RCA Attachment A 164 perceived impact on backyard privacy of a new street being built too close to an existing rear lot line, 165 staff spent this short time focused on the question of how to quantify “too close,” which led to the 166 proposed amendment staff forwarded to the Planning Commission for consideration. 167 Given the additional time to consider how best to address the undesirable qualities of through lots and 168 the Planning Commission’s discussion, however, staff would suggest consideration of a different 169 approach to an amendment. Rather than focusing on some minimum separation between existing lots 170 and a proposed new street, Planning Division staff has arrived at the perspective that robust screening is 171 much more important. Adequate screening can eliminate the privacy concerns more effectively and 172 efficiently than increasing the distance by some arbitrary amount, although additional separation might 173 also be a function of this approach, which could look like the following. 174 The Definition: 175 An interior lot having a pair of opposing lot lines along, and access to, two more or less parallel public 176 streets, or a corner lot having streets on at least three sides, with access to at least two of those streets 177 that are more-or-less parallel. 178 The Regulations: 179 a.Through lots, as defined in Title 10, Zoning, shall be prohibited. 180 b.Notwithstanding this prohibition, the creation of through lots may be considered where one or 181 both of the following circumstances are present: 182 i.Topographic or other conditions render subdividing otherwise unreasonable. 183 ii.A proposed new street would be substantially in alignment with the existing street network. 184 c.If a plat is approved pursuant to the preceding provision, and said plat includes a new street 185 which creates one or more though lots of existing residential parcels adjacent to the plat, 186 landscaping and fencing shall be installed as may be necessary to mitigate potential noise and 187 privacy impacts to the through lot rear yards. 188 i.In the case of a private street, such screening shall be installed by the developer in a platted 189 outlot of at least 20 feet in width between the rear line of such through lot(s) and the adjacent 190 street, and shall be maintained by an association of property owners along the private street. 191 ii.In the case of a public street, additional right-of-way shall be dedicated as may be necessary 192 to accommodate the required screening, which shall be maintained by City of Roseville. 193 iii.Such screening shall not be required if the new street is located a distance from the other 194 more or less parallel street that is equal to or greater than twice the distance necessary to 195 meet the minimum area requirement for two hypothetical lots of the minimum required width 196 that could be situated between the two streets. 197 d.Because through lots have access to streets at the front and back, vehicular access to such lots 198 shall be gained from the roadway of lower functional classification or as otherwise approved by 199 the City Engineer. 200 P OLICY O BJECTIVE 201 Develop programs and policies to encourage the redevelopment of housingstock in a way that maintains 202 or enhances the integrity of existing neighborhoods. 203 B UDGET I MPLICATIONS 204 none PROJ0042_Amdt1_ThroughLots_RCA_20200928 Page 5 of 6 Page 5 of 9
