PENCO provided the City of Pomona with a complete inventory of the its alleys. The compilation of data was completed and submitted to the City in 2003. In 2008, PENCO was awarded the Citywide Alley Improvement Project based upon the initial inventory. PENCO then proceeded to work in conjunction with the City to complete this extensive improvement project that included the rehabilitation of 45 alleys totaling 24,000-linear feet throughout the City. PENCO also assisted the City in obtaining rights of entries from residents whose properties needed to be accessed in order to accomplish the survey and construction of the alleys. Design Services included: preparation of plan and profile sheets for all of the alleys; geotechnical investigation reports; environmental documentation supporting California Environmental Quality Act (CEQA) requirements; preparation of a Standard Urban Management Plan (SUSMP); Stormwater Pollution Prevention Plan (SWPPP) reports; potholing of existing utilities; bid support; and construction support.

PENCO also coordinated the relocation of six power poles, and telephone and cable lines. Additionally, PENCO prepared and attended community meetings outlining impacts of this project on each individual property owner, and had several one-on-one meetings with the owners to resolve their concerns.
The most challenging aspect of the project was to maintain the longitudinal and cross fall minimum grades and still preserve the elevations at the access points into private properties. PENCO worked closely with the City to develop design criteria to minimize the impact on private properties. PENCO also coordinated this work with each individual resident that was impacted by our design by having individual meetings to explain our best design criteria and answer any questions they had.
