DescriptionThis data is designed to assist preparing the SWMP for projects and supply Maintenance projects that need seed mixtures for work along Region 2 highways. Also, these seed mixtures are available in a digital format in ARC/GIS layer for CDOT’s OTIS Highway Map System. The intended users are Environmental, Engineers, and CDOT maintenance staff. However, there are limitations and assumptions that were considered when developing these seed mixtures. Assistance from the environmental staff is strongly recommended before using a seed mixture. Site specific conditions may require adjustment to the seed mixture(s).

The seed mixtures contained in this dataset are designed for the site specific conditions (e.g., soil texture and chemical composition, precipitation, elevation, aspect, etc.) associated with the approximate mile marker along Region 2 highways. Native species were selected for the seed mixtures with few exceptions. The individual plant species were selected based on their adaptions to the site conditions, ability to control erosion, and compatibility to establish a diverse plant community. The species composition of the seed mixture was also based on the recommendations found in the Natural Resources Conservation Service’s (NRCS) “Major Land Resource Areas (MLRA).”(http://www.nrcs.usds.gov)

DescriptionCDOT staff and consultants collect wetland boundary data for project development. This data is limited to wetland delineations completed for CDOT projects and CDOT/FHWA-funded projects beginning in 2017 with a few exceptions dating before 2017.

Disclaimer/LimitationsAbsence of wetland polygons within an area does not indicate absence of wetlands. Additionally, wetland delineations legally expire after five years. Data found on this GIS platform should not be used in lieu of field investigations.

The spatial point data is aggregated by the State of Colorado Governor's Office of Information Technology Geospatial Information Systems Team. This dataset represents an on-going relationship between the counties, municipalities and the State of Colorado to provide accurate updated address information. Updates are collected annually. This data layer reflects an evolving data model of the Colorado State Address Dataset (CSAD).
