About this file
This is an Erosion Control Plan prepared for the City of Cheyenne, Wyoming, Community Recreation and Events Department in support of the North Cheyenne Community Park Drainage Improvement project. The plan details erosion control measures for Lot 2, Block 1 of the North Cheyenne Community Park, located at the northeast corner of Storey Boulevard and Chief Washakie Avenue in Cheyenne, Wyoming. The project encompasses drainage improvements designed to address standing water issues in the park through removal and replacement of existing pipe and manhole infrastructure, installation of a riprap pad, grading, and resodding of disturbed areas. The erosion control plan was prepared as of August 8, 2025, with a grading permit dated October 15, 2025, and identifies limits of disturbance, construction entrance points, materials storage areas, and control measures including silt fencing and straw bales positioned downgradient of storage piles and disturbance areas.
The plan specifies that all erosion control measures must be installed and maintained in accordance with Section 01563 of the City of Cheyenne—BOPU Standards and Specifications (2022 edition or current) with latest amendments and modifications. The site construction entrance is designated just north of the maintenance gate, positioned east of the sidewalk on the north side of the paved parking lot. The plan includes design specifications for new culverts, manholes with flared ends, riprap pads, and associated grading and drainage infrastructure necessary to address the existing drainage deficiencies within the park boundaries.
