Page 3 of 4 4. Do we have a synopsis of the issues that have come from other residential areas served by the County (Happy Valley, Remen Tract, and Castlewood)? The city is frequently approached by owners of parcels within the Castlewood, Happy Valley and the Remen Tract areas seeking to connect to City water and/or sewer services. Applicants are usually seeking connections to support property development (e.g., subdivision of land, construction of a new home, or significant enlargement of an existing home). In other cases, a property owner may have an existing on-site well or septic system that is aging, expensive to repair/expand, or may have failed. Connections to City water and/or sewer lines are granted through Out of Area Service Agreements (OASA), alternatively referred to as Preannexation Agreements. Although an OASA provides a convenient method to allow property owners to take advantage of public utilities (well and septic systems are inherently less desirable from an operations, maintenance, and public health perspective), allowing such connections places burdens on City services, and facilitates growth in areas typically poorly served by public services (e.g., law enforcement, fire protection). More broadly, recipients of OASA remain residents of Alameda County while taking advantage of City water and sewer services, and in all likelihood, Pleasanton schools, parks, streets, and other amenities. These County residents do not contribute the same share of property taxes as properties in Pleasanton, are not subject to City development requirements (except where required to abide by them by policy), code enforcement or similar authority available to the City within its boundaries, and neither elect nor are represented by City of Pleasanton officials. Staff generally recommend prioritizing applications of OASA based on health and safety considerations (e.g., failing septic system, demonstration of unacceptable contamination in groundwater), and deprioritizing/discouraging OASA for the sole purpose of subdivision, major expansion of a home that requires additional sewer or water capacity, or construction of additional units on a property. The Castlewood community is currently connected to and served by City of Pleasanton water. The sewer collection system is owned and operated by the private property owner’s association. Sewer flow is pumped to Pleasanton’s system and ultimately pumped to the DSRSD treatment plant. 5. Describe the elevation change between the Ironwood development and the proposed Arroyo Lago project, including the proposed fence heights. The Arroyo Lago preliminary plans submitted to City staff do identify a grade change between Ironwood and Arroyo Lago ranging from approximately 6.1 feet to 1.8 feet. The higher elevation occurs near the north end of Arroyo Lago, which adjoins 1558 and 1564 Chatham Place; the site then slowly descends (traveling south) to a difference of 1.8 feet at 1344 Chatham Place. The Arroyo Lago project’s civil engineering team has designed the on-site sewer system to flow from the northern portion of the site toward Busch Road and connect to the sewer system in Busch Road, resulting in increased grades/pad heights at the northern portion of the site. The Ironwood residents currently have a 7-foot-tall stucco wall that will remain in place. Due to the grade difference described above, the Arroyo Lago project proposes to construct a retaining wall on its side, ranging from 6.1 feet to 1.8 feet tall, along with a 6-foot-tall ‘good
