History
The village is on the site of Sleepy Hollow Farm, which was owned by the late J. H. McNabb, board chairman of Bell and Howell Company. McNabb's heirs sold the farm to Mr. and Mrs. Jack Polivka, who sold it in turn to Floyd T. Falese in 1953. Falese retained the services of a prominent planner and landscape architect, Raymond W. Hazekamp, who laid out a pattern of meandering roads, without curbs or sidewalks, that wound into curvilinear cul-de-sacs, avoiding the destruction of a single tree. This design retained the rural charm and natural contours of the farm and avoided taking down any existing trees. Falese developed lakes in Sleepy Hollow from existing springs and stocked them with fish. Lake Paula and Lake Sharon were the first ones completed, with Lake Ichabod dug in 1962. Falese created Lake Legend and Lake Jacqueline in 1967. The village now owns and maintains several of the lakes. Early residents of the village could keep horses on their property, with outlots used as bridle paths. The designs were carefully selected to enhance what Falese called "the Sleepy Hollow concept of good living". Falese encouraged multiple builders and custom-built homes within the community. In the 1960s many of the homes were prefabricated Scholz Design Homes constructed by the Mark 60 Corporation. Falese marketed lots in the unincorporated subdivision called "Sleepy Hollow Manor". In 1958, the residents voted to incorporate Sleepy Hollow as a separate village rather than being annexed to West Dundee. In 1958, the Faleses purchased the Petitti farm, and in 1961 the Winmoor and Whitney farms added to the family holdings. By 1960, Sleepy Hollow's population was 311. By 1970, it had grown to 1,729. The only commercial activity was the Sleepy Hollow Resort Motel and Crichton's Super Mart. In 1966, the Glen Oak Country Club was opened as a member-supported outdoor pool facility Later, the Sleepy Hollow Elementary School was opened adjacent to the pool. The Sleepy Hollow population continued to increase through the 1980s and 1990s as the remaining lots in Falese's original subdivision were developed and as three other adjacent subdivisions were annexed: Saddle Club Estates, and Surrey Ridge and the Bluffs. Sleepy Hollow's ability to annex additional land to the west and south is limited by an agreement with the city of Elgin, which also provides for the city to supply water to the village. Sleepy Hollow has had its own police force since the 1960s. For years, it was a one-man force: Larry Sabatino Jr., the second police chief. The village named a park in his memory. On March 9, 2014, the Sleepy Hollow police force had its first fatal shooting in a domestic disturbance case.
Subdivisions in Sleepy Hollow
The main subdivisions in Sleepy Hollow are:
Deer Creek, a subdivision started in the 1990s by Windsor Development, and then became a custom home subdivision.
Saddle Club Estates, a subdivision built in the late 1980s by Pulte Master Builders featuring a park, green space, wooded lots, and some English and walkout basements.
Sleepy Hollow Manor, the original subdivision to Sleepy Hollow still has some vacancies.
Surrey Ridge, a condo, coach home, and single family subdivision started in the late 1980s by Windsor Development.
The Bluffs, the newest subdivision in Sleepy Hollow, featuring semi-custom and custom homes.
Financial troubles
As of 2016, the village was facing financial hardships. All the money in reserves and contingency funds had been used up. Street lights were not being replaced, mowing of parks had stopped, and outside contracting had been limited as much as possible. It appeared that there were three options for the village: being annexed to a neighboring municipality; unification with another village to form a separate entity; or dissolving the government altogether, to become an unincorporated part of Kane County. To keep Sleepy Hollow afloat, and keep it as its own village, officials asked for a property tax hike. At the Village Board meeting on March 7, 2016, the motion was passed to allow sheds and certain fences with restrictions.. By allowing sheds and fences, the village would be able to generate revenue through permit costs. As of late 2016, Sleepy Hollow had created a plan, allowing them to maintain financial control without choosing any of the options from March. Street lights were replaced with new energy-efficient models. A car dealership and gaming cafe were set to open in 2017 on Route 72. As of August, 2019 sheds and fences are still not permitted.
Gardens
As a way to connect with residents, Sleepy Hollow operates a community garden, which rents garden plots to residents for personal gardening. The village also maintains the "Giving Garden", from which produce is donated to local food pantries. As part of the rental agreement for the community garden, renters must volunteer at the Giving Garden.
