<br />Midrown Sp"clfic Plan <br /> <br />Building Envelopes <br /> <br />General <br /> <br />The pennitled building envelopes in !he CiviclProfesslOllal District are <br />defined by height and front yard se!back requiremenls established for <br />each block. Their primary purpose is to estabfish the relationship <br />between public and private pedestrian space and the building wall, <br />which fonns its edge. Setbacks define pedestrian space at the <br />ground level and show where higher buildings (greater than 35 feet) <br />can be sited. <br /> <br />Exhibit 1 0, CiviclProfessiooal Dislricl Height and Selbacks, provides <br />Ihe setback dimensions from property lines and other benchmarks <br />Ihroughoutlhe distric~ and height limits and setbacks (or buildings <br />higher than 35 feet. Reference information on Ihe exhibit shows <br />existing buildings thai are likely 10 remain, thereby indicating <br />relationships between existing buildings and potential new <br />development or realizalion. <br /> <br />Also shown for reference are major features of the comprehensive <br />plan, including major open spaces. planned parking facilities. <br />pedesman access ways and recommended ground ftocr arcades. <br /> <br />Building Heighf <br /> <br />Height is specified by number of stories and feet as measured from <br />:urb height. <br /> <br />Generally, the maximum heigh I for alllow,rise buildings is 35 feet. <br />Buildings above 35 feet in Ihe CivicJProfessional District include <br />existing office towers on Main street and Broadway and potential <br />office towers dustered at the interseclion of Main streel and Ninth <br />Street, where heights may be up 10 120 feet. <br /> <br />The towers are set back 15 reet from Ihe Main Street and Ninth <br />Street property lines or edge of the Ninlh Street private pedestrian <br />way. A maximum diagonal dimension is also specified to encourage <br />slender lowers. <br /> <br />An optional tower configuration is shown for a business hotel on the <br />Bu[lum's block, whereby two hotel lowers would be permitted with <br />appropriale spacing belween and a maximum 140 foot diagonal <br />dimensiOll. <br /> <br />Setbacks <br /> <br />Setbacks al ground level are eslablished 10 enhance pedestrian <br />space Ihroughout the district, creale compatible relationships <br />between existing and future building street walls and recognize <br />opportunities 10 creale new open space resources. such as plazas, <br />pedeslrian ways and landscaped areas. <br /> <br />;he major setback COIIditions are discussed below by street <br /> <br />30 <br /> <br />Main Street. A variely of conditions exist, bul mosl buiidings have <br />no setback. thereby resulting in a tight. urban sidewalk character <br />of minimal width. Major exceptions are the church plaza al <br />Tenth and Main and the existing tower belween Eighth and <br />Ninth, which is setback 12 feet and has a 13 foot wide ground <br />level arcade. <br /> <br />The potential fulure tower sites al Ninth and Main would <br />maintain !he 15 foot se!back condition and provide a 15 foot <br />wide ground level arcade in the selback. <br /> <br />The towers would be setback 15 feet rrom all property lines. <br />thus reftecting the siting of all existing lowers on Main street. <br /> <br />Open space and plaza amenities to be maintained and provided <br />include the existing church plaza at Tenlh Slreet, a wide <br />sidewalk area across the slIeet mirroring the wide sidewalk area <br />north of Tenth, a corner plaza at Ninth and Main to provide an <br />entry court for the potential tower, and a pedeslIian plaza in a <br />portion of the abandoned Seventh Street right-of.way. <br /> <br />Ninth Slreet Pedestrian Way, This planned private access way <br />is 40 feet wide and lined with 15 fool deep ground level arcades <br />along most of its lenglh. Ilterminales in a 70 fool wide plaza. <br />also lined with arcades, on the wesl side of Broadway, <br /> <br />Civic Center Drive, The eKisling building walls will create a <br />variegated landscaped area with varied and generous se!backs <br />along the street, providing an aesthetic foreground for Ihe <br />cluster of older buildings of character likely to remain, and <br />conlributing 10 Ihe parkway characler which exists along much <br />of Civic Center Drive. <br /> <br />Broadway. Twenty foot setbacks are established for alf new <br />developments. This will permit the landscaped character of <br />Broadway north of Washington to be continued to soulh or <br />Tenth Street. The exceptions are existing buildings that remain. <br />which have less the 20 foot selbacks. <br /> <br />Sycamore Street. Sycamore functions primarily as a local service <br />slreel and provides access to existing and planned parking. <br />Three variations 10 the standard condition of zero selback occur: <br />Ihe church plaza al Tenth Street and a wide (35 fool) selback <br />across Ihe street 10 exlend Ihe landscaped character: comer <br />setbacks and arcades al the Ninth Streel pedestrian way <br />intersection with Sycamore; and landscaped parkway areas at <br />Civic Cenler Drive. Vine pockets are encouraged along parking <br />structures and a 10 fool landscaped selback is required at <br />surface parking lols. <br /> <br />Church Plaza. An expanded landscaped open space is planned 10 <br />enhance the setting for the church. The south edge would be <br />defined by a ground level arcade. <br /> <br />Ordinance NS-2649 <br />I?~g" 17 of 72 <br />Midtown Specific Plan <br />
