A subdivision cove is bulb of lots that is pushed back from the road to enable narrow frontages while maintaining desirable widths at the setback of the buildable area. Coves are most conveniently located on the outer side of a curved piece of road.
Coving is used as an alternative to conventional "grid" subdivision layout in order to reduce the improvement costs of additional utilities and road surfacing, as well as to improve aesthetics and to give all lots direct access to parks and open areas.

History
Coving was pioneered by Minneapolis-based urban designer Rick Harrison. The term emulates the nautical description of a cove as an indent in a body of water, or in this instance, an indent along the setback line.
The Roman Empire employed grid-systems for city planning which used narrow street-frontages with long plot depths. The burgage plot pattern of English town development kept roads apart, with long narrow buildable areas created (in a comb-like pattern) between them, ensuring that as many properties as possible had immediate access to a right of way. Both of these antecedents employed methods to minimize road right-of-way for the number of lots, but neither method was able to provide sufficient width at the buildable area for a more cost-effective square shaped house. When effectively designed, a coved neighborhood will achieve both a decrease in roadway area and the minimum widths necessary for an efficiently designed house at the building setback.
Design
A coved neighborhood maximizes the number of homes per length of roadway by creating coves of deeper setbacks along the outside of roadway arcs. Coving is much more than curved streets with staggered home fronts. Efficient coving design improves aesthetics dramatically and gives more area to lots, building area, and open space without sacrificing anything but roadway.
Aesthetics
In addition to the natural aesthetics caused by the setback line meandering separately from the roadway, most coved neighborhoods also have a winding walk set in public easement that takes on its own form separate from the curvature of the setback and street lines. Greater open space also affords the amenities available to large parks.
Costs vs. property value
An efficiently coved layout reduces improvement costs because there are less improvements. Coving drastically reduces roadway, thereby lowering surfacing, sewer, water, pressurized irrigation, and gas-line costs for the utilities that run along the roadway. Some of these savings can be added back into the larger park and open area amenities to raise the value of the nearby lots. Individual properties also gain aesthetic value from the separate meandering setback lines, sidewalks, and roadways. The improved cost per square foot or meter of a coved subdivision is accentuated by the greater area of each lot.
