1. SUMMARY 1.1 Overview. In response to the nation's need to apply best efforts to Reverse Climate Change by
reducing carbon footprint, this parcel level Relative WALK/TRANSIT Potential (RWTP) data model is being tested and initially deployed at a national level. The goal is to mount a national cadastre map on the Federal Geographic Data Committee (FGDC) sponsored GEOPLATFORM.gov displaying two new thematics, one being 1 ‐ 5 relative WALK and the other being NEAR, VERY NEAR and NOT NEAR Transit, starting with a few counties to test assumptions and automate geospatial processing operations. Scope includes a PHASE I proof of concept mounting of 990 counties, 60M parcels, RWTP expansion and maintenance, though mentioned is not in scope.
1.2 Relative WALK/TRANSIT Potential Description. RWTP is not intended to be used as guidelines, policy or any form of directive. Instead, these layers display spatial patterns of the relative proximity of each parcel on the screen to bus stops and amenities. With the only metric being 1/2 mile distance, universally perceived the same way by just about anyone, RWTP is composed of two nationally consistent, "irrefutable" patterns best directs growth to locations that best expedite transit‐oriented highly walkable development that best reduces automobile dependency and associated carbon footprint (see Figure 1 below). In its initial embodiment, RWTP is therefore limited to just producing spatial patterns (i.e. Relative WALK Potential indicator, with ratings from 1 to 5) rather than 'explicit values' (i.e. WALK SCORE ratings from 1‐99). The target audience is the land investment and development community interested in being up on the most current resettlement trends to maximize their profits as well as households who want to locate in transit centric, highly walkable areas.
FIGURE 1 The Two RWTP Layers as they will appear in GEOPLATFORM.gov
1.3 RWTP Coverage. There are 3,132 counties in the USA with about 135 million parcels. Most are Open Records with acquisition fees of <$200 per year. All of these together can be refreshed for ~$250K/year. Unfortunately, some 600 counties are Closed Records, charging >$200/year. Keeping these counties current would add a prohibitively high $2M/Year to RWTP operations. Therefore, they are to not be included at the offset. Closed Record counties not included on the first day will be added as their data acquisition fees are reset to <$200. Table 1 is a SUMMARY breakdown of US counties according to these categories:
1.3.1 Open Records Complete ‐ All content readily available 1.3.2 Open Records Incomplete ‐ Use Code, valuation, owner info and/or boundary data to be added. 1.3.3 Closed Record ‐ Counties charging greater than $200 for their digital parcel maps 1.3.4 No Map ‐ A parcel boundary map of this county does not exist yet.

1.4 Department of the Interior Request for RWTP to be mounted on GEOPLATFORM.gov. Below is an
email from the US Geospatial Information Officer requesting RWTP be added to GEOPLATFOM.gov. An FGDC resource, GeoPlatform.gov provides shared and trusted geospatial data, services, and applications for use by the public and by government agencies and partners to meet their mission needs. The concerns raised in this email are adequately addressed within this proposal.

1.6 RWTP Benefits.
1.6.1 Benefits to HUD. Since the RWTP design intentionally mirrors the intent of the HUD, EPA, DOT Sustainable Communities Partnership Six Livability Principles, all benefits are described here are the parlance of these Principle. Exact language of pertinent HUD Policies and Programs is excerpted below and shown in FIGURE 6 RWTP advances the Six Livability Principles to expedite Transit Oriented, Highly Walkable Communities that minimize car use and carbon production.
HUD Priorities Affordable rental housing. Providing housing assistance for low‐ and moderate‐income families in the rental market is central to HUD’s mission. HUD is interested in research that improves the efficiency and effectiveness of housing programs, which include public housing, Housing Choice Vouchers, assisted multifamily programs, and FHA insurance. Priority research questions address (among other topics): (a) improving program operations and responses to changing market conditions;
Sustainable and inclusive communities. HUD’s goal of advancing sustainable and inclusive communities seeks innovative and transformational evidence‐based approaches to deal with long‐standing and emerging community development challenges. HUD is interested in research questions such as, but not limited to: (b) understanding and addressing persistent segregation along racial, ethnic and economic lines, and the role of mixed‐income housing and inclusionary zoning in strengthening communities; (c) strengthening urban resilience in the face of climate change, disasters, pestilence and energy shocks; (d) improving integrated and regional planning for land use and transportation;
HUD Roadmap Priorities that align with the four programmatic goals established in the Department’s 2010–2015 Strategic Plan (HUD, 2010: 11): • Goal 1: Strengthen the nation’s housing market to bolster economy and protect consumers. • Goal 2: Meet quality affordable rental homes needs. • Goal 3: Improving quality of life by using housing as a platform.
• Goal 4: Build inclusive and sustainable communities free from discrimination.

HUD Geographic Information Systems Enterprise Portal houses a series of mapping tools and resource leveraged by the addition of a Bus Stop Layer along with the WALK and TRANSIT metrics.
Strong Cities Program. The Strong Cities, Strong Communities Initiative (SC2) ... works to improve the way the federal government engages with and supports local communities to build local capacity to implement their economic development plans to achieve local goals.
Neighborhood Stabilization Program. RWTP support similar to Strong Cities Choice Neighborhoods Mapping Tool. RWTP support similar to Strong Cities
Location Affordability Portal. RWTP support similar to Strong Cities. Choice Neighborhoods is well served by RWTP for identifying priorities for replacing distressed public and assisted housing with high‐quality mixed‐income housing. PolicyMap. This 3rd Party resource to HUD supports the above programs. As such, it is also served by RWTP data including a long desired Bus Stop layer, at no charge. Since the Relative WALK and TRANSIT Potential layers from the RWTP will be in the public domain, parcel boundaries with the two geocodes values could be added to PolicyMap operations at no additional change.
1.6.2 How RWTP advances each of the Six Livability Principles.
1. Provide more transportation choices. Promoting transit use and shows development patterns that would maximize viability of walking and cycling Including the Bus Stop Layer for better assessing Transit Oriented development.
2. Promote equitable, affordable housing. Showing the best areas for locating housing offering minimum dependence on auto use not only encourage workforce housing but better assures it is located in where new workforce residents reduce commute trip and seeking retail services nearby causes the return of basic retail.
3. Enhance economic competitiveness. Eliminating grid lock, greatly reducing VMT enables investments other than creating carbon.
4. Support existing communities. Leverage amenities to guide Transit‐oriented, highly walkable dev. Inc. Bus Stop Layer
5. Coordinate policies and leverage investment. No Relationship 6. Value communities and neighborhoods. Directs Investment to thriving areas for healthy, safe,
and walkable neighborhoods FIGURE 6
SUMMARY of RWTP Benefits of HUD, DOT, EPA and Enterprise GIS
1.5.2 RWTP Benefits to NGAC. Loading RWTP on GEOPLATFORM.gov shall benefit GEOPLATFORM.gov three ways:
1. Expediting Sustainable Communities planning and implementation principles provides clear evidence that the federal government is committed to Climate Change Reversal
2. Makes GEOPLATFORM.gov a commodity resource. As the outreach program (Section 1.3) recruits the dozen top development professional societies (ULI, APA, NACO,...) to promote the RWTP Model, many come to see GEOPLATFORM.gov as first‐choice geospatial informational resource hub for making location and investment decisions that best contribute to Carbon Footprint Reduction.
3. Initiates the National Cadastral Layer, mandatory, elusive, Circular A‐16 Seventh NSDI Framework Theme

2. RWTP SPONSORING ORGANIZATION To be Identified, preferably US DOT. RWTP Data Sponsor Program Management Responsibilities include: 2.1 RWTP Development Management. To Provide: ‐ Oversight in the final design and initial building of the data model ‐ Quality Assurance in accepting the completeness and competency of the two layers. ‐ Upon acceptance, pass the content on to GEOPLATFORM.gov for loading.
‐ Quality Assurance includes spot checking for competency of GEOPLATFORM.gov ‐ Oversight in Open Records Incentive Outreach Program. 2.2 RWTP Ongoing Maintenance, Updating and Expansion. ‐ Review and acceptance of each quarterly submission of additional/updated content. ‐ Upon acceptance, pass the content on to GEOPLATFORM.gov for loading. ‐ Quality Assurance includes spot checking for competency of GEOPLATFORM.gov ‐ First responder to all public enquires.
‐ Oversight in Open Records Incentive Outreach Program
3. RWTP OUTREACH PROGRAM 3.1 Rollout. Major events spread over the first year playing primarily to the urban development real
estate and investor community showing them how use of RWTP Model can make them more
profitable and/or effective, explaining that properties close to transit and many other amenities is
where, going forward, where we MUST build to remedy increasing demand for Carbon Footprint
Reduction. Sustainable Communities development is promoted by playing to the profit motive of the
private sector and the service motive of the housing advocate NGOs.

DETAILED LAYER DESCRIPTIONS A.1 DESTINATIONS Layer (includes all Amenities / Destinations)
A.1.1 Design. According to section 2.4 the RWTP Intellectual Property Plan, all commercially sourced
content is not shared with GEOPLATFORM.gov directly, but only the embodiment of all the 7M
parcels out of 82M highly likely to be destinations in support of Sustainable Communities. The filter
takes two queries:
QUERY 1. 3rd Party finds all nonresidential parcels with buildings/improvements.
NOT {Parcel Land Use Code = Residential} AND {Improvement Value > $0}
QUERY 2. To find all 'unimproved' and/or untaxed parcels without improvement value. Of All
parcels, use additive queries of these text strings within the OWNER NAME field. (and
others to be determined)
‐ Park ‐ Recreation ‐ Town
‐ County ‐ State ‐ District
‐ School ‐ Elementary ‐ Middle
‐ K8 K12 ‐ Library ‐ Hospital
‐ Civic ‐ Clinic ‐ Facility
‐ Community ‐ State ‐ Playground
‐ Church ‐ Temple ‐ Mosque
‐ Forest ‐ Woods ‐ College
‐ Municipal ‐ University ‐ Daycare
Destination Map Below is a combination of all parcels found in Query 1 and Query 2 merged together in a
single parcel Layer of about 8% of the total parcels.
FIGURE 5
Destination Map Layer (All parcels found as the combined result of Query 1 and Query 2)
A.1.2 Implementation. Current stock is amended with direct acquisition from compliant counties until all open
record parcel map databases are in the national parcel layer.
A.1.3 Final Disposition. The DESTINATION LAYER is not submitted to end user since, by having the UNIT
COUNT value included, competes with commercially offered services.
10 Relative WALK/TRANSIT Potential Layers BSI(C)2015
A.2 Relative WALK Potential Layer
A.2.1 Design. First step is to buffer the boundary of each and every destination/amenity parcel in
the DESTINATION Layer by a distance of 1/2 mile. If the UNIT count of a DESTINATION parcel
is greater than 1, the buffer around such parcel is generated the same number of times as
its assigned UNIT Count. For example, a parcel with the USE CODE of Commercial and a UNIT
Count of 8 will have eight buffers around itself, representing potentially 8 different retail
outlets to walk to rather than the DEFAULT count of 1.
FIGURE 6
Destination Parcels buffered by 1/2 Mile
Next, the total number of buffers that touch or surround a parcel is assigned to each parcel as its
Relative WALK Potential. As can be seen in FIGURE 7, the bright colors represent areas from where the
WALK Potential is intense to where there is no potential at all.
FIGURE 7
Countywide Relative WALK Potential Layer
11 Relative WALK/TRANSIT Potential Layers BSI(C)2015
A.2.2 Implementation. All needed additional content, boundaries and attributes are assembled and
subjected to a worm that assigns a Relative WALK Potential value to each and every parcel in
the national parcel layer.
A.2.3 Final Disposition. The final disposition of the Relative WALK Potential layer is one of thee
delivered components including:
A.2.3.1 Digital Parcel Boundaries
A.2.3.2 Relative WALK Potential as an extended attribute assigned to each parcel boundary.
When Relative WALK Potential values (1 ‐ 5) have been assigned to all 82M open record
parcels, the result is submitted to be displayed on GEOPLATFORM.GOV as a thematic
Layer.
FIGURE 8
Sample Relative WALK Potential Layer displayed within GEOPLATFORM.gov
Numbers are assigned to each parcel representing the relative number of 1/2 mile buffers
around each and every destination that touch or surround its parcel boundary polygon.
For example, if a parcel were within or touching 92 1/2 mile buffers, it is assigned a
Relative Walk Potential of 3 (third regime: 76 – 119)
12 Relative WALK/TRANSIT Potential Layers BSI(C)2015
A.3 Relative TRANSIT Potential Layer
A.3.1 Design. A rapid/mass transit station and bus stop Layer is established as said facilities are present within the 1,710 counties in the initial implementation of existing open record counties. A 1/4 and 1/2 Mile walk distance buffer is generated around every transit facility and every parcels within or touching or not touching such buffers are assigned a Transit Access Values as follows:
< 1/4 MILE of Transit (Very Near) < 1/2 MILE of Transit (Somewhat Near) NOT NEAR Transit (Not Near)
A.3.2 Implementation. Acquisition and compilation of the needed bus stop / transit station Layer
will start with known sources of mass transit stations at a national level and will be
augmented by outreach to every COG to collect all available digital lat long of every point of
access to or egress from every bus, train and mass transit operation in each county. As
collected, the NPLCSP buffers each point and assigns Relative Transit Access Values (see
above) to each and every parcel in the 1,710 open record counties.
A.3.3 Final Disposition. The final disposition of the Transit Potential layer is one of thee delivered
components including:
A.3.3.1 Digital Parcel Boundaries
A.3.3.2 Relative WALK Potential Value as an extended attribute
A.3.3.3 TRANSIT Potential Value as an extended attribute
When TRANSIT Potential values have been assigned to all 82M open record parcels, the
result is submitted to be displayed on GEOPLATFORM.GOV as a thematic parcel Layer.
FIGURE 9
Sample Relative TRANSIT Potential Layer displayed within GEOPLATFORM.gov
Relative Transit Potential Each parcel is rated whether its boundary
is with 1/4Mile, ½ Mile or NOT near transit (>1/2 Mile).
13 Relative WALK/TRANSIT Potential Layers BSI(C)2015
A.4 Relative WALK and TRANSIT Potential Layer Operation
To minimize risk, meet expectations, avoid data usage constraints and hold down costs, on the
first day the RWTP shall be limited in two ways:
A.4.1 Limited Coverage. As mentioned in Section 1.2, the only digital parcel map databases to
be included in the RWTP are from counties charging a subscription price of $200 or less.
All other counties are considered closed record counties. In addition, even if the
subscription price is <= $200, but there are constraints on its reuse of any kind, said
content shall also be considered closed record and not included due to potential data
sharing violations.
A.4.2 No Situs Address Use. In keeping with the intent of Section 3, Intellectual Property Plan,
situs addresses cannot be referenced within the RWTP due to attendant commercial value
preventing public domain use. This is not a problem, however since the INITIAL intent of
the RWTP is not to retrieve and view a specific address but to look at patterns of relative
potential. Further reason to discourage expectations of individual parcel ratings is that
each parcel is only assigned a relative category of WALK potential. A specific rating
requires subsequent use of a dedicated WALK Score services. On the up side, RWTP is
aimed at enabling everyone to better determination of where to invest in development
that accentuates the positive of the existing situation to maximize creation of highly
pedestrian oriented transit, centric communities that minimize automobile use and
attendant carbon footprint.
In regards to locating a parcel, instead, GEOPLATFORM.gov is to set an expectation that
the user can zoom to any community / place by selecting a location in the USGS
Geographic Names Information System (GNIS). As for land base, the parcels will fit
reasonably well 90% of the time over public domain or commercial land bases, the choice
is up to GEOPLATFORM.gov. On the first day, no reference to individual addresses will be
provided, only place names.

RWTP INTELLECTUAL PROPERTY PLAN
B.1 RWTP INTELLECTUAL PROPERTY PLAN
No Private Sector Data is shared directly with GEOPLATFORM.gov. as follows: B.1.1 Improvement Value. Exclusively in‐house function to identify destinations records. B.1.2 Owner Name. Exclusively in‐house function to identify destinations records. B.1.3 Use Code. Exclusively in‐house function to identify destinations records. B.1.4 Unit Count. Of all records, ~7% are released to NPLCSP with only Unit Count and lat long
values. However, Unit Count is never shared with the GEOPLATFORM.gov. Instead, half mile buffers are generated around each Destination Parcel boundary. IF unit count is 2 or more, 2 or more copies of the buffer are generated.
The boundary of each parcel is in turn intersected with all Destination Parcel Buffers to count up how many Destinations can be walked to within 1/2 mile from the destination's perimeter. Funded by the GEOPLATFORM.gov, geoderivatives
Relative WALK Potential indicator values (1 ‐ 5) enter the public domain derived in part from private sector content but with no prior art.
Relative TRANSIT Potential indicator values (Very, Somewhat, Not near) enter the public domain
