BACKGROUND Ponderosa Homes applied and was granted a general plan amendment in 2002 to construct approximately 190 single-family homes, 172 unit senior apartments and a church/daycare on the Busch Property. As part of this approval, several off-site infrastructure improvements were required to maintain satisfactory levels of service on the roadway network. These improvements included: • Modifications to the Valley-Busch intersection; • Signalization of the Boulder-Valley intersection; • Modification of the Stanley-Valley-Bernal intersection; • Modification of the First-Ray-Vineyard intersection; • Modification of the Bernal-First-Sunol intersection; • Modification of the Stoneridge-Hopyard intersection; • Modification of the Stoneridge-Hacienda intersection. Of these mitigations, the Stanley-Valley-Bernal improvement and the Bernal-First-Sunol improvements have not been completed. DISCUSSION The conditions of approval for the Busch Property Development (PUD-18) required Ponderosa Homes to complete several off-site traffic improvements, most of which have been completed. The final two items to be constructed include: Item J -The Valley-Stanley-Bernal intersection shall be modified in a manner to ensure LOS D at AM and PM peak hour periods by constructing a free westbound to northbound right turn lane with corresponding changes or an alternative capacity enhancement approved by the City Traffic Engineer. Item L - The Bernal-First-Sunol intersection shall be modified to include westbound triple left turn lanes with corresponding changes or an alternative approved by the City Traffic Engineer to achieve LOS D at AM and PM peak hour periods Ponderosa is moving forward with Item J and have requested confirmation (see attached letter) that the Bernal-First-Sunol project is a necessary project, and if it is not, than the existing bonds be exonerated. Staff has reviewed item L and has determined that a triple westbound left turn is not necessary, however, construction of a second westbound left turn lane as an alternate improvement is necessary to achieve LOS D in the AM and PM peak hour periods. The design work completed by Ponderosa Homes was for the construction of a second westbound left turn lane. The construction of the second westbound lane will require the removal of the existing heritage trees along the north side of the intersection. While staff believes the intersection level of service would benefit significantly from the construction of the Page2of3
