Roads and Parks Round out Soup-to-Nuts
Building the West Side's Riverside South residential development
has involved a big infrastructure workload. Upon its eventual
completion, the work on infrastructure and parkland construction
at the site between 59th and 72nd streets will cost roughly
As New York-based Bovis Lend Lease and HRH Construction each
build the residential high-rises, they are also constructing
the roadways that serve the new towers, as well as building
parks, and burying sanitary sewers, storm drains, gas and
telephone lines, and water mains. The work requires extensive
coordination with New York City's departments of transportation,
parks, and environmental protection.
"They are extending the roadway with every building
that goes up," said Alan Dzbanek of Hudson Waterfront
Associates, the developer. Dzbanek, who left Hudson Waterfront
in June, added that Bovis has handled most of the work.
The roadway work calls for construction of two new streets
that run north and south on the 74.6-acre site: Riverside
Boulevard from 59th to 71st streets along the western edge
of the development; and Freedom Place South, which is located
one block east and will stretch from 61st to 64th streets.
The team is also building the east-west numbered cross streets
that connect to the new north-south roads.
So far, Riverside Boulevard is complete from 71st to 65th
streets as the development builds out, largely from north
to south. The teams also completed new sections to each cross
street. The cross streets from 64th to 60th streets are up
The existing portion of Riverside Boulevard actually sits
on a 300-ft.-long relieving platform that the project teams
have constructed in front of each building. The platform,
a 230-ft.- wide and 3-ft.-thick concrete mat, compensates
for weak topsoil by sitting on piles driven into the Manhattan
"The relieving platform sits on about 1,000 piles,"
said Ray Totillo, project manager for Bovis. "It serves
as a surface for subgrade because of the geology there, close
to the river."
Totillo said crews are installing 24-in. sanitary sewer pipe,
18-in. stormdrain pipes, and 6-in. water mains into the roadbed.
They are also installing streetlights, fire hydrants, and
other infrastructure. The utilities so far have gone into
30 to 40 ft. of compacted earth placed on top of the platform
as support for the roadbed, though future portions of Riverside
Blvd. are expected to instead have a tunnel that will allow
eventual relocation of the elevated DiMaggio Highway.
The project also entails the construction of six, one-span
bridges on the new cross streets in order to allow them to
pass over the active Amtrak rails that run through the site
between the development and West End Avenue. The bridges will
be located at every other street from 62nd to 72nd streets.
Bovis is also constructing the 21.5-acre waterside park between
the development and the Hudson River. The job is about halfway
complete, with some parts already open to the public as construction
The $62 million Riverside Park South will eventually stretch
from 59th to 72nd streets. New York-based landscape architect
Thomas Balsley Associates designed the park on the site of
a former railroad yard.
"This is a new park for the 21st Century with a deep
respect for [the site's] past," said Thomas Balsley,
the principal designer. "The park offers a diverse shoreline
The park's design integrates ramps, piers, a rusted gantry,
and other leftover features from the railroad yard. Bovis
is on phase three of a seven-phase schedule. It has completed
11 acres valued at $19.5 million, with a completion of the
four-acre third phase targeted for later this year.
Balsley said the early phases involved constructing shade
structures, wooden walkways, terraces and plazas with seating,
a playground, and a 750 ft. pier jutting out into the river
that is built atop an old wooden shipping pier. Native flora,
such as marsh grasses, are planted throughout the park.
Later phases of work will add new east-west access points,
shade structures, plazas, a shoreline esplanade on the southern
side, courts for basketball and other sports, children's playgrounds,
community gardens, and outdoor concession areas. The city
will own the park, but the building owners will be responsible
for maintaining it.
