I have my answer. Battery Park City recently entered into a lease agreement with the Poulakakos Family, which operates a number of restaurants in Downtown Manhattan. Pier A will soon feature an oyster bar, a visitor center, a promenade around the pier and an upscale restaurant on the second floor.

Here’s a picture I took earlier this year of Pier A from a New York Waterway ferry boat (click for larger image):

Pier A - Downtown Manhattan Waterfront

Pier A was built in 1886 for the Department of Docks and Ferries as well as for the Harbor Police. The clock tower, added in 1919, was the first World War I memorial. During my walking tour of Downtown Manhattan starting this coming Saturday, I will share the history of Pier A and explain how the clock, which rings ship’s time, operated.

High Bridge Mountain Bike Course

(Highbridge Park is also home to the High Bridge and High Bridge Tower, part of the Croton Aqueduct system. Last year I blogged about the High Bridge and High Bridge Tower, and took pictures of the New York City portion and New York State portion of the Croton Aqueduct trail.)

Here is a map that shows the location of the Highbridge mountain bike trail. The green pin shows the entrance to the trail at Dyckman Street and Fort George Hill Road. The bike icon shows the general location of the trail:

New York City Department of Parks and Recreation collaborated with the New York City Mountain Bike Association to develop these cross-country and free-ride bike trails as well as the dirt jump/BMX trails. There are bike trails for beginner, intermediate and expert riders.

On the NYC Mountain Bike Association website, you can learn more about the Highbridge Park bike trails and dirt-jump park. And view a detailed trail map (PDF) of the trails:

Highbridge Park Mountain Bike Trails map

Yonathan Arava produced and directed an excellent documentary about the planning and building of the Highbridge Park mountain bike trails. You can watch this video on Vimeo.

I often stop at this park when I’m biking along the Manhattan waterfront. The excursion boat pier and kayak launch should be open this spring or summer.

View the following slideshow or visit my West Harlem Piers Park photo set on Flickr:

I would like to know about the construction of the bulkhead at West Harlem Piers Park. I’m especially interested to learn about the white material connected to the bulkhead where it intersects with the Hudson River. Do you know what it is for?

Vision 2020 is a 10-year plan for the future of NYC’s 520 miles of waterfront and represents the culmination of a one-year participatory planning process. The New York City Waterfront Action Agenda outlines 130 waterfront projects that will be initiated in the next three years.

Urban Ranger Jerry Seigler leading geology tour of Inwood Hill Park

The tour started inside the Nature Center, which is right along the only natural salt water marsh in Manhattan:

Nature Center and Salt Water Marsh and Inwood Hill Park

The Nature Center includes exhibits about local rock formations, salt water marshes and other natural features of Inwood Hill Park. The following picture is of Inwood Marble, which is the softest of the three rock layers on which Manhattan rests. You can identify Inwood Marble by its sugar-like crystals and its white or blue-grey color:

I took this close-up shot of Inwood Marble outcroppings in Isham Park, which is just southeast of Inwood Hill Park:

A picture of Fordham Gneiss in the exhibit at the Nature Center. Gneiss consists of alternating light and colored bands and is the deepest and hardest of the three primary metamorphic rocks that form Manhattan and the surrounding areas:

The Columbia “C” painted on a Fordham Gneiss outcropping in the Bronx, directly across from Inwood Hill Park’s Nature Center. Because of pollution and erosion, it is difficult to see the alternating light and colored bands of the Gneiss:

A picture of Manhattan Schist in the exhibit at Inwood Hill Park Nature Center. Manhattan Schist is the island’s strong bedrock on which skyscrapers are built downtown and in midtown. Almost all of the rocks in Inwood Hill Park are Manhattan Schist. Schist often contains mica specs, a flaky mineral that appears metal-like:

During the the last ice age, the Wisconsin Ice Sheet reached a height of 1,000 feet, crushing the lands and forming valleys and riverbeds. The advancing and retreating ice sheets also left their marks with glacial scratches or striations that you can sometimes see in exposed rocks. Urban Park Ranger Jerry Seigler showed us an example of glacial striations on what is known as “whale rock.” These large groves run in a north south direction, following the path of the ice sheets:

Glacial striations on Whale Rock in Inwood Hill Park

This is a close-up of a glacial striation on Whale Rock:

As ice sheets advanced and retreated, they often dislodged rocks from one location and moved them to another location. This picture, from the exhibit, is an example of the many rocks from the Palisades, across the Hudson in New Jersey, that were moved to Inwood Hill Park. Rocks that are moved by glaciers are called erratics:

On the Clove Trail that runs through the heart of Inwood Hill Park, there are glacial potholes that were formed as the melting water from an ice sheet mixed with gravel and rock to drill down into the below rock formations. And the result is this glacial pothole:

On the Clove Trail, you will also come across a number of caves known as the Indian Rock Shelters, which were occupied for centuries by the Lenape. Here’s one of them:

Pier 25 includes a 19-hole miniature golf course, beach volleyball courts, an artificial-turf playing field, a boat mooring, berths for historic ships, a playground, a snack bar and lounge chairs to take in the great views of the Hudson River, Battery Park City and Jersey City:

Map of Spuyten Duyvil Creek and Surrounding Neighborhoods

I created an annotated Google Map with placemarkers and lines that you can click on to learn about Spuyten Duyvil Creek and the Harlem River Ship Canal as well as neighborhoods, historic sites, parks, bridges and other features of interest. You can click on the placemarkers in the map immediately below or view this map on Google. (I recommend that you view this map on Google–it’s easier to explore and navigate):

Slideshow of Spuyten Duyvil Creek and Neighborhoods

Last Saturday, I walked through Inwood Hill Park, over the Henry Hudson Bridge, through the Spuyten Duyvil and Marble Hill neighborhoods in the Bronx and over the Broadway Bridge into Manhattan. The following slideshow includes pictures of this walk and I have added images that I took of this area last summer. You can view this gallery with captions on Google Picasa:

You can view these geo-tagged photos on a Google Map so that you can see the exact location of where I shot each image:

In this post, I’ve included maps that offer different ways to see the locations of CSO outfalls in New York City.

NYC Green Infrastructure Plan

The NYC Green Infrastructure Plan, released in September 2010, outlines the city’s new approach to improving water quality by cleaning up the city’s rivers, creeks and coastal waters. An important component of this plan is investment in stormwater controls that will help reduce the amount of untreated sewage released through CSO outfalls. On page 16 of this plan, you can view the location of CSOs. The Tier 1 CSOs, marked in red, release the highest amount of untreated sewage into NYC’s waterways:

NYC Green Infrustructure Plan - CSO Outfalls

NYC OASIS Map

The Open Accessible Space Information System (OASIS) is an interactive map that displays data about New York City’s transportation, environment, parks, land use and population. The CUNY Mapping Service at the Center for Urban Research manages this large-scale mapping project, now in its tenth year, with the support of its many data partners.

In the right-hand legend of the OASIS map, you can activate the “Combined Sewer Outfalls” option within the “Environmental Impact/Cleanup” layer. The location of all CSO outfalls are displayed as on the following screen shot (direct link to OASIS map displaying outfalls):

OASIS Map - Combined Sewer Overflow Outfalls in New York City

Then you can zoom-in to a specific CSO outfall and click the map to view a satellite image of the surrounding area. You can click the “N”, “E”, “S” and “W” letters at the top left of the resulting image to rotate your point of view so you can see the outfall:

OASIS - Aerial Photo of Combined Sewer Overflow in the Bronx

In a 2009 post on Urban Omnibus, Steven Romalewski, director of CUNY Mapping Service, shares the history of OASIS and includes information about the combined sewer overflow layer.

HabitatMap and Stormwater Infrastructure Matters

HabitatMap is a community-based, map-making initiative designed to show the impact of the built environment on human health. Anybody can create a map, place markers to highlight sites of interest and add multimedia content to each location.

Michael Heimbinder, founder of HabitatMap, collaborated with the S.W.I.M coalition (Stormwater Infrastructure Matters) to create the Where Does My Toilet Flush To? map. This map focuses on the location of the Tier 1 CSO outfalls and the disproportionate amount of sewage they release. In the following screen shot of this map, the green flags represent the location of Tier 1 outfalls and the orange flags represent the location of sewage treatment plants. When you visit this map, click on the green flags for detailed information about the amount of sewage released at each location:

You can learn more about the “Where Does My Toilet Flush To?” map on the S.W.I.M. site.

On HabitatMap, you can view additional maps that highlight environmental and sustainability issues including: Barge NYC’s Garbage and Newton Creek Green Infrastructure (scroll down page for map).
