Although not as common as Vernacular Wood shuctures, these unpretenrious buildulg aie numeious enough to warrant a separate category. They are generally composed of brick, stone, or concrete block and am similar u1 massing to their wood counterparts As wifll Vernacular Wood structures, these builduigs are simple m detail and are designated accordutg to roof shape and floor plan mto four categories the Gabled "L", the Front Gable, the Hipped Box, and the Side Gable Italianate (1870-1910) Like many Victonan styles, the Itahanate emphasized verrical proparhons and richly decorahve detailmg. It was found on residenhal, commercial, and instrturional structures throughout Colorado from about 1870 up unhl the turn of the century and is either wood or masonry construchon The Itahanate style is characterized by a low pitched, hip roof, wicje overhangs, brlcketed cornice, a vanety of fenestrahon (usually very tall, 14 GENERAL DESIGN GUIDELINES Vernacular Wood Frame Vernacular Masonry Buckingham House Mapleton Avenue Itahanate Austin House Pine Street thm, doublc-hung, one-over-one wulnows), molded wmdow suiiounds, and occasionally a cupola oi balushaded balcony.

dates fiom the late 1880's through 1920 These structuies are basically one or two-story brick building with a flat roof and corUelled corruce The style is evident in a few single-family homes, but

Foursquare(1900-1930) One of the most commonly found styles m Colorado after 1900, the Poursquare is easily recogruzed by its square plan and overall simplicity The ma~onty of these homes werc built dunng the first thiee decades of flte 20~h century The typical Foursquare is a two-stoiy, hipped roof structure with central front dormer, mu~imal decorarion, broad overhanging eaves with brackets or modilhons, classical frieze with denhls, and a porch with hipped roof supported bu simple, Doric columns or squaie posts Occasionally, a Foursquare will feature a shaped gable or will be considerably larger with more elaborate oinamentatron, but, m each case, the basu square plan is predommant Classic Cottage (1910-1930) The Classic Cottage is basically a one-story version of the Foursquare It features an elongated lupped roof with central fiont dormer, a front porch with tluck poich posts or round, s~mpl~fied Doric columns supporfing the porch roof Popular between 1910 and 1930, the style was most commonly used in residenhal arctutecture, although occasionally it was used for schoolhouses, haui depots, or small uishtuhonal buildmgs Bu~lding materials were almosi always masonry,

REQUESTING DEPARTMENT: Jan Geden, CPRP, Director, Parks and Recreation Department Douglas R. Hawthorne, CPRP, Pazks Superintendent, Parks and Recreation Department FISCAL IMPACT: None BACKGROUND: Background mformation on th~s item can be found m the City Council packet of February 18, 2003 Dunng the second readmg, Council asked several questions. The Maich 4, 2003 agenda packet with answers to the questio~s is mcluded w~th this memo as Attachment A ANALYSIS: During the March 4, 2003 Council Meetmg, the Mayor and two other Council members pulled the Columbia Cemetery item off of the Consent calendar to ask additional questions about the proposed Ordmance. The followmg is additional mformation for Council to constder as to why certam restrictions are being proposed in this Ordinance Proiectiles The proposed restnctions on projectiles m the Columbia Cemetery were copied from the ban on pro~ectiles on the Downtown Mall These restrictions, which include snowballs and sticks as examples of the general category of pro~ectiles, have been m place on the Mall smce 1978. The prmcipal difference for the cemetery ~s the addrtion of "food items," which is m response to an incident at Columb~a Cemetery a few years ago The proposed ordinance also lists "paint balls" as pro~ectiles, because several markers have been defaced by th~s activuy. Final-CC_Apr15_2003-Second Readmg Columbia Cemetery Ordmance AGENDA ITCM #' lh'AGE # 1 Concerns were raised regardmg the restriction on snowballs and sticks in the proposed ordinance Durmg most Colorado snowstorms, the consistency of the snow is light and fluffy and would probably not cause significant damages to grave markers if one were struck with a ttuown snowball. However, snow of the heavy and wet consistency that fell durmg the March 11, 2003 snowfall would turn to ice ~f compacted as a snowball. Snow with this consistency could cause sigmficant damages to certain grave mazkers Afrer considermg lhis issue internally and takmg mto account the unusual nature of the March 11, 2003 snowfall, staff is recommendmg that throwmg snowballs and sticks be considered a legal activity in Columbia Cemetery, while still bannmg throwmg balls, rocks and other ob~ects. Reeulations in the Cemete Staff has approached the potential regulations on conduct m the Cemetery differently than those that apply [o our other park areas (such as no alcohoi, no dogs off leash, and no vandalism or lrttermg) Our reasons for these differences are twofold: 1 Cemeteries versus narks - Cemeteries aze not parks, and commonly there are restrictions on behavior in cemeteries bacause of theu nature and role in human soc~ety which would not apply m parks It is only by comc~dence that the Parks and Recreation Depaztment is mvolved m managing and maintainmg Columbia Cemetery As wrth the Downtown Mall mamtenance, Parks and Recreation was tasked with these responsibilrties because it has the equipment and expertise to mow grass and maintam landscapes Columbia Cemetery was grven to the City because the non-piofit private assoc~ation that owned it was not financ~ally capable of mamtainmg the property. Permanent Parks and Recreation Fund dollars have never been expended on Columbia Cemetery and it has never figured m the Departments mventoiy of pvks, plans for pazks, or assessments of the park land needs of the neighborhood m which ~t is located The fact that neighbors have trcated Columbia Cemetery as a neighborhood asset with diverse recreat~onal uses was considered by staff m makmg its recommendations on this ordinance to Counc~l Staff believes there are activrties of a passrve recreational nature that should be wclcomed in the Cemetery Reading in Columbia Cemetery, quiet reflection, bud watchmg, even picmcking are examples of activities that the Department would ]ike to see continued Stai'f briefly considered banning dogs entuely Yrom Columbia Cemetery, a regulation often found m cemeteries throughout the Country However, staff felt that such a ban would be unrealistic m Columbia Cemetery despite the fact that dog related activ~ties in the Cemetery are ob~ectionable to some and dog urine can cause damage to frag~le marble headstones. Since Columbia Cemetery is not a park, it presents hazards to nocturnal strollers which aie less prevalent in the developad urban parks Anyone walkmg off the mtertor cemetery road system runs the risk of tripping over low headstones, and there is some danger to the more fragile headstoues from people madvertently bumpmg into them Based on staffls research, a ttumber of municipal cemeteries m Colarado aze not open to the publ~c at night, mcluding those m Fort Collms, Greeley, Colorado Springs, and Loveland. The Columbia Cemetery Preservation Master Plan identifies the need to develop some mternal illumination of Cemetery grounds The Department sought State Historical Society Grant Funding for a project in 2002 to mstall a Final-CC_Apr15_2003-Second Readmg Columbia Cemetery Ordmance AGENDA ITEM #'~PAGE # 2 minimal levei of rught trme dlummation. The project for hghtmg m the Cemetery was not approved by the State Historical Society because of a concern that illumination is not in the histor~c character of Columb~a Cemetery Thus, fundmg for any type of illummahon will have to be borne entirely from the dedicated .25% sales tax fundmg for historic preservation. Due to l~mrted funding resources from the .25% sales tax fund, usmg matching grant fundmg for headstone stabilization and preservation is a higher priority at this txme Therefore, staff has no mtentions m the foreseeable future to illummate Columbia Cemetery In August 2001, vandals, under cover of darkness, toppled 33 headstones m Columb~a Cemetery This incident, and ot6er similar incidents of vandalism in the past, certamly tmpressed upon Lhe Department the des~rability of reducmg the risks of further acts of that sort The Oregon Cemeteries Association reports that Oregon's historic cemeteries face their greatest threat every year durmg the month of October. As Hallowsen nears vandals begin to prey on graveyards. The Oregon Historic Cemeteries Association (OHCA) reports that "the typical profile ~s a Caucasian male between the ages of 12 and 22. He generally is accompanied by one or more friends, is operating under the cover of darkness or in a secluded area, and frequently is using drugs or alcohol." Due to the contmued concerns about vandalism in Columbia Cemekery, especially consideimg the precarious condit~on of the histor~c asset and its location m an area where the vandal profile, as deternuned by the Oregon Historic Cemeteries Association, exists and due to conhnued concerns about safety for people walking in or through an unlighted Columbia Cemetery after dark, staff is contmuing to propose mghttime resCrichons m Columb~a Cemetery Staff felt that neighboring citizens would be more apt to ieport activrties in the Cemetery ~f they knew the Cemetery ~s closed to all after dark, rather than relymg on reportmg activities occurring after dark if the Cemetery were not closed ___~ 2. Protection of Cultural Resources - Columbia Cemetery not only has historic features but also has a very severe problem with the stability of headstones. Staff is planning on laying down approximately 300 headstones withm the next few months to prevent theu falhng over and potentially breakmg or m~urmg someone. In November 2002, our headstone restoration consultant, David Via, mformed the City of potential safety conceins with some of the headstones and activrties he was observmg. Mr. V~a, a nationally noted headstone restorat~on contractor, was concerned about the type of acUVities occurring m Columbia Cemetery and the stabllity of headstones based on his experiences working in othei cemeteries throughout the country Mr Via reported, "the number of dangerous monuments m total and those in proportion to the whole is likely the largest m any cemetery that I have visited." Additionally, Mr Via notified the Department that, "the subsidence of the soil over the graves seems to be greater than many other locations that I have visited. Many of the monuments have tilted towards the graves and have, or are ready to topple Many of the monuments have toppled multiple times and have not been pmperly repaired or reset This is understandable, as monument repau- is a specialized profession " When the Parks and Recreation Department received notification of thts issue by Mr. Via, staff contacted the City's Risk Manager and proceeded to mform the publ~c of the potential dangers Final-CC_Apr15_2003-Second Readmg Columb~a Cemetery Ordmance AGENDA ITEM #'V PAGE # 3 via signage in Columbia Cemetery, mventoried ail of the markers m the Cemetery, and identified and placed survey tape around the most unstable markers A press release on this subject was issued on March 26, 2003 which ~s mcluded as Attachment B. Smce that t~me, staff has heard from some members of Council, as well as c~tizens with concems about tlus proposal. The Department will be conductmg a public meetmg somet~me durmg late April to discuss, with mterested citizens, the purposes oF laying down the grave markers, as well as the process used to determine which markers will be lowered The Parks and Recreat~o~ Department has also made application to the State Historic Fund for a new grant to contmue with the restoraUon of approximately 90 markers. As restoration funds become available from state and ot6er sources, these will be re-erected m a more stable manner but it could take years to complete this work Staffls imtial approach regarding headstone rubbmgs was to regulate this actrvity so that proper materials and techniques could be used and precautions taken so the headstones would not be damaged, rubbing materials would not stain the stones, and adhesives would not remam on the surfaces of the slones. However, after reviewing the literature in the ficld and considering the stab~l~ty problems that exist at Columbia Cemetery and the durabihty issues regardmg sandstone, limestone, marble and other less durable stones or matenals, staff recommends that headstone rubbings not be allowed. The interestmg features of various headstones can easily be captured on film, or dtgital photography that allows image manipulation so that the appearance of a rubbing can be easily produced. The Department has recently developed a new web site for Columbia Cemetery which ~s accessibie from the Parks and Recreation Department's lmk on the City's home web page The general public can now access general mformation about the history of Columbia Cemetery, access bunal mformation and see digrtal photographs of the approximate 3,000 headstones The Department worked with the Carnegie Branch Library for Local History, Mary MeRoberts, and the Boulder Genealogical Society m providmg histonc mformation for the web srte STAFF RECOMMENDATION: The conduct of visitors m cemetenes, the extent that the cultural tesources m Columbia Cemetery should be protected from damage and m~ury by laws, and the mcremental value of measures_like night ume closures in decreasmg vandalism at the expense of other values are certamly cor[unumty value tssues. If Council believes that mght time visits should not be banned, it could either amend the proposed Saction 8-7-3 to use a time frame other than sunset and sunrise, or delete the section altogether Regarding grave rubbmgs, deletion of section 8-7-8 would leave that activrty legal, though ~f this is Council's determmation staff recommends retuinmg to Council at a later date with a sepaiate ordinance regulating grave rubbmgs Staff alrcady has provisions for grave rubbing regulations saved from previous drafts Staff recommends makmg the followmg change to Section 8-7-5: Strilce "snowballs" from the subsection (b), and add a subsection (c) to read~ "(c) Snowballs are not pro~ectiles withm the meaning of this section." If Council chooses to exclude sticks from pro~ectiles, staft's recommendation is to erther add the word "and sticks" after snowballs both to what should be Final-CC_Apr15_2003-Second Readmg Columbia Cemetery Ordmance AGENDA ITI:M #~UPAGE # 4 struck from subsechon (b) and mcluded m the new subsection (c), or strilce the words "snowballs" and "sticks" from subsecuon (b) and move the word "and appropriately." There is always tension between the theoretical value of many regulations and their practical effect. Staff believes that posting the Cemetery rules will have a beneficial effect in educating and infor~ung the public about this histor~c cultural resource.
