PROPOSED ACTION The action proposed is the adoption of amendments to the Town Master Plan based on review and analysis of the Town' s business districts by a joint committee comprised of Town residents and residents of the Village of Larchmont. The proposed amendments do not change the basic policies which have guided the Town' s development for many years but, rather, suggest refinements of these policies and specific measures to implement them. The principal recommendations involve each of the five sub-areas studied and are as follows: 1. A separate land use category oriented towards service business should be established and designated along Fifth Avenue and the Boston Post Road adjacent to the City of New Ro- chelle. Multi-family residential uses should be considered as an option in these areas. 2. Development of mixed residential and commer- cial uses is proposed as an alternate for larger sites (at least 60,000 square feet) in the business areas in order to encourage assemblage of smaller parcels, offer new housing opportunities and more flexible development programs. 3 . The existing business category should be revised to exclude automotive uses and, therefore reinforce its characteristics as a retail center. Minimum lot widths along the Post Road should be imposed to prevent the creation of small parcels and additional curb-cuts. 4 . The parking requirement for retial uses is excessive and should be substantially reduced to prevent the creation of needless expanses of asphalt. 5. Various actions to improve the visual quality of the Town' s business areas are proposed. 1 Where the above policies can be implemented through the Town' s Zoning Ordinance, appropriate amendments have been drafted. B. SIGNIFICANT IMPACTS AND MITIGATION MEASURES Possible adverse impacts considered are those related to increased density of mixed use develop- ment, reduction in the parking requirement for commercial uses , and designation of the service business area. These impacts were found either not to be significant or to be mitigated by other proposed related actions or zoning requirements. C. ALTERNATIVES Alternatives considered were for no action or for more direct involvement by the Town in implementa- tion of certain recommendations. D. APPROVALS The only direct approval required for amendment of the Master Plan is by the Town of Mamaroneck Planning Board. Referral to the Coastal Zone Management Commission for an opinion as to con- sistency with the Local Waterfront Revitalization Program is also necessary. Zoning amendments to implement recommendations of the Plan must be approved by the Town Board following referral to the Town Planning Board, the Coastal Zone Manage- ment Commission and the Westchester County Plan- ning Board. 2 i\TolsNi- czasoaoxa 3I1s 30 1ST OISaI?Is3cz II II _ DESCRIPTION OF THE PROPOSED ACTION- A. CTIONA. SCOPE AND PURPOSE The Master Plans for the Town of Mamaroneck and the Village of Larchmont were first prepared in 1966. The Town undertook an update in 1976. Some 20 years after preparation of the original plans, both communities determined that a comprehensive update was necessary to provide guidance for future planning and zoning decisions. A Joint Planning Group, which included members of various boards and commissions involved in planning, zoning, parking and other related municipal functions, was appointed to oversee the Master Plan Update. The planning consulting firm of Shuster Associates, supported by traffic and parking consultants Allan Davis Associates, was retained to assist the Joint Planning Group in its task, which was completed in two phases. The Joint Planning Group determined that the business areas of the Town and Village warranted highest priority for study. The basic purpose of the plan is to establish policies and guidelines for land use, traffic control, parking and design in the Study Area, based on evaluation of existing conditions, projected trends, and community objectives. Implementation of the policies is proposed in the form of specific actions--physi- cal, legislative or administrative. The complete text of both phases of the Master Plan Update, together with supporting maps and exhibits, is available for review in the office of the Town Administrator. B. BASIC POLICIES The Master Plan Update proposes the following basic policies to guide future planning in the Town: 1 . Business uses should be confined within boundaries delineated on the existing zoning map of the Town. 2. The existing scale and character of the business areas should be preserved and adjacent residential neighborhoods should be protected from adverse impacts caused by increased business activities, traffic 3 operations, parking lot expansions or similar conditions. 3 . Land use policies and development regulations should contribute to the appropriate use of existing underdeveloped or non-conforming properties and encourage development oppor- tunities that may be identified. 4. Land use policies, and the development regulations to implement them, should reflect the specific characteristics of the varied sub-areas within the business district rather than treat all business areas alike. 5. Policies and priorities for land use and parking must be developed jointly since they are integrally related. C. DETAILED POLICIES AND PROPOSED IMPLEMENTATION The Master Plan Update recommends detailed poli- cies and implementation measures for each of the five planning units designated in the Town. These are summarized below. Exhibit A includes a draft of zoning amendments proposed to implement certain recommendations. 1. Fifth Avenue a. Policies ( 1) This is one of the few locations in Town which is appropriate for various service type uses which, although not especially attractive or compatible with other uses, provide useful supporting services to local residents and businesses. These include automotive uses, storage, equipment rental, etc. ( 2) Service uses should be given preference over retail uses in this area, since it is the only such area in the Town. b. Implementation Establish a new Service Business (SB) District in the Zoning Ordinance, and amend the Zoning Map accordingly, which 4 permits service uses by right while requiring other commercial uses to obtain a special permit. Site planning standards for landscaping and screening should protect adjacent residential areas. 2. Madison Avenue/Myrtle Boulevard a. Policies ( 1) The business designation east of Madison Avenue is appropriate given the established uses and the few parcels remaining which have further development potential. ( 2) An excellent development oppor- tunity exists west of Madison Avenue, in the underutilized block adjacent to the public works yard. It is suitable for high density residential, office or commercial use (or combination of such uses) , has excellent access and visibility and there are no adjacent uses to be directly impacted by develop- ment. The primary consideration is that adequate parking and support- ing facilities be provided. Land use controls to permit such a range of uses--either singly or in combination--are preferable to the current designation, which allows only business uses, or an exclusive residential district such as applies in adjacent areas. As- semblage of smaller parcels in the block, to create larger, more efficient development units is to be encouraged. b. Implementation Amend the zoning regulations to es- tablish a new zoning district which permits a combination of residential, office and/or commercial uses in the B District, up to a height of 60 feet, and an F.A.R. of 1. 0 on sites of at least 60 , 000 square feet, subject to the issuance of a special permit by the 5 Planning Board. The special permit will require site plan review and adherence to design, use and functional criteria upon which the Planning Board will base its decision. 3. Myrtle Boulevard/Railroad Station a. Policy No changes in land use are appropriate. b. Implementation None related to land use. 4. Boston Post Road (Village of Mamaroneck to East Creek) a. Policy This area should be maintained as the location of large, self contained retail or office complexes. Further subdi- vision of parcels should be prevented and creation of additional curb cuts discouraged. Mixed use development on large parcels is also appropriate and consistent with this policy. b. Implementation (1) Amend the zoning regulations to establish a minimum frontage for business use and to refine the list of permitted uses to exclude automotive uses. ( 2) Encourage mixed (residential and commercial) use, subject to a special use permit, on large sites as an alternative to further strip commercial development. 5 . Boston Post Road (Lorenzen Street to New Rochelle) a. Policy Development of business uses on small parcels unsuited for such use should be 6 discouraged and opportunities for multi- family residential use, as an alterna- tive, should be provided instead. Incentives should be developed to encourage assemblage of small lots for appropriate business or intensive residential use. b. Implementation Redesignate all or part of this area as the SB Service Business District, and permit multi-family residential develop- ment subject to a special permit. 6. Design Guidelines and Plans A set of guidelines to serve the as basis for both public and private actions is proposed. In addition specific design criteria are recommended for use in specific situations, particularly in the review of proposed private development. Finally, a detailed design improvement plan for the Boston Post Road recommends numerous specific design solutions for particular visual problems and provides cost estimates to achieve the total plan. D. APPROVALS 1. Master Plan The Planning Board is given authority under §272-a of the Town Law to prepare and change a master plan for the Town. In accord with the Local Consistency Law enacted by the Town Board on June, 30, 1986, prior to approval of certain actions by Town boards or agencies, such action must be referred to the joint Coastal Zone Management Commission (CZMC) for its opinion as to whether the action is consistent with the adopted Local Waterfront Revitalization Program. The CZMC did informally review the proposed Master Plan Update and issue a report ( see Exhibit B) . The EIS will also be referred to the CZMC for their considera- tion. 2. Zoning Amendments Zoning Amendments recommended in the Master Plan Update must be enacted by the Town Board following the required public hearing. Such amendments must 7 be referred to the Town Planning Board, as set forth in §89-80B, for its opinion as to whether "the amendment would be in harmony with the Comprehensive Plan of land use for the Town" . The amendments must also be referred to the CZMC under the Local Consistency Law. Furthermore, under §239-m of Article 12-B of the General municipal Law, those amendments which affect property within 500 feet of municipal boundaries and specified state or county proper- ties must be referred to the Westchester County Planning Board. All of the proposed zoning amendments are within the specified limits. 8 - '''9' ��.,Ir 9q9. r/O. ✓ - v t \/ �V t..—""----.. ---17/..././ 11 / r ,. _W p4., ✓1.pO " ? .e PH6 EN Ce f\4I..(\SY�/l//7� % W N FPO O Fq P �•P G'90 Oey St -� RD• / '¢��` i S BEECH— t \".",,---/• q ME _ ._._ 7 `G� • > •��// k SC' RD.

UPDATE SHUSTER ASSOCIATES RD 1,Box 259 Stone Ridge,New York 12484 VILLAGE TOWN OF OF ALLAN DAVIS ASSOCIATES, INC., LARCHMONT MAMARONECK Traffic Engineering•Parking Studies III ENV-IRONMENTAT_ SETTING III - ENVIRONMENTAL SETTING A. OVERVIEW' The Town of Mamaroneck, which includes the Village of Larchmont, occupies an attractive but environ- mentally vulnerable six-square-mile residential area along the Long Island Sound shore of West- chester County--a highly indented and beautiful coastline totaling some nine miles. Proximity to New York and the beauty and recreational values of the area have attracted a high-income business and professional population of some 20,000. The area supports a prosperous economy based on residential real estate and including many retail and service establishments. Although most of the coastline is in private hands, there is wide access to the shore through private clubs and through public access to shoreline parks and conservation areas. Additional values include ecologically significant fish and wildlife habitats (primarily salt and freshwater wetlands) and sites of historical importance and scenic beauty. _ Of the approximately 6 square miles in this bi- municipal area one square mile--including about eight out of nine miles of highly indented coast- line--lies within the incorporated Village of Larchmont. The remainder consists of the unin- corporated area of the Town, which borders the Village on all its inland sides and also includes parts of two ecologically important pieces of shoreline and major parts of the watercourses that drain the area. Geography and patterns of development link the two municipalities in many ways. The Town-Village borders on both east and west run through eco- logically and hydrologically important stream beds and tidal inlets. Several of the two municipali- ties functions, notably sanitation and conserva- tion, are performed jointly. Town and Village residents share the same school district, post office, telephone exchange, and public library; many attend the same houses of worship and belong to the same local voluntary organizations. Thus, 'This section has been adapted from the Local Waterfront Revitalization Program adopted by the Town Board on June 30 , 1986. 9 the entire area shares an interest in the health of the same coastal zone. 1. Physical Geography Geologically, the area is part of the Man- hattan Prong, the southernmost portion of the New England upland geological province. The underlying rock structure makes for great topographical variety and scenic beauty, with hills and streams running down to a sound shore made up of numerous small bays, inlets and promontories. This advantage, however, is partly offset by environmental drawbacks. In many places the underlying rock is near the surface, limiting the capacity of the ground to absorb water and thus contributing to problems of flooding and siltation. These are serious problems for our community, most of which is drained by the Pine Brook, Sheldrake, and East Creek-Gut Creek water- sheds flowing through such rocky heights for much of their length. 2. Economic Geography This is likewise a mixed blessing. A loca- tion in a great metropolitan region--with a railroad and two interstate highways crossing the community, four large airports nearby (one major one being just across the Sound) , and substantial small industry and commercial water traffic along the nearby Sound shore-- brings important economic benefits; indeed, it is the basic source of employment for residents. But this location also brings environmental drawbacks: pollution of water, air and soil by aircraft, vehicular and industrial wastes; noise pollution; and the flooding and other evils that result from residential overbuilding. 3 . Economy The dominant business in the Town is residen- tial real estate. There is no manufacturing, and commercial enterprises in the area exist mainly to serve local or nearby residents. The area' s residential value lies partly in its ready access to New York City--as well as 10 to a widening array of suburban business, commercial and cultural centers--by both road and rail, but also in its physical beauty and the amenities and recreational advantages of its coastal location. Personal incomes cover a wide range, but the average level in the community is high. The resulting high residential real estate values, and the ancillary professional business (mainly retail) establishments, provide tax support for a high-quality public school system and efficient municipal services. 4. Population Growth The residential development of the Village and the Town has proceeded steadily since the late 19th century. Development of Larchmont Village took place primarily before World War II, while that of the unincor- porated area continued thereafter--in both cases with subdivision of large properties into single-family homes and construction of numerous apartment houses near the major east-west thoroughfares. The population of the area grew from 14,500 in 1940 to about 20,000 in 1970. Off the latter number, about 7,000 lived in the Village. These figures remained approximately unchanged through 1980. This stabilization underlines a fact of major importance for local planning, namely, that property in the area is already almost fully developed except for the exist- ing parks, golf courses, and conservation areas. 5 . The Natural Environment Environmental constraints are serious and increasing. As in other highly developed areas, these problems result primarily from decades of residential and commercial devel- opment without much thought being given to environmental impact. In many cases, inade- quate provision was made for sanitary sewage disposal and storm water drainage, and for maintaining a prudent balance between the built environment and the remaining open space. Developers, while striving to produce "flood- proof" structures in areas known to be flood- 11 prone, gave little if any thought to the flooding that their alteration of the land- scape could inflict on neighbors downstream; nor were such effects sufficiently considered by municipal planners. These conditions were aggravated by taxpayers' natural wish to broaden the tax base by more intensive zoning and exploitation of remaining open land. The price is now being paid in flooding, erosion, siltation, and pollution of ground, water and air, causing or threatening serious damage to property, to public amenities, and to local ecosystems, including fish and wildlife habitats. B. MASTER PLAN UPDATE STUDY AREAS 1. Fifth Avenue a. Existing Land Use This area encompasses both sides of Fifth Avenue between Madison -Avenue and the New Rochelle line plus the west side of Valley Place. It is an area of varied, sometimes conflicting, land uses and poor building and site maintenance conditions. The biggest single property in this area is the Thruway Authority headquarters. There are also several automotive uses, a nursery, some service/light industrial uses and some residences on and near Lester Place. The area has distinct boundaries in the Town consisting of the Thruway on the south, Madison Avenue on the east, and topographic change to the north; it is, however, a continu- ation of a similar area in New Rochelle to the east. Based on the relatively poor condition and low intensity of many of the uses in this area, it has more "soft" areas-- those with the greatest potential for change--than any other portion of the study area. 12 b. Traffic Conditions The principal thoroughfare serving this area is Fifth Avenue which carries just over 6,000 vehicles per day. This is well below the capacity of a two-lane street and moderate development or redevelopment of this area at inten- sities similar to those which presently exist can readily be accommodated. The principal traffic concern should be the proper location and spacing of driveways and the provision of adequate sight distance. c. Parking Field observations showed that there was little demand for on-street parking, the only municipal parking available in the area. Care should be taken that, when any changes in the use or density of this area occur, adequate off-street parking is provided through the zoning process. The present parking require- ment in the zoning regulations is quite high and should be reviewed on a case- by-case basis against the actual uses permitted within the area. It should be possible to reduce the present uniform parking requirement and encourage development necessary to upgrade the area while not creating a demand for parking beyond that which can be pro- vided, on-site, by each private use. d. Current Development Policies This entire area is zoned B (Business) , although it contains few of the prin- cipal uses permitted in that district. Neither the 1966 Master Plan nor the 1976 Update address this area in detail, although both designate it for continued business use. The bulk and area regulations for business uses in the Zoning Ordinance seem to encourage business development with urban characteristics, since no minimum lot area, width, or front, side 13 or rear yards are required and a floor area ration (F.A.R) of .5 is permitted. However, the parking requirement for retail or service uses (one space for each 100 square feet of floor area) is quite high and will result in very low density, spread out development if followed. e. Development Issues The basic issue in this area is whether it should continue to be designated for business use, under the same type of regulations as apply to the other business areas in the Town and Village, or should it be rezoned to more closely reflect its present use as a service area. Relationship of this area to the residential area to the north and the new apartments on the Garfield site across Madison Avenue must also be considered. 2. Madison Avenue/Myrtle Boulevard a. Existing Land Use Included in this area are a mixture of retail, office, industrial, service and residential uses bounded by the Thruway on two sides and intensive apartment development on the other two. The unit is bisected by the right angle streets of Madison Avenue and Myrtle Boulevard. Also included are 78 public off-street parking spaces and a substantial number of private parking spaces. The largest site in this area is two acres of Town and Village owned land, formerly housing the incinerator and water pumping plant, now used for the Town public works yards and recycling center. The remainder of this block contains a mixture of "soft" parcels-- including several small residences, a vacant supermarket and a vacant in- dustrial building--occupying an ad- ditional 2 . 5 acres . 14 The most substantial uses in this area are located on the north side of Myrtle Boulevard--an office building and several 4-6 story residential structures with first floor commercial uses. b. Traffic Considerations The principal thoroughfare serving this area is the combination of Myrtle Boulevard and Madison Avenue. Madison Avenue is intersected by the Thruway ramps which carry fewer than 3 ,000 vehicles per day, a relatively low flow for a highway access, probably due to the location of the toll station in close proximity. The intersection of Myrtle Boulevard and North Chatsworth Avenue is one of the more highly utilized intersections within the overall Study Area. Recom- mendations for improvements to this intersection, which operates in conjunc- tion with the intersection of Murray Avenue and Myrtle Boulevard just east, were made in a federally funded TOPICS study. Those improvements provide for a further separation of the two intersec- tions to provide increased storage space for vehicles waiting to make maneuvers between North Chatsworth Avenue and Murray Avenue. A small increase in the capacity of the intersection resulted from the project. The level of service of the North Chats- worth Avenue/Myrtle Boulevard intersec- tion was estimated for morning and evening peak hours and for the Saturday midday peak hour, based on traffic counts made in November 1985. The intersection was found to operate at a satisfactory level of service during all three peak hours. The level of service would remain the same with a 25 to 30 percent increase in traffic. Thus a significant amount of new development within the study area can be accom- modated without causing noticeable traffic congestion at this location. 15 c. Parking Considerations A parking study that included all on- street parking generated by development located within this area found that there was active parking on-street and in the Town lot fronting Myrtle Boule- vard on both weekdays and Saturday but that, with the exception of parking on the southerly Thruway ramp extension located just north of Jefferson Street, at least 15 percent of the available curb and off-street parking space was always unoccupied. The level of demand for municipal park- ing both on-street and in the Town lot indicates that present land uses within this area do not provide adequate parking to satisfy their own needs. It is important that future development within this area provides adequate parking to satisfy its own needs so as not to further exacerbate the pressures on the municipal spaces. d. Current Development Policies Most of this area is zoned for business use under the only business designation in the Town' s Zoning Ordinance. The Town/Village recycling center property at the end of Maxwell Avenue is zoned LI , Light Industry, the only area so designated in the entire Town. The 1966 Master Plan did not propose any change in the use of this area; however, the 1976 Update suggested possible indus- trial use of the block between Maxwell Avenue and Byron Place, adjacent to the recycling center. e. Development Issues The primary land use issue in this planning unit is the underutilization of the block bounded by Madison Avenue, Maxwell Avenue and the Thruway. This block is highly visible, has good access by car and train and would be appropri- ate for a variety of uses. However, its 16 efficient use is precluded by the number and small size of the separately owned parcels within it. The use of the Town/Village land could also have a significant bearing on development here if it were to become available. How- ever, the lack of alternate sites for these functions indicates that it will likely remain in public ownership and use. 3 . Station Park Area a. Existing Land Use The largest single use is the attrac- tive, well maintained Station Park. Most of the remaining area is devoted to the Town' s commuter parking lot. One building housing an automotive use and cleaners is the only other use in the area. The entire area serves as an effective buffer between the intensive development adjacent to the railroad and Chatsworth Avenue and the neighborhood of single family homes to the north and east. b. Traffic Considerations The principal thoroughfare serving this area is Myrtle Boulevard. Traffic on Myrtle Boulevard is relatively light, fewer than 500 vehicles per hour during peak hours. Present development patterns are practi- cally curb cut free and potential devel- opment is so restricted as to impose little concern from either a traffic safety or traffic capacity viewpoint. c. Parking Considerations The two predominant uses are the Town park and commuter parking. The parking is meter or permit controlled with permits available only to Town and Village residents. Approximately fifty percent of the spaces are controlled by 12-hour meters available on a first-come first served basis . 17 The principal parking issue is whether to increase the supply of commuter parking spaces. The parking surveys and analysis demonstrated that parking needs can be met by reallocation of existing spaces without enlarging the existing lot. d. Current Development Policies Both existing Master Plan and Zoning Ordinance reflect the existing use of this area and do not suggest any modifi- cations. Since virtually the entire area is Town-owned, the Town has ul- timate control over its use. e. Development Issues The only issue of consequence in this area is the use and operation of the Town' s commuter parking lot. While this site could, theoretically, be put to other use, it would require that the need for 300 commuter parking spaces be satisfied elsewhere or found to be unnecessary--both unlikely. 4 . Boston Post Road (Village of Mamaroneck to Village of Larchmont) a. Existing Land Use This area encompasses the northeast end of Boston Post Road in the Town of Mamaroneck, between the Villages of Larchmont and Mamaroneck, and exhibits the low density characteristics of post- war "highway strip" development, with large general retail stores and restau- rants predominating. Most buildings are fairly new, one story in height and have ample off-street parking. Distinct changes between commercial and residential land uses form the bounda- ries between Post Road development and adjacent areas on either side, while the northeast and southwest boundaries coincide with the boundaries of the two villages, into which similar patterns of 18 land use continue. This area also contains two shopping plazas, two banks, two four story apartment houses, a single family residence on Weaver Street, two car dealers, an office building and the only motel on the Boston Post Road in the study corridor. Most properties are generally well main- tained, with the more extensive land- scaping provided for the more recently constructed buildings. In the area a- round the Larchmont Motel, landscaping and sidewalks are in poor condition, and several incompatible uses exist. In addition, frequent building code viola- tions and arrests occurring at the motel pose a potential blighting influence on the surrounding area. Some of the larger parking lots have wide curb cuts that virtually eliminate the sidewalks and pose potential safety hazards for pedestrians. The least intensively developed parcel, adjacent to the International House of Pancakes, has recently been developed. Other properties capable of accommodating more intensive uses are the VFW site and the Larchmont Motel. b. Current Development Policies Almost all of this area is zoned B (Business) . In spite of minimal lot size and setback requirements, develop- ment is at a low density reflecting off- street parking requirements for offices, restaurants and retail establishments. The 1966 Master Plan and the 1976 Update call for continuation of the existing type of uses in this area. A portion of this area, containing the rear portion of the apartment house parcels, is zoned R-6 (Residential, 6, 000 square foot minimum lot size) . Both of the apartment houses are noncon- forming uses within both the B and R-6 Districts, which bisect their sites. The VFW post and the single family house on Weaver Street are nonconforming uses 19 within the B District. c. Development Issues There are two issues of concern in this area. ( 1) The existing Business District Zoning permits a broad range of uses including retail and service use, offices, commercial recreation and auto sales, plus additional uses subject to a special permit. The potential impact of some of these possible uses on adjacent residential areas, traffic flow and appearance may well be adverse, particularly in that some lots are vacant or have additional develop- ment capacity. ( 2) The appearance of this area suffers from a lack of a defined street- scape. There is little landscaping or street furniture along the right-of-way, unsightly utility lines, and excessive curb opening-- all of which detract from its visual character. 5. Boston Post Road (Village of Larchmont to New Rochelle) a. Existing Land Use This area consists of a mixture of residential and commercial uses develop- ed at varying densities. Several parcels have residences in the same structures as non-residential uses. Detached structures, housing from one to three families, are isolated by inter- vening commercial uses and vacant lots. In some instances lots in use for either residential or business uses have frontage on both Boston Post Road and streets parallel to it. Multi-family housing exists at two locations. At Dillon Road there is a five story apartment house with a ground level commercial use along the Post Road. Automotive retail and servicing are the 20 principal business uses. Several vacant lots exist along with an undeveloped street right-of-way (Van Guilder Street) . A number of these lots, which may be owned by adjacent property owners, along with the rear of the double frontage residential lots on Post Road, appear neglected or poorly maintained. This area is bounded on the southwest by a continuation of the automotive commer- cial land uses into the City of New Rochelle. Changes between commercial and residential land uses are distinct in some places and indistinct in others. The latter situation occurs in the lots with double frontage. As a result, residential and commercial uses can extend into districts where they are not permitted. b. Current Development Policies Most of the Post Road is within the Town' s B District. The rear of proper- ties on the northwest side of Post Road are in the R-7 . 5 District. The 1966 Master Plan for the Town briefly de- scribes the commercial uses in this area, whereas, the 1976 Update provides a more detailed examination of land uses and aesthetic characteristics. Con- tinuation of commercial land uses is supported in both documents. c. Development Issues Development issues in this area relate to its diversity in uses and property size. ( 1) The block on the south side of the Post Road, east of Dillon Road, is occupied by residential uses on narrow, step lots, although it is zoned for business use. Most of these individual lots are not suitable for business uses, but the general environment is not residen- tial in nature either. 21 ( 2) The mixture of auto related busi- ness uses on generally small lots creates special problems in terms of appearance, traffic flow and impacts on the surrounding neigh- borhood. 6. Design Issues on the Post Road The Post Road exhibits a diverse visual appearance, partly due to the different time periods during which development has taken place and partly due to inconsistent (or non- existent) attention to architectural and landscape design by both public agencies and private property owners. In general, the older areas in the Village have the most consistent quality, scale and level of design treatment. The other areas reflect the results of haphazard design treatment and "lot-by-lot" development. Because of the diversity of style, scale and function throughout the length of the Post Road, a single theme or character of design is inappropriate. However, it is important to develop design guidelines to address the various conditions which require attention and to establish appropriate procedures to ensure that the appearance of both public and private property is given serious con- sideration during the design and review process. Those elements which can and should be influenced by public design policy include signs (business and public) , street furniture and paving, parking areas and walkways, entrances to the community, and landscaping and screening. 22 s Tf1 'V a ISIOIJ1 IZIw QNINT S Ta V cTWI SNINT I EINC IS 11I •saznspaw buTMoTTo3 alp Aq paJpbT4Tu1 aq TTTM zo 4uEOT;TubTs ;ou zagpTa DIP anogp pa4EoTpuT s4opdWT oTjToads eqy •sTaaiEd TEzanas ;o ab'TqulassE ETA pa4Eazo eq 04 ATaxTT azp goTgM zo 4uauldo'anap Lions JO; pTza4Tzo pasod -oad alp 4aau1 TTTM goTgM seyTS 9TbuTs Me; E ATUO azp azag4 aouTs pa4Tu1TT azp asn paxTul ;o s40pdulT aATJETnumo TET4ua4od alp 'TEzauab uI •pa4Ezaua6 agspt abpMas pup abpsn za4pM paspaaouT pup uoT4Paaueb DT332zq paspa.zouT 'A4TTPnb ZpnsTA uT uoT4 -onpaz apnTouT A4Tsuap pup -414bTaq paspazouT aq4 u1ozg ;Tnsaz p'noo goTgm s;opduIT aqy 3T 04 S • go ?Iva UP u1oag pup saTzogs S 04 saTzo;s Z u1o1J 1OTz;STa g aq4 uT pa;4Tulzad AT4uasazd 4E114 puoAaq paspazouT aq p'noM OTTEz Eazp 1001 pup 411bT01.1 aq-4 '4uauldoTanap Bons zo; saAT.uaouT apTnozd oy •4uawdoTanap 8AT4E910 azoul zo; saAT-4 -uaouT apTnozd 0-4 pup sadA4 buTsnoq paTzpn zo; saT4Tun4zoddo a4owozd o4 '4uauldo'anap 4uaToT;;a azoul zo; savTs TTEu1s ;o abp'qulassp abpznooua O-4 zapzo uT 3OTz4STp SsauTsnq alp uT sa4Ts zablwT uo pa-4;Tutzad aq quauldo'aA -ap TETozaunuoo pup TET4uapTsaz ;o azn.xTu1 P gEgp sasodozd a4Epdn up'a za;sEw aqy ;opdull TEzauaD •T smNamao'IaAaa asn aaxiw ao syovawi 'y •u1ag4 a4EbTgTu1 04 'Azpssaoau ;T 'pasodozd saznspaw aq-4 puP s4opdwT 4uEOT3TubTs aTgTssod Mai aq . ;o uoTssnosTp P sT MoTaq 114zo; 4as •quP0T3Tu5TsuT zo aAT4Tsod z0114Ta a1P a4Epdn uETa za4spw aq , ;o uoT.dopp alp ;o s1opdwT 'p;uauluoiTAua aTgTssod aq4 ;o '.soul '.Tnsaz p Sy •spaiP ssauTsnq ;o aoupzpaddp pup ubTsap ago aoupqua 04 suoT4oP pup squaulpuaulp buTuoz TEzanas buTpnTouT 'saToTTod buTuuPTd oTspq s1uMoy alp anaTgop za4;aq 04 saznsuaw uoT.p.uawa'du1T uTp4zao s4sabbns a4Epdn aq-4 'zag4Eg •uoT4p'noITo oT3;Ez4 uT zo--TETozaunuoa puP 'pT4uapTsaz--sasn pup' oTspq ;0 uoT-4ngTa4sTp aq-4 uT pasodozd azp sabupgo 4uE0T;TubTs ON •uMoy aq4 uT saToTTod buTuuP'd pagsT'gp4sa buo' 30 s4uaulauT3az zagpzng squasazdaz a4Epdn uw'a za.sPw pasodozd aqy s��ns��rnt Hois�oi iiiw cr 2SIENT s scxligra oxr s trv- iii i wi - moi 2. Specific Impacts and Mitigation a. Visual Impact The only potential visual impact from the proposal for mixed use development would be due to the increase in per- mitted height. Such development will be subject to site plan review by the Planning Board and will be required to adhere to design guidelines included in the necessary criteria for issuance of a special use permit. Therefore, each development proposed under these provis- ions will be subject to careful scrutiny to ensure that visual impacts will not be significant. Furthermore, all of the potential sites for such mixed use development are in close proximity to existing uses of similar or greater height and are situated on major streets. Therefore, they will not be located in low density areas where they would be completely dissimilar to existing development patterns. b. Traffic Generation Total traffic generated by a mixed use development may be greater than that which would result from the purely commercial uses permitted under existing zoning. Since the proposed recommenda- tion will limit non-residential floor area to that currently permitted ( 40% x 1 . 2 FAR = . 48 FAR) traffic increases, if any , will be from residential uses. Based on data from the Institute of Transportation Engineers, it is es- timated that high rise apartments generate approximately . 35 trips per dwelling unit during the evening peak hour versus 9 trips per 1,000 square feet of floor area for a small shopping center. Assuming that an average apartment has 800 square feet, it would generate . 44 trips per 1,000 square feet, or about 5% of the rate for commercial space. The maximum addition- al residential floor area that could be created on a 60 , 000 square foot site is 24 43 , 200 ( 1 . 2-. 48 = .72 x 60,000 = 43 ,200) . Based on the trip generation rates set forth above, this floor area would generate 19 trips during the evening peak hour, an insignificant addition to the major streets serving potential sites. c. Increased Water and Sewer Usage If developed at the maximum density permitted in the existing R-TA District (one unit per 1, 500 square feet of lot area) a 60, 000 square foot site could accommodate 40 apartments, in addition to the commercial uses already allowed, under mixed used development. Assuming an average apartment size of two bed- rooms and water usage of 120 gallons per bedroom, approximately 10,000 gallons of additional water would be used per day. There are relatively few sites available for mixed use, none much larger than 60, 000 square feet. Although overbur- dening of the sewage treatment system is a major concern in the coastal area, the modest increase due to mixed use de- velopments will not significantly affect the status quo and be more than off-set by planned expansion and improvements to the system to increase capacity and reduce infiltration. Furthermore, site specific assessments of the environmen- tal impact of specific proposals will be required to carefully evaluate the effects of increased volumes on the sewage treatment system. B. REDUCTION OF PARKING REQUIRED FOR RETAIL USES The parking requirement for retail and services uses in the Mamaroneck Zoning Ordinance--one space for each 100 square feet of floor area, or 10 spaces per thousand square feet--is more than twice the ratio found necessary in several national studies of shopping center parking ( Institute of Transportation Engineers - 1987 and the Urban Land Institute - 1981 ) . Reduction of this ratio to one space for each 200 square feet will have a number of effects--all positive. The amount of asphalt required for retail development 25 will be reduced by half, thereby substantially decreasing storm water run-off. New retail space could be added to existing shopping centers which comply with the current requirement without adding new parking. Areas used for parking could be replaced by landscaping to enhance the visual environment. Thus, no mitigation measures are necessary. C. REVISED REGULATIONS FOR BUSINESS DISTRICTS Proposed changes in business district zoning-- modifications to the B District and creation of a new SB District--are intended to refine the function of existing areas devoted to business use rather than revise the intensity of use. The effects are, therefore, insignificant or positive. Prohibition of automotive sales and service uses in the B District will primarily effect the eastern portion of the Post Road by reinforcing its retail function and reducing automotive uses which have adverse effects on visual quality, generate pollution of storm water run-off and create land use conflicts with adjacent resi- dential areas. Increasing minimum lot width will prevent the creation of many small commercial uses with attendant traffic conflicting curb-cuts and inefficient parking arrangements. The proposed SB District will allow service type uses to congregate at locations where similar uses exist and land use conflicts can be reduced. Proposed site planning guidelines will provide the Planning Board with the tools to ensure that neighboring residential areas are protected. D. POST ROAD DESIGN PLAN IMPACTS The purpose of the recommended design concept for the Post Road is to enhance the visual environ- ment. The long term effects will be positive. However, the short term effects of construction activity may have minor adverse effects related to noise and dust generated and some minor incon- venience to traffic. These impacts will be mitigated by adhering to best management practices regarding erosion and dust control and scheduling construction so as not to impede traffic during peak hours. More detailed analysis of mitigation measures will take place during the environmental assessment for the specific construction program. 26 V UNAVOIDABLE ADVERSE ENVIRONMENTAL IMPACT S V _ UNAVOIDABLE ADVERSE ENVI12c MENTAi1 IMPACTS There are no significant, unavoidable adverse environ- mental impacts resulting from adoption of the proposed Master Plan Update and Zoning Amendments. 27 S21E10 S 21 .30 S Sr.iz w Iii MIMIC) 'Ig-%d11.UI2IS21III QIsI-NT Z IATSII _IVU 21211 I1L VI - IRREVERSIBLE AND IRRETRIEVABLE c c iw HUTMENT S OF RESOURCES There are no resources which are irreversibly or irretrievably commited by adoption of the proposed Master Plan Update and Zoning Amendments. 28 VII GROWTH INDUCING ASPECTS VII _ GROVITTH INDUCING ASPECTS Adoption of the proposed Master Plan Update and Zoning Amendments will only induce growth beyond that per- mitted under present zoning regulations in the case of mixed use development. Due to the limited number of available sites for such development, the effects of such growth, were it to actually take place, will not be significant. 29 VIII EFFECTS ON THE USE AND CONSERVATION OF ENERGY VIII - EFFECTS ON THE USE AND CON— ERVATION OF ENERGY The proposed Master Plan update and Zoning Amendments will have no significant effects on the use and conser- vation of energy. 3C) ii kii0 k q IX - ALTERNATIVES The substantially developed nature of the Town limits the number and extent of alternatives that could reasonably be considered in the master planning process or that would affect the environmental impacts. Thus, only two alternatives were considered, as follows: A. NO ACTION Throughout the planning process, the alternative of taking no action regarding each proposed recommendation in the Master Plan Update was studied--both individually and collectively. Those recommendations finally included in the proposed plan were determined to improve the Town' s land use policies by refining earlier, broader directions. To take no action would leave unresolved concerns which were the motivation for the Town to undertake the update in the first place. B. DIRECT ACTION BY THE TOWN With the exception of certain elements of the design plan, virtually all of the actions which would implement planning policies require private initiative. However, in certain instances, direct action by the Town may be appropriate to generate improvement in land use patterns where zoning regulations alone are not sufficient. In such cases, Article XV of New York State Law allows communities to address blight or potential blight by designating eligible areas and adopting a program to correct the conditions which have caused such problems. Upon adoption of an "urban renewal plan" for a designated area, the Town may use the powers granted under Article XV to acquire property or cause it to be rehabilitated, develop public improvements and dispose of property for use in accord with the adopted plan, as appropri- ate. The use of this technique could be con- sidered in the area of Valley Place, on the New Rochelle line, in the block between Madison Avenue and the public works yard, in the area around the Weaver Street/Post Road intersection which in- cludes the Larchmont Motel, and along the Post Road adjacent to the New Rochelle line. The use of this alternative will continue to be reviewed and, if found appropriate, may be pursued in specific situations. 31 EXHIB IT S January 17 , 1989 DRAFT LOCAL LAW NO. , 1989 TOWN OF MAMARONECK This Local Law is adopted pursuant to the Master Plan Update commissioned by the Town of Mamaroneck in order to implement the zoning changes recommended by the Master Plan Update for the purposes of revising uses and districts within the Town of Mamaroneck in order to more fully protect the orderly development of the Town. The Zoning Ordinance of the Town of Mamaroneck shall be amended as follows. 1. Section 89-4 of the Zoning Ordinance entitled "Districts Establishment" shall be amended by adding the following districts: Service Business (SB) District Mixed Use Business (MUB) District 2 . Add Section 89-28 . 1 Service Business District (SB) A. Principal Uses: (1) Indoor recreation or amusement establishments. (2) Business or professional offices.

The species materials to be used shall be reviewed to determine the effect of such screening at all times of the year. 4. Add Section 89. 28 . 2 , Mixed Use Business (MUB) District, as follows: A. Purpose The intent of this district is to create an opportunity for certain sites already in a Business District to be used for a mixture of commercial and/or residential use, to encourage flexibility in land use and site design, and to provide incentives for production of housing to meet the needs of a broad range of income groups. B. Procedure An MUB District shall be designated on the Zoning Map only upon application to, and approval by the Town Board of a zoning amendment in accord with the pro- cedures below as well as those set forth in Section 89- 80. ( 1 ) Location An MUB District may only be mapped in an area already designated in the Business (B) or Service Business (SB) District. ( 2) Submission In addition to any requirements for submission set forth in Section 89-80 or other applicable local laws, the application shall include the following: (a) A description of the proposed development plan including type and floor area of each use proposed, number of parking spaces, inter-relationship of uses and such other information as is necessary to provide a complete understanding of the proposal. (b) A preliminary site plan showing the location and height of all buildings, the design and layout of parking areas and driveways, a general landscaping plan and any other pertinent data. C. Principal Uses Same as in Business (B) District. D. Special Uses ( 1) Same as in Business (B) District. ( 2 ) Mixed use developments, including the following uses, separately or in combination, subject to the standards set forth below in Section E and approval of a site plan by the Planning Board: (a) Multi-family dwellings. (b) Business and professional offices. (c) Retail stores, personal service establishments and restaurants. E. Special Provisions for Mixed Use Development Uses proposed under the provisions of Section D. ( 2) above shall comply with the following standards: ( 1) Area and Bulk Requirements (a) Minimum site area shall be 60 , 000 square feet. (b) Maximum height shall be five floors, excluding covered parking and service areas, or sixty feet. (c) Maximum floor area ratio (F.A.R. ) shall be 1 . 2 . (d) Yards shall be as follows: Front: 25 feet (any yard fronting on a public street shall be considered a front yard. ) Side and rear: 25 feet or one-half the height of the nearest building wall, which- ever is less. ( 2 ) Residential Density For each type of dwelling unit the following minimum gross site area per dwelling unit shall be provided. Efficiency - 1, 000 square feet. One Bedroom - 1, 250 square feet. Two Bedrooms - 1, 500 square feet. Three Bedrooms - 2, 000 square feet. ( 3 ) Off Street Parking ( a) Off-street parking shall be provided on the site in the following ratio: Efficiency Units: 1 . 0 space per unit One Bedroom Units: 1 . 25 spaces per unit Two Bedroom Units : 1 . 5 spaces per unit Three Bedroom Units: 2 . 0 spaces per unit Retail/Office: 1 . 0 space for each 200 square feet of gross floor area. (b) Where it can be demonstrated that two different uses can share the same parking because of dif- ferent hours of operation, the total parking provided may be reduced to 125% of the spaces required by the use with the greater parking requirement. ( 4) Other Requirements (a) No residential uses shall be permitted on the ground floor or on any floor below a non-residen- tial use, except one apartment for maintenance personnel, and shall not share an entrance with non-residential uses. (b) Non-residential uses shall not occupy more than 40% of the gross floor area of all structures on the site. (c) Design Guidelines The following guidelines shall be considered by the Planning Board in its review of site plans and shall only be varied upon a finding that the objectives of this section are better served by an alternate plan. ( i) The total horizontal cross section of buildings over 30 feet in height should not exceed 15% of the total site area. (ii) Required front yards should be land- scaped and should not be paved except for necessary access drives.

V Town of Mamaroneck Village of Larchmont COASTAL ZONE MANAGEMENT COMMISSION TO: Town Council, Town of Mamaroneck Trustees, Village of Larchmont Town Planning Board Village Planning Commission FROM: Coastal Zone Management Commission (CZMC) RE: TOWN OF MAMARONECK-VILLAGE OF LARCHMONT MASTER PLAN, PHASES 1 & 2 DATE: September 14, 1988 The basic elements of the Master Plan, Phases 1 and 2, were presented to the CZMC at its regularly scheduled meeting of August 23, 1988 by Daniel Shuster, consultant to the Town and Village on this matter. To further consider its recommendations regarding the Master Plan, the CZMC held a special meeting September 1, 1988. Stated below are the principal recommendations of the CZMC arising from the meeting: 1. To protect the Pine Brook/Premium and the Hommocks marshland conservancies, and the drainage areas leading to them, the Commission recommends that: a) any construction activities within the drainage area of any of the waterways within the Town and the Village should utilize Westchester County Best Management Practices (LWRP Policy 14A, page 52, and Policy 33, pages 65 & 66) . b) For all automotive uses (garages, new and used car sales showrooms and storage lots, gasoline stations, and public or privately owned parking lots having a capacity of 20 or more automobiles) appropriately designed and sized oil separation units for stormwater runoff should be installed to protect both the East Creek and Pine Brook watersheds, designated Critical Environmental Areas (CEAs) and the shorefront. This recommendation, in addition to applying to all new construction, covers all existing such uses without adequate current oil-separation facilities, such capability to be installed retroactively. An integral part of this recommendation is the periodic inspection of such facilities by Town/Village personnel to assure compliance (LWRP Policies 7, page 4; 7A, page 45; 33, page 65; and 36, page 67) . EXHIBIT B Address Correspondence to CZM Commission, 740 West Boston Post Road, Mamaroneck, NY 10543 (Phone 914-381-6133) .i/ ,, -2- 2. For large undeveloped sites in both the Town and the Village, such as the nursery properties on the Boston Post Road, the Commission recommends that the municipality involved should consider increasing the minimum lot size in order to limit overdevelopment and, in the case of the nursery properties along the Boston Post Road, to minimize adverse effects on the adjacent CEAs. The LWRP, under Proposed Land and Water Uses and Projects, page 76, states the following: Post Road Locations The two nursery properties along the Post Road, both in the Village of Larchmont, are nonconforming uses in an area zoned R-7.5. Operation of a commercial nursery adjoining a high bank along Pine Brook has led to chronic problems of siltation and visual degradation. Should this property or its neighbor, or both of them, be developed for residential use, the environmental impact on the Pine Brook-Premium area, including the adjacent Premium River and Marsh, must be closely monitored and proper regulation applied. In order to promote environmentally sound use of these properties, Village authorities, in any future land use decisions concerning them, will apply such conditions and procedures, including site plan review requirements and environmental impact statements, as are appropriate in the light of policies in this Program concerning wildlife habitats, wetlands, flood and siltation/erosion control, and protection of scenic quality; and will bear in mind the status of those portions of the Pine Brook-Premium area, adjacent to and downstream fron these properties, that are designated as Critical Environmental Areas and/or significant or important wildlife habitats pursuant to this Program. The CZMC appreciates the opportunity to review the Master Plan, Phases 1 and 2, and remains ready to further elaborate on those phases and to advise on additional phases. cc: Stephen V.
