73. B DEStGN STANDARDS for Mater{als-Architecturai Metats Iit-&14. Retain and p�eserve architectural metals,matalllc features,surfaces,as well as their form,pattem,detai{,color and texture,thcough approprfate meEhods. � NI•B•15. Clean soft metals with ehemica{cleaning solutions using ihe least intrusive method. Test�rst to assure that they do not damage the metal ar its flnish. Do nat clean soft metal surfaces with harsh abraslve methods. I(I•B-1S. Repaint architectural metal surfaces,when needed,using paint t�at is appropriate for the use. (Staff can provide assistance as necessary.} III-B-17. Repair deteriorated or damaged architecturai sarfaces and features using Vaditional methods for reinforcing, spBcing,or patching. - {A-B•18. Repiace deteriorated or damaged architectura!meia!only if necessary.<Match the original design,rnaterial, dimension,and detaiL Replace onfy fhe deterforated portion or detail rather ihan the entire feature whenever possibie. Consic�r compatible substitute material anly if using the original material is technica{ty not feasibte. fll-&19. tieplace a missing architecturai metaf feature with a new feature based upon accurate documenta�an of the origtnal or a new design campa6ble with the scale,size,material,and calor of ihe building on the loca!l.andmark P�pe1�Y• B DESIGN STANDARDS for Matertals—Roofina III-&20. The original roof material shouid be p�eserved whenever possibfe. Ifl-&21. R�f trim(fas�la,soffit etc.)should be mafntained and preserved. Necessary repairs shali be made using the same materials and the same pattem as the orfginal detaiL � III-B-22. Roof material on new addifions shtwld be compafible wifh exisfing roofs in material,type,color,etc. C DESIGN STANDARDS for Size�nd Scat__e ' IIbC-1. Malntain fhe size and scale of aU contributing buildings,especially the main house. Obvfously constructing an �dition will increase the size of a twilding. 7F�e addiGon should not dwatf the older porBons of the building or be so dominant that fhe buiiding fakes on an entireiy different character. IfI-C-Z. The proposal for any new addition should Incorpotate one ar more of the three cammon design tools:a cannecling breeieway,an eievation setback,or a change of materials. Iil-C-3. Maintain the relationship between the contribuGng buildings. Contributing buildings described in the designation Researoh Report shou{d not become overshadowed by new buiidings,e�usting non-con�ibuting buildings,or enlarged cantributing buildings,which vuere originally small, C DES{GN STAIdDARDS for Pr000rtian and Rhvthrn Ill-C-A. 7he combination of projecting and recessed features such as porches,doors and windows creates a sense oi rhythm that should be maintained. IIl-C-5. New additions should mafntain ihe propo�tion and rhythm of the existing building. III•C•6. �ront porches should be preserved as autdoor spaces. Requests to enclose porches in screen may be approved; requests to campietely endose porches wlth solid walis win likely be denied. III-G7. Porch posts and decorative trim should be maintained and preserved. Porch suppo�ts should noi be replaced with metal or synthetic posts. Porch trim should aot be removed,hidden,or simplified under synthetic siding. IIl-C•8. I#the porch on a designated property has to be replaced,the original porch shauld be repraduced as closeEy as possible. If ihe removed porch is not original to t�e house,the applicant shalf undertake sufllcient research to determine an appropriake porch design based on the age of the house,fts styie and dehailing. New porches and related Uimwork should never attempt to predate the house or to be overly elaborate. C DESIGN STANDARDS for Windaws and poors III•G9. 7he HPC encaurages the use of storm windows to pmtect histaic windows from deterioration. Ilt-C-14. F�xisting windows and doors should be maintained and preserved, IIl-C-11. 4Uhen windows must be replaced,new units should be the same slze,type,design,and materiaf as the orlginal windows. III�C-12. Windows and doors should never be removed,or`covered over"withou#repiacement Windows or doors that are not used.can be endosed using a traditlonal method such as lauvered blinds to create a"false"door ar window without disrupdng the balance. I!I•C•13. The HPC discourages the use of replacement aluminum or vinyl windows on contribufing buiidings consUucted � with wood windows. IIi-C-14. When new windows are used far an additlon or detached new construcfion project,unifs shouid have panes wif� ind'nriduai wood muntins{Uue-divided flghfs}. Windows with"snap-in°muntin grids are inappropriate for historic buildings. The HPG will discourage their use unless no other cost-effecfive altemaGve is availabie. The HPC will consider new technologEcal advances on a case-by-case basis. 1 9/27/2010 Draft Orange Counfy Design Standards 65
