Highpointe Crossing - 2298 Inwood Ave N – Lake Elmo – Preliminary Plat Narrative June 7, 2024 Page 20 20 • Impervious o A typical OP-PUD limits impervious surfaces to 25% of the lot area including streets and trails. We are unsure of the reason for this stricter standard since over 50% of the property will be deep rooted prairie open space and water running off from the impervious surfaces will be treated within the storm water ponds. That said since our lots are smaller there will be a need for a higher percentage of impervious. We are asking for an allowance of up to 50% impervious on the homesites. While some lots will need up to 50% impervious, most lots will likely need less. Below is a table with hard cover examples based on models that Charles Cudd is planning to build within the neighborhood. These are modest sized homes in the luxury villa category. You will see that without a pool most lots, not all, will be able to accommodate the largest of the planned Cudd home models. If a customer wants a pool, the size of the pool deck could eliminate some of the smaller homesites. We are ok that not all lots will accommodate a pool. Without a pool most lots work with most models so some lots may not accommodate a pool. Still there are some lots where 50% may not work for certain models and just like the examples with the pools, compromises will need to be made or customers who want larger homes will need to look to the larger lots. The examples below are conservative. We believe that when all is said and done the overall hardcover of the property including sidewalks and roads will be under 15%. However, if all lots use up their 50% hardcover the neighborhood including streets, sidewalk and the county road turn lanes will be 18.64% hardcover.
