�� C DESIGN 37ANDARDS for Roo#lines and Roof Details tll-C-15. The original roof pitcli and the ridge height should be retained. The canshvction of any new darmers or skylights should nof be visible ftom any publ(c road and shouid be on the leas#visible sectfons of the roof from within the property boundary. ill-C-18. AIt chimneys should be preserved and repaired using the same material,paftems,and methods as the origina! constnlction. New chimneys should not visually compete wifh arigina!chimneys. C DESIGN STANDARDS for Other Imaortant Yisual Features ill-G17. All characfer-deflning elements and exter'ar features should be presenred. tll-C-18. Elements that cannot be repalred should be repiaced in kind. tl1-C-19. Additions,and new construcGon,should never dominate e�sting build(ngs. De#ails(roofline,door,and window him)and ofher visually important molding on additfons and new freestanding bufldings should be visualiy compatibie with defaiis on existing buiidings. New trim should mainfain the proportions of the ariglnal U�im in a simplifed version;it should never overpower ihe ariginai#rim. Moreover,new ttim should never predate an exisfing structure anless it is part of a researched restoration or repraducfion project. D DESEGN STAIdpARD3 for Reversibilitv III-D�1. Large additions should be cons#ructed as stand-alone units placed abngside exisifng bulidings,not integrated into the structu�e. Additions shauld be consGvctad so that they can be removed fn the future should circumsfances change. ffl-D-2. Care should be used when locating new or moved buiidings to a Loca!Landmark property. New detached • construction and relocated older buildings should 6e able to be removed from the site without altering ihe overall character of the property. New or maved buitdings should nof diminish fhe historic integrity of the Local Landmark property by Eheir iacation on the site. � (See Standards ior Introducing Buildings to a Landmark Property.} E DESIGN STAMDARDS for Utitities and Enerav Retrofit • tll-E-1. Refain and preserve traditiona!or inherent energy-conserving features of the histaric 6uildings such as porches, screen doors,etc. q1-E-2. Install narraw profile exterf�r or interior storm windows so that they do not damage or obscure e�asGng sash and ' wlndow frames for energy efficiency. Choose stam windows fhaf are painted or flnished wifh a color compaGble wilh the exisfing sash color. if coverfng double-hung windoaus,select operable starm windows with dividers that align with existing sash division. !!1-E•3. Install fiull-light storm doors,constructed of wood or aluminum pa(nted or finished with a color that is compatible wlth the calor of tfie existing door for energy efficlency. Install storm doors so that the origlnal doors and frames are not obscured or damaged, Iq•E-4. InstaN mechanical systems with care so alteraffons to the contributing historic building are minimized and iEs character-defining elevations and features are nof compromised. ill-E-5. Locate new transformers,meters,pipes,and mechanical or communicaiion-related equipment as inconspicuous{y as possible,usually in rear yard locafions or along non-character-defining elevations. Screen mechanical or communica�on equipment with landscaping or opaque fendng. po not locate new mechan€caf or communication-related equipment(sateilite dishes,solar panels,etc.)on roois or elsvations visible from the road,or visible on the approach to the front door. Inspect and repair roof surfaces before installing solar panels. Consider lnstaHing solar panels on garage roofs with sou#h-facing exposares instead af the house roaf to limit the patent{ai for interior damage shoul�the roof leak. III-E-6. Locale portable air-condiiioning unifs,if needed,on rear or non-character-defining elevatians. 111•E-7. The use of underground wir(ng is encauraged where possible,but be sure to protect signiflcant site features, including archaeological resources and mature vegetation,from damage if underground utility and communicatlon lines are installed. F DESIGN S7'ANDARDS for Accessibilitv and Safetv Considerations IN•F•1. Determine if solutions fa ADA requirements are compatible with preserving fhe Local Landmark property's historic character and setting. fll•F•2. Seek input from Iocal disability groups and preservafion specialists in developing appropriate solutions to accessibiiity. Ilt-�-3. When possible lacafe accessibility and lffe safety changes such as ramps,elevator additions,and fire doors an fhe rear elevation or a non-character-defining efevation of the Local Landmark building. 11!•F•4. Design any new ar additlonal means of access or egress sa that the change is reversible and the original design of the his#oric entrance or porch is not compromised, 1 9/27/2010 Draft Orange County Design Standards 66
