I I I '1 I I I I I I I I I Ms. Anita Ffamussen Page 5 April 4, 2000 The one-way street system will limit the lawful vehicle access back and forth between the two developments. Modifications for Alternative Street Layout #4 Like Alternative #3 just discussed, Alternative #4 eliminates the cul-de-sac at the south end of Argon Street (south of 142nd Ave.) and Barium Street is terminated in a similar fashion south of 141st Avenue. As a result, there is no direct vehicle link between Mallard Ponds and the existing neighborhood to the north. The traffic volume impacts of the Mallard Pond Development on the area streets is shown graphically on Exhibits F (exiting traffic) and G (entering traffici. Except for the elimination of all Mallard Pond Development trips on 141st Avenue and Barium Street (18 daily trips), the daily, a.m. peak traffic hour and p.m. peak traffic hour volumes are unchanged from those of Alternative Layout #3. However, the traffic operational and traffic safety issues become much more significant as noted: No secondary means of emergency vehicle access is provided for any of the fifty seven (57) twin and detached single family residences within Mallard Ponds and the resulting dead-end street far exceeds the City's maximum 600' length; No vehicular circulation is available for trips between the two adjoining residential developments without accessing the perimeter street system; and No turn-around is provided on the south end of either Barium St. or Argon St. for the existing developments to the north. Therefore, ail non-local traffic will either have to turn around in the private driveways or back up to the last intersection. And again, any backing up maneuver is inherently more dangerous for the local residents and their property. If you have further questions, need additional information, or wish to discuss this matter in greater detail, please contact me. Thank you for the opportunity to serve you on this matter.
