Outdoor Living on Chicago's North Shore

Five glacial moraines step down to Lake Michigan here, and where the last of them meets the water, roughly a dozen deep ravines cut the bluff between Winnetka and Lake Forest — the only landscape of its kind in the region, and the reason this market regulates backyards like no other in Illinois. The Green Bay Trail running its length is older than every town on it, tracing a shoreline route that predates each municipality’s charter. Backyard Paradiso serves nine communities across Cook and Lake counties as the Chicago North Shore & Lake County designation on its Markets We Serve roster.

The four shore towns south of the county line pair the market’s oldest housing with its most formal design review — these are municipal preservation commissions issuing certificates of appropriateness under village code, a public process, not the private architectural committees most suburban markets run on. Evanston anchors the band in more ways than one: its water plant, drawing from intakes off the lighthouse point, treats over a hundred million gallons a day and wholesales to more than four hundred thousand people — including, by pipeline, the commission towns of the adjacent northwest suburban market. Its adopted code writes the forty-two-inch frost depth into local ordinance. Wilmette holds two landmarks of world rank within a few blocks — the Baháʼí House of Worship on Linden Avenue and Frank Lloyd Wright’s 1909 Baker House — yet has never designated a local historic district, because its code requires the consent of three-quarters of a proposed district’s owners, a threshold no neighborhood has cleared. Winnetka wrote shade-tree planting into its village charter in 1869, the root system, so to speak, of the modern North Shore tree ordinance. Glencoe — the self-styled Queen of the Suburbs, the first Illinois village to adopt council-manager government in 1914 — was laid out to harmonize with its ravines rather than bridge them, still builds under the market’s oldest code edition, and holds the Chicago Botanic Garden: 385 acres of lagoon-and-island garden run by a horticultural society founded in 1890, opened to the public in 1972.

North of the county line the ravines deepen and the ordinances follow them down. Highland Park has regulated its steep ground since 2001, when Ordinance 38-01 drew a Steep Slope Zone in which earth moving and structures are prohibited outright, retaining walls above sixty inches require an engineer’s design, swimming-pool discharge must route to the sanitary sewer rather than the ravine, and projects near the zone carry a hydrological control plan. Its tree code protects anything of eight inches diameter and elevates heritage specimens by species — oaks at thirty inches, hickories at twenty, walnuts at thirty, elms at forty — and its residential code moved to the 2024 edition this past March, making it one of the market’s two most current jurisdictions. Highland Park is also where the market’s outdoor culture was invented twice: Ravinia has run since 1904 as North America’s longest-running outdoor music festival, thirty-six acres organized around the lawn picnic, and at 930 Dean Avenue the landscape architect Jens Jensen worked native stone into the council rings that became the signature of the Prairie style’s outdoor rooms. Lake Forest, next door, regulates the ravines with the market’s most explicit numbers: Section 159.015 keeps foundations twenty feet back from a ravine edge and seventy-five from the bluff, bars construction entirely within twenty feet of a ravine and fifty of the bluff edge, and — a rule with no counterpart anywhere else on the roster — prohibits topping trees to open a lake view. Ravine and bluff trees carry their own permit chapter, and protection fencing to a written specification goes up before ground breaks. The town itself was planned in 1857 by Almerin Hotchkiss across ten ravines, refined by the Olmsted firm’s successors, and centered since 1916 on Market Square — recognized by marker as the country’s first artfully designed shopping center, Howard Van Doren Shaw’s work.

Off the lake plain the ravine rules give way to watershed rules. Deerfield, which followed its neighbors onto the 2024 code in the same March window, runs the band’s most particular permit catalog: a raised deck or a pool must stand eight feet off the lot line — a setback that rearranges small backyards — and Section 6-9 bans construction work on Sundays outright. Libertyville carries the threshold that surprises the most homeowners: under its stormwater appendix, four hundred square feet of new impervious surface triggers detention design — a threshold a single modest patio can cross. Vernon Hills adopted the 2024 residential code by Ordinance 2026-008, effective this past March, joining Highland Park and Deerfield on the market’s most current rulebook. All three sit under the Lake County Watershed Development Ordinance, whose erosion-control provisions engage at five thousand square feet of disturbance, and all three drink Lake Michigan through the central Lake County joint water agency rather than their own intakes — the inland shelf’s version of the shore towns’ lakefront plumbing.

Forty-two inches below grade is where footings start across this market — the frost depth written into Evanston’s and Highland Park’s amendment ordinances and the working minimum for pergola posts and structural columns throughout. Snow governs by design load rather than snowfall totals, and the governing value depends on which code edition the jurisdiction adopted — a live question here, because the market currently builds under a decade-wide spread of editions at once, from Glencoe’s 2015 baseline to the 2024 codes Highland Park, Vernon Hills, and Deerfield began enforcing in March. Illinois layers a recent statewide stringency floor beneath its municipal codes, weathering is classified severe, and the lake writes its own microclimate: the shoreline records barely a third as many ninety-degree days as O’Hare in a typical year, which stretches the comfortable season on a bluff terrace and shortens the establishment window for spring plantings. Freeze-thaw cycling remains the defining hardscape stress, compounded along the shore by de-icing salt tracked across the same walks and terraces the runoff rules protect — a chemistry argument for dense pavers over cast-in-place concrete that this market’s conditions make better than most. Wetland review moved to the county after 2023 — on this roster that means the Lake County ordinance and its commission process for isolated wetlands that fell out of federal jurisdiction. And beneath every one of these rules sits the quiet fact that distinguishes this market: the review is public. A ravine-lot project here can pass through a preservation commission, a steep-slope screening, and a village engineer’s stormwater desk before the first footing is poured — sequencing that rewards a design brought in complete rather than permitted piecemeal.

Backyard Paradiso serves all nine communities with its full service line; these are the North Shore’s natural leads. Glass railings answer the market’s defining condition — code-required guarding that keeps a ravine or lake view intact, engineered for wind exposure at the bluff edge. Pergolas — aluminum-framed as standard — carry real snow loading on forty-two-inch footings, and pavers ride the freeze-thaw calendar on drainage-first bases that respect steep-slope runoff rules. A retractable awning and motorized zip screens tune a lakefront terrace to wind and glare hour by hour, while patio outdoor umbrellas and outdoor furniture furnish the lawn-picnic culture this market practically invented. Fence lines negotiate tree-protection zones and ravine setbacks, and landscape lighting works the long dusk under mature canopy that tree ordinances have spent a century and a half protecting. Where guarding, floor, shade, and light arrive as one project, the Complete Outdoor Living Systems approach carries the whole scope through preservation review, steep-slope screening, and the right village’s permit sequence as a single engineered design.

Every engagement begins with the parcel’s position — shore, bluff, or shelf — its distance to a ravine edge, and the code edition its village enforces this season. Consultations across the Chicago North Shore & Lake County designation are available by appointment. West at the Wilmette–Glenview seam, the Chicago Northwest Suburbs designation carries the roster inland to the commission towns and the well country beyond.
