The Licensed Contractors dataset contains all contractors currently licensed by the City of Boulder, including General Contractors for construction projects, Electrical Contractors, Mechanical Contractors, Plumbing Contractors, Right of Way Contractors, Fire Contractors, Tree Contractors, Sign Contractors and Rental Housing Licensed Inspectors. All contractors who are issued a license have provided proof of certifications and insurance as required by City of Boulder Municipal Code to qualify for that type of license. Work completed through a permit in the City of Boulder requires a licensed contractor.Contractor Licenses are valid for a one-year period. Licensed Contractors are required to carry General Liability Insurance and Workers’ Compensation if they have employees, as well as valid certifications as required by license type. A license in an “issued” status is current with all requirements and will be able to apply for permits and schedule required inspections. A license in “insurance expired” status may still be in their annual license period; however, they will not be able to apply for permits or schedule inspections on existing permits due to expired insurance. Insurance policies often run on a different annual term than a contractor’s license. Once an updated policy is submitted to the city, the contractor’s license will be updated to “issued” status. It is the responsibility of the contractor to maintain the insurance requirements for the City of Boulder.Several supporting files can be used with this dataset for extra context:Data DictionaryDictionary of classifications for types of contractors

The lakes and reservoirs in this dataset were conflated from various data sources, including NHD, Colorado Department of Natural Resources Division of Water Resources (CDSS), Boulder County, City of Boulder and individual ditch companies. The data was verified with field visits and extensive staff knowledge. The data includes links to various internal databases, as well as the Colorado Division of Water Resources database. Pre and Post 2013 Colorado Flood alignments are included. This data is appropriate for both small and large scale usage.

This dataset contains emails sent by community members to City Council as well as staff and council responses to those emails.Note: All emails to council@bouldercolorado.gov are public record. Emails sent to individual council members are not included. Email addresses and phone numbers are automatically hashed with a long alphanumberic string in the data for privacy reasons.

To link physiographic variables to lithology and trail characteristics (Objective 2), we created process domain maps and used principal component analysis considering physiographic variables such as slope, topographic position index (TPI), and concavity as a function of lithology and trail type. All metrics were calculated using ArcGIS Pro and lidar collected 2013 by McKim & Creed Inc. for City of Boulder. High-resolution lidar data can be useful in determining different types of processes, ranging from slow creep to landslides (Booth et al. 2009; Booth et al. 2013) and variables like slope highlight areas where mass movements are likely to occur. Similarly, concavity, or landscape curvature, indicates where advective versus diffusive processes occur, correlated to convex versus concave landscapes, respectively (Dietrich and Perron 2006; Sweeney et al., 2015). Concave processes are dominated by diffusive movement (slope-dependent transport; Dietrich and Perron 2006). These processes are competing against one another on the hillslope and give rise to diffusion-dominated ridges and advection-dominated valleys (Dietrich and Perron 2006; Sweeney et al., 2015). The TPI is a landform classification used to determine roughness indices like valleys and ridges in the study area. The TPI was calculated at different resolutions (5-m, 10-m, 50-m, 100-m) to see if different hillslope attributes were identifiable at the different scales. To calculate the TPI, the mean for each resolution was subtracted from the Digital Elevation Model (DEM). Derived physiographic variables and GIS data products can be found in this repository.
