Conservation Analysis
Request for Exemption from Conservation Design
673 Crescent Avenue Subdivision · Tax Map 180.69-2-22 · City of Saratoga Springs, NY
Project
The applicant proposes to subdivide the ±1.10 acre parcel at 673 Crescent Avenue, in the RR
District, into two single-family residential lots. Conservation design is required for subdivisions in the
RR District (UDO § 240-16.2). This analysis is provided for the Planning Board’s determination
under § 240-16.7 that conservation design is not required.
Constrained Land (§ 240-16.5) – Figure 1
There is no constrained land on the parcel. No wetlands, watercourses, or 100-year floodplains are
mapped on the parcel. Slopes over 15% on the parcel total 1,858 sf (1,958 sf contiguous), below the
2,000 sf minimum.
Conservation Features (§ 240-16.6) – Figure 2
Conservation features are summarized in Table 1. Soils are detailed in Table 2.
Exemption from Conservation Design (§ 240-16.7)
Acreage (§ 240-16.7A.2)
At 1.10 acres with no constrained land, a conservation design would place a minimum of 0.55 acres
in a conservation easement. The parcel is too small to preserve a substantial amount of land with
conservation value. The property is an existing tax parcel and is not being divided from a larger tract.
Adjoining land (§ 240-16.7B)
The parcel is bounded by Crescent Avenue and Inlander Road and adjoins residential lots and
Interlaken HOA land. None of the adjoining land is mapped by the City as preserved open space or
as part of a designated trail corridor. Open space on this parcel would not combine with adjoining
land to preserve a substantial amount of land with conservation value.
The applicant requests that the Planning Board find no reasonable basis for requiring conservation
design and allow the proposed two-lot conventional subdivision.

Table 1. Summary of Findings
Resource Finding
Constrained Land (UDO § 240-16.5) – Figure 1
Wetlands None on the parcel or within 200 ft (USFWS NWI; NYSDEC).
Watercourses None on the parcel or within 200 ft.
100-year floodplain None on the parcel. A small portion of the Zone AE floodway lies within 200
ft, ±190 ft from the parcel (FEMA Preliminary FIRM, 01/31/2025).
Steep slopes (>15%, ≥ 2,000
sf contiguous)
None qualifying. Slopes over 15% on the parcel total 1,858 sf (1,958 sf
contiguous), below the minimum.
Total constrained land 0 ac
Conservation Features (UDO § 240-16.6B) – Figure 2
Sensitive soils Windsor loamy sand, 3 to 8 percent slopes (WnB), entire parcel; classified
as farmland of statewide importance. See Table 2.
Wetland buffers None; no wetlands on the parcel or within 200 ft.
Woodlands ±0.9 ac of the parcel is wooded. Trees 4"–30" DBH; mixed deciduous with
scattered conifers.
Rare / threatened /
endangered species
None known on the parcel; none mapped on or within 200 ft (NYSDEC
ERM).
Wildlife
No survey conducted. Wildlife typical of suburban woodlots is expected. The
City NRI (2020, Map 7.3) maps a terrestrial wildlife corridor that includes the
parcel.
Cultural / historic
Within an archaeologically sensitive area; no State or National Register
listed or eligible resources on the parcel or within 200 ft (NYS OPRHP
CRIS).
City plans
The Open Space Plan (2023) shows a proposed bike route on Crescent
Avenue and a 100-ft stream buffer south of Crescent Avenue; neither is on
the parcel.
