Almeria/Willetta Drainage Studies

Drainage complaints from the two owners located along Almeria Road and Willetta Street prompted the City of Phoenix to investigate the cause and possible solutions. Hoskin Ryan performed a review of the existing storm drainage systems and local watershed areas affecting local flooding conditions. Alternatives and cost estimates were prepared and upgrades to the existing storm drainage systems recommended which resulted in improvements to local ponding scenarios. The capacity of the 27th Avenue storm drain was assessed in conjunction with an evaluation of potential outfalls to either the I-10 collector channel, or the 35th Avenue storm drain.
