NEWCOMB & GAUSS CO., P.;..ea,e 1963 I Report of the Planning Board To His Honor Francis X. Collins, Mayor of Salem, and The Honorable City Council: GENTLEMEN: On March 8, 1962, the City Council accepted and adopted, and on March 12th the Mayor approved the Provisions of. Chapter 41, Sections 81A to 81GG of the General Laws of the Commonwealth of Massachusetts relating to "Improved Method of Planning" and Subdivision Control." Under the provisions of the law the Mayor appointed and the City Council confirmed the appointment of the members of the Board then under appointment. At the direction of the Board, Blair Associates (later Blair and Stein Associates), who were engaged in preparing a Master Plan for Salem, drafted Rules and Regulations governing the sub-division of land which were adopted by the Planning Board on June 18, 1962, and were recorded, as required by law, with the Register of Deeds of Essex Coun- ty, the Recorder of the Land Court, Boston, and the City Clerk of Salem. As provided by the law, the Board has considered 29 ap- plications that the Board endorse plans "Approval under the Sub-division Law Not Required." The Board has so en- dorsed 19 plans, has returned 3 plans to the applicants for further information and subsequently endorsed the plans when re-submitted, has returned one plan for further in- formation and subsequently endorsed the plan when resub- mitted, subject to conditions, has given two applicants leave 2 REPORT OF THE PLANNING BOARD to withdraw and their own requests and has reserved de- cision on the plans they have re-submitted, with the appli- cants waiving the provisions of the law requiring a Plan- ning Board decision within 14 days, and has endorsed one plan subject to conditions. After meetings and conferences with a committee of the City Council, the Board presented an amending ordinance which the members considered important and necessary to clarify and implement the existing Zoning Ordinance. This amendment, which was submitted to a public hearing as required by law, made provisions as follows: The islands within the municipal boundaries of the City of Salem shall be classed individually and col- lectively as a Single Residence District, whether such islands are shown or designated on the Zoning Map or not. The establishment of certain lots sizes and front, rear and side yard space in historical, single residence and general residence districts; lot sizes being restricted to not less than 7,000 square feet in the less developed area of the City, roughly comprising portions of Loring Avenue and Highland Avenue and adjacent streets and land; and in the remainder or built-up part of the city to not less than 5,000 square feet; thus dividing the city into two lot-size zones. Restrictions on the erection or relocation of new structures in the Historical Districts, requiring appro- priate exterior appearance. Exclusion of dwellings from Industrial Districts. Additional authority in certain instances for the Board of Appeal. Requirement that plans accompanying petitions for ` !- U I�e�,� ✓L�S � w� 3 0 l b 7� �-e� LrJ Ar 2-3 1-7 REPORT OF THE PLANNING BOARD - 3 amendments to the Zoning Ordinance shall be prepared by a registered land surveyor. Change of a single residence district on Swampscott Road adjacent to an existing business district to an industrial district extending to an existing industrial district. The proposed amendment, accompanied by a plan, was adopted by the City Council and approved by the Mayor, as shown in the records of the City Council. During 1962, Blair and Stein Associates prepared several reports for the Planning Board in addition to the Subdivi- sion Regulations. The first report was the Planning Inven- tory study, which analyzed existing conditions and trends in Salem. The Consultants projected 1980 population fore- casts for the city of between 34,350 and 49,600, with 44,900 as their "best estimate." After several meetings, many interviews and discussions, Blair and Stein Associates presented the results of its spe- cial study of the Central Business Ditrict. This report in- dicated a preliminary plan for the improvement of the down- town, and emphasized the need for urban renewal. The Con- sultants had previously recommended the establishment of a Redevelopment Authority. Further study will be given to the Central Business District in connection with studies in 1963. Blair and Stein Associates also reviewed with the Plan- ning Board studies of the urban renewal potential of Salem in residential neighborhoods. Their report on this subject will be published in 1963. Work has been proceeding on the planning of historic dis- tricts, major thoroughfares and over-all land use. In 1963, the Consultants will report on these subjects and on studies of the waterfront, schools, recreation, utilities, and zoning. 4 REPORT OF THE PLANNING BOARD It is with deep regret that the Board records the death of Peter C. Malkowski, a member since 1949. The Mayor has appointed John B. Hooper to fill Mr. Malkowski's unexpired term. Respectfully submitted, LOUIS E. BAKER, Chairman JAMES J. MUSE, Clerk JOHN M.
