plan was approved by the village board on July 2, 1962. Units 2, 3 and 4 followed in 1964, 1966 and 1968. One acre home-sites sold for $10,000. On the west side of Quentin Road, the grazing land where Jersey cows would spend hot summer days sleeping under oak trees also succumbed to development. Subdivision of Pine Valley Unit I was approved in 1964, Unit 2 in 1967, Unit 3 in 1969, Unit 4 in 1972 and Unit 5 in 1976. Kildeer had hoped the area would remain unspoiled, but progress was quickly approaching, and the village had to prepare itself with controlling subdivision, building and zoning ordinances as well as a master plan for development. Facilities To dispose of sewage, all Kildeer residences had septic fields. Soils in the area were of the type considered "extreme" for this purpose, and septic fields in general in Lake County were experiencing difficulties, adding to the pollution of local streams, rivers and lakes. The Lake County Health Department progressively increased their standards to eliminate a growing problem. A longtime resident and Kildeer trustee, Frank Angelotti, had his own civil engineering company doing consulting work for other villages. He was aware of federal funds available through the Illinois Environmental Protection Agency (IEPA) to assist municipalities in the construction of local sewers. Early in 1975, Trustee Angelotti, at his own expense, prepared schematic drawings of a sewer system for the entire village of Kildeer. The system would tie into a new Lake County interceptor sewer to be installed on Quentin Road for relieving Lake Zurich's sewage treatment plant. Lake County, by agreement and service charges, would provide all sewage treatment. He presented his plan to the Kildeer Village Board. In addition to serving Kildeer, it was proposed to extend sewers to Rand Road. Having the only sewer system in the area would give Kildeer complete control of any and all development along Rand Road and its surrounding borders. The residential system was designed for 4½ people per acre which would limit and control the density of residential development. If approved, the IEPA would provide 75% funding for the project. Seeing the merits of this project and the fact federal funding would be a one-time opportunity, the village board moved to submit an application to the IEPA. The construction estimate was $1,811,000, of which Kildeer's 25% share would be $452,750, or $834 per residential lot.
