<br /> property in scale,material,design,a�d color.
<br /> II-H-3. Minlmize the quantity of new signage and locate signage so it does nat diminish lhe architectural ar histaric
<br /> character of the landmark building,structure or site.

<br /> IIi. Maintenance&Exterior Changes
<br /> A DESIGN STANDARDS for M�intenance and Exterior Changes
<br /> IIl-A-1. Ail buildings located wifhin desfgrtated landmark prope�ies shouki be maintain�properfy. (See Secfion B
<br /> Materia{s:Wood,Masonry,Architectural Metals,and Roofing for�nore informa�on about the appropriate techniques fa�
<br /> di�ferenl buiiding elements.)
<br /> III-A•2. Trees and vegeiation sa�rounding Local Landmark buildings should ba Uimmed and pruned as necessary to
<br /> prevent long-term damage to adjacent sUuctures,
<br /> B D�SIGN STANDARDS for Materials-�Wood �
<br /> III-B-1.Retain and preserve historlc wood fabric such as siding,trim and details,and wood features that ara significant in
<br /> deflning the overall historic character of a contributing buifding,siructure,or s(te.
<br /> III-B-2. Maintain and protect wood features and surfaces with approprlate methods,always using the genUest effecfive
<br /> mefhod. Regular maintenance should include termite inspection andlor beatment.
<br /> IIf-B-3. Repaly deterlorated or damaged wood feafures through traditional patching,consolidating(with epoxy},piecing,or
<br /> reinf�rcing by other accepted preservation meihods.
<br /> III-B,4. f2eplace deteriorated or damaged wood features,if necessary,to match ihe original in deslgn,materlal,
<br /> dimension,and detail. Replace only the deteriorated pcxtlon or detail of a feature rather than the entire feature whenever
<br /> possible. Conslder compatible subsUfute materiais only if using the original material is not technically feasible. It is not ,
<br /> appropriate to replace ar cover wooden features such as siding,trim,or window sash with oontemporary substiEute
<br /> materials such as vinyl,masonite,or afuminum. in most cases,the HPC will deny requests to do so. Covering original
<br /> fabric with subsGtute materfals can trap moisture within the wall surface and damage the inner layers of sfdfng—and
<br /> evenfualiy the wall framfng system.
<br /> III-B•5. Replace a missing wood feature with a new feature based upon accurate documentatlon of the orfginal or a new
<br /> design compaGble wfth the seale,size,materlal,and color of the Locai l.andmark building. It is not appropriate to
<br /> intraduce wood fealures or details to a Locat Landmark building in an effort to create a faise historic appearanoe.
<br /> IIt-B-6. Mos#wood buiidings should be protecEed wifh paint or clear wood preservative to protect the material from
<br /> exposure to weather. The NPC daes not regulate paint coEors,but recammends the use of quality paint producfs in
<br /> traditional colors.

<br /> III-B»7. Retain and preserve masonry#eaiures such as brick,stone,concrete,terracotta,arid st�cco thaE are signiftcant in
<br /> deflning!he overall historic character of a Local Landmark building struciure or site.
<br /> Ili•B•8. Maintain and protect masonry features and surfaces by appropriate methads. Test any propased cleaning or
<br /> pafnt-removing technique well in advance on an inconspicuoas sample area. It is not appropriate to use destruc#ive
<br /> cleaning techniques such as sandblasting,power vuashing,ar high-pressure water blasting on historic masanry surfaces.
<br /> Use chemica{cleaners only iF genqer methods like low-pressure washing are ine�ective.
<br /> ' I!i•B-9. It is not appropriate to paint or coat an unpainted masonry surface if it was not pafnted or coated historically.
<br /> Repaint previausly painted masonry surfaces in tradi[ional colors--appropriate to ihe hisforic character of t�e property.
<br /> III•B•10. Repair deferiorated ar damaged masonry su�faces and features through b�aditlonal methods fo�consolida�ng,
<br /> piecing-in,or patching. Repoint masonry mortar jaints if the mortar is cracked,dateriorated,or missing or if mois[ure
<br /> pene#rallon of the masonry surface is evident. Prior to repolnting,use hand tools to carefully remove loase and ,
<br /> deteriarated moriar. Replace mortar with new mortar to match ihe origina!in composiUon,strength,coior,and fexture.
<br /> Duplicate the width and profile af the original mortarjoints. If is not appropriate to subsiittute modem coatings such as
<br /> water repellents for repainting or repairing hlstoric masonry. Consider such coafings onlyif traditiona!repair techniques
<br /> , fail to eliminate moisture proBlems.
<br /> IIl-B-11. Replace deferlorafed ar damaged masanry features,If.necessary,to match the orfginal in design,material,
<br /> dimensfon,and detail. Repface anly the deteriorated portion or defail of a feafure rather than the entire feature whenever
<br /> possiMe. .Consider compatible substltute materials anly if using tha orlgfnal materials are not fechnically feasible.
<br /> IH-B-12. Repface a m[ssing masonry feature with a new feature based upon accurate documentatian ofi the original ar a
<br /> new design compatible with the scale,size,material,and color of the Loca{Landmark buildfng.
