EXECUTIVE SUMMARY

In this project , The Mulford Corporat ion, the nonprof i t aff i l iated

with the Munic ipal Housing Author i ty for the City of Yonkers

(MHACY), wi l l s ignif icant ly increase green infrastructure prac-

t ices across i ts affordable housing system. The project wi l l not

only reduce runoff into three regional watersheds, the Saw Mil l ,

Bronx, and Sprain Rivers, but wi l l advance the agency’s c l imate

res i l iency goals . Act iv i t ies wi l l take place at 10 propert ies, in-

c luding older, h igh-r ise bui ld ings near the Saw Mil l R iver and

smal ler-scale homes and apartments in the other watersheds.

Taken together, the propert ies are home to hundreds of low-

income people. In the project , more than 1,800,000 square-feet

of MHACY managed propert ies wi l l be converted to natural

b iof i l ters , captur ing an est imated 373,560 gal lons (49,943 Cubic

Feet) of stormwater annual ly. In addit ion, 427 new trees wi l l be

planted to capture more ra inwater and provide shade over t ime

to mit igate heat hazards. Groundwork Hudson Val ley (GWHV) is

the main partner and is working with MHACY on a broader Cl i -

mate Safe Neighborhood in i t iat ive. I ts youth corps, the Green

Team, wi l l ass ist in the project p lant ings to further their conser-

vat ion sk i l l s .

PROJECT OBJECTIVES: ENVIRONMENTAL AND SOCIAL

Yonkers is the fourth largest c i ty in New York State, with an av-

erage populat ion density of 11,178 people per square mi le ( tota l

of 18 square mi les. ) The c i ty offers a safe, fami ly-or iented com-

munity to an increas ingly diverse and growing populat ion. As

the cost of l iv ing in Manhattan and surrounding areas has in-

creased, Yonkers populat ion grew 2.75% since 2010. The mayor

and planning board of Yonkers recognize the need to grow sus-

ta inably. The City of Yonkers has introduced a Green Develop-

ment mandate with guidel ines for increas ing the qual i ty of l i fe,

a i r, increas ing access to open space, ensur ing environmental

just ice for res idents who have faced socia l and f inancia l hurdles,

and lower ing the heat is land effect in Yonkers through the intro-

duct ion of plants and other Green Infrastructure (GI ) systems.

This project proposes that Groundwork Hudson Val ley (GHV)



work with the Mulford Corporat ion to introduce GI into se lected

publ ic housing developments in Yonkers. The object ives of this

project , GI in Mulford res idences, a l ign c losely with the Green De-

velopment mandate approved by the c i ty. This feas ib i l i ty study wi l l

analyze overal l condit ions in Yonkers, and determine which of the

Mulford Corporat ion s i tes best lend themselves to effect ive green

infrastructure insert ions. GI pract ices for the Mulford propert ies

wi l l inc lude the fol lowing: Bioretent ion associated with down-

spout disconnect ion, stormwater street trees, stormwater harvest-

ing and reuse, and urban forestry for stormwater mit igat ion.

There are two pr imary and over lapping goals for th is project :

environmental and socia l .

ENVIRONMENTAL GOALS

Stormwater runoff : GI i s an effect ive stormwater mit igat ion meth-

od, s lowing the rush of water, often containing pol lutants, into

water treatment fac i l i t ies , or in the worst case, combined storm-

water and sewer overf low (CSO) which can, in this case, go di-

rect ly into the Hudson River and other water bodies in Yonkers,

such as T ibbets Brook, the Saw Mil l R iver, the Bronx River, and

other smal l lakes and ponds. Yonkers Joint Wastewater Treat-

ment P lan, which handles wastewater from 22 munic ipal i t ies and

7 separate sewage distr icts , i s over capacity dur ing storm events.

Whi le the (11) green infrastructure insert ions at Mulford proper-

t ies covered in this study would not, in themselves, s ignif icant ly

reduce stormwater at the Yonkers fac i l i ty, an accret ion of l ike

projects would have a s ignif icant effect in lower ing costs for the

c i ty and in extending the l i fespan of the ex ist ing fac i l i ty.

Yonkers has extreme topography, and much exposed bedrock in

addit ion to paved surfaces, and therefore has s ignif icant storm-

water f lushing into street drains rather than inf i l t rat ing into the

ground water system. Reducing the volume of stormwater runoff

into c iv i l engineered systems, and holding i t on s i te with bioen-

gineer ing and plant mater ia ls , wi l l begin to restore natural pro-

cesses to urban areas. As urban soi ls begin to funct ion through

plant ing and proper grading, the soi l wi l l increas ingly be able to

support healthy plant l i fe. S lowing the movement of stormwater

in part icular neighborhoods wi l l reduce both local and regional

f looding.



Slowed runoff keeps stormwater from col lect ing as much de-

br is , chemicals , sediments, and other pol lutants. Lower dis-

charge rates, both into the treatment fac i l i ty and by way of

CSO’s, wi l l reduce pol lutant loads into regional streams and r iv-

ers . GI pract ices a l low sediment to be f i l tered near i ts source;

often pol lutants are broken down or sequestered by plant ma-

ter ia ls .

Trees and plants: Introducing more plant mater ia l into prop-

ert ies, greening them, wi l l increase evapotranspirat ion, which

wi l l lower summer temperatures. This has the environmental

benef i t of lessening re l iance on air condit ioning in the summer.

Large canopy trees a lso lower heat indexes by increas ing shade.

Trees and plants hold water on s i te and re lease i t s lowly, pro-

v id ing pass ive i r r igat ion and reducing landscape maintenance

costs for The Mulford Corporat ion and increas ing the health

and longevity of the trees and plants on the propert ies.

SOCIAL GOALS

Plac ing green infrastructure in publ ic spaces provides v isual

access to natural processes which has educat ional benef i ts ,

as wel l the environmental and f iscal benef i ts descr ibed above.

Res idents of se lected publ ic housing units would become aware

of natural processes surrounding their apartments and homes.

Reducing local temperatures wi l l lessen the f inancia l burden on

res idents; p lant mater ia ls surrounding publ ic housing wi l l pro-

v ide shade and cool the areas considerably, reducing the need

for res idents to use a i r condit ioning which some cannot afford.

Economic and socia l project goals inc lude providing employ-

ment and tra in ing for young people in Yonkers, as the GI e le-

ments are bui l t and maintained. The f inancia l model ing for

this GHV grant is based on a combinat ion of volunteer and paid

labor which wi l l be returned to the community, increase com-

munity involvement, and teach both career-bui ld ing sk i l l s and

the value of local stewardship to those who ass ist in bui ld ing

the projects .



PROJECT DESCRIPTION

The bui ld ings owned and managed by The Mulford Corporat ion which were considered for GI pract ices fa l l into two pr imary cat-egor ies, s ingle or adjoined townhouses with shared parking areas and shared front yards; and apartment bui ld ings with shared en-trances and elevators. In general , with some var iat ions based on avai lable space and to-pography, the Green Infrastructure (GI ) prac-t ices for the townhouses and the GI pract ices at the two apartment towers wi l l the same.

Universal i ssues to be amel iorated are:• Eros ion of topsoi l , and sediment loading

into local water bodies• Puddl ing, poor drainage, muddy areas

around housing structures • Landscapes requir ing extreme maintenance• Lack of plant mater ia l to shade pavements• Extreme, local ized heat condit ions (urban

heat is land effect ) in areas where paving dominates the landscape

• Over loading the CSO system in heavi ly paved areas, with excess ive stormwater runoff

Soi ls in Yonkers are predominant ly Urban Land-Char l ton Chatf ie ld ( rocky with 3-45% slope), and Urban Land-Paxton Woodbridge (10 - 25% slope.) Chatf ie ld soi ls are ex-tremely rocky and steep with numerous bed-rock outcroppings. These diff icult and shal-low soi ls , further degraded by bui ld ing and rebui ld ing, do not hold water wel l , adding to the diff iculty in growing plant mater ia ls and sequester ing ground water.

TOWNHOUSES / DUPLEXES• Bioretent ion can be used at the base of s lopes in front yards. P lant ings surround-ing the bioretent ion wi l l hold water and prevent eros ion. • Bioretent ion can be implemented at parking lot edges, captur ing storm water that sheet drains from the lot .• Downspouts can be disconnected from the townhouses, captur ing the storm water in c isterns. Overf low from the c is-terns can be channel ized to bioretent ion systems. Cisterns can be held and used for i r r igat ion of on-s i te plant ings. (Community gardens, community plant ings, etc. )• Shade trees should be planted to up-take stormwater near the curbs.• Any ex ist ing ra in leaders can be dis-connected or interrupted to direct water to bioretent ion areas.

Bioretention can be used at the base of slopes to retain water before it flows into the storm sewer. Gardens also provide habitat for pollinators.

APARTMENT BUILDINGS WITH SHARED ENTRANCES AND ELEVATORS

• Bioretent ion is a pract ice that can be used near apartment entrances, and near en-try s idewalks, and surrounding the propert ies e i ther near curbs or in street medians. • Large canopy shade trees should be in-sta l led in the bui ld ing courtyards, as needed, to provide shade and hold water both in the tree, and root systems. S i lva Cel l (or s imi lar technologies) i s an effect ive system to use for paved areas. The trees wi l l be ensured to surv ive, and the trees can be connected into a cont iguous system that holds water just be-low paved level .• In lawn / green areas, urban “forests”, or groves of trees, can be planted to reta in water on s i te in the roots, t runks, and leaves of trees, u l t imately a l lowing the water to evapotranspirate into the atmosphere.

PERMITTINGFor those s i tes within 200 feet of any fresh-water body, there may be rev iew required by the Army Corps of Engineers, and permit-t ing wi l l be required from the NYSDEC. Al l s i tes wi l l require land disturbance permitt ing by the City of Yonkers. I f any of these s i tes disturb more than 5,000 SF each, those s i tes shal l require a State Pol lutant Discharge E l im-inat ion System (SPDES) general permit .

Silva Cells allow trees to thrive in harsh urban conditions, and with roots spreading freely and between one another, the trees store more water.

YONKERS SITE CONDITIONS

The Mulford propert ies in this study are near ly a l l s i ted in densely populated ar-eas, near or adjacent to major highways. Two are in downtown Yonkers. Due to the dense and paved condit ions of most of the propert ies, the annual recorded tempera-tures are much higher than housing in vegetated areas.

Doran Sr. Townhouses8. Lawrence Chr istopher Townhouses9. Judge Albert F iore l lo Townhouses10. Andrew Smith Townhouses


F looding to a depth of more than 4 inches is an issue that affects a l l the publ ic hous-ing which is near to waterways or highway corr idors. Also downtown Yonkers, due to the preponderance of paving, is prone to f lash f looding. GI pract ices would a l lev iate some of the f looding near the housing.

The extreme s lopes in Yonkers, coupled with rocky soi ls and mult ip le areas of ex-posed bedrock, intens i fy the damaging ef-fects of stormwater and f looding, and the diff iculty of plant ing large canopy trees in certa in areas.

Steep slope behind three towers is prone to mudslides and continual erosion. Bioretention should be at base of hill.

Parking Lot along Walsh Road; all three parking lots should have permeable paving installed.

Saw Mill River next to Walsh Road, across from Walsh Houses, floods occasionally and receives sediment and point source pollutants.


There are several hous-ing projects in the v ic in i ty - - as wel l as the avai labi l i ty of open space, the War Memori-a l Park. The towers are in a densely populated part of Yonkers, down-town. Due to the c lose proximity of the Saw Mil l R iver, vehicular c i r-culat ion is l imited.

Hydrology on the s i te is problematic. Due to a very steep s lope di-rect ly behind the tow-ers, with reta ined soi l and rock, storm water washes downhi l l past the apartment bui ld-ings, across the park-ing lots inbetween the bui ld ings, and into the Saw Mil l R iver. The centra l tower is in the 100 and the 500 year f loodpla ins, and the easternmost tower is near the100 and 500 year f loodpla ins.

Topography is extreme and there is exposed bedrock on the steep, reta ined s lope, a long with thin soi ls . Much of the s i te is over 25% slope, in fact , i t i s wel l over that. Rainwa-ter streaming rapidly downhi l l erodes the soi l , caus ing sediment and point source pol-lut ion to f low direct ly into the Saw Mil l R iver.There was a mudsl ide on this s lope in 2018, which overturned reta in ing wal ls and caused bui ld ing evacuat ion.

The townhouses are not in e i ther the 100 year or 500 year f lood-pla ins. However, ex-posed bedrock and the preponderance of high-way infrastructure near the townhouses causes stormwater to run into the propert ies.

There are steep s lopes on both s ides of the property, with the high-er s ide being where Route 87 passes by, and the property s lop-ing from there downhi l l to Centra l Park Avenue.
