Summary of findings
Leonard Street NW reads, across its full half-mile, as two corridors joined at a rail crossing. The historic core at the river end is compact, walkable, and well-governed; the auto-era stretch toward Alpine is broken and thinly occupied. The diagnostic that follows affirms the strength of the core and locates the corridor's weakness precisely. Two dimensions carry the score down, and both sit in the western half: a severe economic-resilience shortfall and a continuity problem the auto-era stretch introduces. Neither is the kind of weakness that requires rebuilding the corridor.
This diagnostic measures functional diversity: the capacity of a commercial street to support a range of complementary uses, drawing people for different reasons and at different hours, and to hold up across economic cycles. A street with that range carries its own resilience; a street that leans on a single use does not. The instrument reads six dimensions of that capacity and sorts the result into four standings, from Healthy at the top to Critical at the base.
On that measure, Leonard sits in the At-risk standing, near the threshold of the Moderate tier above it. The position is more favorable than the label suggests. The corridor is not weak across the board. It is sound to strong on most of what the instrument reads, with two weaknesses that share an address. Its governance, its building stock, its daily activity, and its experiential range are assets. Two dimensions fall far enough to carry the score down, and both sit in the auto-era western half: economic resilience, where vacancy is high and the tenancy overwhelmingly discretionary, and continuity, where a rail crossing and surface parking break the western edge. The street looks busier than it is resilient, and more whole than it is continuous.
That diagnosis carries an unusually favorable implication. The strengths that are slowest and most expensive to build- sound bones and organized leadership- are already in place. The weaknesses are the comparatively addressable kind. The corridor does not need rebuilding. It needs the everyday tenancy restored to its interior and its western edge reconnected.
The corridor's direction reinforces the point. Its trajectory reads as regenerating, hollowed-out: a street whose frame, leadership, and lively core remain intact while the connective tenancy between them has worn thin, and where demand, having thinned, can be rebuilt. The macroclimate is a net tailwind, unevenly distributed. Population growth, a young workforce, and a wave of nearby investment are flowing toward the corridor, while the two countervailing pressures- a cooling consumer economy and an aging base of local owners- bear on precisely the resilience the corridor most needs to protect.
The central finding is straightforward. Leonard Street NW has completed the difficult part of corridor health and stalled on the two comparatively addressable ones, both concentrated in its western half. Its near-term outcome is unusually within reach, and the difference between recovery and a missed opportunity is largely a matter of stewardship. The pages that follow set out the instrument and method, the corridor as it stands, the diagnostic in full, the macroclimate acting on it, the trajectory, the corridor's alignment with the City's adopted plans, and what recovery would take.
Rhizeleonard street nw · functional diversity diagnostic0301 the instrument
The instrument
This diagnostic measures functional diversity: the capacity of a commercial street to support a range of complementary uses that draw people for different reasons and at different hours, and to hold up across economic cycles. A functionally diverse corridor carries its own resilience, the way a varied planting does and a monoculture does not. The instrument scores that quality across six dimensions, each on a 0-to-100 scale, then combines them by weight into one corridor score on the same scale. The six dimensions, heaviest first:
Whether the corridor offers a real spread of uses or leans on one. The heaviest dimension, because a street that rises and falls with a single use is fragile regardless of how busy it looks on a good night. Reads the count of distinct use categories, the dominant use's share of active frontage, upper-floor (vertical) use, and the presence of daily-needs anchors.
How well the corridor holds up across demand cycles. The second-heaviest dimension, and on most struggling corridors the one doing the real downward work. Reads local ownership, the vacancy rate and how long units sit empty, the spread of demand cycles the tenancy draws on, and the share of non-discretionary uses that hold steady in a downturn.
Whether the street reads as a continuous active edge or a broken one. The dimension a windshield survey most often gets wrong. Reads frontage activation, the largest continuous gap, flat-lot prevalence, and vacancy activity status.
When the corridor is actually active. Reads the share of frontage active in the morning, midday, and evening, and how many uses carry across more than one of those windows.
The condition of the built environment and what it has to work with. Reads facade, signage, windows, lighting, and sidewalk, alongside building-stock quality, walkability, and transit access.
The social and organizational infrastructure behind the street. The lightest weight, and the one dimension set by professional judgment rather than computed from data. Reads owner residency and local ownership, the activity of a business or neighborhood association or improvement district, connection to the surrounding neighborhood, and visible coordinated investment.
Each dimension and the overall score share four standings: Healthy (80-100), Moderate (60-79), At-risk (40-59), and Critical (0-39). The standing is a snapshot of where the corridor sits today. Separately, the diagnostic assigns a trajectory, where the corridor is heading and why, read from its standing against the macroclimate: the regional conditions a single corridor sits inside but cannot control, including population and migration, the workforce and employment base, the housing pipeline, the capital climate, major projects, and ownership succession, read as tailwinds or headwinds behind the corridor's own numbers. The two answer different questions and are reported separately. The instrument synthesizes six decades of corridor and urban research and is described in full in the appendix.
Rhizeleonard street nw · functional diversity diagnostic0402 methodology
Methodology
The assessment is a desk compilation and analysis paired with a boots-on-the-ground field survey. It draws on Kent County assessor and parcel records, City of Grand Rapids business licensing, Google Places activity data, spatial parcel analysis, and a full walk of the corridor. It does not include stakeholder interviews; it reads the corridor from its records, its maps, and its street. Five of the six dimensions compute from observed and recorded data. Community Rootedness & Governance is the one qualitative, hand-set dimension, scored against the anchored scale.
Two notes on confidence
An honest instrument states its own limits. Two apply here. First, the day-part activity reads began as posted and listed business hours and were then reconciled against measured Thursday Popular Times for the sixteen of twenty-three venues Google reports; the busyness data firmed the afternoon and evening and confirmed the early morning as the corridor's lighter window, where coverage is thinnest. Second, the Economic Resilience inputs reflect a point-in-time vacancy count, which captures the rate cleanly but not its duration or the marketed-versus-held status behind it. Both notes are carried forward into the dimensions they affect.
80-100 Healthy · 60-79 Moderate · 40-59 At-risk · 0-39 Critical. These apply to the weighted corridor score and to each individual dimension alike.

The corridor today
Boundaries and character
Leonard Street NW runs east to west across the heart of Grand Rapids' Westside. This diagnostic covers the corridor's full extent, from the Turner Avenue gateway at the river end west about a half-mile and six blocks to Alpine Avenue: fifty-six parcels, both sides, from 400 to 800 Leonard, of which roughly 41 carry occupied storefronts. It does not read as a single street. At about the 600 block, near Elizabeth Avenue and a rail crossing, its character changes. East of that line is a historic two-story brick commercial core built to be walked. West of it is an auto-era stretch of single-story buildings set back behind parking. The two halves score differently because they function differently, and that division organizes most of what the diagnostic finds.
The corridor's destination identity is concentrated in its eastern, historic core, between roughly 430 and 537, where the Quarry cluster forms a food-and-drink draw that reaches well beyond the neighborhood. Mitten Brewing, Long Road Distillers, People's Cider, Two Scott's BBQ, Chicago Gyro, and The Comedy Project sit within a few hundred feet of one another and give that core a dense, high-energy center. The western half, beyond the rail crossing toward Alpine, runs thinner and more auto-oriented. Leonard's identity is established and externally legible: the Quarry cluster has made it a recognized destination across Grand Rapids, and that recognition is an asset most corridors spend years trying to build.
Who shows up here
The corridor serves three overlapping populations, and the diagnostic reads each differently.
A regional destination crowd. The Quarry cluster draws diners, drinkers, and comedy audiences from across Grand Rapids, concentrated in the late afternoon and evening. On the May field survey, at half past five on a Thursday, that crowd was already arriving. It is the corridor's most visible user base and its current economic engine. It is also, importantly, a visitor base rather than a resident one.
The Westside itself. A dense, historically rooted residential neighborhood lives around Leonard. It shops the corridor for some daily needs already: three groceries, Ralph's and Supermercado Michoacan among them, give the street a real grocery presence. But that everyday base is thin against a tenancy otherwise built for going out, and a good deal of the routine spending these households generate, on groceries and the everyday errands a neighborhood runs by daylight, still leaves the corridor for destinations elsewhere.
The population its governance represents. Long-time Westside families and newer arrivals drawn by the food scene and by housing pressure moving up from downtown. That mix is the corridor's strength and the source of a quieter tension beneath its civic life, addressed in Section 06.
As neighborhood context, ZIP 49504, the Westside, holds about 17,062 households at a median household income of $70,119, and skews young, with a median age of 32.5 (U.S. Census, ACS five-year estimates). The quarter-mile walk-shed, the households close enough to support this corridor on foot, is a smaller and lower-income subset, about 1,250 households at a median near $51,000. The Demand and Capacity section reads that walk-shed against what the corridor can support.
Rhizeleonard street nw · functional diversity diagnostic06The built environment
The built environment splits with the corridor. From roughly 430 to 537, the stock is sound 1900-to-1925 two-story brick: the DeVries jewelry frontage established 1901, the restored brewery and distillery landmarks, fine-grained storefronts built to the sidewalk. West of the rail crossing the stock shifts to auto-era single story- AutoZone, Advance Auto, the Belden Brick supply yard, Taco Bell, and the Walgreens pad- set back behind parking with frontage spread thin. Across the full corridor, surface parking and vacant land account for about 44 percent of the street and flat lots for roughly 17 percent of frontage, concentrated in the western half. The eastern core reads as a continuous active edge; the western half does not. The legacy brick is the corridor's most durable asset and the hardest thing on the street to replace.
One built-environment variable stands out, and it sits at the east gateway by the river. The former Brann's, at 401 to 405 Leonard, stands intact but dark: a large, prominent building at the corridor's entrance that reads as absence rather than activity. A roughly $30 million, hundred-unit mixed-use redevelopment with a ground-floor restaurant has been proposed for it. As of June 2026 the project has not broken ground, with no demolition or building permit on file and the site still reading as defunct on the development trackers. If it proceeds, it is the single most important built variable in the corridor's near-term trajectory, and Section 06 treats it as such.
Condition across the corridor is mixed but workable. The streetscape and frontages score in the middle of the range: sound where they are cared for, tired where they are not, with the deferred maintenance characteristic of a street that is regenerating rather than fully regenerated. This is a built environment that rewards incremental, facade-level reinvestment. It does not call for wholesale rebuilding.
A structurally intact, socially organized, active street, its physical and civic foundations in place. What it lacks sits in its tenancy and, toward the west, in its continuity.

Overall score
Leonard Street NW earns a weighted functional diversity score of 59.0 out of 100, its six dimension scores combined by their weights. That places the corridor in the At-risk standing, in the upper half of the band and about a point below the Moderate threshold of 60. The standing describes where the corridor stands today; it is a snapshot, not a verdict on where it is going.
a point below Moderate
Each bar shows the dimension's 0-100 score; the grey line marks the Moderate threshold of 60.
What makes this score of 59.0 worth reading is how it is assembled. The headline is not the average of six middling numbers. It is the product of one strong dimension, two sound ones, and two that fall far enough to carry the total down. The table below shows how each dimension's score, multiplied by its weight, builds the corridor total, and exactly where the points are lost.
| dimension | score | weight | contributes | forgone |
|---|---|---|---|---|
| Use Mix & Concentration | 80 | 0.25 | 20.00 | 5.00 |
| Economic Resilience | 36 | 0.20 | 7.20 | 12.80 |
| Continuity & Gap Pattern | 37 | 0.18 | 6.66 | 11.34 |
| Day-Part Activity Coverage | 66 | 0.15 | 9.90 | 5.10 |
| Physical Conditions & Legacy Assets | 56 | 0.12 | 6.72 | 5.28 |
| Community Rootedness & Governance | 85 | 0.10 | 8.50 | 1.50 |
| Corridor score | 1.00 | 59.0 | 41.0 |
Contributes = score × weight. Forgone = weight × (100 − score), the points each dimension leaves on the table.
Economic Resilience forgoes 12.8 of the 41.0 points the corridor gives up and Continuity forgoes 11.3, so together the two account for more than half the shortfall. Both trace to the same auto-era western half. The implication, developed across the findings that follow and quantified at the close of this section, is that the corridor's standing turns on one stretch of street, read twice.
Rhizeleonard street nw · functional diversity diagnostic09The corridor at a glance
Every storefront on Leonard, both faces, placed from county parcel geometry and sized to its frontage. A walkable destination core around the Quarry cluster, a daily-needs spine to the west, and a broken auto-era middle between them, which is where the continuity and economic-resilience scores concentrate.
Rhizeleonard street nw · functional diversity diagnostic10Dimension findings
Each dimension in weight order, with its score, its standing, and what the number means on this particular street.
The corridor carries a respectable spread, nine distinct occupied categories, and the food-and-drink cluster gives it real experiential range. That range leans discretionary. After the per-parcel frontage was tabulated, with the old Retail catch-all split into its functional categories, no single use holds more than about 21 percent of active frontage, which carries the concentration reading into the strong range. The everyday anchors are present- the Walgreens pharmacy now in-boundary and reading served, three groceries, two healthcare uses, two legal or financial- but the routine, recession-resistant base stays light beside the eating and drinking. Active upper-floor use, at about 18 percent, adds vertical mix the ground-floor read would otherwise miss.
The full-corridor re-walk added an upper-floor activation column to the survey, so this reading now captures vertical use the ground-floor scan would miss: active upper-floor occupancy runs about 18 percent, Pure Architects above a ground-floor shade shop among the examples. Earlier core-only versions of this dimension did not record upper floors.
This is the corridor's deepest weakness, and the lower of its two dimensions in the Critical standing, with continuity just above it. Confirmed vacancy stands at 21 percent, rising toward 37 percent once the unconfirmed western parcels are counted, and non-discretionary tenancy- the recession-resistant uses that keep a street solvent when discretionary spending tightens- sits near 17 percent of what is open. The thin everyday base is concentrated in the auto-era western half, and the corridor's national anchors, Walgreens, Taco Bell, AutoZone, and Advance, sit on investor-owned parcels, so a share of the corridor's rent leaves the neighborhood. One point worth noting against the prior, core-only read: extending the boundary west to Alpine raised this score rather than lowering it, by bringing the pharmacy and groceries into the count. The dimension improved and still defines the corridor.
The vacancy rate is read here as a point-in-time count. Whether those storefronts are actively marketed or quietly held is a question of landlord posture, and it materially changes how recruitable the corridor is. That distinction is a first-order task for any intervention.
A demand-capacity note. Vacancy and tenancy mix describe what occupies the corridor. They do not measure whether the surrounding neighborhood can support more, and on Leonard that is the more important question. The Westside's density and rootedness indicate substantial everyday spending, only part of which the corridor captures today: Ralph's and Supermercado Michoacan hold some of the grocery trade, but with the everyday base otherwise thin, a large share of routine household spending is still met elsewhere. That under-captured local demand is the strongest possible basis for recruiting need-based tenancy, and it is the cleanest distinction from demand that would have to be imported from wealthier households, which carries displacement risk. The trajectory section returns to this directly.
The demand-capacity read appears in full in the Demand and Capacity section: the walk-shed households and their everyday spending by category, set against what is open today and flagged void, underserved, served, or surplus. It is reported as a companion to this score rather than folded into it, so that vacancy is not counted twice.
Rhizeleonard street nw · functional diversity diagnostic11This is the dimension the full corridor exposes. Measured from parcel geometry, frontage activation reads 38.6 percent, the two longest continuous gaps both sit in the 600 block, 527 feet on the south side across the Belden and Advance auto run and 496 feet on the north side with the rail crossing inside it, and surface parking plus vacant land accounts for 44 percent of the corridor. The split is the story. The historic east half, 400 to 599, runs 53 percent activation at 11 percent flat-lot, a mostly continuous active edge. The auto-era west half, 600 to 800, runs 30 percent activation at 21 percent flat-lot, an edge broken by the rail crossing near Elizabeth Avenue, the surface lots, and the set-back auto-oriented frontage. A core-only read would have scored this dimension a strength; the full corridor reads it as the second drag on the score.
How to read it. The face is a 24-hour day, clockwise from midnight at the top, with 6am at the right, noon at the bottom and 6pm at the left. Each ring is a use category; the more saturated the color at an hour, the busier that category runs then, read from Google Popular Times for a typical Thursday relative to each venue's own weekly peak. A pale tint is a quiet hour and bare track is none. Offices and the neighborhood org publish no Popular Times, so the Office and Civic ring is estimated from a typical weekday office pattern and drawn dashed to mark it inferred rather than observed.
Leonard's measured Thursday rhythm builds rather than spikes. The street is thin before about nine- the Bagel Kitchen carries the early morning largely on its own, with the groceries, the pharmacy and the auto-parts stores opening through seven and eight- then fills fast and holds a broad active band from late morning to early evening, busiest from about four to six when the grocery, the Walgreens and the auto-parts trade peak together. Evening is genuine and spread across both halves: Long Road and the Mitten on the east, the Iron Well, Pickle and Pin and a late-running Taco Bell on the west carry real activity past nine, with a narrower tail in the bars and the party store to one or two in the morning. This is the one place the measured data revises the posted-hours read- the evening is not a thin or partial window but a true second peak- while it confirms the early morning as the corridor's soft spot, the same window an early-opening everyday use would fill. That is part of why this dimension and Economic Resilience move together: the thin hours are the everyday hours. One venue still reads quieter than it is- the Comedy Project, an east-side event space, shows no Popular Times panel and seats its audience from the rear, so even the measured read understates the corridor's true evening footfall.
Condition lands mid-range, averaging across facade, signage, windows, lighting, and sidewalk quality. The legacy building stock is an asset: solid, characterful, and worth restoring rather than replacing. What lowers the score is unevenness- well-kept frontages beside tired ones- and the deferred maintenance of a street that has not yet completed its reinvestment cycle. This profile responds to incremental, facade-level investment, not reconstruction.
Rhizeleonard street nw · functional diversity diagnostic12This is the corridor's strongest dimension by a wide margin, and the reason its regeneration thesis is credible. The 85 rests on documented infrastructure rather than impression. The West Side Corridor Improvement Authority is an established authority covering the West Leonard, West Fulton, and Stockbridge business districts, with tax-increment financing capacity audited within the City's Annual Comprehensive Financial Report. Its governing structure is settled. An eight-member board sits on staggered multi-year terms, several of them running to 2030, so seats turn over gradually rather than all at once. A sitting City Commissioner is among them, which keeps a direct line to City Hall, and the board meets in public every other month. Corridor work is staffed through a standing service agreement with the West Grand Neighborhood Organization, which gives the Authority working capacity beyond the board itself. Coordinated stewardship of this kind is the single hardest element of corridor health to manufacture, and Leonard already has it.
The Authority is also already operating the tools this corridor's recovery will use. It runs a facade and business-improvement grant program for owners inside its boundary, holds a development support policy that backs projects adding jobs, housing, or public greenspace, and carries an active agenda that currently includes the 400 Leonard redevelopment and the Powers-to-Alpine reconstruction. The instruments the recommendations in Section 08 depend on are ones the Authority can already reach for.
Identity belongs to this dimension. Who a corridor is for is part of its rootedness. One dynamic warrants naming, as an asset to steward rather than a flaw: the familiar old-guard and new-guard tension beneath a neighborhood changing as quickly as the Westside. Managed well through the redevelopment ahead, it is energy. Left unmanaged, it is friction. The score reflects the strength; the note reflects the vigilance the strength requires.
The Authority's exact tax-increment capture and annual budget appear in the City's Annual Comprehensive Financial Report; the figures would detail this dimension but do not change a read this well-supported.
What the score reveals
Read together, the six dimensions tell a coherent story. The slow, expensive, structural elements of corridor health are already sound. The corridor's governance (85), its legacy stock, its daily activity (Day-Part 66), and its experiential range (Use Mix 80) are assets, not liabilities. Its two weaknesses, economic resilience (36) and the western continuity (37), are the comparatively addressable kind, and they are not independent: both are functions of the auto-era western half, where the everyday tenancy is thinnest, the vacancy highest, and the active frontage most broken. Together those two dimensions give up more than half the corridor's shortfall. The distance between Leonard's 59.0 and a Moderate score is two recoverable problems in a single stretch of street, not absent bones or absent leadership.
Lifting the two western dimensions together- Economic Resilience from 36 toward the high 40s and Continuity from 37 into the low 50s, with the strong dimensions unchanged- carries the weighted score across 60 and into Moderate. The central finding of this diagnostic is that Leonard Street NW has built the slow, expensive parts of corridor health, its bones and its leadership, and stalled on the two comparatively addressable ones, both concentrated in its western half.
Rhizeleonard street nw · functional diversity diagnostic13the demand read
Demand and capacity
Vacancy and tenancy mix describe what occupies the corridor. They do not say whether the surrounding neighborhood can support more, and on Leonard that is the more telling question. This page sizes the everyday spending of the households within walking distance, converts it to the number of establishments each category can support, and sets that against what is open today. It is a companion to the functional diversity score, not folded into it, so corridor vacancy is never counted twice.
Walk-shed: a quarter-mile buffer around Leonard from Turner to Alpine, the corridor's full extent, from 2020 Census blocks and ACS five-year households and income (B11001, B19013). The score on the preceding pages reflects the full corridor, Turner to Alpine. The walk-shed median sits below the ZIP's $70,119, a smaller, lower-income trade area than the broader Westside.
| category | resident demand | supportable | open | status |
|---|---|---|---|---|
| Grocery and food-at-home | $6.92M | 2.0 | 2 | served |
| Pharmacy and health goods | $1.49M | 0.3 | 1 | served a |
| Full-service restaurants | $1.44M | 1.3 | 3 | surplus · visitor |
| Limited-service eating | $1.44M | 1.4 | 2 | served |
| Drinking places (bars) | $0.19M | 0.3 | 3 | surplus · visitor |
| Personal care and laundry | $0.56M | 1.6 | 2 b | served b |
| Fitness and wellness | $0.20M | 0.25 | 0 | below threshold |
| General and specialty retail | $2.82M | 2.4 | 5 | surplus |
| Modeled resident demand | ~$15.1M |
Demand is annual walk-shed spending by category. Supportable = demand divided by a neighborhood-format sales-per-establishment benchmark. Status sets open today against supportable. a Pharmacy now reads served: the Walgreens at the Alpine corner sits inside the corridor's full boundary. b Personal care is confirmed served: Stubble at 430 Leonard and VIP Barbers at 521 were verified open against the storefront log.
Residents underwrite the daily-needs core and the corridor largely delivers it. Grocery demand supports about two neighborhood-format grocers, and two are open, Ralph's and Supermercado Michoacan. Pharmacy, a confirmed gap in earlier core-only reads, is now served by the Walgreens at the Alpine corner. Full-service restaurants and bars read surplus on resident spending alone, exactly as a destination core should, since that demand is visitor and worker driven. What the walk-shed still leaves thin is the western half's everyday daytime trade. Read together, the shortfall the score flags as Economic Resilience is a demand-side, recoverable pattern rather than structural decline.
Sources: ACS 2019-2023 five-year; Census Business Builder; BLS Consumer Expenditure Survey 2023 at the walk-shed income band; 2022 Economic Census benchmarks (neighborhood format). The shed median sits at the band floor, so demand runs conservative; general retail is a catch-all, indicative.
Rhizeleonard street nw · functional diversity diagnostic1405 macroclimate
Macroclimate
The standing and the diagnostic describe the corridor itself. The macroclimate describes the field it sits inside: the regional tailwinds and headwinds a single street cannot control but cannot escape. It is read as direction rather than a score, because its role is to explain where the trajectory points and to frame what stewardship must protect. Seven indicators, each read from strong tailwind to strong headwind. The trajectory in Section 06 is a reading of the corridor against this climate, which is why the climate is set out first.
Grand Rapids has been Michigan's fastest-growing metro since 2020, up about 33,600 residents, roughly 3 percent. Kent County is one of the few Michigan counties projected to keep growing through 2050 while the state as a whole contracts.
The region ranks fifth among twenty peer metros for growth in 25-to-34-year-olds, up more than 14 percent, and was named the nation's No. 1 "City on the Rise." This is the precise demographic a food-and-drink corridor depends on.
Regional job growth is roughly flat for 2026, and the metro shed about 7,000 manufacturing jobs from 2023 to 2025, with replacement roles in hospitality and care paying less. Spending has narrowed toward the top third of consumers. A discretionary-heavy street feels this first.
Housing remains supply-constrained, with prices and rents still rising, and new households within walking distance are landing on and beside the corridor. The caveat: heavy A-class downtown supply is beginning to soften the top of the rental market, so lease-up timing matters.
Retail space is tight, near 4.2 percent vacancy with healthy absorption, which favors active storefronts. But elevated capital costs and strained construction financing are delaying larger builds. The leasing tailwind and the financing headwind roughly offset.
A concentration of catalytic investment sits one ring inward from Leonard: the proposed on-corridor Brann's redevelopment, GVSU's expanding downtown campus, state-backed Westside housing, and the roughly $800M Fulton & Market towers.
Statewide, about 23 percent of business owners are 65 or older and over half are 55 or older, with roughly half lacking a succession plan. Leonard's rooted, locally-owned base, its strongest asset, is aging, and the Brann's redevelopment is itself a succession event.
The push is decisively positive but lopsided. Every tailwind sits on the demand and capital side; both headwinds land on durability, consumer fragility and owner succession, which are the corridor's own weakest points. The region is supplying Leonard the demand to recover while pressing on the two things- economic resilience and rooted ownership- that the recovery has to protect.

Rhizeleonard street nw · functional diversity diagnostic15The transformational pipeline, in detail
Catalytic projects move a trajectory faster than any organic trend, so the pipeline warrants its own read. Leonard sits one ring out from a concentration of incoming investment, measured here from the corridor outward.
The former Brann's, at 401-405 Leonard. A proposed $30M, roughly hundred-unit mixed-use redevelopment with a ground-floor restaurant at the dark east gateway. As of June 2026 it has not broken ground, with no permit on file and the site still reading as defunct on the development trackers. If it proceeds, it would reactivate the gateway and place about a hundred new households directly on the street, the precise input a hollowed-out interior needs.
State-backed Westside housing near GVSU's expanding downtown campus, plus the continued build-out of the Bridge Street corridor (New Holland, Rockford Construction) that already ran the recovery play Leonard now faces. Sends resident demand and proven corridor-recovery momentum toward Leonard.
The Amway soccer stadium on the near Westside, a roughly $175 million, 8,500-seat venue at 230 Winter Avenue NW beside the YMCA. It topped out in May 2026 and opens in spring 2027, home to the city's new professional club. The Authority itself moved to support it. As a recurring crowd generator within walking reach of the corridor, it is an opportunity to capture pre- and post-game spending, especially once Leonard is healthy enough to hold that crowd on the street rather than let it pass through.
The Acrisure Amphitheater, open since May 2026 and drawing crowds through its first season, the $147M Factory Yards adaptive-reuse development on the near southwest side, the roughly $800M Fulton & Market three-tower riverfront project, and the Grand River restoration. A regional demand and visitor magnet radiating outward, with Leonard one ring beyond it.
The corridor's recovery does not depend on speculative growth. It depends on capturing investment and demand that are already arriving, on the corridor and immediately around it. The pipeline converts the regeneration thesis from a forecast into a base case, provided the demand is directed into the corridor rather than past it.

Standing and trajectory answer different questions. The standing, At-risk, states where Leonard stands today. The trajectory states where it is heading and why, read against the macroclimate, and there the reading turns more favorable. The corridor's trajectory is Regenerating, hollowed-out: a primary that names where the corridor sits in its cycle, and a modifier that names the shape of its weakness.
Life returning after disturbance, often into something new rather than the thing that was lost. Demand, activity, and tenancy are returning to a street that had thinned.
Sound edges and sound bones, but a gutted economic interior. The frame holds while the connective tenancy between the strong points has thinned to fragility.
The pairing is precise. A hollowed-out corridor keeps its frame, its governance, and often its liveliest blocks intact while the everyday tenancy that rounds a street out thins away between them. That is Leonard exactly. The frame holds, the leadership holds, the Quarry cluster is alive, and the connective economic tissue between them has worn thin. The corridor is not collapsing inward from structural failure. It has been hollowed on the demand side, and demand can be rebuilt.
Today's standing is At-risk; the direction of travel is upward. The distance between the two is almost entirely a single dimension, which is what makes the corridor's near-term outcome unusually controllable.
Rhizeleonard street nw · functional diversity diagnostic17What is driving it
Three forces are pushing Leonard toward regeneration, and one condition holds it back.
The Quarry cluster. A regional food-and-drink destination is a demand magnet, and Leonard's is established, full, and still growing. It proves the corridor can draw people. The task is to convert that proof into broader, more resilient tenancy.
400 Leonard, the largest potential driver. The proposed redevelopment of the former Brann's would reactivate the dark east gateway and place about a hundred new households on the street. It has not broken ground as of June 2026, so it is a force in waiting rather than in motion. A daily-needs tenant that cannot pencil against today's foot traffic may well pencil against a hundred new front doors if it does.
The governance. The 85 on Community and Governance is the mechanism by which a regeneration is actually steered. A corridor with sound bones and no organized body drifts. Leonard has the body.
The drag that remains is the condition this diagnostic keeps returning to: a thin, discretionary economic interior concentrated in the auto-era western half, where confirmed vacancy runs 21 percent and climbs toward 37 percent across the unconfirmed parcels. Until that interior is rebuilt, the corridor stays active but fragile, one demand shock from trouble.
Four outcomes, without stewardship
A favorable climate is potential energy, not a result. A regional tailwind does not automatically accrue to any one corridor. Left unstewarded, Leonard could land in any of four places, and three of them are losses.
The tailwind converts into rebuilt interior tenancy, retained local owners, and daily-needs anchors. Economic Resilience climbs, the headline crosses into Moderate, and it holds. The only outcome that requires active steering.
Capital and demand flow to the newer, shinier downtown projects while the existing interior storefronts and aging owners are skipped. The region grows; the corridor stagnates beside it. The likeliest path for an At-risk corridor next to a capital magnet when no one steers.
The tailwind arrives as rent and turnover pressure that washes out the rooted, locally-owned businesses and the old-guard whose stewardship earned the corridor's 85 on governance. The corridor recovers on paper while losing the rootedness that was its first asset. This is the difference between demand rebuilt from the households already here and demand imported from wealthier ones: the first regenerates, the second displaces.
If a demand wobble in a slow economy hits the discretionary base while succession closures stack up, vacancy deepens and the modifier hardens. Regenerating slips back toward Dormant, still hollowed-out.
Three of the four outcomes are losses, and they are the default ones. The incoming investment and the upward trajectory do not make the corridor safe; they raise the stakes. The same momentum that could rebuild Leonard's interior can also tip it toward monoculture, price out the rooted owners who are the corridor's first asset, or carry the street past the residents and the identity that make it the Westside's. Getting the corridor healthy now, before the wave fully lands, matters more here than it would in a quiet market.
Stewardship is the variable that selects Capture over the rest: the careful, accountable, long-term work of directing demand into the interior, protecting the keystone uses and rooted owners, and holding the corridor's identity steady, then handing that care to the owners, the City, and the Authority to carry on. A Rhize engagement does this work alongside the Authority, turning this reading into a sequenced program and the missing everyday tenancy into recruited tenants.
Rhizeleonard street nw · functional diversity diagnostic1807 alignment with adopted plans
Alignment with adopted plans
Leonard sits within a hierarchy of adopted City plans, from the citywide Community Master Plan down to the area-specific plan for the Westside, alongside an active zoning update. The diagnostic's findings align closely with their stated direction; this section reads that alignment plan by plan. A full reconciliation against every relevant policy is the first task of an engagement.
The City's 20-year land-use plan carries West Leonard as a Neighborhood Center, a designation intended to reinforce a pedestrian- and transit-friendly compact area with a mix of small-scale retail. Leonard's findings sit squarely inside that direction: the daily-needs recruitment this diagnostic recommends, and the proposed 400 Leonard redevelopment, advance the plan's housing and neighborhood-serving objectives directly.
The area-specific plan for the Westside, and the operative plan for this corridor: it covers the West Leonard Business District directly. The ASP places the corridor in a Traditional Business Area, a designation written to protect the Westside's historical storefront character and to encourage a vertical mixture of uses, first-floor retail, and higher density at the primary corners. Most pointedly, it calls for a mix of uses precisely to avoid the side effects of concentrating any single use. That is this diagnostic's central finding stated in the City's own adopted language. Leonard is over-concentrated in food-and-drink and thin on daily needs, and closing that gap is what the area plan has asked for since 2015. The diagnostic puts a number on a deficit the West Side ASP named a decade ago.
The City is updating its zoning to implement the Master Plan, with a form-based emphasis. How Leonard's uses and frontages will be regulated is being decided now, which makes this the moment to ensure the corridor's recruitment strategy and the emerging code reinforce, rather than work against, each other.
The City's five-year priorities plan organizes around six goals, three of which this corridor advances directly: Economic Prosperity and Affordability, through local business health and neighborhood-serving tenancy; Mobility, through the street reconstruction and a stronger pedestrian edge; and Engaged and Connected Community, through the corridor's organized governance. The plan is grounded in equity, the same lens the displacement risk in Section 06 is written to honor.
The City's adopted framework for street design, commissioned to deliver multimodal, well-maintained streets that strengthen neighborhoods and business districts. The Powers-to-Alpine reconstruction is the corridor's Vital Streets investment, and the corridor's interest is a rebuild that strengthens the continuous, walkable pedestrian edge the Continuity dimension rewards and that daily-needs tenancy depends on.
The Authority's own corridor agenda, its tax-increment district and active projects, is the delivery mechanism for everything above. The diagnostic is intended as an input to that work.
The interventions that lift the corridor's score are the same ones the City's plans already call for. Daily-needs tenancy answers the West Side ASP's explicit mix-of-uses goal and the Master Plan's Neighborhood Center designation; the gateway and street rebuild serve Vital Streets and the housing objectives; and stewarding the coalition protects the equity those plans assume. The corridor's strategy and the City's adopted direction are not in tension. They are the same program, read at two scales.
Rhizeleonard street nw · functional diversity diagnostic1908 what it would take
What it would take
These are the moves that convert the regional tailwind into Capture rather than Bypass or Displacement. None requires rebuilding the whole corridor. The work concentrates in two places, the economic interior and the western edge, both in the auto-era half.
The first lever. Recruiting recession-resistant, everyday uses- the routine daytime services a neighborhood uses by daylight, the kind that hold steady when discretionary spending tightens- lifts the economic resilience score of 36, the demand half of the corridor's shortfall. The corridor's under-captured local spending is the basis for that recruitment. This lever raises Economic Resilience; the western continuity needs the second, taken up in the next move. New households at the gateway, if the Brann's redevelopment proceeds, are what make those tenants viable.
The Brann's redevelopment is proposed but not yet permitted, so both whether and how are live. If it proceeds, the corridor's interest is a ground floor that reactivates the gateway as a continuous active edge and a restaurant that addresses the street rather than turning from it. Housing over an inactive ground floor would solve the household problem and leave the continuity problem in place. The gateway is the most actionable piece of the western edge; the rail-cut, surface-parked stretch beyond it needs the same reinvestment over time, and recruitment alone will not knit it back together.
The soft early morning and the thin everyday base are the same opening. An early-opening, everyday use- a bakery or cafe with a real breakfast trade, a market that opens at dawn- fills the quietest window and deepens the corridor's non-discretionary base at once. Two scores, one tenant.
A 21 percent confirmed rate, rising toward 37 percent across the unconfirmed western parcels, behaves differently depending on whether those storefronts are actively marketed or quietly held. Distinguishing marketed from held vacancy, a question of landlord posture and lease terms, tells the Authority where recruitment will land and where it will stall. This is governance work, and exactly the kind the corridor is equipped to do.
The governance score is the corridor's first asset. The redevelopment and the demographic pressure behind it will test the old-guard and new-guard balance that score rests on. Keeping that coalition aligned is not separate from the corridor strategy; it is its foundation, and the safeguard against displacement.
Rhizeleonard street nw · functional diversity diagnostic20conclusion
Conclusion
Leonard Street NW has built the parts of corridor health that are slow and expensive to build, and stalled on the parts that are comparatively addressable. Its bones are sound, its governance is strong, and its historic core is active after dark. Its weighted score of 59.0, an At-risk standing about a point under the Moderate threshold, rests on two recoverable dimensions rather than a structural verdict, and both of them sit in the auto-era western half.
What remains is to rebuild the corridor's everyday tenancy and reconnect its western edge, giving an active destination the economic ballast and the continuous frontage that turn it into a durable place. The corridor's task, and the Authority's, is to direct the arriving investment into that western half, and to keep the residents and owners who built the Westside within the regeneration.

About this diagnostic
The Rhize Functional Diversity Diagnostic is a proprietary instrument developed by Hannah Greening, founder of Rhize Urban Strategy. It synthesizes six decades of urban and corridor research, drawing on Jane Jacobs' conditions for street diversity, the succession and edge principles of permaculture design, mixed-use and retail-corridor practice, and the scholarship on local ownership and equitable development, into a single weighted scoring tool. The underlying findings are established; the six-dimension structure, the 0-to-100 scoring, and the weighting that produces a corridor's headline score are Rhize's original arrangement. A separate public self-assessment, the Corridor Health Quiz, averages the same six dimensions equally for a faster read; a quiz score and a report score are not meant to match.
The six dimensions
| dimension | weight | what it measures |
|---|---|---|
| Use Mix & Concentration | 0.25 | spread of use categories; dominant-use share; upper-floor (vertical) use; daily-needs anchors |
| Economic Resilience | 0.20 | local ownership; vacancy rate and duration; demand-cycle diversity; non-discretionary share |
| Continuity & Gap Pattern | 0.18 | frontage activation; largest continuous gap; flat-lot prevalence; vacancy activity status |
| Day-Part Activity Coverage | 0.15 | frontage active across morning, midday, evening; uses spanning more than one day-part |
| Physical Conditions & Legacy Assets | 0.12 | facade, signage, windows, lighting, sidewalk; building stock; walkability; transit |
| Community Rootedness & Governance | 0.10 | owner residency and local ownership; association or improvement district; coordinated investment; identity |
Standings
Leonard Street NW: 59.0 / 100, At-risk, upper band. Trajectory: Regenerating, hollowed-out.
Key terms
- Standing
- Where a corridor sits today, scored into four levels from Healthy to Critical. A snapshot, not a direction.
- Trajectory
- Where a corridor is heading and why, read from its standing against the macroclimate. One primary plus an optional modifier. "At-risk" is a standing only, never a trajectory.
- Macroclimate
- The regional conditions a corridor sits inside, read as tailwinds or headwinds and weighed with the standing to set the trajectory.
- Non-discretionary use
- A use people rely on regardless of the economic cycle, such as a grocer, pharmacy, or clinic. The anchor of a street's resilience.
- Households within walking distance
- The residential population close enough to support a street on foot; the everyday demand a corridor draws on.
- Keystone
- The use whose loss would unravel the block, usually need-based and locally rooted. An anchor draws demand; a keystone holds the structure and feeds the rest.
