W S H Q FE January 18, 1993 Mr. Mike Herzig r Fort Collins Development Engineer o P.O. Box 586 M Fort Collins, CO 80522-0580 0 co Dear Mike: (File: 9202LT02) Paragon Point PUD is proposing to build 28 foot wide public streets on a number of cul-de-sac streets in the northwest portion of the development. These cul-de-sacs are named Pheasant Court, Clover Court, Catalpa Court, .and Cattail Court. According to the Fort Collins Design Criteria and Standards for Streets, this street width will require a variance by the City of Fort Collins. The reasons for requesting/granting this variance are listed below: - The streets proposed to be 28 feet wide will have less than 750 ADT on them. These cul-de-sacs would generate the following daily traffic: Pheasant Court (14 d.u.) - 140 ADT; Clover Court (7 d.u.) - 70 ADT; Catalpa Court (8 d.u.) - 80 ADT; and Cattail Court (10 d.u.) - 100 ADT. The respective generated traffic volumes would be at the point where the cul-de-sacs intersect with either Pheasant Drive or Paragon Place. These volumes are far below the threshold level in the "Fort Collins Standards." There is not likely to be any external traffic passing through this cul-de-sac. Therefore, the aforementioned traffic volumes will be a worst case level for each cul-de-sac. The streets that are proposed to be 28 feet are all cul- de-sacs. W - The cul-de-sacs do not access an arterial street. - Th-is-is-pr-imar-ily-a-large-lot_deve.l.opme.nt. The density ,? is considered to be medium (2.1 to 6.0 dwelling units per acre). Based upon criteria in "Recommended Guidelines >. for Subdivision Streets, A Recommended Practice," Institute of Transportation Engineers, 1984, the pavement o width should be 28-34 feet. The proposed 28 feet meets a this recommended practice. - Typical developments with large lot sizes provide more cc a than four, off-street parking spaces per dwelling unit. aA comparable development is the First Filing of Clarendon cc Hills. Based upon observation at various times on a • number of days, the average number of vehicles parked on Hinsdale Drive in Clarendon Hills was 3 in a length of a 1300 feet. This observation was conducted where there were dwelling units on both sides of the street. The number of parked, on -street vehicles would enable Hinsdale Drive to have been a 28 foot wide street with no traffic or parking problems. I recommend that these cul-de-sac streets in this portion of Paragon Point PUD be 28 feet wide (curb to curb). I would further recommend that parking be allowed on both sides of the streets, if at least four off-street parking spaces are provided per dwelling unit. If you have any questions or desire additional information, do not hesitate to call me. Sincerely, Matthew J. Delich, P.E.
