Legal description of Hudson's city boundaries

[Torie]

Just go to google maps, and you can pull up any address that you want. Yes, the townhouses are relatively new, and some recently built. We just approved a variance for the buildout of two more.

Just go to google maps, and you can pull up any address that you want. Yes, the townhouses are relatively new, and some recently built. We just approved a variance for the buildout of two more.

The houses on the south branch are numbered 1-12 going south, and 13-22 coming north?

The houses on the east branch don't have numbers.

The houses on the north branch all have the same house number.

[jimrtex]

Query Number 3



What is the nature of the roadway shown in red on the former railroad bed? Can you drive south on Front Street, and if so, where does Front Street end and the new road begin?

What is the pavement? What happens at 3rd Street, is there a fence?

[jimrtex]

Query Number 4



Does the green line represent an escarpment?

[jimrtex]

Query Number 5 (a, b, c)



This is generally southwest of Allen St and S Third Street.

(a) Is this bright red line a reasonable representation of Deer Alley west of Cross Lane, as opposed to the census version which is the pale red short stub?

(b) Is it correct that South Alley does not exist (the pale red stub extending eastward from the northwest corner of Tanner's Lane.

(c) What streets comprise the yellow line?  Cross Street to the west and Tanners Lane to the southeast, but what is in between.

[jimrtex]

Query Number 6



Is there any reason that (shown in red):

(a) Cherry Alley from City Hall Place to 5th St, in particular both sides of 4th Street, should not be used as a block boundary?

(b) Rope Alley from 6th Street to 7th Street should not be used as a block boundary?

[jimrtex]

Query Number 7



Does Long Alley east of 7th Street reach Columbia Street?

The yellow line represents placement for the 2010 Census , which is clearly wrong. The pink curving line represents a modification made between 2010 and 2015. To me it looks like a fantasy line drawn as a replacement for the yellow line.

[jimrtex]

Hudson Query 8



Does this seem reasonable?

Changes:

(a) Mill Street extended east to match 3rd Street Extended. To  change a feature, it has to be deleted, and then re-added.

(b) Stream (does it have a name?) redrawn from Mill St (east of  2nd Street) to Underhill Pond. The current version veers south toward 3rd Street. Can its location be identified on foot?

(c) Eliminated statistical line which had been drawn from Clinton and Harry Howard to the end of 3rd Street. Sometime in the past someone had tried to lop of the southern part of the Great Northern.

(d) Eliminated fantastic vision of Washington Street drawn through the school and almost reaching 3rd Street, and replaced actual stub west of Short St/Harry Howard.

(e) Added 3rd Street extension north to Mill Street. Can this be traversed on foot? There is a public right of way, and it has been used as a ward boundary for the past 201 years.

(f) Added bicycle path up the Dugway. I removed what is labeled as Mill Street off of Harry Howard. It appears that the bike path extends to Lucille where it leads into the bike path on the west side of Harry Howard. The bike path is paved and has vehicle barriers?

(g) The Clinton Street extension  from west of 5th Street to Harry Howard already exists, as does Underhill Pond. We simply need to mark them as block boundaries. The Clinton Street extension is in the public right-of-way, and can be traversed on foot?

This creates the following blocks:

(1) 2nd Street (and Mill Street), Strawberry Alley, Robinson Street, 3rd Street, 3rd Street (extension), stream, Mill Street.

(2) 3rd Street (extended) and stream, Mill Street, stream.

This block is unpopulated, but I want to establish the stream as a consistent dividing line.

(3) State Street (and 3rd Street), Carroll Street, Short Street, Harry Howard Avenue, stream, 3rd Street (extension), 3rd Street.

This has the bulk of the population.

(4) Lucille Drive (and Harry Howard), Dugway bike path, 3rd Street (extended), stream, Harry Howard Avenue.

The portion along Lucille Drive is quite short, to get from Harry Howard to the bike path. There are a couple of houses on Harry Howard.

(5) Great Northern.  Mill Street (and 2nd Street), Dugway bike path, Lucille Drive, Harry Howard Avenue, city limits, 2nd Street.

The population will consist of the Firemen's Home, the houses north of Mill Street (east of 2nd Street), and the houses on Lucille. The group quarters population of the Firemen's Home will be available, so if the block has to be divided, it will only be to divide the Mill Street population from the Lucille Drive population.

[jimrtex]

Query Number 9



The shorelines of Underhill Pond and Oakdale Pond are already demarcated as linear features. We will seek to have them made census blocks, rather than drawing the streams through the ponds.

The stream locations were guided by topo maps and historical maps. Clearly they have had an impact on development, as they terminated development of the grid northward (it may really be the north facing slope going down into the stream). Glenwood Boulevard is clearly on the high ground between streams. If that land could have been developed in the early 20th Century, it would have.

The definition fritters out on the extreme eastern end, so I chose a convenient connection to the street grid.

There was (is?) a spring near Spring Street, and I just slipped a little bit to connect to the RR tracks.

According to Topo sheets, the deepest drainage of the north branch is a Parkwood and Oakwood. I instead connected to Oakwood so that all the houses on Glenwood were south of the stream. It might be possible to go north of the houses on Paddock Place. I assume that a visible swale is visible on Paddock Place. The terrain is deeper on the east side of Paddock, as if the upper end of a ravine has been filled some.

I eliminated the driveways at the Middle School. I retained what is listed as a footpath, and was used as a block boundary in 2010 (it was not used in 2000) and is barely visible in aerial photos. It may just be an informal shortcut to the school. But we might be able to hold it for 2020.

Footpath's can not be added as linear features. Neither may walkways, but I'll go ahead and try with Warren.

OR the census bureau does permit city parks to be demarcated as areal features, and the boundaries used as block boundaries. The property tax map does show Promenade Hill Park. The walkway is shown as a public right-of-way for the stub. How about including the walkway as a panhandle of Promenade Hill Park?

If we are doing parks we could also do Public Square. Incidentally the parcel of land on the southwest corner of Mill Street and 3rd Street - is given that as the location, and identified as playground. Maybe Clinton and 3rd Street can be identified as streets?

The prospective blocks east of Harry Howard:

(1) Washington Street (and Harry Howard Avenue), N 5th Street, Clinton Street, Clinton Street Extension, Harry Howard Avenue.

This was a census block in 1990.

(2) 6th Street (and Clinton St), stream, south shore of Underhill Pond, stream, Harry Howard, Clinton St (extension), Clinton Street.

This includes the houses on the north side of Clinton, and a couple on the west side of 6th.

(3) Underhill Pond.

It is simpler to treat as separate, rather than choosing one side or the other as a boundary, or drawing a line through the middle.

(4) 6th Street (and stream between Underhill and Oakdale ponds), foot trail to middle school, stream, eastern shore of Underhill Pond.

Unpopulated, potentially could be attached to Underhill Pond. If the foot trail is not a block boundary, then this become the western extension of the block on the north side of Glenwood Blvd.

(5) Harry Howard Avenue (and Lucille Drive), stream, north shore of Underhill Pond, stream, walkway, Paddock Place, Harry Howard Avenue, Rogers Lane, Hoysradt Lane, Edmonds Lane, Harry Howard Avenue.

Crosswind Apartments (outside loop) and houses on south side of Harry Howard and north of Underhill Pond.

(6) Edmonds Lane (and Harry Howard Avenue), Hoysradt Lane, Rogers Lane, and Harry Howard Avenue.

Interior Units of Crosswind Apartments.

(7) Green Street (and State Street), Fairview Avenue, RR Tracks, State Street.

I had thought about restoring the extension of Jenkins Parkway to form a census block, but it would leave the rest of the neighborhood in the large block extending west along Green Street. The population is concentrated in the east end, but Green Street possibly could see apartments developed.
In any case, the RR tracks are a very useful boundary.

(8) Washington Street (and 6th Street), Seventh Street, State Street, RR tracks, stream, south shore of Oakdale Pond, stream, 6th Street.

The dividing line is a bit awkward, but it does separate the residences at the west end on 7th Street and Railroad Avenue from the houses on Glenwood. Their appears to be an area of impoundment (mossy green) by the RR tracks, north of the bend in Green Street. Conceivably the stream from Oakdale Pond could be routed there.

Incidentally, there is a quiet house on 3/4 acres on Railroad Avenue. Unless you knew the people, you probably would not know of its existence. The buildings on 7th Street are residential, but no registered voters on the east side of the street (even addresses). There are 3 registered voters on Railroad Avenue, two at the mentioned house, and one who gave an address of 25 Railroad Avenue, which is the address of the Columbia County Department of Human Services. Either someone who was given an application to vote, and was confused as to what address to use, or possibly homeless.

What is GCT zoning classification?

(9) Glenwood Boulevard (and Fairview Avenue), 6th Street, stream, northern shore of Oakdale Pond, stream, RR tracks, Fairview Avenue.

South side of Glenwood Boulevard and both sides of Spring Street.

(10) Oakdale Pond

(11) Parkwood Boulevard (and Glenwood Boulevard), Oakwood Boulevard, stream, trail, Glenwood Boulevard.

Houses on north side of Glenwood Boulevard and Parkwood Boulevard (the house on Oakwood is north of the stream).

(12) Paddock Place (and Oakwood Boulevard), trail, stream, Oakwood Boulevard.

A few houses on west side of Paddock Place and Oakwood Boulevard.

[jimrtex]

I found a source for the location of streams, the 1940 Census Map.



This indicates the northern branch should cross Paddock Place.

Do you have any thoughts on retaining the footpath north from Glenwood Boulevard and 6th Street to the Middle School. It is hardly visible and may not be open to the general public, because it is on school grounds.

[jimrtex]

The house just north of the Green Line (putative city limits) is in Hudson according to the tax rolls and voter registration rolls, but was probably enumerated in Greenport.

[jimrtex]

The census bureau classifies features (point, linear, and areal) with a MAF/Tiger Feature Classification Code (MTFCC). This is a 5-character code. The first letter indicates a type of feature (eg 'S' for streets), and the last four numbers a subtype. For example:

S1100 primary road
S1200 secondary road
S1400 neighborhood street

'P' features, are primarily "Nonvisible Legal/Statistical Boundary", with a typical use of marking a block boundary. In some instances, the lines had been recognized as streets or roads, and used to define block boundaries. The census bureau has determined that the road does not exist, but has converted to a statistical line in case there is a desire to maintain a block boundary.

I have flagged the lines in red on the map above for deletion:

(1) Roads in the cemetery were badly aligned for the 2010 Census, and were used to define census blocks. The census bureau has downgraded the streets to statistical lines. Since there is nobody living in the cemetery, there is no point in maintaining them.

(2) Former open reservoirs on Reservoir Hill replaced by closed storage.

(3) Spurious line southeast of Warren-Worth intersection.

(4) Spurious extension of Joe Alley.

(5) Spurious duplication of State Street between railroad tracks and Green Street.

(6) Residual from realignment of Long Alley into Columbia Street.

(7) Non-existent Prison Alley across Public Square.

(8) Connection of Hudson Avenue to RR tracks, ineligible for use as block boundary.

(9) Residual from realignment of Power Avenue to spike along 3rd Street.

(10) Spurious possible duplication of road on former rail bed east of 3rd Street at southern city limits.

(11) Line apparently to connect Clinton St and Harry Howard to north end of 3rd Street.

(12) Lines in North Bay (lines defining Census Tracts 12 and 13 retained).

[jimrtex]

'P' Linear Features to Be Retained.



'P' features are non-visible statistical or legal boundaries, including boundaries of areal features including water features.

The following lines are to be retained:

(1) Water Boundaries.

(A) Hudson River shoreline.
(B) Open water in North Bay.
(C) Residual of South Bay, west of 3rd Street.
(D) Underhill Pond.
(E) Oakdale Pond.

(2) Limits of Areal Features.

(A) Hudson Correctional Institution. Census 2020 intends to enumerate prisons and similar facilities (eg Universities and Colleges) as separate census blocks. It might be better to show the boundary of the prison property that extends from 3rd Street to Worth Avenue. This would make the non-prison areas on Union Street and Worth Avenue a clearly separate block.
(B) Western limit of Columbia Memorial Hospital.
(C) Limits of Cedar Park Cemetery. It might be better to eliminate the northern and eastern bounds, and use Columbia Turnpike and Newman Road as the cemetery limits.

(3) Statistical boundaries.

(A) Non-visible Hudson City limits, including city/county boundary in Hudson River. Boundaries along Ten Broeck Lane, Newman Road, Columbia Turnpike, Paul Avenue, Union Turnpike, Graham Avenue, and Fairview Avenue use those streets. The gap in the southern boundary is marked by a property parcel line.
(B) Lines from Front Street and Dock Street, northward, and then westward through North Bay to the center of the Hudson River. This marks the boundary betweens Census Tracts 12 and 13, and is maintained for statistical continuity.
(C) Extension of Clinton Street from the west terminous of Clinton Street, west of 5th Street to Harry Howard Avenue. This extension is within the Clinton Street right-of-way. It will be used to mark a census block bounded by Washington Street (and Harry Howard Avenue), 5th Street, Clinton Street, Clinton Street extension, and Harry Howard Avenue. This block was enumerated separately in the 1990 census.

(4) Erroneous line reclassified.

(A) There is an inexplicable 10 foot gap in the west track of the railroad mainline, about 120 feet south of Ferry Street. It has been reclassified as a Railroad Feature. It is marked in Orange on the map.

[jimrtex]

New P-Line Features.



These non-visible lines are used to demarcate census blocks. While non-visible, their location is easily discernible on the ground.

(1) 3rd Street Extension, from end of 3rd Street, north of Robinson Street to Mill Street. The extension is in the 3rd Street right-of-way. This has formed part of the ward boundaries of Hudson since 1815.

(2) Limits of Promenade Hill Park. The eastern limit is Front Street, and the western limit, the escarpment. Promenade Hill Park is the oldest public park in the United States, dating from 1795.

(3) Ferry St. Extension from end of Ferry Street to Hudson River. Permits use of Ferry Street to Hudson River.

[jimrtex]

Hudson Natural Features.



While block boundaries are typically streets and roads, visible natural features such as streams may also be used. The census bureau is primarily interested in visible features since this permits more accurate placement of residences, so that people are counted in the right place.

Smaller streams are represented by lines. Rivers and lakes may be represented as areal features. It is their shorelines which are represented by lines.

(1) Existing streams to be retained (green on map)

(A) Stream in  South Bay.
(B) Portion of North Bay immediately east of railroad tracks. This is about 60 feet wide at its southern mouth, but is represented as a line.
(C) Stream from North Bay to about Mill Street and 2nd Street. This is the stream that flows through Underhill and Oakdale ponds. The actual course might be better refined.

(2) Stream to be deleted (red)

(A) Stream from 2nd and Mill Street. Poorly aligned and spuriously connects to 3rd Street.

(3) Streams to be added (cyan)

This is the stream to the north of the developed central plateau of Hudson, and essentially marks the northern limit of the street grid.

(A) 2nd and Mill Street to Underhill Pond.
(B) Underhill Pond to Oakdale Pond.
(C) Oakdale Pond to Power Springs (connects to RR tracks near end of Spring Street.
(D) Underhill Pond to Paddock Place (connects north of houses on Paddock Place.

(4) Escarpment added (purple)

(A) Escarpment between Ferry Street and Dock Street on west edge of Promenade Hill Park and Hudson Terrace apartments. 50 to 75 feet above Hudson River.

[Torie]

Many of the features you use are not depicted on the census block map, nor appear on google map aerials. So how can they be used?

[jimrtex]

Deleted Streets



Linear street features were deleted for several reasons:

(1) They do not exist.
(2) Badly aligned. The location in the census bureau database does not match the location on the ground. To add the correct location, the old location is deleted, and replaced by the new location.
(3) Extend or truncate streets. The location in the census bureau database does not include the full length of the street. To add the correct length, the current location is deleted, and replaced by the now location.
(4) The street is a driveway or internal road, not intended for general traffic.

(1) They do not exist.
(A) Spurious extension of Faxon Avenue, northwest of Fairview Avenue and Storm Avenue.
(B) Spurious branch of Columbia Turnpike, just east of Prospect Avenue-Columbia Street intersection.
(C) Road west of Columbia Memorial Hospital, between Prospect Avenue and Columbia Street.
(D) Two spurious roads in block bounded by State Street and Long Alley; 6th Street and 7th Street.
(E) Spurious street in block bounded by State Street and Washington Street; 6th Street and 7th Street (not to be confused with Rope Alley).
(F) South Alley (northwest end of Tanners Lane)
(G) West of RR tracks, north of Ferry (former Partition Street)
(H) West of Front Street at Warren.
(I) State Street west of Front Street.
(G,H, and I predate development of Hudson Terrace when E-W streets extended west of Front Street. These are residual, which somebody decided must be there for some reason.
(J) Front Street, north of Dock Street.
(K) Mill Street, west of Lucille Drive (and Harry Howard). Replaced by bike trail.

(2) Badly misaligned road (current census alignment deleted)
(A) Van Winkle Road, Van Winkle Road Ext, and Academy Hill Drive do not match current buildout.
(B) Deer Alley, west of Cross Lane (census shows as stub)
(C) Washington Street west of Harry Howard Avenue (fictional version).


(3) Street to be extended or truncated (current census version deleted)
(A) Hudson Avenue, replaced by truncated version.
(B) Cherry Alley, between City Hall Place and 5th Street, the central section across 4th Street is inexplicably missing.
(C) Ferry Street to be truncated through marina parking lot.
(D) Dock Street west of Front Street, to be extended further west.
(E) Mill Street east of 2nd Street to be extended to 3rd Street, and Dugway bike trail.

(4) Driveway.
(A) Driveway at roughly 900 Columbia Street northward. Badly placed on census map.
(B) Driveway to Bronson House on HCI grounds. Badly placed on census map.
(C) Roadways in Hudson Correction Institution. They are badly misplaced. A single route through the prison from East Court Place past the main parking lot, and to the road east to Worth Avenue is retained.
(D) Lombard Street (south of Dock Street)
(E) Driveways at Middle School off Paddock Place
(F) Driveways at FASNY Firemen's Home off Harry Howard
(G) Driveways at High School off Harry Howard

[jimrtex]

Added streets.



These are of two types:

(1) Corrections to existing streets. In the case of corrections, the old street was deleted.
(2) New streets.

(1) Corrections to existing streets.
(A) Corrected alignment of Van Winkle Road, Van Winkle Road Extension, Academy Hill Drive.
(B) Continuous single public access route through Hudson Correction Institution.
(C) Extend Ferry Street towards water, eliminating parking lot.
(D) Correct alignment of Deer Alley west of cross lane.
(E) Completion of Cherry Alley between City Hall Place and 5th Street (missing gap)
(F) Truncate Hudson Avenue to actual street.
(G) Corrected Washington Street west of Harry Howard Avenue (actual location)
(H) Dock Street west of 2nd Street, extended further west.
(I) Mill Street east of 2nd Street, extended east to 3rd Street.

(2) New Streets.
(A) South Bay Causeway Truck Route (replaces RR tracks)
(B) Rope Alley between 6th Street and 7th Street
(C) Bike path up Dugway between Mill Street (and 3rd Street) to Lucille Drive (near Harry Howard), replaces Mill Street at east end.

[jimrtex]

Changes to railroads



Existing tracks are in green (both tracks on north/south mainline are depicted in census data base.

A small gap (10 feet) in the west track south of Ferry Street has been corrected (shown in orange, but not really visible at this scale).

Tracks that have been removed are in red.

(A) To cement plant across South Bay causeway (replaced by truck route)
(B) Siding east of East Court Lane.

It is intent to use the east-west tracks between Front Street and Union Street; and State Street and Fairview Avenue as block boundaries. This will provide a clear limit to most of the developed area on the south side of the city, and a separation between Green Street and Glenwood Boulevard. This was done in 2000, but removed in 2010.

Between Union Street and State Street, the tracks will not be used since this simply causes senseless division of small areas.

[jimrtex]

Hudson Proposed 2020 Edges



The census bureau maintains a database of edges (polylines). Edges have a location (a series of Latitude/Longitude points), and thus have a direction, from the starting point to an ending point.

Edges do not cross. So for example at the intersection of 3rd and State Street there are 4 edges that meet, corresponding to (1) State Street from 3rd to 2nd; (2) State Street from 3rd to 4th; (3) 3rd Street from State Street to Rope Alley; (4) and 3rd Street from State Street to Long Alley. (the order I've used here may not reflect the order in the database, but was just to illustrate the four edges going away from the intersection.

Edges do not not have to join other edges at their endpoints. For example, Rope Alley east of 3rd Street only connects on one end. The edge defining the shoreline of Underhill Pond connects with it self (a common start and end point).

A closed path of edges define a face. Some faces are census blocks. A census block must be defined by a closed path of edges, so it could be comprised of adjacent faces (share one or more edges).

The Census Bureau may have to split edges to reflect new edges. In other cases it may join edges that are connected end to end.

For example, the Census Bureau inexplicably does not believe that Cherry Alley is continuous from City Hall Place to 5th Street. Instead it had used statistical lines to close the gap across 4th Street. For the 2010 census the statistical lines were not used, and if you look at census block map, the two blocks on either side of 4th Street go from Warren Street to Union Street.

Since the Census Bureau decided those statistical lines did not correspond to anything, it removed them. This meant that the two edges corresponding to 4th Street could be merged (they connected end to end, and had other shared characteristics, such as a the same name). This can be an automated process. They gave a new TLID (permanent edge ID to the merged edge). TLID's never change, so the old TLID's were retired. TLID's are now around 700,000,000 for the USA.

Since I am now reinserting Cherry Alley, it will re-split the edge on 4th Street, likely resulting in creation  of two new edges.

Edges have two faces associated with them, one to the left and one to the right. For example, the edge corresponding to your block is to left of Robinson street, to the left of Rope Alley, to the right of 2nd Street, and to the left of 3rd Street. From this we can see that the numbered streets were drawn south to north, while Rope Alley was west to east, and Robinson from east to west. In most likelihood, the east west streets were digitized from Front Street to whereever they end, and the numbered streets from south to north, and then they let a computer slice them into edges.

Faces may have holes in them. For example, the face that envelopes Underhill Pond has 19 edges associated with it. Since the Clinton Street extension is part of the census data base, it is one of the edges that define the face. The pseudo-block bounded by Harry Howard, Washington, 6th Street, Clinton St, and the Clinton extension is a separate face.

The census block is comprised of three faces: the one from Clinton to Harry Howard and Paddock Place, Underhill Pond, and the pseudo-block.

We will "suggest" to the Census Bureau that they use the Clinton Street extension as a block boundary, so that the block between Washington and Clinton (extended) and Harry Howard and 5th Street will be a census block.

For each edge, there are the following fields (in a spreadsheet each row corresponds to the record for an edge, and each column corresponds to a field).

STATEFP (36 for New York)
COUNTYFP (021 for Columbia)
TLID (Permanent Edge ID)
TFIDL (Permanent Face ID, Left)
TFIDR (Permanent Face ID, Right)
MTFCC (MAF/Tiger Feature Classification Code)  For example a neighborhood street is S1400, a stream H3010.
FIDELITY (flag indicating location has been enhanced, be census bureau)
FULLNAME Name of feature (eg Robinson St)
SMID (Spatial metafile ID) I don't know what this is.
BBSPFLG (Block Boundary suggestion from 2010, Must Hold, Don't Hold)
CBBFLG (Planned 2020 block boundary)
BBSP_2020 (suggested block boundary)

So CBBFLG says what the census bureau plans to do, and BBSP_2020 is our suggestion. The census bureau plans to use Robinson Street (from 2nd Street to Strawberry Lane). We could suggest that it not be used.

CHG_TYPE= "DL" delete line, "AL" Add line, "CA" Change attributes.

When I wanted to delete a line, I changed the field to "DL".

When I wanted to add a line, I created a new feature, which saved its location (vertices of polyline) and created a new row, I then edited the row. I would insert the MTFCC, the name, and added "AL".
If the new line was replacing an existing line, I would duplicate the TLID, and make the changes.

If I were just changing attributes, the field is "CA". For example, "Van Winkle Rd" was mispelled as "Vanwinkle Rd", which I correct. I also corrected the 10-foot gap in the RR which was miscoded.

JUSTIFY 150 characters of justification for the change. I entered something for every change. I don't know if it is required, but it would help me remember why.

These are the house numbers on the left and right side of the street. For Robinson they are:

Left: 249-201
Right: 298-200

Because the edge for Robinsion is directed from east to west, left is as you walk from 3rd Street. There is a an assumption that street numbers are odd and even on opposite sides of the street (this is likely USPS policy). And the ranges are potential.

Because Strawberry Lane intersections Robinson Street, there is a second edge for the portion of Robinson Street south of the form Charles Williams School. Its address ranges are:

Left: 299-251
Right: NULL-NULL.

So we can expect that numbers higher than 251 are opposite the school.

ZIPL Zip code to the left
ZIPR Zip code to the right

In the map above, the edges are color coded by type:

Yellow: Streets, bike paths, foot paths
Red: Statistical/legal lines.
Purple: Landmark boundaries.
Green: Railroads.
Cyan: Water

Prospective 2020 Census Blocks



Areas in greenish have no change from 2010.

Areas in blueish are expansions of current blocks due to elimination of mostly non-existent features, this will have negligible effect since most of the eliminated blocks had 0 population.

Areas in orangeish are divisions/revisions of current blocks due to:

(1) Using railroads as block boundary between Union Street and Front Street; and State Street and Fairview Avenue.
(2) Separation of Hudson Correction Institution as a block.
(3) Elimination of railroad across South Bay. While I delineated the South Bay Causeway Truck Route, it would not be held as a block boundary.
(4) Addition of Promenade Hill Park.
(5) Delineating Cherry Alley between City Hall Place and 5th Street.
(6) Delineating Rope Alley between 6th Street and 7th Street.
(7) Adding Stream 201a from North Bay to near eastern boundary.
(8) Using Underhill and Oakdale ponds as block boundaries.
(9) Extending Mill Street to 3rd Street (extended).
(10) Adding Dugway bike route.
(11) Adding 3rd Street extension from north of Robinson Street to Mill Street.
(12) Utilizing Clinton Street extension from west of 5th Street to Harry Howard Avenue.

[jimrtex]

This is an alternate version.



This eliminates the goat trail from 6th Street and Glenwood Avenue, and uses the northern shore of Underhill and Oakdale ponds as the block boundary. This would eliminate 4 unpopulated blocks.

The other change would be to place North Bay into a single unpopulated block.

Nothing connects from Mill Street to Harry Howard, and yet you drew lines between the two - twice.

I added the lines.

We start with the 2010 lines (2015 actually).

The first part of the Block Boundary Suggestion Project is to propose edits to the current lines.

The census bureau is primarily interested in areas that have been newly developed, or redeveloped, since that is where there will be new streets, or changed streets. The census bureau is mainly interested in associating street addresses with census blocks, so that they can get people placed in the right area.

Second is to eliminate errata. Features that no longer exist (or never existed) or are missing or badly placed.

The third part is to suggest which lines be used as block boundaries.

I am being slightly aggressive in the second part, knowing where I will want to suggest blocks be place.

Mill Street clearly exists to 3rd Street. To change a feature, the old version is deleted, and a new one is added. So what I am really doing is telling the census bureau that their current line for Mill Street is too short.

The bike trail up the Dugway does exist, and what is shown as Mill Street at the top end does not exist. So I am telling the census bureau to eliminate that part of Mill Street and add the bike trail.

Mill Street and the bike trail are visible. Someone who lives in Hudson could verify their existence.

2020 Census Program Phases

PL 94-171

We are implementing PL 94-171, which requires the Census Bureau to consult with bodies responsible for redistricting as to what areas to enumerate. It is reasonable to assume that New York state wants a single set of data to be used for congressional, legislative, and local redistricting, even though it is unlikely that Hudson will be divided by legislative or congressional districts.
