Bridgefield P.U.D. page 2 Sub —Basin "F" lies West of South Bryan Avenue and will be regraded to all drain Southerly to proposed inlets, and a pipe will carry the runoff under the Larimer County Canal No. 2 to the existing West Heathridge Apartment Pond. Sub —Basin "G" lies East of South Bryan Avenue and will also be regraded to all drain Southerly to the proposed inlets and pipe to cross the Larimer County Canal No. 2. Sub —Basin "H" is the West part of the area to be developed below and South of the Larimer County Canal No. 2. The 3.10 acres will drain Southerly to the West end of the existing West Heatheridge Pond. Sub —Basin "I" is the East part of the area below and South of the Larimer County Canal No. 2. Sub —Basin "I" will drain to an inlet at the Southeast corner of the sub —basin and then in the proposed storm drain to the East end of the existing West Heathridge Pond. The pond will be enlarged to detain the difference between the two year historic and the 100 year developed runoff for Sub —Basins "F," 11G,11 "H" and 111 . 11 Sub —Basin 11J11 is open space in the drainageway, which will remain undeveloped. The difference between the two year and 100 year historic flows will be detained in the pond. Sub —Basin 11K" is the area for five proposed lots lying North of West Stuart between the New Mereer Ditch and the Larimer County Canal No. 2. It will drain from West Stuart Street Westerly to an inlet at the end of the cul de sac and then in a pipe under the Larimer County Canal No. 2 to the detention pond. It is proposed to cut a fairly large part of the site above the Larimer County Canal No. 2 and move that material across the canal and fill a fairly large part of the site below the canal. This grading will be done from November 1994 to April 1995 while the ditch is not running irrigation water. A silt fence will be placed along the canals and along the pond during construction for erosion control. The inlets will have straw bales and rock filters around them during construction. Due to the overlot grading proposed, the area that is disturbed, and not the initial lots to be built on, will be reseeded. The runoff calculations and the grading and drainage plan are enclosed as a part of this preliminary drainage report. If you have any questions regarding this proposed P.U.D., please call.

Box 580 Fort Collins, CO 80522 Dear Basil: The following is the preliminary storm drainage report for the proposed Bridgefield P.U.D. situate in the North i of Section 22, Township 7 North, Range 69 West of the 6th P.M., Fort Collins, Colorado. The site is in the Canal Importation Drainage Basin. The P.U.D. is bounded on the North by West Prospect Street and on the East by an existing residence and the Larimer County Canal No. 2 and Heathridge Apartments. It is bounded on the South by the New Mereer Ditch and West Stuart Street and on the West by the New Mereer Ditch and the Bridges P.U.D. The site is proposed to be developed with single fancily detached residences on small lots. It is divided into three different topographical areas. The North area lies between West Prospect Street and the Larimer County Canal No. 2 and is the higher ground. It has two historic sub —basins. Sub —Basin "A" drains Northerly from an abandoned irrigation lateral to Prospect Street . Sub —Basin "B" drains Southerly from the abandoned irrigation lateral to the Larimer County Canal No. 2. The middle area, Sub —Basin "C," lies below and Southerly of the Larimer County Canal No. 2. It drains Southerly from the Larimer County Canal No. 2 to the existing drainage way that traverses through the Heatheridge Apartments. Sub —Basin "D" lies North of West Stuart Street between the New Mereer Ditch and the Larimer County Canal No. 2. Sub —Basin "D" drains into the Larimer County Canal No. 2 It is proposed to divide the P.U.D. into seven developed sub —basins. Sub —Basin "E" is the existing West Prospect Road pavement and a small amount of landscaping that drains into the South flow line of West Prospect Road. The area of the sub —basin is 0.96 acres, and its runoff will not be detained. James H. Stewart and Associates. Inc. 103 S. Meldrum Street P.O. Box 429 Ft.
