A LEGACY OF BEAUTIFUL STREETS

Denver has a rich legacy ofparks, parkways, and tree-lined streets. Efforts to cre-

ate a green oasis date from 1867,when residents first planted streettrees. Parks were established earlyto add beauty, improve values,and give relief from the climate.Early in this century, the city com-missioned a series of park andparkway plans, all of whichincluded great parks connected by

tree-lined parkways, formal land-scaping, monuments, and the cele-bration of water. Residents and vis-itors alike benefit from this legacy.

The last major park and parkwayplan (1927) extended the systemthroughout the city and empha-sized tree-lined streets for residen-tial neighborhoods. Today, Den-ver’s civic character is expressed inthis system of green streets andneighborhoods.

WHERE TO PLANT TREES ON STREET

On curbed streets, trees should beplanted an equal distance betweensidewalk and curb. Where there is

no curb, trees should be planted as follows:

On 60 foot street, 11 feet from lot line.On 80 foot street, 17 feet from lot line.On 100 foot street, 20 feet from lot line.

Where there are car tracks on street, planttrees about four feet nearer to the lot linethan above. In blocks where trees arealready planted, try to conform to the same line.

Denver’s most beautifulneighborhoods have con-sistent plantings of street

trees that buffer and connect allhomes in a shared common space.These streets are some of the mostimportant public spaces in the city,creating a strong sense of commu-nity. The importance of beautifulstreets was renewed in the 1989Denver Comprehensive Plan,which states:

“The street tree will once again beDenver’s civic symbol. The oasisimage will be reinforced by reem-phasizing street tree planting andreplacement, and by continuingthe tradition of tree lawns anddetached sidewalks, especiallyalong major streets.”

Beautiful commercial streets are aDenver tradition as well. Todaythere is a growing interest inrestoring beauty to our commercialstreets. If streetscapes are comfort-able and secure for people, pedes-trian activity will increase. Therecent Lower Downtown andCherry Creek North streetscapeprojects are good examples ofhow lights, trees, paving, signageand furnishings can enhance andimprove the vitality of a commer-cial area.

The best designs give unity to adistrict by using consistent, formalarrangements of streetscape ele-ments suited to the scale and char-acter of the district. Each shouldalso share common materials and

elements with similar districtsthroughout the city. When this isachieved, every district can have asense of place that contributes toan overall attractive image forDenver.

New development, age anddisease have caused ourlegacy to deteriorate. The

system of beautiful streets is injeopardy. This manual calls for re-creating and expanding the legacyto meet tomorrow’s needs. Thedesign of streets contributes great-ly to the beauty and liveability ofour city. As redevelopmentchanges older parts of the city, thelegacy must be renewed.

Residential streets are those wherea predominance of the uses areresidential, whether single ormulti-family. These guidelines areintended to reestablish the tradi-tional beauty of Denver’s residen-tial neighborhoods. Replacing street amenities where lost and

extending them consistently intonew neighborhoods are the high-est objectives of this manual.

Commercial streets are thosewhere the predominance of usesare business, retail, or office.Good streetscape design will alsoimprove the image of a commer-cial district by unifying paving,lighting, plantings and furnishings.A unified streetscape will give adistinctive character that sets thedistrict apart from others.

Most commercial districts suffer from a mix of building styles,pavements, signs and other ele-ments. Sometimes these changesare so disruptive that the arealooks chaotic and no longer pre-sents a good image to the cus-tomer. When this happens, a new

streetscape can do a lot to restorethe image of a comfortable,healthy area offering with qualitygoods and services. A more com-petitive district and new customers often follow a new streetscapedevelopment.

Many elements work together tocreate a successful streetscape.Street trees, sidewalks, lighting,comfortable seating, easy to readsigns, convenient parking andother amenities tell the customerthat the owners care about them.A good design organizes these ele-ments to give drivers a view ofshops and to create a pleasant,safe zone for pedestrians, wherepeople notice the businessesinstead of the traffic. When street-scaping is successful, a new senseof pride is evident.

The purpose of this manual isto make the city’s guidelinesfor the design of streets

clear. If this purpose is fulfilled,Denver will become a more desir-able, liveable city for residents,business people, shoppers andvisitors.

WHO SHOULD USE THIS MANUAL

Property owners, developers, busi-ness people, merchants, designersand city staff are charged withapplying this manual to all designand construction efforts in thepublic right-of-way. Every newimprovement should comply withor respond to these guidelinesappropriately. Not covered hereare roadway design and projectsthat are covered under separateguidelines or plans approved bythe Planning and CommunityDevelopment Office, includingregional commercial districts andother special locations such as the16th St. Mall.

The guidelines apply to the activi-ties of numerous city agenciesincluding the City Forester’s Office,the Parks and Recreation Depart-ment, the Planning and Communi-ty Development Office, the Trans-portation Division of the PublicWorks Department and to otheragencies such as The RegionalTransportation District, ColoradoDepartment of Transportation,Public Service Company, the Met-ropolitan Sanitation District andthe Denver Urban RenewalAuthority. Unified application ofthe guidelines will insure consis-tent streetscape design of futureprojects located within the publicright-of-way.

H O W T O U S E T H I S M A N U A L

This manual is a tool for expand-ing the legacy of beautiful streets

in Denver. It is not a plan forexpanding the parkway system,but it is important that each newproject or design effort considerthe role of the street in the overallsystem: Was the street once a park-way? Is it a through-street whichconnects neighborhoods, districts,destinations or parks? Does thestreet have any unusual character-istics, such as diagonal alignment?Are there existing streetscape ele-ments which should be reinforcedor patterns which should be con-tinued?

If the answer to any of these ques-tions is yes, the design effortshould be extended to define thebest solution for the entire lengthof the street in the district. In suchcases it is important to work close-ly with the Denver Planning andCommunity Development Officeand Transportation Division of thePublic Works Department prior tocommencing design.

This Manual gives owners guid-ance in the design and mainte-nance of streetscape improvementswithin the public right-of-way. It’sjurisdiction does not encompassimprovements within private prop-erty, but especially on commercialstreets should influence landscap-ing elements such as plants, streetfurniture, screens, and walls out-side the edge of the right-of-way.This manual also addresses the

character and scale of commercialbuildings and signage, sincebuildings in commercial districtsoften face the street adjacent to theright-of-way line. Thus, buildingdesigns significantly influence thequality and character of astreetscape.

It is important to determine ifother planning has been per-formed in the area prior to begin-ning new design. Neighborhood,commercial or historic districtplans may be in place, or goalsand objectives may have alreadybeen established. Generally speak-ing, projects within special districtsrequire review before a designreview committee, based uponestablished guidelines. Streetscapeprojects within historic districts oradjacent to landmarks must bereviewed before the Denver Land-mark Commission. These plansmay provide more detailed or spe-cific information about localimprovements, but the spirit ofbeauty and quality urban designidentified here should be appliedeverywhere. This document is afoundation for all streetscape pro-jects, whether or not they are with-in special districts. Its design andtechnical principles underliestreetscape design throughout thecity. Each project should examinelocal conditions and apply theguidelines within that context.Improvements to commercialstreets should occur in a coordinat-ed fashion involving all the ownerson a block or within the commer-cial district to create the most uni-fied image possible.

Trees give many benefits tothe city. They supply shade,buffer wind, sun and bad

views, help clean the air andreduce glare. Street trees are themost important tool for bufferingpeople from cars. They create apedestrian space, make the streetmore comfortable and providebeauty year-round. Without streettrees, pedestrians are exposed tothe sun and the car with littlesense of comfort. Street trees are amajor part of Denver’s pleasantneighborhoods.

On commercial streets, trees arethe most significant element thatmake streets attractive to shoppers.Without street trees, shoppers feelthe heat, glare, dust and pollutionof the roadway. With them, theharshness of a paved environmentis alleviated and pedestrians canenjoy the shade, beauty andamenity that is essential to a pleas-ant shopping experience. A formal,repetitive use of trees is recom-

mended to unify districts and create a continuous pedestrian scale suited to storefronts.

Design for street trees shouldrespond to the uses on the street.In residential streets, trees in tree-lawns are recommended. In mostareas, the same species should beplanted on a block. Differentspecies with similar characteristics,such as form and color may bealternated in a regular pattern to avoidover-use of one species. The loss ofelm trees in the city due to Dutch ElmDisease reflects the danger of exten-sive planting of a single species.

Many factors affect design in com-mercial streets, including the vol-ume of pedestrians, the size andorientation of sidewalks, the dis-tance from trees to buildings, thevisibility of facades and signs, andthe speed and volume of vehicles.

1. Trees should have the same characteristics on both sides of the street. If mixing species, alter-nate them in a regular pattern.

2. Plant only one species where an area is to be unified. Avoid random changes in species.

3. Select trees that will fit when they are mature. Narrow areas suggest a narrow tree and openareas suggest a wide one.

4. Where tree lawns do not exist, treegrates or pavers are recommended to protect tree roots and pedestrians. Ground covers may be considered in low traffic volume areas.

5. Use tree grates where pedestrian traffic volume is high.

6. Existing trees must be protected during construction. For projects where a number of existing trees need protection, develop a tree protection program and have it approved by the City Forester. Consult the City Forester prior to removing any trees from the right-of-way.

7. A permit is required from the City Forester prior to planting trees in the right-of-way

T r e e L o c a t i o n

Consider mature tree size beforeplanting so that trees have room togrow. Where signs, lights, over-head or underground utilities, utili-ty poles and fire hydrants wouldlimit mature tree size, adjustmentsin species or location should beconsidered to minimize excessivepruning.

1. Plant trees with regular spacingin straight rows to create a contin-uous street edge. Adjust spacingonly slightly for driveways and lights.

2. Locate trees in a straight linemidway between the curb anddetached walk even where the

width of the tree lawn varies.

3. Plant trees 30 to 45 feet on center for most species. Reduced spacing may be appropriatedepending on the space andspecies. Review special conditionswith the City Forester.

4. When replacing trees in anexisting row, select new trees ofsimilar characteristics to thosebeing replaced, including form,scale, texture and color.

5. Trees should not be plantedcloser than 30 feet from the curbface at intersections and street cor-ners within the corner triangle.Review with the Transportation

6. Within the Sight Triangle nonon-plant materials over 32 inchesor plant materials over 6 incheshigh are permitted except fordeciduous trees, traffic control andlighting devices (see diagram - Intersection SightDistance Parameters).

7. Maintain minimum sight triangleand corner triangle distances forsafe view of oncoming traffic andpedestrians.

8. Trees must not interfere withvisibility of traffic control devicesespecially at intersections. Reviewwith the Transportation Division todetermine specific requirements.

9. At alleys trees should not belocated closer than 10 feet fromthe projected alley property line.

10. Trees should be located a min-imum of 42 inches from the face ofcurb.

11. For commercial and residentialstreets the minimum distance fromstreet lights is 20 feet for mosttrees. Individual species and siteconditions may warrant a varianceif approved by the City Forester,streetlighting design- Transporta-tion Engineering and Public Ser-vice Company.

12. At all locations trees should beadjusted slightly to ensure the dri-ver’s visibility of regulatory signs.

13. Create a clear walking zonebetween trees and buildings. Indowntown 10 feet is minimum.Distances as low as 5 feet may bepossible where space is very limit-ed, however few tree species willbe appropriate in such a smallarea. Trees must be placed farenough away from buildings toallow them to grow without exces-sive pruning.

T r e e S i z e

Trees should be large enoughwhen planted to add substantialshade and to reach a height appro-priate to surrounding buildings. Atmature size, residential street treesshould form a continuous canopyto reinforce the street space andframe vistas.

1. Street trees in grates should be3 inch caliper, minimum, with highbranching where pedestrians willbe passing beneath the tree canopy.This size is recommended so that

adequate branching height isacheivable without severe pruning.

2. Trees in tree lawns should be 2inch caliper, minimum. Note thatunder the favorable conditions of atree lawn, this smaller size tree maysoon catch up to the growth rate ofa larger tree planted in a grate.

3. The branching height of maturetrees on the traffic side of thestreet should be no less than 13feet 6 inches above the street.

4. The branching height of maturetrees on the pedestrian side of thestreet should be no less than 8 feetabove the sidewalk.

5. Small varieties of thornless andfruitless trees may be used only inmedian areas or traffic islandswhere lower branching habit willnot interfere with pedestrians,vehicles or driver visibility.

6. Trees within the small streettree category should only be usedwhere power lines overheadwould not allow a large street treeto reach maturity without severepruning.

All trees should fit the microclimate,soils, sun, moisture, budget and main-tenance environment in which theyare planted. This is a major concernin areas with high levels of pollution,salt, snow storage or automobile andpedestrian damage. Trees selected forurban streets should be able toendure pollution, compacted soils,minimal water, and low maintenance.

1. Trees near walks should bethornless and fruitless to minimizemaintenance and to reduce pedes-trian hazards. They must be strongwooded, resistant to most diseasesand insects, single trunked, withupright growth and a medium tolong life expectancy. Branchesshould resist breaking.

2. Trees and irrigation techniquesthat require minimal water shouldbe considered. Irrigation must beinstalled for street trees in all com-mercial streets. Irrigation must bedesigned to deliver the appropriateamount of water to each tree withminimum waste. Easily adjustable,automatic irrigation controls arerecommended.

3. Along commercial streets, treesshould be selected that will mini-mize the obstruction of views toretail signs. Employ trees withappropriate forms and character.Utilize tree spacing which supportsthis concept.

B. RECOMMENDEDSTREET TREES

Denver’s unique climate and soilslimit the variety of species whichare recommended for street treeplanting. These species best meetthe selection and size guidelinesfor most conditions and are pre-ferred for their dependability, lowmaintenance and drought resis-tance. Watering habits and soilconditions significantly affect theroot structure. The City Forestermay consider other species wherespecial conditions exist.

II. Groundcovers

Groundcovers, provide sea-sonal color, direct circula-tion and serve as a buffer

between people and cars. Groundcover plantings provide functionaland aesthetic benefits, howevermaintenance is extremely impor-tant.

A. Design

G u i d e l i n e s

Plantings other than trees in thestreetscape may include turf, groundcovers or shrubs. In commercialstreetscapes with a large areabetween the sidewalk and the streetor low pedestrian volume, a treelawn of grass may be most appropri-ate. This area helps soften the streetenvironment along the street edge.

1. Tree lawns, especially in newdevelopments, should be at least 8feet wide to accommodate irriga-

tion systems and to provide ade-quate room for healthy tree rootsystems. Turf should be provided

Brick Pavers may be used in place of very narrow tree lawns where irrigation isimpractical or in areas that receive high volumes of foot traffic.

Page 28: Streetscape Design Manual 1993 - Denver...Good streetscape design will also improve the image of a commer-cial district by unifying paving, lighting, plantings and furnishings. A unified

where the average width of the tree lawn is 8 feet or more. Smalllengths of step-out strips mayoccur within the 8 foot width.However, widths less than 4 feetshould be avoided. To water efficiently care must be taken,whether done by hand or by irrigated system.

2. For tree lawn areas less than 8feet wide, turf is difficult to irrigateefficiently and groundcovers orpaving may be considered.Groundcovers are preferred forwidths between 5 feet to 2 feet.Paving is preferred

where widths are less than 2 feetand in areas where heavy trafficand regular snow plowing occur.

3. For areas less than 30 squarefeet, special concern must begiven to the maintenance availableand groundcovers are the recom-mended material.

4. Tree lawns should be plantedwith sod or low groundcovers(below 6 inches mature height) inresidential areas and in commercialareas where pedestrian traffic doesnot warrant paving.

5. Very narrow tree lawns or thosein high traffic areas may be pavedwith brick, flagstone or concretepavers and/or colored or scoredconcrete. However patterned(stamped) concrete is not allowed.

6. Tree lawns should not be ele-vated above curbs except to pro-vide positive drainage. Whereplanters are used, the Transporta-tion Division requires that they beelevated a minimum of 2 feetabove top of curb, located so asnot to interfere with vehicle sightlines and located 30" minimumfrom the curb face.

7. Where the tree lawn area ispaved, a permeable paving systemshould be considered to enhancethe survivability of street trees.

B. Recommended Groundcovers

These plants are recommendedbecause they require moderate tolow amounts of water and haveproven to be successful in Denver.Others may work in special condi-tions but the City Forester shouldbe consulted.

Specific site conditions must befully understood prior to plantselection. Local microclimates andsoils are key factors that determinewhich plants will thrive. Wherepossible, low water-requiringplants should be selected. Treesand shrubs will require less waterand will thrive better if placed inplanting beds rather than turfareas. Water-loving plants shouldbe used in naturally moist areasand should be irrigated separatelyor provided run-off water to mini-mize irrigation needs.

The City and County of Denver iscommitted to the reduction ofwater consumption in landscapeirrigation and encourages theapplication of Xeriscape designand maintenance principles.

Recommended Turfgrasses

Turf should be planted on pre-pared soil from seed or sod. Seed-ing allows a greater turf selectionbut requires approximately sixmonths and regular maintenanceto become established. Newlyseeded areas require protectionfrom pedestrians and must be keptmoist until the seeds germinate.Sod creates an immediate effectbut requires high amounts of wateruntil established. All irrigated turfareas require organic soil amend-ments at the rate of at least 3 cubicyards per 1000 square feet.

Alternatives to bluegrass are rec-ommended and should be utilizedin all areas not prone to highpedestrian traffic. As alternativespecies are developed, water-con-serving sod or seed should beused. For recommended varieties,contact the Colorado State Univer-sity Extension Turfgrass Specialist.

MIXED FINE FESCUE, RYE-GRASS, AND BLUEGRASS.This mix works in sun and shade,suits a number of climate and soilconditions and provides improvedshade, disease, salt and moisturestress tolerance over pure blue-grass. Most commonly planted asseed mixed to specific site condi-tions.

TALL FESCUE - TURF TYPEDeep green color, shade and salttolerant, and drought resistantbecause of its deep root system.Currently available as sod bothwith netting and without. Includeat least three improved varieties ofturf-type tall fescue in the blend.

KENTUCKY BLUEGRASSBluegrass varieties and blends arenot generally recommend due totheir high water needs. Bluegrassis appropriate only in areas whichreceive extensive foot traffic.Blends including three or morevarieties improve disease resistance.

Recommended Groundcovers

Where ground covers are used, theintent should be to create a consis-tent carpet of plant material similarto the affect achieved by turf.

Mixed uses of species which createa planting display are not desirableexcept at planted corners on resi-dential streets. Ground covers pro-vide more seasonal variety, requireless water and, once established,usually require lower maintenancethan most turf species. For groundcovers to be successful, they mustcreate a tight, dense planting.

Groundcovers are not as depend-able as turf when required to growwith poor soil preparation andmaintenance and should only beplanted in areas which will receiveminimal foot traffic. They.requireadequate water and weeding untilestablished.

The species listed are preferred fortheir dependability, low mainte-nance and drought resistanceunless otherwise noted. Otherspecies may be allowed by theCity Forester; however, their useshould be limited to small areaswith special needs.

III. LIGHTING

Lighting can play an importantrole in the character, functionand security of a streetscape.

Scale, style, lighting effect, costand maintenance affect fixtureselection. Street lighting is ownedand maintained by Public ServiceCompany and is subject to theirrequirements as well as those ofthe City of Denver.

A. Pedestrian-Lighting

Pedestrian lighting consists of fix-tures less than 14 feet high and isnot provided by Public ServiceCompany. It is generally not rec-ommended in front of residencesexcept at bus stops or where acomprehensive neighborhood ordistrict plan calls for it. Variousprograms in the city may providepedestrian lighting through a grantto a neighborhood association. Call the Office of Planning andCommunity Development for moreinformation.

Pedestrian-scaled light posts andluminaires play a vital role indeveloping the unique character of commercial districts throughoutthe city. Pedestrian lights illumi-nate the sidewalk and provide afeeling of security at night. Fixturesshould relate to the image and his-tory of the individual area and tofixtures in similar districts in thecity.

S p a c i n g a n d L o c a t i o n

Locate lights as part of an overallsystem that organizes other streetelements such as trees, benches,and paving.

1. Place lights at least 2 1/2 feetfrom the back of the curb to allowroom for car bumpers and doorswings. Align with street treeswhere possible.

2. Place lights at least 5 feet from

the edge of the curb transitionpoint nearest the driveway, curbcut or alley and at least 20 feetfrom the extended flow line of thenearest intersection. (See diagram, page 43)

3. Space lights at least 50 feetapart. 60-115 feet is preferable inmost cases to provide a pleasingeffect and to ensure room forstreet trees and other furnishings.Closer spacing can also causeuncomfortable glare.

4. Install luminaires a maximum of14 feet and a minimum of 12 feetabove sidewalks to avoid glareinto upper windows. Avoid placinglights directly in front of residencesto avoid disturbing inhabitants.

S t y l e a n d M a t e r i a l s

Select lighting styles to integratewith the architectural or historicalcharacter of the area.

1. Acorn type luminaires are rec-ommended for most commercialstreets in order to maintain consis-tency throughout the city. Avoidselecting different types of lightingfor small projects.

2. Globe type luminaires arereserved for parks and parkwaysexclusively.

3. Poles should be well articulatedwith enough detail to create a range ofscale for the pedestrian whether nearor far away. Flutes, mouldings or othertraditional details are strongly preferred.

4. Alternative fixtures that reflectlocal architectural or historicalcharacter are subject to approvalby the Planning and CommunityDevelopment Office and theTransportation Division.

5. Single luminaires are highly pre-ferred over multiples, whichshould be considered only for spe-cial locations such as gateways orentry points of a district.

6. Pole and base colors are to beeither black or ‘federal green’ (fed-eral color specification #14056).

7. Luminaires are to be translucentor glare-free, utilizing obscureglass or acrylic lenses.

8. Luminaires used in single ormultiple pedestrian light fixturesare to use 50 watt high-pressuresodium lamps to provide consis-tent light color and intensity levelscitywide. An 18 watt compact floures-cent lamp is an option where a whiterlight color is architecturally desirable.

9. Multiple luminaires should notbe more than 50 watts in eachluminaire.

B. Street Lighting

Streetlighting plays an important rolein the quality and safety of streets,especially at night. Lighting illumina-tion levels are based on two criteria:the uses along the street (such ascommercial or residential) and thevolume of automobile traffic. TheCity of Denver and Public ServiceCompany have guidelines for spac-

ing, location, style andcolor. Once a site planhas been developedincluding street trees,pedestrian lighting andfurnishings, the planshould be submitted firstto the City of Denverand then to PSCo forstreet lighting input.PSCo review shouldinclude transformer, cab-inet and meter locations.For questions regardingspecific design issuessuch as pole spacingand wattage contact thecity’s streetlightingdesign engineer. Forquestions regarding per-mits, fees and billing,contact the city’s street-lighting administrativeengineer (see Agency

Summary).

S p a c i n g a n d L o c a t i o n

Locate street lights as part of anoverall system including cabinets,transformers etc.

1. Place lights at least 2 1/2 feetfrom the face of the curb to allowroom for car bumpers and doorswings.

2. Place lights at least 5 feet fromthe edge of the curb transitionpoint nearest the driveway, curbcut or alley. At signalized intersec-tions, lights are generally mountedon the signal poles. Where signalsdon’t occur, locate lights near theintersection.

3. Spacing for commercial streetswill range from 100 to 150 feet.For residential streets 150 to 170

feet is appropriate and for specialdistricts such as downtown consultthe City of Denver street lightingdesign engineer (see Agency Sum-mary).

C. Special Effect Lighting

Special effect lighting may includestring lighting in trees or uplight-ing in the tree grate or plantingbed. If string lighting is desired,electrical outlets should be includ-ed adjacent to each street tree.

If uplighting is desired aroundtrees, tree grates should be usedwith cut-outs for the light. Uplight-ing should be selected to blendwith plantings, be waterproof anddirectional. Up lighting should usefixtures which shield the lightsource from passing motorists.

IV. Paving

Paving is an important unify-ing element in streetscapedesign. Paving patterns can

guide movement, define spacesand provide variety. When design-ing a pedestrian area paving pat-terns, colors and textures shouldbe complementary to surroundingelements. Well-designed pavingcreates order, scale and identity onthe street. Once established, thepaving pattern should become theorganizing framework for furnish-ings, trees and plantings.

A. Sidewalks

Sidewalks give pedestrians accessalong streets. Sidewalks in Denverneighborhoods have traditionallybeen detached from the curb. Thisprovides the tree lawn and roomfor street trees close to the curb.The detached sidewalk is stronglypreferred in all Denver neighbor-hoods because it enhances thebeauty, safety and shared commonspace in the neighborhood.

Concrete is the preferred material,although interlocking concrete unit

paving, flagstone and brick pavingmay be acceptable in neighbor-hoods where these materials areprevalent. Special paving in treelawns is recommended in residen-tial streets only where pedestrianuse is heavy and tree lawns cannotsupport turf or ground covers.

S i d e w a l k G u i d e l i n e s

Paving is the best way to unify thestreet. Over-designed patterns maybecome chaotic or dated. Patternand color should be subdued andavoid sharp contrasts with sur-rounding paving. Pattern shouldrelate to the size and shape of thespace and should create a sense oforder in the placement of otherstreet furnishings and plant materals.

1. Maintain a clear unobstructedpedestrian path. In downtownDenver, 10 feet width is required.In other areas 10 feet width isdesired but as little as 5 feet maybe allowed in constrained loca-tions. A 5 foot width is the mini-mum for residential areas.

2. Detached sidewalks shouldinclude a tree lawn of 8 feet mini-mum, planted with trees andgroundcover or sod. Wheregroundcover or sod is not practi-cal, as in retail streets, tree gratessurrounded by a hard surface ofpavers or concrete are appropriate.

S i d e w a l k P a v e m e n t s

1. Concrete including plain grey,integral colored concrete and spe-cial finishes is acceptable (exclud-ing stamped concrete, seeded con-crete or epoxy concrete). Concreteshould be a minimum of 4 inchesthick, meeting industry standardsfor concrete mix, finishing, curingand sealing.

2. Care should be taken whenusing integral pigmented coloredconcrete. Select subdued andearthtone colors which will com-plement natural materials. A goodexample is “Sunset Rose” (1 lb of No. 160 per bag of cement), manu-

factured by the Frank D. DavisCompany. Rich or bright colorswill draw more attention thandesired.

3. Use only paving bricks specifi-cally designed for sidewalk useaccording to industry standards.Brick pavers must be set on a con-crete slab with mortar joints andnot on a sand base.

4. Interlocking concrete pavers,are a durable choice. Set on a sandbase with tight sand joints accordingto manufacturers recommendations.

5. Flagstone pavers are recom-mended in historic areas wherethey originally existed. Installationmay be on a sand base with sand joints or on a concrete base withmortar joints as approved by theDepartment of Public Works.

6. Precast concrete pavers may beinstalled using finish and colorguidelines as discussed under con-crete pavement above. Thesepavers may be installed on a sandbase or on a concrete slab withmortar joints.

7. Once installed, all pedestrianwalks must be safe for pedestrianswith no gaps or joints larger than1/4 inch.

B. Amenity Zone

The amenity zone is a paved areaalong the back of the curb in a com-mercial streetscape that organizestrees, plantings, furnishings andlighting. It may range from 4 to 12feet wide. Ample clear space mustbe provided between the amenityzone and building facades on thesidewalk for pedestrian circulation.

1. Maintain an 8 to 10 foot widepedestrian zone or unobstructedopen walkway.

2. The amenity zone may be asnarrow as 4 feet without trees or 5feet with trees, however widerdimensions are strongly recom-mended.

3. The amenity zone may be nar-rowed or relocated to accommo-date outdoor uses associated withindividual businesses such as side-walk cafes.

C. Curb Ramp and Curb Cut Guidelines

The construction and reconstruc-tion of all sidewalks in the city

should include curb ramps at allintersection corners to enable thesafe and convenient movement ofall pedestrians. Curb ramps shouldalign with curb ramp locationsacross the street. Ramps located atthe 45 degree point of the curveare the least desirable because ofthe potential danger to pedestriansand bicyclists.

Curb ramps are required anywherethe sidewalk crosses a curb. Indowntown a “walk-over” type ofcurb is standard. Trough-typeramps are recommended else-where in the city. Any deviationfrom the city standards must beapproved by the Department ofPublic Works prior to construction.See Denver Street DevelopmentStandards and consult with Trans-portation Design Engineering.

D. Crosswalk Pavements

Crosswalks are generally paintedat signalized intersections in mostareas of the city. In commercialareas the crosswalk materials andpattern can be an important unify-ing feature of the district.

G u i d e l i n e s

Within a district it is important totreat each street intersection thesame in terms of size of curbradius, location and type of curbramps, signage location andpaving within crosswalks. Cross-walk pavement should contrastwith the adjacent street pavementthrough color or texture. Driversneed to know where to stop orlook for pedestrians and pedestri-ans need to know where they canrely on crossing the street safely.

Even if the crosswalk is distin-guished in terms of color and tex-ture, it is still necessary to install“stop bars” using paint or vinylstreet marking material as deter-mined by the Transportation Divi-sion.

33

Trees, lights, and furnishings are located in the Amenity Zone which separates pedestrianand store front uses from vehicles.

Trough type curb cut ramp. The curb “returns” up the ramp which provides orientation forthe visually impaired.

R e c o m m e n d e d C r o s s w a l k P a v i n g

Contact the Transportation Divi-sion for additional information oncrosswalk paving and striping.

1. Painted lines on the street arethe most inexpensive solution andare the most visible marking.

2. Concrete paving can be used asa contrasting material in asphaltstreets but it must be augmentedby painted or vinyl stop bars.Stamped concrete is prohibited.

3. Unit pavers and brick paverscan be used with cautions. Theyare expensive, the contrastbetween paver and asphalt maynot be sufficient and painted stopbars are a necessary minimum.

E. Entry Walks

Entry walks are those walks whichextend out from the home and/ordetached sidewalk and lead to thecurb. They are appropriate in thetree lawn where there is a func-tional need for them. Two or 3feet are recommended widths,with a maximum of 5 feet allowed.They may be used in conjunctionwith step-out strips as a way of giving access from parked/stopped

vehicles to the sidewalk. Concreteis the preferred material, althoughinterlocking concrete unit paving,flagstone and brick paving areacceptable in neighborhoodswhere these materials are prevalent.

F. Step-Out Strips

“Step-out-strips,” or landing walks,are recommended as a way tofacilitate access to cars while main-taining the integrity of the treelawn. Step out strips are a 12-24inch wide area of paving next tothe curb, connected to the side-walk by an entry walk. Historical-ly, step out strips were short inlength and had to serve only onecarriage or car. Today it may makesense to install a longer versionperhaps running the entire lengthof curb in front of a property.

The design intent for step-out-strips should be to minimize thedisruption within the continuoustree lawn. Where possible theyshould be designed to be incon-spicuous. Plain concrete paving,brick paving, interlocking concreteunit paving, and flagstone areacceptable materials. Installing astep-out strip requires a construc-tion permit from the Solid WasteManagement Section, Neighbor-hood Support Services.

G. Splash Strips

Splash strips are typically a 12 to 18inches wide paving along the back ofthe curb. They protect the median ortree lawn landscaping from sand andsalt used on the roadway. They aremost appropriate where streets haveno parking lane and heavy auto trafficoccurs adjacent to the curb. Theyshould be installed in continuous sec-tions for a uniform appearance and performance. (See page 32)

H. Paving Not Recommended

1. Stamped concrete is not permit-ted on sidewalks or elsewhere inpublic rights-of-way because ofappearance, difficulty of snowremoval, poor durability and futurerepair difficulties. Patterned pavingin tree lawns is not recommendedbecause it visually calls attention toan area that should not be a focus.

2. Seeded concrete and epoxyconcrete are not acceptablebecause of appearance, poor dura-bility and future maintenanceproblems.

3. Any glazed product or smooth,slippery surface product shouldnot be used in pedestrian trafficareas for pedestrian safety.

4. Any thinset material should notbe used because of future mainte-nance problems.

5. Any clay brick product otherthan paving brick should not beused because it may be difficult tomaintain and the product’s resis-tance to freeze-thaw damage maynot be adequate.

6. Any material that is so texturedor patterned that it may cause atripping hazard, should not beused

V. FURNISHINGS

Street furnishings such as seat-ing, newspaper racks, bicycleracks, bollards and trash

receptacles are important function-al elements and amenities, espe-cially in the commercial street-scape. They should be designedto be attractive and unified withinany given district.

Maintenance, safety and comfortare primary considerations in thedesign and placement of street fur-nishings. All furnishings placed inthe right-of-way should be of highquality, designed for outdoor useand require minimum maintnance.

In general, street furnishingsshould be located at least 2 1/2feet from the curb face where on-

street parking occurs, and 3 1/2feet where travel lanes adjoin thecurb.

Street furnishings require a revoca-ble permit issued through theDepartment of Public Works,Right-of-way Engineers

A. Neighborhood Entry Monuments

Distinct, identifiable neighbor-hoods may desire to have monu-ments placed at key points ofentry or at the center of the neigh-borhood. Entry monuments can bea source of pride for residents andgive identity to the neighborhood.

G u i d e l i n e s

Entry monuments should onlyoccur where a distinguishableentry along a street already occurs.In some neighborhoods clearpoints of entry are difficult to findyet identity monuments at keylocations may be appropriate tohelp create a sense of place and toreinforce the neighborhood identi-ty. Monuments should reinforcethe character appropriate to theneighborhood

1. Entry monuments should beintegrated into a total design oftypical elements such as trees,ornamental lighting, paving pat-terns, median planting, walks andbuildings.

2. The scale, character, shape,materials and location of entrymonuments must be planned andconsistent for an entire neighbor-hood. This does not mean that allentries should have monuments. Iftoo many are placed or if theyoccur in inappropriate locations,the strength of the entry will bediminished. Ad-hoc placement anddesign of entry monuments is notacceptable. Contact the Office ofPlanning and Community Develop-ment for more information.

3. Provisions must be made for themaintenance of entry monuments.The most effective way to addresstheir maintenance is to have aneighborhood association commit-ted to their upkeep. If this is notfeasible, it may be possible to havethem added to a list of similar mis-cellaneous improvements that arethe responsibility of the Depart-ment of Public Works. Their designshould be as durable and mainte-nance-free as possible. All monu-ments must be approved by theDepartment of Public Works priorto construction.

4. Appropriate scale and propor-tion are critical to the sense ofarrival and entry. Monuments mustbe effective at the pedestrian andvehicular scale. A range of scaleswill also create a sense of move-ment at the point of entry. Monu-ments must be located a certaindistance away from a street intersec-tion. Contact the Traffic EngineeringDivision for more information.

5. Monument design shouldembody elements of form anddetail which represent and identifythe neighborhood. The monumentshould make a reference to thecharacter of the shared vision ofthe district which it serves.

6. All entry monuments should fitcomfortably into the family ofexisting gateway monuments inDenver.

B. Commercial District Gateway Markers

Gateway markers may be used todefine a commercial district. Theyare recommended only where acoordinated district plan includesmarkers as an important elementto be unified with the overall dis-trict design.

G u i d e l i n e s

The site and surrounding elementsof markers are important. Lighting,planting and signs related to themarkers should be carefullydesigned to reinforce the gateway.The design of the markers shouldbe coordinated with the materialsand details of other elements inthe district and should embody thecharacteristics that identify the area.

1. Scale and proportion are criticalto the design of the gateway. Thescale of the markers should relateto street width and the size ofbuildings nearby and must beeffective at the pedestrian andvehicular scale, meaning they mustbe attractive and interesting fromthe street and the sidewalk.

2. Entry markers must not interferewith driver sight-lines at corners.Contact the Transportation Divi-sion for detailed requirements.

3. Some districts may have a pri-mary gateway and secondarypoints of entry. A hierarchy ofgateways should be developed ifsecondary entries are to receivemarkers.

C. Walls and Screens

Walls and screens may be includedin a streetscape to direct or screena view or to provide changes ofgrade. The height and materialselected should relate to buildingarchitecture and the character ofthe district. Walls and screens canbe important in creating a continu-ous sidewalk edge that unifies thestreet space.

Call the Zoning Administration andthe Office of Planning and Com-munity Development for informa-tion regarding parking lot screens.

D. Seating

Seating may be provided whenspace allows for a clear pedestrianwalking zone and separate seatingareas. Seating expands opportuni-ties for people to use the street,especially in commercialstreetscapes. Seating may be pro-vided by benches, planter walls,edges, steps, or moveable chairs.

G u i d e l i n e s

1. Seating surfaces should be 16 to18 inches high and should have aminimum depth of 16 inches forseats without backs, 14 inches forseats with backs.

2. Walls, ledges and steps that areavailable for seating should bebetween 12 and 20 inches highand 16 inches wide wherever pos-sible. Walls used for seating onboth sides should be a minimumof 30 inches wide.

3. Seating should be durable and

comfortable. Avoid sharp edges and poorly designed or fabricated fur-niture. Metal is the preferred material.

4. Seating design should comple-ment the style of the surroundingarchitecture and other furnishings.

5. Except for moveable chairs,seating should be secured perma-nently to paved surfaces for safetyand to avoid vandalism.

6. Seating should not interferewith plant materials or pedestriancirculation and should be placedfor psychological comfort.

7. Comfortable seating should pro-vide a sense of having protectionfrom behind and something inter-esting to look at such as shop-fronts or other pedestrians.

8. Seating adjacent to where bicy-cling is permitted on sidewalks orother bike paths must have a mini-mum 3 foot clearance from thebicycle path.

37

Walls can be used to accommodatechanges in grade.

A durable steel screen is located so that itcontinues the line formed by the face ofthe building which defines the pedestrian

walkway.

Made of durable, heavy gauge steel the “Bowery” style bench is recommended for moststreetscape projects.

E. Tree Grates

Tree grates are an attractive way toprotect trees planted in pavedareas. Other options such as mod-ular blocks, brick pavers, flag-stone (in historic areas) andground covers may be used uponapproval of the TransportationDivision and the City Forester.

G u i d e l i n e s

Tree grates are the recommendedmethod for tree planting in pavedareas.

1. Open tree grates should be atleast 5 feet by 5 feet with openingsno more than 1/4 inch in width.The size and shape of tree gratesshould relate to the paving pattern.They should be designed to allowfor tree trunk growth, constructedof ductile iron, and unpainted orpainted a dark color with adurable, factory applied finish.

2. Irrigation systems within gratesare preferred but dry wells may beallowed with written maintenanceagreements from the owners. Theirrigation system should be on azone separate from all other land-scape zones and should bereviewed with the City Forester.

3. If string lights are anticipated inthe trees, electrical outlets shouldbe provided in the tree grate area.If uplighting is desired, select a treegrate manufactured to support the light.

F. Fencing and Railings

Fencing within a commercialstreetscape can be provided toenhance a neighborhood charac-teristic while in residential districtsit helps create a definition of thefront yard. Railings may be neces-sary as a safety feature or as afunctional support rail (leaningrail) for people to lean against.Railings and fences can helpdefine the street space.

G u i d e l i n e s

Fences and railings should have anornamental character as well asutilitarian function. Where railingsor fences in a particular neighbor-hood or district contribute to theoverall image of the area, try touse the same or similar designdetails to reinforce that character.

1. Fences and railings must notinterfere with pedestrian safetyby blocking access from thestreet to the sidewalk.

2. In certain situations a railingis required to protect the publicagainst potentially hazardousgrade changes. Pedestrian safetyrailings at grade changes shallbe a minimum of 42 incheshigh. They must have intermedi-ate rails, balusters, ornamentalor patterned infill. For moreinformation contact Design orTransportation Engineering,Department of Public Works.

3. Fences and railings should be between 32 inches and 48 inches tall except railings on bike rampswhich must be 54 inches tall tomeet AASHTO standards.

4. Where desired, place leaningrails at or near bus stops, placeswhere shoppers are picked up ordropped off, and places wherepeople are likely to stop or waitwithout necessarily wanting to sit.Leaning rails should be between27 and 42 inches in height.

5. A 2 to 3 inch high curb placed 4inches in front of a railing will pre-vent the footrest of wheelchairs orother wheeled vehicles from strik-ing the railing’s vertical supports.

6. Railings must be designed tosupport loads in both the horizon-tal and vertical directions of 50pounds per linear foot. Fasten rail-ings securely.

G. Trash Receptacles

Trash receptacles should be easilyaccessible for pedestrians andtrash collection. Their designshould relate to other site furnish-ings as well as building architec-ture. They must be carefullyplaced to be unobtrusive yet effec-tive. On paths where bicycling ispermitted, maintain a 3 foot set-back from the edge of bike path.

G u i d e l i n e s

Trash receptacles should bedesigned to fit anticipated use andfrequency of maintenance. Theyshould be firmly attached to pavingto avoid vandalism. Covered topsand sealed bottoms should beincluded to keep the contents dryand out of sight at all times.

Trash receptacles should bedesigned in two pieces. The innercontainer should ensure easy trashpickup and removal and an outershell should blend aestheticallywith the other streetscape ele-ments. They should be convenient-ly placed near benches, bus stopsand other activity nodes, andarranged with other streetscapeelements into functional composi-tions. They should not be placeddirectly adjacent to benches.

H. Bollards

Bollards are generally used to cre-ate a low barrier that separates autoand pedestrian traffic, highlight andprotect a special feature, emphasizethe historical character of the areaor direct circulation patterns.

G u i d e l i n e s

Select a bollard design that isarchitecturally and aestheticallyappropriate to the area and otherstreetscape elements. Bollards canbe used to provide low-level light-ing to pedestrian paths.

1. Bollards should be between 28and 42 inches high.

2. Bollards should be set 2 1/2 feetminimum clearance from curb face.

3. Clearance between bollards orbetween bollard and any otherstructure or pole must be at least36 inches. Clearance must be atleast 60 inches where there isclearly one primary path.

4. Bollards may be chained or cabledtogether if provided with attachmentsas an integral part of the design.

5. Standard pipe filled with con-crete is not acceptable in pedestri-an locations.

6. Utilize removable bollardswhere service vehicles need peri-odic access.

I. Planting Pots and Planters

Planting pots provide an addeddimension and color to street-scape planting. They also directpedestrian traffic, create focalpoints and provide pedestrian rest-ing areas. Large pots are preferredinstead of fixed planter boxesbecause of potential conflicts withvehicles and maintenance.

G u i d e l i n e s

1. Planting pots should be plantedwith annual flowers or withground covers. Pots should occupya surface area of at least foursquare feet and should not blockother elements such as streets,signs, meters, or street lights,

2. If planter boxes are used, treesor any woody shrubs should notbe planted in them. Their survivalrate is generally very low becausethe roots often freeze in the win-ter. Only annual flowers or ground-covers should be planted in boxes.

Planters that are to be used forseating should be between 12 and20 inches in height with a rim of atleast 8 inches in width, wider ifseating is intended on the edge.Plant materials should not interferewith the seating. Provisions mustbe made for ensuring adequatewatering and drainage. Staining ofpaving from planter drains shouldbe considered in planter location.

J. Newspaper Racks

Appropriately designed newspaperracks should serve the public with-out compromising pedestrian circula-tion and the appearance of the street.

G u i d e l i n e s

1. Cluster newspaper racks togeth-er wherever possible. Screeningshould also be considered to mini-mize views of the racks from thestreet. Arrange racks with otherelements to create an organizedstreetscape.

2. Racks should be painted a neu-tral background color so that theydo not stand out.

3. Racks should be placed at least2 1/2 feet from the curb face mak-ing sure that there is adequatewidth on the sidewalk betweenracks and adjacent buildings. Ifpossible, place racks against thebuilding wall and leave the rest ofthe sidewalk clear for pedestrians.

4. Racks should be placed as closeas possible to pedestrian activitynodes. They shall not be locatedwhere they will obstruct the viewof drivers at intersections or blockviews of business displays orsigns.

K. Bicycle Racks

Bicycle racks should be providedwithin commercial streetscapes toencourage bicycle use.

G u i d e l i n e s

1. Avoid placing bicycle racks inareas where they may endangerthe safety of pedestrians orcyclists.

2. Select racks that are permanent-ly mounted structures, designed ina simple style, and easy to use.The rack must allow both theframe and at least one wheel to belocked. Racks that allow for thelocking of only one wheel are notacceptable.

3. Place bicycle racks where theyare near entrances or gatheringplaces. Avoid placement that cre-ates a tripping hazard. If possible,place the racks where the parkedbicycles will be visible from insidethe adjacent building. Ideally, bicy-cle parking should be more conve-nient than automobile parking

L. Kiosks

Kiosks are intended to serve asinformational points, to directpedestrian traffic and to organizeoutdoor spaces. They should beused sparingly and only whenneeded to impart community infor-mation.

G u i d e l i n e s

Kiosks should be carefully posi-tioned in conjunction with otherelements of street furniture such asbenches, lighting, and landscaping.They should be focal points inopen areas, and may be combinedwith other elements like businessdirectories, telephones, mailboxesand newspaper racks. The designshould be compatible with andcomplementary to the surroundingarchitecture and other furnishings.

1. Kiosks should facilitate the post-ing of notices and their removaland cleaning.

2. Kiosks should be easily accessi-ble from all sides and adequatelyilluminated.

3. Kiosk designs require review bythe Denver Planning and Commu-nity Development Office.

4. Kiosks should be designed sothey are easy to maintain.

M. Fountains

A fountain provides moving waterthat masks noise, cools andhumidifies the air, increasing com-fort and beauty in a space. Foun-tains can also be used to definespace or provide an interestingfocal point.

G u i d e l i n e s

1. The rim around the fountain orpool should be between 12 and 20inches in height and 16 inches inwidth if used for seating.

2. Fountain design should respondto wind direction, building loca-tion, pedestrian circulation, poten-tial ice build-up in winter and theappearance of the fountain and itsbasin when not operating.

3. Fountains should include arecirculating pump for conserva-tion purposes.

4. Maintenance is crucial to thesuccess of all fountains. The ownershould be committed to mainte-nance prior to beginning design.

N. Mailboxes

Mailboxes are placed by the U.S.Postal Service. Their locationshould be coordinated with thePostal Service during design tominimize clutter.

O. Parking Meters

The location of parking stalls andmeters should be coordinated tominimize clutter. Meters should bealigned with other furnishingswhere possible. Alternate paintcolor and base covers for meterpoles can improve the appearanceof standard meters. They should belocated 18 inches behind the curb,22 feet on center, one per stall.Contact the Parking ManagementDivision for more information.

P. Utility Boxes, Meters and Manholes

Coordinate the location of all pro-posed utility boxes and meters,including irrigation controls, withthe proposed locations of site fur-nishings, trees, signs and lighting.Boxes and meters should be locat-ed 2 1/2 feet from the curb faceand should not interfere withpedestrian movement

There are several kinds of utilitycabinets that may need to beaccommodated, including cabinetsfor electric meters, water meters,water/irrigation controllers, back-flow preventers, traffic signalswitching equipment, and PublicService Company switching gearand transformers.

G u i d e l i n e s

1. Utilities should not be locatedunder walkways or where they mightinterfere with or preclude street trees.

2. Traffic signal switching gearcabinets are of a standard design.They must be located near the sig-nals they control, with care not toblock pedestrian access at thestreet corner.

3. Electric meters, water metersand irrigation controllers can behandled individually or consolidat-ed into one cabinet. Public ServiceCompany transformer vaults and

switch cabinets are larger andshould be located as inconspicu-ously as possible.

4. Any cabinet must be accessible,with room to swing the doorsopen and space to get the neces-sary equipment in position for ser-vice. Check with the appropriateutility for specific access require-ments.

5. Before finalizing the design ofany streetscape improvements,existing overhead and under-ground utilities should be locatedand sized with the assistance ofthe various city departments. Con-tact the following for more infor-mation: Public Service Company,U.S. West, cable television compa-nies, Water Department, andDepartment of Public Works SolidWaste and Wastewater Manage-ment Divisions.

Q. Bus Stops

Standard bus shelters are placedby the Regional TransportationDistrict (RTD) at stops where thereis a clear need. If a different typeof shelter is desired it must beapproved by RTD. Any additionalcosts and maintenance become theresponsibility of the adjacent prop-erty owner, maintenance district orbusiness improvement district.

Benches are not placed by RTDexcept as part of a shelter. Advertis-ing benches are placed by privatecompanies under a revocable per-mit. If a different type of bench isdesired or if a bench is desiredwhere RTD does not find a need,then the adjacent owner mustaccept costs and maintenance andapply for a revocable permit. Nei-ther the city nor RTD normallymakes funds available to purchaseor install benches. Call the Planningand Community DevelopmentOffice or RTD for more information.

R. Public Art

Public art should capture and rein-force the unique character of aplace. It can interpret the commu-nity by revealing its culture, historyor fantasy. Art that invites partici-pation and interaction, and thatadds local meaning is preferred.

The Mayor’s Office on Art, Culture and Film is responsible for adminis-tering the city’s Art in Public Placesprogram with the intent that 1% ofthe construction budgets of projectswith budgets over $1 million be uti-lized for the inclusion of art intothose projects. The Commissionholds selection processes for artistsand artworks for each project.

G u i d e l i n e s

Art should add beauty and interest. Itmay feature humor, water, seating,and opportunities for children toplay. The setting for public art is sig-nificant to the experience of the artitself. The place’s impact on the artmay be as great as the art’s impact onthe place. The two together enrichthe place and make it memorable.

1. When considering placement offreestanding pieces of art or sculp-ture, avoid locations where itwould compete with a storefrontor obstruct a pedestrian path, cre-ate a traffic hazard, or competewith another sculpture.

2. Murals or bas-relief may be usedto enliven otherwise blank walls.

3. Construct public art usingdurable materials and finishes suchas stone or metal.

VI. STREETSCAPE LAYOUT

There are many factors to con-sider in laying out astreetscape. Existing elements

such as curb cuts, trees, storefrontsand signage significantly influencethe final layout. The examplesshown are selected prototypical lay-outs that indicate common appropri-ate solutions to streetscape layout.Other layouts may fit a particularlocation more closely than these,however these should be used as abeginning point in design. Forexample, where uniform streetlight-ing is critical, such as on a commer-cial or arterial street, the uniformspacing of lights may be the deter-mining factor for where all the ele-ments are placed. The best layoutshould be a balance of existing con-straints and the uniform placementof new elements. The examplesillustrate the layouts for a typicaleast-west street with lots 125 feetdeep interrupted by a 16 foot widealley, and a north south street with a500 foot frontage.

VII. RESIDENTIALBUILDINGS

Residential buildings providethe edge of the perceivedpublic space and are there-

fore important to the character of

a neighborhood. Buildings whichfollow a consistent setback andwhich provide a consistent massand height along the edge of thestreet provide the most pleasing,unifying and traditional scale to aneighborhood. When combined

with well maintained front yards,tree lawns and street trees, individ-ual homes and buildings form thebackdrop of the street and con-tribute greatly to the neighborhoodcharacter which is so highly valuedin Denver.

VIII. COMMERCIALBUILDINGS

The building facade is an inte-gral part of the streetscape.In commercial districts they

should be well-designed, legiblestorefront designs that are comple-mentary to the entire area.

A. Character

Use architectural features whereverpossible to tie commercial buildingsinto a cohesive district. When possi-ble relate entries, window lines andsign bands to adjacent buildings.

Use materials that complement thearea’s character in terms of color,scale, and texture. Use patterns

that provide scale and interest andrelate to existing patterns in theneighborhood.

At the edges of neighborhoodcommercial districts, relate to theadjoining residential neighborhoodwith scale, detail and materials.

Avoid the use of reflective wallmaterials and glass that will gener-ate glare and heat, especially at thesidewalk level and near resi-dences. Transparent facadesencourage shopping and increasethe pedestrian’s sense of securityon the street.

B. Scale

Building scale contributes to ourperception of a place’s character.Create buildings that are pedestri-an in scale, that impart comfortand contain visual clues as to thesize of the building from close anddistant viewpoints.

Design buildings to be small-scale,and pedestrian-oriented at thestreet level. Use structural bays,expressed columns, window mul-lions, etc. to give the ground floorlevel “human” scale. Design largebuildings so that they appear smallin scale when seen from the side-walk. Avoid massive, monolithicfacades.

C. Continuity, Interest, and Comfort

If streets are to have activity, build-ings must be oriented to the street.Facades should provide a continuityof retail frontage along the sidewalk.When planning new buildings devel-op the ground level with as muchstreet-oriented retail or services aspossible.

Develop the ground level of build-ings to provide visual interest topedestrians. Outdoor dining areas,retail display windows or activitiesthat are visible from the streetaccomplish this. Create lively andinteresting facades for the enjoy-ment of pedestrians.

Retail shops at street level shouldhave direct access to and from thesidewalk. Avoid designs thatrequire entry from internal malls orlobbies, except for shops at theupper level.

Avoid split-level entrance schemes,as they reduce pedestrian activityon the street and create barriersbetween shoppers and displaywindows.

Building facades should closelyalign and create a continuousfacade, punctuated by storeentrances and windows. This pro-duces a comfortable sense ofenclosure for the pedestrian and acontinuous storefront that attractsand encourages thepedestrian to continuealong the street.

At least one of thehandicap accessibleroutes required by thebuilding code shouldbe the same as theprincipal publicentrance. If parking islocated at the rear orwithin the building,there should be twoaccessible routes, onefrom parking andanother in front. Allaccessible routesshould extend fromwithin the building tothe handicapped park-ing spaces or the pub-lic sidewalk withoutinterruption.

Corner buildings are

highly visible and require specialcare in their design to anchor adistrict, serve as landmarks and toprovide a sense of enclosure forthe intersection.

Use awnings or canopies to reduceglare on storefront glass and toshelter the pedestrian standingnear the storefront. Cantileverawnings and canopies from thebuilding face so as to keep thesidewalk as clear and unobstructedas possible. Care should be takento preserve views down the street.

If the building face cannot havewindows, the blank wall should betreated with decorative architectur-al finishes, screens, display cases,sculpture, murals, or plant materi-als to create an interesting walkingenvironment.

Treat all publicly visible facades ofa building equally in terms ofmaterials, colors, and designdetails. The building should have a‘finished’ appearance on all visiblesides.

IX. SIGNS

Signs include pri-vate business andpublic regulatory

signs. All signs installedon buildings or includ-ed in the public right-of-way must conformto the city Sign Code.A sign permit must beobtained from theBuilding InspectionDepartment prior toinstallation. Theseguidelines supplementthe Sign Code regard-ing the design andplacement of signs.

A. Business Signs

Signs are important to the successof most businesses. They identifythe business to the driver andpedestrian and, if well designed,can harmonize with the street andenhance the image of the district.

G u i d e l i n e s

Colors, materials, sizes, shapes andlighting of signs should be com-patible with the architecture of thebuilding, the business it identifiesand the character of the surround-ing area.

1. Lettering should be simple, legi-ble and well proportioned for clearcommunication.

2. Sign shapes should be simpleand straightforward to communi-cate well. Signs as symbols areencouraged because they are easi-ly read and add to the vitality of astorefront.

3. The light levels of a sign shouldnot overpower other signs on the

street or the facades ofnearby buildings.

4. A revocable permitmust be obtained bythe business owner forall signs incorporatedinto canopies, awningsor signs that projectover the public right-of-way.

5. Sign materials shouldbe durable and easy to maintain.

S i g n P l a c e m e n t

1. Signs on commercial buildingsshould fit within existing featuresof the building’s facade.

2. Sign location should not detractfrom or hide significant architectur-al details of the building.

3. The number of signs should belimited to avoid clutter. Too many

signs detract from thedistrict’s appearance andeven reduce business.

4. Wall and windowsigns should be placedonly near or within thefirst story window areaof a building.

5. If signs identifying abusiness district or his-toric district are includ-ed, they should belocated near intersec-tion entry points.

6. Consider designingnew buildings with

built-in sign bands to integrate signswith the architecture.

B. Regulatory Signs

Generally, standard regulatory andparking signs are installed by thecity. These can be coordinatedwith new streetscape design by

contacting the Transportation Divisionof Public Works. Proposed signs adja-cent to parks and parkways should bereviewed by the Department of Parksand Recreation.

Regulatory signs are often addedafter a streetscape is completed.The signs should not be placedwithout coordination with theproperty owners and projectdesigners.

X. PARKING

Parking in the right-of-way iscommon in Denver residen-tial neighborhoods. It should

occur in the street, along the faceof a consistent curb line. Treelawns should not be removed forparking in any residential neigh-borhood. The consistent, repetitiveplacement of street trees, and thecontinuous line of curb, tree lawnand detached sidewalk are moreimportant than the provision of afew additional parking spaces.

Integrating parking into the com-mercial areas is an importantaspect of streetscape design. TheDenver Zoning Code addresses thespecific requirements for parkingfor each zone district and use.

A. Parking Structures

Parking structures should bedesigned so that they are compati-ble with buildings in the area.

G u i d e l i n e s

1. The design of parking structuresshould be architecturally integratedwith the design and structure of thebuildings they serve. Treat the facadeof the parking structure to match thefacade of adjacent buildings.

2. Make the horizontal and verticalelements of the parking structurefacade similar to those of adjacentstructures. Also make the spacingand proportions of openings in thefacade similar to those of windowson adjacent buildings.

3. Use materials and textures on thefacade of a parking structure similarto those on adjacent buildings.

4. Provide clear signage to directthe driver to the parking structure.

5. If possible, locate retail or ser-vice uses along street frontage,with parking provided below-grade or as surface parking behindbuilding.

B. Parking Lots

Parking lot location and designshould minimize disruption of thecontinuity of retail frontage alongthe sidewalk. Walls, fences andlandscaping should be used todefine pedestrian space as sepa-rate from parking space.

G u i d e l i n e s

1. Where parking is located on asite with a building, locate the park-ing at the rear if possible. This willminimize gaps in the continuity ofbuilding faces along the sidewalk.

2. Parking lots should not beplaced at the sidewalk edgebecause it breaks the continuity ofretail on the street, particularly if aparking lot is placed on a cornerlot. Corner lots are better utilized ifbuildings are located on them, withparking behind or to one side.

3. If access to parking interruptsthe continuity of ground floor retailbetween multi-story buildings on ablock face, continue the upperfloors over the access drive to cre-ate continuity of facades.

4. The number of curb cuts shouldbe minimized to reduce conflictsbetween pedestrians and automo-biles and to increase the opportu-nities for landscaping the plantingstrip between the sidewalk andcurb. Where possible, adjacentowners should share curb cuts.

On-street parking can be accomodatedwithin most commercial districts withoutinterrupting the continuous line of the

curb, street trees, and walkway. Inaddition, the parking lane provides

another layer of separation between thepedestrian and moving traffic.

Locate retail at the street level of parkingstructures for visual interest along the

pedestrian walkway.

Walls and landscaping can be used todefine the separation between pedestrian

and parking space and improve theappearance of parking lots from the street.

C. LANDSCAPING

Landscaping improves theappearance of parking lots.In addition to differentiating

pedestrian space and auto space, itcomplements the surroundingproperties and improves environ-mental conditions. All applicationsfor landscape plans are reviewedby the Department of ZoningAdministration. See “Rules andRegulations for the Landscaping ofParking Areas” (Section 6) for thelandscape review procedure.

Berms used as a means to screenparking lots are seldom effectivedue to limitations of space. Slopedberms create numerous othermaintenance and resource prob-lems, especially when coveredwith turf. Screening can be moreeffectively accomplished through awise choice of plant material,fences, railings and low walls.

P l a n t M a t e r i a l s

1. All plants should be suited tothe Denver climate and suitable forconditions of the parking area.

2. Street trees should be includedin the tree lawn in front of all newparking lots. Trees should be even-ly spaced to provide a unifiedappearance. Refer to street trees inthis manual.

3. Planting areas must be coveredby turf, groundcovers or lowgrowing shrubs that are at least 6inches tall or higher where screen-ing cars is desired.

4. No artificial trees, shrubs, turf orplants may be used as landscapefor any parking area.

5. Groundcovers in planting areasmay include brick pavers or inter-locking pavers. Materials should beconsistent with adopted neighbor-hood plans and streetscape design.

6. Plain concrete, patterned(stamped) concrete and asphaltpaving are not acceptable ground-covers in required landscape areas.

S c r e e n i n g

1. If a parking lot or parking struc-ture is next to a sidewalk or isclearly visible from the publicright-of-way, a five (5) foot widelandscape buffer or a fence and atwo (2) foot wide buffer combina-tion is recommended.

2. The design of visual screensand landscaping along the parkinglot edge should be dense enoughto screen adjacent residences andpublic rights-of-way from headlightglare and the movement of trafficgenerated by vehicles using theparking area.

3. Fences, planter boxes and lowwalls can help screen the views ofcars as well as soften the appear-ance of the street.

4. Planter boxes and walls must bemade of brick, masonry, texturedor aggregate concrete. Chain linkor wire mesh may be used only incombination with plant material ofsufficient density to create ascreen. The fence should be eitherblack or green to blend with theplant materials.

5. Solid fences, hedges or wallsalong lot lines abutting the publicright-of-way may not exceed threefeet in height to allow visibilityinto the lot for security.

L i g h t i n g

1. Parking areas must have prop-erly designed lighting. A qualifiedlighting designer or the propertyowner must certify that the pro-posed lighting will produce theminimum footcandle levelsrequired by the Zoning Adminis-tration. See Rules and Regulationsfor the Landscaping of Parking

Areas (Section 5) for requirements.

2. Light fixtures should be of thecut-off (down cast) type, equippedwith house side guards andmounted in heights and locationsto minimize off-site glare. Fixturesmust be approved by the ZoningAdministration.

3. The owner is responsible tomaintain light fixtures and lightlevels to illuminate the parkingareas from dusk until midnight orone (1) hour after the end of busi-ness hours, whichever is the laterof the two.

W a l k w a y s

1. Private or public walkwaysshould have a minimum width of 5feet, exclusive of vehicle overhangwhich is typically 2 feet, 6 inches.

I r r i g a t i o n

1. Landscaped areas must have aproperly designed irrigation systemproviding full coverage on all plantmaterial areas. Impulse sprinklers,pop-up and surface spray sprin-klers or other means appropriatefor the areas to be irrigated maybe installed as determined by theZoning Administration.

2. According to the Guidelines forXeriscape Implementation, meth-ods for harvesting runoff water foruse on site are encouraged toreduce the need for potable waterfor irrigation and to reduce bur-dens upon storm drainage systems.

M a i n t e n a n c e

The property owners, their succes-sors, heirs, and assigns are respon-sible for the proper maintenanceof the landscaped area and park-ing lot subject to a landscape planapproved by the Zoning Adminis-tration.

XI. MAINTENANCEAND IRRIGATION

The property owner, mainte-nance district or businessimprovement district is

responsible for the proper mainte-nance of landscape areas in thepublic right-of-way fronting theirproperty. Maintenance includesmowing, weeding, cleaning, snowshovelling, raking, re-seeding andotherwise repairing all the land-scape and paving materials in theright-of-way including sidewalksand street trees. The only excep-tion to this occurs in the case ofdesignated parkways, where theParks and Recreation Departmentperforms landscape maintenanceof the medians. Median mainte-nance by the Parks and RecreationDepartment is not a given whennew medians are established. Eachcase must be handled individually,either by ordinance or by negotiat-ed agreement to establish howfunding for maintenance will beprovided. Contact the Departmentof Parks and Recreation for moreinformation.

Residential property owners whoparticipate in a tree planting pro-gram are required to sign aDepartment of Parks and Recre-ation Maintenance Agreement forany street trees planted in the pub-lic right-of-way. Property ownersare responsible for the watering ofthe trees and tree lawn in front oftheir property and the areas

between their property and thestreet. This area may be wateredmanually, however the inclusion of a properly designed and maintainedautomatic irrigation system canreduce maintenance, reduce waterconsumption and insure the healthof lawns, trees and plantings. Auto-matic irrigation systems are thereforehighly recommended for all plant-ings in the public right-of-way.

Dry wells are recommended forareas in which property ownersare willing to be responsible forhand watering in residential andsmall commercial areas only. Thiswater-conserving irrigation tech-nique involves watering the treemanually with a hose the firstthree or four years until the tree isestablished enough to survive onits own. Winter waterings are highlyrecommended for young trees dur-ing dry winters. Refer to Appendix A.

Landscaping must be maintainedcontinuously. This includes neces-sary watering, weeding, pruning,pest control and replacement ofdead or diseased plants. Replace-ment plants should be the sametype as used in the approved plan.Replacement time should not exceed one (1) year.

Listed below is a general overviewof maintenance and irrigationissues. Please refer to the follow-ing documents for more specificinformation (see Bibliography):

1. Denver Landscape Design andMaintenance Guidelines for WaterConservation.

2. Appendices B, C and D.

3. Irrigation Manual and StandardSpecifications (for projects main-tained by the Department of Parksand Recreation).

The following guidelines should beconsidered for the general upkeepand maintenance of public right-of-way improvements:

A. Trees, Shrubs and Sod

Proper maintenance can prolongthe life and beauty of landscaping.Basic care should include:

1. Monitor irrigation to avoid over-watering or under-watering.

2. Maintain tree spaces and landscapedareas including watering, cleaning,weeding, mulching, mowing, fertilizingand aerating when necessary.

3. Remove grates, paving materialsor any other material installed in thetree space when maintenance ontree or tree roots is necessary, andproperly reinstall when finished.

4. Replace grates or paving materi-als when damaged or destroyed.

B. Irrigation System

Commercial streetscapes should beirrigated with a properly designedirrigation system to cover all plantmaterial in the public right-of-way.If only a few trees exist on theproperty, dry wells (hand water-ing) may be utilized but only withthe approval of the City Foresterand with a written maintenanceagreement between the owner andthe city.

I r r i g a t i o n D e s i g n

Irrigation systems should bedesigned to permit turfgrass to beirrigated separately from all otherplanting areas. Turf irrigationzones should be further separatedby slope, aspect and turf typewater needs. Automatic irrigationcontrollers should have repeatcycle capability to permit moisture

to penetrate into the soil ratherthan run-off.

1. Irrigation schedules should beset when pedestrians are not likelyto be present.

2. Rainfall or soil moisture sensors,check valves, pressure reducersand flow sensor valves are alldesirable to reduce water waste.

3. Sprinkler heads in the samezone should have the same precip-itation rates. Pop-up heads in turfshould have at least a 4 inch riserheight.

4. Controllers should have thecapability to irrigate shrubs, flow-ers and trees separately from turf,and have time capability to permiteffective use of low volume sys-tems over longer cycles.

5. Perennial and ground coverareas may be irrigated with fixedriser or shrub pop-ups.

6. Pop-up risers should be fittedwith low pressure and low volumespray heads. Shrubs and trees maybe irrigated by drip or low volumespray heads.

7. Normal spray patterns shouldbe confined to mass vegetatedareas or root zones of plants.

8. Spraying of walks, decks,patios, driveways, buildings andfences should be avoided. If spray-ing of walks and bikeways cannotbe avoided, the controller shouldbe timed to spray at night toreduce conflicts with users.

Irrigation Maintenance

Irrigation is critical to the survivaland growth of plant materials. It isimportant, therefore, that irrigationsystems are cared for properly. Nec-essary start-ups, shut downs, period-ic checks, adjustments and replace-ments of parts must be performed.

1. Check system completely atspring start-up. Repair and adjustheads.

2. Monitor and adjust systemmonthly throughout the season.

3. Properly shut down and winter-ize the system at the end of theseason.

C. Lighting

It is critical that lighting is main-tained and that continuous electri-cal service is provided. The follow-ing procedures should be imple-mented:

1. Maintain lighting controldevices including timers, photo-cells, etc.

2. Replace damaged or missinglight poles or parts within 30 daysof damage.

3. Replace burned out bulbs orlamps within 10 days of burn out.

4. Perform general maintenancework including regular cleaningand painting when required.

D. Furnishings

Street furnishings must be main-tained to remain attractive andfunctional amenities. Painting,cleaning and repairing will helpensure a more desirable andenduring environment.

E. Sidewalks

Cracked, broken or missing side-walk paving is hazardous to publicsafety. Recommendations for side-walk upkeep are as follows:

1. Maintain concrete joints andreplace sealant when necessary.

2. Remove snow when necessary.

3. Remove trash on a regular basis.

51

Frequent mowing is an important aspect ofturf maintenance.

XII. APPROVALPROCESS

A. Streetscape Implementation Process

The following is a step-by-stepguide to completing streetscapeprojects, depending upon thesource of funding (public or pri-vate):

P r o j e c t s C o n s t r u c t e d u s i n g P u b l i c F u n d s

1. The Planning and CommunityDevelopment Office informsneighborhood associations throughpublications regarding the avail-ability of funding for streetscapeimprovements.

2. Property owners or neighbor-hood associations requesting astreetscape project submit anapplication to the Planning andCommunity Development Office. Itis reviewed by staff.

3. For Community DevelopmentAgency projects the property own-ers or the neighborhood associa-tion present their project to theMayor’s Advisory Council, which,recommends projects to receivefunding.

4. The city advertises a Request forProposal for architects orlandscape architects to design theselected projects. Funded projectsare awarded to designers chosenthrough a selection process.

5. The designer, under the direc-tion of The Planning and Commu-nity Development Office andDepartment of Public Works,works with the property owners orneighborhood association to pre-pare the project design.

6. All property owners are respon-sible for maintaining right-of-wayimprovements adjacent to the

property. If appropriate, a mainte-nance district may be established.Prior to construction, commercialproperty owners are required topetition the Manager of PublicWorks to establish a maintenancedistrict. (See Maintenance Districtsection and Appendix F).

7. A revocable permit applicationis made to the Manager of PublicWorks. Prior to construction, arevocable permit is required if aproject includes physical intrusionsoccupying the public right-of-way.

8. The city requests bids from con-tractors through an advertisementin local publications. A bid open-ing is conducted and a contract isnegotiated.

9. The city issues a “Notice to Pro-ceed” to the contractor.

10. A city-appointed project coor-dinator monitors the constructionactivities through completion ofthe streetscape project.

11. Following construction, citystaff monitors warranty items andfollow-ups with the contractor tosee that all items are completedand accepted. A reproducible as-built drawing should be turnedover to the city and or ownerbefore acceptance. All materialsare required to have a two yearwarranty except plants, whichmust have a one year warranty.

P r o j e c t s C o n s t r u c t e d U s i n g P r i v a t e F u n d s

Steps for the implementation ofprivately funded projects are simi-lar to publicly funded projectsexcept that owners are responsiblefor the funding, employment andmonitoring of architectural andconstruction services. Appropriatecity permits and regulations applyto all projects. Maintenance muststill be addressed either by individ-ual property owners, a Mainte-

nance District, or a BusinessImprovement District.

B. Revocable Permits

A revocable permit is an importantpart of streetscape projectsbecause it serves as a license forthe property owner to occupy thepublic right-of-way.

Prior to construction of streetscapeprojects in which a structure orother related items will encroachonto the city right-of-way or inwhich permanent occupancy ofthe right-of-way will exist, proper-ty owners are required to obtain arevocable permit.

This permit serves to protect thepublic, the city and property own-ers from any bodily injury or prop-erty damage that might result fromstreetscape improvements.

The city reserves the right torevoke a permit at any time forreasons regarding public safety,the owners failure to renew a permit, or other reasons. (Refer toRight-of-way Engineer, Departmentof Public Works.)

There are two types of revocablepermit available. The proceduresand regulation regarding both areas follows:

Revocable Permit by Ordinance (Ordinance Revocable , Type A)

Revocable permits by ordinanceare required where buildingsencroach into or overhang thepublic right-of-way; such as pedes-trian crossovers, tunnels under thestreet, underground parking struc-tures; and any improvementswhich affect the movement ofautomobile, pedestrian, and bicy-cle traffic between the curb linesof a street, such as traffic diverters.

C I T Y a n d C O U N T Y o f D E N V E R S T R E E T S C A P E D E S I G N M A N U A L

Revocable permits by ordinancemust be obtained before construc-tion can begin. This applicationand approval process for securinga permit by ordinance include:

Submit a letter requesting the revo-cable permit, addressed to theManager of Public Works. Refer toAppendix D for a sample letter.This letter requires the followinginformation:

a. The intention of the permit.

b. A set of architectural plans isprepared by a registered profes-sional architect indicating locationof the improvements. Upon reviewof the application by various citydepartments including Engineeringand Transportation a recommen-dation may be made to City Coun-cil for approval. A $300.00 fee isrequired when recommendation ismade to City Council.

Because of the length of timeinvolved in obtaining a revocablepermit by ordinance, a temporarypermit is available. This temporarypermit allows work to begin untilthe ordinance permit is received. Atemporary permit is available onlywhen an ordinance permit is readyto go to council; it is not possibleto apply for a temporary and arevocable ordinance permit at thesame time. Application can not bemade until initial review is madeby the Engineering and Trans-portation Departments. The costfor a temporary permit is $50.00 inaddition to the $750.00 processingfee and the $300.00 ordinance fee.

Exception: for city-funded pro-jects, the processing and ordinancefees ($1,050.00) are paid by thecity using project funds.

All revocable permits by ordinancemust be renewed annually at whichtime a fee of $50.00 is required inaddition to current proof of insur-ance. This renewal fee must be

paid by property owners.

Note: revocable permits by ordi-nance transfer from one owner toanother when property is sold.

For additional information contactthe Right-of-Way Engineer, Engi-neering Division .

Revocable Permits by Letter(Letter Revocable, Type B)

Revocable letter permits arerequired for temporary or lessextensive physical objects, otherthan trees and turf, occupying thepublic right-of-way. This type ofrevocable permit generally appliesto commercial streetscape projectswhich include items such asplanters, benches, bollards, trashreceptacles, pedestrian lighting,signs, tables, seating, awnings,fountains, fences, walls, irrigationsystems, meter pedestals, etc.

Revocable letter permits must beobtained before construction canbegin. To obtain a revocable per-mit by letter:

Write a letter requesting the revo-cable permit, addressed to theManager of Public Works. This let-ter requires the following informa-tion:

1. The intention of the permit.

2. A set of architectural plansshowing location of improvementsand prepared by a registered archi-tect or engineer.

Upon approval, a first year non-refundable processing fee of$75.00 is required. Evidence of lia-bility insurance with the minimumlimits of coverage of $50,000/$100,000 for bodily injury and$5,000 for property damage cover-ing the location of public propertyfor which the streetscape improve-ments and revocable permit arerequested. The city must be named

as additional insured on the policywith a thirty (30) day notice ofcancellation.

Exception: for city funded pro-jects, the processing fee of $75.00is paid by the city using projectfunds.

A letter permit is issued for oneyear, after which, property ownersmust submit a renewal request,current proof of liability insuranceand an inspection fee of $25.00annually. This fee must be paid byproperty owners.

C. Maintenance Districts

The formation of a maintenancedistrict is required generally whenstreetscape projects are at leastone block in length (or two endblocks) and include improvementssuch as pedestrian lights, benches,trash receptacles, planters, irriga-tion lines and other elements.

Projects involving only the addi-tion of grass trees and paving donot require the establishment of amaintenance district. For suchimprovement projects, however,the city requires a signed letter ofagreement expressing the commit-ment of property owners to main-tain improvements in the right-of-way along their property. Allagreements regarding maintenancemust be made prior to the prepa-ration of final design and construc-tion documents.

Commercial property owners aregenerally required to participate ina maintenance district. Propertywhich cannot be assessed, i.e.,non-profits, foundations, state andfederal property, cannot berequired to participate in mainte-nance districts and the city does notpay maintenance costs for thesecategories of owners.

If a streetscape project involvescommercial properties in less thana one block (or two end blocks)area or otherwise does not meetthe criteria listed above, the estab-lishment of such a district may notbe required. The formation of amaintenance district will be con-sidered on a case-by-case basis.The district or individual propertyowners involved in the project willbe required to obtain a revocablepermit to insure proper mainte-nance of the right-of-way improve-ments other than paving, grass andtrees along their frontage.

Process for Establishing aMaintenance District

A maintenance district requires aBoard of five members; at leastthree members must be owners ofreal property within the district orrepresentatives of owners of suchproperty or officers of corporationsowning such property. One mem-ber of the Board must be the Man-ager of Public Works. The Boardof property owners and the Man-ager of Public Works will thendetermine the maintenance budgetbased upon the estimated totalannual costs of upkeep. Propertyowners will be assessed on anannual basis according to the lin-eal footage of frontage facing theproject for their proportion of thetotal maintenance budget.

The city will not construct anyextensive public improvementswithout the assurance that theproperty owners will participate ina maintenance district. Upon com-pletion of a cost/benefit analysis aseries of events must occur priorto the actual establishment of amaintenance district. The projectcoordinator together with the par-ticipating merchants will beresponsible for completing the fol-lowing procedure:

1. Petitioning:

A petition, accompanied by acost/benefit analysis or linealfootage proportion, identifying theproperties to be affected, will becirculated to property owners.When the property owners repre-senting more than 50 percent ormore of the assessed valuation ofreal property, exclusive ofimprovements have signed andfiled the petition, the Manager ofPublic Works will advertise thenotice of a proposed local mainte-nance district for remonstrances(protests or objections) to be heardnot less than twenty (20) days afterthe last publication of the notice.

(Note: The Manager of PublicWorks may, in his official capacity,initiate and propose the establish-ment of such a district withoutreceiving a petition.)

2. Property Owner Protests:

If remonstrances are filed by prop-erty owners representing 50 per-cent or more of the assessed valu-ation of real property within theproposed district, exclusive ofimprovements, the maintenancedistrict will not be establishedwhether the district was initiatedby petition or proposed by theManager of Public Works.

3. Creating an Ordinance for Submittal to Council:

If remonstrances filed are not suffi-cient to prevent the establishmentof the maintenance district, theManager of Public Works will usu-ally approve the creation of amaintenance district and will sub-mit an ordinance to City Councilauthorizing the establishment ofthe district. This ordinance will gothrough Council twice, usually onconsecutive Mondays.

4. Appointment and Initial Meeting of the Board:

The Board for the maintenancedistrict shall consist of five (5)members, including the Managerof Public Works and at least three(3) members who are propertyowners within the district. Theymust then meet to approve thefirst year’s annual budget.

5. Hearing for Assessment Protests:

Once the budget has beenapproved, the Manager of PublicWorks will publish a notice to theproperty owners specifying eachowner’s proposed assessment.Objections or complaints can befiled at any time within twenty(20) days and will be heard byCouncil, acting as a Board ofEqualization, before the ordinanceassessing the cost is passed.

6. Assessment Ordinance Submitted to Council:

After all objections have been con-sidered by Council, any modifica-tions of the proposed levy will besent to the Manager of PublicWorks, who will prepare an assess-ment ordinance and submit it onceagain to Council and upon com-pletion of the second reading, amaintenance district will be estab-lished.

For a copy of the actual ordinance,see Appendix F.

D. Business Improvement Districts

An alternative to the formation of amaintenance district is to form aBusiness Improvement District(BID). A BID may assess both realproperty owners (landowners) andpersonal property owners (retail-ers) to raise funds for mainte-nance, among other things. A BIDis a quasi-governmental body,empowered to perform routinemaintenance, centralized retailmarketing and management andeven land acquisition, and devel-opment .

State House Bill No. 1182 providesfor the creation, operation andfinancing of Business Improve-ment Districts. A BusinessImprovement District is createdwithin a municipality upon thepetition of owners of real and per-sonal property in the proposedservice area of the district. Thepetition is filed in the office of theClerk for that particular governingbody. A public hearing is held andan ordinance is prepared thatestablishes the District.

The district has the power to man-age, control and supervise all busi-ness affairs of the district includingacquisition, operation, financing,installation and construction of dis-trict improvements, as well as thefunding and operation of districtservices. District services includeplanning, promoting, marketing,managing, business recruitment,security, maintenance, as well asdesign and public events assis-tance. The district board has thepower to fix, increase or decreaserates, tolls or charges for any ser-vices and improvements. Theboard may enter into contracts andagreements, hire employees orretain agents, borrow money, incurindebtedness, sue and be sued,and refund as well as sell bonds.The board may appoint an adviso-ry board of property owners locat-

ed within boundaries of the districtto advise them on local concernsand issues.

For more information on the for-mation and operation of BusinessImprovement Districts, refer toBusiness Improvement DistrictsFormation Process, The Office ofPlanning and Community Develop-ment or to the Districts and Alter-nate Government Financing Mech-anisms, Division of Local Govern-ment, State of Colorado.

E. Individual CommercialMaintenance Agreements

There are commercial streetswhere the uses are highly diverseand where the goals of the proper-ty owners are very different.

Contiguous uses such as: a publicschool, a retail business, a non-profit institution, a library or a resi-dence may not share similar goalsrelated to a streetscape project. Itmay not be feasible for these typesof unrelated uses to obligate them-selves to a Maintenance District. Ifso, individual maintenance agree-ments must be signed by eachowner who participates in the pro-ject. In addition, revocable permitsare required where applicable.Refer to Appendix C.

WATERINGGUIDELINES FORNEWLY PLANTEDTREES

In order to assure that your newlyplanted trees are healthy and vig-orous you must water them regu-larly for the first two years or so.Many factors can vary the frequen-cy and amount of water that yourtree will require.

Factors to Consider:

1. Species of Tree

2. Soil composition and structure

3. Exposure to drying winds andsunlight

4. Irrigated or non-irrigated area

In general, newly planted treesshould be watered once a weekfrom April through October andapproximately once a monththrough the winter. Again, weatherconditions and soil will play alarge role in this cycle. For exam-ple, if it rains well enough to soakthe soil, then watering is not nec-essary that week. Check the soilby digging 2-3” down with yourfinger to see if the soil is moist ordry. If you press the soil betweenyour fingers and it sticks togetherwatering is not necessary. Further-more, if the soil is sandy the treewill need more frequent watering.

During the winter trees should bewatered once a month. If the soilremains unfrozen or if little mois-ture is present, trees will requiremore frequent watering, especiallyif they are evergreen. If the soil isfrozen or there is a snow cover, additional watering is not neces-sary. Another critical time to wateris in the spring when new leavesbegin to form. In the second sum-mer the trees should be wateredapproximately every 10-14 daysdepending upon the amount ofmoisture present.

In the third year, if there has beena lack of moisture, extreme heat ordrying winds, watering may benecessary. Additional water maybe required for trees in irrigatedareas where the water is turned offfor any extended period of time.

If you have any questions, pleasecall Maureen Van Norden at 964-2544. Thank you for your help inkeeping Denver green.
