    SchematicDesignRecommendationsThe following summarizes the site specific design recommendationsthat are incorporated into the facility plan as shown on the 1"=50f-0"scale schematic design drawings. Portions of the drawings have beenreproduced as plan details below to illustrate concepts.Jones Mill Road CrossingThis section describes the recommendationsfor crossing Jones Mill Road when the RockCreek Trestle is reopened to trail users andtrail use increases significantly.

    Once the Rock CreekTrestle is reopened, itwill be difficult to keep trail usersfrom crossingJones Mill Roaddirectly at the trail (see Figure18) . Appropriate sidewalk widths, cross-walks, clear sight lines, and timing of pedes-trian signals will needto beaddressed.Existing ConditiondlssuesCurrently, the existing GeorgetownBranchTrail users are directed to the existing cross-walks at the signalized intersectionof JonesMill Roadand Jones Bridge Road. There isa

    push buttonfor pedestrians. However, thetiming of the signal change is not frequentenoughto keeptrail users from jaywalking.

    When the RockCreekTrestle is reopened,there will bea large increase in the number oftrail users desiring to crossJones Mill Roaddirectly at the existing Georgetown BranchTrail right-of-way. However, southboundmotorists on Jones Bridge Roadturning rightonto Jones Mill Roadcannot see the trailintersection(Figure15).showing limitedThere isan existing sidewalk onthe south-boundside of Jones Mill Road leadinguptotheexisting crosswalks. However,there is nosidewalk or shoulder connecting the existingcrosswalkback to thetrail on the northboundside of Jones Mill Road(Figure 16). Currentlytrail users head north to the intersectionofJones Mill and Jones Bridgefor a shortdistance and cross at the signal to SusannaLane and into Rock Creek Park (see Figure

    17).

    OptionsConsideredTwo options were considered for addressingthe intersection ssuesat Jones Bridge Road:directingtrail users to the existing intersec-tion, or expandingthe intersectionto incorpo-rate the trail crossing. A pedestriancrossingor underpasswas also considered, butultimately rejecteddue to the uncertainty ofthe future Transitway design and thedesire ofthe trail users to eliminate unnecessarychanges in grade. A rampsystem withundesirable visual impacts and right-of-wayrequirements from adjoiningpropertyownerswould have beenrequired.Option 1: BarrierDirectingRail Users toExistingCrossingThis optiondirects trail users to the existingcrosswalk byconstructing physicalbarriers(42" high minimum)to deter them fromcrossing the street directly at the GeorgetownBranchTrail crossing of Jones Mill Road.This option would require that the existingconnecting sidewalk onthe west (south-bound)side of Jones MillRoad beutilizedand that a new connecting sidewalk beconstructed onthe east (northbound) side ofJones Mill Road(requiring the constructionofa timber retainingwall).The existing signalwould need to be modifiedto lengthenthe 'WK' hase of the signal.The existing intersection raffic volume data

    would needto beexamined to determine thefeasibility of modifying he pedestrianphaseofthe signal and its impact on level-of-service.Additional modifications to accommodate theincreased number of trail users at the existingcrosswalks include:Accessible curb ramps (2)Relocate northboundand southboundsignal poles to make room for trail userswaiting to crossPaintedcrosswalks with longitudinal linesfor addedvisibilityOption2: Redesign(Expand)the Intersec-tion to IncorporatethemilCrossingThe second option is to redesign(expand) theintersectionto include the trail entrance to theintersectionso that the trail users can crossJones Mill Roaddirectly.

    trail users without backing up traffic. Thetiming of the signal should be designed toaccommodate500 users per hour at peakweekend and summer evening use.In addition to the signalization changes,surface markings and signage would berequired according to the Manualof UniformTraffic Control Devices (MUTCD) guidelines.iese markings and signage include:"Pedestrian Crossing" warning signs (onall three approaches to the intersection)"Bike Route" marking signs (2)Painted crosswalk with longitudinal linesfor added visibility"Pedestrian Signal" regulatory signs (2) atthe trail crossingConcrete aprons at the trail crossingwhere it meets the roadway travel lane.vf an agreement with MCDPWT cannot beworked out regarding the signal, then barrierswill need to be constructed to direct trail usersto the existing crossing. Barriers will need tobe of sufficient size (42" high) to keep trailusers from crossing over the top and mustmeet County roadway design guidelines.Over time, pressure may increase for adedicated pedestrian phase (all red lights) atthis intersection. To accommodate thispotential change, the guardrail should bedesigned so that an opening could be createdfor the trail, leaving the rest of the guardrail inplace. The guardrail will then continue toprotect the approach sections to the trail,making it safer to access the trail from neigh-borhoods to the north and south.

    interim route will need to be used as aconstruction bypass route to keep the trailopen during the TransitwayITrail constructionperiod. Where the Rock Creek Trestlecrosses the existing Rock Creek Trail, over-head protection will be needed for trail usersbelow, if it is to be used as a constructionbypass.CommunityUnkagesThere is an existing on-road bike lane alongJones Mill Road south of the trail crossing.This bike lane should be connected to thefuture Capital Crescent Trail as a Shared-usesidewalk by reconstructing 8' wide sidewalkswith a 4' separation from the road edge andincorporating a box beam guardrail for furtherprotection. Currently, reflector poles mark theseparation.Both alternatives will require right-of-way andsidewalk improvements along the north boundsides to connect the trail with adjoiningneighborhoods to the notth and south of thetrail crossing. A timber retaining wall wouldneed to be constructed to support the side-walk on the northbound side of Jones MillRoad and an existing split rail fence wouldneed to be relocated.

    Relationship to Pmjwed TmnsitwayThe TransitwayrnailDraft EnvironmentalImpact Statement (DEIS) indicated the use ofdepressed grades to allow for a below gradeTransitway and trail crossing of Jones MillRoad.During construction of the Transitway, aconstruction bypass route will be needed westof Jones Mill Road (beyond the scope of thisstudy.)TheexistingSusannaLaneIRockCreekTrailThe Maryland-National Capital Park and PlanningCommissio

    Jones MillRoad - StewartAvenueThis section describes the recommendationsfor improvements to the existing GeorgetownBranch Trail that will be needed once theRock Creek T M l e s opened (beyond thosethat will be included with the Rock CreekTrestle reconstruction project).ExistingConditiondlssuesThe existing trestle (Figures 20 and21) willbe replaced with a prefabricated bridgestructure built on existing piers and footings.The project will be bid out in early 2001 as adesign build project. It is anticipated that thedesignlbuild project will include any surfaceand safety improvements needed to accom-modate an anticipated evel of peak use at500 userslhour.When the Trestle reopens, it will raise anumber of issues that will need to be ad-dressed immediately including the Jones MillRoad crossing discussed above:Drainage problems east of the bridge

    caused a washout of the trail.The surface will need to be improved toaccommodate the full range of users thatare anticipated. This may require atemporary asphalt surface that will requireless maintenance than a crushed stonesurface. The crushed stone surface onexisting portions of the Capital CrescentTrail do not receive adequate mainte-nance to ensure safety.An overlook and rest stop with seatingshould becreated as part of the perma-nent trail design to take advantage of theattractive views and provide opportunityfor interpretation of the Rock Creek Valleyand the history of the Georgetown BranchRailroad.A linkage is needed to connect the trail toRock Creek Park. The permanentTransitwayKrail alignment will be locatedon the south side of the proposed Transit-way, and therefore, the linkage will needto also beconstructed on the south sideto avoid potential Transitway and trailuser conflicts.

    The current interim trail connects to theGeorgetown Branch Trail at the intersectionofTerrace Drive and Grubb Road. This accesspoint should remain and the interim trail (anon-road bikeway) converted to a communitylinkage.

    BetweenGrubb Roadand StewartAvenue,thefollowing conditionsshould beaddressed:There are extensiveamounts of debrisand litteralongthe trail betweenLyttonsvillePlaceand StewartAve.There are manytow trucks and deliverytrucks crossing the trail using the existingright-of-way. There is not an adequatesight distance for the vehicles crossing thetrail to see oncoming trail users (bicy-clists). This should becorrected intheinterim by first placingstop signs for trailusers and second, providing"bicyclecrossing" warning signs for vehiculartrafftc onthe driveways. A permanentsolution should be incorporated nto theTransitwayKrail project design.Drainage improvementsshould be madein the washed out areas near the Countysalt domes (Figure 22).

    A concernwas raisedabout the aestheticandenvironmentalquality of the industrialarea betweenLyttonsville Road andStewartAve. Dueto the proximityof theTransitway, the aesthetic enhancementswill need to be designed andconstructedas part of theTransitwayrrrailproject.There is not enough room to make theseimprovementsnowwithout havingtoremove them later. There is notenoughinformation known about the final align-ment of the Transitway (1 or 2- track,etc.) to preparea design. However,aesthetic enhancements in this area arecritical to improvingthe overallquality ofthe trail experienceandthey should beincluded in the finalTransitwayKraildesign.

    Proposed lmpmvementsInterimimprovements includedwith theopening of the Rock Creek Trestle (byMCDPWT)The interimtrail will be openedwith onlyminor modification o the existing trail surfaceas neededto makethe trail safe. Debriswillneed to be removed, drainage problemsfixed,and the surface made usablefor a peakanticipateduseof over 500 userslhour.SurfaceOverall, it is recommended that the interimtrail for the CapitalCrescentTrail be con-structedutilizing a temporary2-inch asphaltsurfacealong with minor modificationsto theexisting ballast to support the trail, as dis-cussed in the General Design Recommenda-tions on page 9. Asphalt is recommendedover crushedstone. Asphalt will be easier tomaintainand safer to usethan the crushedstone surface, andwill be morecost effectiveover the temporary periodbetween theopening of theTrestleand the constructionofthe Transitway.This would provide a much safer and morefamily oriented temporary surface for trailusers. If theTransitway is not funded forconstruction, then the asphalt surface can berepairedand resealed. The crushed stonesurfacewould requireannual maintenanceandwould not be suitablefor all types ofusers, such as young children, roller bladers,strollers,etc. Norwould it be ideal for usersinwheelchairs.The County Councilwill have to approve theuseof the asphalt andstipulatethat it will bea temporary surface. This would have to beimplementedseparatelyfrom the Rock CreekTrestle DesignIBuildprojectdue to budget.However, the asphalt couldsimply be laidover the top of the preparedsurface thatresultedfrom the designtbuildproject.Stormwater management will also have to beincorporated nto the designof the asphaltoverlay. Drainageshould be consideredaspart of the Rock Creek Trestle designlbuildproject.

    CreekLinkageThe linkage to Rock Creek Park can beachievedby constructing a switchbackalongthe entire portionof the existingCounty right-of-way utilizing a 5%maximum slope switch-ing back at the east end of the right-of-wayand then descending down on a 5% slopepath to the park property. Most trees can bepreservedby utilizinga switchback to mini-mize cut and fill neededto accommodatethetrail linkage.raryT PI-

The nearest parkingwit Lyttonsvile

    Place isat Rock Creek Park and is used byjointagreementwith the Synagogue. The temp*rary trailhead should include a kiosk, paytelephone andwater fountain. These should

    be located so that they do not have tobemovedat a later date.Trail Crossingof IruthMalDrivewayThe trail should beon a raised"speed ablenwhere the industrialdriveway crosses thetrail. A speed table isa raised platform longerthan a vehicle designed to slow drivers downto an acceptablespeed (usually lessthan 15mph) Signs should beplacedto warn driversof the crossing and speed table.At the same time, stop signs should beinstalledfor trail users, includinga warningsign, stop bar, concreteapron, bollards, andcrosswalk striping with longitudinal markingsto increasevisibility.This dual approach clearly gives the vehiclesthe right-of-way at the intersection, but slowsthem down to a pointatwhich they can reactand drive defensivelythrough the intersection.Relationship toProposed Transhay/Tmii (PermanentAlignment)The Transitway alignment shown inthe DElSis proposedto runalong the same alignmentas the existing interimtrail. The permanentalignment of the trail is envisionedto beoff-center along the southernedge of the right-of-

    way on a lowerterrace. This necessitates heconstruction of retainingwalls to accommo-date both the Transitway and the permanentalignment of the trail within the available right-of-way. Therefore, a permanent trail cannotbeconstructed betweenJones MillRoadandStewart Ave. until the retainingwalls aredesigned as part of the Transitway/Traildesign phase.Const~ction ypassA bypasswill beneededduring the construetion phaseof the Transitway/Trail project tomaintaincontinuityalong the Capital CrescentTrail. It is recommended that the existinginterim route from Susanna Laneto the RockCreekTrail connecting through Rock CreekPark to FreymanandTerrace Drivescould beusedagain as a constructionbypass (pinkdashed line onthe Facility Plan, Figure 5).The Transitwayrrrail DElS indicatesthat theRock CreekTrailwhich crosses under theRock CreekTrestle would have to beclosedduring construction. Alternate approaches toconstruction management should beconsid-ered to keep the trail open as muchaspossible.From the Terrace Drive access, the Countyowned right-of-way iswide enough to con-struct a permanent section of the trail as a"constructionbypassn o connect with theWshington Suburban SanitationCommission(WSSC) property on LyttonsvilleRoad. A trailconnectioncould be incorporated nto existingproperty setbacks (either along the northorwest side of the property, connecting toLyttonsvilleRoadthrough the WSSC prop-erty).This then connectswith the Rosemary HillsRecreation Center providingaccess to LanierDriveand the TalbotAvenue Bridge. Tempo-rary "Sharethe Road" and"Bicycle Route"signs should be placed along the constructionbypass route as part of the Transitway design.

    CommunityLinkagesA permanent, off-road, shared-use sidewalk isproposed asa community linkageto connectthe CapitalCrescentTrailwith the GwendolynCoffield CommunityCenter. This linkagecould beconstructed prior to the Transitway1

    Facility Plan for the

    Trail project. A portion of this linkage could beused asa construction bypass for the Transit-way project. The linkage would utilize the eastside of LyttonsvillePlace and the north side ofLyttonsville Road. Itwould cross the street atmid-blockbetween the intersectionof Figum 28: ViewLyttonsvilleRoad/Lyttonsville Placeand looking east onMichiganAvenue.

    ing linkage, and to protect the existing streettrees.Accessible curb ramps, painted crosswalkswith longitudinal lines for greater visibility,along with hazard identification beacons wouldbe needed for the mid-block pedestriancrossing. Located along the low volumesection of Lyttonsville Road, this sectionprovides a safer place to cross to get to theRosemary Hills Recreation Center than at theintersection of Lyttonsville Road andLyttonsville Place (with its continuous rightturn allowed without stopping).The community linkage crosses two drive-ways, requiring the installation of new curbramps. No utility poles would have to berelocated to accommodate the communitylinkage.Coordination IssuesThe interim trail alignment should be re-viewed by the Mass Transit Administration(MTA) to ensure coordination with theTransitwayfirail project.The existing interim trail (Susanna Laneconnecting to Rock Creek Park to TerraceDrivelGrubb Road) will need to be used as aconstruction bypass for the Transitwayfirailproject.The Rock Creek Trestle designlbuild con-tract should include all of the measures
