Harmony provided Construction Phase services that encompassed preparing a Stormwater Pollution Prevention Plan (SWPPP) in accordance with EPA requirements for construction sites greater than one acre, construction observation and documentation as required by the City of Victor, organizing a pre-construction meeting with City staff and contractor, reviewing RFI’s and submittals, preparing record drawings and approval checklists for submittal to the City.
West Little Avenue Streetscape Improvements - Driggs, Idaho
The West Little Avenue improvement project was designed using the latest standards and best practices set forth by the National Association of City Transportation Officials (NACTO), the American Association of State Highway and Transportation Officials (AASHTO), and the Manual of Uniform Traffic Control Devices (MUTCD). A public open house was held in a highly visible storefront in order to gather feedback on design elements such as sidewalks, bike lanes, landscaping, pedestrian amenities, parking, and civic space. Harmony worked with the City of Driggs to develop the concept plan used to guide construction. In the end, an attractive and inviting environment for tourists and residents with a focus on pedestrian and bicycle safety was constructed using final engineering drawings completed by Harmony. These included demolition plans, grading plans, drainage plans, roadway plans, utility plans, landscaping plans, and signage and striping plans. Creative stormwater drainage solutions for the street included the use of bioinfiltration swales between parking areas and sidewalks. The project was funded by Idaho Transportation Department grants and was completed in early winter 2015. The project was awarded a 2017 Idaho Smart Growth Grow Smart Award in November 2017.
Pathway Missing Links - Driggs, Idaho
The Driggs Missing Links Pathway Connection Projects A, B, and C consisted of three separate pathway and sidewalk connections that completed a continuous multimodal pedestrian and bicycle connection through Downtown Driggs from the Creekside Meadows Subdivision north to the Driggs Airport. This pathway system consisted of a combination of 8-ft wide concrete sidewalks and 10-ft wide separated asphalt pathways, and involved numerous at-grade crossings of busy collector roads and business accesses and one at-grade crossing of Idaho SH-33. The at-grade crossing of Idaho SH-33, the busiest section of road in Teton County, Idaho, required coordination with the Idaho Transportation Department. Additionally, the project required the resolution of multiple utility crossings and the design and specification of a concrete box culvert at an irrigation canal crossing. Harmony provided preliminary and final engineering design and construction documents, as well as assistance with bid solicitation, contractor selection, and construction administration. This pathway was designed using the latest standards and best practices set forth by the National Association of City Transportation Officials (NACTO), the American Association of State Highway and Transportation Officials (AASHTO), and the Manual of Uniform Traffic Control Devices (MUTCD). Construction of the three pathway connections was completed in 2015 and 2016.

Hailey River Street Revitalization - Hailey, Idaho
River Street is an underdeveloped business district the Hailey downtown core which currently lacks basic pedestrian facilities. Harmony Design & Engineering assisted the City of Hailey with an Idaho Department of Commerce Community Block Grant application by providing conceptual engineering and landscape plans for the River Street Improvements. Harmony staff facilitated charrette style public workshops, held small meetings with stakeholders, and facilitated a design workshop that focused on the design for River Street. Based on all of this input, the River Street improvement plans were developed with the goals of slowing down traffic, increasing pedestrian and bicycle safety, improving storm drainage, and beautifying the downtown area, all in the hopes to attract business. The workshops resulted in strong community support for the project.
