S:;nuett We ; d County Colorado Department of Planning Services • 915 10th Street Greeley , CO 80631 RE: Case Number: Amended USR-478 Robert 3r Katherine Johnson • Richard & Marcia Chana Dear Mr . Schuett: Soils have a loam and clay loam surface texture . Water movement into and through these soils is slow . After wetting , these soils should be allowed to dry out on the surface before animals are turned out into the pen . A permanent grass cover would provide a mat for the cogs to walk on which would help control mud . At present, the large pen and other pen on the north side of the Staney Ditch appear to be covered with grass . All land inc l ud i ng the fenced in area should be managed to maintain a grass cover to prevent wind and water erosion and to prevent undesirable plants from growing such as stickers and burs . Noxious weeds should he controlled at all times. The individual dog runs on the south side of the Stanley Ditch are getting bare of vegetation . These are small and should not be a problem. However, if more dog runs are built , a grassed area needs to be left between the existing and new runs to help prevent erosion . Ail roads or trails to the pens should be gravelled or hard surfaced to help prevent erosion .
