INTRODUCTION As per the request of the Mayor and Board of Trustees, this office has undertaken a comprehensive analysis of the land use development pattern and zoning regulations applicable to the Hawthorne Avenue area. Specifically, the area under study is the same as that which is included in the interim development law, or moratorium area, for the Hawthorne Avenue area (see Figure 1). As you are aware, the Village has determined to undertake an analysis of the Hawthorne Avenue area based upon a belief that the area's development pattern is unique within the lower portion of the Village of Rye Brook, constitutes an attractive neighborhood that is worthy of preserving and has been historically developed in a pattern that is not consistent with the underlying zoning currently in place. Although the area is zoned either for single- family dwellings on 7,000 -square foot lots or two-family dwellings on 5,000 -square foot lots, the historical development pattern throughout much of this area has generally been one of large single-family homes being developed on lots of 15,000 to 20,000 square feet or more in size. In addition to analyzing the land use development characteristics and zoning applicable to this area, this office has also reviewed the articulated policies, goals and objectives of the Village relative to the preservation and development of areas such as the Hawthorne Avenue study area. The remainder of this report is devoted to providing the results of our analysis of this area, including but not limited to the Village's stated goals and objectives for development such as exists in this area, the development pattern which has shaped this stable and largely developed neighborhood, the inherent conflicts between the zoning standards applicable to this area and the development patterns existent there, the relative merits and disadvantages to rezoning this area to one or more other zoning districts, and our recommendations regarding actions the Village Board of Trustees may wish to undertake. Before proceeding with the study's full analysis, several items are worth noting. First, any changes to the regulatory structure affecting this area for the purpose of preserving the area's unique and attractive character can never be designed so as perfectly match the individual developments that have occurred on each and every one of these lots, most of which were developed during a different period in the history of land use regulation. That is to say, the development of the various lots within the study area often is not consistent with the standards of the applicable existing zoning (R-7 or R -2F), with the standards called for under any other existing zoning district within the Village or with the development pattern of any of the surrounding neighborhoods. Consequently, although the area is marked to a very substantial degree by large, stately homes on lots considerably oversized relative to both the underlying zoning standards and the development patterns of surrounding neighborhoods, building setbacks and lot width dimensions have not been developed in a manner wholly consistent with that which would be expected from a modern development created under the more careful scrutiny of today's regulatory administration or the zoning standards of the Village's larger lot zoning districts. II. ANALYSIS A. Policies. Goals and Objectives At the request of the Village of Rye Brook, this office completed a study in 1986 entitled Rye Brook Center Development Plan Update• Preliminary Report. Since that time, the report has served as a planning tool for the Village in the development and review of its land use policies and decisions. The first paragraph of this report reads as follows: 2 "The Village of Rye Brook administration has been faced with a variety of development proposals over the short period since its incorporation. The Village Board has recognized the importance of establishing and confirming its long range land use development goals and policies in the reviews and approvals with which it is faced. Accordingly, the Village Board has established a short moratorium on development approval and has commissioned Frederick P. Clark Associates, Community Planning and Development Consultants, to assist in reviewing and updating the Village Plan." When one reviews this document, one finds clear articulation of many of the Village's policies, goals and objectives. For example, on page 5 of this study, in describing the southern portion of the Village, the document states, "The plan for the area should therefore focus on the stability of existing development areas, the potential development of the remaining undeveloped parcels and the appropriateness of any redevelopment within the Ridge Street corridor." (emphasis added) Hawthorne Avenue directly abuts North Ridge Street. The Hawthorne Avenue Area Study now underway is consistent not only with the municipality's responsibility to manage growth while preserving the character and values of existing neighborhoods, but the study is consistent with the goals articulated in the earlier 1986 study in that the purpose of this 1994 study is to analyze and develop strategies to promote the "stability" of the existing developed Hawthorne Avenue area and to plan to ensure "the appropriateness of any redevelopment" that may be proposed for this area. 3 Additionally, it should be noted that the relative lack of undeveloped parcels located within the southern portion of the Village acts to intensify pressures for redevelopment, regardless of whether that redevelopment is in the best interest of preserving the character and value of existing neighborhoods. Under the "Planning Goals and Policies" section of the 1986 report (page 15), a number of policies and goals for residential development are articulated. These include the following: "Maintain and protect residential character of existing residential areas within the study area... "Encourage the development of a broad range of housing types to meet the needs of the Village..." We believe these policies and goals are very much applicable to the Hawthorne Avenue area today. Clearly, Hawthorne Avenue constitutes an existing, unique and very attractive residential area. It is unique in that it is the only area in the southern portion of the Village where a concentration of large older homes can be found on relatively large lots. In this way, Hawthorne Avenue clearly acts to provide diversity to the Village center's housing types. While the northern and central portions of the Village maintain neighborhoods developed with newer large homes on relatively large lots, Hawthorne Avenue is unique within the Village's southern end where a development pattern dominated by smaller lot single- and two-family residential development exists. 0 Additionally, it should be noted that nowhere else in the entire Village can one find an area with such a substantial collection of large older houses on larger lots. Consequently, preserving this unique, attractive area is consistent with the Village's stated goal of maintaining diversity of housing types within various areas of the Village. The Village's concern for promoting the legitimate governmental interest of protecting the viability and character of existing stable residential areas is evident throughout other parts of the 1986 Village Plan analysis as well. For example, in discussing commercial development along Westchester Avenue and North Ridge Street (page 19), the 1986 report states, "This plan recommends a land use and development policy that would in general contain these commercial areas to their present boundaries since their expansion would otherwise encroach upon existing stable residential areas." (emphasis added) Since Hawthorne Avenue abuts both Westchester Avenue and North Ridge Street, it was plainly neighborhoods such as Hawthorne Avenue, if not Hawthorne Avenue itself, that the Village was concerned about protecting when this section of the memorandum was drafted. This theme is echoed again on page 20 of the 1986 report where, in discussing potential redevelopment of properties along Westchester Avenue between the Port Chester line and Ridge Street (i.e. where Hawthorne Avenue is located), the memorandum speaks of the goal of "protect(ing) the basic residential character and values of the interior neighborhood." Continuing on page 20, the memorandum goes on to list some suggested standards for this goal. The first of these standards states, "Basic objectives should be established, 5 such as maintenance of property values, preservation of adjacent residential property value, maintenance of individual site viability and reduction of traffic safety hazards." (emphasis added) Based upon our review of the Rye Brook Center Development Plan Update: Preliminary Report, it appears clear that the Village, almost since its inception, has remained steadfastly wed to its obligation to preserve and protect the character and value of established residential neighborhoods, whether that character and value might be threatened by inappropriate commercial or residential development. B. Existing zoning With the exception of its southern end, the entire study area is zoned R-7 (see Figure 1). As currently drafted, the R-7 zoning standards permit the creation of single family homes on lots that maintain a minimum area of 7,500 square feet, a minimum mean lot width of 60 feet and a minimum mean lot depth of 100 feet. Additionally, principal structures located within those lots must maintain a minimum front yard setback of 25 feet, a minimum rear yard setback of 20 feet and side yard setbacks requiring that neither side shall maintain less than 8 feet of setback from the side lot line and that the combined minimum setbacks for the two side yards shall be not less than 20 feet. The southern quarter of the study area is zone R -2F. The R -2F zoning district's standards permit one- or two-family homes to be developed on lots comprised of a minimum of 5,000 square feet and which maintain a minimum mean lot width of 50 feet and a minimum mean lot depth of 100 feet. Additionally, the principal structure is required to maintain a minimum front yard setback of 20 feet, a minimum single side yard setback of 0 six feet, a minimum combined side yard setback of 16 feet and a minimum rear yard setback of 30 feet. C. Study Area Development Pattern The boundaries of the Hawthorne Avenue study area were determined by two factors: the existing R-7 zoning district surrounding much of Hawthorne Avenue; and those lots not located within the R-7 zoning district but which maintained frontage on Hawthorne Avenue or reasonably could be perceived as part of the "gateway" to Hawthorne Avenue (see Figure 1). While the study area was established, in part, based upon a long history of concern that there may exist a problem with the underlying zoning along Hawthorne Avenue and, therefore, there was a need to study all of Hawthorne Avenue as well as the small portion of the R-7 zoning district that extended west from the Hawthorne Avenue lots to North Ridge Street, the reality is that the land use dynamics within the study area vary considerably depending upon where in the study area a particular lot is located. Generally speaking, the lots with frontage on North Ridge Street and/or gaining access from North Ridge Street tend to be medium-sized and are of a distinctly different character than the lots located on the interior portions of Hawthorne Avenue. The North Ridge Street lots range in size from about 8,000 square feet to about 23,000 square feet with the average lot size being approximately 12,000 square feet. While the Study Area's North Ridge Street lots are significantly oversized (average of 50%+ larger than the minimum lot size standard of the applicable zoning district (R-7), the disparity between existing average lot size and zoning standard minimum lot size is even greater as it applies to Hawthorne Avenue lots. 7 r� di a Lu L x. 10 •- IRENHYL AVENUE RA1 wFSTO�FS7FR ElStudy Area HAWTHORNE AVE.

The lots located at the southern end of Hawthorne Avenue have, to greater and lesser extents, been colored by the Westchester Avenue development pattern of higher density residential uses interspersed with non-residential uses along a major thoroughfare. Similarly, the two lots located along the eastern side of the northern end of Hawthorne Avenue have been developed in a pattern more similar to that of the adjoining neighborhoods located across Irenhyl Avenue and to the north and east of Hawthorne Avenue then they are similar to those lots located along the interior portion of Hawthorne Avenue. The lots fronting along the interior portions of Hawthorne Avenue range in size from a minimum of about 9,000 square feet to a maximum of about 60,000, with the average lot size being approximately 23,000 square feet, or more than three times the minimum lot size (3000+) of the host zoning district (R-7). Within this area of oversized lots, large stately homes have been developed for the most part (see Figures 2, 3 and 4). The homes tend to be setback from the street by thirty feet or more, maintain minimal side yards and large rear yard recreation areas. In addition to being large, many of these homes appear significantly older and more architecturally diverse than those in the surrounding neighborhoods (see Figures 5 and 6). Even a cursory review of the tax maps for this area readily reveals the disparity in lot sizes between those located throughout the bulk of Hawthorne Avenue and those located on the adjoining and surrounding streets (see Figure 1). Furthermore, as is evidenced by Figures 1 through 6, the location and the style of dwelling units placed upon the lots of the streets surrounding Hawthorne Avenue are distinctly 3 25 HAWTHORNE AVENUE 5 HAWTHORNE AVENUE HAWTHORNE AVE.

It should also be noted that there is no other single area within the Village of Rye Brook where large, older single family homes predominate. While the middle and northern portions of the Village do maintain areas where newer larger homes abound, there is no area in the southern portion of the Village where larger single family homes on larger lots predominate and no area within the entire Village with such a collection of older large homes. D. Zoning Standards vs Development Pattern(s) 1. Overview: Table 1 has been prepared to show the relative magnitude of non-compliance that exists under the study area's current zoning of R-7 and R -2F. A cautionary note is in order with regard to the tables and associated calculations presented in this report. The tables and calculations have been prepared utilizing the preliminary tax maps of the Town of Rye. The maps are working drafts and the scale of the maps is such that highly detailed work is not possible based upon these maps. However, we believe the maps serve a valid purpose in assessing generally the relative compatibility of the established development pattern within the Hawthorne Avenue study area relative to the existing underlying zoning and any potential zoning amendments that might be applied to this area. We, therefore, believe the tables are valuable tools in assessing the relative magnitude of the appropriateness of any given zoning classification to the general area under study. 01 TABLE 1 HAWTHORNE AVENUE STUDY AREA LOT STUDY ANALYSIS(1) EXISTING CONDITIONS (R-7 AND R -2F) COMPLIANCE ANALYSIS Source: Preliminary (not approved) Tax Maps of the Town of Rye; measurements approximated by Frederick P.

In addition to providing an overview of the general magnitude of compliance versus non-compliance that would occur under each of these zoning districts, the tables also provide a useful tool in helping to identify where certain zoning districts might be appropriate to certain sub -areas of the study area. Used in coordination with other land use planning tools, we believe the tables provide a good overview of the development pattern existent within the study area and its relative compatibility with various rezoning scenarios. However, a second cautionary note is appropriate at this time with regard to the measurement of average lot width. As explained in more detail below, the Village of Rye Brook Code currently requires that lot width be calculated based upon the mean average width of a lot. Particularly with lots such as those that exist along Hawthorne Avenue, which are significantly over -sized, considerably deeper than they are wide and have a slanted rear lot line, the affect of requiring that lot width be determined on the basis of a mean average is such that the numerical lot width average actually understates the lot width that is existent within the body of most of the developable portion of the lot. In other words, the average lot width measurements of Tables 1 through 6, 8 10 TABLE 2 HAWTHORNE AVENUE STUDY AREA LOT STUDY ANALYSIS(1) R-5 COMPLIANCE ANALYSIS BLOCK/ LOT #(2) LOT AREA AVG.

This has resulted in a situation where some non -conformities are identified based upon a technical requirement of the Code rather than the substantive goal of insuring that a lot maintains a certain amount of width throughout the body of its developable area. Recognizing this deficiency, the Rye Brook Zoning Update Committee and the Rye Brook Planning Board have been studying amendments to the Bulk Regulations of the Village of Rye Brook designed specifically to remedy this technical weakness in the definition of how lot width and depth must be measured in the Village of Rye Brook. Consequently, it may be that these tables somewhat overstate the actual number of non -complying situations that would occur under any given regulatory scheme. 2. Existing Regulations: Table 1 demonstrates that a number of non -conforming situations exist even under the existing zoning (most of the Study Area being zoned R-7 with the remainder zoned R -2F). 3. Single Family Residential Districts: Tables 2 through 6 identify the level of non -conformity that would be brought to the area by rezoning the entire area to any other single family residential zoning district in the Village. As would be expected, Tables 2 through 6 demonstrate that the number of non -conformities increase as larger lot zoning is applied. E. Recommendations As one begins to examine the study area in depth, two things become apparent. First, although most of this area is located 11 within one zoning district and most of the area is already developed, the pattern of development within the study area varies considerably. Second, the area has been developed in a manner not generally consistent with either its underlying zoning or with the body of bulk standards applicable to any zoning district currently existing within the Village of Rye Brook. That is to say, while many of the lots meet the minimum lot area requirement of the R-20 Zoning District, and even more of the lots meet the minimum lot area standard of the R-15 District, the pattern of development that has emerged along the bulk of Hawthorne Avenue, with its large houses placed on very large lots with deep rear yards, often minimal side yards and moderate front yards, is not consistent with the setback standards applicable to the R-20 or R-15 Districts. Similarly, although the mean and median average lot sizes are both in excess of 20,000 square feet, these lots generally do not meet the minimum mean lot width standards of either the R-20 or R-15 Districts and have considerably more depth than is required under the minimum mean lot depth standards applicable to either Rye Brook's R-20 or R-15 Zoning Districts. Consequently, after studying and analyzing the impacts of rezoning the central Hawthorne Avenue area to one of the Village's existing zoning districts, this office determined that while the R-15 District's bulk standards constituted the best "fit" between the underlying development pattern and the Village's existing bulk zoning standards, such a rezoning actually would not establish a very good match between the proposed zoning standards and the existing development pattern. While we have briefly presented for your review our analysis of the impact of rezoning the central Hawthorne Avenue portion of the study area to R-15 (see Figure 7 and Table 8), it is our recommendation that the Village Board of Trustees consider the creation of a new zoning district (R- 12 IT—G L L' L If c Y Study Area —_ R1, a [_ Zoning District Boundary iL '� 14/7 Block B Lot Numbers ' T IRENHYL AVENUE R.15 One Family Residence I- ° —�, 15.000 Sq.Ft.

Such a zoning district should attempt to reflect the central Hawthorne Avenue area's large lot/smaller front and side yard setback pattern of development. But, before entering into a detailed discussion of the relative merits of creating a new R -15A Zoning District for the central Hawthorne Avenue portion of the study area, we believe it is best if we present our recommendations with regard to the other portions of the study area. It is our recommendation that the lots located within the study area be divided among several zoning districts, including the R -2F, R- 5, R-7 and a newly created R -15A Zoning Districts, all as shown on Figure 8 and further explicated on Table 9. We recommend that Lots 15/34A and 14/10B -2-C, which are located in the extreme southeastern and southwestern corners of the study area respectively, remain within the R -2F zoning district. One of these lots is slightly less than 8,000 square feet in size and the other is slightly less than 5,000 square feet in size. Not only are the lots relatively small by comparison to the study area's average lot size, but these lots are located along Westchester Avenue and clearly are developed in a style consistent with the development pattern along this major thoroughfare. Similarly, we would recommend that Lots 15/1A and 15/1B be rezoned from their present R-7 classification to an R-5 classification. These lots are each about 5,000 square feet in size. Lot 15/1A maintains frontage on Irenhyl Avenue and both Lots 15/1A and 15/1B have been developed in a pattern consistent with that which exists within the R-5 District that adjoins these lots to the north and east of these properties. 13 0 RA1 L11iL L -'Lz.

Part R-7 and Part R-5; all to R -15A 500yye4-20A.tg We recommend that Lots 14/19A through 14/23 remain within their current R-7 zoning district. Each of these lots maintains frontage on North Ridge Street and/or gains access from North Ridge Street. North Ridge Street is a major thoroughfare whose character is distinctly dissimilar from the quiet residential character of Hawthorne Avenue. Furthermore, while a few of these lots are substantially over -sized relative to the R-7 zoning district lot area standard, the majority of these lots are about 8,000 or 9,000 square feet in size. Although this would create a relatively small pocket of R-7 zoning within the Village, we believe this is the best designation for this area. While these lots could be zoned to R -2F by enlarging the existing R -2F zoning district that is located immediately to the south of these lots, we do not believe that creating additional traffic and parking demand along North Ridge Street would be advisable. On -street parking is not available in this area and increasing the number of traffic conflicts along the multiple curb cuts located in this vicinity would not be advisable either. Consequently, we recommend that these lots remain within their present R-7 zoning district classification. Lastly, we recommend that the remaining lots, which encompass all of the lots on either side of Hawthorne Avenue except for Lots 14/lOB-2-C, 15/1A and 15/1B, be rezoned from their current R-7 zoning classification to a newly created R -15A zoning classification. These lots maintain an estimated mean average lot size of almost 23,000 square feet and an estimated median size of a little more than 23,000 square feet. Consequently, we see that, based upon lot size alone, a zoning designation of R-20 (20,000 -square foot minimum lot size) might be appropriate for this portion of the Hawthorne Avenue study area. 14 However, the bulk standards of the Zoning Law applicable to single-family residential development contain restrictions beyond just lot area (see Table 7). Hawthorne Avenue has generally been developed with very deep lots maintaining as much as 100 feet of width through most of their depth. While the R-7 district contemplates lot widths of as little as 60 feet, the R-20 zoning district contemplates lots with a minimum width of 125 feet. While the minimum mean lot width standard for the R-15 district is 100 feet, the configuration of the widest lots on Hawthorne Avenue (i.e. slanted rear lot lines) has resulted in a situation where these lots do not maintain a mean lot width of 100 feet. But, as alluded to above, the mean, or average, lot width of many of the lots along Hawthorne Avenue is slightly less than 100 feet due to the fact that the rear lot lines of these lots are oriented in such a manner that one side of the lot is deeper than the other. This results in a situation where the lot becomes narrower in its rear -most portion. While this has no practical impact on the ability to develop the lot (especially due to the fact that this rear -most portion of the lot would be used only for buffering and/or passive and active outdoor recreational activities), this does create a technical lot width problem in that this narrow portion of the lot is computed as part of the mean lot width calculations and thus makes the lot appear - on paper - as though it were less than 100 feet wide. It should also be noted that, in most cases, the narrower portion of these lots is comprised of an area above and beyond the area that is needed to satisfy the minimum lot area requirement of the proposed new R -15A Zoning District. Table 8 identifies the non -conformities that are projected to exist if the central Hawthorne Avenue portion of the study area is rezoned to R-15, which we believe represents the best 15 match between the underlying development pattern in this area and the bulk standards of zoning districts now existing in the Village of Rye Brook. We have identified this rezoning scenario as "Option 1." Table 8 identifies not only the non - conformities that the Option 1 rezoning would create, but also �! identifies situations where a non -conformity would occur regardless of whether the rezoning recommended herein is adopted. Several items are worth noting with regard to Table 8. The vast majority of average lot width deficiencies that would be created if the proposed rezoning were adopted are technical deficiencies only. That is, as detailed above, they are created due to the fact that the rear portions of the subject lots becomes narrower than the rest of the lot due to the orientation of the rear lot line. Consequently, from a planning perspective, we do not consider these average lot width deficiencies to be substantially problematic to the use or further development of these lots. Furthermore, most, although not all, of the setback deficiencies that would be created under the proposed zoning consist of situations where the existing setback is already deficient. Consequently new deficiencies would not generally be created, although the magnitude of some existing deficiencies would be increased and, in a few cases, additional deficiencies would be created. Nevertheless, it is not generally considered advisable to zone an existing developed area in such a manner as to create a great number of non -conformities. Consequently, although we do not believe that the non -conformities that would be created under the R-15 rezoning scenario would be significantly problematic for any individual homeowner with regard to the use or redevelopment of their lot, we do not think it is owl V advisable to engage in a rezoning where a substantial portion of the area proposed for rezoning is rendered non -conforming. When rezoning an established, desirable and attractive area, the zoning, quite simply, should better fit the underlying development pattern than is possible by just applying the current R-15 bulk standards. Utilizing the Town of Rye preliminary tax maps, we have estimated that there are 24 existing bulk standard non - conformities within the study area. Under the rezoning scenario described above with the central Hawthorne Avenue portion of the study area rezoned to R-15, the total number of non -conformities would rise to an estimated 52, or an estimated net increase of 28 non -conformities. Furthermore, whereas an estimated 16 of the lots within the study area currently maintain one or more bulk standard non -conformities, the rezoning scenario described above, inclusive of the R-15 rezoning, would increase the number of lots maintaining non - conformities to an estimated 26 (a 62.5% increase). By comparison, if the rezoning scenario was done as described above but, instead of the existing R-15 Zoning District, an R - 15A Zoning District (rezoning Option 2) was established with a minimum lot area of 15,000 square feet, an average lot depth standard of 130 feet, an avera a lot width standard of 80 feet, a front yard setback st d d of 30 feet, a single side yard setback of 10 feet, a c bi d side yard setback of 20 feet, and a rear yard setback o 6 eet, the estimated number of bulk standard non-conformit'es would increase from the current level of 24 non -conformities to an estimated 36 bulk standard non -conformities (see Table 9). Furthermore, the total number of lots containing one or more non -conformities would increase by just two lots under the proposed Option 2 (R -15A zoning standards) scenario (a 12.5% increase). 17 Although the option 2 rezoning would result in a modest increase in the number of non -conformities on these pre- existing developed lots, we do not see this situation as particularly problematic due to the fact that any structural improvement that was legally constructed prior to a rezoning of this area would be "grandfathered" and thereby protected. Consequently, the non -conformities would only impact a property owner under one of two circumstances. If that property owner decided to expand the structure, and thereby potentially increase the non -conformity, the property owner would either have to obtain a variance or increase the structure's size in an area that did not require a variance (i.e. within the R -15A building setback lines). The second problem that potentially could occur would be that if a structure were substantially damaged (more than 50 percent of the structure's assessed valuation) by fire or other disaster, then the property owner could not rebuild the property in its original form absent the granting of a variance by the Zoning Board of Appeals. The issue of whether the Zoning Board of Appeals would find that the tests required to grant a bulk variance had been met in such a situation would be entirely within the Zoning Board of Appeals' purview. Aside from the fact that the creation of the R -15A Zoning District would result in fewer non -conformities than would the direct application of the existing R-15 Zoning District bulk standards, we believe the creation of the R -15A Zoning District is superior in that it is more specifically tailored to the unique qualities that have been established in the development pattern of Hawthorne Avenue and have resulted in Hawthorne Avenue's highly attractive and desirable streetscape. It must be remembered that while redevelopment potential does exist within this neighborhood, and would exist under the proposed rezoning, the area has an established development pattern that has been deemed attractive and worthy F[7 of preservation. Consequently, the regulatory structure — inclusive of its zoning standards — should be designed so as to match, complement and encourage this desirable development pattern to the maximum extent practicable. To this end, we are recommending that the above noted rezoning scenario, Option 2, inclusive of the creation and application of the new R -15A standards, be applied to this area. However, we are further recommending that Chapter 153, Lot Area Coverage, of the Code of the Village of Rye Brook be amended to add the R -15A Zoning District to Section 153-3 Schedule of the Lot Area Coverage law. The setbacks proposed within the R -15A bulk standards described above have been designed to encompass the wide variety of setbacks that have been established on Hawthorne Avenue. However, this means that the front and side yard setbacks are relatively small. Consequently, if one were to use the setback standards as building envelopes to be filled by a disproportionately large structure rather than as boundaries designed to provide flexibility of house siting, the result could be the creation of a very bulky structure that was entirely out of character with the area. This, too, could be detrimental to the express purpose of the rezoning: to preserve the unique and attractive character of the area while still permitting reasonable development and redevelopment. Consequently, we have performed an analysis of the lot coverages of the principle and accessory structures located within the area proposed for rezoning to R -15A. Based upon this analysis, we are recommending that Section 153-3 of the Lot Area Coverage Law of the Village of Rye Brook be amended as shown below with the shaded materials identifying items to be added to Section 153-3. 19 LOT AREA COVERAGE STANDARDS Zone District Area (square feet) Main Building Accessory Building Decks Maximum Percent Square Feet Maximum Percent Square Feet Maximum Percent Square Feet R -2F 5,000 30 1,500 5 250 3.5 175 R-5 5,000 30 1,500 5 250 3.5 175 R-7 7,500 23 1,725 4.5 338 3.5 225 R-10 10,000 1 20 2,000 4.5 1 450 3.5 350 R-12 12,500 17 2,125 4 500 4 500 R-15 15,000 16 2,400 3.5 700 4 800 R�15A 15,000 12 1,800 315 525 k 600 R-20 20,000 14 2,800 3.5 700 4 800 As you can see from the above indicated additions to Section 153-3, this office is recommending that the R -15A Zoning District identify a maximum main building coverage of 12 percent. On a 15,000 square foot lot, this would translate into an 1,800 square foot building footprint or, with a two- story structure, a 3,600 square foot home, not including basement and attic areas. Based upon the average lot size existing within the proposed R -15A area of approximately 23,000 square feet, this would translate into a maximum building footprint of approximately 2,760 square feet or a slightly larger than 5,500 square foot home, excluding basement and attic areas. Most of the 22 principle structures located on lots recommended to be rezoned to R -15A maintain principle building coverage percents of between 5 and 9 percent. However, 4 of the 22 lots would not comply with the proposed principle building coverage requirement. We note, though, that three of these four non -conformities would occur on lots that are undersized relative to the proposed R -15A minimum lot area standard. These three lots are generally about 30 percent 20 undersized and maintain existing principle building coverages ranging from about 13 percent to about 16 percent. The one remaining building that would be rendered non -conforming is the very large (3,000+ square foot footprint) building located at the northeast quadrant of the intersection of Hawthorne Avenue and Westchester Avenue. This structure maintains a building coverage of approximately 12.4 percent. We would also recommend that accessory buildings be limited to a maximum of 3.5 percent of building coverage. Most of the accessory buildings located on these lots maintain lot coverages of between one-half percent and three percent. Only one accessory structure would exceed the maximum percent coverage permitted. We believe that a 3.5 percent coverage maximum is appropriate given that this would result in a 525 square foot accessory structure on a 15,000 square foot lot. Such a structure is approximately the size of a small studio apartment or three - car garage. The average lot size of 23,000 square foot would permit an accessory structure of more than 800 square feet which is enough to support a four -car garage. We believe that these lot area coverages provide ample opportunity for as -of -right development and redevelopment within the area proposed to be rezoned to R -15A. However, given that there would be a few lots that would not comply with this requirement, we are further recommending that the Lot Area Coverage Law should be incorporated within the Zoning Law of the Village of Rye Brook. This is important not only for the Hawthorne Avenue area but for the entire Village. Given that the Lot Area Coverage Law is not currently a part of the Zoning Law, it does not appear that one can obtain relief from these standards from the Zoning Board of Appeals. 21 Lot Area Coverage is really a zoning bulk standard and it is treated as such in most communities. The Lot Area Coverage Law, as currently drafted, appears to provide no release valve for those specific circumstances where hardship or other situations might warrant variance with the requirements of the law. For this reason, we would recommend that the Lot Area Coverage Law be deleted from the Code and that the Zoning Law be amended to incorporate the standards of the Lot Area Coverage Law. It is our recommendation that the zoning law be amended to include the R -15A bulk standards identified above, that the zoning map be amended to rezone the study area in the manner described in Option 2 above and that the lot area coverage law be amended and incorporated within the zoning law as described above. The above noted zoning changes and the creation of the R -15A, in concert with application of the new lot area coverage standards, should act to ensure the preservation of the unique and desirable character of the Hawthorne Avenue area while still permitting development of undeveloped lots, redevelopment of existing lots and expansion of existing structures all in a manner designed to be compatible with that which is virtually universally considered to be an attractive and desirable part of the Village. III. CONCLUSION It is our professional judgement that the current zoning applicable to much of the Hawthorne Avenue Study Area is not consistent the area's established development pattern. It is also abundantly clear that Hawthorne Avenue is a very attractive street that constitutes a valuable asset to the Village in that it contains some of the Village's most beautiful homes, provides a very attractive streetscape and, in various ways, provides diversity of 22 housing types both for the southern part of the Village and for the Village as a whole. Future redevelopment on any of this relatively short street's oversized lots in a manner consistent with the R-7 district's standards of relatively small houses placed on relatively small lots could be expected to act to erode the street's special character and, possibly, the neighborhood's stability. Furthermore, a substantial amount of such redevelopment could be expected to encourage more of the same and, thereby, potentially set into motion a spiraling effect of ever further erosion of the area's special character. Therefore, consistent with a municipality's responsibility to preserve the quality of its neighborhoods and protect its assets, we recommend that the Village act to rezone the area as identified above. cc: Christopher Russo Rocco Circosta Kenneth Powell 500\rye3-077.t9:aj:ev Thomas Gissen, AICP 23
