page 80) Scaled and measured photos or drawings are to be referenced and include lines indicating primary features. Question to be answered: How will front façade design, overall height and floor to floor heights compare to existing, neighboring structures? Street-scape should include photos of structures on either side of the proposed work area (minimum of two on either side). Photos of existing structures should be of the front facade, free of vegetation, and include estimated measurements of 4 main features (foundation, entry, upper floors, and overall height). Lines of main features should be drawn across existing photos (Design Guidelines, page 80). COMPOSITION 3. Compatibility Demonstration that compares the proposed structure with existing historic structures in the historic district. This can be any supporting contributing structure in the historic district boundary, not necessarily next door or across the street. This shows the compatibility of the proposed infill by using similar style structures in the same historic district. (Guidelines 4.5, 4.13) Photos of existing structures should be of the front façade and free of vegetation. Information such as materials and estimated heights should be included. Question to be answered: How will the proposal fit within the neighborhood? CHARACTER 4. Character Defining Features is a detailed comparison of the neighborhood character defining features and the proposed structure. (Guideline 4.6, 4.7, 4.8, 4.14, 4.15, 4.16) Question to be answered: How will the components of the proposed infill correspond to the district?

11 The earliest development is from the 1870s, and includes a few wood-frame worker houses on the south end of the district. Late 1880s streetcar service stimulated growth throughout the neighborhood until the Silver Crash of This era is represented by many Queen Anne style homes and Victorian eclectic variations. After the economy recovered less elaborate styles became the norm including the Classic Cottage, Shingle Style, the Denver Suare with Classical Revival elements, and the Craftsman Bungalow.
